2016-07-18drm/shmobile: make fbdev support really optionalTobias Jakobi
Currently enabling SH Mobile DRM support automatically pulls in fbdev dependency. However this dep is unnecessary since DRM core already handles this for us (DRM_FBDEV_EMULATION).

2016-06-21drm: Lobotomize set_busid nonsense for !pci driversDaniel Vetter
We already have a fallback in place to fill out the unique from dev->unique, which is set to something reasonable in drm_dev_alloc. Which means we only need to have a special set_busid for pci devices, to be able to care the backwards compat code for drm 1.1 around, which libdrm still needs. While developing and testing this patch things blew up in really interesting ways, and the code is rather confusing in naming things between the kernel code, ioctl #defines and libdrm. For the next brave dragon slayer, document all this madness properly in the userspace interface section of gpu.tmpl. v2: Make drm_dev_set_unique static and update kerneldoc. v3: Entire rewrite, plus document what's going on for posterity in the gpu docbook uapi section. v4: Drop accidental amdgpu hunk (Emil). v5: Drop accidental omapdrm vblank counter change (Emil). v6: Rebase on top of the sphinx conversion.

2016-01-13drm: Do not set connector->encoder in driversThierry Reding
An encoder is associated with a connector by the DRM core as a result of setting up a configuration. Drivers using the atomic or legacy helpers should never set up this link, even if it is a static one. While at it, try to catch this kind of error in the future by adding a WARN_ON() in drm_mode_connector_attach_encoder(). Note that this doesn't cover all the cases, since drivers could set this up after attaching. Drivers that use the atomic helpers will get a warning later on, though, so hopefully the two combined cover enough to help people avoid this in the future.

2015-01-31drm: shmobile: fix Kconfig dependenciesArnd Bergmann
The shmobile drm driver selects BACKLIGHT_CLASS_DEVICE as of 0a5a5499ad88 "drm: shmobile: Add dependency on BACKLIGHT_CLASS_DEVICE", but that option in turn depends on BACKLIGHT_LCD_SUPPORT, so we actually have to select both, or alternatively use 'depends on BACKLIGHT_CLASS_DEVICE'. Further, the driver uses FB_SH_MOBILE_MERAM if that is enabled, but this breaks if MERAM is a module while the DRM driver is built-in. To solve this, add a dependency on "FB_SH_MOBILE_MERAM || !FB_SH_MOBILE_MERAM", which forces DRM_SHMOBILE to be a module if FB_SH_MOBILE_MERAM set to 'm'.

2013-10-11drm: Add separate Kconfig option for fbdev helpersDaniel Vetter
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 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.

2013-04-26drm/shmobile: Fix race condition between page flip request and handlerLaurent Pinchart
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.
