Recently Jeffrey Hugo made 4 patches to the vPCI driver so multiple-MSI can work now. Please consider picking up the 4 patches into the linux-azure kernels for Ubuntu LTS 18.04, 20.04 and 22.04: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=08e61e861a0e47e5e1a3fb78406afd6b0cea6b6d https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=455880dfe292a2bdd3b4ad6a107299fce610e64b https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=b4b77778ecc5bfbd4e77de1b2fd5c1dd3c655f1f https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=a2bad844a67b1c7740bda63e87453baf63c3a7f7 Microsoft is working to bring up a Qualcomm PCIe device to Linux VMs running on Azure. We need the 4 patches for the device to work on Azure/Hyper-V. The 5.4 kernel patches are a mix of cherry picks and backports since cherry picking scaffold patches would have been too intrusive, whereas for the 5.15 kernel I chose some scaffolding patches in order to have all clean cherry picks. [Test Plan] Microsoft tested both 5.4 and 5.15 kernels. [Where things could go wrong] MSI vectors could be mis-wired or ignored.
