[PATCH plinth/topic-sas-5.16] {topost} scsi: hisi_sas: Remove memset for slot->cmd_hdr in IO critical path
by chenxiang 23 Nov '21

23 Nov '21

From: Xiang Chen <chenxiang66(a)hisilicon.com> For ssp and stp commands, most fields of slot->cmd_hdr will be overwrote by function prep_ssp_v3_hw() and prep_ata_v3_hw(), so it is not necessary to memset them in front, and just write dw7 and sg_len to 0 for them (dw5 is alway 0). For smp and abort commands, they are not used frequently and most fields of them are not overwrote, so memset slot->cmd_hdr separately for them.

[PATCH net] page_pool: Revert "page_pool: disable dma mapping support..."
by Yunsheng Lin 18 Nov '21

18 Nov '21

This reverts commit d00e60ee54b12de945b8493cf18c1ada9e422514. As reported by Guillaume in [1]: Enabling LPAE always enables CONFIG_ARCH_DMA_ADDR_T_64BIT in 32-bit systems, which breaks the bootup proceess when a ethernet driver is using page pool with PP_FLAG_DMA_MAP flag. As we were hoping we had no active consumers for such system when we removed the dma mapping support, and LPAE seems like a common feature for 32 bits system, so revert it. 1. https://www.spinics.net/lists/netdev/msg779890.html Fixes: d00e60ee54b1 ("page_pool: disable dma mapping support for 32-bit arch with 64-bit DMA") Signed-off-by: Yunsheng Lin <linyunsheng(a)huawei.com> --- include/linux/mm_types.h | 13 ++++++++++++- include/net/page_pool.h | 12 +++++++++++- net/core/page_pool.c | 10 ++++------ 3 files changed, 27 insertions(+), 8 deletions(-) diff --git a/include/linux/mm_types.h b/include/linux/mm_types.h index bb8c6f5f19bc..c3a6e6209600 100644 --- a/include/linux/mm_types.h +++ b/include/linux/mm_types.h @@ -105,7 +105,18 @@ struct page { struct page_pool *pp; unsigned long _pp_mapping_pad; unsigned long dma_addr; - atomic_long_t pp_frag_count; + union { + /** + * dma_addr_upper: might require a 64-bit + * value on 32-bit architectures. + */ + unsigned long dma_addr_upper; + /** + * For frag page support, not supported in + * 32-bit architectures with 64-bit DMA. + */ + atomic_long_t pp_frag_count; + }; }; struct { /* slab, slob and slub */ union { diff --git a/include/net/page_pool.h b/include/net/page_pool.h index 3855f069627f..a4082406a003 100644 --- a/include/net/page_pool.h +++ b/include/net/page_pool.h @@ -216,14 +216,24 @@ static inline void page_pool_recycle_direct(struct page_pool *pool, page_pool_put_full_page(pool, page, true); } +#define PAGE_POOL_DMA_USE_PP_FRAG_COUNT \ + (sizeof(dma_addr_t) > sizeof(unsigned long)) + static inline dma_addr_t page_pool_get_dma_addr(struct page *page) { - return page->dma_addr; + dma_addr_t ret = page->dma_addr; + + if (PAGE_POOL_DMA_USE_PP_FRAG_COUNT) + ret |= (dma_addr_t)page->dma_addr_upper << 16 << 16; + + return ret; } static inline void page_pool_set_dma_addr(struct page *page, dma_addr_t addr) { page->dma_addr = addr; + if (PAGE_POOL_DMA_USE_PP_FRAG_COUNT) + page->dma_addr_upper = upper_32_bits(addr); } static inline void page_pool_set_frag_count(struct page *page, long nr) diff --git a/net/core/page_pool.c b/net/core/page_pool.c index 9b60e4301a44..1a6978427d6c 100644 --- a/net/core/page_pool.c +++ b/net/core/page_pool.c @@ -49,12 +49,6 @@ static int page_pool_init(struct page_pool *pool, * which is the XDP_TX use-case. */ if (pool->p.flags & PP_FLAG_DMA_MAP) { - /* DMA-mapping is not supported on 32-bit systems with - * 64-bit DMA mapping. - */ - if (sizeof(dma_addr_t) > sizeof(unsigned long)) - return -EOPNOTSUPP; - if ((pool->p.dma_dir != DMA_FROM_DEVICE) && (pool->p.dma_dir != DMA_BIDIRECTIONAL)) return -EINVAL; @@ -75,6 +69,10 @@ static int page_pool_init(struct page_pool *pool, */ } + if (PAGE_POOL_DMA_USE_PP_FRAG_COUNT && + pool->p.flags & PP_FLAG_PAGE_FRAG) + return -EINVAL; + if (ptr_ring_init(&pool->ring, ring_qsize, GFP_KERNEL) < 0) return -ENOMEM; -- 2.33.0

[PATCH net-next v6] page_pool: disable dma mapping support for 32-bit arch with 64-bit DMA
by Yunsheng Lin 17 Nov '21

17 Nov '21

As the 32-bit arch with 64-bit DMA seems to rare those days, and page pool might carry a lot of code and complexity for systems that possibly. So disable dma mapping support for such systems, if drivers really want to work on such systems, they have to implement their own DMA-mapping fallback tracking outside page_pool.

