2025-01-20drm/i915: Introduce plane->can_async_flip()Ville Syrjälä
Move the "does this modifier support async flips?" check to be handled by the platform specific plane code instead of having a big mess in common code.

2025-01-20drm/i915: Allow async flips with compression on ICLVille Syrjälä
Apparently ICL can do async flips with CCS. In fact it already seems to work on GLK, but apparently can lead to underruns there so we'll only enable it for ICL.

2025-01-20drm/i915: Allow async flips with render compression on TGL+Ville Syrjälä
Looks like CCS + async flips has been a thing for a while now. Enable this for TGL+ render compression modifiers. Note that we can't update AUX_DIST during async flips we must check to make sure it remains unchanged. We also can't do clear color. Supposedly there was some attempt to make it work, but apparently the issues only got ironed out in MTL. For now we'll not worry about it and refuse async flips with clear color modifiers. Bspec claims that media compression doesn't support async flips. Based on a quick test it does seem to work to some degree, but perhaps it has issues as well. Let's trust the spec here and continue to refuse async flips + media compression.

2025-01-19drm/vc4: Remove BOs seqnosMaíra Canal
`bo->seqno`, `bo->write_seqno`, and `exec->bin_dep_seqno` are leftovers from a time when VC4 didn't support DMA Reservation Objects. Before DMA Resv was introduced, tracking the correspondence between BOs and jobs through the job's seqno made sense. However, this is no longer needed, as VC4 now supports DMA Reservation Objects and attaches the "job done" fence to the BOs. Therefore, remove the BOs seqnos in favor of using DMA Resv Objects.

2025-01-19drm/virtio: Don't return error if virtio-gpu PCI dev is not foundVivek Kasireddy
While fixing a shared VGA resource ownership issue, commit 5dd8b536bbda ("drm/virtio: Lock the VGA resources during initialization") wrongly assumed that there is always a PCI device associated with virtio-gpu and it would return error if this device is not found during init. This is incorrect, as virtio-gpu can be operated in MMIO mode (M68K) where a PCI device would probably not be created for it. Therefore, fix this issue by not erroring out if the associated PCI device is not found during initialization.

2025-01-19drm/virtio: Fix UAF in virtgpu_dma_buf_free_obj()Vivek Kasireddy
Fix the following issues identified by Smatch static checker: - The call to dma_buf_put(attach->dmabuf) after dma_buf_detach() leads to a UAF bug as dma_buf_detach() frees the attach object. Fix this by extracting the dmabuf object from attach and using that in the call to dma_buf_put(). - The resv object is extracted from attach before checking to see if attach is valid (that is !NULL) or not. Although, attach would very likely be valid, fix this by making sure that the resv object is used only after ensuring that attach is valid.

2025-01-17drm/i915/dmc_wl: Track pipe interrupt registersGustavo Sousa
Pipe interrupt registers live in their respective pipes' power wells, which are below PG0. That means that they must also be tracked as registers that are powered-off during dynamic DC states. There are probably more ranges that we need to track down and add to the powered_off_ranges. However, let's make this change only about pipe interrupt registers to fix some vblank timeouts observed due to the DMC wakelock not being taken for those registers. In the future, we might want to replace powered_off_ranges with a new table to represent registers in PG0, which should be probably easier to maintain. Any register not belonging to that table should be considered powered off during dynamic DC states and, as such, requiring the DMC wakelock for access.

2025-01-16drm/i915/cx0_phy: Update HDMI TMDS C20 algorithm valueDnyaneshwar Bhadane
In the C20 algorithm for HDMI TMDS, certain fields have been updated in the BSpec to set values for SRAM_GENERIC_<A/B>_TX_CNTX_CFG_1, such as tx_misc and dac_ctrl_range for Xe2LPD, Xe2HPD and MTL/ARL. This patch covers fields that need to be set based on the platform type. Some ARLs SoCs cannot be directly distinguished by their GMD version Id, Specifically to set value of tx_misc, so PCI Host Bridge IDs are used for differentiation. v2: - Relocate defines and Restructure the code(Jani) v3: - Replace conditions with display.platform.<platform> (jani) - Move host bridge check to new function (Jani) v4: - Identify/Replace arrowlake_u as meteorlake_u(Jani) Bspec:74165,74491 Signed-off-by: Dnyaneshwar Bhadane <dnyaneshwar.bhadane@intel.com> Reviewed-by: Suraj Kandpal <suraj.kandpal@intel.com> Signed-off-by: Matt Roper <matthew.d.roper@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20241217201301.3593054-3-dnyaneshwar.bhadane@intel.com

2025-01-16drm/xe/mmap: Add mmap support for PCI memory barrierTejas Upadhyay
In order to avoid having userspace to use MI_MEM_FENCE, we are adding a mechanism for userspace to generate a PCI memory barrier with low overhead (avoiding IOCTL call as well as writing to VRAM will adds some overhead). This is implemented by memory-mapping a page as uncached that is backed by MMIO on the dGPU and thus allowing userspace to do memory write to the page without invoking an IOCTL. We are selecting the MMIO so that it is not accessible from the PCI bus so that the MMIO writes themselves are ignored, but the PCI memory barrier will still take action as the MMIO filtering will happen after the memory barrier effect. When we detect special defined offset in mmap(), We are mapping 4K page which contains the last of page of doorbell MMIO range to userspace for same purpose. For user to query special offset we are adding special flag in mmap_offset ioctl which needs to be passed as follows, struct drm_xe_gem_mmap_offset mmo = { .handle = 0, /* this must be 0 */ .flags = DRM_XE_MMAP_OFFSET_FLAG_PCI_BARRIER, }; igt_ioctl(fd, DRM_IOCTL_XE_GEM_MMAP_OFFSET, &mmo); map = mmap(NULL, size, PROT_WRITE, MAP_SHARED, fd, mmo); IGT : https://gitlab.freedesktop.org/drm/igt-gpu-tools/-/commit/b2dbc6f22815128c0dd5c737504f42e1f1a6ad62 UMD : https://github.com/intel/compute-runtime/pull/772 V7: - Dgpu filter added V6(MAuld) - Move physical mmap to fault handler - Modify kernel-doc and attach UMD PR when ready V5(MAuld) - Return invalid early in case of non 4K PAGE_SIZE - Format kernel-doc and add note for 4K PAGE_SIZE HW limit V4(MAuld) - Add kernel-doc for uapi change - Restrict page size to 4K V3(MAuld) - Remove offset defination from UAPI to be able to change later - Edit commit message for special flag addition V2(MAuld) - Add fault handler with dummy page to handle unplug device - Add Build check for special offset to be below normal start page - Test d3hot, mapping seems to be valid in d3hot as well - Add more info to commit message Cc: Matthew Auld <matthew.auld@intel.com> Acked-by: Michal Mrozek <michal.mrozek@intel.com> Reviewed-by: Matthew Auld <matthew.auld@intel.com> Signed-off-by: Tejas Upadhyay <tejas.upadhyay@intel.com> Signed-off-by: Matthew Auld <matthew.auld@intel.com> Link: https://patchwork.freedesktop.org/patch/msgid/20250113114201.3178806-1-tejas.upadhyay@intel.com
