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.

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.

2011-10-05vmwgfx: Fix up query processingThomas Hellstrom
Previously, query results could be placed in any buffer object, but since we didn't allow pinned buffer objects, query results could be written when that buffer was evicted, corrupting data in other buffers. Now, require that buffers holding query results are no more than two pages large, and allow one single pinned such buffer. When the command submission code encounters query result structures in other buffers, the queries in the pinned buffer will be finished using a query barrier for the last hardware context using the buffer. Also if the command submission code detects that a new hardware context is used for queries, all queries of the previous hardware context is also flushed. Currently we use waiting for a no-op occlusion query as a query barrier for a specific context. The query buffer is also flushed and unpinned on context destructions, master drops and before scanout bo placement.

2011-09-06vmwgfx: Fix confusion caused by using "fence" in various placesThomas Hellstrom
This is needed before we introduce the fence objects. Otherwise this will be even more confusing. The plan is to use the following: seqno: A 32-bit sequence number that may be passed in the fifo. marker: Objects, carrying a seqno, that track fifo submission time. They are used for fifo lag based throttling. fence objects: Kernel space objects, possibly accessible from user-space and carrying a 32-bit seqno together with signaled status.

2010-10-01vmwgfx: vt-switch (master drop) fixesThomas Hellstrom
We add an option not to enable fbdev, this option is off (0) by default. Not enabling fbdev at load time makes it possible to co-operate with vga16fb and vga text mode when VT switching. However, if 3D resources are active when VT switching, we're currently not able to switch over to vga, due to device limitations. This fixes a bug where we previously lost 3D state during VT switch.
