            Bug ID: 93649
           Summary: [radeonsi] Graphics lockup while playing tf2
           Product: Mesa
           Version: 11.0
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: Drivers/Gallium/radeonsi
          Assignee: dri-devel@lists.freedesktop.org
          Reporter: matthew@mjdsystems.ca
        QA Contact: dri-devel@lists.freedesktop.org

Kernel dmesg around the time of the lockup.

After a period of time playing the latest version of TF2, my GPU locks up. 
After the kernel tries to reset, the X becomes stuck and won't work.  The rest
of the system is fine however.  Sometimes, the GPU will reset successfully and
continue working, only to lockup later, eventually freezing X.

Hardware:
GPU: Gigabyte Radeon HD 7970 Ghz edition OC
CPU: AMD Phenom ii X6 1100T
MB: Asus Crosshair IV Formula

Software:
Mesa: 11.1.0
DRM: 2.4.65
LLVM: 3.7.0
X: 1.17.4
DDX: 7.6.1
Kernel: 4.3.3

I have a dmesg with debug turned on and a strace of X from around the time it
crashes (attached).  I reduced the log file to the relevant bits, as they are
quite large.  I'll retry with latest git, see if it helps anywhere.

Radeon blocked locks

Since X seemed blocked on an ioctl, I managed to get a list of all the blocked
locks, and found most of my taken locks were from GUI related programs who
would be doing GL things, and they are all blocked on a lock, including one
that is currently trying to reset my GPU.

I'm guessing there is a lock that is being grabbed twice, once when userspace
makes an ioctl, and again during the reset.  I'll keep digging.


Also, I think this may be a duplicate of #90217, as both involve source games. 
I'll leave this open for now, in case tf2 has a different trigger.

This helps avoid a complete crash when a lockup occurs.

Note this doesn't solve this bug, it just helps manage it.

Can confirm, I have either the same or a similar problem on my R9 390 (using
radeon, with DPM disabled). It doesn't just crash X though, it completely locks
up and I have to reboot to even use TTY. Happens after 10-20 mins of TF2.

Running Arch Linux with everything up to date but no AUR packages, will post
specifics later.

Second patch to fix system lockup after gpu reset

This is already taken accepted from the mailing list, including here for
completeness.

If anyone is experiencing this issue, can you please try with all of these
patches applied?  For now, X should die and restart without acceleration, but
getting a dmesg out or restarting should be fine.

I was asked to file this bug separately.  Also that covers R600, a different
GPU the GCN.

--- Comment #10 from Rosco P. Coltrane <roscofdporg@manashort.com> ---
Same problem here on a fedora 23

GPU: HD 7970
CPU: Intel Core i7 950

Mesa 11.1.0
DRM 2.43.0
LLVM 3.7.0
kernel: 4.3.4

The logs are filed with "ring stalled" and GPU lock messages. I can send more
logs if needed.

radeon 0000:02:00.0: ring 3 stalled for more than 10249msec
radeon 0000:02:00.0: GPU lockup (current fence id 0x000000000001e5f1 last fence
id 0x000000000001e5f2 on ring 3)

I've tried a different firmware
(http://people.freedesktop.org/~agd5f/radeon_ucode/k/) which seemed to have
helped other people with their own problem but it didn't help in my case.

Does it makes sense to try to rollback to an older kernel?

New avoid lockup patch

Latest version as posted to dri-devel.  With these two patches, your system
should no longer lockup forever.  It will freeze the game for a moment, and X
may die for other reasons.

Now the underlying tf2 issue needs investigation.

Any chance VALVe introduced this? They won't admit it.
https://github.com/ValveSoftware/steam-for-linux/issues/4409

The patches attatched here are present in Linux 4.6. I tested linux-git-4.7-rc7
with mesa-git-12.1 compiled against llvm-snv-3.9, and TF2 still crashes.

Setting every graphical option to Low doesn't help.

This is certainly a bug in our driver (unlike what was written on the Github
tracker, a game *can* cause a hang e.g. by writing an infinite loop in a
shader, but that seems exceedingly unlikely in the case of TF2). The problem
with this particular bug is that it seems non-deterministic (i.e. not reliably
reproducible), and that makes it hard to debug.

So there's a chance it won't be fixed at all?

I was thinking about bisecting from version 3.16 (where I know it worked for
me, on Debian Jessie) until ~4.1, but I don't have that kind of time right now.

Actually, if you could find a clear bisection result, that would be
tremendously helpful and would probably lead to a fix.

However, with this kind of bug you need to be extremely sure about what you're
doing when bisecting. For example, if you know that the hang typically occurs
after 10 minutes, then you should play for at least one hour (perhaps even
longer) with each kernel. Otherwise, you might have just gotten lucky, and the
bisect result would be worse than useless.

Yes, I would definitely test it for a long period, something like 16 hours
hehehe.

However, I can't do any besecting right now, I'm tremendously busy at the
moment. Too bad there's not many Linux players with this problem, otherwise
someone would have figured this out already.

Cheers.

I can confirm lastest git head (50b49d242d702e4728329cc59f87d929963e7c53) still
causes lockups, though they seem to come much faster.

Also seems to have a regression regarding lighting, I'll see about bisecting
that in a separate report.

sad to say it did not fix the issue for me. it ran longer than usual though
prior to the crash. I suspect you nixed one issue but multiple are going on.

I'm happy to run any debugging/patches you wish to try.

Marek, since you work for AMD, I wonder if you could get a few hints for the
fix on Catalyst's sources?

It's not so simple. This is a bug somewhere in the Mesa driver such that
looking at other drivers won't likely help.

This is a very weird issue. I think it may not be in Mesa, and here's why:

* On Debian Jessie with kernel 3.16 and Mesa 10.3, the problem doesn't happen;
* On the same Debian, but with mesa backported, the problem also doesn't
happen;
* On the same Debian with Mesa backported and the Kernel backported, the
problem still doesn't happen;
* On Arch Linux with Mesa downgraded to 10.3, the problem happens;
* On the same Arch Linux with Mesa and Kernel downgraded (Kernel to version
3.16 and even 3.10), the problem still happens;
* I'm not 100% sure I downgraded the Firmware on Arch, but I'll try today since
I'm testing a few drivers in Linux;
* On vanilla Arch with Catalyst/FGLRX, the problem doesn't happen;

So I do think this issue is much bigger than everybody thinks and only happens
with a certain combination of Mesa, Kernel, Firmware, and possibly libdrm,
llvm, and other pieces of software as well.

What I really think is that VALVe should investigate this since this problem
started happening after they introduced mandatory Texture Streaming.

Is the elephant in the room in this case the LLVM version difference between
the two setups?

I just tested the oldest firmware available in the Arch Linux Archive, namely
linux-firmware 20130725-1, and the crashes don't happen. This is with current
Arch, not a single package is old and all packages are up-to-date according to
the repos.

I'm hitting 10 to 30 FPS in-game, but at least the crashes don't happen which
IMO is a very good sign of where the problem might be.

I'll report the firmware problem to AMD.

In the mean time, does anyone know how I can try running the firmware from
Catalyst?

@Marek, where is the best place to report this?

According to a Gentoo user who compiled llvm 3.5 and and older version of mesa
against it, the problem still occurs.

So are we certain the hangs are caused by firmware? Bisecting the firmware
would help a lot.

What's your GPU?

--- Comment #32 from Rosco P. Coltrane <roscofdporg@manashort.com> ---
I tested today 3 different firmwares on manjaro (HD7970) 

linux-firmware-20150527.3161bfa-1-any.pkg.tar.xz (chosen because it was a bit
before the first bugs were reported with TF2)

This allowed me to play TF2 without bugs for ~30 min. Then I had the bug
(screen freeze, sound loop) but the system recovered fine after 20 sec with no
loss of performance. I still had a problem before and after the bug with the
mouse pointer which wasn't visible at all time.

linux-firmware-20131013.7d0c7a8-1-any.pkg.tar.xz

This allowed me to play for a good hour, then: bug + recovery after 20 sec. At
the fifth bug the screen simply hanged, TF2 and steam crashed. (had to
ctrl+alt+f2). This one didn't have the mouse bug. This is the most stable TF2
experience I can get.

linux-firmware-20130725-1-any.pkg.tar.xz (earlier firmware available in the
repo)

This one crashed after 2 seconds loading the first map.

