Bug ID: 86891 Summary: AMD/ATI Tahiti XT 7970 - long lags/stutters in games Product: Drivers Version: 2.5 Kernel Version: >=3.17 until 3.18rc1 Hardware: All OS: Linux Tree: Mainline Status: NEW Severity: high Priority: P1 Component: Video(DRI - non Intel) Assignee: drivers_video-dri@kernel-bugs.osdl.org Reporter: bu9zilla@gmail.com Regression: No
Created attachment 155001 --> https://bugzilla.kernel.org/attachment.cgi?id=155001&action=edit Kernel config of 3.18rc1
Since kernel Version 3.17 and greater (last tested with kernel-3.18rc1) i'm encounter very long stutters/lags (1-2sec) when i'm gaming various games. (eg borderlands2)
Usually i'm doing a unigine valley benchmark test after i install a new kernel to see how much more performance i get and usually the benchmarks are very promising. (FPS continuous rises) :) However since kernel-3.17 i get really long stutters/lags in my tests. FPS doesn't really go done, they rise even more (max fps), but i also always get really serious stutters, where i have to wait about 1-2 sec until the graphic's continue to render. This is really annoying.
Besides getting higher max fps in Unigine i also get new lowest min fps. Below a short overview of my benchmark tests (with date):
Linux 3.16.2-gentoo x86_64 - 20140914 FPS: 17.4 Score: 727 Min FPS: 8.2 Max FPS: 28.1
Linux 3.17.0-rc6 x86_64 - 20140927 FPS: 16.2 Score: 680 Min FPS: 4.2 Max FPS: 32.1
Linux 3.18.0-rc1 x86_64 - 20141025 FPS: 15.9 Score: 666 Min FPS: 3.2 Max FPS: 34.4
Today's test (same software stack, just different kernels)
Linux 3.18.0-rc1 x86_64 Linux 3.16.3-gentoo x86_64 FPS: 15.9 18.7 Score: 666 782 Min FPS: 3.2 8.3 Max FPS: 34.4 30.5
Usually downgrading to kernel-3.16 always solves the problem for me which is why i think the problem has todo with the kernel side of the ati driver.
I've also tried the new firmware blobs for my graphics card (TAHITI_ce.bin -> tahiti_ce.bin, ...), they didn't make any differences.

Sure, give me some days - i'll try to bisect the problem. :) Guess it will take some time, since there were many commits between 3.16 and 3.17rc1.
I'll take the kernel git tree for the bisect (git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git) and bisect between 3.16rc8 and 3.17rc1.
As soon as i have some result's i'll gonna update this bug.

The result:
59bc1d89d6a4d67c94a9b70fa81bda1d5b04f0cb is the first bad commit commit 59bc1d89d6a4d67c94a9b70fa81bda1d5b04f0cb Author: Lauri Kasanen cand@gmx.com Date: Sun Apr 20 20:29:33 2014 +0300
drm/radeon: Inline r100_mm_rreg, -wreg, v3
This was originally un-inlined by Andi Kleen in 2011 citing size concerns. Indeed, a first attempt at inlining it grew radeon.ko by 7%.
However, 2% of cpu is spent in this function. Simply inlining it gave 1% more fps in Urban Terror.
v2: We know the minimum MMIO size. Adding it to the if allows the compiler to optimize the branch out, improving both performance and size.
The v2 patch decreases radeon.ko size by 2%. I didn't re-benchmark, but common sense says perf is now more than 1% better.
v3: Also change _wreg, make the threshold a define.
Inlining _wreg increased the size a bit compared to v2, so now radeon.ko is only 1% smaller.

Additional all benchmarks i've made from every bisected kernel. the first one is the 3.16rc7 benchmark, the second the 3.17rc1. The others are from the bisected kernels.
You'll see on the benchmarks it always has a difference of about 100 points (good vs bad), which is about 10% performance difference.

I've tried it with kernel git 3.18rc2 with a pull a few minutes ago and with `git revert 59bc1d8`. The result looks promising. I've made two benchmarks:
1st 2nd FPS: 18.3 18.1 Score: 765 757 Min FPS: 5.9 6.3 Max FPS: 32.4 31.9
I didn't include drm-next simply because i don't know how todo that. :) If you want me to test drm-next as well please point me to some documentation how to include it. :)

Yes, looks much better, but the code shouldn't touch any relevant (radeonsi/r600g) code paths. - Michel?
On r600g (RV730 AGP) I do NOT see any (real) change with this revert... Maybe we do not hit the real BAD commit.

Alex's drm-next-3.19-wip (it shows 3.17-rc5 ;-) for example: git clone git://people.freedesktop.org/~agd5f/linux/ drm-next-3.19-wip
If you have it already, get it or change it to another tree: cd drm-next-3.19-wip git checkout -b drm-next-3.19-wip remotes/origin/drm-next-3.19-wip
Sometimes you need this: git fetch origin git reset --hard origin/drm-next-3.19-wip

I'll get slightly better results with 10.3.2 (with 3.18rc1): FPS: 16.6 Score: 694 Min FPS: 3.7 Max FPS: 33.1
But honestly, watching the demo feels like it got even worse. Still very long lag's, especially at the beginning of new scene's (before it starts to render).

Alex's drm-next-3.19-wip (it shows 3.17-rc5 ;-) for example: git clone git://people.freedesktop.org/~agd5f/linux/ drm-next-3.19-wip
If you have it already, get it or change it to another tree: cd drm-next-3.19-wip git checkout -b drm-next-3.19-wip remotes/origin/drm-next-3.19-wip
Sometimes you need this: git fetch origin git reset --hard origin/drm-next-3.19-wip
I've just started cloning drm-next-3.19 but freedesktop seems to be quite slow - looks like i can start testing it tomorrow :/

Don't know if this helps but i just saw that i got strange (?) output in dmesg. This output showed up about 20min after i made that benchmark mentioned before (mesa-10.3.2/kernel-3.18rc1). As far as i can remember i didn't do anything specific that moment - just internet surfing.