[RFCv4 PATCH net-next] net: extend netdev_features_t
by Jian Shen 10 Nov '21

10 Nov '21

For the prototype of netdev_features_t is u64, and the number of netdevice feature bits is 64 now. So there is no space to introduce new feature bit. This patchset try to solve it by change the prototype of netdev_features_t from u64 to structure below: typedef struct { DECLARE_BITMAP(bits, NETDEV_FEATURE_COUNT); } netdev_features_t; With this change, it's necessary to introduce a set of bitmap operation helpers for netdev features. As the nic drivers are not supposed to modify netdev_features directly, it also introduces wrappers helpers to this. There are a set of helpes named as "netdev_features_xxx", and I want to add similar helpers for netdev features members, named as netdev_XXX_features_xxx.(xxx: and/or/xor.., XXX: hw/vlan/mpls...) To make the helpers name differentiable, rename netdev->features to netdev->active_features. For example: #define netdev_active_features_set_bit(ndev, nr) \ netdev_features_set_bit(nr, &ndev->active_features) To avoid mistake using NETIF_F_XXX as NETIF_F_XXX_BIT as input macroes for above helpers, remove all the macroes of NETIF_F_XXX. The features group macroes in netdev_features.h are replaced by a set of const features defined in netdev_features.c. For example: macro NETIF_F_ALL_TSO is replaced by netdev_all_tso_features The whole work is not complete yet. I just use these changes on HNS3 drivers and part of net/core/dev.c, in order to show how these helpers will be used. I want to get more suggestions for this scheme, any comments would be appreciated. The former discussion please see [1][2].

[RFCv3 PATCH net-next] net: extend netdev_features_t
by Jian Shen 01 Nov '21

01 Nov '21

For the prototype of netdev_features_t is u64, and the number of netdevice feature bits is 64 now. So there is no space to introduce new feature bit. This patchset try to solve it by change the prototype of netdev_features_t from u64 to structure below: typedef struct { DECLARE_BITMAP(bits, NETDEV_FEATURE_COUNT); } netdev_features_t; With this change, it's necessary to introduce a set of bitmap operation helpers for netdev features. As the nic drivers are not supposed to modify netdev_features directly, it also introduces wrappers helpers to this. The whole work is not complete yet. I just use these changes on HNS3 drivers and part of net/core/dev.c, in order to show how these helpers will be used. I want to get more suggestions for this scheme, any comments would be appreciated. The former discussion please see [1].

[PATCH] Revert "iommu/arm-smmu-v3: Decrease the queue size of evtq and priq"
by Zhou Wang 15 Oct '21

15 Oct '21

The commit f115f3c0d5d8 decreases evtq and priq, which may lead evtq/priq to be full with fault events, e.g HiSilicon ZIP/SEC/HPRE have maximum 1024 queues in one device, every queue could be binded with one process and trigger a fault event. So let's revert f115f3c0d5d8. In fact, if an implementation of SMMU really does not need so long evtq and priq, value of IDR1_EVTQS and IDR1_PRIQS can be set to proper ones.

04 Oct '21

Greetings dear This letter might be a surprise to you, But I believe that you will be honest to fulfill my final wish. I bring peace and love to you. It is by the grace of god, I had no choice than to do what is lawful and right in the sight of God for eternal life and in the sight of man for witness of god’s mercy and glory upon my life. My dear, I sent this mail praying it will find you in a good condition, since I myself am in a very critical health condition in which I sleep every night without knowing if I may be alive to see the next day. I am Mrs.Hannah Vandrad, a widow suffering from a long time illness. I have some funds I inherited from my late husband, the sum of ( Eleven Million Dollars) my Doctor told me recently that I have serious sickness which is a cancer problem. What disturbs me most is my stroke sickness. Having known my condition, I decided to donate this fund to a good person that will utilize it the way I am going to instruct herein. I need a very honest and God fearing person who can claim this money and use it for Charity works, for orphanages and gives justice and help to the poor, needy and widows says The Lord." Jeremiah 22:15-16.“ and also build schools for less privilege that will be named after my late husband if possible and to promote the word of god and the effort that the house of god is maintained. I do not want a situation where this money will be used in an ungodly manner. That's why I'm taking this decision. I'm not afraid of death, so I know where I'm going. I accept this decision because I do not have any child who will inherit this money after I die. Please I want your sincere and urgent answer to know if you will be able to execute this project, and I will give you more information on how the fund will be transferred to your bank account. May the grace, peace, love and the truth in the Word of god be with you and all those that you love and care for. I am waiting for your reply. May God Bless you, Mrs. Hannah Vandrad.

