Add a short delay before clamping to idle frequency on active->idle
transition. It takes ~0.5ms to increase the freq again on the next
idle->active transition, so this helps avoid extra freq transitions
on workloads that bounce between CPU and GPU.

Hooray! We've managed to hit enough bugs upstream that I've been able to
come up with a pretty solid explanation for how backlight controls are
actually supposed to be detected and used these days. As well, having the
rest of the PWM bits in VESA's backlight interface implemented seems to
have
Now that we've added support to i915 for controlling panel backlights that
need PWM to be enabled/disabled, let's finalize this and add support for
controlling brightness levels via PWM as well. This should hopefully put us
towards the path of supporting _ALL_ backlights via VESA's DPCD interface
This simply adds proper support for panel backlights that can be controlled
via VESA's backlight control protocol, but which also require that we
enable and disable the backlight via PWM instead of via the DPCD interface.
We also enable this by default, in order to fix some people's backlights
When I originally moved all of the VESA backlight code in i915 into DRM
helpers, one of the things I didn't have the hardware or time for
testing was machines that used a combination of PWM and DPCD in order to
control their backlights. This has since then caused some breakages and
resulted in us

Due to a simple typo (apparently I can't count. It goes 0, 1, 2 and
not 0, 2, 3) we were getting a kernel doc warning that looked like
this:

In general that change looks good. But what configuration is that?
Background is that it doesn't make much sense to compile the amdgpu
driver on systems where resource_size_t is only 32bit.

It will never be consumed unless someone writes a board file - the
runtime
Any objections that I just push patches 1-7 to drm-misc-next?

We currently just evict lmem objects to system memory when under memory
pressure, and in the next patch we want to use the shmem backend even
for this case. For this case we lack the usual object mm.pages, which
effectively hides the pages from the i915-gem shrinker, until we
actually "attach" the
Drop the atomic shrink_pin stuff, and just have make_{un}shrinkable
update the shrinker visible lists immediately. This at least simplifies
the next patch, and does make the behaviour more obvious. The potential
downside is that make_unshrinkable now grabs a global lock even when the

This should let us do an accelerated copy directly to the shmem pages
when temporarily moving lmem-only objects, where the i915-gem shrinker
can later kick in to swap out the pages, if needed.
