[PATCH v12, 00/17] media: mtk-vcodec: support for M8192 decoder

[Yunfei Dong]

This series adds support for mt8192 h264/vp8/vp9 decoder drivers. Firstly, refactor
power/clock/interrupt interfaces for mt8192 is lat and core architecture.

Secondly, add new functions to get frame buffer size and resolution according
to decoder capability from scp side. Then add callback function to get/put
capture buffer in order to enable lat and core decoder in parallel, need to
adjust GStreamer at the same time. 

Then add to support MT21C compressed mode and fix v4l2-compliance fail.

Next, extract H264 request api driver to let mt8183 and mt8192 use the same
code, and adds mt8192 frame based h264 driver for stateless decoder.

Lastly, add vp8 and vp9 stateless decoder drivers.

Patches 1 refactor power/clock/interrupt interface.
Patches 2~4 get frame buffer size and resolution according to decoder capability.
Patches 5 set capture queue bytesused.
Patches 6 adjust GStreamer.
Patch 7~11 add to support MT21C compressed mode and fix v4l2-compliance fail.
patch 12 record capture queue format type.
Patch 13~14 extract h264 driver and add mt8192 frame based driver for h264 decoder.
Patch 15~16 add vp8 and vp9 stateless decoder drivers.
Patch 17 prevent kernel crash when rmmod mtk-vcodec-dec.ko

[PATCH v12, 02/17] media: mediatek: vcodec: Using firmware type to separate different firmware architecture

[Yunfei Dong]

MT8173 platform use vpu firmware, mt8183/mt8192 will use scp
firmware instead, using chip name is not reasonable to separate
different firmware architecture. Using firmware type is much better.

[PATCH v12, 05/17] media: mediatek: vcodec: set each plane bytesused in buf prepare

[Yunfei Dong]

call vb2_set_plane_payload to set each plane bytesused in buf prepare,
need not to set independently for stateless and statefull architectures.

[PATCH v12, 06/17] media: mediatek: vcodec: Refactor get and put capture buffer flow

[Yunfei Dong]

For lat and core decode in parallel, need to get capture buffer
when core start to decode and put capture buffer to display
list when core decode done.

[PATCH v12, 12/17] media: mediatek: vcodec: record capture queue format type

[Yunfei Dong]

The capture queue format type may be differ depending on platform: for
stateless decoder drivers, we need to calculate the capture buffer size
according to the capture queue format type in SCP.

As a preparation for introducing drivers for stateless decoding, save the
current capture queue type on a per vcodec context basis.

Here there is still a cast to iomem:

but that function was moved (AFAICT) from vdec_h264_req_if.c where a regular memcpy was
used.

Did you miss one iomem case?

Can I change mtk_vdec_h264_copy_scaling_matrix() to:

void mtk_vdec_h264_copy_scaling_matrix(struct slice_api_h264_scaling_matrix *dst_matrix,
				       const struct v4l2_ctrl_h264_scaling_matrix *src_matrix)
{
	memcpy(dst_matrix->scaling_list_4x4, src_matrix->scaling_list_4x4,
	       sizeof(dst_matrix->scaling_list_4x4));

	memcpy(dst_matrix->scaling_list_8x8, src_matrix->scaling_list_8x8,
	       sizeof(dst_matrix->scaling_list_8x8));
}

If that's OK, then I'll do that manually, so no need to post a v13.

Everything else looks fine, so this is the only issue that needs to be resolved.

Regards,

	Hans

1: For h264_req_if.c no need to add __iomem anymore. You can help to
change it directly.

2: Could you please help to add for whole series: Tested-by: Nícolas F.
R. A. Prado <nfraprado@collabora.com>

according to Nicolas's mail.

Hi Yunfei,

With this series, and the new scp.img for mt8192 [1] (still waiting to
get
merged), I was able to get the following fluster scores on
mt8192-asurada-spherion:

VP8: 59/61
VP9: 249/303
H.264: 92/135

So for the whole series:

Adds h264 lat and core architecture driver for mt8192,
and the decode mode is frame based for stateless decoder.

[PATCH v12, 16/17] media: mediatek: vcodec: support stateless VP9 decoding

[Yunfei Dong]

Add support for VP9 decoding using the stateless API,
as supported by MT8192. And the drivers is lat and core architecture.

[PATCH v12, 17/17] media: mediatek: vcodec: prevent kernel crash when rmmod mtk-vcodec-dec.ko

[Yunfei Dong]

If the driver support subdev mode, the parameter "dev->pm.dev" will be
NULL in mtk_vcodec_dec_remove. Kernel will crash when try to rmmod
mtk-vcodec-dec.ko.

Hi Yunfei,

With this series, and the new scp.img for mt8192 [1] (still waiting to get
merged), I was able to get the following fluster scores on
mt8192-asurada-spherion:

VP8: 59/61
VP9: 249/303
H.264: 92/135

So for the whole series:

Thanks,
