The bridge-port and devices behind the bridge, which # become offline by hot-unplug operation, don't get hot-plugged/enabled # by doing hot-plug operation on that slot. Only the first port of the # bridge gets enabled and the remaining port/devices remain unplugged. The # hot plug/unplug operation is done by the hotplug driver (drivers/pci/ # hotplug/pnv_php.c). # # This behavior is due to missing code for the switch/bridge. The existing # driver depends on pci_hp_add_devices() function for device enablement. # This function calls pci_scan_slot() on only one device-node/port of the # bridge, not on all the siblings' device-node/port. # # The missing code needs to be added which will find all the sibling # device-nodes/bridge-ports and will run explicit pci_scan_slot() # on those. A new function has been added for this purpose # which is invoked from pci_hp_add_devices(). This new function # traverse_siblings_and_scan_slot() gets all the sibling bridge-ports by # traversal and explicitly invokes pci_scan_slot() on them. # # Tested-by: Shawn Anastasio # Signed-off-by: Krishna Kumar # [mpe: Move the code into pci-hotplug.c] # Signed-off-by: Michael Ellerman # Link: https://msgid.link/20240701074513.94873-3-krishnak@linux.ibm.com # < /opt/cross/kisskb/korg/gcc-13.1.0-nolibc/sparc64-linux/bin/sparc64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-13.1.0-nolibc/sparc64-linux/bin/sparc64-linux-ld --version # < git log --format=%s --max-count=1 20ce0c247b2500cb7060cb115274ba71abda2626 # make -s -j 160 ARCH=sparc64 O=/kisskb/build/powerpc-next_defconfig_sparc64-gcc13 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-13.1.0-nolibc/sparc64-linux/bin/sparc64-linux- defconfig # < make -s -j 160 ARCH=sparc64 O=/kisskb/build/powerpc-next_defconfig_sparc64-gcc13 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-13.1.0-nolibc/sparc64-linux/bin/sparc64-linux- help # make -s -j 160 ARCH=sparc64 O=/kisskb/build/powerpc-next_defconfig_sparc64-gcc13 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-13.1.0-nolibc/sparc64-linux/bin/sparc64-linux- olddefconfig # make -s -j 160 ARCH=sparc64 O=/kisskb/build/powerpc-next_defconfig_sparc64-gcc13 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-13.1.0-nolibc/sparc64-linux/bin/sparc64-linux- :1519:2: warning: #warning syscall clone3 not implemented [-Wcpp] /kisskb/src/arch/sparc/prom/p1275.c:52:6: warning: no previous prototype for 'prom_cif_init' [-Wmissing-prototypes] 52 | void prom_cif_init(void *cif_handler, void *cif_stack) | ^~~~~~~~~~~~~ /kisskb/src/arch/sparc/prom/misc_64.c:165:5: warning: no previous prototype for 'prom_get_mmu_ihandle' [-Wmissing-prototypes] 165 | int prom_get_mmu_ihandle(void) | ^~~~~~~~~~~~~~~~~~~~ /kisskb/src/arch/sparc/vdso/vclock_gettime.c:254:1: warning: no previous prototype for '__vdso_clock_gettime' [-Wmissing-prototypes] 254 | __vdso_clock_gettime(clockid_t clock, struct __kernel_old_timespec *ts) | ^~~~~~~~~~~~~~~~~~~~ /kisskb/src/arch/sparc/vdso/vclock_gettime.c:282:1: warning: no previous prototype for '__vdso_clock_gettime_stick' [-Wmissing-prototypes] 282 | __vdso_clock_gettime_stick(clockid_t clock, struct __kernel_old_timespec *ts) | ^~~~~~~~~~~~~~~~~~~~~~~~~~ /kisskb/src/arch/sparc/vdso/vclock_gettime.c:307:1: warning: no previous prototype for '__vdso_gettimeofday' [-Wmissing-prototypes] 307 | __vdso_gettimeofday(struct __kernel_old_timeval *tv, struct timezone *tz) | ^~~~~~~~~~~~~~~~~~~ /kisskb/src/arch/sparc/vdso/vclock_gettime.c:343:1: warning: no previous prototype for '__vdso_gettimeofday_stick' [-Wmissing-prototypes] 343 | __vdso_gettimeofday_stick(struct __kernel_old_timeval *tv, struct timezone *tz) | ^~~~~~~~~~~~~~~~~~~~~~~~~ /opt/cross/kisskb/korg/gcc-13.1.0-nolibc/sparc64-linux/bin/sparc64-linux-ld: warning: arch/sparc/vdso/vdso-note.o: missing .note.GNU-stack section implies executable stack /opt/cross/kisskb/korg/gcc-13.1.0-nolibc/sparc64-linux/bin/sparc64-linux-ld: NOTE: This behaviour is deprecated and will be removed in a future version of the linker In file included from /kisskb/src/arch/sparc/vdso/vdso32/vclock_gettime.c:22: /kisskb/src/arch/sparc/vdso/vdso32/../vclock_gettime.c:254:1: warning: no previous prototype for '__vdso_clock_gettime' [-Wmissing-prototypes] 254 | __vdso_clock_gettime(clockid_t clock, struct __kernel_old_timespec *ts) | ^~~~~~~~~~~~~~~~~~~~ /kisskb/src/arch/sparc/vdso/vdso32/../vclock_gettime.c:282:1: warning: no previous prototype for '__vdso_clock_gettime_stick' [-Wmissing-prototypes] 282 | __vdso_clock_gettime_stick(clockid_t clock, struct __kernel_old_timespec *ts) | ^~~~~~~~~~~~~~~~~~~~~~~~~~ /kisskb/src/arch/sparc/vdso/vdso32/../vclock_gettime.c:307:1: warning: no previous prototype for '__vdso_gettimeofday' [-Wmissing-prototypes] 307 | __vdso_gettimeofday(struct __kernel_old_timeval *tv, struct timezone *tz) | ^~~~~~~~~~~~~~~~~~~ /kisskb/src/arch/sparc/vdso/vdso32/../vclock_gettime.c:343:1: warning: no previous prototype for '__vdso_gettimeofday_stick' [-Wmissing-prototypes] 343 | __vdso_gettimeofday_stick(struct __kernel_old_timeval *tv, struct timezone *tz) | ^~~~~~~~~~~~~~~~~~~~~~~~~ /opt/cross/kisskb/korg/gcc-13.1.0-nolibc/sparc64-linux/bin/sparc64-linux-ld: warning: arch/sparc/vdso/vdso32/vdso-note.o: missing .note.GNU-stack section implies executable stack /opt/cross/kisskb/korg/gcc-13.1.0-nolibc/sparc64-linux/bin/sparc64-linux-ld: NOTE: This behaviour is deprecated and will be removed in a future version of the linker WARNING: modpost: EXPORT symbol "_mcount" [vmlinux] version generation failed, symbol will not be versioned.
