Re: 7800 XT extremely low FPS on fresh install [Solved]

Did you see the other two posts suggesting "amdgpu.ppfeaturemask=0xfffd3fff" and "amd_iommu=off amdgpu.mcbp=0 "?

Re: 7800 XT extremely low FPS on fresh install [Solved]

I now have

initcall_blacklist=simpledrm_platform_driver_init amdgpu.runpm=0 amdgpu.bapm=0 amdgpu.aspm=0 amdgpu.ppfeaturemask=0xfffd3fff amd_iommu=off amdgpu.mcbp=0 initcall_blacklist=simpledrm_platform_driver_init

I also have VT-d disabled in the BIOS

Boot with the intel GPU into linux-drm-tip-git and the amdgpu: [gfxhub] page fault errors have gone.

Re: 7800 XT extremely low FPS on fresh install [Solved]

Just realised my copy / paste must have got a bit excited and I have initcall_blacklist=simpledrm_platform_driver_init twice.  Don't think that matters, please correct me if I'm wrong

Re: 7800 XT extremely low FPS on fresh install [Solved]

You can add this as many times as you want. To be sure you can check the system journal whether the simpledrm device still shows up, but it won't.

Still no help on up-clocking the GPU? I guess.

Only the disconnected DP-1-2, DP-1-3,  HDMI-1-2 and HDMI-1-3 have prime sync attributes - it seems it's only available for outputs that are not attached to the main GPU (for regular reverse prime)
So that's a dead end either

DP-1-2, DP-1-3,  HDMI-1-2 and HDMI-1-3 could well be the usb-c connections, what do you think?

Re: 7800 XT extremely low FPS on fresh install [Solved]

Just found this - some guy is running a NVIDIA 4090 under Rocky Linux 8.5.  Going to try Rocky Linux USB, I've not tried any RPM based Linux yet.  Not holding out a lot of hope

Re: 7800 XT extremely low FPS on fresh install [Solved]

Tried Rocky 9 live but it came with 5.14 which doesn't have 7800 XT support.  Installed on the thumb drive and updated to 6.6 but it was full of amdgpu errors so gave up with it

Decided to try Fedora 39 on the thumb drive.  That came with 6.5.11-300.fc39.x86_64 and gave me the same results.  Updated to 6.7.0-0.rc1.20231119gt037266a5.320.vanilla.fc39.x86_64, same results

Also tried Tumbleweed.  Same results with both 6.6.1-1-default and 6.7~rc1-2.1.g86e46c2

Re: 7800 XT extremely low FPS on fresh install [Solved]

Remembered that overclocking with AMD Navi 31/32/33 will not work until kernel 6.7 at the earliest

Installed 6.7.0-rc3-1-mainline from miffe

Added amdgpu.ppfeaturemask=0xffffffff

CoreCtrl works!

If I set Performance mode to Advanced and change nothing else the GPU memory finally rises above 96Mhz in the benchmark

The result isn't great but it's a step in the right direction

Nearly the same situation here (NUC13RNGi7 + RX 7900 XT)! Thus, waiting for Kernel 6.7.* is the only solution for now?

Regarding your The i7-13700K. On Linux there is no prioritization for the p-cores and e-cores. This messed up my game performance. Disable all e-cores in BIOS.

6.7.0-rc4-1-mainline seemed to regress but 6.7.0-rc5-1-mainline is working again, although I'm still not getting anywhere near what I was getting on my old 4790k

Thanks for the information.  I've just tried with all e cores disabled and all e and p cores enabled.  As you can see I'm getting very slightly better results with all cores enabled

6.7.0-rc5-1-mainline is giving better results than 6.7.0-rc3-1-mainline so it looks to be moving in the right direction but it's still not fixed

Re: 7800 XT extremely low FPS on fresh install [Solved]

I seemed to have missed the 6.7.0-rc6-1-mainline release but 6.7.0-rc7-1-mainline gives me this which is another step backwards

Re: 7800 XT extremely low FPS on fresh install [Solved]

That's a really informative benchmark result /sarcasm.
From the looks I'd say it actually ran on the IGP ("Driver: i915")?

