Replace all use of DRM_DEBUG_DRIVER in amdgpu_dm.c with drm_dbg_driver().

2025-05-12drm/msm/dp: Introduce link training per-segment for LTTPRsAleksandrs Vinarskis
DisplayPort requires per-segment link training when LTTPR are switched to non-transparent mode, starting with LTTPR closest to the source. Only when each segment is trained individually, source can link train to sink. Implement per-segment link traning when LTTPR(s) are detected, to support external docking stations. On higher level, changes are: * Pass phy being trained down to all required helpers * Run CR, EQ link training per phy * Set voltage swing, pre-emphasis levels per phy Since at least some LTTPRs (eg. Parade PS8830) do not correctly report voltage-swing, pre-emphasis level 3 support, always assume level 3 is supported. This is permitted under DP 2.1(a) section 3.6.7.2 stating that LTTPR shall set its transmitter levels as close as possible to those requested by the DPTX, if the DPTX sets the voltage swing or pre-emphasis to a level that the LTTPR does not support. It shall be noted that LTTPR’s level choosing is implementation-specific. This ensures successful link training both when connected directly to the monitor (single LTTPR onboard most X1E laptops) and via the docking station (at least two LTTPRs).

The driver handles the case where gpu fw is not in the initrd. OTOH it doesn't always handle the case where _some_ fw is in the initrd, but others are not. In particular the zap fw tends to be signed with an OEM specific key, so the paths/names differ across devices with the same SoC/GPU, so we cannot sanely list them with MODULE_FIRMWARE(). So MODULE_FIRMWARE() just ends up causing problems without actually solving anything. Remove them!

2025-05-09drm/plane: Add new plane property IN_FORMATS_ASYNCArun R Murthy
There exists a property IN_FORMATS which exposes the plane supported modifiers/formats to the user. In some platforms when asynchronous flip are used all of modifiers/formats mentioned in IN_FORMATS are not supported. This patch adds a new plane property IN_FORMATS_ASYNC to expose the async flip supported modifiers/formats so that user can use this information ahead and do flip with unsupported formats/modifiers. This will save flip failures. Add a new function pointer similar to format_mod_supported specifically for asynchronous flip. v2: Remove async variable from drm_plane (Ville) v3: Add new function pointer for async (Ville) v5: Typo corrected in commit message & some correction in the kernel documentation.

2025-05-09drm/cirrus: Use non-hybrid PCI devres APIPhilipp Stanner
cirrus enables its PCI device with pcim_enable_device(). This, implicitly, switches the function pci_request_regions() into managed mode, where it becomes a devres function. The PCI subsystem wants to remove this hybrid nature from its interfaces. To do so, users of the aforementioned combination of functions must be ported to non-hybrid functions. Replace the call to sometimes-managed pci_request_regions() with one to the always-managed pcim_request_all_regions().
