[CI,0/4] drm/i915: GSC FW support for MTL

Message

Daniele Ceraolo Spurio June 12, 2023, 6:15 p.m. UTC

Last chunk of the required support for the GSC FW. This includes some
fixes to the GSC memory allocation, FW idefinition and version
management, plus a new debugfs for debug information.

The FW team has asked to not send the current FW blob to
linux-firmware yet, as they're planning some updates. Therefore, the
FW definition patch will be sent separately and merged to the
topic/core-for-CI branch.
The series has already been tested with the FW definition patch applied
(see CI results on previous rev), so this is a re-send for CI to make
sure everything works without that patch before merging.

Daniele Ceraolo Spurio (4):
  drm/i915/gsc: fixes and updates for GSC memory allocation
  drm/i915/mtl/gsc: extract release and security versions from the gsc
    binary
  drm/i915/mtl/gsc: query the GSC FW for its compatibility version
  drm/i915/mtl/gsc: Add a gsc_info debugfs
