2016-09-19gpu: ipu-v3: Add queued image conversion supportSteve Longerbeam5-1/+1932
This patch implements image conversion support using the IC tasks, with tiling to support scaling to and from images up to 4096x4096. Image rotation is also supported. Image conversion requests are added to a run queue under the IC tasks. The internal API is subsystem agnostic (no V4L2 dependency except for the use of V4L2 fourcc pixel formats). Callers prepare for image conversion by calling ipu_image_convert_prepare(), which initializes the parameters of the conversion. The caller passes in the ipu and IC task to use for the conversion, the input and output image formats, a rotation mode, and a completion callback and completion context pointer: struct ipu_image_converter_ctx * ipu_image_convert_prepare(struct ipu_soc *ipu, enum ipu_ic_task ic_task, struct ipu_image *in, struct ipu_image *out, enum ipu_rotate_mode rot_mode, ipu_image_converter_cb_t complete, void *complete_context); A new conversion context is created that is added to an IC task context queue. The caller is given the new conversion context, which can then be passed to the further APIs: int ipu_image_convert_queue(struct ipu_image_converter_run *run); This queues the given image conversion request run to a run queue, and starts the conversion immediately if the run queue is empty. Only the physaddr's of the input and output image buffers are needed, since the conversion context was created previously with ipu_image_convert_prepare(). When the conversion completes, the run pointer is returned to the completion callback. void ipu_image_convert_abort(struct ipu_image_converter_ctx *ctx); This will abort any active or pending conversions for this context. Any currently active or pending runs belonging to this context are returned via the completion callback with an error status. void ipu_image_convert_unprepare(struct ipu_image_converter_ctx *ctx); Unprepares the conversion context. Any active or pending runs will be aborted by calling ipu_image_convert_abort(). Signed-off-by: Steve Longerbeam <[email protected]> Signed-off-by: Philipp Zabel <[email protected]>

2016-09-19gpu: ipu-v3: fix a possible NULL dereferenceLABBE Corentin1-3/+3
of_match_device could return NULL, and so cause a NULL pointer dereference later. For fixing this problem, we use of_device_get_match_data(), this will simplify the code a little by using a standard function for getting the match data. Testing the return value of of_device_get_match_data is also necessary for avoiding a second NULL deref later on devtype.

Similar to struct drm_update_draw, struct drm_mode_fb_cmd2 has an unaligned 64 bit field (modifier). This get packed differently between 32 bit and 64 bit modes on architectures that can handle unaligned 64 bit access (X86 and IA64).
