in case of using two drivers such as fimd and hdmi controller that they have their own hardware interrupt, drm framework doesn't provide pipe number corresponding to it. so the pipe should be set to event's from specific crtc. Signed-off-by:

this patch adds the following comments and code clean. - add comment of exynos_drm_crtc_apply() call at page flip time. - add comment that when exynos_drm_fbdev_reinit() is called, why num_connector is 0 and also the framebuffers should be destroyed. - remove buf_off member from struct exynos_drm_overlay because this member isn't used anymore.

This shrinks the sizes of a lot of functions in the radeon driver dramatically. With a non force inline + -Os kernel this is default anyways. Cc: David Airlie <airlied@linux.ie> Signed-off-by:

This fixes kernel panics when running the vbltest from the drm repo. We can't just skip initializing the vblank system since it sets up certain state for us, see: "vmwgfx: Enable use of the vblank system." Signed-off-by:

Looks like the same pcie gen2 speed initialization for Evergreen also works on Cayman and seems to come up fine, so enable it if the module parameter says so Signed-off-by:

Enabling pcie gen2 speed was skipped for Northern Islands AISCs, although it looks like it works just fine with the same initialization sequence used for evergreen. According to Alex D. gen2 init was skipped to prevent a crash that has been caused by some other bug that has been fixed in the meantime; so now it should be safe to enable it. Signed-off-by:

Add a way to send DRM events down the gpu fifo by attaching them to fence objects. This may be useful for Xserver swapbuffer throttling and page-flip done notifications. Bump version to 2.2 to signal the availability of the FENCE_EVENT ioctl. Signed-off-by:

If a card wasn't PCIE, we always set the DMA mask to 32 bits. This is only applies to the old rage128/r1xx gart block on early radeon asics (~r1xx-r4xx). Newer PCI and IGP cards can handle 40 bits just fine. Signed-off-by:

The value of RADEON_DEBUGFS_MAX_NUM_FILES has been used to specify the size of an array, each element of which looks like this: struct radeon_debugfs { struct drm_info_list *files; unsigned num_files; }; Consequently, the number of debugfs files may be much greater than RADEON_DEBUGFS_MAX_NUM_FILES, something that the current code ignores: if ((_radeon_debugfs_count + nfiles) > RADEON_DEBUGFS_MAX_NUM_FILES) { DRM_ERROR("Reached maximum number of debugfs files.\n"); DRM_ERROR("Report so we increase RADEON_DEBUGFS_MAX_NUM_FILES.\n"); return -EINVAL; } This commit fixes this make, and accordingly renames: RADEON_DEBUGFS_MAX_NUM_FILES to: RADEON_DEBUGFS_MAX_COMPONENTS Signed-off-by:Michael Witten <mfwitten@gmail.com> Signed-off-by:

When force == false, we don't do load detection in the connector detect functions. Unforunately, we also return the previous connector state so we never get disconnect events for DVI-I, DVI-A, or VGA. Save whether we detected the monitor via load detection previously and use that to determine whether we return the previous state or not.

DVI-D and HDMI-A are digital only, so there's no need to attempt analog load detect. Also, skip bail before the !force check, or we fail to get a disconnect events. The next patches in the series attempt to fix disconnect events for connectors with analog support (DVI-I, HDMI-B, DVI-A). Fixes: https://bugs.freedesktop.org/show_bug.cgi?id=41561Signed-off-by:

Commit 9b9fe724 accidentally used RADEON_GPIO_EN_* where RADEON_GPIO_MASK_* was intended. This caused improper initialization of I2C buses, mostly visible when setting i2c_algo_bit.bit_test=1. Using the right constants fixes the problem. Signed-off-by:

Contexts, surfaces and streams allocate persistent kernel memory as the direct result of user-space requests. Make sure this memory is accounted as graphics memory, to avoid DOS vulnerabilities. Also take the TTM read lock around resource creation to block switched-out dri clients from allocating resources. Signed-off-by:

This patch is a DRM Driver for Samsung SoC Exynos4210 and now enables only FIMD yet but we will add HDMI support also in the future. this patch is based on git repository below: git://people.freedesktop.org/~airlied/linux.git branch name: drm-next commit-id: 88ef4e3f you can refer to our working repository below: http://git.infradead.org/users/kmpark/linux-2.6-samsung branch name: samsung-drm We tried to re-use lowlevel codes of the FIMD driver(s3c-fb.c based on Linux framebuffer) but couldn't so because lowlevel codes of s3c-fb.c are included internally and so FIMD module of this driver has its own lowlevel codes. We used GEM framework for buffer management and DMA APIs(dma_alloc_*) for buffer allocation so we can allocate physically continuous memory for DMA through it and also we could use CMA later if CMA is applied to mainline. Refer to this link for CMA(Continuous Memory Allocator): http://lkml.org/lkml/2011/7/20/45 this driver supports only physically continuous memory(non-iommu). Links to previous versions of the patchset: v1: < https://lwn.net/Articles/454380/ > v2: < http://www.spinics.net/lists/kernel/msg1224275.html > v3: < http://www.spinics.net/lists/dri-devel/msg13755.html > v4: < http://permalink.gmane.org/gmane.comp.video.dri.devel/60439 > v5: < http://comments.gmane.org/gmane.comp.video.dri.devel/60802 > Changelog v2: DRM: add DRM_IOCTL_SAMSUNG_GEM_MMAP ioctl command. this feature maps user address space to physical memory region once user application requests DRM_IOCTL_SAMSUNG_GEM_MMAP ioctl. DRM: code clean and add exception codes. Changelog v3: DRM: Support multiple irq. FIMD and HDMI have their own irq handler but DRM Framework can regiter only one irq handler this patch supports mutiple irq for Samsung SoC. DRM: Consider modularization. each DRM, FIMD could be built as a module. DRM: Have indenpendent crtc object. crtc isn't specific to SoC Platform so this patch gets a crtc to be used as common object. created crtc could be attached to any encoder object. DRM: code clean and add exception codes. Changelog v4: DRM: remove is_defult from samsung_fb. is_default isn't used for default framebuffer. DRM: code refactoring to fimd module. this patch is be considered with multiple display objects and would use its own request_irq() to register a irq handler instead of drm framework's one. DRM: remove find_samsung_drm_gem_object() DRM: move kernel private data structures and definitions to driver folder. samsung_drm.h would contain only public information for userspace ioctl interface. DRM: code refactoring to gem modules. buffer module isn't dependent of gem module anymore. DRM: fixed security issue. DRM: remove encoder porinter from specific connector. samsung connector doesn't need to have generic encoder. DRM: code clean and add exception codes. Changelog v5: DRM: updated fimd(display controller) driver. added various pixel formats, color key and pixel blending features. DRM: removed end_buf_off from samsung_drm_overlay structure. this variable isn't used and end buffer address would be calculated by each sub driver. DRM: use generic function for mmap_offset. replaced samsung_drm_gem_create_mmap_offset() and samsung_drm_free_mmap_offset() with generic ones applied to mainline recentrly. DRM: removed unnecessary codes and added exception codes. DRM: added comments and code clean. Changelog v6: DRM: added default config options. DRM: added padding for 64-bit align. DRM: changed prefix 'samsung' to 'exynos' Signed-off-by:

Previously, query results could be placed in any buffer object, but since we didn't allow pinned buffer objects, query results could be written when that buffer was evicted, corrupting data in other buffers. Now, require that buffers holding query results are no more than two pages large, and allow one single pinned such buffer. When the command submission code encounters query result structures in other buffers, the queries in the pinned buffer will be finished using a query barrier for the last hardware context using the buffer. Also if the command submission code detects that a new hardware context is used for queries, all queries of the previous hardware context is also flushed. Currently we use waiting for a no-op occlusion query as a query barrier for a specific context. The query buffer is also flushed and unpinned on context destructions, master drops and before scanout bo placement. Signed-off-by:
