[Intel-gfx] [PATCH 6/7] drm/i915/guc: Make GuC log sizes runtime configurable
John.C.Harrison at Intel.com
John.C.Harrison at Intel.com
Thu Jul 28 02:20:27 UTC 2022
From: John Harrison <John.C.Harrison at Intel.com>
The GuC log buffer sizes had to be configured statically at compile
time. This can be quite troublesome when needing to get larger logs
out of a released driver. So re-organise the code to allow a boot time
module parameter override.
