Subject: [PATCH v2 0/7] Refactor smu feature bit implementation
Date: Tue, 20 Jan 2026 11:42:17 +0530	[thread overview]
Message-ID: <20260120061402.1287680-1-lijo.lazar@amd.com> (raw)

Presently a 64-bit bitmask is used to represent the PM features enabled/supported by SOC. The
number of features has grown to nearly 64 and could extend beyond that. Instead of using a 64-bit
mask, implement a data structure around bitmap and move the implementation to use the datastructure
instead of directly operating on 64-bit bitmask.

v2:
 Use to_arr32 instead of direct assignment

Lijo Lazar (7):
  drm/amd/pm: Add smu feature bits data struct
  drm/amd/pm: Add smu feature interface functions
  drm/amd/pm: Remove unused logic in SMUv14.0.2
  drm/amd/pm: Initialize allowed feature list
  drm/amd/pm: Use feature bits data structure
  drm/amd/pm: Change get_enabled_mask signature
  drm/amd/pm: Add default feature number definition
