From 6814dbf9414818861cdc21ba1f9799eb2e339b07 Mon Sep 17 00:00:00 2001 From: Rob Clark Date: Sat, 9 Aug 2014 09:07:25 -0400 Subject: [PATCH] drm/msm: avoid flood of kernel logs on faults 87e956e9 changed the fault handler to return -ENOSYS, which causes the iommu driver to print out a huge splat. Which wouldn't be quite so bad if nothing ever faulted. But seems like some EXA composite operations generate quite a lot of (seemingly harmless) faults. That is probably a userspace problem, but the huge increase in verbosity from iommu fault dumps makes things kind of unusable. We probably should actually log *some* message (not conditional on drm.debug). But ratelimit it. Signed-off-by: Rob Clark --- Reading git-format-patch failed
