Add debugfs support which will print source and sink status
per connector basis. Existing i915_psr_status and
i915_psr_sink_status will be used to get the source and
sink status of panel replay.
v1: Initial version. [rb-ed by Arun]
v2: Added check for DP 2.0 and connector type in connector_debugfs_add().
v3: Optimization and cosmetic changes. [Jouni]

Do not acquire a reference on the module that provides a client's
callback functions in drm_client_init(). The additional reference
prevents the user from unloading the callback functions' module and
thus creating dangling pointers.
This is only necessary if there is no direct dependency between the
caller of drm_client_init() and the provider of the callbacks in
struct drm_client_funcs. If this case ever existed, it has been
removed from the DRM code. Callers of drm_client_init() also provide
the callback implementation. The lifetime of the clients is tied to
the dependency chain's outer-most module, which is the hardware's
DRM driver. Before client helpers could be unloaded, the driver module
would have to be unloaded, which also unregisters all clients.
Driver modules that set up DRM clients can now be unloaded.

FIFO underruns are observed when FBC is enabled on plane 2 or
plane 3. Recommended WA is to update the FBC enabling sequence.
The plane binding register bits need to be updated separately
before programming the FBC enable bit.

the callers in r535_gsp_rpc_get(). Returning NULL will lead to a NULL

At least one TGL had regression when using u8 types
for entry setup frames calculation. So, let's switch
to use ints instead.
intel_psr_entry_setup_frames() function expects
to return u8 but since in case of error the error
code -ETIME is returned. This doesn't fit into u8
and hence the return value is not as expected.

DSC_Sink_BPP_Precision entry is added to i915_dsc_fec_support_show
to depict sink's precision.
Also, new debugfs entry is created to enforce fractional bpp.
If Force_DSC_Fractional_BPP_en is set then while iterating over
output bpp with fractional step size we will continue if output_bpp is
computed as integer. With this approach, we will be able to validate
DSC with fractional bpp.

DSC parameter bits_per_pixel is stored in U6.4 format.
The 4 bits represent the fractional part of the bpp.
Currently we use compressed_bpp member of dsc structure to store
only the integral part of the bits_per_pixel.
To store the full bits_per_pixel along with the fractional part,
compressed_bpp is changed to store bpp in U6.4 formats. Intergral
part is retrieved by simply right shifting the member compressed_bpp by 4.
v2:
-Use to_bpp_int, to_bpp_frac_dec, to_bpp_x16 helpers while dealing
with compressed bpp. (Suraj)
-Fix comment styling. (Suraj)
v3:
-Add separate file for 6.4 fixed point helper(Jani, Nikula)
-Add comment for magic values(Suraj)
v4:
-Fix checkpatch warnings caused by renaming(Suraj)
v5:
-Rebase.
-Use existing helpers for conversion of bpp_int to bpp_x16

Pass an instance of struct drm_format_conv_state to DRM's format
conversion helpers. Update all callers.
Most drivers can use the format-conversion state from their shadow-
plane state. The shadow plane's destroy function releases the
allocated buffer. Drivers will later be able to allocate a buffer
of appropriate size in their plane's atomic_check code.
The gud driver uses a separate thread for committing updates. For
now, the update worker contains its own format-conversion state.
Images in the format-helper tests are small. The tests preallocate
a static page for the temporary buffer. Unloading the module releases
the memory.

Currently the DRM GPUVM offers common infrastructure to track GPU VA
allocations and mappings, generically connect GPU VA mappings to their
backing buffers and perform more complex mapping operations on the GPU VA
space.
However, there are more design patterns commonly used by drivers, which
can potentially be generalized in order to make the DRM GPUVM represent
a basis for GPU-VM implementations. In this context, this patch aims
at generalizing the following elements.
1) Provide a common dma-resv for GEM objects not being used outside of
this GPU-VM.
2) Provide tracking of external GEM objects (GEM objects which are
shared with other GPU-VMs).
3) Provide functions to efficiently lock all GEM objects dma-resv the
GPU-VM contains mappings of.
4) Provide tracking of evicted GEM objects the GPU-VM contains mappings
of, such that validation of evicted GEM objects is accelerated.
5) Provide some convinience functions for common patterns.
Big thanks to Boris Brezillon for his help to figure out locking for
drivers updating the GPU VA space within the fence signalling path.

Add an abstraction layer between the drm_gpuva mappings of a particular
drm_gem_object and this GEM object itself. The abstraction represents a
combination of a drm_gem_object and drm_gpuvm. The drm_gem_object holds
a list of drm_gpuvm_bo structures (the structure representing this
abstraction), while each drm_gpuvm_bo contains list of mappings of this
GEM object.
This has multiple advantages:
1) We can use the drm_gpuvm_bo structure to attach it to various lists
of the drm_gpuvm. This is useful for tracking external and evicted
objects per VM, which is introduced in subsequent patches.
2) Finding mappings of a certain drm_gem_object mapped in a certain
drm_gpuvm becomes much cheaper.
3) Drivers can derive and extend the structure to easily represent
driver specific states of a BO for a certain GPUVM.
The idea of this abstraction was taken from amdgpu, hence the credit for
this idea goes to the developers of amdgpu.

DRM GEM objects private to a single GPUVM can use a shared dma-resv.
Make use of the shared dma-resv of GPUVM rather than a driver specific
one.
The shared dma-resv originates from a "root" GEM object serving as
container for the dma-resv to make it compatible with drm_exec.
In order to make sure the object proving the shared dma-resv can't be
freed up before the objects making use of it, let every such GEM object
take a reference on it.

The drm CI scripts for gitlab have a requirements file that makes the
github 'dependabot' worry about a few of the required tooling versions.
It wants to update the pip requirements from 23.2.1 to 23.3:
"When installing a package from a Mercurial VCS URL, e.g. pip install
hg+..., with pip prior to v23.3, the specified Mercurial revision
could be used to inject arbitrary configuration options to the hg
clone call (e.g. --config). Controlling the Mercurial configuration
can modify how and which repository is installed. This vulnerability
does not affect users who aren't installing from Mercurial"
and upgrade the urllib3 requirements from 2.0.4 to 2.0.7 due to two
issues:
"urllib3's request body not stripped after redirect from 303 status
changes request method to GET"
"`Cookie` HTTP header isn't stripped on cross-origin redirects"
The file also ends up not having a newline at the end, that my editor
ends up wanting to fix automatically.

There are two problems with the current method of determining the
virtio-gpu debug name.
1) TASK_COMM_LEN is defined to be 16 bytes only, and this is a
Linux kernel idiom (see PR_SET_NAME + PR_GET_NAME). Though,
Android/FreeBSD get around this via setprogname(..)/getprogname(..)
in libc.
On Android, names longer than 16 bytes are common. For example,
one often encounters a program like "com.android.systemui".
The virtio-gpu spec allows the debug name to be up to 64 bytes, so
ideally userspace should be able to set debug names up to 64 bytes.
2) The current implementation determines the debug name using whatever
task initiated virtgpu. This is could be a "RenderThread" of a
larger program, when we actually want to propagate the debug name
of the program.
To fix these issues, add a new CONTEXT_INIT param that allows userspace
to set the debug name when creating a context.
It takes a null-terminated C-string as the param value. The length of the
string (excluding the terminator) **should** be <= 64 bytes. Otherwise,
the debug_name will be truncated to 64 bytes.
