Radeon RX 4XX/5XX standalone system, AMDRadeonX4250.kext (GVA support H264) does not support HEVC HW

[shuhung]

I put dummy kext in EFI/Clover/ketxs/Other but VideoProc freeze with H264/HEVC test. I need to do something more?

Thanks

VideoProc freeze on 10.14.1 is normal, same as my test, may be this is why RX4XX/5XX IOGVA/HEVC support has been suspended.

On 10.13.6, although test result is not as expect but GVA HEVC work, GVA H264 never work, png show HEVC work but GPU utilization is low.

Use Pacifist restore native AppleGVA.framework from OS installer is the best.
If manual replace AppleGVA.framework, should run below commands

cd /System/Library/PrivateFrameworks/
sudo codesign --deep -fs - AppleGVA.framework
sudo chown -R root:wheel AppleGVA.framework

Then update DYLD
sudo update_dyld_shared_cache -force

Sometime issue may caused by startup scripts or lockup by other apps, then may need attached utility for system cleanup/update cache.

I finally got it to work. I used the framework file you provided and manually installed it. I had to install Xcode to use the code sign command. The AppleGVA.Framework file you attached is from 10.14.1, correct?

Although on 10.14.2 beta, HEVC encode is must faster but still very unstable, should waiting for official release.
Recently, roll back to 10.13.6 seems to be the best choose, have better GVA support and system is much stable.

Since updating to Mojave official ( after 10.14 beta 3 ) I lost wake after sleep with my RX580 ( Kp upon wake with black screen ). Sleep was working fine before that, even with high sierra. Did anyone here crossed similar issue with their RX580? Probably the wrong thread for asking this, but i have looking for a solution for a while now, without success

Should return nothing, try manual install.

Sadly, with 10.14.1 AppleGVA.framework, my system is locking up when I use Photos app. The system is not completely frozen but it starts to lag severely. There's a delay in mouse cursor movement, switching between apps, opening new apps, etc. I had to move back to 10.14.0 AppleGVA.framework.

You can try this one (see attachment). Put these kext into /EFI/CLOVER/kext/Other.
Please note that for some applications, it could cause a kind of system-hangup, but in my case: iTunes, Safari+Netflix and AirPlay works flawlessly; For FCPX I need to disable this kext. As @shuhung said, looks like Apple has suspended the native hardware support for this kind of graphic card until resolve the application issues (in Mojave 10.14.0, full acceleration is OOB).

Regards.
