From 1f923a42033ad05baf755775e3339b5c319b5898 Mon Sep 17 00:00:00 2001 From: Hans Verkuil Date: Mon, 22 Sep 2014 09:27:17 -0300 Subject: [media] mem2mem_testdev: rename to vim2m This is 1) *much* easier to type, and 2) is consistent with vivid ('vi' for virtual). More of such virtual drivers are planned, so keeping the naming consistent makes sense. Note that the old module name is retained as a module alias.

Separate JPEG encoder and decoder video devices are created due to different streaming behaviour and different supported pixel formats. The hardware can not change subsampling on the fly, but encode and decode 4:2:2 subsampled JPEG images from and into this format. The CODA7541 JPEG decoder uses the bitstream buffer and thus can run without new buffers queued if there is a buffer in the bitstream. Since there is no standard way to store the colorspace used in JPEGs, and to make v4l2-compliance happy, the JPEG format always reports V4L2_COLORSPACE_JPEG.

This patch also renames struct coda_timestamp to struct coda_buffer_meta to make clear that it contains more than only the buffer timestamp.

It's possible for it to clear the hw_lock, making other instances trigger a BUG() on hw_lock checks. Since it's not fatal to clear the hw_lock to zero twice, just WARN in those cases for now. We should not explode, as firmware will return errors as needed for other instances after it's reloaded, or they will time out. A clean fix should involve killing other instances when watchdog kicks in, but requires a major redesign of locking in the driver.

Sometimes, we error out during dpb flush because of lack of src buffers. Since we have not started decoding new resolution yet, it is simpler to push zero-size buffer until we flush out all dpbs. This is already been done while handling EOS command, and this patch extends the same logic to resolution change as well.

Now that vb2-dma-sg will sync the buffers for you in the prepare/finish memops we can drop that from the drivers that use dma-sg. For the solo6x10 driver that was a bit more involved because it needs to copy JPEG or MPEG headers to the buffer before returning it to userspace, and that cannot be done in the old place since the buffer there is still setup for DMA access, not for CPU access. However, the buf_finish op is the ideal place to do this. By the time buf_finish is called the buffer is available for CPU access, so copying to the buffer is fine.
