While we setup MSI or MSI-X for specific PCI device, the address of MSI or MSI-X capability structure is figured out from the config space for multiple times.

With the patchset applied, the latency for MSI or MSI-X setup would be decreased hopefully. drivers/pci/msi.c | 51 ++++++++++++++++++++------------------ drivers/pci/pcie/portdrv_core.c | 2 +- include/linux/pci.h | 4 +- 3 files changed, 30 insertions(+), 27 deletions(-) Thanks, Gavin -- To unsubscribe from this list: send the line "unsubscribe linux-pci" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
