If I apply it, I think the comments should also be changed to "Supported Link Speed" instead of "Current." The only in-tree user of these symbols is drm_pcie_get_speed_cap_mask(). Dave, can you ack/nack this? I don't want to apply this if it's going to break something there. Bjorn

[PATCH] drm/exynos: Add exynos drm specific fb_mmap function
by Rahul Sharma 09 Nov '12

09 Nov '12

From: Prathyush K <prathyush.k(a)samsung.com> This patch adds a exynos drm specific implementation of fb_mmap which supports mapping a non-contiguous buffer to user space. This new function does not assume that the frame buffer is contiguous and calls dma_mmap_writecombine for mapping the buffer to user space. dma_mmap_writecombine will be able to map a contiguous buffer as well as non-contig buffer depending on whether an IOMMU mapping is created for drm or not.

[PATCH 0/8] vmwgfx stuff for -next
by Thomas Hellstrom 09 Nov '12

09 Nov '12

This patch series should be applied after the drm/ttm: Get rid of a number of atomic read-modify-write ops vX patch series. It contains various improvements. Patch 7 is a rewrite of the resource management and is intended to pave the way for an upcoming hardware version change, and to ease implementation of multi-thread command submission. Patch 8 adds a previously vmware-internal header so that we make sure we compute the surface memory requirement the same way as the virtual device does. The same file is intended to be used by mesa. Thanks, Thomas

Hi Linus, dropped the ball on a vmware patch, so two more fixes for vmwgfx are here, one for hibernate issue, one for a BUG trigger. Dave.
