2014-04-01drm: Replace crtc fb with primary plane fb (v3)Matt Roper1-7/+7
Now that CRTC's have a primary plane, there's no need to track the framebuffer in the CRTC. Replace all references to the CRTC fb with the primary plane's fb. This patch was generated by the Coccinelle semantic patching tool using the following rules: @@ struct drm_crtc C; @@ - (C).fb + C.primary->fb @@ struct drm_crtc *C; @@ - (C)->fb + C->primary->fb v3: Generate patch via coccinelle. Actual removal of crtc->fb has been moved to a subsequent patch. v2: Fixup several lingering crtc->fb instances that were missed in the first patch iteration.

The clk_prepare_enable() call can fail. Check it's return value. We can't propagate it all the way to the user as the KMS operations in which the clock is enabled return a void.

2013-10-11drm: Add separate Kconfig option for fbdev helpersDaniel Vetter1-0/+1
For drivers which might want to disable fbdev legacy support. Select the new option in all drivers for now, so this shouldn't result in any change. Drivers need some work anyway to make fbdev support optional (if they have it implemented, that is), so the recommended way to expose this is by adding per-driver options. At least as long as most drivers don't support disabling the fbdev support. v2: Update for new drm drivers msm and rcar-du. Note that Rob's msm driver can already take advantage of this, which allows us to build msm without any fbdev depencies in the kernel! v3: Move the MODULE_* stuff from the fbdev helper file to drm_crtc_helper.c.

2013-08-19drm: remove FASYNC supportDaniel Vetter1-1/+0
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 Vetter1-1/+1
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.

2013-04-26drm/shmobile: Fix race condition between page flip request and handlerLaurent Pinchart1-1/+1
The page flip handler stores the page flip event pointer and then calls drm_vblank_get() to enable the vblank interrupt. Due to the vblank off delay, the vblank interrupt can be enabled in the hardware at that point, even if the vblank reference count is equal to 0. If a vblank interrupt is triggered between storing the event pointer and calling drm_vblank_get(), the page flip completion handler will process the event and call drm_vblank_put() with a reference count equal to 0. This will result in a BUG_ON. Fix the race condition by calling drm_vblank_get() before storing the event pointer.
