UVC defines a method of handling asynchronous controls, which sends a USB packet over the interrupt pipe. This patch implements support for such packets by sending a control event to the user. Since this can involve USB traffic and, therefore, scheduling, this has to be done in a work queue. Signed-off-by:

When a command ends up in a STALL on the control pipe, use the Request Error Code control to provide a more precise error information to the user. For example, if a camera is still busy processing a control, when the same or an interrelated control set request arrives, the camera can react with a STALL and then return the "Not ready" status in response to a UVC_VC_REQUEST_ERROR_CODE_CONTROL command. With this patch the user would then get an EBUSY error code instead of a generic EPIPE. Signed-off-by:

Right now, the code that calculates alternate modes is not ready for devices with dual tuners. That's ok, as we currently don't have any such devices, but better to add a warning for such case, as, if anyone adds such device, the logic will need to be reviewed. Signed-off-by:

During the duplication of em28xx state for the second tuner pair a pointer to alt_max_pkt_size_isoc is copied. During tear down the second tuner is destroyed first and kfrees alt_max_pkt_size_isoc, then the first tuner is destroyed and kfrees it again. The property should only be kfree'd if the tuner is PRIMARY_TS. [ 354.888560] ------------[ cut here ]------------ [ 354.888562] kernel BUG at mm/slub.c:296!

Addresses the following, which introduced a regression itself: Commit 509f8965 ("media: em28xx: fix a regression with HVR-950") The regression fix breaks dual transport stream support. Currently, when a tuner starts streaming it sets alt mode on the USB interface. The problem is, in a dual tuner model, both tuners share the same USB interface, so when the second tuner becomes active and sets alt mode on the interface it kills streaming on the other port. This patch addresses the regression by only setting alt mode on the USB interface during em28xx_start_streaming, if the device is not a dual tuner model. This allows all older and single tuner devices to explicitly set alt mode during stream startup. Testers report both isoc and bulk DualHD models work correctly with the alt mode set only once, in em28xx_dvb_init. Fixes: 509f8965 ("media: em28xx: fix a regression with HVR-950") Signed-off-by:

This is implementing multi-stream decoder support. The multi-stream will be used to enable/disable the primary/secondary decoder outputs. Depending on formats on both decoder outputs we could implement downscale, dithering and supporting UBWC (universal bandwidth compression) formats. The UBWC compressed raw format is used to optimize interconnect bandwidth for bigger resolutions like 4K and hence we will get some power-saving benefits as well. Both decoder outputs are distinguished by buffer_type field in the HFI packets. For example HFI_BUFFER_OUTPUT is the buffer type for primary decoder output and HFI_BUFFER_OUTPUT2 is for secondary decoder output. Starting from Venus 4xx the DPB buffers format must be UBWC, so the multi-stream becomes mandatory for this Venus version. That means that we need to allocate internally in the driver a set of DPB buffers (with UBWC NV12 format) and give them to the firmware. The other decoder output (we called it OPB) format will be NV12 linear format and with the same resolution (or smaller in case the user wants to downscale). The DPB buffers are used for decoder reference frames and those have to be in a specific format (UBWC). So one decoder output is used to fill those reference buffers while the other output is used to fill the userspace buffers with the user requested format. Signed-off-by:
