      Revert "drm: drop redundant drm_file->is_master" · 7963e9db
      由 Dave Airlie 提交于 
      This reverts commit 48ba8137.

Thanks to Chris:
"drm_file->is_master is not synomous with having drm_file->master ==
drm_file->minor->master. This is because drm_file->master is the same
for all drm_files of the same generation and so when there is a master,
every drm_file believes itself to be the master. Confusion ensues and
things go pear shaped when one file is closed and there is no master
anymore."

      drm/tegra: Changes for v3.17-rc1

Mostly some cleanup all over the place. Pitch alignment limitations of
the display controller are now honored and job submission is 64-bit
safe.

The SOR output (used for eDP) properly configures sync signal polarities
according to the display mode rather than hard-coding them to some value
and the number of bits per color is now taken from the panel rather than
hard-coded to properly support 24-bit vs. 18-bit panels.

The DSI controller now properly supports non-continuous clock mode.

GEM objects can now have their flags and tiling mode modified via IOCTLs
to allow buffers imported from Nouveau to be properly displayed. Newer
generations of the Tegra display controller can also detile block linear
buffers at scan-out time.

Finally the driver now properly exports MODULE_DEVICE_TABLEs to allow it
to be automatically loaded when built as a module.

      drm/panel: Changes for v3.17-rc1

Panels can now be more finely controlled via .prepare() and .unprepare()
callbacks in addition to .enable() and .disable(). New kerneldoc details
what they are supposed to do and when they should be called.

The simple panel driver gained support for a couple of new panels and it
is now possible to specify additional delays during power up and power
down sequences if panels require it.

DSI devices can now advertise that they support non-continuous clock
mode which will allow DSI host controllers to disable the high speed
clock after transmissions to save power.

      drm/radeon: Prevent hdmi deep color if max_tmds_clock is undefined. · 9f51e2e0
      由 Mario Kleiner 提交于 
      HDMI spec requires a valid max_tmds_clock from edid for hdmi
deep color modes. If a sink violates this, disable deep color.

Also add a hint to user about the deep_color module parameter if
deep color is disabled due to that.

      drm: make sysfs device always available for minors · e1728075
      由 David Herrmann 提交于 
      For each minor we allocate a sysfs device as minor->kdev. Currently, this
is allocated and registered in drm_minor_register(). This makes it
impossible to add sysfs-attributes to the device before it is registered.
Therefore, they are not added atomically, nor can we move device_add()
*after* ->load() is called.

This patch makes minor->kdev available early, but only adds the device
during minor-registration. Note that the registration is still called
before ->load() as debugfs needs to be split, too. This will be fixed in
follow-ups.

      drm: make minor->index available early · f1b85962
      由 David Herrmann 提交于 
      Instead of allocating the minor-index during registration, we now do this
during allocation. This way, debug-messages between minor-allocation and
minor-registration will now use the correct minor instead of 0. Same is
done for unregistration vs. free, so debug-messages between
device-shutdown and device-destruction show proper indices.

Even though minor-indices are allocated early, we don't enable minor
lookup early. Instead, we keep the entry set to NULL and replace it during
registration / unregistration. This way, the index is allocated but lookup
only works if registered.

      drm: merge drm_drv.c into drm_ioctl.c · ec8f112d

      All that is left in drm_drv.c is ioctl management. Merge it into
drm_ioctl.c so we have all ioctl management in one file (and the name is
much more fitting).

Maybe we should now rename drm_stub.c to drm_drv.c again?

      drm: move module initialization to drm_stub.c · 1b7199fe
      由 David Herrmann 提交于 
      Most of the new DRM management functions are nowadays in drm_stub.c. By
moving the core module initialization to drm_stub.c we can make several
global variables static and keep the stub-open helper local.

The core files now look like this:
  drm_stub.c: Core management
   drm_drv.c: Ioctl dispatcher
 drm_ioctl.c: Actual ioctl backends
  drm_fops.c: Char-dev file-operations

A follow-up patch will move what is left from drm_drv.c into drm_ioctl.c.

      drm: don't de-authenticate clients on master-close · 3cb01a98
      由 David Herrmann 提交于 
      If an active DRM-Master closes its device, we deauthenticate all clients
on that master. However, if an inactive DRM-Master closes its device, we
do nothing. This is quite inconsistent and breaks several scenarios:

 1) If this was used as security mechanism, it fails horribly if a master
    closes a device while VT switched away. Furthermore, none of the few
    drivers using ->master_*() callbacks seems to require it, anyway.

 2) If you spawn weston (or any other non-UMS compositor) in background
    while another compositor is active, both will get assigned to the
    same "drm_master" object. If the foreground compositor now exits, all
    clients of both the foreground AND background compositor will be
    de-authenticated leading to unexpected behavior.

Stop this non-sense and keep clients authenticated. We don't do this when
dropping DRM-Master (i.e., switching VTs) so don't do it on active-close
either!

      drm: drop redundant drm_file->is_master · 48ba8137
      由 David Herrmann 提交于 
      The drm_file->is_master field is redundant as it's equivalent to:
    drm_file->master && drm_file->master == drm_file->minor->master

1) "=>"
  Whenever we set drm_file->is_master, we also set:
      drm_file->minor->master = drm_file->master;

  Whenever we clear drm_file->is_master, we also call:
      drm_master_put(&drm_file->minor->master);
  which implicitly clears it to NULL.

2) "<="
  minor->master cannot be set if it is non-NULL. Therefore, it stays as
  is unless a file drops it.

  If minor->master is NULL, it is only set by places that also adjust
  drm_file->is_master.

Therefore, we can safely drop is_master and replace it by an inline helper
that matches:
    drm_file->master && drm_file->master == drm_file->minor->master

      drm: extract legacy ctxbitmap flushing · 9f8d21ea
      由 David Herrmann 提交于 
      The ctxbitmap code is only used by legacy drivers so lets try to keep it
as separated as possible. Furthermore, the locking is non-obvious and
kinda weird with ctxlist_mutex *and* struct_mutex. Keeping all ctxbitmap
access in one file is much easier to review and makes drm_release() more
readable.

      drm/radeon: Use pflip irqs for pageflip completion if possible. (v2) · 39dc5454
      由 Mario Kleiner 提交于 
      Skip the "manual" pageflip completion checks via polling and
guessing in the vblank handler radeon_crtc_handle_vblank() on
asics which are known to reliably support hw pageflip completion
irqs. Those pflip irqs are a more reliable and race-free method
of handling pageflip completion detection, whereas the "classic"
polling method has some small races in combination with dpm on,
and with the reworked pageflip implementation since Linux 3.16.

On old asics without pflip irqs, the classic method is used.

On asics with known good pflip irqs, only pflip irqs are used
by default, but a new module parameter "use_pflipirqs" allows to
override this in case we encounter asics in the wild with
unreliable or faulty pflip irqs. A module parameter of 0 allows
to use the classic method only in such a case. A parameter of 1
allows to use both classic method and pflip irqs as additional
band-aid to avoid some small races which could happen with the
classic method alone. The setting 1 gives Linux 3.16 behaviour.

Hw pflip irqs are available since R600.

Tested on DCE-4, AMD Cedar - FirePro 2270.

v2:  agd5f: only enable pflip interrupts on DCE4+ as they are not
reliable on older asics.
