| | | | | | | | | | | | | | | | | For MFC firmwares, improved versions with bug fixes and feature additions are released keeping the firmware version including major and minor number same.

| | | | | | | | | | | | | | | | | | | | | | fc906b6d "Remove special clock usage in driver" removed initialization of MFC special clock, arguing that there's no need to do it explicitly, since it's one of MFC gate clock's dependencies and gets enabled along with it. However, there's no promise of keeping this hierarchy across Exynos SoC releases, therefore this approach fails to provide a stable, portable solution. Out of all MFC versions, only v6 doesn't use special clock at all. For other versions log a message only in case clk_get fails, as not all the devices with the same MFC version require initializing the clock explicitly.

* [media] s5p-mfc: Don't try to resubmit VP8 bitstream buffer for decodePawel Osciak2014-05-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently, for formats that are not H264, MFC driver will check the consumed stream size returned by the firmware and, based on that, will try to decide whether the bitstream buffer contained more than one frame. If the size of the buffer is larger than the consumed stream, it assumes that there are more frames in the buffer and that the buffer should be resubmitted for decode. This rarely works though and actually introduces problems, because: - v7 firmware will always return consumed stream size equal to whatever the driver passed to it when running decode (which is the size of the whole buffer), which means we will never try to resubmit, because the firmware will always tell us that it consumed all the data we passed to it; - v6 firmware will return the number of consumed bytes, but will not include the padding ("stuffing") bytes that are allowed after the frame in VP8. Since there is no way of figuring out how many of those bytes follow the frame without getting the frame size from IVF headers (or somewhere else, but not from the stream itself), the driver tries to guess that padding size is not larger than 4 bytes, which is not always true; The only way to make it work is to queue only one frame per buffer from userspace and the check in the kernel is useless and wrong for VP8. So adding VP8 also along with H264 to disallow re-submitting of buffer back to hardware for decode.

| | | | | | | | | | | | | | | | Currently, we allocate private codec buffers on STREAMON, which may fail if we are out of memory.

* [media] s5p-mfc: Copy timestamps only when a frame is producedPawel Osciak2014-05-23
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Timestamps for destination buffers are assigned by copying them from corresponding source buffers when the decode operation results in a frame being outputted to a destination buffer. But the decision when to do this, i.e. whether the decode operation on current source buffer produced a destination frame, is wrongly based on "display status". Display status reflects the status of the destination buffer, not source. This used to work for firmwares version <= 6, because in addition to the above, we'd check the decoded frame type register, which was set to "skipped" if a destination frame was not produced, exiting early from s5p_mfc_handle_frame_new(). Firmware >=7 does not set the frame type register for frames that were not decoded anymore though, which results in us wrongly overwriting timestamps of previously decoded buffers (firmware reports the same destination buffer address as previously decoded one if a frame wasn't decoded during current operation). To do it properly, we should be basing our decision to copy the timestamp on the status of the source buffer, i.e. "decode status". The decode status register values are confusing, because in its case "display" means "a frame has been outputted to a destination buffer". We should copy if "decode and display" is returned in it. This also works on <= v6 firmware, which behaves in the same way with regards to decode status register.

* [media] vb2: stop_streaming should return voidHans Verkuil2014-04-23
| | | | | | | | | | | | | | | | | | | | | | | | The vb2 core ignores any return code from the stop_streaming op. And there really isn't anything it can do anyway in case of an error. So change the return type to void and update any drivers that implement it. The int return gave drivers the idea that this operation could actually fail, but that's really not the case. The pwc amd sdr-msi3101 drivers both had this construction: if (mutex_lock_interruptible(&s->v4l2_lock)) return -ERESTARTSYS; This has been updated to just call mutex_lock(). The stop_streaming op expects this to really stop streaming and I very much doubt this will work reliably if stop_streaming just returns without really stopping the DMA.

* [media] s5p-mfc: call wake_up_dev if in suspend modePrathyush K2013-10-28
| | | | | | | | | | | | | | | | | | | If a frame is still decoding when system enters suspend mode, we wait on the device queue for a interrupt condition. This sometimes leads to a timeout because the device queue might not be woken up everytime. Usually, the context queue gets woken up when that context's frame gets decoded. This patch adds a condition to wake up the device queue along with the context queue when the system is in suspend mode. Since the device queue is now woken up, we don't have to check the context's int_cond flag while waiting. Also, we can skip calling try_run after waking up the device queue to ensure that we don't have to wait for more than one frame to be processed.
