Subject: [PATCH v2] PCI/MSI: Re-add checks for skip masking MSI-X on Xen PV
Date: Tue, 19 Oct 2021 23:48:19 +0200 [thread overview]
Message-ID: <5f050b30-fa1c-8387-0d6b-a667851b34b0@oderland.se> (raw)

PCI/MSI: Re-add checks for skip masking MSI-X on Xen PV
commit fcacdfbef5a1 ("PCI/MSI: Provide a new set of mask and unmask
functions") introduce functions pci_msi_update_mask() and
pci_msix_write_vector_ctrl() that is missing checks for
pci_msi_ignore_mask that exists in commit 446a98b19fd6 ("PCI/MSI: Use
new mask/unmask functions"). Add them back since it is
causing severe lockups in amdgpu drivers under Xen during boot.
As explained in commit 1a519dc7a73c ("PCI/MSI: Skip masking MSI-X
on Xen PV"), when running as Xen PV guest, masking MSI-X is a
responsibility of the hypervisor.
Fixes: fcacdfbef5a1 ("PCI/MSI: Provide a new set of mask and unmask
functions")

v1
* commit log is not in the correct mood
* commit log has single quotes around the commits
* the information with what led up to the patch is lacking.
v2
* correct the mood
* correct the quotes
* add much more information.
Here I describe the current patch and what led up to it,
more on what led up to it below the first attached dmesg.
This patch solves a major issue with booting 5.15-rc1 under Xen
with amdgpu drivers. Specifically Lenovo P14s Gen 1, AMD 4750U.
During boot around when I unluck the disk the first entry of
'Fence fallback timer expired' occur, the laptop is mostly useless.
After a while the WARN_ON trace shows up and the boot process starts
again, until it again gets stuck. This pattern repeats until X boots,
after that point it's kind of ok to work in.
If I try to switch to console the same process happens.
My solution to this was at first bisecting and finding
commit 446a98b19fd6 ("PCI/MSI: Use new mask/unmask functions") series,
reverting this commit made the boot fast again with no lockups.
Later on I tried to apply pci=nomsi as a kernel argument and that
worked fine as well, letting me compile the kernel without the revert.
I have to note that this is my first commit and PCI/MSI area is
not my area of expertise. I tried to mimic what was
obviously missing between the aforementioned commits. There may be
better ways to solve this problem, or other places to put the checks.
Should desc->msi_attrib.is_virtual be checked? It is not checked in
'commit 1a519dc7a73c ("PCI/MSI: Skip masking MSI-X on Xen PV")'
If there's anything I can try out, I'd be happy to assist.
The important bits from dmesg, with debug-configs on.

Full log with drm.debug=1 can be be found at the original issue
https://gitlab.freedesktop.org/drm/amd/-/issues/1715
https://gitlab.freedesktop.org/drm/amd/uploads/c91af638cb8fb5f3c25130f1edabb47e/dmesg
My original goal was to solve suspend/resume, that is why I'm testing
out v5.15. During that investigation I have found that:
* v5.15-rc2+ with pci=nomsi is quite resilient to crashing amdgpu drivers
* Compiling with CONFIG_HSA_AMD=n makes a difference, I don't believe Xen
has proper support for HSA anyhow.
* Compiling with CONFIG_AMD_PMC=y makes a difference, apparently qiurks
are enabled when not compiling as a module.
I did a last honest try with v5.15-rc5 with this patch applied to get more
data and I did find some more. The original problem show itself, but since
amdgpu actually describes their firmware commands now, it became less cryptic.
After this message the screen will be blank, I can still get passed the xscreensaver
but the screen is dead. With pci=nomsi applied I can after suspending the laptop
once more, get the screen back in order. This also occurs without starting X.
