Merge branch 'primary-plane' of git://people.freedesktop.org/~robclark/linux into drm-next

Here's the latest iteration of the universal planes work, which I believe is
finally ready for merging.  Aside from the minor driver patches to use the
new drm_for_each_legacy_plane() macro for plane loops, these should all have

drm/crtc-helper: don't disable disconnected outputs

modeset infrastructure in

    drm/i915: don't disable disconnected outputs

This was originally introduced to make encoder sharing on radone
easier for userspace, but:

- It is policy and as such belongs into userspace. E.g. personally I'm
  fairly annoyed that a flaky cable results in permanent changes of
  the desktop layout, so I'll kick out DEs which do this. Worse if the
  kernel also tries to be clever.

- It's inconsistent: We only kill disconnected outputs on setCrtc
  (which userspace might also call when just changing the
  framebuffer), but not when e.g. we receive a hpd event or in the
  output poll worker.

- It's unexpected behaviour for the userspace driver, at least in the
  intel ddx we've had tons of bugs where the driver fell over and
  killed the X session becuase pageflips/vblanks suddenly stopped
  working. We've had to fix this by wrapping every single setCrtc int
  a big "recover kms state from the kernel again" operation.

- It's suprising for the kernel, too: It took a few mails between Rob,
  Matt and me for them to notice that little dragon wreaking havoc
  with the universal plane framebuffer refcounting.

- Userspace can cope with it and e.g. Gnome already kills disconnected
  outputs and reconfigures the desktop automatically. And since there
  have been no regression reports for the i915 change from over 1 year
  ago I think all other DEs are also ready.

Note that the lines removed in this patch go back to

drm/vmwgfx: Reinstate and tighten security around legacy master model

The following restrictions affect clients connecting using legacy nodes:

*) Masters that have dropped master privilieges are not considered
   authenticated until they regain master privileges.
*) Clients whose master have dropped master privileges block interruptibly on
   ioctls  requiring authentication until their master regains master
   privileges. If their master exits, they are killed.

This is primarily designed to prevent clients authenticated with one master to
access data from clients authenticated with another master.
(Think fast user-switching or data sniffers enabled while X is vt-switched).

10 years agosupport for platform devices
Alexandre Courbot [Mon, 17 Feb 2014 06:17:26 +0000 (15:17 +0900)]
support for platform devices

Upcoming mobile Kepler GPUs (such as GK20A) use the platform bus instead
of PCI to which Nouveau is tightly dependent. This patch allows Nouveau
to handle platform devices by:

- abstracting PCI-dependent functions that were typically used for
  resource querying and page mapping,
- introducing a nv_device_is_pci() function that allows to make
  PCI-dependent code conditional,
- providing a nouveau_drm_platform_probe() function that takes a GPU
  platform device to be probed.

Core code as well as engine/subdev drivers are updated wherever possible
to make use of these functions. Some older drivers are too dependent on
PCI to be properly updated, but all newer code on which future chips may
depend should at least be runnable with platform devices.
