media: verisilicon: Fix IMX8 native pixel-format step values
The Hantro decoder non post-processed pixel-format steps are different
from the post-processed ones. Fix the steps according to the hardware
limitations. Since reference frame pixel-format issues have been fixed,
it is possible to use V4L2_PIX_FMT_NV15_4L4 rather V4L2_PIX_FMT_P010_4L4
for 10bit streams.
Fluster VP9 score goes up to 207/305.
HEVC score is still 141/147.

media: hantro: Disable multicore support
Avoid exposing equal Hantro video codecs to userspace. Equal video
codecs allow scheduling work between the cores. For that kernel support
is required, which does not yet exist. Until that is implemented avoid
exposing each core separately to userspace so that multicore can be
added in the future without breaking userspace ABI.
This was written with Rockchip RK3588 in mind (which has 4 Hantro H1
cores), but applies to all SoCs.

media: verisilicon: Add reference buffer compression feature
Reference frame compression is a feature added in the G2 decoder to
compress frame buffers so that the bandwidth of storing/loading
reference frames can be reduced, especially with high resolution decoded
streams.
The impact of compressed frames is confirmed when using perf to monitor
the number of memory accesses with or without the compression feature.
The following command:
perf stat -a -e \
imx8_ddr0/cycles/,imx8_ddr0/read-cycles/,imx8_ddr0/write-cycles/ \
gst-launch-1.0 filesrc \
location=Jockey_3840x2160_120fps_420_8bit_HEVC_RAW.hevc ! queue ! \
h265parse ! v4l2slh265dec ! video/x-raw,format=NV12 ! fakesink
Gives us these results without the compression feature:
Performance counter stats for 'system wide':
1711300345 imx8_ddr0/cycles/
892207924 imx8_ddr0/read-cycles/
1291785864 imx8_ddr0/write-cycles/
13.760048353 seconds time elapsed
With the compression feature:
Performance counter stats for 'system wide':
274526799 imx8_ddr0/cycles/
453120194 imx8_ddr0/read-cycles/
833391434 imx8_ddr0/write-cycles/
18.257831534 seconds time elapsed
As expected the number of read/write cycles are really lower when
compression is used.
Since storing the compression data requires more memory a module
parameter named 'hevc_use_compression' is used to enable/disable
this feature and, by default, compression isn't used.
Enabling the compression feature means that the output-frames of the
decoder
are stored with a specific compression pixel-format. Since this
pixel format is unknown, this patch restrains the compression feature
usage to the cases where post-processor pixel-formats (NV12 or NV15)
are selected by the applications.
The Fluster compliance HEVC test suite score is still 141/147 with this
patch.
