835a65f517 drm/nouveau: bring back blit subchannel for pre nv50 GPUs 
1ba6113a90a0 removed a lot of the kernel GPU channel, but method 0x128
was important as otherwise the GPU spams us with `CACHE_ERROR` messages.

We use the blit subchannel inside our vblank handling, so we should keep
at least this part.

v2: Only do it for NV11+ GPUs

e701156ccc drm/amd: Align SMU11 SMU_MSG_OverridePcieParameters implementation with SMU13 
SMU13 overrides dynamic PCIe lane width and dynamic speed by when on
certain hosts. commit 38e4ced804 ("drm/amd/pm: conditionally disable
pcie lane switching for some sienna_cichlid SKUs") worked around this
issue by setting up certain SKUs to set up certain limits, but the same
fundamental problem with those hosts affects all SMU11 implmentations
as well, so align the SMU11 and SMU13 driver handling.

31c7a3b378 drm/amd/pm: conditionally disable pcie lane/speed switching for SMU13 
Intel platforms such as Sapphire Rapids and Raptor Lake don't support
dynamic pcie lane or speed switching.

This limitation seems to carry over from one generation to another.
To be safer, disable dynamic pcie lane width and speed switching when
running on an Intel platform.

27655b9bb9 drm/client: Send hotplug event after registering a client 
Generate a hotplug event after registering a client to allow the
client to configure its display. Remove the hotplug calls from the
existing clients for fbdev emulation. This change fixes a concurrency
bug between registering a client and receiving events from the DRM
core. The bug is present in the fbdev emulation of all drivers.

The fbdev emulation currently generates a hotplug event before
registering the client to the device. For each new output, the DRM
core sends an additional hotplug event to each registered client.

If the DRM core detects first output between sending the artificial
hotplug and registering the device, the output's hotplug event gets
lost. If this is the first output, the fbdev console display remains
dark. This has been observed with amdgpu and fbdev-generic.

Fix this by adding hotplug generation directly to the client's
register helper drm_client_register(). Registering the client and
receiving events are serialized by struct drm_device.clientlist_mutex.
So an output is either configured by the initial hotplug event, or
the client has already been registered.

The bug was originally added in commit 6e3f17ee73 ("drm/fb-helper:
generic: Call drm_client_add() after setup is done"), in which adding
a client and receiving a hotplug event switched order. It was hidden,
as most hardware and drivers have at least on static output configured.
Other drivers didn't use the internal DRM client or still had struct
drm_mode_config_funcs.output_poll_changed set. That callback handled
hotplug events as well. After not setting the callback in amdgpu in
commit 0e3172bac3 ("drm/amdgpu: Don't set struct
drm_driver.output_poll_changed"), amdgpu did not show a framebuffer
console if output events got lost. The bug got copy-pasted from
fbdev-generic into the other fbdev emulation.

113899c266 drm/i915: Fix one wrong caching mode enum usage 
Commit a4d86249c7 ("drm/i915/gt: Provide a utility to create a scratch
buffer") mistakenly passed in uapi I915_CACHING_CACHED as argument to
i915_gem_object_set_cache_coherency(), which actually takes internal
enum i915_cache_level.

No functional issue since the value matches I915_CACHE_LLC (1 == 1), which
is the intended caching mode, but lets clean it up nevertheless.

00ae1491f9 dma-buf: fix an error pointer vs NULL bug 
Smatch detected potential error pointer dereference.

    drivers/gpu/drm/drm_syncobj.c:888 drm_syncobj_transfer_to_timeline()
    error: 'fence' dereferencing possible ERR_PTR()

The error pointer comes from dma_fence_allocate_private_stub().  One
caller expected error pointers and one expected NULL pointers.  Change
it to return NULL and update the caller which expected error pointers,
drm_syncobj_assign_null_handle(), to check for NULL instead.

f6cf3883df drm/i915: use mock device info for creating mock device 
Instead of modifying the device info on the fly, use static const mock
device info.

It's not okay to modify device info at runtime; we've added separate
runtime info for info that needs to be modified at runtime. We've added
safeguards to device info to prevent it from being modified, but commit
5e352e32ae ("drm/i915: preparation for using PAT index") just cast the
const away and modified it anyway. This prevents device info from being
moved to rodata.

Fixes: 5e352e32ae ("drm/i915: preparation for using PAT index")

27fc10d109 drm/amd/display: Fix the delta clamping for shaper LUT 
The shaper LUT requires a 10-bit value of the delta between segments. We
were using dc_fixpt_clamp_u0d10() to do that but it doesn't do what we
want it to do. It will preserve 10-bit precision after the decimal
point, but that's not quite what we want. We want 14-bit precision and
discard the 4 most-significant bytes.

To do that we'll do dc_fixpt_clamp_u0d14() & 0x3ff instead.
