mainline kernel hardware acceleration
#21
linuxtv wip against media_tree master from linuxtv.org
drm next against next20200501 from kernel.org
ffmpeg v4l2 rkvdec against official 4.2.2

i made patchsets against next20200529 preparing for 5.7 to be released. (and prob slight changes afterwards). i was to share them when i get to my pbp (on phone now).

you are right that the patches didn't apply cleanly. i made several changes.

the kernel i am testing now, working well is:

next20200529
pinebookpro patch: https://pastebin.com/YK4LXeyv
LibreElec 1000 patch
v4l2 patch: https://pastebin.com/gaQSZQ6B
drm patch: https://pastebin.com/b1BWZ8Cg

plus:
ffmpeg 4.2.3 with v4l2-request-hwaccel-4.2.2-rkvdec patch: https://pastebin.com/uF5kpABD
kodi-git
libva-v4l2-request_master + pulls 29+30
libva_master + pulls 332+340
(for libva 332 delete the 5th chunk, version bump, or apply against libva 2.6.0)

general responsiveness is actually significantly better than 5.7-rc7 (!?), and my nvme drive is also much better handled. interesting.

also, i would recommend compiling hantro and rkvdec into the kernel, not modules, so that they are detected in the same order consistently.
