[PATCH openEuler-1.0-LTS 01/75] net: hns3: change hclge/hclgevf workqueue to WQ_UNBOUND mode
From: Yufeng Mo moyufeng@huawei.com
driver inclusion category: bugfix bugzilla: NA CVE: NA
----------------------------
Currently, the workqueue of hclge/hclgevf is executed on the CPU that initiates scheduling requests by default. In stress scenarios, the CPU may be busy and workqueue scheduling is completed after a long period of time. To avoid this situation and implement proper scheduling, use the WQ_UNBOUND mode instead. In this way, the workqueue can be performed on a relatively idle CPU.

Currently, affinity_mask is set to a single value. As a result, irqbalance becomes invalid in SUBSET or EXACT mode. To solve this problem, change affinity_mask to a value range. In this way, irqbalance can be performed on the CPU of the NUMA node.

----------------------------
hclge_dbg_reg_info[] is defined as an array of packed structure accidentally. However, this array contains pointers, which are no longer aligned naturally, and cannot be relocated on PPC64. Hence, when compile-testing this driver on PPC64 with CONFIG_RELOCATABLE=y (e.g. PowerPC allyesconfig), there will be some warnings.
Since each field in structure hclge_qos_pri_map_cmd and hclge_dbg_bitmap_cmd is type u8, the pragma packed is unnecessary for these two structures as well, so remove the pragma packed in hclge_debugfs.h to fix this issue, and this increases hclge_dbg_reg_info[] by 4 bytes per entry.

mainline inclusion from mainline-v5.14-rc1 commit 060e9accaa74 category: feature bugzilla: NA CVE: NA
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?i...
----------------------------------------------------------------------
The struct hclge_vf_vlan_cfg is firstly designed for setting VLAN filter tag. And it's reused for enable RX VLAN offload later. It's strange to use member "is_kill" to indicate "enable". So redefine the struct hclge_vf_vlan_cfg to adapt it.
For there are already 3 subcodes being used in function hclge_set_vf_vlan_cfg(), use "switch-case" style for each branch, rather than "if-else". Also simplify the assignment for each branch to make it more clearly.

Currently the RSS commands of VF are using host byte order. According to the user manual, it should use little endian in the command to firmware. For the host and firmware are both using little endian, so it can work well in this case.
Do cleanup to make it more explicitly.

----------------------------
when skb->encapsulation is 0, skb->ip_summed is CHECKSUM_PARTIAL and it is udp packet, which has a dest port as the IANA assigned. the hardware is expected to do the checksum offload, but the hardware will not do the checksum offload when udp dest port is 6081.
This patch fixes it by doing the checksum in software.

----------------------------
When skb->ip_summed is CHECKSUM_PARTIAL, for non-tunnel udp packet, which has a dest port as the IANA assigned, the hardware is expected to do the checksum offload, but the hardware whose version is below V3 will not do the checksum offload when udp dest port is 4790.
So fixes it by doing the checksum in software for this case.

----------------------------
In order to query tm priority and qset for debugging, adds debugfs files tm_priority and tm_qset in newly created tm directory.
Unlike previous debugfs commands, these files just support read ops, so they only support to use cat command to dump their info.
The new tm file style is acccording to suggestion from Jakub Kicinski's opinion as link https://lkml.org/lkml/2020/9/29/2101.

mainline inclusion from mainline-v5.14-rc1 commit 5e69ea7ee2a6 category: feature bugzilla: NA CVE: NA
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?i...
----------------------------------------------------------------------
Currently, each debugfs command needs to create a file to get the information. To better support more debugfs commands, the debugfs process is reconstructed, including the process of creating dentries and files, and obtaining information.

From: Huazhong Tan tanhuazhong@huawei.com
mainline inclusion from mainline-v5.14-rc1 commit 77e9184869c9 category: feature bugzilla: NA CVE: NA
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?i...
----------------------------------------------------------------------
Currently, the debugfs command for bd info is implemented by "echo xxxx > cmd", and record the information in dmesg. It's unnecessary and heavy.
To improve it, add two debugfs directories "tx_bd_info" and "rx_bd_info", and create a file for each queue under these two directories, and query the bd info of specific queue by "cat tx_bd_info/tx_bd_queue*" or "cat rx_bd_info/rx_bd_queue*", return the result to userspace, rather than record in dmesg.
The display style is below: $ cat rx_bd_info/rx_bd_queue0 Queue 0 rx bd info: BD_IDX L234_INFO PKT_LEN SIZE... 0 0x0 60 60... 1 0x0 1512 1512...
$ cat tx_bd_info/tx_bd_queue0 Queue 0 tx bd info: BD_IDX ADDRESS VLAN_TAG SIZE... 0 0x0 0 0... 1 0x0 0 0...

