| | * | drm/exynos: add iommu support for ippEunchul Kim2012-12-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds iommu support for IPP subsystem framework. For this, it adds subdrv_probe/remove callback to enable or disable ipp iommu. We can get or put device address to a gem handle from user through exynos_drm_gem_get/put_dma_addr().

| | * | drm/exynos: add ipp subsystemEunchul Kim2012-12-14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch adds Image Post Processing(IPP) support for exynos drm driver. IPP supports image scaler/rotator and input/output DMA operations using IPP subsystem framework to control FIMC, Rotator and GSC hardware and supports some user interfaces for user side. And each IPP-based drivers support Memory to Memory operations with various converting. And in case of FIMC hardware, it also supports Writeback and Display output operations through local path. Features: - Memory to Memory operation support. - Various pixel formats support. - Image scaling support. - Color Space Conversion support. - Image crop operation support. - Rotate operation support to 90, 180 or 270 degree. - Flip operation support to vertical, horizontal or both. - Writeback operation support to display blended image of FIMD fifo on screen A summary to IPP Subsystem operations: First of all, user should get property capabilities from IPP subsystem and set these properties to hardware registers for desired operations. The properties could be pixel format, position, rotation degree and flip operation. And next, user should set source and destination buffer data using DRM_EXYNOS_IPP_QUEUE_BUF ioctl command with gem handles to source and destinition buffers. And next, user can control user-desired hardware with desired operations such as play, stop, pause and resume controls. And finally, user can aware of dma operation completion and also get destination buffer that it contains user-desried result through dequeue command. IOCTL commands: - DRM_EXYNOS_IPP_GET_PROPERTY . get ipp driver capabilitis and id. - DRM_EXYNOS_IPP_SET_PROPERTY . set format, position, rotation, flip to source and destination buffers - DRM_EXYNOS_IPP_QUEUE_BUF . enqueue/dequeue buffer and make event list. - DRM_EXYNOS_IPP_CMD_CTRL . play/stop/pause/resume control. Event: - DRM_EXYNOS_IPP_EVENT . a event to notify dma operation completion to user side. Basic control flow: Open -> Get properties -> User choose desired IPP sub driver(FIMC, Rotator or GSCALER) -> Set Property -> Create gem handle -> Enqueue to source and destination buffers -> Command control(Play) -> Event is notified to User -> User gets destinition buffer complated -> (Enqueue to source and destination buffers -> Event is notified to User) * N -> Queue/Dequeue to source and destination buffers -> Command control(Stop) -> Free gem handle -> Close Changelog v1 ~ v5: - added comments, code fixups and cleanups.

Now if we remove the current framebuffer, we cannot disable the overlay but the current framebuffer will still be freed. When fimd resumes, the dma will continue from where it left off and will throw a PAGE FAULT since the memory was freed. This patch fixes the above problem by disabling the fimd windows before disabling the fimd clocks. It also keeps track of which windows were currently active by setting the 'resume' flag. When fimd resumes, the window with a resume flag set is enabled again. Now if a current fb is removed when fimd is off, fimd_win_disable will set the 'resume' flag of that window to zero and return. So when fimd resumes, that window will not be resumed. This patch is based on the following two patches: http://git.chromium.org/gitweb/?p=chromiumos/third_party/kernel.git;a=commitdiff;h=341e973c967304976a762211b6465b0074de62ef http://git.chromium.org/gitweb/?p=chromiumos/third_party/kernel.git;a=commitdiff;h=cfa22e49b7408547c73532c4bb03de47cc034a05 These two patches are rebased onto the current kernel with additional changes like removing 'fimd_win_commit' call from the resume function since this is taken care by encoder dpms, and the modification of resume flag in win_disable.

These engines are used for ttm bo moves and VM page table updates currently. They could also be exposed via the CS ioctl for userspace use, but I haven't had a chance to add proper CS checker patches for them yet. These patches have been tested extensively internally for months, so they should be pretty solid." * 'drm-next-3.8' of git://people.freedesktop.org/~agd5f/linux: drm/radeon: use DMA engine for VM page table updates on SI drm/radeon: add dma engine support for vm pt updates on si (v2) drm/radeon: use DMA engine for VM page table updates on cayman/TN drm/radeon: add dma engine support for vm pt updates on ni (v5) drm/radeon: use async dma for ttm buffer moves on 6xx-SI drm/radeon/kms: add support for dma rings to radeon_test_moves() drm/radeon/kms: Add initial support for async DMA on SI drm/radeon/kms: Add initial support for async DMA on cayman/TN drm/radeon/kms: Add initial support for async DMA on evergreen drm/radeon/kms: Add initial support for async DMA on r6xx/r7xx
