Due to this, a KVM on # PowerVM guest cannot be booted with the XICS interrupt controller as # doorbells are to be setup in the initial probe path when using XICS # (pSeries_smp_probe()). Add DPDES support in the host KVM code to fix # doorbell emulation. # # Fixes: 6ccbbc33f06a ("KVM: PPC: Add helper library for Guest State Buffers") # Cc: stable@vger.kernel.org # v6.7+ # Signed-off-by: Gautam Menghani # Signed-off-by: Michael Ellerman # Link: https://lore.kernel.org/stable/20240522082838.121769-1-gautam%40linux.ibm.com # < /opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux-ld --version # < git log --format=%s --max-count=1 57584d4249870a4d382f0016981ceae5c9b2eebc # make -s -j 40 ARCH=powerpc O=/kisskb/build/powerpc-fixes_pseries_le_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- pseries_le_defconfig Using /kisskb/src/arch/powerpc/configs/ppc64_defconfig as base Merging /kisskb/src/arch/powerpc/configs/le.config Merging /kisskb/src/arch/powerpc/configs/guest.config Value of CONFIG_VIRTIO_BLK is redefined by fragment /kisskb/src/arch/powerpc/configs/guest.config: Previous value: CONFIG_VIRTIO_BLK=m New value: CONFIG_VIRTIO_BLK=y Value of CONFIG_SCSI_VIRTIO is redefined by fragment /kisskb/src/arch/powerpc/configs/guest.config: Previous value: CONFIG_SCSI_VIRTIO=m New value: CONFIG_SCSI_VIRTIO=y Value of CONFIG_VIRTIO_NET is redefined by fragment /kisskb/src/arch/powerpc/configs/guest.config: Previous value: CONFIG_VIRTIO_NET=m New value: CONFIG_VIRTIO_NET=y Value of CONFIG_VIRTIO_CONSOLE is redefined by fragment /kisskb/src/arch/powerpc/configs/guest.config: Previous value: CONFIG_VIRTIO_CONSOLE=m New value: CONFIG_VIRTIO_CONSOLE=y Value of CONFIG_VIRTIO_PCI is redefined by fragment /kisskb/src/arch/powerpc/configs/guest.config: Previous value: CONFIG_VIRTIO_PCI=m New value: CONFIG_VIRTIO_PCI=y Value of CONFIG_VIRTIO_BALLOON is redefined by fragment /kisskb/src/arch/powerpc/configs/guest.config: Previous value: CONFIG_VIRTIO_BALLOON=m New value: CONFIG_VIRTIO_BALLOON=y Value of CONFIG_VHOST_NET is redefined by fragment /kisskb/src/arch/powerpc/configs/guest.config: Previous value: CONFIG_VHOST_NET=m New value: CONFIG_VHOST_NET=y Value of CONFIG_IBMVETH is redefined by fragment /kisskb/src/arch/powerpc/configs/guest.config: Previous value: CONFIG_IBMVETH=m New value: CONFIG_IBMVETH=y Value of CONFIG_IBMVNIC is redefined by fragment /kisskb/src/arch/powerpc/configs/guest.config: Previous value: CONFIG_IBMVNIC=m New value: CONFIG_IBMVNIC=y Merging /kisskb/src/arch/powerpc/configs/kvm_guest.config # # merged configuration written to .config (needs make) # # < make -s -j 40 ARCH=powerpc O=/kisskb/build/powerpc-fixes_pseries_le_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- help # make -s -j 40 ARCH=powerpc O=/kisskb/build/powerpc-fixes_pseries_le_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- olddefconfig # make -s -j 40 ARCH=powerpc O=/kisskb/build/powerpc-fixes_pseries_le_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- Completed OK # rm -rf /kisskb/build/powerpc-fixes_pseries_le_defconfig_powerpc-gcc5 # Build took: 0:01:57.622686
