[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].

[RFCv6 PATCH net-next 00/19] net: extend the type of netdev_features_t to bitmap
by Jian Shen 21 Jul '22

21 Jul '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. As the nic drivers are not supposed to modify netdev_features directly, it also introduces wrappers helpers to this. [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. [patch 19] 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] As suggestion from Andrew Lunn, I wrote some semantic patches to do the work(replacing the netdev features operator by helpers). [patch 7-18] To make the semantic patches simple, I split the complex opreation of netdev_features to simple logical operation. [patch 5, 6] With the prototype is no longer u64, the implementation of print interface for netdev features(%pNF) is changed to bitmap. [patch 19] The whole work is not complete yet. I just use these changes on several files(hns3 driver, sfc drivers, net/ethtool, net/core/dev.c), in order to show how these helpers will be used. I will apply these helpers to the whole tree later, sofar I want to get more suggestions for this scheme, any comments would be appreciated. The former discussion please see [1][2][3][4].