The first two firmwares also seem to have fixed the same bug which was present
in "Victor Vran" (same symptoms, screen freeze + sound loop).

not certain but assuming I ran the test correctly, I experienced a crash using
the oldest linux firmware I had linux-firmware-20140828. that leaves 13 months
of time to bisect if linux-firmware 20130725-1 does indeed work. I'll see about
trying installing the 20130725 version later have other stuff I need to do.

commands run to downgrade to linux-firmware-20140828:
sudo pacman -U
/var/cache/pacman/pkg/linux-firmware-20140828.13eb208-1-any.pkg.tar.xz
sudo pacman -S linux

after downgrade I had the following error on boot, so I'm assuming it worked:
Sep 04 09:53:14 jambli kernel: radeon 0000:01:00.0: Direct firmware load for
radeon/TAHITI_vce.bin failed with error -2

game froze again after ~20minutes. using the 20130725 version firmware. so if
downgrading to 20130725 fixes TF2 it likely isn't the same issue as TF2.

If you're testing Mesa git, would you please set GALLIUM_DDEBUG="pipelined
2000" and run TF2, wait until the GPU hangs and repeat. After it happens for
the 3rd time, please zip and attach the contents of ~/ddebug_dumps/*. There
should be 3 files.

Though I've got a hunch that we're just running around in circles.

stellaris run via steam: GALLIUM_DDEBUG="pipelined 2000" %command%

here are the dumps generated.

it seems like a hit or miss if anything was actually written into the files.
the computer completely locks up when it encounter the freeze in stellaris.

stellaris was even more unstable with the GALLIUM_DDEBUG, often failing to even
start up.

Does anyone have a little bit of free time to extract the files from
"lib32-catalyst-libgl" into a system running "lib32-mesa-libgl" and see if that
helps?

I'm also having this problem with Radeon R7 250 (radeonsi), Mesa 12.0.2, LLVM
3.8.1 and kernel version 4.6.0.

If disabling DPM fixed the issue, shouldn't developers study it's code a little
bit? I'm 99.99% positive the issue is in there somewhere, even for AMDGPU
(since RadeonSI and AMDGPU drivers share a lot of code).

Another user previously stated in the thread that they were experiencing the
issues and had DPM disabled.

@Marek Olšák
Please let me know if there's anything I can do to help hunt this bug down.

But that's one user's word against at least 5. Do we even know if the user
actually disabled DPM or has the capacity to do so? Because I'm sure me and
others (like Gentoo users) did in fact disable DPM and the hang didn't happen.
So I don't think our word is less valid just because *one* user claimed he/she
disabled DPM and the hang still happened.

Just tried Mesa-Git (13.1) with the AMDGPU driver on R9 270X. The crash happens
here as well.

However, looking at journalctl I can see new errors from the AMDGPU driver, and
a brief research tells me it could be some TF2 texturing problem.

The error: GPU fault detected: 147 0x000ac802

Similar bugs have been resolved already:

LLVM seems to be related too.

I don't know if it can be of any help, but I've been playing "7 days to die"
during the last weeks, regularly for the last days, and I didn't encounter any
kind of bug.

Until yesterday evening where at my great surprise I had the same bug (freeze,
sound loop) which totally crashed my machine once and only froze it (with a
recovery after a few seconds) twice.

I checked that no update occurred on the game files, on the steam runtime and
on my OS between the days when it worked flawlessly and yesterday when it
crashed 3 time in 15 minutes.

So if it's not only related to files, could it be related to the hardware?
Could it be a faulty card (HD7970), or maybe a mix between a faulty hardware
and some software instruction?

Faulty hardware doesn't make any sense, because:

- It only happens on Linux;

It's probably not the exact same crash, but FWIW I also get crashes with the
proprietary driver and TF2 when I tested it last. I just don't want people to
get their hopes up only to have them let down.

In all honesty, this is one of the most interesting bugs I know. Within all the
people that have it, there are variations to which causes it in the first
place.

What works for me (Debian Jessie with Mesa/libc6 from Backports, for example)
might still cause the crash for some people.

What I do know is that it's not caused by faulty hardware. It could be for
some, but seriously doubt it it's the cause for 99.99% of people experiencing
the issue.

