MP 1,1-5,1 Activate AMD hardware acceleration

[Ausdauersportler]

Seems I've lost HW video acceleration even though VideoProc says H264 and HEVC HW support is detected and enabled. I've gone from 180-220 FPS to 50-55 FPS when converting a 1080p MKV to a 720p HEVC MP4. That number remains the same whether or not HW acceleration is enabled in VideoProc.

Only thing that's changed since the last time I converted something was installing the supplemental update to SU2021-002.

OpenCore is running:

Also confirmed via iStat that GPU isn't getting loaded at all. At least when HW encoding was working at ~200fps, I'd see a load of roughly 3% on the Vega 64.

Any suggestions on what to do / look for?

EDIT: I just remembered. Also updated OC to v0.6.6 about a week ago which in turn updated LiLu and Weg

Recently I came across the free app for the Appstore named "Blackmagic RAW Speed Test". It just tests the video encoding features of the GPU and CPU and is helpful to cross check.

Thanks, I'll check that out. Good to have something to cross-validate.

Uh...maybe I did something terrible wrong, with my Sapphire Puls RX580, I get just only a black screen.

 

[Fawzi]

Upgraded my old 2009 4,1 flashed to 5,1 MP with a Geforce GT640 to Big Sur. Worked like magic !
This is my home server machine that I run headless. It runs Plex, Channels DVR, FTP server, WebDav server, printer server and content caching.
It's a bit Frankesteined with HDDs in place of the optical drives, internal RAIDS and a small SSD for the system and apps. I just wanted it to remain compatible with the other (more recent) Macs I use at home.
I had to manually enable WiFi (as per the instructions) and the connection to one of my WiFi AP is still a bit finicky but to my old Airport Extreme it works fine and even so I seldom use it.

Thank you so much for giving a new lease on life to this old faithful. It's good for the planet. And it's good for the geek. Can't ask for more ! 😊

It's good for the planet? That's debatable considering the energy efficiency of these old Mac Pros lol

As we do not know the real climate bill associated with each new industrial good and since at least in Germany the rate of natural power (photovoltaics and wind) is rising fast I would say stick with old gear if it suits your needs and you are able Pay the energy bill. It is debatable...

I read a few pages of this thread looking for answers, but just came across people arguing about it. I have a radeon 7970; is h264 hardware encoding/decoding possible with opencore?

Post #1 question 9 says the 7950 doesn’t work and the 7970 uses the same Tahati core. I believe Polaris are the earliest supported Radeon cards.

 

[amstel78]

The following issue is purely cosmetic, but just thought I should make all aware. When adding a device name for your GPU to OC's config.plist, it no longer works with OC v0.6.7. Despite the entry being there, VideoProc now returns GPU N/A or something to that effect.

Config file from OC v0.6.6 on the left and 0.6.7 on the right.

 

[tsialex]

Post #1 question 9 says the 7950 doesn’t work and the 7970 uses the same Tahati core. I believe Polaris are the earliest supported Radeon cards.

The API that provides hardware encoding and decoding acceleration is VideoToolbox.

The first Mac GPU that have VideoToolbox support is the mobile versions of RX 380, so you can get hardware encoding and decoding acceleration via VideoToolbox API enabled with any AMD GPU later than that.

Hi Martin,

I installed your latest (0.6.7) package and made some personal adjustments - 10 Min. later I reboot and be ready. Your work is amazing - I had seen that a lot of improvements go from the discussion thread right into the config file. 👍

Thank you for your work on that great project - 2nd donation is on the way. Stay healthy.

Installed a new wifi card on my 5.1, had to do a PRAM reset and lost my h264 hw accel. I did the terminal command from step 14 again (lilu method) and still not working. Using a vega56 on last mojave... any ideas? Should I redo the whole procedure again?

And boot to recovery partition to disable SIP. Otherwise, 3rd party kext won't load.

forgot to mention that, I've booted into recovery, disabled SIP successfully, rebooted, entered the terminal command step 14 and no luck

If not sure which part goes wrong. Then simply re-do the whole procedure should be easier.

The whole thing can be done within 10 min.

got it working by repeating steps 9-14. cheers!

 

[jeff_123450]

I created a new "easy to install package" as per many requested (based on the official OpenCore). [The attached package already updated to 0.6.7]

For those who only need HWAccel, post #594 has everything you need. This new package mainly offer HWAccel + boot screen. Also, this package should work in Catalina for dual processor cMP.

I don't mind you guys discuss anything about this package, but I have no plan to provide any explanation about OpenCore at here. If you want to know more, please join cdf's OpenCore thread. For new joiners, please make sure read through the FAQ in post #1 before you ask anything.

The attached packaged included Clover Configurator and a complete preconfigured OpenCore. All credits goes to the developer teams. If you want to show your support, please give them donation (declaration of interest： I am NOT in any of their developer teams)

For Clover Configurator and OpenCore developers teams, please let me know if you want me to remove the associated software inside my attachment in this post.

