It introduces the for_each_gt() macro that loops over the tiles to perform per gt actions. This patch is a combination of two patches developed originally by Abdiel, who introduced some refactoring during probe, and then Tvrtko has added the necessary tools to start using the various tiles. The second patch re-organises the sysfs interface to expose the API for each of the GTs. I decided to prioritise this patch over others to unblock Sujaritha for further development. A third series will still follow this. Thanks Michal and Andrzej for the reviews and support! Thanks, Andi Patchwork: https://patchwork.freedesktop.org/series/98741/ Changelog ========= v5 -> v6 - address all Michal and Andrzej's reviews that consist mainly in code refactoring. v4 -> v5 - fixed Michal's reviews. - the sysfs patches have been split in 3 parts to make reviews easier. - Sujaritha's patch on pm throttle has been queued. - INTEL_REGION_LMEM has been renamed to INTEL_REGION_LMEM_0 - added the gt_is_root() helper - the sysfs files will be called intel_gt_sysfs_* instead of sysfs_gt_* v3 -> v4 - fixed Tvrtko's review: - remove the SYSFS_DEPRECATED_V2 mention from the commit log - reworded the error message when accessing deprecated files - errors in sysfs are printed as warnings as they are not fatal - the inline functions are moved to be out of line. and some other minor refactoring. v2 -> v3 - Added Matt and Sujaritha's r-b for patch 1 and 2. - Reworded the commit of patch 2 to underline the fact that the interface is useful also when used manually. v1 -> v2 - fixed a couple of coding style issues in patch 2.
