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:

Make surfaces swappable. Make sure we honor the maximum amount of surface memory the device accepts. This is done by potentially reading back surface contents not used by the current command submission and storing it locally in buffer objects. Signed-off-by:

Use a list for resources referenced during command submission, instead of an array. As long as we don't implement parallell command submission this works fine and simplifies things a bit. 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:

Add / fix some function comments. Don't move out an fbdev framebuffer when unused. Just unpin. Only have a single function that computes a SVGAGuestPtr from the buffer's current placement, and make it more versatile by accepting a struct ttm_buffer_object Signed-off-by:

Since some somewhat questionable changes a while back, TTM provides a completely empty array of struct dma_address that stays around for the entire lifetime of the TTM object. Lets use this array, *always*, rather than wasting yet more memory on another array who's purpose is identical, as well as yet another bool array of the same size saying *which* of the previous two arrays to use... This change will also solve the high order allocation failures seen by some people while using nouveau. Signed-off-by:Ben Skeggs <bskeggs@redhat.com>