Hi
by Grace Johnson 30 Sep '21

30 Sep '21

How are you doing? I want to share a message that has been spreading all over the internet that concerns the times we are living in. Whether you believe in God or not, this is a must read message! We can see throughout time how we have been slowly conditioned to come to this point where we are on the verge of a cashless society. Would it surprise you to know that the Bible foretold of this event? Don't believe me? This may be the most imporant message you will read in these times...please do not ignore this! This messsage reveals what the Mark of the Beast is, and the meaning behind counting a number people have been pondering for centuries, 666. This message also shares why Barack Obama is the Antichrist as well as the gospel message. This is truly a message from God! In the Revelation of Jesus Christ given to the apostle John, we read: ...."And he (the false prophet who deceives many by his miracles) causeth all, both small and great, rich and poor, free and bond, to receive a mark in their right hand, or in their foreheads: And that no man might buy or sell, save he that had the mark, or the name of the beast, or the number of his name. Here is wisdom. Let him that hath understanding count the number of the beast: for it is the number of a man; and his number is Six hundred threescore and six" (Revelation 13:16-18 BRG)..... Referring to the last generation, this could only be speaking of a cashless society. Why? Revelation 13:17 tells us that we cannot buy or sell unless we receive the mark of the beast. If physical money was still in use, we could buy or sell with one another without receiving the mark. This would contradict scripture. So, it deduces itself to this conclusion. These verses could not be referring to something spiritual as scripture references two physical locations (our right-hand or forehead) stating the mark will be on one "OR" the other. It once again deduces itself to this conclusion. Also, how could you determine who truly has a spiritual mark so that they may buy or sell? And, as you will read further in this message, to have the mark of the beast is the same to have the name of the beast, and the number of its name. You will begin to see even more clearly why this mark cannot be something purely spiritual. Here is where it really starts to come together. It is shocking how accurate the Bible is concerning the RFID microchip. These are notes from a man named Carl Sanders who worked with a team of engineers to help develop this microchip in the late 1960's. Carl Sanders attended 17 New World Order meetings with heads-of-state officials such as Henry Kissinger and Bob Gates of the CIA to talk about plans on how to bring forth this one-world system. The US government commissioned Carl Sanders to design a microchip for identifying and controlling the peoples of the nations-a microchip that could be inserted under the skin with a hypodermic needle (a quick, convenient procedure that would be gradually accepted by the people). Carl Sanders, along with a team of engineers with him, with U.S. grant monies supplied by tax dollars, took on this mission and designed a microchip which is powered by a lithium battery, rechargeable with the aid of the temperature changes in our skin. With out the knowledge of the holy Bible (Mr. Sanders was not a Christian at the time), these engineers spent one and a half million dollars gathering information on the best and most convenient spot to have the microchip placed under the skin. These researchers found that the forehead and the back of the hand (the two spots Revelation says the mark will be received) aren't just the most convenient places, however are also the only viable spots for constant, consistent temperature changes in the skin to recharge the lithium battery. The microchip is about 7 millimeters in length, .75 millimeters in diameter, about the size of a grain of rice. It is capable of containing many pages of data about you. All your basic information, work information, crime history, health history, and financial history could be stored on this chip. Carl Sanders believes that this microchip, which he remorsefully helped engineer, is the "beast's mark" spoke of in Revelation 13:16-18. The original Greek word for "mark" is "charagma," which means a "scratch or etching." Additionally it is fascinating to note that the number 666 is actually a word in the original Greek language. That word is "chi xi stigma," with the final word, "stigma," also meaning "to stick or prick. Mr. Sanders believes that is referring to the usage of a hypodermic needle being poked into the human flesh to insert the microchip." Mr. Sanders asked a Boston Medical Center doctor what would happen if the lithium contained within the RFID microchip leaked into the body. The doctor responded that if the microchip broke inside a human body, the lithium would cause a severe and painful wound filled with pus. This is what the book of Revelation says: "And the first (angel) went, and poured out his bowl into the earth; and it became a noisome and grievous sore upon the men that had the mark of the beast, and that worshipped his image" (Revelation 16:2 ASV). THE HIDDEN MEANING BEHIND THE NUMBER 666 REVEALED! What I first want to mention, before I share what the Holy Spirit has revealed to me concerning the number of the beast, is that God confirms in threes. We can see this throughout scripture: "For there are three that bear witness in heaven: the Father, the Word, and the Holy Spirit; and these three are one" (1 John 5:7 NKJV). "and that He was buried, and that He rose again the third day according to the Scriptures" (1 Corinthians 15:4 NKJV). "...Holy, holy, holy, Lord God Almighty, Who was and is and is to come!" (Revelation 4:8 NKJV). There are many more examples, but I thought I would just share three of them to make the point. Examining Revelation 13:16,17,18, the first group of three I would like to point out is that the mark of the beast is described in three separate verses, 16, 17 and 18. The next three I see is in verse 16, "He causes all..." is followed by three contrasting categories of people, 1 - "both small and great, 2 - rich and poor, 3 - free and slave...". Then unto verse 17, it opens with, "and that no one may buy or sell except one who has...", followed by three explanations of what one must have to buy or sell, 1 - "...the mark 2 - or the name of the beast, 3 - or the number of his name". Now unto verse 18, we read "Let him who has understanding calculate...", which is followed by, 1 - "the number of the beast, 2 - for it is the number of a man: 3 - His number is 666". The last three I see is the number "6" being used three times in a row. The reason I'm making this point about God confirming in three is because it is the key to unlocking how to calculate the number 666. Throughout the centuries there have been people trying to calculate numbers based on titles and names that come up to the number 666 to identify one person, the Antichrist; but from Revelation 13:18, I do not see where God is telling us to count up to 666, but rather to count the number of the beast. This number is identified as 666. So the verse is telling us to count the number 666. What does it mean to count? It means to add up. So how could we add up 666? Remember my previous point about God confirming in threes is key to unlocking the number 666. So logically, what would be the best way to count the number 666? To count it equally by using the rule of three based off the number. We cannot count it equally as 600+60+6, this would also bring us back to the start. We cannot count it as 600+600+600, or 60+60+60 because there are no zeroes in between or at the end of 666. The only logical option is 6+6+6=18. What is interesting is that the verse that reveals for us to count the number itself is verse 18 (there a total of 18 verses in Revelation Chapter 13), being the third verse out of the three verses that describe the mark of the beast in Revelation 13:16,17,18. What is 18 divided by 3? 6. So 3x6=18, or 6+6+6=18. Another interesting point is the only two other combinations (making a total of three possible combinations) for placing a "+" symbol in between 666 are: • 66+6=72 and 6+66=72. • Add both 72's together and you get 144. Why the number 144 is worth our attention is because the verse following Revelation 13:18 is the first time in the Bible where the 144,000 are being described in detail: "Then I looked, and behold, a Lamb standing on Mount Zion, and with Him one hundred and forty-four thousand, having His Father’s name written on their foreheads..." (Revelation 14:1). Now if you add up all three numbers from counting 666 by moving the "+" symbol around, it would be 72+72+18=162. What is compelling about the number 162, is, if you divide 144,000 by 162, you get 888. The name of Jesus in Greek gematria adds up to 888. The New Testament was originally written in the Greek language. Revelation 14:1 not only mentions the 144,000, but also the Lamb who is Jesus. Now what is interesting about the number for Jesus, 888, is that if you apply the same formula that was used to count 666, you get 8+8+8=24. Why the number 24? Revelation chapter 4 tells us there are 24 elders seated around the throne of God. This is the same throne where Jesus sits. Now if you take: • 8+8+8=24 • 8+88=96 • 88+8=96 you get 24+96+96=216. Take 144,000 divided by 216 and you get 666. Remember that this was the same exact formula we used to count the number 666 that ultimately brought forth the number 888. Here is a quick recap to demonstrate how this formula confirms itself as being the true way to count 666: 1: 6+6+6=18 » 66+6=72 » 6+66=72 » 18+72+72=162 2: 144,000 divided by 162=888 3: 8+8+8=24 » 88+8=96 » 8+88=96 » 24+96+96=216 4: 144,000 divided by 216=666 1: 6+6+6=18 » 66+6=72... As you can see, it is perpetual. And remember that we consistently used a formula that worked in threes being the number that God uses for confirmation. By utilizing the same formulation of counting by including the plus symbol in between the numbers, why do all these numbers relate in such a manner? The book of Revelation contains the use of the number 7 in various forms. For instance 7 seals, 7 trumpets, and 7 bowls. What is interesting about the number 37 (three sevens) is if if you divide any number that contains the same single digit three times in a row, such as 111 to 999, it comes out to the value of if you were to add all three numbers up. For example 888 divided by 37 equals 24. So 8+8+8=24. Or 666 divided by 37 equals 18. So 6+6+6=18. Could this be another way of God's word confirming itself that the mystery behind calculating the number 666 indeed is 18? Another fascinating factor to note is that if you add up all the numbers from 1 to 36 (1+2+3...+36), it totals 666. The number 36, as in three sixes? May this be a hint that we need to add up three sixes as opposed to perceiving the number as six-hundred sixty six? So what may this suggest? We know in this world we are identified by numbers in numerous forms. Starting from our birth certificate to our social security card, also with our drivers license, being identified based on a system of ruler ship. So it's possible that this RFID microchip will contain a brand new identification that has a total of 18 characters. "here the wisdom is, the one having the mind let him calculate the number of the wild beast, number for "of human" it is, and the number of it 666" (Revelation 13:1, Greek Translation). The Greek word "anthrōpos" being used in verse 18 where it says "of human" is the Greek strongs concordance G444. The first two definitions of the word are "a human being, whether male or female", and, "generically, to include all human individuals". Could the number of the beast apply to all mankind? In the Greek (the New Testament was originally written in the Greek language), and other translations, you will notice the beast is described as an "it", instead of "him". The reason I'm making this point is because when a translation says "His number is 666", this would imply a singular person, the Antichrist. But by saying "the number of it 666", implies that it is of the beast system as a whole. We can know the number of the beast cannot be to identify products (like a new barcode) to buy or sell because scripture says we cannot buy or sell without the number of the beast. What am I getting at? There will be instances where you could buy something someone made themselves and it wouldn't have a store branded identification on it. But for this number to be in our chips, that is where it must be to conclude ultimately that we cannot buy or sell without having the number of the beast. As previously mentioned in Revelation 13:18, the number of the beast (6+6+6=18) is a "human number", definition "generically, to include all human individuals". May this be the identification of the beast, the number of its name? The one-world beast system which is identified by 18 characters? This might fit the scriptures that speaks of a mark that we ought to have to buy or sell in our right-hand or forehead, and that it also incorporates the number of the beast, during a future cashless money society. Here is another mathematical confirmation: 144,000 divided by 6, divided by 6, divided by 6 (6,6,6) equals 666. To see many more of these amazing calculations, read the article about the RFID Mark of the Beast and the number 666... Do we believe blind forces gave us eyes to see? That deaf forces gave us ears to hear? That careless forces gave us a heart to care for others? That faithless forces uphold the universe and all the laws that govern it and that is why we should trust them? That mindless forces gave us a mind to think and comprehend these things? If there is a God, He must be personal, because we as His creation are personal beings. How do we get to personally know anybody? By their word...The words of Jesus have been translated into over 2,000 languages, and nothing comes remotely close (the Quran about 110). If that is not God's word, nothing is. Why? Why would a personal loving God who desires for us to know Him, who is all powerful, allow man to create a word far surperior than His to be spread around the world throughout time in so many different languages to deceive the world so we may not know the truth about Him? God has shown me some time ago that Trump will have a second term (he will be back soon!), and that this will be the time where the two witnesses of Revelation 11 will rise up (who are the 144,000) to prophesy for 42 months to every tribe, tongue, nation and people before the beast rises from the sea in Revelation 13. We will see His Holy Spirit move across the world in a mighty way bringing a great multitude to God. God gave me a vision that Obama will be back in 2024.

