[RFCv7 PATCH net-next 00/36] net: extend the type of netdev_features_t to bitmap
by Jian Shen 12 Aug '22

12 Aug '22

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. [patch 1] 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. Serveal macroes remained temporarily by some precompile dependency.[patch 36] The features group macroes in netdev_features.h are replaced by a set of const features defined in netdev_features.c. [patch 2-3] For example: macro NETIF_F_ALL_TSO is replaced by netdev_all_tso_features There are some drivers(e.g. sfc) use netdev_features in global structure initialization. Changed the its netdev_features_t memeber to netdev_features_t *, and make it prefer to a netdev_features_t global variables. [patch 4~9] Also, there are many features(e.g. NETIF_F_CSUM_MASK | NETIF_F_GSO_MASK) are used by several drivers, replaces them with global netdev features variables, in order to simple the expressions.[patch 10~13] As suggestion from Andrew Lunn, I wrote some semantic patches to do the work(replacing the netdev features operator by helpers). To make the semantic patches simple, I split the complex expressions of netdev_features to simple logical operation. [patch 14~15] For the prototype of netdev_features_t is no longer u64, so it's incorrect to assigne 0 to it, use netdev_empty_features intead. [patch 16] Some drivers defines macroes and functions wich use NETIF_F_XXX as parameter. For all the macroes NETIF_F_XXX will be removed at last, so change these macroes and functions to use NETIF_F_XXX_BIT. [patch 17~23] With above preparation, then apply the semantic patches to do the expression transition. For example, replace expression "ndev->hw_features |= NETIF_F_TSO;" by "netdev_hw_feature_set(ndev, NETIF_F_TSO_BIT)". [patch 24~35] With the prototype is no longer u64, the implementation of print interface for netdev features(%pNF) is changed to bitmap. [patch 36] I removed the netdev_features_copy and netdev_xxx_features() helpers in this patchset. It make the expressions being more complex. For example, expression "dev->features = dev->hw_features", it's too ugly to use "netdev_active_features_copy(dev, netdev_hw_features(hw))". I will try to find better way for this, avoiding the nic drivers to modify netdev_features directly. The former discussion please see [1][2][3][4][5].

[RFCv7 PATCH net-next 00/36] net: extend the type of netdev_features_t to bitmap
by Jian Shen 09 Aug '22

09 Aug '22

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. [patch 1] 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. Serveal macroes remained temporarily by some precompile dependency.[patch 36] The features group macroes in netdev_features.h are replaced by a set of const features defined in netdev_features.c. [patch 2-3] For example: macro NETIF_F_ALL_TSO is replaced by netdev_all_tso_features There are some drivers(e.g. sfc) use netdev_features in global structure initialization. Changed the its netdev_features_t memeber to netdev_features_t *, and make it prefer to a netdev_features_t global variables. [patch 4~9] Also, there are many feature group(e.g. NETIF_F_CSUM_MASK | NETIF_F_GSO_MASK) are used by several drivers, replaces them with global netdev features variables, in order to simple the expressions.[patch 10~13] As suggestion from Andrew Lunn, I wrote some semantic patches to do the work(replacing the netdev features operator by helpers). To make the semantic patches simple, I split the complex expressions of netdev_features to simple logical operation. [patch 14~15] For the prototype of netdev_features_t is no longer u64, so it's incorrect to assigne 0 to it, use netdev_empty_features intead. [patch 16] Some drivers defines macroes and functions wich use NETIF_F_XXX as parameter. For all the macroes NETIF_F_XXX will be removed at last, so change these macroes and functions to use NETIF_F_XXX_BIT. [patch 17~23] With above preparation, then apply the semantic patches to do the expression transition. For example, replace expression "ndev->hw_features |= NETIF_F_TSO;" by "netdev_hw_feature_set(ndev, NETIF_F_TSO_BIT)". [patch 24~35] With the prototype is no longer u64, the implementation of print interface for netdev features(%pNF) is changed to bitmap. [patch 36] I removed the netdev_features_copy and netdev_xxx_features() helpers in this patchset. It make the expressions being more complex. For example, expression "dev->features = dev->hw_features", it's too ugly to use "netdev_active_features_copy(dev, netdev_hw_features(hw))". I will try to find better way for this, avoiding the nic drivers to modify netdev_features directly. The former discussion please see [1][2][3][4][5].

Complete the treewide netdev features changes. Suggestions from Alexander Lobakin: refine the definition of DECLARE_NETDEV_FEATURE_SET, and remove useless blank lines. V5-V6: suggestions from Jakub Kicinski: drop the rename for netdev->features simplify names of some helpers, and move them to a new header file refine the implement for netdev_features_set_array

Hello
by JENNY MALTY 07 Aug '22

07 Aug '22

Hello , I’m Jenny, a research assistant of the Research and Development Department working at one of the leading Bio Pharmaceutical Companies here in England. I'm looking for a reliable person in your region to represent my company in sourcing some of our basic raw materials used in the manufacturing of high quality anti-viral vaccines, cancer treatment and other lifesaving pharmaceutical products. This may not be your area of specialization but it will be another income generating business out of your specialty. This is because our company is yet to locate any seller to buy from, however, I have been able to discover a local dealer who can supply us with this product. He is selling at a cheap rate, which is far cheaper than our previous purchases. I will give you more specific profit details when I receive feedback from you, if you are interested.

Business Expectations!
by Lewis Anderson 04 Aug '22

We're an Investment Group that recognize the impact and the challenges the covid19 pandemic has had on both corporate and SME enterprises, and therefore have developed programs and investor engagements that would not only help identify these gaps but also manage and create better business expectations. We have opportunities to attract viable investments to your business through our pool of financial investors, and for a chance to be considered for funding, kindly provide us your project brief or an executive summary for our review at my below email address. We look forward to hearing from you soon. Yours Sincerely, Lewis Anderson Client Project Manager | CPM

Zwiększenie płynności finansowej
by Jakub Olejniczak 01 Aug '22

Dzień dobry, kontaktuję się z Państwem, ponieważ chciałbym zaproponować wygodne rozwiązanie, które umożliwi Państwa firmie stabilny rozwój. Konkurencyjne otoczenie wymaga ciągłego ulepszania i poszerzenia oferty, co z kolei wiąże się z koniecznością inwestowania. Brak odpowiedniego kapitału poważnie ogranicza tempo rozwoju firmy. Od wielu lat z powodzeniem pomagam firmom w uzyskaniu najlepszej formy finansowania z banku oraz UE. Mam stałych Klientów, którzy nadal chętnie korzystają z moich usług, a także polecają je innym. Czy chcieliby Państwo skorzystać z pomocy wykwalifikowanego i doświadczonego doradcy finansowego? Pozdrawiam Jakub Olejniczak
