2014-07-22[media] coda: add workqueue to serialize hardware commandsPhilipp Zabel1-88/+74
Using the coda_mutex lock to serialize hardware access would cause "INFO: possible circular locking dependency detected" lockdep warnings. Since the possible locking paths are hard to follow, serialize hardware access with a single workqueue thread. Ultimately the workqueue could be converted to only do register setup and readout for per-command work items. Using the initialized context property, SEQ_END is only queued in coda_release when needed.

2014-07-22[media] coda: add selection API support for h.264 decoderPhilipp Zabel1-0/+94
The h.264 decoder produces capture frames that are a multiple of the macroblock size (16 pixels). To inform userspace about invalid pixel data at the edges, use the active and padded composing rectangles on the capture queue. The cropping information is obtained from the h.264 sequence parameter set.

2014-07-22[media] coda: Add encoder/decoder support for CODA960Philipp Zabel2-47/+466
This patch adds support for the CODA960 VPU in Freescale i.MX6 SoCs. It enables h.264 and MPEG4 encoding and decoding support. Besides the usual register shifting, the CODA960 gains frame memory control and GDI registers that are set up for linear mapping right now, needs ENC_PIC_SRC_INDEX to be set beyond the number of internal buffers for some reason, and has subsampling buffers that need to be set up. Also, the work buffer size is increased to 80 KiB. The CODA960 firmware spins if there is not enough input data in the bitstream buffer. To make it continue, buffers need to be copied into the bitstream as soon as they are queued. As the bitstream fifo is written into from two places, it must be protected with a mutex. For that, using a threaded interrupt handler is necessary.

For MFC firmwares, improved versions with bug fixes and feature additions are released keeping the firmware version including major and minor number same. The issue came with the release of a new MFCv6 firmware with an interface change. This patch adds the support of accepting multiple firmware binaries for every version with the driver trying to load firmwares starting from latest.

X-Patchwork-Delegate: mchehab@redhat.com Remove the CONFIG_ prefix from two Kconfig symbols in a dependency for SMS_SIANO_DEBUGFS. This prefix is invalid inside Kconfig files. Note that the current (common sense) dependency on SMS_USB_DRV and SMS_SDIO_DRV being equal ensures that SMS_SIANO_DEBUGFS will not violate its constraints. These constraint are that: - it should only be built if SMS_USB_DRV is set; - it can't be builtin if USB support is modular. So drop the dependency on SMS_USB_DRV, as it is unneeded.

2014-07-22[media] v4l2-ioctl: don't set PRIV_MAGIC unconditionally in g_fmt()Hans Verkuil1-6/+22
Regression fix: V4L2_PIX_FMT_PRIV_MAGIC should only be set for the VIDEO_CAPTURE and VIDEO_OUTPUT buffer types, and not for any others. In the case of the win format this overwrote a pointer value that is passed in from userspace. Just set it for V4L2_BUF_TYPE_VIDEO_CAPTURE and OUTPUT only. Set it before the callback is called, just as is done for try/s_fmt, and again afterwards in case the driver zeroed it. The latter was missing in try/s_fmt, so add it there as well. Currently it is quite likely that drivers clear priv (that was needed for a long time), so it makes sense to set it twice.

2014-07-22[media] v4l2-ioctl: set V4L2_CAP_EXT_PIX_FORMAT for device_capsHans Verkuil1-0/+1
V4L2_CAP_EXT_PIX_FORMAT is set for capabilities, but it needs to be set for device_caps as well: device_caps should report all caps relevant to the device node, and this is one of them.

2014-07-22[media] v4l2-ctrls: fix corner case in round-to-range codeHans Verkuil1-3/+14
If you have a maximum that is at the limit of what the type supports, and the step is > 1, then you can get wrap-around errors since the code assumes that the maximum that the type supports is ctrl->maximum + ctrl->step / 2. In practice this is always fine, but in artificially crafted ranges you will hit this bug. Since this is core code it should just work. This bug has always been there but since it doesn't cause problems in practice it was never noticed.

2014-07-22[media] vb2: fix bytesused == 0 handlingHans Verkuil1-40/+38
The original report from Nikhil was that if data_offset > 0 and bytesused == 0, then the check in __verify_length() would fail, even though the spec says that if bytes_used == 0, then it will be replaced by the actual length of the buffer. After digging into it a bit more I realized that there were several other things wrong: - in __verify_length() it would use the application-provided length value for USERPTR and the vb2 core length for other memory models, but it should have used the application-provided length as well for DMABUF. - in __fill_vb2_buffer() on the other hand it would replace bytesused == 0 by the application-provided length, even for MMAP buffers where the length is determined by the vb2 core. - in __fill_vb2_buffer() it tries to figure out if all the planes have bytesused == 0 before it will decide to replace bytesused by length. However, the spec makes no such provision, and it makes for convoluted code. So just replace any bytesused == 0 by the proper length. The idea behind this was that you could use bytesused to signal empty planes, something that is currently not supported. But that is better done in the future by using one of the reserved fields in strucy v4l2_plane. This patch fixes all these issues.
