[PATCH v3 0/9] Qualcomm video decoder/encoder driver

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi,

Here is v3 of the Venus v4l2 video encoder/decoder driver.

The changes since v2 are:
	- return queued buffers on stream_on error.
	- changed name of the driver vidc -> venus and reflect that in
querycap.
	- fix video_device::release to point to video_device_release.
	- tried to implement correctly g_selection for decoder and encoder.
	- added Venus HFI 3xx basic support, to able to reuse driver on
msm8996.
	- extend DT binding with reg-names and interrupt-names.
	- parse DT IRQ and MEM resources by name.
	- merge hfi_core,hfi_inst in venus_core and venus_inst structures.
	- killed hfi_pkt_ops struct and use functions.
	- various cleanups.

The output of v4l2-compliance looks like:
