We might to use that function separately from intel_dp_dsc_compute_config
for DP DSC over MST case, because allocating bandwidth in that
case can be a bit more tricky. So in order to avoid code copy-pasta
lets extract this to separate function and reuse it for both SST
and MST cases.
v2: Removed m
Fix intel_dp_dsc_compute_config, previously timeslots parameter
was used in fact not as a timeslots, but more like a ratio
timeslots/64, which of course didn't have any effect for SST DSC,
but causes now issues for MST DSC.
Secondly we need to calculate pipe_bpp using intel_dp_dsc_compute_bpp

Initialize the generic fbdev emulation even if it has been disabled
on the kernel command line. The hotplug and mode initialization will
fail accordingly.
The kernel parameter can still be changed at runtime and the emulation
will initialize after hotplugging the connector.

Rename drm_fb_helper_alloc_fbi() to drm_fb_helper_alloc_info() as

Don't set struct drm_driver.output_poll_changed. It's used to restore
the fbdev console. But as amdgpu uses generic fbdev emulation, the
console is being restored by the DRM client helpers already. See the
functions drm_kms_helper_hotplug_event() and
drm_kms_helper_connector_hotplug_event() in drm_
Rename struct drm_fb_helper.fbdev to info. The current name is
misleading as it overlaps with generic fbdev naming conventions.
Adapt to the usual naming in fbdev drivers by calling the field
'info'. No functional changes.

Uncouple the parameter drm_leak_fbdev_smem from the implementation by
setting a flag in struct drm_fb_helper. This will help to move the
generic fbdev emulation into its own source file, while keeping the
parameter in drm_fb_helper.c. No functional changes.

Implement the fbdev's read/write helpers with the same functions. Use
the generic fbdev's code as template. Convert all drivers.
DRM's fb helpers must implement regular I/O functionality in struct
fb_ops and possibly perform a damage update. Handle all this in the
same functions and convert driver

The fbdev helpers implement a damage worker that forwards fbdev
updates to the DRM driver. The worker's update logic depends on
the generic fbdev emulation. Separate the two via function pointer.
The generic fbdev emulation sets struct drm_fb_helper_funcs.fb_dirty,

Hi,
I'm facing a couple of issues when testing KUnit with the i915 driver.
The DRM subsystem and the i915 driver has, for a long time, his own
way to do unit tests, which seems to be added before KUnit.
I'm now checking if it is worth start using KUnit at i915. So, I wrote

Don't populate the read-only array en_di on the stack but instead
make it static. Also makes the object code a little smaller.

This series adds a new function component_match_add_of to simplify the
common case of calling component_match_add_release with
component_release_of and component_compare_of. There is already
drm_of_component_match_add, which allows for a custom compare function.
However, all existing users just use
Every user of this function either uses component_compare_of or
something equivalent. Most of them immediately put the device node as
well. Convert these users to component_match_add_of and remove
drm_of_component_match_add.
