dmesg with RX460

Hello,

I have the same messages with one RX460 coming from X and plasmashell on my system. Running 4.15.0 and mesa 18.0.0 on opensuse Tumbleweed. I'm attaching some lines from dmesg.

Regards,
Stratos
Comment 16 Matthew Scheirer 2018-02-09 03:09:05 UTC 
I get this as well with a 290 on 4.15 ONLY when DC is enabled. Its a dirty enough taint to leave btrfs volumes in inconsistent states so its straight crashing the kernel.

The swiotlb messages this report is about are harmless (though a fix is on the way anyway), the other issues you mention are probably not directly related.

I can say that it is not completely harmless. I'm using virtualbox on my KDE plasma desktop and I have several crashes on windows VMs which are "aborted" while running. At the time the "aborted" is happening, I can see a flood of this type of messages on my logs. Didn't had any issue with my windows virtualbox VMs up to now and the "aborted" crash has resulted on broken VMs who need repair. Although haven't seen any btrfs corruption or other issue.

That's either simply coincidence, or means the kernel ran out of memory. The messages this report is about are triggered by transient memory allocation failures, for which there is a fallback path.

Maybe it is a coincidence, for sure I'm not running out of memory when it is happening and started with kernel 4.15 and (or) Mesa 18.0 without any change on Virtualbox side. I'll wait for the fix to see what happens...

Well the message means that we ran out of memory to allocate a 2MB block and instead use many small 4K blocks.

What could be is that there is a memory leak somewhere triggering both the message and the VM faults you are seeing.

I am getting these messsages on my machine right now, too.

There is enough RAM left to allocate a 2 MiB block.

> There is enough RAM left to allocate a 2 MiB block.

No there isn't. 1229536 pages free means that there are 1229536 4k pages available that doesn't tell us anything about 2MB pages, nor if those are usable for swiotlb.

Take a look at /proc/pagetypeinfo. There must at least be pages at order 9 or higher for an 2MB swiotlb allocation to succeed.

An alternative workaround is David Zhou's patch which completely avoids the swiotlb allocator on x86.

OK, I had a look and if I got it right: memory fragmentation lets the malloc fail. <nitpick>I still would not call that to "run out of memory" - there is enough memory available, its current layout is just not in the desired shape.</nitpick> ;)

Yeah, correct.

One interesting point is that this only seems to happen when DC is enabled, so that points to a possible memory leak there.

Would be interesting to monitor amdgpu_gem_info if there are an increasing number of buffers around when DC is enabled.

I do still get the swiotlib OOM errors without DC enabled, but they are fairly infrequent and don't panic crash the kernel. With DC enabled, swiotlib OOM messages happen much more often coinciding with crashes.

Thanks and yeah that only means that DC releases the memory later than the classic code path.

So actually not DC related.

I didn't understand It's already fixed in which commit?
If yes why I see this issue with latest build amd-staging-drm-next?

See here https://lkml.org/lkml/2018/1/16/106. I've already pinged Konrad multiple times as well, but I'm still not sure if and when he send that patch to Linus.

The real point is that those messages are just false positives, e.g. they are completely harmless and we haven't rebased amd-staging-drm-next in a while which is most likely the reason why it isn't in there.

Comment 33 mikhail.v.gavrilov 2018-02-12 03:31:35 UTC 
Why are you sure what this totally harmless?
I have proof this this isn't it.
Look at my system log:
- I got message "amdgpu 0000:07:00.0: swiotlb buffer is full (sz: 2097152 bytes)" at Feb 10 18:46:00
- And then happened that gnome-shell crashed  2 seconds later at "Feb 10 18:48:53"

Today gnome-shell not crashed but I noted that gnome-terminal was closed after this.
Feb 12 02:30:58 localhost.localdomain gnome-terminal-[2799]: Error flushing display: Resource temporarily unavailable

Of course, this may just be a coincidence, but the unpleasant residue remains.

> Why are you sure what this totally harmless?

Those messages are a sympton and not a cause. E.g. take a look at your logs again, gnome-shell started to crash before you got the message.

What happens in your case is that some process or the kernels runs away with memory and because of this you get the message and the crash.

