[PATCH 1/3] drm: Stop spamming log with drm_cache message

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

 



Only x86 and in some cases PPC have support added in drm_cache.c for the
clflush class of functions. However warning once is sufficient to taint
the log instead of spamming it with "Architecture has no drm_cache.c
support" every few millisecond.
