2011-09-06vmwgfx: Fix confusion caused by using "fence" in various placesThomas Hellstrom8-109/+107
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.

2011-09-01vmwgfx: Restrict number of GMR pages to device limitThomas Hellstrom3-11/+49
When GMR2 is available, make sure we restrict the number of used GMR pages to the limit indicated by the device. This is done by failing a GMRID allocation if the total number of GMR pages exceeds the limit. As a result TTM will then start evicting buffers in GMR memory on a LRU basis until the allocation succeeds.

2011-09-01vmwgfx: Fix potential execbuf deadlocksThomas Hellstrom4-48/+139
Perform all command stream validation in a bounce buffer separate from the fifo. This makes the fifo available to all validation-generated commands, which would otherwise attempt to grab the fifo recursively, causing a deadlock. This is in preparation for GMR2 and swappable surfaces. Also maintain references to all surfaces in the command stream until the command stream has been fired in order to avoid racing with surface destruction taking place after validation but before submission.

2011-08-31drm/ttm: add a way to bo_wait for either the last read or last writeMarek Olšák1-0/+1
Sometimes we want to know whether a buffer is busy and wait for it (bo_wait). However, sometimes it would be more useful to be able to query whether a buffer is busy and being either read or written, and wait until it's stopped being either read or written. The point of this is to be able to avoid unnecessary waiting, e.g. if a GPU has written something to a buffer and is now reading that buffer, and a CPU wants to map that buffer for read, it needs to only wait for the last write. If there were no write, there wouldn't be any waiting needed. This, or course, requires user space drivers to send read/write flags with each relocation (like we have read/write domains in radeon, so we can actually use those for something useful now). Now how this patch works: The read/write flags should passed to ttm_validate_buffer. TTM maintains separate sync objects of the last read and write for each buffer, in addition to the sync object of the last use of a buffer. ttm_bo_wait then operates with one the sync objects.

2011-01-27ttm: Expand (*populate) to support an array of DMA addresses.Konrad Rzeszutek Wilk1-1/+2
We pass in the array of ttm pages to be populated in the GART/MM of the card (or AGP). Patch titled: "ttm: Utilize the DMA API for pages that have TTM_PAGE_FLAG_DMA32 set." uses the DMA API to make those pages have a proper DMA addresses (in the situation where page_to_phys or virt_to_phys do not give use the DMA (bus) address). Since we are using the DMA API on those pages, we should pass in the DMA address to this function so it can save it in its proper fields (later patches use it).
