Hi, I don't even know if NV supports it in HW, but seems Chinese GPUs yes.. https://www.phoronix.com/news/Moore-Threads-VA-API-FFmpeg and running vainfo can't see it:

vainfo: VA-API version: 1.20 (libva 2.12.0)
vainfo: Driver version: VA-API NVDEC driver [egl backend]
vainfo: Supported profile and entrypoints
      VAProfileMPEG2Simple            : VAEntrypointVLD
      VAProfileMPEG2Main              : VAEntrypointVLD
      VAProfileVC1Simple              : VAEntrypointVLD
      VAProfileVC1Main                : VAEntrypointVLD
      VAProfileVC1Advanced            : VAEntrypointVLD
      VAProfileH264Main               : VAEntrypointVLD
      VAProfileH264High               : VAEntrypointVLD
      VAProfileH264ConstrainedBaseline: VAEntrypointVLD
      VAProfileHEVCMain               : VAEntrypointVLD
      VAProfileVP8Version0_3          : VAEntrypointVLD
      VAProfileAV1Profile0            : VAEntrypointVLD
      VAProfileHEVCMain10             : VAEntrypointVLD
      VAProfileHEVCMain12             : VAEntrypointVLD

also FFMpeg supports decoding and encoding this profile from phoronix: https://github.com/FFmpeg/FFmpeg/commit/1cd5a383d49f94b05699b234b0d3c98f2969b810 https://github.com/FFmpeg/FFmpeg/commit/65e537b83379d2d6f87343f9bd59968b21d949a3

None of the main desktop gpu manufacturers support Hi10p and they never will - there was no commercial content and then hevc came along to become the standard.
