2025-02-25drm/xe: Move survivability entirely to xe_pciLucas De Marchi
There's an odd split between xe_pci.c and xe_device.c wrt xe_survivability: it's initialized by xe_device, but then finalized by xe_pci. Move it entirely to the outer layer, xe_pci, so it controls the flow entirely. This also allows to stop ignoring some of the errors. E.g.: if there's an -ENOMEM, it shouldn't continue as if it survivability had been enabled. One change worth mentioning is that if "wait for lmem" fails, it will also check the pcode status to decide if it should enter or not in survivability mode, which it was not doing before. The bit from pcode for that decision should remain the same after lmem failed initialization, so it should be fine.

2025-02-25drm/xe: Stop setting drvdata to NULLLucas De Marchi
PCI subsystem is not supposed to call the remove() function when probe fails and doesn't need a protection for that. The only places checking for NULL drvdata, is on 2 sysfs files and they shouldn't be needed since the files are removed and reads on open fds just return an error. For this protection the core driver implementation in drivers/base/dd.c:device_unbind_cleanup() already sets it to NULL, after the release of dev resources. Remove the setting to NULL so it's possible to obtain the xe pointer from callbacks like the component unbind from device_unbind_cleanup(), i.e. after xe_pci_remove() already finished.

2025-02-25drm/msm/dpu: Fall back to a single DSC encoder (1:1:1) on small SoCsMarijn Suijten
Some SoCs such as SC7280 (used in the Fairphone 5) have only a single DSC "hard slice" encoder. The current hardcoded use of 2:2:1 topology (2 LM and 2 DSC for a single interface) make it impossible to use Display Stream Compression panels with mainline, which is exactly what's installed on the Fairphone 5. By loosening the hardcoded `num_dsc = 2` to fall back to `num_dsc = 1` when the catalog only contains one entry, we can trivially support this phone and unblock further panel enablement on mainline. A few more supporting changes in this patch ensure hardcoded constants of 2 DSC encoders are replaced to count or read back the actual number of DSC hardware blocks that are enabled for the given virtual encoder. Likewise DSC_MODE_SPLIT_PANEL can no longer be unconditionally enabled.

2025-02-25drm/msm: Use str_enable_disable-like helpersKrzysztof Kozlowski
Replace ternary (condition ? "enable" : "disable") syntax with helpers from string_choices.h because: 1. Simple function call with one argument is easier to read. Ternary operator has three arguments and with wrapping might lead to quite long code. 2. Is slightly shorter thus also easier to read. 3. It brings uniformity in the text - same string. 4. Allows deduping by the linker, which results in a smaller binary file.

[Why] DC is not using amdgpu_irq_get/put to manage the HPD interrupt refcounts. So when amdgpu_irq_gpu_reset_resume_helper() reprograms all of the IRQs, HPD gets disabled.

2025-02-25drm/amd/display: stop DML2 from removing pipes based on planesMike Katsnelson
[Why] Transitioning from low to high resolutions at high refresh rates caused grey corruption. During the transition state, there is a period where plane size is based on low resultion state and ODM slices are based on high resoultion state, causing the entire plane to be contained in one ODM slice. DML2 would turn off the pipe for the ODM slice with no plane, causing an underflow since the pixel rate for the higher resolution cannot be supported on one pipe. This change stops DML2 from turning off pipes that are mapped to an ODM slice with no plane. This is possible to do without negative consequences because pipes can now take the minimum viewport and draw with zero recout size, removing the need to have the pipe turned off. [How] In map_pipes_from_plane(), remove "check" that skips ODM slices that are not covered by the plane. This prevents the pipes for those ODM slices from being freed.

2025-02-25drm/amd/display: Increase halt timeout for DMCUB to 1sNicholas Kazlauskas
[Why] If we soft reset before halt finishes and there are outstanding memory transactions then the memory interface may produce unexpected results, such as out of order transactions when the firmware next runs. These can manifest as random or unexpected load/store violations. [How] Increase the timeout before soft reset to ensure the DMCUB has quiesced.

2025-02-25drm/amd/display: Update FIXED_VS Link Rate Toggle Workaround UsageMichael Strauss
[WHY] Previously the 128b/132b LTTPR support DPCD field was used to decide if FIXED_VS training sequence required a rate toggle before initiating LT. When running DP2.1 4.9.x.x compliance tests, emulated LTTPRs can report no-128b/132b support which is then forwarded by the FIXED_VS retimer. As a result this test exposes the rate toggle again, erroneously causing failures as certain compliance sinks don't expect this behaviour. [HOW] Add new DPCD register defines/reads to read LTTPR IEEE OUI and device ID. Decide whether to perform the rate toggle based on the LTTPR's IEEE OUI which guarantees that we only perform the toggle on affected retimers.

2025-02-25drm/amd/display: ACPI Re-timer ProgrammingRafal Ostrowski
[Why] We must implement an ACPI re-timer programming interface and notify ACPI driver whenever a PHY transition is about to take place. Because some trace lengths on certain platforms are very long, then a re-timer may need to be programmed whenever a PHY transition takes place. The implementation of this re-timer programming interface will notify ACPI driver that PHY transition is taking place and it will trigger the re-timer as needed. First we need to gather retimer information from ACPI interface. Then, in the PRE case, the re-timer interface needs to be called before we call transmitter ENABLE. In the POST case, it has to be called after we call transmitter DISABLE. [How] Implemented ACPI retimer programming interface.
