[Why & How]
On Framework laptops with DDR5 modules, underflow can be observed.
It's unclear why it only occurs on specific desktop contents. However,
increasing enter/exit latencies by 3us seems to resolve it.

The commit 6a23e7b433 ("drm/amd: Clean up kfd node on surprise
disconnect") introduced early KFD cleanup when drm_dev_is_unplugged()
returns true. However, this causes hangs during normal module unload
(rmmod amdgpu).
The issue occurs because drm_dev_unplug() is called in amdgpu_pci_remove()
for all removal scenarios, not just surprise disconnects. This was done
intentionally in commit 39934d3ed5 ("Revert "drm/amdgpu: TA unload
messages are not actually sent to psp when amdgpu is uninstalled"") to
fix IGT PCI software unplug test failures. As a result,
drm_dev_is_unplugged() returns true even during normal module unload,
triggering the early KFD cleanup inappropriately.
The correct check should distinguish between:
- Actual surprise disconnect (eGPU unplugged): pci_dev_is_disconnected()
returns true
- Normal module unload (rmmod): pci_dev_is_disconnected() returns false
Replace drm_dev_is_unplugged() with pci_dev_is_disconnected() to ensure
the early cleanup only happens during true hardware disconnect events.

Some shimmer/colorful points appears when using the steamOS color
pipeline for HDR on gaming with DCN32. These points look like black
values being wrongly mapped to red/blue/green values. It was caused
because the number of hw points in regular LUTs and in a shaper LUT was
treated as the same.
DCN3+ regular LUTs have 257 bases and implicit deltas (i.e. HW
calculates them), but shaper LUT is a special case: it has 256 bases and
256 deltas, as in DCN1-2 regular LUTs, and outputs 14-bit values.
Fix that by setting by decreasing in 1 the number of HW points computed
in the LUT segmentation so that shaper LUT (i.e. fixpoint == true) keeps
the same DCN10 CM logic and regular LUTs go with `hw_points + 1`.

[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.