This is a "one package fit all" solution. So, it's designed to fit as much setup as possible, which may not be optimised for your setup (e.g. I did't provide HiDPI boot screen, for those who are running 4K screen, the Apple logo may be quite small during boot). You have to do the optimisation by yourself (details in the OpenCore manual, some info also available in cdf's OpenCore thread).

Anyway, for those who have RX 460 or newer AMD GPU, this package should gives you:

1. Boot screen (via GOP for unflashed card, including some Nvidia card)
2. Firmware protection (to run Windows in EFI mode without risking the cMP bootROM)
3. HWAccel (H264 / HEVC hardware decode + encode in Mojave or later)
4. ability to watch DRM streaming content (Mojave and later)
5. Boot picker (only support EFI systems, tested with Apple wired keyboard, Magic Mouse, and Magic Keyboard, 10s timeout. If you can't see this. Just don't touch the keyboard, and your cMP should continue to boot to desktop)
6. NVMe and SATA drives on PCIe card show up as internal
7. Support for Apple USB SuperDrive
8. TRIM (regardless trimforce status)
9. Ability to run non-GUI 32bit software in Catalina
10. Ability to reset NVRAM in boot picker (disabled at this moment to align with the native Apple boot manager)
11. Ability to run any natively supported ancient OSX with modern graphic card e.g. Radeon VII in 10.6.8 (only can display, no acceleration) [Update 5th May 2020: Sierra and High Sierra may not fully supported yet. Thanks for pierrox's report]
12. Ability to boot Catalina / Big Sur Recovery Partition
13. Sleep should work (tested on my cMP, but I can't guarantee it also work with your hardware)
14. Possible to run 8x32GB RAM in macOS

It's impossible for me to test every single function in all situations. So, as usual, use at your own risk. But you are welcome to report back if there is any problem / error.

Pre-installation:

• Recommend to backup your BootROM between step 1 and 2 (e.g. by using ROMTool)
• If you want to test OpenCore, you can install this package onto a bootable USB thumb drive.
• Quite a few users reported that can't boot OpenCore from NVMe, please avoid to install this package on NVMe. You can install this package on ANY SATA drive, not necessary your boot drive.
• If you want to remove OpenCore, please mount the EFI partition by using Clover Configurator, then remove BOOT and OC folders inside the EFI folder on EFI partition.
• If your cMP stuck at boot. After shutdown, please pull out the hard drive that contain OpenCore, then perform NVRAM reset. If still doesn't work, then please install your emergency graphic card that has boot screen. Hold Option to boot, then select your backup boot drive. This should disable OpenCore.
• For those who want to report issue / error. Please provide details (e.g. which graphic card, OpenCore installed on NVMe / SATA drive, the issue's details, etc) otherwise it will be extremely hard (or even impossible) for me to work out what's wrong.
• If you installed Lilu for whatever reason (e.g. because of innie), or applied my previous non-OpenCore HWAccel mod, please remove them or revert them. For Lilu + WEG, that means delete Lilu.kext in /Library/Extensions/ and reboot (caution: these kexts may be installed in System/Library/Extensions/ as well). For hex edit method, that means delete AppleGVA.framework in /System/Library/PrivateFrameworks/ and rename AppleGVA.framework.bak to AppleGVA.framework. Warning: My package already have Lilu and WEG included, "double installation" of these kexts will cause macOS boot failure.
• For PULSE RX580, users reported that only can see boot screen when boot from gaming mode. There may be no UEFI GOP in the compute mode's ROM.

Anyway, I tried to make the installation as simple as possible. Here is what you need to do

1. [Optional] 3x NVRAM reset to avoid some unknown issues.
2. Disable SIP (must do, especially if you performed step 1)
3. Download the attachment in this post (Some users reported 0.6.1 package has compatibility issue. You may download the 0.5.9 package if you prefer that, same installation procedures)
4. Follow the steps in this video
   
5. Spoiler: Multi monitors fix for Big Sur

   For Big Sur only, if some ports on your graphic card are disabled, please follow the steps in this video to re-enable them.
   
6. Reboot

For existing OpenCore users, you may follow the step in this video to update OpenCore

Additional option 1: If you have 4K screen, and you want to have "Retina" boot screen. You may do this.

Additional option 2: If you have a flashed Thunderbolt 3 card, you can install that in slot 4, then enable Thunderbolt 3 support by doing this.

Additional option 3: If you want to enable the ability to install / update Catalina [Update: Thanks for cdf's finding. If you are with the 0.6.3 (and newer) package, and want to install Big Sur, your 5,1 should able to do that "natively". No need to touch the VMM flag etc]

Additional option 4: If you have legacy wifi card, you may try the follow steps to re-activate the old wifi card in Big Sur (only avail in my 0.6.4 package or above)

Additional option 5: Since 0.6.3, I allow OC to take over SIP control. There are various reasons, but anyway, that's default to be disabled. If you want to re-enable SIP, please follow the steps in this video.

