This is a note to let you know that I've just added the patch titled
PCI: hv: Fix multi-MSI to allow more than one MSI vector
(+ stable@vger.kernel.org)
Hi Sasha and stable kernel maintainers, If we want to support multi-MSI in the pci-hyperv driver, we need all of the 4 patches:
08e61e861a0e ("PCI: hv: Fix multi-MSI to allow more than one MSI vector") 455880dfe292 ("PCI: hv: Fix hv_arch_irq_unmask() for multi-MSI") b4b77778ecc5 ("PCI: hv: Reuse existing IRTE allocation in compose_msi_msg()") a2bad844a67b ("PCI: hv: Fix interrupt mapping for multi-MSI")
Multi-MSI can't work properly if we only pick up the first patch.
We need to either pick up all the 4 patches to 5.18/5.17/etc. or pick up nothing. I suggest we pick up all the 4 patches. The patch author Jeffrey may want to chime in.
Thanks, -- Dexuan