----------------------------------------------------------------------
Currently, the debugfs command for mac list info is implemented by "echo xxxx > cmd", and record the information in dmesg. It's unnecessary and heavy. To improve it, create two files "uc" and "mc" under directory "mac_list" for it, and query mac list info by "cat mac_list/uc" and "mac_list/mc", return the result to userspace, rather than record in dmesg.
The display style is below: $ cat mac_list/uc UC MAC_LIST: FUNC_ID MAC_ADDR STATE pf 00:18:2d:00:00:71 ACTIVE
$ cat mac_list/mc MC MAC_LIST: FUNC_ID MAC_ADDR STATE pf 01:80:c2:00:00:21 ACTIVE

Currently, the debugfs command for loopback is implemented by "echo xxxx > cmd", and record the information in dmesg. It's unnecessary and heavy. To improve it, create a single file "loopback" for it, and query it by command "cat loopback", return the result to userspace, rather than record in dmesg.
The display style is below: $ cat loopback mac id: 0 app loopback: off serdes serial loopback: off serdes parallel loopback: off

Change to the "hclge_show_rst_info" in the "hclge_reset_err_handle", when the reset fails, display reset info immediately.

Currently, the debugfs command for m7 info is implemented by "echo xxxx > cmd", and record the information in dmesg. It's unnecessary and heavy. To improve it, create a single file "imp_info" for it, and query it by command "cat imp_info", return the result to userspace, rather than record in dmesg.
The display style is below: $cat imp_info offset | data 0x0000 | 0x00000000 0x00000000 0x0008 | 0x00000000 0x00000000 0x0010 | 0x00000000 0x00000001 0x0018 | 0x00000000 0x00000000 0x0020 | 0x00000000 0x00000000 0x0028 | 0x00000000 0x00000000 0x0030 | 0x00000000 0x00000000

----------------------------
A number of static variables were not modified. Make them const to allow the compiler to put them in read-only memory. In order to do so, constify a couple of input pointers as well as some local pointers. This moves about 35Kb to read-only memory as seen by the output of the size command.

----------------------------------------------------------------------
Currently, the debugfs command for reg is implemented by "echo xxxx > cmd", and record the information in dmesg. It's unnecessary and heavy. To improve it, create some files "bios_common/ssu/igu_egu/rpu/ncsi/rtc/ppp/rcb/tqp/mac" for it, and query it by command "cat xxx", return the result to userspace, rather than record in dmesg.
The display style is below: $ cat bios_common BP_CPU_STATE: 0x0 DFX_MSIX_INFO_NIC_0: 0xc000 DFX_MSIX_INFO_NIC_1: 0x0 DFX_MSIX_INFO_NIC_2: 0x0 DFX_MSIX_INFO_NIC_3: 0x0 DFX_MSIX_INFO_ROC_0: 0xc000 DFX_MSIX_INFO_ROC_1: 0x0 DFX_MSIX_INFO_ROC_2: 0x0 DFX_MSIX_INFO_ROC_3: 0x0

mainline inclusion from mainline-v5.14-rc1 commit 365e860aa7a7 category: feature bugzilla: NA CVE: NA
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?i...
----------------------------------------------------------------------
Currently, the debugfs command for reg dcb info is implemented by "echo xxxx > cmd", and record the information in dmesg. It's unnecessary and heavy. To improve it, create a single file "dcb" for it, and query it by command "cat dcb", return the result to userspace, rather than record in dmesg.
The display style is below: $ cat dcb qset_id roce_qset_mask nic_qset_mask qset_shaping_pass qset_bp_status 0000 0x1 0x1 0x1 0x0 0001 0x1 0x1 0x1 0x0 0002 0x1 0x1 0x1 0x0 0003 0x1 0x1 0x1 0x0 0004 0x1 0x1 0x1 0x0 0005 0x1 0x1 0x1 0x0 0006 0x1 0x1 0x1 0x0 0007 0x1 0x1 0x1 0x0 pri_id pri_mask pri_cshaping_pass pri_pshaping_pass 000 0x1 0x0 0x1 001 0x1 0x0 0x0 002 0x1 0x0 0x0 003 0x1 0x0 0x0 004 0x1 0x0 0x0 005 0x1 0x0 0x0 006 0x1 0x0 0x0 007 0x1 0x0 0x0 pg_id pg_mask pg_cshaping_pass pg_pshaping_pass 000 0x1 0x0 0x1

Currently, the debugfs command for queue map is implemented by "echo xxxx > cmd", and record the information in dmesg. It's unnecessary and heavy. To improve it, create a single file "queue_map" for it, and query it by command "cat queue_map", return the result to userspace, rather than record in dmesg.
The display style is below: $ cat queue_map local_queue_id global_queue_id vector_id 0 0 341

Currently, the debugfs command for tm map is implemented by "echo xxxx > cmd", and record the information in dmesg. It's unnecessary and heavy. To improve it, create a single file "tm_map" for it, and query it by command "cat tm_map", return the result to userspace, rather than record in dmesg.
As user can't specify queue id in cat command, driver will return info of all queue id.

