Subject: [PATCH v5 0/3] support of v4l2 encoder for STMicroelectronics SOC
Date: Mon, 29 Aug 2016 15:21:05 +0200	[thread overview]
Message-ID: <1472476868-10322-1-git-send-email-jean-christophe.trotin@st.com> (raw)

version 5:
- Compilation problem with 4.8-rc1 corrected: unsigned long used for dma_attrs
- The video bitrate (V4L2_CID_MPEG_VIDEO_BITRATE) and the CPB size (V4L2_CID_MPEG_VIDEO_H264_CPB_SIZE) were respectively considered in kbps and kb, while the V4L2 API specifies them in bps and kB. This is corrected and the code is now aligned with the V4L2 specification
- If the encoder close function (enc->close) has not been called through hva_stop_streaming (e.g. application is killed), it's called at the encoder instance release (hva_release)
- hva-v4l2.c: DEFAULT_* renamed HVA_DEFAULT_*
- hva-v4l2.c: few log messages modified
- typos corrected
- V4L2 compliance successfully passed with this version (see report below)

version 4:
- Module renamed "st-hva" as suggested by Hans
- resource_size() inline function used to calculate the esram size
- V4L2 compliance successfully passed with this version (see report below)

version 3:
- Comments from Nicolas, Javier and Hans about version 2 taken into account:
	- Kconfig's comment reworked
        - querycap: "driver" contains the name of the encoder ("hva"), "card" identifies the hardware version ("hva<hw_ip_version>" with <hw_ip_version> equal to 400 here, which leads to "hva400"), and "bus_info" indicates the location of the device ("platform:8c85000.hva")
	- device_caps field of struct video_device set to V4L2_CAP_STREAMING | V4L2_CAP_VIDEO_M2M
	- colorspace management aligned on the vim2m and mtk-vcodec drivers' code
	- useless debug messages removed
	- in case of error in start_streaming, all pending buffers for queue are returned to vb2 in the QUEUED state
	- hardware restriction with regards to the number of codec instances managed in start_streaming instead of open (then, the v4l2-compliance test for unlimited opens passes)
	- typos corrected
- V4L2 compliance successfully passed with this version (see report below)

version 2:
- List of pixel formats supported by the encoder reduced to NV12 and NV21
- x86_64 compilation warnings corrected
- V4L2 compliance successfully passed with this version (see report below)
- All remarks about version 1 of hva-v4l2.c taken into account:
        - V4L2 mem2mem framework used 
	- V4L2 control framework used
	- allocator context initialized in the probe and cleaned up in the remove
	- start_streaming and stop_streaming ops added
	- colorspace, bytesperline and sizeimage fields initialized in TRY_FMT
	- better estimation of sizeimage for compressed formats
	- checks and debugging logs already covered by vb2 removed
	- some dev_err changed in dev_dbg
	- typos corrected

version 1:
- Initial submission.

Only one feature supported and tested:
- encode (NV12, NV21) to H.264 video format

The driver is mainly implemented across three files:
- hva-v4l2.c
- hva-h264.c
- hva-hw.c
hva-v4l2.c manages the V4L2 interface with the userland.
It calls the HW services that are implemented in hva-hw.c.
hva-h264.c manages specific part of H.264 codec.

Below is the v4l2-compliance report for the version 5 of the hva driver:
