gpu: drm: amd/radeon: Convert printk(KERN_ to pr_

2017-03-30T03:53:24Z

Use a more common logging style. Miscellanea: o Coalesce formats and realign arguments o Neaten a few macros now using pr_ Signed-off-by: Joe Perches Signed-off-by: Alex Deucher

drm/radeon: fix indentation.

2016-03-16T22:08:06Z

I hate doing this but it hurts my eyes to go over code that does not comply with indentation rules. Only thing that is not only space change is in atom.c all other files are space indentation issues.

drm/radeon: add locking around atombios scratch space usage

2014-11-11T22:22:26Z

While developing MST support I noticed I often got the wrong data back from a transaction, in a racy fashion. I noticed the scratch space wasn't locked against concurrent users. Based on a patch by Alex, but I've made it a bit more obvious when things are locked. Signed-off-by: Dave Airlie Signed-off-by: Alex Deucher Cc: stable@vger.kernel.org

drm/radeon/atom: initialize more atom interpretor elements to 0

2013-07-30T21:24:12Z

The ProcessAuxChannel table on some rv635 boards assumes the divmul members are initialized to 0 otherwise we get an invalid fb offset since it has a bad mask set when setting the fb base. While here initialize all the atom interpretor elements to 0. Fixes: https://bugzilla.kernel.org/show_bug.cgi?id=60639 Signed-off-by: Alex Deucher Cc: stable@vger.kernel.org

drm/radeon: Avoid NULL pointer dereference from atom_index_iio() allocation failure

2013-02-20T13:51:19Z

Smatch anlysis: drivers/gpu/drm/radeon/atom.c:1242 atom_index_iio() error: potential null dereference 'ctx->iio'. (kzalloc returns null) Also cleaned up some checks before calls to kfree(). kfree(NULL) is OK.

drm: introduce drm_can_sleep and use in intel/radeon drivers. (v2)

2012-01-06T10:01:35Z

So we have a few places where the drm drivers would like to sleep to be nice to the system, mainly in the modesetting paths, but we also have two cases were atomic modesetting must take place, panic writing and kernel debugger. So provide a central inline to determine if a sleep or delay should be used and use this in the intel and radeon drivers. v2: drop intel_drv.h MSLEEP macro, nobody uses it.

drm/radeon/kms/atom: fix handling of FB scratch indices

2011-10-19T08:47:47Z

FB scratch indices are dword indices, but we were treating them as byte indices. As such, we were getting the wrong FB scratch data for non-0 indices. Fix the indices and guard the indexing against indices larger than the scratch allocation. Fixes memory corruption on some boards if data was written past the end of the FB scratch array.
