[REGRESSION] amdgpu: async system error exception from hdp_v5_0_flush_hdp()

[Alexey Klimov]

#regzbot introduced: v6.12..v6.13

I use RX6600 on arm64 Orion o6 board and it seems that amdgpu is broken on recent kernels, fails on boot:

---[ end Kernel panic - not syncing: Asynchronous SError Interrupt ]---

(bios version seems to be 45 years old but that is the state of the board
when I received it)

Also saw this crash with RX6700. Old radeons like HD5450 and nvidia gt1030
work fine on that board.

A little bit of testing showed that it was introduced between 6.12 and 6.13.
Also it seems that changes were taken by some distro kernels already and
different iso images I tried failed to boot before I bumped into some iso
with kernel 6.8 that worked just fine.

The only change related to hdp_v5_0_flush_hdp() was
cf424020e040 drm/amdgpu/hdp5.0: do a posting read when flushing HDP

Reverting that commit ^^ did help and resolved that problem. Before sending
revert as-is I was interested to know if there supposed to be a proper fix
for this or maybe someone is interested to debug this or have any suggestions.

In theory I also need to confirm that exactly that change introduced the
regression.

Thanks,
Alexey

Can you revert the change and try again https://gitlab.com/linux-kernel/linux/-/commit/cf424020e040be35df05b682b546b255e74a420f

Please read my email in the first place.

Well in general we already had tons of problems with low end ARM64 boards. So first question of all is that board SBSA certified?

If not then the chances of that board actually working correctly are very low unfortunately.

Any idea what that error code means?

Thanks,
Christian.

We can't really revert the change as that will lead to coherency
problems.  What is the page size on your system?  Does the attached
patch fix it?

Subject: [PATCH] drm/amdgpu: don't remap HDP registers if page size is > 4K

We remap the HDP registers to an open part of the MMIO
aperture if page size is < 4K, but if it's > 4k, we remap
the HDP registers back to themselves.  This doesn't seem
to work properly, at least on ARM systems, so just skip
the HDP remap altogether if page size is > 4K.

Fixes: c9b8dcabb52a ("drm/amdgpu/hdp4.0: do a posting read when flushing HDP")
Fixes: cf424020e040 ("drm/amdgpu/hdp5.0: do a posting read when flushing HDP")
Fixes: f756dbac1ce1 ("drm/amdgpu/hdp5.2: do a posting read when flushing HDP")

OK.  that patch won't change anything then.  Can you try this patch instead?

Alex, it is very sorry that our team don't have the GPU card in hands. 
It is better to ask amd gfx team help to try the fixes.

Sorry, we don't have the problematic arm board.  This code works as

Config I am using is basically defconfig wrt memory parameters, yeah, i use 4k.

So I tested that patch, thank you, and some other different configurations --
nothing helped. Exactly the same behaviour with the same backtrace.

So it seems that it is firmware problem after all?

Yeah, I can imagine.
I can't find any info about SBSA cartification for that board hence I'd say that
state is unknown, hence most likely "no". At least that's what I think.
It is a good question for cix or cixtech.com-based emails.

They have some updated potentially unstable UEFI firmwares to test though.

Well, current thinking process that it means:
-- bits 31:26 system error interrupt;
-- bit 25 indicates that it was 32-bit instruction;
-- 0x11 in lsb is probably implementation-defined which can
be anything like bus errors, parity, access violations, etc

That's probably not very helping here.

Alexey

Did you test the first (4k check) or the second (don't remap on ARM) patch?

>

There is no GPU firmware involved in this operation.  It's just a
posted write.  E.g., we write to a register to flush the HDP write
queue and then read the register back to make sure the write posted.
If the second patch didn't help, then perhaps there is some issue with
MMIO access on your platform?

The second one. I think you mentioned that first one won't help for 4k pages.

I didn't mean GPU firmware at all. I only had uefi/EL3 firmwares in mind.

Completely out of the blue, based on nothing, do you think that
adding delay/some mem barrier between write and read might help?
I wonder if host data path code should be executed during common desktop
usage as a common user then why it doesn't break later. But yeah, I also
think this is this motherboard problem. Thank you.

That would still be quite some platform bug.

Maybe it's some kind of write/read re-ordering issue.

 But yeah, I also think this is this motherboard problem. Thank you.

You should probably ping some ARM guys to figure out what the fault code actually means.

Hi Alexey,

This board has just got Arm SystemReady SR v2.5 certificate, See
attachment. Arm is in the process of updating the list, so you may
can't find it in website now.

I think I found the problem.  The previous patch wasn't doing what I

Subject: [PATCH] drm/amdgpu: only remap HDP registers on X86_64

We remap the HDP registers to an open part of the MMIO
aperture.  This doesn't seem to work properly on non-X86 systems,
so only remap on X86_64.

I think I have a better solution.  Please try these patches instead.  Thanks!

For the RX6600, you only need patch 0003.  The rest of the series
fixes up other chips.

Thanks,

Sorry for the delay.
Finally managed to find some time to test it.
It seems that patches are merged in the current -rc tree so I just
re-tested -rc5.
All works. Thank you.

A bit annoying thing is repeating:
[drm] Unknown EDID CEA parser results
and I also didn't observe such messages before on -rc2 or -rc3:
amdgpu 0000:c3:00.0: amdgpu: [drm] amdgpu: DP AUX transfer fail:4

dmesg is in attachment. But I don't think that these are related to
hdp_v5_0_flush_hdp() issue.

Best regards,
Alexey
