drm/prime: Unconditionally set up the prime file private

2019-06-21T09:48:09+00:00

It's tiny, already embedded, and setup/teardown cost is trivial. Reviewed-by: Eric Anholt Reviewed-by: Emil Velikov Signed-off-by: Daniel Vetter Link: https://patchwork.freedesktop.org/patch/msgid/20190614203615.12639-5-daniel.vetter@ffwll.ch

drm: drop use of drmP.h in drm/*

2019-05-27T16:07:03+00:00

The use of the drmP.h header file is deprecated. Remove use from all files in drm/* so people do not look there and follow a bad example. Build tested allyesconfig,allmodconfig on x86, arm etc. Including alpha that is as always more challenging than the rest.

drm: Some ocd in drm_file.c

2019-05-09T09:40:20+00:00

Move the open helper around to avoid the forward decl, and give drm_setup a drm_legacy_ prefix since it's all legacy stuff in there. v2: Move drm_legacy_setup into drm_legacy_misc.c (Chris). The counterpart in the form of drm_legacy_dev_reinit is there already too, plus it fits perfectly into Dave's work of making DRIVER_LEGACY code compile-time optional.

drm/legacy: remove some legacy lock struct members

2019-04-24T02:36:32+00:00

This removes these unless legacy is enabled. The lock count init is unneeded anyways since it's kzalloc. Reviewed-by: Daniel Vetter Signed-off-by: Dave Airlie

drm: Wake up next in drm_read() chain if we are forced to putback the event

2019-02-27T22:04:54+00:00

After an event is sent, we try to copy it into the user buffer of the first waiter in drm_read() and if the user buffer doesn't have enough room we put it back onto the list. However, we didn't wake up any subsequent waiter, so that event may sit on the list until either a new vblank event is sent or a new waiter appears. Rare, but in the worst case may lead to a stuck process.

drm: Fix drm_release() and device unplug

2019-02-21T11:11:32+00:00

If userspace has open fd(s) when drm_dev_unplug() is run, it will result in drm_dev_unregister() being called twice. First in drm_dev_unplug() and then later in drm_release() through the call to drm_put_dev(). Since userspace already holds a ref on drm_device through the drm_minor, it's not necessary to add extra ref counting based on no open file handles. Instead just drm_dev_put() unconditionally in drm_dev_unplug(). We now have this: - Userpace holds a ref on drm_device as long as there's open fd(s) - The driver holds a ref on drm_device as long as it's bound to the struct device When both sides are done with drm_device, it is released.

drm: plug memory leak on drm_setup() failure

Currently we fail to free and detach the drm_file when drm_setup() fails. Use the drm_close_helper to do address that. Signed-off-by: Emil Velikov Reviewed-by: Daniel Vetter Link: https://patchwork.freedesktop.org/patch/msgid/20190114084410.15266-2-emil.l.velikov@gmail.com