From: Guangbin Huang huangguangbin2@huawei.com
mainline inclusion from mainline-v5.14-rc1 commit cad7c215a4b1 category: feature bugzilla: NA CVE: NA
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?i...
----------------------------------------------------------------------
Currently, user gets some tm info by implementing debugfs command "echo dump tm > cmd", this command will dump info in dmesg. It's unnecessary and heavy.
In addition, the info of this command mixes info of qset, priority, pg and port. Qset and priority have their own command to get info of themself, so can remove info of qset and priority from this command.
To optimize it, create two new files "tm_pg", "tm_port" in tm directory and use cat command to separately get info of pg and port.
The display style is below: $ cat tm_pg ID PRI_MAP MODE DWRR C_IR_B C_IR_U C_IR_S C_BS_B C_BS_S ... 00 0x1f dwrr 1 75 9 0 31 20 ...
$ cat tm_port IR_B IR_U IR_S BS_B BS_S FLAG RATE(Mbps) 75 9 0 31 20 1 200000

From: Guangbin Huang huangguangbin2@huawei.com
mainline inclusion from mainline-v5.14-rc1 commit 0e32038dc856 category: feature bugzilla: NA CVE: NA
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?i...
----------------------------------------------------------------------
Currently, user gets tc schedule info by implementing debugfs command "echo dump tc > cmd", this command will dump info in dmesg. It's unnecessary and heavy.
To optimize it, create a single file "tc_sch_info" and use cat command to get info. It will return info to userspace, rather than record in dmesg.
The display style is below: $ cat tc_sch_info enabled tc number: 4 weight_offset: 14 TC MODE WEIGHT 0 dwrr 25 1 dwrr 25 2 dwrr 25 3 dwrr 25 4 dwrr 0 5 dwrr 0 6 dwrr 0 7 dwrr 0

----------------------------------------------------------------------
Currently, user gets pause config by implementing debugfs command "echo dump qos pause cfg > cmd", this command will dump info in dmesg. It's unnecessary and heavy.
To optimize it, create a single file "qos_pause_cfg" in tm directory and use cat command to get info. It will return info to userspace, rather than record in dmesg.
The display style is below: $ cat qos_pause_cfg pause_trans_gap: 0x7f pause_trans_time: 0xffff

From: Guangbin Huang huangguangbin2@huawei.com
mainline inclusion from mainline-v5.14-rc1 commit 95b195869b7d category: feature bugzilla: NA CVE: NA
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?i...
----------------------------------------------------------------------
Currently, user gets qos buffer config by implementing debugfs command "echo dump qos buf cfg > cmd", this command will dump info in dmesg. It's unnecessary and heavy.
To optimize it, create a single file "qos_buf_cfg" in tm directory and use cat command to get info. It will return info to userspace, rather than record in dmesg.
The display style is below: $ cat qos_buf_cfg tx_packet_buf_tc_0: 0x120 tx_packet_buf_tc_1: 0x120 tx_packet_buf_tc_2: 0x120 tx_packet_buf_tc_3: 0x120 tx_packet_buf_tc_4: 0x0 tx_packet_buf_tc_5: 0x0 tx_packet_buf_tc_6: 0x0 tx_packet_buf_tc_7: 0x0 ......

Currently, user gets qset shaper parameters by implementing debugfs command "echo dump qs shaper > cmd", this command will dump info in dmesg. It's unnecessary and heavy.
As there is "tm_qset" file in tm directory for dump qset info, to optimize these command, merge qset shaper parameters to tm_qset file and use cat command to get them.
The display style is below: $ cat tm_qset ID MAP_PRI LINK_VLD MODE DWRR IR_B IR_U IR_S BS_B BS_S FLAG 0000 0 1 dwrr 100 150 7 0 5 20 0 0001 0 0 sp 0 150 7 0 5 20 0

----------------------------
Currently, the debugfs command for ncl config is implemented by "echo xxxx > cmd", and record the information in dmesg. It's unnecessary and heavy. To improve it, create a single file "mac_tbl" for it, and query it by command "cat mac_tbl", return the result to userspace, rather than record in dmesg.

----------------------------
Currently, the cmd index is obtained in debugfs by comparing file names. However, this method may cause errors when processing more complex file names. So, change this method by saving cmd in private data and comparing it when getting cmd index in debugfs for optimization.

