That doesn't impact what is measure by the Hantro hardware block itself. To give you an example that is the result of decoding one of the fluster reference file. gst-launch-1.0 filesrc location=AMP_A_Samsung_7.hevc ! h265parse ! v4l2slh265dec ! fakesink cat /sys/kernel/debug/tracing/trace # # entries-in-buffer/entries-written: 17/17 #P:4 # # _-----=> irqs-off # / _----=> need-resched # | / _---=> hardirq/softirq # || / _--=> preempt-depth # ||| / delay # TASK-PID CPU# |||| TIMESTAMP FUNCTION # | | | |||| | | <idle>-0 [000] d.h1 143.745124: hantro_hevc_perf: minor = 1, 180 cycles / mb <idle>-0 [000] d.h1 143.758086: hantro_hevc_perf: minor = 1, 172 cycles / mb <idle>-0 [000] d.h1 143.770829: hantro_hevc_perf: minor = 1, 167 cycles / mb <idle>-0 [000] d.h1 143.782757: hantro_hevc_perf: minor = 1, 166 cycles / mb <idle>-0 [000] d.h1 143.794866: hantro_hevc_perf: minor = 1, 165 cycles / mb <idle>-0 [000] d.h1 143.808012: hantro_hevc_perf: minor = 1, 165 cycles / mb <idle>-0 [000] d.h1 143.818225: hantro_hevc_perf: minor = 1, 166 cycles / mb <idle>-0 [000] d.h1 143.828063: hantro_hevc_perf: minor = 1, 165 cycles / mb <idle>-0 [000] d.h1 143.838217: hantro_hevc_perf: minor = 1, 165 cycles / mb <idle>-0 [000] d.h1 143.848728: hantro_hevc_perf: minor = 1, 172 cycles / mb <idle>-0 [000] d.h1 143.858677: hantro_hevc_perf: minor = 1, 167 cycles / mb <idle>-0 [000] d.h1 143.868576: hantro_hevc_perf: minor = 1, 166 cycles / mb <idle>-0 [000] d.h1 143.878431: hantro_hevc_perf: minor = 1, 165 cycles / mb <idle>-0 [000] d.h1 143.888684: hantro_hevc_perf: minor = 1, 165 cycles / mb <idle>-0 [000] d.h1 143.898827: hantro_hevc_perf: minor = 1, 166 cycles / mb <idle>-0 [000] d.h1 143.908645: hantro_hevc_perf: minor = 1, 165 cycles / mb <idle>-0 [000] d.h1 143.918772: hantro_hevc_perf: minor = 1, 165 cycles / mb > >> Patches 3 to 5 allow to decode and produce 10-bits P010 frames. > I suppose this means that some 10-bit test vectors in Fluster HEVC > test suite are now passing? > >> Patch 6 make usage of G2 post processor to scale down the frames. >> Patches 7 and 8 add the support of HEVC scaling matrix by adding a new >> control. >> > Ditto, the test vectors with scaling lists should now pass, any chance > you post the test suite run before and after this series, just for reference? Files like SLIST_A_Sony_5, SLIST_B_Sony_9, SLIST_C_Sony_4, SLIST_D_Sony_9 or DBLK_A_MAIN10_VIXS_4 are now decoded by the driver. fluster score is 70/147. I think it could be better but, in few cases, it seems that the last frames isn't retrieved by the userland stack but that need to be verify and debug in an other series ;-) Benjamin > > Thanks again, > Ezequiel > >> All these patches enhance the HEVC support for Hantro (G2) hardware. >> Unluckily they almost all touch the same pieces of code, where buffer >> size, offset and addresses are set, so they have to be in this order. >> They depend of the series pushed in this pull request: >> https://www.spinics.net/lists/linux-media/msg193744.html >> >> Benjamin >> >> Benjamin Gaignard (8): >> media: hantro: Trace hevc hw cycles performance register >> media: hantro: Add support of compressed reference buffers >> media: hantro: hevc: Allow 10-bits encoded streams >> media: Add P010 video format >> media: hantro: hevc: Allow to produce 10-bit frames >> media: hantro: enumerate scaled output formats >> media: hevc: Add scaling matrix control >> media: hantro: Add scaling lists feature >> >> .../media/v4l/ext-ctrls-codec.rst | 45 +++++ >> .../media/v4l/pixfmt-yuv-planar.rst | 8 + >> .../media/v4l/vidioc-queryctrl.rst | 6 + >> drivers/media/v4l2-core/v4l2-common.c | 1 + >> drivers/media/v4l2-core/v4l2-ctrls-core.c | 6 + >> drivers/media/v4l2-core/v4l2-ctrls-defs.c | 4 + >> drivers/media/v4l2-core/v4l2-ioctl.c | 1 + >> drivers/staging/media/hantro/hantro.h | 4 + >> drivers/staging/media/hantro/hantro_drv.c | 32 +++- >> .../staging/media/hantro/hantro_g2_hevc_dec.c | 175 ++++++++++++++++-- >> drivers/staging/media/hantro/hantro_g2_regs.h | 12 ++ >> drivers/staging/media/hantro/hantro_hevc.c | 60 +++++- >> drivers/staging/media/hantro/hantro_hw.h | 7 + >> drivers/staging/media/hantro/hantro_v4l2.c | 10 +- >> drivers/staging/media/hantro/imx8m_vpu_hw.c | 6 + >> drivers/staging/media/hantro/trace.h | 40 ++++ >> include/media/hevc-ctrls.h | 11 ++ >> include/uapi/linux/videodev2.h | 1 + >> 18 files changed, 407 insertions(+), 22 deletions(-) >> create mode 100644 drivers/staging/media/hantro/trace.h >> >