We can disabled the warning message, but fixing the root problem is a complete different task.
Comment 35 Nick Lee 2018-03-03 20:05:05 UTC 
The same on NVIDIA Corporation C79 [GeForce 9300 / nForce 730i] (rev b1).
This happens when high disk IO load. For example - copy foles from HDD to USB.

I see that on `amd-staging-drm-next` branch which branched from 4.16-rc1 this issue not happens now, but on mainline 4.16-rc6 still actively occurred again and again.

[19615.347634] swiotlb_tbl_map_single: 46 callbacks suppressed
Comment 40 Jean Delvare 2018-04-20 13:28:15 UTC 
I believe there are 2 incarnations of this bug, with the same symptoms but different root causes.

The first bug is affecting kernels v4.14 and v4.15, it is caused by 2 MB allocations failing too verbosely when in fact 4 kB allocations worked just fine as a fallback. That one is fixed in v4.16 by:

commit d0bc0c2a31c95002d37c3cc511ffdcab851b3256
Author: Christian König
Date:   Thu Jan 4 14:24:19 2018 +0100

    swiotlb: suppress warning when __GFP_NOWARN is set

However kernel v4.16 also includes the following commit:

commit 0176adb004065d6815a8e67946752df4cd947c5b
Author: Christoph Hellwig
Date:   Tue Jan 9 22:15:30 2018 +0100

    swiotlb: refactor coherent buffer allocation

which contains a bug producing exactly the same backtraces. That bug is caused by an improper check of the result of dma_coherent_ok(), which was fixed 10 days ago with:

commit 9e7f06c8beee304ee21b791653fefcd713f48b9a
Author: Takashi Iwai
Date:   Tue Apr 10 19:05:13 2018 +0200

    swiotlb: fix unexpected swiotlb_alloc_coherent failures

I backported this fix on top of v4.16.3 and the backtraces are gone. The commit was tagged for stable inclusion so I expect it to be included in v4.16.
Comment 41 Jean Delvare 2018-04-21 15:51:35 UTC 
Bah, I spoke too fast. Even with commit 9e7f06c8beee ("swiotlb: fix unexpected swiotlb_alloc_coherent failures") backported, I end up seeing the backtraces again, after several hours. So that commit helps but doesn't solve the problem. It seems there are at least 3 different bugs leading to the same problem.
Comment 42 Stratos Zolotas 2018-04-22 07:24:06 UTC 
I can confirm that I'm getting the backtraces on Opensuse Tumbleweed with 4.16.2 kernel installed. They appear fewer times now but every time I have a flickering on my monitors (using a 3 monitor setup).

Same here on ryzen 2400g + asus a320m-k w/ iommu disabled, vanilla kernel 4.16.4.

I'm not sure if it's another issue since it happens on driver loading and backtrace looks like:

[Wed Apr 25 20:18:50 2018]  dump_stack+0x67/0x93
[Wed Apr 25 20:18:50 2018]  swiotlb_alloc_coherent+0x1da/0x1f0
[Wed Apr 25 20:18:50 2018]  amdgpu_ih_ring_init+0x1fc/0x2c0 [amdgpu]

[Wed Apr 25 20:18:50 2018]  amdgpu_driver_load_kms+0x56/0x170 [amdgpu]

but it happens after `swiotlb buffer is full` error, so writing here.

It is, please file your own report.
Comment 47 Jean Delvare 2018-04-27 10:50:30 UTC 
Problem still present in kernel 4.16.5. I guess I'll have to bisect it...
Comment 48 Barto 2018-04-27 23:11:08 UTC 
the bug occurs also with radeon driver, and not only amdgpu :

radeon 0000:01:00.0: swiotlb buffer is full (sz: 2097152 bytes)
radeon 0000:01:00.0: swiotlb: coherent allocation failed, size=2097152

my graphic card : amd radeon HD4650 Pcie

Comment 49 Barto 2018-04-27 23:17:15 UTC 
full log error, it seems related to ttm code, I use the radeon driver (not amdgpu) :

Comment 50 Michel Dänzer 2018-05-01 13:34:00 UTC 
The remaining issue should be fixed with https://patchwork.freedesktop.org/patch/219765/ .

Anyway, the issues in 4.16 were swiotlb regressions, not directly related to the issue originally reported here. If there's ever an issue again with the fix above and Takashi-san's fix referenced in comment  40, please report it to the swiotlb developers instead of here.
