2024-07-26drm/xe/rtp: Fix off-by-one when processing rulesLucas De Marchi
Gustavo noticed an odd "+ 2" in rtp_mark_active() while processing rtp rules and pointed that it should be "+ 1". In fact, while processing entries without actions (OOB workarounds), if the WA is activated and has OR rules, it will also inadvertently activate the very next workaround. Test in a LNL B0 platform by moving 18024947630 on top of 16020292621, makes the latter become active: $ cat /sys/kernel/debug/dri/0/gt0/workarounds ...

2024-07-25drm/ci: update link to Gitlab serverDeborah Brouwer
Before building an image, the build script looks to see if there are fixes to apply from an upstream repository. The link for the upstream repository git://anongit.freedesktop.org/drm/drm became obsolete with the move to Gitlab server in March 2024. Until recently, this obsolete link was harmless because anongit would at least respond that there were no such fixes available. In the last few days anongit has stopped responding to requests causing the build script to hang indefinitely. Update the link from anongit to the Gitlab server to prevent the build script from hanging indefinitely.

git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core Pull driver core updates from Greg KH: "Here is the big set of driver core changes for 6.11-rc1. Lots of stuff in here, with not a huge diffstat, but apis are evolving which required lots of files to be touched. Highlights of the changes in here are: - platform remove callback api final fixups (Uwe took many releases to get here, finally!) - Rust bindings for basic firmware apis and initial driver-core interactions. It's not all that useful for a "write a whole driver in rust" type of thing, but the firmware bindings do help out the phy rust drivers, and the driver core bindings give a solid base on which others can start their work. There is still a long way to go here before we have a multitude of rust drivers being added, but it's a great first step. - driver core const api changes. This reached across all bus types, and there are some fix-ups for some not-common bus types that linux-next and 0-day testing shook out. This work is being done to help make the rust bindings more safe, as well as the C code, moving toward the end-goal of allowing us to put driver structures into read-only memory.

Make vmwgfx go through the dma-buf interface to map/unmap imported buffers. The driver used to try to directly manipulate external buffers, assuming that everything that was coming to it had to live in cpu accessible memory. While technically true because what's in the vms is controlled by us, it's semantically completely broken. Fix importing of external buffers by forwarding all memory access requests to the importer. Tested by the vmw_prime basic_vgem test.

2024-07-24drm/vmwgfx: Fix handling of dumb buffersZack Rusin
Dumb buffers can be used in kms but also through prime with gallium's resource_from_handle. In the second case the dumb buffers can be rendered by the GPU where with the regular DRM kms interfaces they are mapped and written to by the CPU. Because the same buffer can be written to by the GPU and CPU vmwgfx needs to use vmw_surface (object which properly tracks dirty state of the guest and gpu memory) instead of vmw_bo (which is just guest side memory). Furthermore the dumb buffer handles are expected to be gem objects by a lot of userspace. Make vmwgfx accept gem handles in prime and kms but internally switch to vmw_surface's to properly track the dirty state of the objects between the GPU and CPU. Fixes new kwin and kde on wayland.

2024-07-24drm/vmwgfx: Make sure the screen surface is ref countedZack Rusin
Fix races issues in virtual crc generation by making sure the surface the code uses for crc computation is properly ref counted. Crc generation was trying to be too clever by allowing the surfaces to go in and out of scope, with the hope of always having some kind of screen present. That's not always the code, in particular during atomic disable, so to make sure the surface, when present, is not being actively destroyed at the same time, hold a reference to it.

2024-07-24drm/vmwgfx: Fix a deadlock in dma buf fence pollingZack Rusin
Introduce a version of the fence ops that on release doesn't remove the fence from the pending list, and thus doesn't require a lock to fix poll->fence wait->fence unref deadlocks. vmwgfx overwrites the wait callback to iterate over the list of all fences and update their status, to do that it holds a lock to prevent the list modifcations from other threads. The fence destroy callback both deletes the fence and removes it from the list of pending fences, for which it holds a lock. dma buf polling cb unrefs a fence after it's been signaled: so the poll calls the wait, which signals the fences, which are being destroyed. The destruction tries to acquire the lock on the pending fences list which it can never get because it's held by the wait from which it was called. Old bug, but not a lot of userspace apps were using dma-buf polling interfaces. Fix those, in particular this fixes KDE stalls/deadlock.
