With this new # flag, the revmap_tree of the IRQ domain is not used anymore. This # change broke the support of shared LSIs [1] in the XIVE driver because # it was relying on a lookup in the revmap_tree to query previously # mapped interrupts. Linux now creates two distinct IRQ mappings on the # same HW IRQ which can lead to unexpected behavior in the drivers. # # The XIVE IRQ domain is not a direct mapping domain and its HW IRQ # interrupt number space is rather large : 1M/socket on POWER9 and # POWER10, change the XIVE driver to use a 'tree' domain type instead. # # [1] For instance, a linux KVM guest with virtio-rng and virtio-balloon # devices. # # Fixes: 4f86a06e2d6e ("irqdomain: Make normal and nomap irqdomains exclusive") # Cc: stable@vger.kernel.org # v5.14+ # Signed-off-by: Cédric Le Goater <clg@kaod.org> # Tested-by: Greg Kurz <groug@kaod.org> # Acked-by: Marc Zyngier <maz@kernel.org> # Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> # Link: https://lore.kernel.org/r/20211116134022.420412-1-clg@kaod.org # < /opt/cross/kisskb/br-mipsel-o32-full-2016.08-613-ge98b4dd/bin/mipsel-linux-gcc --version # < /opt/cross/kisskb/br-mipsel-o32-full-2016.08-613-ge98b4dd/bin/mipsel-linux-ld --version # < git log --format=%s --max-count=1 8e80a73fa9a7747e3e8255cb149c543aabf65a24 # < make -s -j 48 ARCH=mips O=/kisskb/build/powerpc-fixes_mips-defconfig_mipsel CROSS_COMPILE=/opt/cross/kisskb/br-mipsel-o32-full-2016.08-613-ge98b4dd/bin/mipsel-linux- defconfig # < make -s -j 48 ARCH=mips O=/kisskb/build/powerpc-fixes_mips-defconfig_mipsel CROSS_COMPILE=/opt/cross/kisskb/br-mipsel-o32-full-2016.08-613-ge98b4dd/bin/mipsel-linux- help # make -s -j 48 ARCH=mips O=/kisskb/build/powerpc-fixes_mips-defconfig_mipsel CROSS_COMPILE=/opt/cross/kisskb/br-mipsel-o32-full-2016.08-613-ge98b4dd/bin/mipsel-linux- olddefconfig # make -s -j 48 ARCH=mips O=/kisskb/build/powerpc-fixes_mips-defconfig_mipsel CROSS_COMPILE=/opt/cross/kisskb/br-mipsel-o32-full-2016.08-613-ge98b4dd/bin/mipsel-linux- /kisskb/src/arch/mips/boot/dts/img/boston.dts:128.19-178.5: Warning (pci_device_reg): /pci@14000000/pci2_root@0,0,0: PCI unit address format error, expected "0,0" <stdin>:1559:2: warning: #warning syscall futex_waitv not implemented [-Wcpp] Completed OK # rm -rf /kisskb/build/powerpc-fixes_mips-defconfig_mipsel # Build took: 0:02:01.475933