If you feel led to, please forward this email to your friends and family so they may know that God is moving in these times in mighty ways, even through His prophets to proclaim the truth of His word to the ends of the earth. God bless! "Why did the Biden campaign choose 30330? 2020 divided by 666 = 3.0330 Who believes this to be a coincidence? October 2020 Isaiah 53:6 Someone said we are being whipsawed in 2020. Truly a great division is taking place between good and evil—both symbolically and literally (riots, unrest, politics). If you take the current year 2020 and divide it by the number 666 (known for its satanic implications) you will get the number 30330 (repeated). This number 30330 happens to be the number used to vote for Joe Biden and Kamala Harris. Freaky? Supernatural? Odd for sure. Whatever this means, it doesn’t seem good to me. First, why would anyone knowingly choose those particular numbers for their campaign? If they weren’t knowingly chosen, then it appears to be a supernatural act by the evil one himself and I would want to change those numbers ASAP. And if the numbers were chosen knowing their significance, are you satanic? Is this campaign satanic? Either way I do not believe this is a coincidence. And one thing is certain, 2020 is truly being divided by Satan. He is the master deceiver and spreader of chaos. Jesus calls him the father of lies." So I looked up this number 30330 concerning Joe Biden, and I found this information: If you send a text to that number (at that time), you would get a response asking to support Joe's campaign to take down Donald Trump, with one part in caps saying "CHIP IN >>" pointing to a link to go and donate. "CHIP IN"? Obama has used this phrase in the past on his twitter and people believe it is a subliminal message to receive the mark of the beast, that is to say the implantable RFID microCHIP that will go IN our body. God's word warns us in the end times that a false prophet will stand up doing miraculous signs to deceive many to acquire the beasts mark: ...."And the beast was taken, and with him the false prophet that wrought the signs in his sight, wherewith he deceived them that had received the mark of the beast and them that worshipped his image: they two were cast alive into the lake of fire that burneth with brimstone" (Revelation 19:20 ASV).... At all costs, DO NOT TAKE IT! "Then a third angel followed them, saying with a loud voice, "If anyone worships the beast and his image, and receives his mark on his forehead or on his hand, he himself shall also drink of the wine of the wrath of God, which is poured out full strength into the cup of His indignation. He shall be tormented with fire and brimstone in the presence of the holy angels and in the presence of the Lamb. And the smoke of their torment ascends forever and ever; and they have no rest day or night, who worship the beast and his image, and whoever receives the mark of his name" (Revelation 14:9-11). We're living in very prophetic times with major Biblical prophecies coming to pass. When Donald Trump recognized Jerusalem as capital of Israel on December 6 2017, this was a big step to bring forth the Third Temple prophesied in the Bible. God's Holy scriptures tells us that the Antichrist will seat himself in this temple: "...and the man of sin is revealed, the son of perdition, who opposes and exalts himself above all that is called God or that is worshiped, so that he sits as God in the temple of God, showing himself that he is God" (2 Thessalonians 2:3-4). Within the Islamic faith, there is a figure called the Mahdi, referred to as their messiah who they're awaiting to appear. There are many testimonies from individuals on line who consider this man will be Barack Obama who may be the biblical Antichrist. I myself have had unusual dreams (you can read them in my article on the website above) concerning Barack. He came on stage claiming to be a follower of Christ with no affiliation to the Muslim religion, however it was later revealed by his circle of relatives that he indeed is a religious Muslim. So what's in the name? The meaning of someones name can say a lot about a person. God throughout history has given names to people that have a specific meaning tied to their lives. How about the name Barack Obama? Let us take a look at what may be hiding beneath the surface... Jesus says, "And He said to them, 'I saw Satan fall like lightning from heaven'" (Luke 10:18). In Hebrew, the word "Barack" means "lighting", and the use of "Bama" (Strongs Hebrew word 1116) is used to mean the "heights" of heaven. The day after the election of Barack Obama (11/04/08), the triumphing pick three lotto numbers in Illinois (Obama’s home state) for 11/5/08 were 666. Obama was a U.S. senator for Illinois, and his zip code was 60606. The names of both of Obama's daughters are Malia and Natasha. If we were to write those names backwards we would get "ailam ahsatan". Now if we remove the letters that spell "Alah" (Allah being the God of Islam), we get "I am Satan". Coincidence? I don't think so. These are just a few of many evidences why Barack Obama is the Antichrist. You can see many more in my article on the website above, as well as read about the dreams I've had concerning this man. I'm more than convinced that God has shown me that he is without a doubt the Antichrist, and we will see him rise to power in the not so dinstant future. Why do we need Jesus? "for all have sinned and fall short of the glory of God" (Romans 2:23). "For the wages of sin is death, but the gift of God is eternal life in Christ Jesus our Lord" (Romans 6:23). Our good works cannot save our souls. If we step in front of a judge, being responsible for committing a crime, the judge is not going to judge us by the good that we have accomplished, rather the crimes we have committed. If we as fallen humanity, created in God's image, pose this type of justice, how much more a perfect, righteous, and Holy God? God has introduced to us His moral law's by the ten commandments handed to Moses at Mt. Siani. These legal guidelines were not given so we can be justified, but in order that we might see the need for our saviour. They're the mirror of God's character of what He has put in each and every one of us, with our conscious bearing witness that we know that it's wrong to steal, lie, dishonor our mother and father, and so on. We may attempt to follow all the moral laws of the ten commandments, but we will never catch up to them to be justified before a Holy God. That same word of the law received by Moses was brought forth as flesh over 2000 years ago in the body of Jesus Christ. He came to be our justification by perfectly fulfilling the commandments of God, living a sinless life that solely God may accomplish. The distance between us and the law of God can never be reconciled by our own merit, however the arm of Jesus is stretched out by the grace and mercy of God. And if we are to grab on, by faith in Him, He'll pull us forward being the one to justify us. As in the court of law, if someone steps in and pays your debt, despite the fact that you're guilty, the judge can do what is legal and just and set you free. That is what Jesus did almost 2000 years ago on the cross. It was a legal transaction being fulfilled in the spiritual realm by the shedding of His blood, with His last words being, "...It is finished!..." (John 19:30). So why did Jesus have to die for us? Because God is Holy and just, the wrath that we deserve could not be overlooked. Through the perfect righteousness and justice of God's character, it ought to be reconciled, it ought to be quenched and satisfied. For God takes no pleasure in the demise of the wicked (Ezekiel 18:23). That is why in Isaiah chapter 53, where it speaks of the coming Messiah and His soul being a sacrifice for our sins, why it says it pleased God to crush His only begotten Son. That is because the wrath that we deserve was justified by being poured out upon His Son. For if it was poured out upon us who have earned it, we'd all die and go to hell. God created a means of escape by pouring it out on His Son who's soul could not be left in Hades, but was raised and seated at the right hand of God in power. Now after we put on the Lord Jesus Christ (Romans 13:14), God no longer see's the person who deserves His wrath, but the glorious image of His perfect Son dwelling in us, justifying us as if we acquired the wrath we deserve, making a means of escape from the curse of death. Now what we ought to do is repent and believe in the saviour, confessing and turning from our sins. That is not just a head knowledge of believing in Jesus, but rather receiving His words, taking them to heart. Where we no longer live to practice sin, but turn from our sins and practice righteousness: "Do you not know that the unrighteous will not inherit the kingdom of God? Do not be deceived. Neither fornicators, nor idolaters, nor adulterers, nor homosexuals, nor sodomites, nor thieves, nor covetous, nor drunkards, nor revilers, nor extortioners will inherit the kingdom of God. And such were some of you. But you were washed, but you were sanctified, but you were justified in the name of the Lord Jesus and by the Spirit of our God" (1 Corinthians 6:9-11). By doing so we will become transformed into the image of God by faith in His Son Christ Jesus Who's willing to give the Holy Spirit to those that ask of Him: "Most assuredly, I (Jesus) say to you, unless one is born of water and the Spirit, he cannot enter the kingdom of God. That which is born of the flesh is flesh, and that which is born of the Spirit is spirit. Do not marvel that I said to you, 'You must be born again.' (John 3:5-6). "But you are not in the flesh but in the Spirit, if indeed the Spirit of God dwells in you. Now if anyone does not have the Spirit of Christ, he is not His" (Romans 8:9). What are you waiting for? Our Father in heaven only wants the best for us all, restoring all the pieces this world has stolen from us. That is what it means to be "holy". To be made whole. He's waiting to listen to you. That God given tongue to speak language, by way of faith, pray to Him, ask Him to forgive you by confessing to Him your sins and be willing to forsake them; that you accept the sacrifice of His Son Jesus on the cross, and that you want His Holy Spirit living inside you transforming you into a child of God. Jesus says, "but whoever drinks of the water that I shall give him (the Holy Spirit) will never thirst. But the water that I shall give him will become in him a fountain of water springing up into everlasting life." Did you realize that Jesus spoke more about hell than any one in God's holy word, even more than He spoke about heaven?! For this very purpose He came to die for us, to save us from this place that we earned by our sins against a holy God. He describes hell as a real place where, "Their worm does not die And the fire is not quenched" (Mark 9:44). And where, "There will be weeping and gnashing of teeth..." (Luke 13:28). Jesus tells us who to fear, "And do not fear those who kill the body but cannot kill the soul. But rather fear Him who is able to destroy both soul and body in hell" (Matthew 10:28). "Now I saw a new heaven and a new earth, for the first heaven and the first earth had passed away. Also there was no more sea. Then I, John, saw the holy city, New Jerusalem, coming down out of heaven from God, prepared as a bride adorned for her husband. And I heard a loud voice from heaven saying, 'Behold, the tabernacle of God is with men, and He will dwell with them, and they shall be His people. God Himself will be with them and be their God. And God will wipe away every tear from their eyes; there shall be no more death, nor sorrow, nor crying. There shall be no more pain, for the former things have passed away.' Then He who sat on the throne said, 'Behold, I make all things new.' And He said to me, 'Write, for these words are true and faithful.' And He said to me, 'It is done! I am the Alpha and the Omega, the Beginning and the End. I will give of the fountain of the water of life freely to him who thirsts. He who overcomes shall inherit all things, and I will be his God and he shall be My son. But the cowardly, unbelieving, abominable, murderers, sexually immoral, sorcerers, idolaters, and all liars shall have their part in the lake which burns with fire and brimstone, which is the second death.'" (Revelation 21:1-8).

