Changelog v3: make exynos_drm_display_power function use exynos_drm_best_encoder function instead of connector->encoder to get a valid encoder. connector->encoder could be NULL because with DRM_IOCTL_MODE_RMFB request, connector->encoder is NULL so fix this issue. Changelog v2: remove static prefix so that exynos_drm_best_encoder function could be called by other modules. Changelog v1: this patch fixes the issue that display power callback isn't called. with DRM_IOCTL_MODE_RMFB request, encoder->connector becomes NULL so display_ops->power_on() wouldn't be called so this patch makes exynos_drm_best_encoder function to be used to get a valid encoder of each connector.

this patch ensures that each plane connected to encoder is disabled when released, by adding disable callback function of encoder helper we had faced with one issue that invalid memory is accessed by dma once drm is released and then the dma is turned on again. actually, in our case, page fault was incurred with iommu. the reason is that a gem buffer accessed by the dma is also released once drm is released. so this patch would fix this issue ensuring the dma is disabled when released.

if old_crtc isn't same as encoder->crtc then it means that user changed crtc id to another one so a plane to old_crtc should be disabled so that current plane can be updated safely and plane->crtc should be set to new crtc(encoder->crtc) Signed-off-by: NInki Dae <inki.dae@samsung.com> Signed-off-by: NKyungmin Park <kyungmin.park@samsung.com>

this patch fixes that when drm_crtc_helper_set_mode() is called, mode data for hardware overlay and conntroller are updated two times. for example, in case that drm_crtc_helper_set_mode() is called, overlay_ops->commit() and manager_ops->commit() callbacks can be called two times, first at drm_crtc_helper_set_mode() and second at drm_helper_connector_dpms().

The encoder get_crtc operation is called to retrieve a pointer to the CRTC the encoder is currenctly connected to, right after setting the encoder::crtc field to the new CRTC. The implementation of this operation returns the pointer to the new CRTC, which is then pointlessly compared to itself. As the operation is not mandatory, don't implement it.

The exynos drm driver has several subdrv. They each can be module but it causes unfixed probe order of exynodr drm driver and each subdrv. It also needs some weird codes such as exynos_drm_fbdev_reinit and exynos_drm_mode_group_reinit. This patch can remove weird codes and clear codes through we doesn't modularity each subdrv. Also this removes unnecessary codes related module.

The exynos fimd supports 5 window overlays. Only one window overlay of fimd is used by the crtc, so we need plane feature to use the rest window overlays.

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.
