Thanks to Ville for suggesting this as a potential solution to pipe
underruns on Skylake.
On Skylake all of the registers for configuring planes, including the
registers for configuring their watermarks, are double buffered. New
values written to them won't take effect until said registers are

Use instead __copy_from_user_inatomic() and fallback to slow-path where
we drop and re-aquire the lock in case of fault.

An evil userspace could try to cause deadlock by passing an unfaulted-in
GEM bo as submit->bos (or submit->cmds) table. Which will trigger
msm_gem_fault() while we already hold struct_mutex. See:

This patchset adds the simpledrm driver by David Herrmann based on a
patchset[1] from 2014. That patchset also included patches for kicking
out simpledrm by real drivers. I have stayed away from that since it
involves another subsystem and I would probably be unable to answer any
questions about th
Export of_chosen so drivers built as modules can get access to it.
The simpledrm driver will use this and is compatible with
simple-framebuffer which is a subnode of /chosen.

This adds a function that also takes the console lock before calling
fb_set_suspend() in contrast to drm_fb_helper_set_suspend() which is
a plain wrapper around fb_set_suspend().
Resume is run asynchronously using a worker if the console lock is
already taken. This is modelled after the i915 driver

Changes from version 3:
- Remove #ifdef CONFIG_DRM_FBDEV_EMULATION
- Use drm_fb_helper_set_suspend_lock
There is currently no non-fbdev mechanism in place to kick out
simpledrm when the real hw-driver is probed. As a stop gap until
that is in place, honour remove_conflicting_framebuffers() and
delete the simple-framebuffer platform device when it's called.

The SimpleDRM driver binds to simple-framebuffer devices and provides a
DRM/KMS API. It provides only a single CRTC+encoder+connector combination
plus one initial mode.
Userspace can create dumb-buffers which can be blit into the real
framebuffer similar to UDL. No access to the real framebuffer i

Thanks, but what are t
We always need to remove conflicting framebuffers if any other fb driver
is enabled, and not just if we are setting up an fbdev ourselves.
Unfortunately remove_conflicting_framebuffers() was incorrectly stubbed
out if !fbdev rather than !fb leading to major memory corruption (and
corrupt filesyste

This is an initial swing at getting the adv7511 hdmi bridge
audio support reviewed.
I've taken the core audio work done by Lars-Peter Clausen, and
adapted by Srinivas Kandagatla and Archit Taneja, and tried to
rework it to use the hdmi-codec sound driver.

This patch moves the adv7511 data structure to header file so that the

This patch adds support to Audio for both adv7511 and adv7533
bridge chips.
This patch was originally from [1] by Lars-Peter Clausen
and was adapted by Archit Taneja and
Srinivas Kandagatla .
Then I heavily reworked it to use the hdmi-codec driver. So credit
to them, but blame to me.
