[PATCH] radeon: fix r600/agp when vram is after AGP (v2)
by Dave Airlie 17 Apr '12

17 Apr '12

From: Dave Airlie <airlied(a)redhat.com> If AGP is placed in the middle, the size_af is off-by-one, it results in VRAM being placed at 0x7fffffff instead of 0x8000000. v2: fix the vram_start setup.

[PATCH 00/11] Integration of videobuf2 with dmabuf
by Tomasz Stanislawski 17 Apr '12

17 Apr '12

Hello everyone, This patchset adds support for DMABUF [2] importing to V4L2 stack. It was updated after Laurent Pinchart's review. The support for DMABUF exporting was moved to separate patchset due to dependency on patches for DMA mapping redesign by Marek Szyprowski [4]. v3: - rebased on mainline 3.4-rc1 - split 'code refactor' patch to multiple smaller patches - squashed fixes to Sumit's patches - patchset is no longer dependant on 'DMA mapping redesign' - separated path for handling IO … [View More]and non-IO mappings - add documentation for DMABUF importing to V4L - removed all DMABUF exporter related code - removed usage of dma_get_pages extension v2: - extended VIDIOC_EXPBUF argument from integer memoffset to struct v4l2_exportbuffer - added patch that breaks DMABUF spec on (un)map_atachment callcacks but allows to work with existing implementation of DMABUF prime in DRM - all dma-contig code refactoring patches were squashed - bugfixes v1: List of changes since [1]. - support for DMA api extension dma_get_pages, the function is used to retrieve pages used to create DMA mapping. - small fixes/code cleanup to videobuf2 - added prepare and finish callbacks to vb2 allocators, it is used keep consistency between dma-cpu acess to the memory (by Marek Szyprowski) - support for exporting of DMABUF buffer in V4L2 and Videobuf2, originated from [3]. - support for dma-buf exporting in vb2-dma-contig allocator - support for DMABUF for s5p-tv and s5p-fimc (capture interface) drivers, originated from [3] - changed handling for userptr buffers (by Marek Szyprowski, Andrzej Pietrasiewicz) - let mmap method to use dma_mmap_writecombine call (by Marek Szyprowski) [1] http://thread.gmane.org/gmane.linux.drivers.video-input-infrastructure/4296… [2] https://lkml.org/lkml/2011/12/26/29 [3] http://thread.gmane.org/gmane.linux.drivers.video-input-infrastructure/3635… [4] http://thread.gmane.org/gmane.linux.kernel.cross-arch/12819 Andrzej Pietrasiewicz (1): v4l: vb2-dma-contig: add support for scatterlist in userptr mode Laurent Pinchart (2): v4l: vb2-dma-contig: Shorten vb2_dma_contig prefix to vb2_dc v4l: vb2-dma-contig: Reorder functions Marek Szyprowski (2): v4l: vb2: add prepare/finish callbacks to allocators v4l: vb2-dma-contig: add prepare/finish to dma-contig allocator Sumit Semwal (4): v4l: Add DMABUF as a memory type v4l: vb2: add support for shared buffer (dma_buf) v4l: vb: remove warnings about MEMORY_DMABUF v4l: vb2: Add dma-contig allocator as dma_buf user Tomasz Stanislawski (2): Documentation: media: description of DMABUF importing in V4L2 v4l: vb2-dma-contig: Remove unneeded allocation context structure Documentation/DocBook/media/v4l/compat.xml | 4 + Documentation/DocBook/media/v4l/io.xml | 177 +++++++ .../DocBook/media/v4l/vidioc-create-bufs.xml | 1 + Documentation/DocBook/media/v4l/vidioc-qbuf.xml | 15 + Documentation/DocBook/media/v4l/vidioc-reqbufs.xml | 8 +- drivers/media/video/videobuf-core.c | 4 + drivers/media/video/videobuf2-core.c | 195 +++++++- drivers/media/video/videobuf2-dma-contig.c | 536 +++++++++++++++++--- include/linux/videodev2.h | 8 + include/media/videobuf2-core.h | 38 ++ 10 files changed, 910 insertions(+), 76 deletions(-) -- 1.7.5.4 [View Less]

[PATCH] xf86drm.c: add counter for ioctl restarting
by Anton V. Boyarshinov 16 Apr '12

16 Apr '12

In some cases ioclt->alarm->ioctl loop can be infinite: ioctl(7, 0x40086482, 0xbfb62738) = ? ERESTARTSYS (To be restarted) --- SIGALRM (Alarm clock) @ 0 (0) --- sigreturn() = ? (mask now []) ioctl(7, 0x40086482, 0xbfb62738) = ? ERESTARTSYS (To be restarted) and forever. It seems, that limiting ioctl restarting by some resonable number of trys is a dirty but working way to prevent Xorg lockups. Signed-off-by: Anton V. Boyarshinov <boyarsh(a)… [View More]

[PATCH resend 1/2] drm: Fix EDID color format parsing
by Lars-Peter Clausen 16 Apr '12

16 Apr '12

The code should obviously check the EDID feature field for EDID feature flags and not the color_formats field of the drm_display_info struct. Also update the color_formats field with new modes instead of overwriting the current mode.