Does this fix the hangs?
https://cgit.freedesktop.org/mesa/mesa/commit/?id=d4d9ec55c589156df4edc227a86b4a8c41048d58

It changes the HTILE (HyperZ) allocation function to
r600_aligned_buffer_create. Without that, the hardware can hang on big GPUs
(Tahiti/Pitcairn/Hawaii/Tonga/etc), but not APUs or small GPUs. The hang
happens when TTM decides to move HTILE to a different location with an
unaligned physical address (which is pretty random). The hardware tries to
access the unaligned address and boom.

Actually, I think that commit only affects Hawaii and Fiji. Other GPUs might be
unaffected, which means the Tahiti hangs are due to a different bug.

I've previously tried disabling hyperz on Tahiti with no luck in side stepping
this bug, so I don't think this is the issue.

Could there be other buffers that need similar treatment that are being
ignored?  Is there an easy way to test this locally?

Unless the changed code works independently of the nohyperz option I don't

 It might be possible that game fixes something, as i see there was game update
3 days ago with the following mentioned in changelog:

 "Improved several aspects of texture handling for OS X and Linux clients

    This should reduce the rate of "Out of memory" errors for players on high
texture settings, especially on level change
    Players still encountering this error can reduce texture quality to medium
or lower to greatly improve stability pending further improvements"

 http://store.steampowered.com/news/25022/

 Just wild guessing that this might change something, since game started to be
unstable on radeonsi when streaming textures and reduction of mem was
introduced last year.

I remember disabling stream textures and still having the issue, as well as

As smoki mentioned, many of the troubles started after Valve's texture
streaming changes to TF2. They'd certainly know what changed in their code, but
for someone like me they're impossible to get a hold of.

Created attachment 127704

package update history that lead to a change in behaviour

Last night the freezes I've been having changed their behaviour. They use to
just cause the system to completely freeze up. Now my system does a immediate
shutdown.

this is interesting because I had just updated linux and mesa-git so I
potentially have a commit range in mesa/llvm which has code related to the
problem. I'm going to rollback my kernel/headers tonight and reboot to rule
that out. And if that doesn't cause the hang to re-appear I'll roll back mesa
tomorrow. and then I'll rollback llvm.

In the meantime I've attached the package update history for the last few days
in case that helps any of the developers.

Are we absolutely sure that it is not a hardware problem?

I haven't seen anything to rule out it being a hardware problem, but Valve's
overwhelming silence on the matter isn't exactly helpful.

I finally found the root cause for my problems.

Turns out my CPU was overheating. But I only stressed it enough when playing
games and nothing showed up in the logs about a shutdown due to heat. Once i
resolved the overheating all my games ran smoothly with no crashes. apologies
for the noise.

Wish I had found it sooner.

I am also see my system completely crash after running Team Fortress 2 for
typically 5-20 minutes.  In the last three occurrences, I've seen the
following:

1. Freeze and system reboot within 10 seconds.  I did not see anything in the
logs.
2. Successful playing for ~30 minutes without issue.
3. Freeze and sound loop.  The screen resets and sound loop changes every 10-20
seconds, which I believe is when the system is trying to reset the GPU. 
However, it never succeeds, and the system becomes completely non-responsive. 
The keyboard does not seem to accept input (num lock is frozen, can't switch to
console).  The only thing I can do is a hard restart.  This scenario happens
almost every time.

Output from journalctl looks like this:
Nov 24 21:26:42 fedora kernel: radeon 0000:01:00.0: ring 3 stalled for more
than 10181msec

If you are right about texture streaming, the cso commit might fix it.

FWIW, the fundamental problem caught by Marek (good catch!) was there for
almost 9 years. It just might not have had quite as severe consequences with
other drivers.

I believe you need mesa-git and llvm-svn for it to work.

Make sure you're using a patched version of the 32 bit libraries too. I managed
to play almost 3 hours in a row in a full server and in different maps without
issues at all.

These are the packages that I'm using:

* linux 4.8.12-2
* linux-firmware 20161005.9c71af9-1

* mesa-git 13.1.0_devel.87233.bd56de8-1
* lib32-mesa-git 13.1.0_devel.87233.bd56de8-1

* llvm-svn 4.0.0svn_r289147-1

Uh oh. This bug may be back.

I'm back on Linux. First time playing for more than 30 mins (my little sister
was playing) PC hangs.

Will test it to see whether it's this hellish bug or not.

Not likely to be the same issue if there is a hang.  Please file a new bug
report.
