2019-04-08drm/vmwgfx: Use preprocessor macro for FIFO allocationDeepak Rawat1-5/+4
Whenever FIFO allocation fails an error message is printed to dmesg. Since this is common operation a lot of similar messages are scattered everywhere. Use preprocessor macro to remove this cluttering. Signed-off-by: Deepak Rawat <drawat@vmware.com> Reviewed-by: Thomas Hellstrom <thellstrom@vmware.com>

2014-01-17drm/vmwgfx: Fix the driver for large dma addressesThomas Hellstrom1-157/+3
With dma compliance / IOMMU support added to the driver in kernel 3.13, the dma addresses can exceed 44 bits, which is what we support in 32-bit mode and with GMR1. So in 32-bit mode and optionally in 64-bit mode, restrict the dma addresses to 44 bits, and strip the old GMR1 code.

2013-11-12drm/vmwgfx: Fix a couple of compile / sparse warnings and errorsThomas Hellstrom1-2/+5
Fixes *) an implicit function declaration on mips, *) a defined but not used label on !CONFIG_INTEL_IOMMU *) Hopefully a couple of sparse warnings where we implicitly typecast integer to __le32 and vice versa.

2013-11-06drm/vmwgfx: Use the linux DMA api to get valid device addresses of pagesThomas Hellstrom1-74/+76
The code handles three different cases: 1) physical page addresses. The ttm page array is used. 2) DMA subsystem addresses. A scatter-gather list is used. 3) Coherent pages. The ttm dma pool is used, together with the dma_ttm array os dma_addr_t Signed-off-by: Thomas Hellstrom <thellstrom@vmware.com> Reviewed-by: Jakob Bornecrantz <jakob@vmware.com>

Use Ben's new range manager hooks to implement a manager for GMRs that manages ids rather than ranges. This means we can use the standard TTM code for binding, unbinding and eviction. Signed-off-by: Thomas Hellstrom <thellstrom@vmware.com> Signed-off-by: Dave Airlie <airlied@redhat.com>
2009-12-15drm/vmwgfx: Add DRM driver for VMware Virtual GPUJakob Bornecrantz1-0/+213
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.
