2025-04-22drm/amdgpu: Don't pin VRAM without DMABUF_MOVE_NOTIFYFelix Kuehling
Pinning of VRAM is for peer devices that don't support dynamic attachment and move notifiers. But it requires that all such peer devices are able to access VRAM via PCIe P2P. Any device without P2P access requires migration to GTT, which fails if the memory is already pinned for another peer device. Sharing between GPUs should not require pinning in VRAM. However, if DMABUF_MOVE_NOTIFY is disabled in the kernel build, even DMABufs shared between GPUs must be pinned, which can lead to failures and functional regressions on systems where some peer GPUs are not P2P accessible. Disable VRAM pinning if move notifiers are disabled in the kernel build to fix regressions when sharing BOs between GPUs.

2025-04-22drm/xe/guc: Cache DSS info when creating capture register listJohn Harrison
Calculating the DSS id (index of a steered register) currently requires reading state from the hwconfig table and that currently requires dynamically allocating memory. The GuC based register capture (for dev core dumps) includes this index as part of the register name in the dump. However, it was calculating said index at the time of the dump for every dump. That is wasteful. It also breaks anyone trying to do the dump at a time when memory allocations are not allowed. So rather than calculating on every print, just calculate at start of day when creating the register list in the first place.

This commit updates the dm_force_atomic_commit function to replace the usage of PTR_ERR_OR_ZERO with IS_ERR for checking error states after retrieving the Connector (drm_atomic_get_connector_state), CRTC (drm_atomic_get_crtc_state), and Plane (drm_atomic_get_plane_state) states. The function utilized PTR_ERR_OR_ZERO for error checking. However, this approach is inappropriate in this context because the respective functions do not return NULL; they return pointers that encode errors.

2025-04-22drm/amdgpu: Add queue id support to the user queue wait IOCTLArunpravin Paneer Selvam
Add queue id support to the user queue wait IOCTL drm_amdgpu_userq_wait structure. This is required to retrieve the wait user queue and maintain the fence driver references in it so that the user queue in the same context releases their reference to the fence drivers at some point before queue destruction. Otherwise, we would gather those references until we don't have any more space left and crash. v2: Modify the UAPI comment as per the mesa and libdrm UAPI comment.

2025-04-22drm/amd/display: Default IPS to RCG_IN_ACTIVE_IPS2_IN_OFFLeo Li
[Why] Recent findings show negligible power savings between IPS2 and RCG during static desktop. In fact, DCN related clocks are higher when IPS2 is enabled vs RCG. RCG_IN_ACTIVE is also the default policy for another OS supported by DC, and it has faster entry/exit. [How] Remove previous logic that checked for IPS2 support, and just default to `DMUB_IPS_RCG_IN_ACTIVE_IPS2_IN_OFF`.

2025-04-22drm/amd/display: Fix ACPI edid parsing on some Lenovo systemsMario Limonciello
[Why] The ACPI EDID in the BIOS of a Lenovo laptop includes 3 blocks, but dm_helpers_probe_acpi_edid() has a start that is 'char'. The 3rd block index starts after 255, so it can't be indexed properly. This leads to problems with the display when the EDID is parsed. [How] Change the variable type to 'short' so that larger values can be indexed.