[RFCv2 PATCH net-next 000/167] net: extend the netdev_features_t
by Jian Shen 26 Sep '21

26 Sep '21

For the prototype of netdev_features_t is u64, and the number of netdevice feature bits is 64 now. So there is no space to introduce new feature bit. This patchset try to solve it by change the prototype of netdev_features_t from u64 to bitmap. With this change, it's necessary to introduce a set of bitmap operation helpers for netdev features. Meanwhile, the functions which use netdev_features_t as return value are also need to be changed, return the result as an output parameter. With above changes, it will affect hundreds of files, and all the nic drivers. To make it easy to be reviewed, split the changes to 167 patches to 5 parts. patch 1~22: convert the prototype which use netdev_features_t as return value patch 24: introduce fake helpers for bitmap operation patch 25~165: use netdev_feature_xxx helpers patch 166: use macro __DECLARE_NETDEV_FEATURE_MASK to replace netdev_feature_t declaration. patch 167: change the type of netdev_features_t to bitmap, and rewrite the bitmap helpers.

[linuxarm] [PATCH v3] RDMA/hns: Add new mmap implementation
by Chengchang Tang 23 Sep '21

23 Sep '21

Add new implementation for mmap by using the new mmap entry API. Subsequent new features will use this new implementation. The old mmap which use a hard-corded offset will not be further expanded. And forward compatibility is also guaranteed in this patch.

[linuxarm] [PATCH v3 1/1] libhns: Add a new mmap mode
by Chengchang Tang 23 Sep '21

23 Sep '21

Add a new mmap mode support for hns. All the subsequent new features will be completed in a similar implementation of mmap. In the new mmap mode, the user space driver use the offset sent by kernel space driver to complete the mmap instead of a hard-coded offset. Forward compatibility is guaranteed in this patch.

[linuxarm] [PATCH v2] libhns: Add a new mmap mode
by Chengchang Tang 18 Sep '21

18 Sep '21

Add a new mmap mode support for hns. All the subsequent new features will be completed in a similar implementation of mmap. In the new mmap mode, the user space driver use the offset sent by kernel space driver to complete the mmap instead of a hard-coded offset. Forward compatibility is guaranteed in this patch.

I just want to inform you
by Godwin Pete 08 Sep '21

08 Sep '21

Hi, I just want to use this little opportunity to inform you about my success towards the transfer. I'm currently out of the country for an investment with part of my share, after completing the transfer with an Indian business man. But i will visit your country, next year. After the completion of my project. Please, contact my secretary to send you the (ATM) card which I've already credited with the sum of ($500,000.00). Just contact her to help you in receiving the (ATM) card. I've explained everything to her before my trip. This is what I can do for you because, you couldn't help in the transfer, but for the fact that you're the person whom I've contacted initially, for the transfer. I decided to give this ($500,000.00) as a compensation for being contacted initially for the transfer. I always try to make the difference, in dealing with people any time I come in contact with them. I'm also trying to show that I'm quite a different person from others whose may have a different purpose within them. I believe that you will render some help to me when I, will visit your country, for another investment there. So contact my secretary for the card, Her contact are as follows, Full name: Mrs, Jovita Dumuije, Country: Burkina Faso Email: jovitadumuije(a)gmail.com Thanks, and hope for a good corporation with you in future.