I'll get slightly better results with 10.3.2 (with 3.18rc1):

But honestly, watching the demo feels like it got even worse. Still very long lag's, especially at the beginning of new scene's (before it starts to render).
Weird, it seemed to help a lot for myself and many others. Any chance you could try current Mesa Git master?
Can you create a screenshot from running with GALLIUM_HUD and showing the graphs corresponding to a lag, such as in https://bugs.freedesktop.org/show_bug.cgi?id=84570 ?

--- Comment #14 from Michael Mair-Keimberger bu9zilla@gmail.com --- OK, today i made another benchmarks: drm-next, mesa-10.3.2. First without any changes, second with `git revert 59bc1d8`:
without any changes with `git revert 59bc1d8` FPS: 14.3 19.1 Score: 599 801 Min FPS: 2.1 12.2 Max FPS: 30.7 30.7
Honestly, the difference is incredible. Can't believe such a small change has such a big impact. It even seems with the commit the performance get's worse over time - never had under 600 points before..
@Michel: mesa-10.3.2 does indeed help. I already had minor lag's/stutters in the past (pre-3.17) - that was "normal" for me, but now i have ZERO lags. The complete benchmark was done without one major lag. AWESOME :)
If anyone is interested i can also create videos, so you can see the differences :)

I've made a few other benchmarks and tried to take some screenshots. Unfortunately vally doesn't include GALLIUM_HUD when i'm taking screenshot's. As a workaround i've made photos with my mobile. Hope that's ok :)
On a side-note: I've got other kernel msg's with the unchanged kernel. Don't know if it's relevant but it looks like that:
[ 2915.586345] radeon 0000:01:00.0: GPU fault detected: 146 0x00139004 [ 2915.586350] radeon 0000:01:00.0: VM_CONTEXT1_PROTECTION_FAULT_ADDR 0x00004B00 [ 2915.586353] radeon 0000:01:00.0: VM_CONTEXT1_PROTECTION_FAULT_STATUS 0x13090004 [ 2915.586357] VM fault (0x04, vmid 9) at page 19200, write from CB (144) [ 2915.586362] radeon 0000:01:00.0: GPU fault detected: 146 0x00339004 [ 2915.586365] radeon 0000:01:00.0: VM_CONTEXT1_PROTECTION_FAULT_ADDR 0x00004B07 [ 2915.586367] radeon 0000:01:00.0: VM_CONTEXT1_PROTECTION_FAULT_STATUS 0x13090004 [ 2915.586370] VM fault (0x04, vmid 9) at page 19207, write from CB (144) [ 2915.586374] radeon 0000:01:00.0: GPU fault detected: 146 0x00539004 [ 2915.586377] radeon 0000:01:00.0: VM_CONTEXT1_PROTECTION_FAULT_ADDR 0x00004B02 [ 2915.586379] radeon 0000:01:00.0: VM_CONTEXT1_PROTECTION_FAULT_STATUS 0x13090004 [ 2915.586382] VM fault (0x04, vmid 9) at page 19202, write from CB (144) [ 2915.586386] radeon 0000:01:00.0: GPU fault detected: 146 0x00739004 . . .
I don't know if i would get them with the changed kernel as-well, but with my stable kernel (3.16) i never see such messages.

Yeah, it's really weird. Looking at the change, the only way I could imagine it possibly having any negative impact would be if it somehow caused the indirect register access method to be used even when it's not necessary. But not sure how that could happen.

That's fine, but we also need to see the VRAM and GTT graphs.

Sorry, completely forget about that.. Another picture with VRAM and GTT usage. I've used `GALLIUM_HUD=fps,requested-VRAM+VRAM-usage,requested-GTT+GTT` to start the benchmark.

Should be ...requested-GTT+GTT-usage
I used to have similar issues with valley, but for my setup/card (R9270X) they are fixed with current mesa + drm-next-3.19-wip.
One thing I always do is set CPUs to performance in case cpufreq messes things up - may be worth a try to see if it helps.
What setting(s)/res do you run valley with?
It may be less hassle for you to use a phone, but FWIW the way I get screenshots that include the HUD is to use xwd - for something fullscreen I would before starting valley from a different xterm/console/whatever do something like -
sleep 100 && xwd -root -out whatever.xwd
then start valley and wait. To view "whatever.xwd" you can use xwud,to upload you could convert to another "normal" format. You need some image program to do this - I have ImageMagick installed and can just type in a terminal -
convert whatever.xwd whatever.png

It's fixed! (for me) - mesa git did the miracle :)
FYI - changing CPU's to performance didn't had any influence. I've made another screenshot, this time with xwd (thanks for the tip btw) and with GTT-usage (thangs for pointing that out - that was a copy paste error). Don't know if it's still important but i'll upload it anyway.
Settings for vally are as followed: Quality: Ultra Stereo 3d: Disabled Monitors: Single Anti-aliasing: Off Full Screen: Yes Resolution: 2560x1600
https://bugzilla.kernel.org/show_bug.cgi?id=86891
--- Comment #21 from Michael Mair-Keimberger bu9zilla@gmail.com --- Just to clarify - the screenshot was made with mesa-10.3.2 and cpu's frequency set to performance.
With mesa git i got following results: FPS: 20.0 Score: 838 Min FPS: 7.4 Max FPS: 30.5
Pretty neat actually! I'll gonna make another benchmark with my patched kernel (git revert 59bc1d8) and look if it has an influence in performance :)
