    drm/irq: Make pipe unsigned and name consistent

Triggering a warning when trying to sample the vblank timestamp for a
non-existing pipe. There's a few ways to fix this:

- Open-code the old behaviour, which just enshrines this slight
  breakage of the userspace ABI.

- Revert Mario's commit and again inflict broken timestamps, again not
  pretty.

- Fix this for real by delaying the pageflip TS until the next vblank
  interrupt, thereby making it accurate.

This patch implements the third option. Since having a page flip
interrupt that happens when the pageflip gets armed and not when it
completes in the next vblank seems to be fairly common (older i915 hw
works very similarly) create a new helper to arm vblank events for
such drivers.

v2 (Mario Kleiner):
- Fix function prototypes in drmP.h
- Add missing vblank_put() for pageflip completion without
  pageflip event.
- Initialize sequence number for queued pageflip event to avoid
  trouble in drm_handle_vblank_events().
- Remove dead code and spelling fix.

v3 (Mario Kleiner):
- Add a signed-off-by and cc stable tag per Ilja's advice.

v4 (Thierry Reding):
- Fix kerneldoc typo, discovered by Michel Dänzer
- Rearrange tags and changelog

      drm: Fix an unwanted master inheritance v2 · a0af2e53
      由 Thomas Hellstrom 提交于 
      A client calling drmSetMaster() using a file descriptor that was opened
when another client was master would inherit the latter client's master
object and all its authenticated clients.

This is unwanted behaviour, and when this happens, instead allocate a
brand new master object for the client calling drmSetMaster().

Fixes a BUG() throw in vmw_master_set().

      drm: Add DRM_DEBUG_VBL() · 235fabe0
      由 Ville Syrjälä 提交于 
      Add a new debug class for _verbose_ debug message from the vblank code.
That is message we spew out potentially for every vblank interrupt.
Thierry already got annoyed at the spew, and now I managed to lock up
my box with these debug prints (seems serial console + a few debug
prints every vblank aren't a good combination).

Or should I maybe call it DRM_DEBUG_IRQ?

      drm: Turn off Legacy Context Functions · 0e975980
      由 Peter Antoine 提交于 
      The context functions are not used by the i915 driver and should not
be used by modeset drivers. These driver functions contain several bugs
and security holes. This change makes these functions optional can be
turned on by a setting, they are turned off by default for modeset
driver with the exception of the nouvea driver that may require them with
an old version of libdrm.

      Add virtio gpu driver. · dc5698e8
      由 Dave Airlie 提交于 
      This patch adds a kms driver for the virtio gpu.  The xorg modesetting
driver can handle the device just fine, the framebuffer for fbcon is
there too.

Qemu patches for the host side are under review currently.

The pci version of the device comes in two variants: with and without
vga compatibility.  The former has a extra memory bar for the vga
framebuffer, the later is a pure virtio device.  The only concern for
this driver is that in the virtio-vga case we have to kick out the
firmware framebuffer.

Initial revision has only 2d support, 3d (virgl) support requires
some more work on the qemu side and will be added later.

      drm/vblank: Fixup and document timestamp update/read barriers · 99264a61
      由 Daniel Vetter 提交于 
      This was a bit too much cargo-culted, so lets make it solid:
- vblank->count doesn't need to be an atomic, writes are always done
  under the protection of dev->vblank_time_lock. Switch to an unsigned
  long instead and update comments. Note that atomic_read is just a
  normal read of a volatile variable, so no need to audit all the
  read-side access specifically.

- The barriers for the vblank counter seqlock weren't complete: The
  read-side was missing the first barrier between the counter read and
  the timestamp read, it only had a barrier between the ts and the
  counter read. We need both.

- Barriers weren't properly documented. Since barriers only work if
  you have them on boths sides of the transaction it's prudent to
  reference where the other side is. To avoid duplicating the
  write-side comment 3 times extract a little store_vblank() helper.
  In that helper also assert that we do indeed hold
  dev->vblank_time_lock, since in some cases the lock is acquired a
  few functions up in the callchain.

Spotted while reviewing a patch from Chris Wilson to add a fastpath to
the vblank_wait ioctl.

v2: Add comment to better explain how store_vblank works, suggested by
Chris.

v3: Peter noticed that as-is the 2nd smp_wmb is redundant with the
implicit barrier in the spin_unlock. But that can only be proven by
auditing all callers and my point in extracting this little helper was
to localize all the locking into just one place. Hence I think that
additional optimization is too risky.

      drm: Add DRM_DEBUG_ATOMIC · 17a38d9c
      由 Daniel Vetter 提交于 
      Atomic state handling adds a lot of indirection and complexity between
simple updates and drivers. For easier debugging the diagnostic output
is therefore rather chatty. Which is great for tracking down atomic
issues, but really annoying otherwise.

Add a new DRM_DEBUG_ATOMIC to be able to filter this out.

      drm/irq: Add drm_crtc_vblank_reset · 9625604c
      由 Daniel Vetter 提交于 
      At driver load we need to tell the vblank code about the state of the
pipes, so that the logic around reject vblank_get when the pipe is off
works correctly.

Thus far i915 used drm_vblank_off, but one of the side-effects of it
is that it also saves the vblank counter. And for that it calls down
into the ->get_vblank_counter hook. Which isn't really a good idea
when the pipe is off for a few reasons:
- With runtime pm the register might not respond.
- If the pipe is off some datastructures might not be around or
  unitialized.

The later is what blew up on gen3: We look at intel_crtc->config to
compute the vblank counter, and for a disabled pipe at boot-up that's
just not there. Thus far this was papered over by a check for
intel_crtc->active, but I want to get rid of that (since it's fairly
race, vblank hooks are called from all kinds of places).

So prep for that by adding a _reset functions which only does what we
really need to be done at driver load: Mark the vblank pipe as off,
but don't do any vblank counter saving or event flushing - neither of
that is required.

v2: Clarify the code flow slightly as suggested by Ville.

v3: Fix kerneldoc spelling, spotted by Laurent.

      drm: add atomic properties · 88a48e29
      由 Rob Clark 提交于 
      Once a driver is using atomic helpers for modeset, the next step is to
switch over to atomic properties.  To do this, make sure that any
modeset objects have their ->atomic_{get,set}_property() vfuncs suitably
populated if they have custom properties (you did already remember to
plug in atomic-helper func for the legacy ->set_property() vfuncs,
right?), and then set DRIVER_ATOMIC bit in driver_features flag.

A new cap is introduced, DRM_CLIENT_CAP_ATOMIC, for the purposes of
shielding legacy userspace from atomic properties.  Mostly for the
benefit of legacy DDX drivers that do silly things like getting/setting
each property at startup (since some of the new atomic properties will
be able to trigger modeset).