---------------------------------------------------
This reverts commit 2eeca9dad888d02764d0366d573a659ffad7f825.
This patch adds support for extended VLAN mode, as we call dynamic vlan mode. In this mode, vf vlan filter will be switch between enable and disable, according to user configuration.
This patch also adds support for QOS in vlan 802.1Q protocol.

From: Jian Shen shenjian15@huawei.com
mainline inclusion from mainline-v5.14-rc1 commit 2ba306627f59 category: feature bugzilla: NA CVE: NA
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?i...
----------------------------------------------------------------------
Previously, with hardware limitation, the port VLAN filter are effective for both PF and its VFs simultaneously, so a single function is not able to enable/disable separately, and the VLAN filter state is default enabled. Now some device supports each function to bypass port VLAN filter, then each function can switch VLAN filter separately. Add capability flag to check whether the device supports modify VLAN filter state. If flag on, user will be able to modify the VLAN filter state by ethtool -K.
Furtherly, the default VLAN filter state is also changed according to whether non-zero VLAN used. Then the device can receive packet with any VLAN tag if only VLAN 0 used.
The function hclge_need_enable_vport_vlan_filter() is used to help implement above changes. And the VLAN filter handle for promisc mode can also be simplified by this function.

There are some features of VF depend on PF, so it's necessary for VF to know whether PF supports. For compatibility, modify the mailbox HCLGE_MBX_GET_TCINFO, extend its function, use to get the basic information of PF, including mailbox api version and PF capabilities.

----------------------------------------------------------------------
Previously, there is hardware limitation for VF to modify the VLAN filter state, and the VLAN filter state is default enabled. Now the limitation has been removed in some device, so add capability flag to check whether the device supports modify VLAN filter state. If flag on, user will be able to modify the VLAN filter state by ethtool -K. VF needs to send mailbox to request the PF to modify the VLAN filter state for it.

----------------------------------------------------------------------
Add debugfs support for vlan configuraion. create a single file "vlan_config" for it, and query it by command "cat vlan_config", return the result to userspace.
The new display style is below: $ cat vlan_config I_PORT_VLAN_FILTER: on E_PORT_VLAN_FILTER: off FUNC_ID I_VF_VLAN_FILTER E_VF_VLAN_FILTER PORT_VLAN_FILTER_BYPASS pf off on off vf0 off on off FUNC_ID PVID ACCEPT_TAG1 ACCEPT_TAG2 ACCEPT_UNTAG1 ACCEPT_UNTAG2 pf 0 on on on on vf0 0 on on on on

----------------------------------------------------------------------
Currently, the HNS3 driver only supports offload for tc number and prio_tc. This patch adds support for other qopts, including queues count and offset for each tc.
When enable tc mqprio offload, it's not allowed to change queue numbers by ethtool. For hardware limitation, the queue number of each tc should be power of 2.
For the queues is not assigned to each tc by average, so it's should return vport->alloc_tqps for hclge_get_max_channels().

HCLGE_FLAG_MQPRIO_ENABLE is supposed to set when enable multiple TCs with tc mqprio, and HCLGE_FLAG_DCB_ENABLE is supposed to set when enable multiple TCs with ets. But the driver mixed the flags when updating the tm configuration.
Furtherly, PFC should be available when HCLGE_FLAG_MQPRIO_ENABLE too, so remove the unnecessary limitation.

mainline inclusion from mainline-master commit 8c1671e0d13d category: bugfix bugzilla: NA CVE: NA

----------------------------------------------------------------------
Currently, when query PFC configuration by dcbtool, driver will return PFC enable status based on TC. As all priorities are mapped to TC0 by default, if TC0 is enabled, then all priorities mapped to TC0 will be shown as enabled status when query PFC setting, even though some priorities have never been set.
for example: $ dcb pfc show dev eth0 pfc-cap 4 macsec-bypass off delay 0 prio-pfc 0:off 1:off 2:off 3:off 4:off 5:off 6:off 7:off $ dcb pfc set dev eth0 prio-pfc 0:on 1:on 2:on 3:on $ dcb pfc show dev eth0 pfc-cap 4 macsec-bypass off delay 0 prio-pfc 0:on 1:on 2:on 3:on 4:on 5:on 6:on 7:on

A number of static variables were not modified. Make them const to allow the compiler to put them in read-only memory. In order to do so, constify a couple of input pointers as well as some local pointers. This moves about 35Kb to read-only memory as seen by the output of the size command.

----------------------------
Currently, in function hns3_nic_set_real_num_queue(), the driver doesn't report the queue count and offset for disabled tc. If user enables multiple TCs, but only maps user priorities to partial of them, it may cause the queue range of the unmapped TC being displayed abnormally.
Fix it by removing the tc enable checking, ensure the queue count is not zero.
With this change, the tc_en is useless now, so remove it.
