be1213a341 drm/ttm: remove TTM_MEMTYPE_FLAG_FIXED v2
Instead use a boolean field in the memory manager structure.

Also invert the meaning of the field since the use of a TT
structure is the special case here.

v2: cleanup zero init.

1041dee217 drm/msm: use kthread_create_worker instead of kthread_run
Use kthread_create_worker to simplify the code and optimise
the manager struct: msm_drm_thread. With this change, we
could remove struct element (struct task_struct *thread &
struct kthread_worker worker), instead, use one point (struct
kthread_worker *worker).

7e9d4cdd65 drm/msm/dpu: move some sspp caps to dpu_caps
This isn't something that ever changes between planes, so move it to
dpu_caps struct. Making this change will allow more re-use in the
"SSPP sub blocks config" part of the catalog, in particular when adding
support for SM8150 and SM8250 which have different max_linewidth.

This also sets max_hdeci_exp/max_vdeci_exp to 0 for sc7180, as decimation
is not supported on the newest DPU versions. (note that decimation is not
implemented, so this changes nothing)

544d8b9615 drm/msm/dpu: update UBWC config for sm8150 and sm8250
Update the UBWC registers to the right values for sm8150 and sm8250.

This removes broken dpu_hw_reset_ubwc, which doesn't work because the
"force blk offset to zero to access beginning of register region" hack is
copied from downstream, where mapped region starts 0x1000 below what is
used in the upstream driver.

Also simplifies the overly complicated change that was introduced in
e4f9bbe9f8 to work around dpu_hw_reset_ubwc being broken.

32d3e0fecc drm/msm: dsi: Use OPP API to set clk/perf state
On SDM845 and SC7180 DSI needs to express a performance state
requirement on a power domain depending on the clock rates.
Use OPP table from DT to register with OPP framework and use
dev_pm_opp_set_rate() to set the clk/perf state.

dev_pm_opp_set_rate() is designed to be equivalent to clk_set_rate()
for devices without an OPP table, hence the change works fine
on devices/platforms which only need to set a clock rate.

faa0fcf943 drm/nouveau: Accept 'legacy' format modifiers
Accept the DRM_FORMAT_MOD_NVIDIA_16BX2_BLOCK()
family of modifiers to handle broken userspace
Xorg modesetting and Mesa drivers. Existing Mesa
drivers are still aware of only these older
format modifiers which do not differentiate
between different variations of the block linear
layout. When the format modifier support flag was
flipped in the nouveau kernel driver, the X.org
modesetting driver began attempting to use its
format modifier-enabled framebuffer path. Because
the set of format modifiers advertised by the
kernel prior to this change do not intersect with
the set of format modifiers advertised by Mesa,
allocating GBM buffers using format modifiers
fails and the modesetting driver falls back to
non-modifier allocation. However, it still later
queries the modifier of the GBM buffer when
creating its DRM-KMS framebuffer object, receives
the old-format modifier from Mesa, and attempts
to create a framebuffer with it. Since the kernel
is still not aware of these formats, this fails.

Userspace should not be attempting to query format
modifiers of GBM buffers allocated with a non-
format-modifier-aware allocation path, but to
avoid breaking existing userspace behavior, this
change accepts the old-style format modifiers when
creating framebuffers and applying them to planes
by translating them to the equivalent new-style
modifier. To accomplish this, some layout
parameters must be assumed to match properties of
the device targeted by the relevant ioctls. To
avoid perpetuating misuse of the old-style
modifiers, this change does not advertise support
for them. Doing so would imply compatibility
between devices with incompatible memory layouts.

Tested with Xorg 1.20 modesetting driver,
weston@c46c70dac84a4b3030cd05b380f9f410536690fc,
gnome & KDE wayland desktops from Ubuntu 18.04,
and sway 1.5

ca8199f134 drm/msm/dpu: ensure device suspend happens during PM sleep
"The PM core always increments the runtime usage counter
before calling the ->suspend() callback and decrements it
after calling the ->resume() callback"

DPU and DSI are managed as runtime devices. When
suspend is triggered, PM core adds a refcount on all the
devices and calls device suspend, since usage count is
already incremented, runtime suspend was not getting called
and it kept the clocks on which resulted in target not
entering into XO shutdown.

Add changes to force suspend on runtime devices during pm sleep.

Changes in v1:
 - Remove unnecessary checks in the function
    _dpu_kms_disable_dpu (Rob Clark).

Changes in v2:
 - Avoid using suspend_late to reset the usagecount
   as suspend_late might not be called during suspend
   call failures (Doug).

Changes in v3:
 - Use force suspend instead of managing device usage_count
   via runtime put and get API's to trigger callbacks (Doug).

Changes in v4:
 - Check the return values of pm_runtime_force_suspend and
   pm_runtime_force_resume API's and pass appropriately (Doug).

Changes in v5:
 - With v4 patch, test cycle has uncovered issues in device resume.

   On bubs: cmd tx failures were seen as SW is sending panel off
   commands when the dsi resources are turned off.

   Upon suspend, DRM driver will issue a NULL composition to the
   dpu, followed by turning off all the HW blocks.

   v5 changes will serialize the NULL commit and resource unwinding
   by handling them under PM prepare and PM complete phases there by
   ensuring that clks are on when panel off commands are being
   processed.

Changes in v6:
- Use drm_mode_config_helper_suspend/resume() instead of legacy API
  drm_atomic_helper_suspend/resume() (Doug).

  Trigger runtime callbacks from the suspend/resume call to turn
  off the resources.

Changes in v7:
- Add "__maybe_unused" to the functions to avoid compilation
  failures. Cleanup unnecessary configs (Doug).

08af4769c7 drm/msm: handle for EPROBE_DEFER for of_icc_get
Check for errors instead of silently not using icc if the msm driver
probes before the interconnect driver.

Allow ENODATA for ocmem path, as it is optional and this error
is returned when "gfx-mem" path is provided but not "ocmem".

Because msm_gpu_cleanup assumes msm_gpu_init has been called, the icc path
init needs to be after msm_gpu_init for the error path to work.

These never get set back to 0 when probing fails, so an attempt to probe
again results in broken behavior. Fix the problem by setting thse to zero

178b0013f0 drm/amdgpu/dc: Stop dma_resv_lock inversion in commit_tail
Trying to grab dma_resv_lock while in commit_tail before we've done
all the code that leads to the eventual signalling of the vblank event
(which can be a dma_fence) is deadlock-y. Don't do that.

Here the solution is easy because just grabbing locks to read
something races anyway. We don't need to bother, READ_ONCE is
equivalent. And avoids the locking issue.

v2: Also take into account tmz_surface boolean, plus just delete the
old code.
