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-aarch64-glibc-2016.08-613-ge98b4dd/bin/aarch64-linux-gcc --version # < /opt/cross/kisskb/br-aarch64-glibc-2016.08-613-ge98b4dd/bin/aarch64-linux-ld --version # < git log --format=%s --max-count=1 8e80a73fa9a7747e3e8255cb149c543aabf65a24 # < make -s -j 48 ARCH=arm64 O=/kisskb/build/powerpc-fixes_arm64-defconfig_arm64-gcc5.4 CROSS_COMPILE=/opt/cross/kisskb/br-aarch64-glibc-2016.08-613-ge98b4dd/bin/aarch64-linux- defconfig # < make -s -j 48 ARCH=arm64 O=/kisskb/build/powerpc-fixes_arm64-defconfig_arm64-gcc5.4 CROSS_COMPILE=/opt/cross/kisskb/br-aarch64-glibc-2016.08-613-ge98b4dd/bin/aarch64-linux- help # make -s -j 48 ARCH=arm64 O=/kisskb/build/powerpc-fixes_arm64-defconfig_arm64-gcc5.4 CROSS_COMPILE=/opt/cross/kisskb/br-aarch64-glibc-2016.08-613-ge98b4dd/bin/aarch64-linux- olddefconfig # make -s -j 48 ARCH=arm64 O=/kisskb/build/powerpc-fixes_arm64-defconfig_arm64-gcc5.4 CROSS_COMPILE=/opt/cross/kisskb/br-aarch64-glibc-2016.08-613-ge98b4dd/bin/aarch64-linux- warning: ld does not support --fix-cortex-a53-843419; kernel may be susceptible to erratum warning: LSE atomics not supported by binutils Completed OK # rm -rf /kisskb/build/powerpc-fixes_arm64-defconfig_arm64-gcc5.4 # Build took: 0:05:57.697834
