2014-08-15drm/radeon: add bapm module parameterAlex Deucher
Add a module paramter to enable bapm on APUs. It's disabled by default on certain APUs due to stability issues. This option makes it easier to test and to enable it on systems that are stable. bug: https://bugzilla.kernel.org/show_bug.cgi?id=81021 Signed-off-by: Alex Deucher <alexander.deucher@amd.com> Cc: stable@vger.kernel.org

2014-08-05drm/radeon: Use pflip irqs for pageflip completion if possible. (v2)Mario Kleiner
Skip the "manual" pageflip completion checks via polling and guessing in the vblank handler radeon_crtc_handle_vblank() on asics which are known to reliably support hw pageflip completion irqs. Those pflip irqs are a more reliable and race-free method of handling pageflip completion detection, whereas the "classic" polling method has some small races in combination with dpm on, and with the reworked pageflip implementation since Linux 3.16. On old asics without pflip irqs, the classic method is used. On asics with known good pflip irqs, only pflip irqs are used by default, but a new module parameter "use_pflipirqs" allows to override this in case we encounter asics in the wild with unreliable or faulty pflip irqs. A module parameter of 0 allows to use the classic method only in such a case. A parameter of 1 allows to use both classic method and pflip irqs as additional band-aid to avoid some small races which could happen with the classic method alone. The setting 1 gives Linux 3.16 behaviour. Hw pflip irqs are available since R600. Tested on DCE-4, AMD Cedar - FirePro 2270. v2: agd5f: only enable pflip interrupts on DCE4+ as they are not reliable on older asics.

Since this is a testing-only feature it should ever hurt, but I figured it'll help with regression-testing -fixes. So I left it in and didn't postpone it to 3.14. - Display power well refactoring from Imre. Would have caused major pain conflict with the bdw stage 1 patches if I'd postpone this to -next. It's only an relatively small interface rework, so shouldn't cause pain. It's also been in my tree since almost 3 weeks already. That accounts for about two thirds of the pull, otherwise just bugfixes: - vlv backlight fix from Jesse/Jani - vlv vblank timestamp fix from Jesse - improved edp detection through vbt from Ville (fixes a vlv issue) - eDP vdd fix from Paulo - fixes for dvo lvds on i830M - a few smaller things all over Note: This contains a backmerge of v3.12. Since the -internal branch always applied on top of -nightly I need that unified base to merge bdw patches. So you'll get a conflict with radeon connector props when pulling this (and nouveau/master will also conflict a bit when Ben doesn't rebase). The backmerge itself only had conflicts in drm/i915.

The new arch_phys_wc_add/del functions do the right thing both with and without MTRR support in the kernel. So we can drop these additional checks. David Herrmann suggest to also kill the DRIVER_USE_MTRR flag since it's now unused, which spurred me to do a bit a better audit of the affected drivers. David helped a lot in that.

So for real KMS drivers it's the drives responsibility to add an mtrr if it needs one. nouvea, radeon, mgag200, i915 and vmwgfx do that already. Somehow the savage driver also ends up doing that, I have no idea why. Note that gma500 as a pure KMS driver doesn't need MTRR setup since the platforms that it supports all support PAT. So no MTRRs needed to get wc iomappings. The mtrr support in the drm core is all for legacy mappings of garts, framebuffers and registers. All legacy drivers set the USE_MTRR flag, so we're good there. All in all I think we can really just ditch this /endquote v2: Also kill DRIVER_USE_MTRR as suggested by David Herrmann v3: Rebase on top of David Herrmann's agp setup/cleanup changes.

2013-08-19drm: remove FASYNC supportDaniel Vetter
So I've stumbled over drm_fasync and wondered what it does. Digging that up is quite a story. First I've had to read up on what this does and ended up being rather bewildered why peopled loved signals so much back in the days that they've created SIGIO just for that ... Then I wondered how this ever works, and what that strange "No-op." comment right above it should mean. After all calling the core fasync helper is pretty obviously not a noop. After reading through the kernels FASYNC implementation I've noticed that signals are only sent out to the processes attached with FASYNC by calling kill_fasync. No merged drm driver has ever done that. After more digging I've found out that the only driver that ever used this is the so called GAMMA driver. I've frankly never heard of such a gpu brand ever before. Now FASYNC seems to not have been the only bad thing with that driver, since Dave Airlie removed it from the drm driver with prejudice: commit 1430163b4bbf7b00367ea1066c1c5fe85dbeefed Author: Dave Airlie <airlied@linux.ie> Date: Sun Aug 29 12:04:35 2004 +0000 Drop GAMMA DRM from a great height ... Long story short, the drm fasync support seems to be doing absolutely nothing. And the only user of it was never merged into the upstream kernel. And we don't need any fops->fasync callback since the fcntl implementation in the kernel already implements the noop case correctly. So stop this particular cargo-cult and rip it all out. v2: Kill drm_fasync assignments in rcar (newly added) and imx drivers (somehow I've missed that one in staging). Also drop the reference in the drm DocBook. ARM compile-fail reported by Rob Clark. v3: Move the removal of dev->buf_asnyc assignment in drm_setup to this patch here. v4: Actually git add ... tsk.

2013-08-07drm/gem: create drm_gem_dumb_destroyDaniel Vetter
All the gem based kms drivers really want the same function to destroy a dumb framebuffer backing storage object. So give it to them and roll it out in all drivers. This still leaves the option open for kms drivers which don't use GEM for backing storage, but it does decently simplify matters for gem drivers.
