drm/amd/display: Add CRC 32-bit mode support for DCN3.6+
[Why]
DCN 3.6+ hardware supports CRC-32 polynomial in addition to the
legacy CRC-16. Enable 32-bit CRC values per color component for
improvement of precision in display validation.
[How]
When userspace sets crc_poly_mode (0=CRC-16, 1=CRC-32) via the debugfs
interface, the value is stored in dm_irq_params.crc_poly_mode. When CRC
source configuration triggers amdgpu_dm_crtc_configure_crc_source(),
crc_poly_mode is retrieved from dm_irq_params and passed to
dc_stream_configure_crc().
In the DC layer, dc_stream_configure_crc() sets crc_poly_mode into the
crc_params structure and passes it to optc35_configure_crc(). If the
hardware supports the OTG_CRC_POLY_SEL register, the register is
programmed to select CRC-16 or CRC-32 polynomial.
When reading CRC values, optc35_get_crc() checks whether CRC32 register
masks are available. If present, it reads 32-bit CRC values from
OTG_CRC0/1_DATA_R32/G32/B32 registers; otherwise, it falls back
to reading 16-bit CRC values from legacy OTG_CRC0/1_DATA_RG/B
registers.

drm/exynos: vidi: use priv->vidi_dev for ctx lookup in vidi_connection_ioctl()
vidi_connection_ioctl() retrieves the driver_data from drm_dev->dev to
obtain a struct vidi_context pointer. However, drm_dev->dev is the
exynos-drm master device, and the driver_data contained therein is not
the vidi component device, but a completely different device.
This can lead to various bugs, ranging from null pointer dereferences and
garbage value accesses to, in unlucky cases, out-of-bounds errors,
use-after-free errors, and more.
To resolve this issue, we need to store/delete the vidi device pointer in
exynos_drm_private->vidi_dev during bind/unbind, and then read this

[Why]
When usb4 link training fails, the dpia sym clock will be disabled and SYMCLK

assumed that link training succeeded and will switch from refclk to
phy clock. But phy clk here might not be on. Dig reg access timeout

When enable_stream is hit, check if link training failed for usb4.

drm/amdgpu: fix NULL pointer dereference in amdgpu_gmc_filter_faults_remove
On APUs such as Raven and Renoir (GC 9.1.0, 9.2.2, 9.3.0), the ih1 and
ih2 interrupt ring buffers are not initialized. This is by design, as
these secondary IH rings are only available on discrete GPUs. See
vega10_ih_sw_init() which explicitly skips ih1/ih2 initialization when
AMD_IS_APU is set.
However, amdgpu_gmc_filter_faults_remove() unconditionally uses ih1 to
get the timestamp of the last interrupt entry. When retry faults are
enabled on APUs (noretry=0), this function is called from the SVM page
fault recovery path, resulting in a NULL pointer dereference when
amdgpu_ih_decode_iv_ts_helper() attempts to access ih->ring[].
This issue was exposed by commit 1446226d32a4 ("drm/amdgpu: Remove GC HW
IP 9.3.0 from noretry=1") which changed the default for Renoir APU from
noretry=1 to noretry=0, enabling retry fault handling and thus
exercising the buggy code path.
Fix this by adding a check for ih1.ring_size before attempting to use
it. Also restore the soft_ih support from commit dd299441654f ("drm/amdgpu:
Rework retry fault removal"). This is needed if the hardware doesn't
support secondary HW IH rings.

drm/i915/display: Prevent u64 underflow in intel_fbc_stolen_end
Static analysis reveals a potential integer underflow in
intel_fbc_stolen_end. This can apparently occur if
intel_parent_stolen_area_size returns zero (or, theoretically, any value
less than 2^23), as 2^23 is subtracted from the return value and stored
in a u64. While this doesn't appear to cause any issues due to the use
of the min() function to clamp the return values from the
intel_fbc_stolen_end function, it would be best practice to avoid
undeflowing values like this on principle. So, rework the function to
prevent the underflow from occurring. Note that the underflow at
present would result in the value of intel_fbc_cfb_base_max being
returned at the end of intel_fbc_stolen_end, so just return that if the
value of intel_parent_stolen_area_size is too small.

path for readability.
