Linux's native # PCIe port service drivers operate independently of both and this can cause # problems. # # The main issue is that the portbus driver will conflict with the platform # specific hotplug driver (pnv_php) over ownership of the MSI used to notify # the host when a hotplug event occurs. The portbus driver claims this MSI on # behalf of the individual port services because the same interrupt is used # for hotplug events, PMEs (on root ports), and link bandwidth change # notifications. The portbus driver will always claim the interrupt even if # the individual port service drivers, such as pciehp, are compiled out. # # The second, bigger, problem is that the hotplug port service driver # fundamentally does not work on PowerNV. The platform assumes that all # PCI devices have a corresponding arch-specific handle derived from the DT # node for the device (pci_dn) and without one the platform will not allow # a PCI device to be enabled. This problem is largely due to historical # baggage, but it can't be resolved without significant re-factoring of the # platform PCI support. # # We can fix these problems in the interim 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. # # This does have the side effect of disabling all port services drivers # that is: AER, PME, BW notifications, hotplug, and DPC. However, this is # not a huge disadvantage on PowerNV since these services are either unused # or handled through other means. # # 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/20191118065553.30362-1-oohall@gmail.com # < /opt/cross/kisskb/korg/gcc-8.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-8.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux-ld --version # < git log --format=%s --max-count=1 be8d3292869350190dac9cd58c75bc005e3fd5c2 # < make -s -j 120 ARCH=powerpc O=/kisskb/build/powerpc-next-rand_powerpc-randconfig_powerpc-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux- randconfig KCONFIG_SEED=0x1B1E4437 # Added to kconfig CONFIG_STANDALONE=y # Added to kconfig CONFIG_BUILD_DOCSRC=n # Added to kconfig CONFIG_MODULE_SIG=n # Added to kconfig CONFIG_CPU_BIG_ENDIAN=y # Added to kconfig CONFIG_PPC64=y # Added to kconfig CONFIG_PPC_DISABLE_WERROR=y # Added to kconfig CONFIG_SECTION_MISMATCH_WARN_ONLY=y # Added to kconfig CONFIG_PREVENT_FIRMWARE_BUILD=y # Added to kconfig CONFIG_CC_STACKPROTECTOR_STRONG=n # Added to kconfig CONFIG_GCC_PLUGINS=n # Added to kconfig CONFIG_LD_HEAD_STUB_CATCH=y # Added to kconfig CONFIG_TRIM_UNUSED_KSYMS=n # Added to kconfig CONFIG_UBSAN=n # yes \n \| make -s -j 120 ARCH=powerpc O=/kisskb/build/powerpc-next-rand_powerpc-randconfig_powerpc-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux- oldconfig yes: standard output: Broken pipe # make -s -j 120 ARCH=powerpc O=/kisskb/build/powerpc-next-rand_powerpc-randconfig_powerpc-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux- /kisskb/src/arch/powerpc/kernel/eeh.c:1769:12: warning: 'proc_eeh_show' defined but not used [-Wunused-function] static int proc_eeh_show(struct seq_file m, void v) ^~~~~~~~~~~~~ /kisskb/src/drivers/power/reset/nvmem-reboot-mode.c: In function 'nvmem_reboot_mode_write': /kisskb/src/drivers/power/reset/nvmem-reboot-mode.c:27:42: error: passing argument 2 of 'nvmem_cell_write' from incompatible pointer type [-Werror=incompatible-pointer-types] ret = nvmem_cell_write(nvmem_rbm->cell, &magic, sizeof(magic)); ^~~~~~ In file included from /kisskb/src/drivers/power/reset/nvmem-reboot-mode.c:10: /kisskb/src/include/linux/nvmem-consumer.h:121:21: note: expected 'const char ' but argument is of type 'unsigned int ' const char buf, size_t len) ~~~~~~~~~~~~^~~ cc1: some warnings being treated as errors make[4]: [/kisskb/src/scripts/Makefile.build:265: drivers/power/reset/nvmem-reboot-mode.o] Error 1 make[3]: * [/kisskb/src/scripts/Makefile.build:509: drivers/power/reset] Error 2 make[2]: * [/kisskb/src/scripts/Makefile.build:509: drivers/power] Error 2 make[2]: * Waiting for unfinished jobs.... make[1]: * [/kisskb/src/Makefile:1650: drivers] Error 2 make[1]: * Waiting for unfinished jobs.... make: *** [Makefile:179: sub-make] Error 2 Command 'make -s -j 120 ARCH=powerpc O=/kisskb/build/powerpc-next-rand_powerpc-randconfig_powerpc-gcc8 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-8.1.0-nolibc/powerpc64-linux/bin/powerpc64-linux- ' returned non-zero exit status 2 # rm -rf /kisskb/build/powerpc-next-rand_powerpc-randconfig_powerpc-gcc8 # Build took: 0:02:01.064526