[PATCH net] net: hns3: add option to turn off page pool feature
by Yunsheng Lin 06 Sep '21

06 Sep '21

When page pool is added to the hns3 driver, it is always enabled unconditionally, which means spilt page handling in the hns3 driver is dead code. As there is a requirement to test the performance between spilt page handling in driver and page pool, so add a module param to support disabling the page pool. When the page pool is proved to be perform better in most case, the spilt page handling in driver can be removed.

[PATCH net-next 000/143] net: extend the netdev_features_t
by Jian Shen 18 Aug '21

18 Aug '21

For the prototype of netdev_features_t is u64, and the number of netdevice feature bits is 64 now. So there is no space to introduce new feature bit. This patchset try to solve it by change the prototype of netdev_features_t from u64 to bitmap. With this change, it's neccessary to introduce a set of bitmap operation helpers for netdev features. Meanwhile, the functions which use netdev_features_t as return value are also need to be changed, return the result as an output parameter. With above changes, it will affect hundreds of files, and all the nic drivers. To make it easy to be reviewed, split the changes to 124 patches to 6 parts. patch 1: code optimization for hns3 driver patch 2~23: convert the prototype which use netdev_features_t as return value patch 24: introduce fake helpers for bitmap operation patch 25~141: use netdev_feature_xxx helpers patch 142: use macro __DECLARE_NETDEV_FEATURE_MASK to replace netdev_feature_t declaration. patch 143: change the type of netdev_features_t to bitmap, and rewrite the bitmap helpers.

[PATCH net-next 0/4] ethtool: extend coalesce uAPI
by Yufeng Mo 18 Aug '21

18 Aug '21

In order to support some configuration in coalesce uAPI, this RFC extends coalesce uAPI and add support for CQE mode. Below is some test result with HNS3 driver: 1. old ethtool(ioctl) + new kernel: estuary:/$ ethtool -c eth0 Coalesce parameters for eth0: Adaptive RX: on TX: on stats-block-usecs: 0 sample-interval: 0 pkt-rate-low: 0 pkt-rate-high: 0 rx-usecs: 20 rx-frames: 0 rx-usecs-irq: 0 rx-frames-irq: 0 tx-usecs: 20 tx-frames: 0 tx-usecs-irq: 0 tx-frames-irq: 0 rx-usecs-low: 0 rx-frame-low: 0 tx-usecs-low: 0 tx-frame-low: 0 rx-usecs-high: 0 rx-frame-high: 0 tx-usecs-high: 0 tx-frame-high: 0 2. ethtool(netlink with cqe mode) + kernel without cqe mode: estuary:/$ ethtool -c eth0 Coalesce parameters for eth0: Adaptive RX: on TX: on stats-block-usecs: n/a sample-interval: n/a pkt-rate-low: n/a pkt-rate-high: n/a rx-usecs: 20 rx-frames: 0 rx-usecs-irq: n/a rx-frames-irq: n/a tx-usecs: 20 tx-frames: 0 tx-usecs-irq: n/a tx-frames-irq: n/a rx-usecs-low: n/a rx-frame-low: n/a tx-usecs-low: n/a tx-frame-low: n/a rx-usecs-high: 0 rx-frame-high: n/a tx-usecs-high: 0 tx-frame-high: n/a CQE mode RX: n/a TX: n/a 3. ethool(netlink with cqe mode) + kernel with cqe mode: estuary:/$ ethtool -c eth0 Coalesce parameters for eth0: Adaptive RX: on TX: on stats-block-usecs: n/a sample-interval: n/a pkt-rate-low: n/a pkt-rate-high: n/a rx-usecs: 20 rx-frames: 0 rx-usecs-irq: n/a rx-frames-irq: n/a tx-usecs: 20 tx-frames: 0 tx-usecs-irq: n/a tx-frames-irq: n/a rx-usecs-low: n/a rx-frame-low: n/a tx-usecs-low: n/a tx-frame-low: n/a rx-usecs-high: 0 rx-frame-high: n/a tx-usecs-high: 0 tx-frame-high: n/a CQE mode RX: off TX: off 4. ethool(netlink without cqe mode) + kernel with cqe mode: estuary:/$ ethtool -c eth0 Coalesce parameters for eth0: Adaptive RX: on TX: on stats-block-usecs: n/a sample-interval: n/a pkt-rate-low: n/a pkt-rate-high: n/a rx-usecs: 20 rx-frames: 0 rx-usecs-irq: n/a rx-frames-irq: n/a tx-usecs: 20 tx-frames: 0 tx-usecs-irq: n/a tx-frames-irq: n/a rx-usecs-low: n/a rx-frame-low: n/a tx-usecs-low: n/a tx-frame-low: n/a rx-usecs-high: 0 rx-frame-high: n/a tx-usecs-high: 0 tx-frame-high: n/a Change log from RFC: V3 -> V4: add document explaining the difference between CQE and EQE in #1 suggested by Jakub Kicinski. V2 -> V3: 1. split #1 into adding new parameter and adding new attributes. 2. use NLA_POLICY_MAX(NLA_U8, 1) instead of NLA_U8. 3. modify the description of CQE in Document. V1 -> V2: refactor #1&#2 in V1 suggestted by Jakub Kicinski.