For FCP(X) users, if you want to export HEVC video by using HWAccel, you will need Compressor.
[N.B. The setting MUST identical to the one that I show in the video. Otherwise, HEVC hardware encoding may not work]

If you want to completely uninstall my OpenCore package, please follow the steps in this video.

N.B. Unflashed graphic card means "the ROM is never modified". For those who bought used card, and can't see the boot screen, most likely the last user flashed the card with modified ROM (e.g. downvolt for mining). In this case, you can go to TechPowerUp to find a ROM that fit your own card, and flash it.

I got this going no problem. Works great. One thing I'm having trouble with is NVRAM reset. Everytime I do one I have to rebless my EFI partition. Is there a way to get NVRAM resets going without having to rebless?

 

[sunsea]

Hi, just upgraded OC to 0.6.7 on CMP5.1 (updated BigSur to 11.2.2), only changed the Retina option in config.plist. Have a keyboard/mouse issue.
If I cold boot, and don't hit any key, then keyboard and mouse are ok. If in the bootloader menu I try to change boot target (right/left key on keyboard), nothing happens and the keyboard will not work once booted. Even after reboot, it will not work. Need to shutdown and cold start again.

Any idea ?

thanks !

Check your BootROM, possible multiple BT config stored in the NVRAM.

Hi, thanks for your help ... but I don't know how to check that. Or do I need to clear the NVRAM ? I don't have a mac flashed bios GPU so I can't see the normal MAC bootscreen... Any article/post to point me to ?

ok, after changing also the csr-active-config to FF0F0000 ( on top of changing the UIScale to retina) in your config.plist provided with OC 0.6.7, everything is working well again. Keyboard and mouse worked again before the csr-config-changes (needed a couple of reboot/ cold starts --- mystery of IT), but handoff was not working for example and changing csr-active-config fixed it. Thanks anyway for your help and thanks for packaging OC so that it is so simple to update of cmp5.1 ! Cheers !

Additional option 2: If you have a flashed Thunderbolt 3 card, you can install that in slot 4, then enable Thunderbolt 3 support by doing this.

Additional option 3: If you want to enable the ability to install / update Catalina [Update: Thanks for cdf's finding. If you are with the 0.6.3 (and newer) package, and want to install Big Sur, your 5,1 should able to do that "natively". No need to touch the VMM flag etc]

Additional option 4: If you have legacy wifi card, you may try the follow steps to re-activate the old wifi card in Big Sur (only avail in my 0.6.4 package or above)

Additional option 5: Since 0.6.3, I allow OC to take over SIP control. There are various reasons, but anyway, that's default to be disabled. If you want to re-enable SIP, please follow the steps in this video.

For FCP(X) users, if you want to export HEVC video by using HWAccel, you will need Compressor.
[N.B. The setting MUST identical to the one that I show in the video. Otherwise, HEVC hardware encoding may not work]

If you want to completely uninstall my OpenCore package, please follow the steps in this video.

N.B. Unflashed graphic card means "the ROM is never modified". For those who bought used card, and can't see the boot screen, most likely the last user flashed the card with modified ROM (e.g. downvolt for mining). In this case, you can go to TechPowerUp to find a ROM that fit your own card, and flash it.

[Last update: 3 Mar 2021, OC 0.6.7, Lilu 1.5.1, WEG 1.4.8]

In your readme.txt, at the "Installation / update" section, you say:
For those who already have UEFI Windows installed, you may consider to install OpenCore onto the Windows drive's EFI partition. In order to do that, after mount the EFI partition, you should
1) rename the NO NAME partition to EFI
2) keep the Microsoft folder
3) replace the Boot folder
4) install the OC folder
So, now I have the OC installed in the EFI partition of another drive SATA (reloading the backup EFI folder with OC 0.6.6) and I can no longer see the Windows disk (icon) at startup (boot picker) of OC.
I can't figure out what I'm doing wrong!
Before I tried to do the OC update I could boot Windows and now, even having reinstalled the previous version, there is no longer a Windows icon so I can't boot it!
I ask you to please help me! Thank you!

I did the upgrade with your package OC 0.6.7 (I have Mojave in SATA, Big Sur in NVMe, OC in SATA and Windows in SATA).
Unfortunately, when I reboot I don't see the Windows volume anymore!
I then uninstalled OC, removed the Windows disk, and reinstalled OC 0.6.6 (backup).
I reinserted the Windows disk, but I still can't see the Windows volume icon at startup!
I am asking for your help on how to restore OC and Windows!
Thanks in advance!

Can you select Windows in system preferences -> startup disk (with OC installed)?