Re: 7800 XT extremely low FPS on fresh install [Solved]

nvtop shows me it's running on the amd gpu

The benchmark may not be the best but it's all I have to gauge any progress made in 6.7.  If there's something better I'm open to suggestions.  I'm gradually losing hope for 6.7 getting anywhere near fixing this

Re: 7800 XT extremely low FPS on fresh install [Solved]

https://wiki.archlinux.org/title/Benchmarking#Graphics
Are the results w/ the previous rc reproducible (to rule out flukes)?
If so it'd be rather easy to bisect the offending commit and file a bug, fixing by hope it will probably not.

Re: 7800 XT extremely low FPS on fresh install [Solved]

All of the rcs are giving results in the same range and the differences could easily be flukes

Not one single rc has yet given a result more than 20% of what I obtained by moving the drive and gpu to my old 4790k or from running Windows on this machine.  At the same time there's a definite improvement over 6.6

I've just tried rc8 with almost the exact same results as rc7

Still the gpu is working similar to 6.6 with the mem stuck at 97Mhz (depending on monitor refresh rate).  With the 6.7rcs this is the same until I increase the min mem MHz in CoreCtrl from 97 to 98 (or anything).  After that I am able to reset CoreCtrl to default and the mem in nvtop increases above 97Mhz when the benchmark is running

I already have a bug report open here but it's not going anywhere so I'm left with documenting my results

I have no experience bisecting

Re: 7800 XT extremely low FPS on fresh install [Solved]

https://wiki.archlinux.org/title/Bisect … s_with_Git - but if it's not a regression and/or there's no reliable test of the impact, that's moot.

If I set Performance mode to Advanced and change nothing else the GPU memory finally rises above 96Mhz in the benchmark

slightly spins up mclk

$ cat /sys/class/drm/card1/device/pp_dpm_mclk
0: 96Mhz 
1: 456Mhz *
2: 772Mhz 
3: 1249Mhz
$ cat /sys/class/drm/card1/device/pp_dpm_sclk
0: 500Mhz
1: 10Mhz *
2: 2025Mhz

but the performance still sucks badly

Is the change likelwise (30%/50%) limited for you?

Re: 7800 XT extremely low FPS on fresh install [Solved]

Looks like mainline has gone stable now - 6.7-1

Will test as soon as I can, time poor at the moment

Now using 6.7.0-arch3-1

I'm stuck at around 20% of what I'd expect from testing with Windows and my old 4th gen i7

Mem still stuck at 96MHz

cat pp_dpm_mclk

1: 456Mhz 
2: 772Mhz 
3: 1218Mhz 

echo "3" > pp_dpm_mclk

cat pp_dpm_mclk

0: 96Mhz *
1: 456Mhz 
2: 772Mhz 
3: 1218Mhz 

Still stuck at 96Mhz in the benchmark

corectrl 1.3.9-1

Set performance mode to Advanced

Increase Memory minimum from 97 to 98 and apply (not sure why that's 97 not 96)

Memory is now no longer stuck at 96Mhz in the benchmark.  However performance is ~20% of expected

In corectrl choose Reset - "Do you want to load the default settings" - Yes

Performance mode is now set to Automatic again and the mem is not stuck at 96Mhz in the benchmark.  Performance is ~20% of expected

Re: 7800 XT extremely low FPS on fresh install [Solved]

This is what I'm getting in the benchmark now, nowhere near what I got on my 4th gen i7

Re: 7800 XT extremely low FPS on fresh install [Solved]

Your 4th gen i7 uses a hybrid graphics setup where superposition runs on the intel i915 driver.

The current setup is not a hybrid setup (either the cpu has no internal intel graphics or they are disabled) and runs superpostion on the amdgpu driver.

Please stop comparing oranges to pears.

Disliking systemd intensely, but not satisfied with alternatives so focusing on taming systemd.

clean chroot building not flexible enough ?
Try clean chroot manager by graysky

Re: 7800 XT extremely low FPS on fresh install [Solved]

I had a very similar, although slightly higher, result running Windows on my current machine to what the 4th Gen i7 achieved

Both had results in the same region as the phoronix article so I presume the GPU works as it should in those situations
