media: videodev2.h: RGB BT2020 and HSV are always full range

2020-11-05T10:51:18Z

[ Upstream commit b305dfe2e93434b12d438434461b709641f62af4 ] The default RGB quantization range for BT.2020 is full range (just as for all the other RGB pixel encodings), not limited range. Update the V4L2_MAP_QUANTIZATION_DEFAULT macro and documentation accordingly. Also mention that HSV is always full range and cannot be limited range. When RGB BT2020 was introduced in V4L2 it was not clear whether it should be limited or full range, but full range is the right (and consistent) choice.

media: media/v4l2: remove V4L2_FLAG_MEMORY_NON_CONSISTENT flag

2020-09-14T13:28:06Z

The patch partially reverts some of the UAPI bits of the buffer cache management hints. Namely, the queue consistency (memory coherency) user-space hint because, as it turned out, the kernel implementation of this feature was misusing DMA_ATTR_NON_CONSISTENT. The patch reverts both kernel and user space parts: removes the DMA consistency attr functions, rolls back changes to v4l2_requestbuffers, v4l2_create_buffers structures and corresponding UAPI functions (plus compat32 layer) and cleans up the documentation.

Pull remoteproc updates from Bjorn Andersson: "This introduces a new "detached" state for remote processors that are deemed to be running at the time Linux boots and the infrastructure for "attaching" to these. It then introduces the support for performing this operation for the STM32 platform. The coredump functionality is moved out from the core file and gains support for an optional mode where the recovery phase awaits the notification from devcoredump that the dump should be released. This allows userspace to grab the coredump in scenarios where vmalloc space is too low for creating a complete copy of the coredump before handing this to devcoredump. A new character device based interface is introduced to allow tying the stoppage of a remote processor to the termination of a user space process. This is useful in situations when such process provides crucial resources/operations for the firmware running on the remote processor. The Texas Instrument K3 driver gains support for the C66x and C71x DSPs. Qualcomm remoteprocs gains support for stashing relocation information in IMEM, to aid post mortem debugging and the crash notification mechanism is generalized to be reusable in cases where loosely coupled drivers needs to know about the status of a remote processor. One such example is the IPA hardware block, which is jointly owned with the modem and migrated to this improved interface. It also introduces a number of bug fixes and debug improvements for the Qualcomm modem remoteproc driver. And it cleans up the inconsistent interface for remoteproc drivers to implement power management" * tag 'rproc-v5.9' of git://git.kernel.org/pub/scm/linux/kernel/git/andersson/remoteproc: (56 commits) remoteproc: core: Register the character device interface remoteproc: Add remoteproc character device interface remoteproc: kill IPA notify code net: ipa: new notification infrastructure remoteproc: k3-dsp: Add support for C71x DSPs dt-bindings: remoteproc: k3-dsp: Update bindings for C71x DSPs remoteproc: k3-dsp: Add support for L2RAM loading on C66x DSPs remoteproc: k3-dsp: Add a remoteproc driver of K3 C66x DSPs dt-bindings: remoteproc: Add bindings for C66x DSPs on TI K3 SoCs remoteproc: k3: Add TI-SCI processor control helper functions remoteproc: Introduce rproc_of_parse_firmware() helper dt-bindings: arm: keystone: Add common TI SCI bindings remoteproc: qcom_q6v5_mss: Remove redundant running state remoteproc: qcom: q6v5: Update running state before requesting stop remoteproc: qcom_q6v5_mss: Add modem debug policy support remoteproc: qcom_q6v5_mss: Validate modem blob firmware size before load remoteproc: qcom_q6v5_mss: Validate MBA firmware size before load rpmsg: update documentation remoteproc: qcom_q6v5_mss: Add MBA log extraction support remoteproc: Add coredump debugfs entry ...

remoteproc: Add remoteproc character device interface

2020-08-05T03:16:37Z

Add the character device interface into remoteproc framework. This interface can be used in order to boot/shutdown remote subsystems and provides a basic ioctl based interface to implement supplementary functionality. An ioctl call is implemented to enable the shutdown on release feature which will allow remote processors to be shutdown when the controlling userspace application crashes or hangs.

media: docs: dev-decoder: Add one more reason for dynamic change

2020-07-04T10:42:39Z

Add bit-depth change as one more reason which could change in the middle of the stream. For the worst case the stream is 8bit at the beginning but later in the bit-stream it changes to 10bit. That change should be propagated to the client so that it can take the appropriate action. In that case it has to stop the streaming on the capture queue, re-negotiate the pixel format, allocate new buffers and start the streaming again.
