Bisect landed here. (cc linux-pci at vger.kernel.org)
Hopefully it is helpful, even though I don't see MSI in lspci output
(which is provided below).

    PCI/MSI: Add startup/shutdown for per device domains

    As the RISC-V PLIC cannot apply affinity settings without invoking
    irq_enable(), it will make the interrupt unavailble when used as an
    underlying interrupt chip for the MSI controller.

    Implement the irq_startup() and irq_shutdown() callbacks for the
PCI MSI
    and MSI-X templates.

    For chips that specify MSI_FLAG_PCI_MSI_STARTUP_PARENT, the parent
startup
    and shutdown functions are invoked. That allows the interrupt on
the parent
    chip to be enabled if the interrupt has not been enabled during
    allocation. This is necessary for MSI controllers which use PLIC as
    underlying parent interrupt chip.
