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.

2015-01-19drm/vmwgfx: Replace the hw mutex with a hw spinlockThomas Hellstrom
Fixes a case where we call vmw_fifo_idle() from within a wait function with task state !TASK_RUNNING, which is illegal. In addition, make the locking fine-grained, so that it is performed once for every read- and write operation. This is of course more costly, but we don't perform much register access in the timing critical paths anyway. Instead we have the extra benefit of being sure that we don't forget the hw lock around register accesses. I think currently the kms code was quite buggy w r t this.

2013-01-20drm/vmwgfx: add proper framebuffer refcountingDaniel Vetter
Afact vmwgfx already has all the right refcounting implemented on the backing storage, and we only need to ensure that the drm fb doesn't disappear untimely. So holding onto the fb reference from _lookup until vmw_kms_present has completed should be enough. Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>
2013-01-20drm: create drm_framebuffer_lookupDaniel Vetter
And replace all fb lookups with it. Also add a WARN to drm_mode_object_find since that is now no longer the blessed interface to look up an fb. And add kerneldoc to both functions. This only updates all callsites, but immediately drops the acquired refence again. Hence all callers still rely on the fact that a mode fb can't disappear while they're holding the struct mutex. Subsequent patches will instate proper use of refcounts, and then rework the rmfb and unref code to no longer serialize fb destruction with the mode_config lock. We don't want that since otherwise a compositor might end up stalling for a few frames in rmfb. v2: Don't use kref_get_unless_zero - Greg KH doesn't like that kind of interface.

2013-01-20drm: revamp locking around fb creation/destructionDaniel Vetter
Well, at least step 1. The goal here is that framebuffer objects can survive outside of the mode_config lock, with just a reference held as protection. The first step to get there is to introduce a special fb_lock which protects fb lookup, creation and destruction, to make them appear atomic. This new fb_lock can nest within the mode_config lock. But the idea is (once the reference counting part is completed) that we only quickly take that fb_lock to lookup a framebuffer and grab a reference, without any other locks involved. vmwgfx is the only driver which does framebuffer lookups itself, also wrap those calls to drm_mode_object_find with the new lock. Also protect the fb_list walking in i915 and omapdrm with the new lock. As a slight complication there's also the list of user-created fbs attached to the file private. The problem now is that at fclose() time we need to walk that list, eventually do a modeset call to remove the fb from active usage (and are required to be able to take the mode_config lock), but in the end we need to grab the new fb_lock to remove the fb from the list. The easiest solution is to add another mutex to protect this per-file list. Currently that new fbs_lock nests within the modeset locks and so appears redudant. But later patches will switch around this sequence so that taking the modeset locks in the fb destruction path is optional in the fastpath. Ultimately the goal is that addfb and rmfb do not require the mode_config lock, since otherwise they have the potential to introduce stalls in the pageflip sequence of a compositor (if the compositor e.g. switches to a fullscreen client or if it enables a plane). But that requires a few more steps and hoops to jump through. Note that framebuffer creation/destruction is now double-protected - once by the fb_lock and in parts by the idr_lock. The later would be unnecessariy if framebuffers would have their own idr allocator. But that's material for another patch (series). v2: Properly initialize the fb->filp_head list in _init, otherwise the newly added WARN to check whether the fb isn't on a fpriv list any more will fail for driver-private objects. v3: Fixup two error-case unlock bugs spotted by Richard Wilbur.

2013-01-20drm/vmwgfx: use drm_modeset_lock_allDaniel Vetter
Ok, this one here is a bit more complicated, and I can't really claim to fully understand the locking and lifetime rules of the vmwgfx driver. So just convert ever mutex_lock call, including the interruptible one. Since other places (e.g. in the execbuf ioctl) take the mode_config.mutex without bothering with interruptible handling, I've figured I should be able to get away with this in a few more places ...
