Some decoders and encoders can potentially have more than one source pad, so update the description to say 'at least one source pad'. 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:

Make a new function vdec_output_conf() for decoder output configuration. vdec_output_conf() will set properties via HFI interface related to the output configuration, and keep vdec_set_properties() which will set properties related to decoding parameters. Signed-off-by:

This adds suspend (power collapse) functionality by reusing the suspend function for Venus 3xx and also enables idle indicator property for Venus 4xx (where it is disabled by default). Signed-off-by:
-
Stanimir Varbanov authored
This moves setting of default properties (firmware debug, idle indicator and low power mode) from session init to core init. All of those properties are need to be enabled/disabled early so that they could be used before the clients are even initialized. The other reason is to set idle indicator property early before we enter into venus_suspend function where we need to check for ARM9 WFI. Signed-off-by:

This fixes the suspend function for Venus 3xx versions by add a check for WFI (wait for interrupt) bit. This bit is on when the ARM9 is idle and entered in low power mode. Signed-off-by:

Comparing an int to a size, which is unsigned, causes the int to become unsigned, giving the wrong result. kinect_read returns the result of usb_control_msg, which can return a negtive error code. A simplified version of the semantic match that finds this problem is as follows: (http://coccinelle.lip6.fr/) // <smpl> @@ int x; expression e,e1; identifier f; @@ *x = f(...); ... when != x = e1 when != if (x < 0 || ...) { ... return ...; } *x < sizeof(e) // </smpl> Signed-off-by:
