Hi Bjorn, Lukas, Mahesh, 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. I think this will result in AER not generating a uevent at the beginning of recovery if drivers request a reset via the voting on error_detected() returns. This is fixed in the first patch and relied upon by the s390 recovery code as it also uses the result of error_detected() though with one device/driver at a time.
Thanks, Niklas Signed-off-by: Niklas Schnelle <schne...@linux.ibm.com> --- Changes in v5: - Add R-b from Lukas Wunner for EEH - Improve commit message for EEH (Lukas Wunner) - Move the EEH patch to the end so the reference to s390 relies on the as is and not future state ;) - Link to v4: https://lore.kernel.org/r/20250807-add_err_uevents-v4-0-c624bfd86...@linux.ibm.com Changes in v4: - Add change in EEH to use the return of error_detected() in the uevent just like AER and the new s390 code - Add R-b from Lukas - Link to v3: https://lore.kernel.org/r/20250730-add_err_uevents-v3-0-540b158c0...@linux.ibm.com Changes in v3: - Reworded cover letter - Rebase on v6.16 - Link to v2: https://lore.kernel.org/r/20250623-add_err_uevents-v2-0-a3a2cf8e7...@linux.ibm.com 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-v1-1-3384d6b77...@linux.ibm.com --- Niklas Schnelle (3): PCI/AER: Fix missing uevent on recovery when a reset is requested PCI/ERR: s390/pci: Use pci_uevent_ers() in PCI recovery powerpc/eeh: Use result of error_detected() in uevent arch/powerpc/kernel/eeh_driver.c | 2 +- arch/s390/pci/pci_event.c | 3 +++ drivers/pci/pci-driver.c | 3 ++- include/linux/pci.h | 2 +- 4 files changed, 7 insertions(+), 3 deletions(-) --- base-commit: 038d61fd642278bab63ee8ef722c50d10ab01e8f change-id: 20250417-add_err_uevents-6f8d4d7ce09c Best regards, -- Niklas Schnelle
