Subject: [PATCH v2 0/2] PCI/ERR: s390/pci: Use pci_uevent_ers() in PCI recovery
Date: Mon, 23 Jun 2025 10:41:31 +0200	[thread overview]
Message-ID: <20250623-add_err_uevents-v2-0-a3a2cf8e711d@linux.ibm.com> (raw)

Hi All,

This series adds issuing of uevents during PCI recovery on s390. In
developing this I noticed that pci_uevent_ers() ignores
PCI_ERS_RESULT_NEED_RESET which  results in
AER not generating a uevent at the beginning of recovery if drivers
request a reset as it uses the result of error_detected() as parameter
to pci_uevent_ers(). This is fixed in the first patch and relied upon by
the s390 recovery code as it also uses the result of error_detected().

Thanks,
Niklas

Changes in v2:
- Add a patch fixing pci_uevent_ers() mistakenly ignoring PCI_ERS_RESULT_NEED_RESET
- Use the result of error_detected() for initial pci_uevent_ers()
- Drop fixes tag in s390 patch
- Rebase and re-test on current master
- Link to v1: https://lore.kernel.org/r/20250424-add_err_uevents-v1-1-3384d6b779c6@linux.ibm.com
