2022-05-18drm/vmwgfx: Initialize drm_mode_fb_cmd2Zack Rusin
commit 3059d9b9f6aa433a55b9d0d21b566396d5497c33 upstream. Transition to drm_mode_fb_cmd2 from drm_mode_fb_cmd left the structure unitialized. drm_mode_fb_cmd2 adds a few additional members, e.g. flags and modifiers which were never initialized. Garbage in those members can cause random failures during the bringup of the fbcon. Initializing the structure fixes random blank screens after bootup due to flags/modifiers mismatches during the fbcon bring up.

2019-03-20drm/vmwgfx: Don't double-free the mode stored in par->set_modeThomas Zimmermann
When calling vmw_fb_set_par(), the mode stored in par->set_mode gets free'd twice. The first free is in vmw_fb_kms_detach(), the second is near the end of vmw_fb_set_par() under the name of 'old_mode'. The mode-setting code only works correctly if the mode doesn't actually change.

2018-07-03drm/vmwgfx: Replace vmw_dma_buffer with vmw_buffer_objectThomas Hellstrom
Initially vmware buffer objects were only used as DMA buffers, so the name DMA buffer was a natural one. However, currently they are used also as dumb buffers and MOBs backing guest backed objects so renaming them to buffer objects is logical. Particularly since there is a dmabuf subsystem in the kernel where a dma buffer means something completely different. This also renames user-space api structures and IOCTL names correspondingly, but the old names remain defined for now and the ABI hasn't changed. There are a couple of minor style changes to make checkpatch happy.

We have had problems displaying fbdev after a resume and as a workaround we have had to call vmw_fb_refresh(). This has had a number of unwanted side-effects. The root of the problem was, however that the coalesced fbdev dirty region was not empty on the first dirty_mark() after a resume, so a flush was never scheduled.

2018-04-26drm/vmwgfx: Clean up fbdev modeset lockingThomas Hellstrom
At least since the atomic port, the vmwgfx fbdev code is taking a number of unnecessary modeset locks. In particular the kms_set_config() function will grab its own locks, leading to locking retries. So avoid drm_modeset_lock_all() and instead provide a local acquire context for kms_set_config(). Also have the vmw_kms_fbdev_init data itself grab the lock that it needs. This also fixed a long standing problem that vmw_fb_close() didn't provide an acquire context for kms_set_config(), causing potential warnings and hangs during driver unload.

I've broken this by removing the backoff handling from the set_config2atomic helper in commit 38b6441e4e75c0b319cfe4d9364c1059fc1e3c2b Author: Daniel Vetter <daniel.vetter@ffwll.ch> Date: Wed Mar 22 22:50:58 2017 +0100 drm/atomic-helper: Remove the backoff hack from set_config Fixing this properly would mean we get to wire the acquire_ctx all the way through vmwgfx fbdev code, and doing the same was tricky for the shared fbdev layer. Probably much better to look into refactoring the entire code to use the helpers, but since that's not a viable long-term solution fix the issue by open-coding a vmwgfx version of set_config, that does the legacy backoff dance internally. Note: Just compile-tested. The idea is to take drm_mode_set_config_internal(), remove the "is this a legacy driver" check, and whack the drm_atomic_legacy_backoff trickery at the end. Since drm_atomic_legacy_backoff is for atomic commits only we need to open-code it.

With this change, fbdev will be using whatever KMS backend is chosen. There are helpers available for this, so in the future we'd probably want to implement the helper callbacks instead of calling into our KMS implementation directly. v2: Make sure we take the mode_config mutex around modesetting, Also clear the initial framebuffer using vzalloc instead of vmalloc.

2015-08-05drm/vmwgfx: Add command buffer support v3Thomas Hellstrom
Add command buffer support. Currently we don't implement preemption or fancy error handling. Tested with a couple of mesa-demos, compiz/unity and viewperf maya-03. v2: - Synchronize with pending work at command buffer manager takedown. - Add an interface to flush the current command buffer for latency-critical command batches and apply it to framebuffer dirtying. v3: - Minor fixes of definitions and typos to address reviews. - Removed new or moved branch predictor hints.

2015-08-05 vmwgfx: Rework device initializationThomas Hellstrom
This commit reworks device initialization so that we always enable the FIFO at driver load, deferring SVGA enable until either first modeset or fbdev enable. This should always leave the fifo properly enabled for render- and control nodes. In addition, *) We disable the use of VRAM when SVGA is not enabled. *) We simplify PM support so that we only throw out resources on hibernate, not on suspend, since the device keeps its state on suspend.

2014-07-03drm/vmwgfx: Fix incorrect write to read-only register v2:Thomas Hellstrom
Commit "drm/vmwgfx: correct fb_fix_screeninfo.line_length", while fixing a vmwgfx fbdev bug, also writes the pitch to a supposedly read-only register: SVGA_REG_BYTES_PER_LINE, while it should be (and also in fact is) written to SVGA_REG_PITCHLOCK. This patch is Cc'd stable because of the unknown effects writing to this register might have, particularly on older device versions. v2: Updated log message.

Previously, the vmwgfx_fb driver would allow users to call FBIOSET_VINFO, but it would not adjust the FINFO properly, resulting in distorted screen rendering. The patch corrects that behaviour.

2014-03-28drm/vmwgfx: Use a per-device semaphore for reservation protectionThomas Hellstrom
Don't use a per-master semaphore (ttm lock) for reservation protection, but rather a per-device semaphore. This is needed since clients connecting using render nodes aren't master aware. The ttm lock used should probably be replaced with a reader-write semaphore once the function down_xx_interruptible() is available.

git://git.infradead.org/users/dhowells/linux-headers Pull preparatory patches for user API disintegration from David Howells: "The patches herein prepare for the extraction of the Userspace API bits from the various header files named in the Kbuild files. New subdirectories are created under either include/uapi/ or arch/x/include/uapi/ that correspond to the subdirectory containing that file under include/ or arch/x/include/. The new subdirs under the uapi/ directory are populated with Kbuild files that mostly do nothing at this time. Further patches will disintegrate the headers in each original directory and fill in the Kbuild files as they do it. These patches also: (1) fix up #inclusions of "foo.h" rather than <foo.h>. (2) Remove some redundant #includes from the DRM code. (3) Make the kernel build infrastructure handle Kbuild files both in the old places and the new UAPI place that both specify headers to be exported. (4) Fix some kernel tools that #include kernel headers during their build.

flush[_delayed]_work_sync() are now spurious. Mark them deprecated and convert all users to flush[_delayed]_work(). If you're cc'd and wondering what's going on: Now all workqueues are non-reentrant and the regular flushes guarantee that the work item is not pending or running on any CPU on return, so there's no reason to use the sync flushes at all and they're going away.
