This adds a new function pnv_opal_pci_msi_eoi() which does the part of end-of-interrupt (EOI) handling of an MSI which involves doing an OPAL call. This function can be called in real mode. This doesn't just export pnv_ioda2_msi_eoi() because that does a call to icp_native_eoi(), which does not work in real mode. This also adds a function, is_pnv_opal_msi(), which KVM can call to check whether an interrupt is one for which we should be calling pnv_opal_pci_msi_eoi() when we need to do an EOI. [paulus@ozlabs.org - split out the addition of pnv_opal_pci_msi_eoi() from Suresh's patch "KVM: PPC: Book3S HV: Handle passthrough interrupts in guest"; added is_pnv_opal_msi(); wrote description.] Signed-off-by: Suresh Warrier <warrier@linux.vnet.ibm.com> Signed-off-by: Paul Mackerras <paulus@ozlabs.org> |
