drm/i810: drop device_is_agp callback

2017-01-26T09:44:43Z

Use the same trick we used for i915 when we still had ums support: Just initialize the agp support unconditionally in the driver load function. Unfortunately that means we need to export drm_agp_init again, but I think that's a lesser evil.

drm: define drm_compat_ioctl NULL on CONFIG_COMPAT=n and reduce #ifdefs

2016-11-02T15:33:47Z

If we define drm_compat_ioctl NULL on CONFIG_COMPAT=n, we don't have to check for the config everywhere. Reviewed-by: Patrik Jakobsson Signed-off-by: Jani Nikula Signed-off-by: Sean Paul Link: http://patchwork.freedesktop.org/patch/msgid/1478014844-27454-1-git-send-email-jani.nikula@intel.com

drm: Move drm_memory.c map support declarations to

2014-09-12T13:28:12Z

And replace the drm_core_ prefix with drm_legacy_ since really, this isn't core stuff. Also drop drm_core_dropmap since it's unused. v2: Fix up i810.ko fully which somehow slipped through. Signed-off-by: Daniel Vetter

drm: move drm-lock API to drm_legacy.h

2014-09-10T07:43:34Z

Same as the other legacy APIs, most of this is internal, so prefix it with drm_legacy_* and move into drm_legacy.h. Signed-off-by: David Herrmann Reviewed-by: Thierry Reding Signed-off-by: Dave Airlie

drm: Remove DRM_ARRAY_SIZE() for ARRAY_SIZE()

2014-06-09T23:36:17Z

I cannot see a need to provide a DRM_ version of ARRAY_SIZE(), only used in a few places. I suspect its usage has been spread by copy & paste rather than anything else. Let's just remove it for plain ARRAY_SIZE(). Signed-off-by: Damien Lespiau Reviewed-by: Alex Deucher Signed-off-by: Dave Airlie

drm: kill DRIVER_REQUIRE_AGP

2013-12-18T01:17:53Z

Only the two intel drivers need this and they can easily check for working agp support in their driver ->load callbacks. This is the only reason why agp initialization could fail, so allows us to rip out a bit of error handling code in the next patch. Signed-off-by: Daniel Vetter Signed-off-by: Dave Airlie

drm: remove FASYNC support

2013-08-19T00:05:17Z

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 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.
