linux-toradex.git/include/net/devlink.h, branch v4.16-rc4 Linux kernel for Apalis and Colibri modules devlink: Add relation between dpipe and resource 2018-01-16T19:15:34+00:00 Arkadi Sharshevsky arkadis@mellanox.com 2018-01-15T07:59:05+00:00 56dc7cd0a87a1ff4f49ee1e67bd88e768385d51a The hardware processes which are modeled via dpipe commonly use some internal hardware resources. Such relation can improve the understanding of hardware limitations. The number of resource's unit consumed per table's entry are also provided for each table.

Each resource is identified via id, furthermore it contains information regarding its size and its related sub resources. Each resource can also provide its current occupancy. In some cases the sizes of some resources can be changed, yet for those changes to take place a hot driver reload may be needed. The reload capability will be introduced in the next patch.

Currently there are two global lock where one protects all devlink access, and the second one protects devlink port access. This patch adds per devlink instance lock which protects the internal members which are the sb/dpipe/ resource/ports. By introducing this lock the global devlink port lock can be discarded.
