In Xe, the perf layer allows capture of HW counter streams. These HW
counters are generally performance related but don't have to be necessarily
so. Also, the name "perf" is a carryover from i915 and is not preferred.

Here we propose the name "observation" for this common layer which allows
capture of different types of these counter streams.

If a queue is already assigned to the hardware, then a newly submitted
job can start straight away without waiting for the tick. However in
this case the devfreq infrastructure isn't notified that the GPU is
busy. By the time the tick happens the job might well have finished and
no time will be accounted for the GPU being busy.

Fix this by recording the GPU as busy directly in queue_run_job() in the
case where there is a CSG assigned and therefore we just ring the
doorbell.

point variables. The q4 notation is based on the short variant described
by

https://en.wikipedia.org/wiki/Q_(number_format)

where only the number of fraction bits in the fixed point value are
defined, while the full size is deducted from the container type, that
is the size of int for these helpers. Using the fxp_ prefix, which makes
moving these helpers outside of drm to a more generic place easier, if
they prove to be useful.

These are needed by later patches dumping the Display Stream Compression
configuration in DRM core and in the i915 driver to replace the
corresponding bpp_x16 helpers defined locally in the driver.

v2: Use the more generic/descriptive fxp_q4 prefix instead of drm_x16.

Panfrost DRM driver uses devfreq to perform DVFS, while using simple_ondemand
devfreq governor by default.  This causes driver initialization to fail on
boot when simple_ondemand governor isn't built into the kernel statically,
as a result of the missing module dependency and, consequently, the required
governor module not being included in the initial ramdisk.  Thus, let's mark
simple_ondemand governor as a softdep for Panfrost, to have its kernel module
included in the initial ramdisk.

This is a rather longstanding issue that has forced distributions to build
devfreq governors statically into their kernels, [1][2] or has forced users
to introduce some unnecessary workarounds. [3]

For future reference, not having support for the simple_ondemand governor in
the initial ramdisk produces errors in the kernel log similar to these below,
which were taken from a Pine64 RockPro64:

  panfrost ff9a0000.gpu: [drm:panfrost_devfreq_init [panfrost]] *ERROR* Couldn't initialize GPU devfreq
  panfrost ff9a0000.gpu: Fatal error during GPU init
  panfrost: probe of ff9a0000.gpu failed with error -22

Having simple_ondemand marked as a softdep for Panfrost may not resolve this
issue for all Linux distributions.  In particular, it will remain unresolved
for the distributions whose utilities for the initial ramdisk generation do
not handle the available softdep information [4] properly yet.  However, some
Linux distributions already handle softdeps properly while generating their
initial ramdisks, [5] and this is a prerequisite step in the right direction
for the distributions that don't handle them properly yet.

The SCREEN_DISABLE bit controls scanout from display memory. The bit
affects all planes, so set it only in the CRTC's atomic enable and
disable functions.

A number of bugs affect this fix. First of all, ast_set_std_regs()
tries to set VGASR1 except for the SD bit. But the read bitmask is
invert, so it preserves anything except the SD bit. Fix this by
re-inverting the read mask.

The second issue is that primary-plane and CRTC helpers modify the
SD bit. The bit controls scanout for all planes, primary and HW
cursor, so set it only in the CRTC code.

Further add a constant to represent the SD bit in VGASR1. Keep the
plane's atomic_disable around to make the DRM framework happy.

Several color registers are programmed in the DPMS code of the CRTC's
atomic_enable helper and the primary plane's atomic_update. It requires
the color format and the display mode.

Both code paths handle different cases: the DPMS's code will not be
executed if the color format changes without a full mode switch. The
plane's code only runs if the color format changes, but ignores
display-mode changes.

The color format is a property of the primary plane, so consolidate all
color-format code in the plane's atomic_update. Remove it from the DPMS
helper.

Do all mode setting in ast_crtc_helper_mode_set_nofb(), which
always runs after disabling the CRTC and before programming the
planes. Removes implicit synchronization between the CRTC's
atomic disable, enable and the vertical retrace.

Display-mode updates require HW cursors to be disabled. The HW
cursor only picks up changes at vertical retrace periods. So the
CRTC's atomic_disable helper waited for the retrace to delay any
following mode-setting operations, which then happened in
atomic_enable. See [1] for a description of the problem.

With the CRTC helper callback mode_set_nofb, we can now synchronize
and reprogram in the same place. As it always runs before the plane
update, the plane code can be reordered with the CRTC's later
atomic_enable et al.

Merge tag 'exynos-drm-fixes-for-v6.10-rc4' of git://git.kernel.org/pub/scm/linux/kernel/git/daeinki/drm-exynos into exynos-drm-next

Regression fix
- Fix an regression issue by adding 640x480 fallback mode
  for Exynos HDMI driver.

Bug fix
- Fix a memory leak by ensuring the duplicated EDID is properly freed in the get_modes function.

Code cleanup
- Remove redundant driver owner initialization since platform_driver_register() sets it automatically.

This is a variable sized array.
