* drm/vmwgfx: Hook up MOBs to TTM as a separate memory typeThomas Hellstrom2014-01-17
| | | | | | | | | | To bind a buffer object as a MOB, just validate it as a MOB memory type. We are reusing the GMRID manager, although we create a new instance of it to manage MOB ids and tomake sure we don't exceed the maximum amount of MOB pages.

* drm/vmwgfx: Fix dma buffer memory size accountingThomas Hellstrom2013-12-04
| | | | | | | | | | | | | | | | | | Also request kernel ttm_buffer objects for buffer objects that obviously aren't visible to user-space, and save some device address space. The accounting was broken in a couple of ways: 1) We did not differentiate between user dma buffers and kernel dma buffers. 2) The ttm_bo_acc_size function is broken in that it a) Doesn't take into account the size of the optional dma address array, b) Doesn't take into account the fact that drivers typically embed the ttm_tt structure. This needs to be fixed in ttm, but meanwhile provide a vmwgfx-specific function to do the job.

| | | | | | | | | | | | | | | 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.

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).

This commit adds the vmwgfx driver for the VWware Virtual GPU aka SVGA. The driver is under staging the same as Nouveau and Radeon KMS. Hopefully the 2D ioctls are bug free and don't need changing, so that part of the API should be stable. But there there is a pretty big chance that the 3D API will change in the future.
