[PATCH v2 4/6] drm/i915/guc: More debug print updates - GuC selftests

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 

From: John Harrison <John.C.Harrison@xxxxxxxxx>

Update a bunch more debug prints to use the new GT based scheme.

v2: Also change prints to use %pe for error values (MichalW).
Fix a context leak on error due to a -- being too early.
Use the correct header file for the debug macros.

Signed-off-by: John Harrison <John.C.Harrison@xxxxxxxxx>