In order to support some configuration in coalesce uAPI, this RFC extends coalesce uAPI and add support for CQE mode. Below is some test result with HNS3 driver: 1. old ethtool(ioctl) + new kernel: estuary:/$ ethtool -c eth0 Coalesce parameters for eth0: Adaptive RX: on TX: on stats-block-usecs: 0 sample-interval: 0 pkt-rate-low: 0 pkt-rate-high: 0 rx-usecs: 20 rx-frames: 0 rx-usecs-irq: 0 rx-frames-irq: 0 tx-usecs: 20 tx-frames: 0 tx-usecs-irq: 0 tx-frames-irq: 0 rx-usecs-low: 0 rx-frame-low: 0 tx-usecs-low: 0 tx-frame-low: 0 rx-usecs-high: 0 rx-frame-high: 0 tx-usecs-high: 0 tx-frame-high: 0 2. ethtool(netlink with cqe mode) + kernel without cqe mode: estuary:/$ ethtool -c eth0 Coalesce parameters for eth0: Adaptive RX: on TX: on stats-block-usecs: n/a sample-interval: n/a pkt-rate-low: n/a pkt-rate-high: n/a rx-usecs: 20 rx-frames: 0 rx-usecs-irq: n/a rx-frames-irq: n/a tx-usecs: 20 tx-frames: 0 tx-usecs-irq: n/a tx-frames-irq: n/a rx-usecs-low: n/a rx-frame-low: n/a tx-usecs-low: n/a tx-frame-low: n/a rx-usecs-high: 0 rx-frame-high: n/a tx-usecs-high: 0 tx-frame-high: n/a CQE mode RX: n/a TX: n/a 3. ethool(netlink with cqe mode) + kernel with cqe mode: estuary:/$ ethtool -c eth0 Coalesce parameters for eth0: Adaptive RX: on TX: on stats-block-usecs: n/a sample-interval: n/a pkt-rate-low: n/a pkt-rate-high: n/a rx-usecs: 20 rx-frames: 0 rx-usecs-irq: n/a rx-frames-irq: n/a tx-usecs: 20 tx-frames: 0 tx-usecs-irq: n/a tx-frames-irq: n/a rx-usecs-low: n/a rx-frame-low: n/a tx-usecs-low: n/a tx-frame-low: n/a rx-usecs-high: 0 rx-frame-high: n/a tx-usecs-high: 0 tx-frame-high: n/a CQE mode RX: off TX: off 4. ethool(netlink without cqe mode) + kernel with cqe mode: estuary:/$ ethtool -c eth0 Coalesce parameters for eth0: Adaptive RX: on TX: on stats-block-usecs: n/a sample-interval: n/a pkt-rate-low: n/a pkt-rate-high: n/a rx-usecs: 20 rx-frames: 0 rx-usecs-irq: n/a rx-frames-irq: n/a tx-usecs: 20 tx-frames: 0 tx-usecs-irq: n/a tx-frames-irq: n/a rx-usecs-low: n/a rx-frame-low: n/a tx-usecs-low: n/a tx-frame-low: n/a rx-usecs-high: 0 rx-frame-high: n/a tx-usecs-high: 0 tx-frame-high: n/a Change log: V3 -> V4: add document explaining the difference between CQE and EQE in #1 suggested by Jakub Kicinski.

Below is some test result with HNS3 driver: 1. old ethtool(ioctl) + new kernel: estuary:/$ ethtool -c eth0 Coalesce parameters for eth0: Adaptive RX: on TX: on stats-block-usecs: 0 sample-interval: 0 pkt-rate-low: 0 pkt-rate-high: 0 rx-usecs: 20 rx-frames: 0 rx-usecs-irq: 0 rx-frames-irq: 0 tx-usecs: 20 tx-frames: 0 tx-usecs-irq: 0 tx-frames-irq: 0 rx-usecs-low: 0 rx-frame-low: 0 tx-usecs-low: 0 tx-frame-low: 0 rx-usecs-high: 0 rx-frame-high: 0 tx-usecs-high: 0 tx-frame-high: 0 2. ethtool(netlink with cqe mode) + kernel without cqe mode: estuary:/$ ethtool -c eth0 Coalesce parameters for eth0: Adaptive RX: on TX: on stats-block-usecs: n/a sample-interval: n/a pkt-rate-low: n/a pkt-rate-high: n/a rx-usecs: 20 rx-frames: 0 rx-usecs-irq: n/a rx-frames-irq: n/a tx-usecs: 20 tx-frames: 0 tx-usecs-irq: n/a tx-frames-irq: n/a rx-usecs-low: n/a rx-frame-low: n/a tx-usecs-low: n/a tx-frame-low: n/a rx-usecs-high: 0 rx-frame-high: n/a tx-usecs-high: 0 tx-frame-high: n/a CQE mode RX: n/a TX: n/a 3. ethool(netlink with cqe mode) + kernel with cqe mode: estuary:/$ ethtool -c eth0 Coalesce parameters for eth0: Adaptive RX: on TX: on stats-block-usecs: n/a sample-interval: n/a pkt-rate-low: n/a pkt-rate-high: n/a rx-usecs: 20 rx-frames: 0 rx-usecs-irq: n/a rx-frames-irq: n/a tx-usecs: 20 tx-frames: 0 tx-usecs-irq: n/a tx-frames-irq: n/a rx-usecs-low: n/a rx-frame-low: n/a tx-usecs-low: n/a tx-frame-low: n/a rx-usecs-high: 0 rx-frame-high: n/a tx-usecs-high: 0 tx-frame-high: n/a CQE mode RX: off TX: off 4. ethool(netlink without cqe mode) + kernel with cqe mode: estuary:/$ ethtool -c eth0 Coalesce parameters for eth0: Adaptive RX: on TX: on stats-block-usecs: n/a sample-interval: n/a pkt-rate-low: n/a pkt-rate-high: n/a rx-usecs: 20 rx-frames: 0 rx-usecs-irq: n/a rx-frames-irq: n/a tx-usecs: 20 tx-frames: 0 tx-usecs-irq: n/a tx-frames-irq: n/a rx-usecs-low: n/a rx-frame-low: n/a tx-usecs-low: n/a tx-frame-low: n/a rx-usecs-high: 0 rx-frame-high: n/a tx-usecs-high: 0 tx-frame-high: n/a Change log: V2 -> V3: 1. split #1 into adding new parameter and adding new attributes. 2. use NLA_POLICY_MAX(NLA_U8, 1) instead of NLA_U8. 3. modify the description of CQE in Document. V1 -> V2: refactor #1&#2 in V1 suggestted by Jakub Kicinski.
