2019-01-29drm/irq: Ditch DRIVER_IRQ_SHAREDDaniel Vetter1-2/+1
This is only used by drm_irq_install(), which is an optional helper. For legacy pci devices this is required (due to interrupt sharing without msi/msi-x), and just making this the default exactly matches the behaviour of all existing drivers using the drm_irq_install() helpers. In case that ever becomes wrong drivers can roll their own irq handling, as many drivers already do (for other reasons like needing a threaded interrupt handler, or having an entire pile of different interrupt sources). v2: Rebase v3: Improve commit message (Emil) Cc: Sam Ravnborg <sam@ravnborg.org> Reviewed-by: Emil Velikov <emil.velikov@collabora.com> Signed-off-by: Daniel Vetter <daniel.vetter@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20190129104248.26607-3-daniel.vetter@ffwll.ch

If a non-legacy driver calls these it's valid to assume there is interrupt support. The flag is really only needed for legacy drivers, which control IRQ enabling/disabling through the DRM_IOCTL_CONTROL legacy IOCTL.

This was added in commit 0a3e67a4caac273a3bfc4ced3da364830b1ab241 Author: Jesse Barnes <jbarnes@virtuousgeek.org> Date: Tue Sep 30 12:14:26 2008 -0700 drm: Rework vblank-wait handling to allow interrupt reduction. to stay backwards-compatible with old UMS code that didn't even tell the kernel when it did a modeset, so that the kernel could save/restore vblank counters. At worst this means vblanks will be somewhat funky on a setup that very likely no one still runs. So let's just nuke it. Plan B would be to set it unconditionally in drm_vblank_init for kms drivers, instead of in each driver separately. So if this patch breaks anything please only restore the hunks in drmP.h and drm_irq.c, plus add a check for DRIVER_MODESET in drm_vblank_init. Stumbled over this in a discussion on irc with Chris.

Nouveau is the only driver that uses two different bus-types with the same drm_driver. This is totally broken if both buses are available on the same machine (unlikely, but lets be safe).

All drivers embed gem-objects into their own buffer objects. There is no reason to keep drm_gem_object_alloc(), gem->driver_private and ->gem_init_object() anymore. New drivers are highly encouraged to do the same. There is no benefit in allocating gem-objects separately.

2013-08-19drm: rip out a few unused DRIVER flagsDaniel Vetter1-1/+1
The gma500 driver somehow set the DRIVER_IRQ_VBL flag, but since there's no code at all to check for this we can kill it. The other two are completely unused. Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch> Signed-off-by: Dave Airlie <airlied@redhat.com>
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.

2013-01-20drm/gma500: use drm_modeset_lock_allDaniel Vetter1-4/+4
Only two places: - suspend/resume - Some really strange mode validation tool with too much funny-lucking hand-rolled conversion code. - The recently-added lastclose fbdev restore code. Better safe than sorry, so convert both places to keep the locking semantics as much as possible. Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>
2013-01-20drm/gma500: move fbcon restore to lastcloseDaniel Vetter1-0/+10
Doing this within the fb->destroy callback leads to a locking nightmare. And all other drm drivers that restore the fbcon do it in lastclose, too. With this adjustments all fb->destroy callbacks optionally drop references to any gem objects used as backing storage, call drm_framebuffer_cleanup and then kfree the struct. Which nicely simplifies the locking for framebuffer unreferencing and freeing, since this doesn't require that we hold the mode_config lock. A slight exception is the vmwgfx surface backed framebuffer, it also calls drm_master_put and removes the object from a device-private framebuffer list. Both seem to have solid locking in place already. Conclusion is that now it is no longer required to hold the mode_config lock while freeing a framebuffer. v2: Drop the corresponding mutex_lock WARN check from drm_framebuffer_unreference. v3: Use just the mode_config lock not modeset_lock_all, due to patch reordering.
