The PCIe-native service # drivers bypass both and this can cause problems. # # Historically this hasn't been a big deal since the only port service # driver that saw much use was the AER driver. The AER driver relies on # a kernel service to report when errors occur rather than acting # autonomously so it's fairly easy to ignore. On PowerNV (and pseries) # AER events are handled through EEH, which ignores the AER service, so # it's never been an issue. # # Unfortunately, the hotplug port service driver (pciehp) does act # autonomously and conflicts with the platform specific hotplug # driver (pnv_php). The main issue is that pciehp claims the interrupt # associated with the PCIe capability which in turn prevents pnv_php # from claiming it. # # This results in hotplug events being handled by pciehp which does not # notify firmware when the PCIe topology changes, and does not # setup/teardown the arch specific PCI device structures (pci_dn) when # the topology changes. The end result is that hot-added devices cannot # be enabled and hot-removed devices may not be fully torn-down on # removal. # # We can fix these problems by setting the "pcie_ports_disabled" flag # during platform initialisation. The flag indicates the platform owns # the PCIe ports which stops the portbus driver from being registered. # # Fixes: 66725152fb9f ("PCI/hotplug: PowerPC PowerNV PCI hotplug driver") # Signed-off-by: Oliver O'Halloran <oohall@gmail.com> # Signed-off-by: Michael Ellerman <mpe@ellerman.id.au> # Link: https://lore.kernel.org/r/20191113094035.22394-1-oohall@gmail.com # < /opt/cross/kisskb/korg/gcc-8.1.0-nolibc/x86_64-linux/bin/x86_64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-8.1.0-nolibc/x86_64-linux/bin/x86_64-linux-ld --version # < git log --format=%s --max-count=1 942523fd67563ea677cc03fc97635893d4350749 # < make -s -j 80 ARCH=x86 O=/kisskb/build/powerpc-next_x86-allmodconfig_x86_64-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/x86_64-linux/bin/x86_64-linux- allmodconfig # Added to kconfig CONFIG_BUILD_DOCSRC=n # Added to kconfig CONFIG_MODULE_SIG=n # Added to kconfig CONFIG_SAMPLES=n # yes \n | make -s -j 80 ARCH=x86 O=/kisskb/build/powerpc-next_x86-allmodconfig_x86_64-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/x86_64-linux/bin/x86_64-linux- oldconfig yes: standard output: Broken pipe # make -s -j 80 ARCH=x86 O=/kisskb/build/powerpc-next_x86-allmodconfig_x86_64-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/x86_64-linux/bin/x86_64-linux- /kisskb/src/tools/objtool /kisskb/src/security/integrity/platform_certs/load_uefi.c:17:19: warning: 'efi_cert_sha256_guid' defined but not used [-Wunused-variable] static efi_guid_t efi_cert_sha256_guid __initdata = EFI_CERT_SHA256_GUID; ^~~~~~~~~~~~~~~~~~~~ /kisskb/src/security/integrity/platform_certs/load_uefi.c:15:19: warning: 'efi_cert_x509_sha256_guid' defined but not used [-Wunused-variable] static efi_guid_t efi_cert_x509_sha256_guid __initdata = ^~~~~~~~~~~~~~~~~~~~~~~~~ /kisskb/src/security/integrity/platform_certs/load_uefi.c:14:19: warning: 'efi_cert_x509_guid' defined but not used [-Wunused-variable] static efi_guid_t efi_cert_x509_guid __initdata = EFI_CERT_X509_GUID; ^~~~~~~~~~~~~~~~~~ Completed OK # rm -rf /kisskb/build/powerpc-next_x86-allmodconfig_x86_64-gcc8 # Build took: 0:23:49.218719
