Hi Bjorn. The patch v6 looks good to me. It works ok on HiSilicon hip08 platform. Tested-by: Dongdong Liu <liudongdong3@xxxxxxxxxx> 在 2017/10/21 0:21, Bjorn Helgaas 写道:
This is based on Dongdong's series: v3: http://lkml.kernel.org/r/1507553167-27833-1-git-send-email-liudongdong3@xxxxxxxxxx v4: http://lkml.kernel.org/r/1507719178-112556-1-git-send-email-liudongdong3@xxxxxxxxxx v5: http://lkml.kernel.org/r/20171019225726.17806.62380.stgit@xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx The main idea is to fix IRQ issues when removing and adding back a Root Port. The problem is that when we allocate, free, and reallocate MSI/MSI-X vectors for the device, we may not get the same vectors the second time, but we saved IRQs based on the first set of vectors. Changes in v5: - add back a general Interrupt Message Number comment - factor out Interrupt Message Number helper separately This is on pci/msi for v4.15. --- Bjorn Helgaas (3): PCI/portdrv: Consolidate comments PCI/portdrv: Factor out Interrupt Message Number lookup PCI/portdrv: Compute MSI/MSI-X IRQ vectors after final allocation Dongdong Liu (1): PCI/portdrv: Add #defines for AER and DPC Interrupt Message Number masks drivers/pci/pcie/portdrv_core.c | 171 +++++++++++++++++---------------------- include/uapi/linux/pci_regs.h | 2 2 files changed, 77 insertions(+), 96 deletions(-) .
