| | * drm/omap: gem: Implement dma_buf importLaurent Pinchart2016-03-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | OMAP GEM objects backed by dma_buf reuse the current OMAP GEM object support as much as possible. If the imported buffer is physically contiguous its physical address will be used directly, reusing the OMAP_BO_MEM_DMA_API code paths. Otherwise it will be mapped through the TILER using a pages list created from the scatterlist instead of the shmem backing storage.

| | * drm/omap: gem: Clean up GEM objects memory flagsLaurent Pinchart2016-03-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The driver assumes that only objects backed by shmem need to be mapped through DMM. While this is true with the current code, the assumption won't hold with dma_buf import support. Condition the mapping based on whether the buffer has been allocated using the DMA mapping API instead and clean up the flags to avoid having to check both flags and GEM object filp field to decide how to process buffers. Flags are not the authoritative source of information regarding where the buffer memory comes from, and are renamed to make that clearer.

| | * drm/omap: print an error if display enable failsTomi Valkeinen2016-03-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | If the panel's enable fails, omap_encoder silently ignores the failure. omapdrm should really handle the failure, but unfortunately the whole encoder enable codepath is expected to always succeed. So for now, catch the enable failure and print an error. Signed-off-by: Tomi Valkeinen <tomi.valkeinen@ti.com> Reviewed-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com>

| | * HACK: drm/omap: always use blocking DMM fillTomi Valkeinen2016-03-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current driver uses non-blocking DMM fill when releasing memory. This gives us a small performance increase as we don't have to wait for the fill operation to finish. However, the driver does not have any error handling for non-blocking fill. In case of an error, the fill operation may silently fail, leading to leaking DMM engines, which may eventually lead to deadlock if we run out of DMM engines. This patch makes the DMM driver always use blocking fills, so that we can catch the errors. A more complex option would be to allow non-blocking fills, and implement proper error handling, but that is left for the future. This patch is a HACK, as the proper fix is to either decide to always use sync fills and remove all the async related code, or fix the async code.

| | * drm/omap: HDMI: change enable/disable to avoid sync-lostsTomi Valkeinen2016-03-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We occasionally see DISPC sync-lost errors when enabling and disabling HDMI. Sometimes we get only a few, which get handled (ignored) by the driver, but sometimes there's a flood of the errors which doesn't seem to stop. The HW team has root caused this to the order in which HDMI and DISPC are enabled/disabled. Currently we enable HDMI first, and then DISPC, and vice versa when disabling. HW team's suggestion is to do it the other way around. This patch changes the order, but this has two side effects as the pixel clock is produced by HDMI, and the clock is not running when we enable/disable DISPC: * When enabling DISPC first, we don't get vertical sync events * When disabling DISPC last, we don't get FRAMEDONE event At the moment we use both of those to verify that DISPC has been enabled/disabled properly. Thus this patch also needs to change the omapdrm and omapdss which handle the DISPC side.

| * | dma-buf: Remove range-based flushTiago Vignatti2016-02-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch removes range-based information used for optimizations in begin_cpu_access and end_cpu_access. We don't have any user nor implementation using range-based flush. It seems a consensus that if we ever want something like that again (or even more robust using 2D, 3D sub-range regions) we can use the upcoming dma-buf sync ioctl for such.

| * | drm: omapdrm: gem: Free the correct memory objectLaurent Pinchart2015-12-31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The GEM object free handler frees memory allocated by the driver using the pointer to the drm_gem_object instead of the pointer to the omap_gem_object that embeds it. This doesn't cause any issue in practice as the drm_gem_object is the first field of omap_gem_object, but would cause memory corruption if the structure layout changes. Fix it.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The plane reset handler frees the plane state and allocates a new default state, but when doing so attempt to free the plane state using the base plane state pointer instead of casting it to the driver-specific state object that has been allocated. Fix it by using the omap_plane_atomic_destroy_state() function to destroy the plane state instead of duplicating the code.
