drm: Move drm_vm_open_locked into drm_internal.h

2014-09-24T01:43:20+00:00

Leftover from my previous header cleanup. This depends upon the patch to rework exynos mmap support, otherwise it'll break exynos. Signed-off-by: Daniel Vetter Reviewed-by: David Herrmann Acked-by: Alex Deucher Signed-off-by: Dave Airlie

drm: move drm_mmap to

2014-09-24T01:43:07+00:00

Now that we've removed the copypasted users in gem/ttm we can relegate the legacy buffer mapping support to where it belongs. Also give it the proper drm_legacy_ prefix. While at it statify drm_mmap_locked, somehow I've missed that in my previous header rework. Signed-off-by: Daniel Vetter Reviewed-by: David Herrmann Acked-by: Alex Deucher Signed-off-by: Dave Airlie

drm: powerpc can use a simpler drm_io_prot()

2014-09-23T04:35:53+00:00

What the code does is equivalent to the x86 code, so let's use it as well Signed-off-by: Benjamin Herrenschmidt Signed-off-by: Dave Airlie

drm: Move __drm_pci_free to drm_legacy.h

2014-09-12T09:08:56+00:00

Also sprinkle the customary legacy_ prefix. Unfortunately we can't move the other functions since i915 is still using them. Shame on me for that one :( v2: Fix patch subject as spotted by David Herrmann. Signed-off-by: Daniel Vetter

drm: drop DRM_DEBUG_CODE

2014-09-10T07:41:20+00:00

DRM_DEBUG_CODE is currently always set, so distributions enable it. The only reason to keep support in code is if developers wanted to disable debug support. Sounds unlikely. All the DRM_DEBUG() printks are still guarded by a drm_debug read. So if its cacheline is read once, they're discarded pretty fast.. There should hardly be any performance penalty, it's even guarded by unlikely(). Signed-off-by: David Herrmann Reviewed-by: Thierry Reding Signed-off-by: Dave Airlie

drm: replace weird conditional includes

2014-09-10T07:40:35+00:00

pte_wrprotect() is only used by drm_vm.c, so move the include there. Also include it unconditionally, all architectures provide this header! Furthermore, replace asm/current.h with sched.h, which includes asm/current.h unconditionally. This way we get the same effect and avoid direct asm/ includes. Furthermore, drop the weird __alpha__ protection. It's safe to include sched.h everywhere (and the wait.h comment doesn't apply, anyway).

drm: move AGP definitions harder

2014-09-10T07:40:11+00:00

Move drm_agp_head to drm_agpsupport.h and drm_agp_mem into drm_legacy.h. Unfortunately, drivers still heavily access drm_agp_head so we cannot move it to drm_legacy.h. However, at least it's no longer visible in drmP.h now (it's directly included from it, though). Signed-off-by: David Herrmann Reviewed-by: Thierry Reding Signed-off-by: Dave Airlie

drm: move "struct drm_vma_entry" to drm_vm.c

2014-09-10T07:13:36+00:00

Make all the drm_vma_entry handling local to drm_vm.c and hide it from global headers. This requires to extract the inlined legacy drm_vma_entry cleanup into a small helper and also move a weirdly placed drm_vma_info helper into drm_vm.c.

drm: remove dev->vma_count

2013-12-18T01:43:29+00:00

This is just used for a debugfs file, and we can easily reconstruct this number by just walking the list twice. Which isn't really bad for a debugfs file anyway. So let's rip this out. There's the other issue that the dev->vmalist itself is a bit useless, since that can be reconstructed with all the memory mapping information from proc. But remove that is a different topic entirely. Signed-off-by: Daniel Vetter Signed-off-by: Dave Airlie

drm: rip out drm_core_has_AGP

2013-12-18T01:20:04+00:00

Most place actually want to just check for dev->agp (most do, but a few don't so this fixes a few potential NULL derefs). The only exception is the agp init code which should check for the AGP driver feature flag. Signed-off-by: Daniel Vetter Signed-off-by: Dave Airlie
