DRM: add DRM Driver for Samsung SoC EXYNOS4210. 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: 88ef4e3f4f616462b78a7838eb3ffc3818d30f67 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).

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: 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.

DRM: add DRM Driver for Samsung SoC EXYNOS4210. 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: 88ef4e3f4f616462b78a7838eb3ffc3818d30f67 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).

DRM: add DRM Driver for Samsung SoC EXYNOS4210. 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: 88ef4e3f4f616462b78a7838eb3ffc3818d30f67 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).

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.

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: 88ef4e3f4f616462b78a7838eb3ffc3818d30f67 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: Don't force all planes to be added to the state due to zpos We don't want all planes to be added to the state whenever a plane with fixed zpos gets enabled/disabled. This is true especially for eg. cursor planes on i915, as we want cursor updates to go through w/o throttling. Same holds for drivers that don't support zpos at all (i915 actually falls into this category right now since we've not yet added zpos support). Allow drivers more freedom by letting them deal with zpos themselves instead of doing it in drm_atomic_helper_check_planes() unconditionally. Let's just inline the required calls into all the driver that currently depend on this. v2: Inline the stuff into the drivers instead of adding another helper, document things better (Daniel) Cc: Daniel Vetter <daniel@ffwll.ch> Cc: Marek Szyprowski <m.szyprowski@samsung.com> Cc: Benjamin Gaignard <benjamin.gaignard@linaro.org> Cc: Vincent Abriou <vincent.abriou@st.com> Cc: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Cc: Inki Dae <inki.dae@samsung.com> Cc: Joonyoung Shim <jy0922.shim@samsung.com> Cc: Seung-Woo Kim <sw0312.kim@samsung.com> Cc: Kyungmin Park <kyungmin.park@samsung.com> Cc: Lyude <cpaul@redhat.com> Cc: Maarten Lankhorst <maarten.lankhorst@linux.intel.com> Cc: stable@vger.kernel.org Fixes: 44d1240d006c ("drm: add generic zpos property") Signed-off-by: Ville Syrjälä <ville.syrjala@linux.intel.com> Reviewed-by: Sean Paul <seanpaul@chromium.org> Acked-by: Benjamin Gaignard <benjamin.gaignard@linaro.org> Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch> Link: http://patchwork.freedesktop.org/patch/msgid/1476111056-12734-1-git-send-email-ville.syrjala@linux.intel.com
