This causes all new # architecture features to be made available when running on newer # processors with new architecture features added to the PCR as bits # must be set to disable a given feature. # # For example to disable new features added as part of Version 2.07 of # the ISA the corresponding bit in the PCR needs to be set. # # As new processor features generally require explicit kernel support # they should be disabled until such support is implemented. Therefore # kernels should set all unknown/reserved bits in the PCR such that any # new architecture features which the kernel does not currently know # about get disabled. # # An update is planned to the ISA to clarify that the PCR is an # exception to the Programming Note on reserved bits in Section 1.3.3. # # Signed-off-by: Jordan Niethe # [alistair: Added some clarifications to the commit message] # Signed-off-by: Alistair Popple # Tested-by: Joel Stanley # Signed-off-by: Michael Ellerman # Link: https://lore.kernel.org/r/20190910060102.21597-1-alistair@popple.id.au # < /opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux-ld --version # < git log --format=%s --max-count=1 516627be26024f9952005a3116cbdb9d6dc24428 # < make -s -j 32 ARCH=powerpc O=/kisskb/build/powerpc-next_85xx_mpc85xx_cds_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- 85xx/mpc85xx_cds_defconfig # make -s -j 32 ARCH=powerpc O=/kisskb/build/powerpc-next_85xx_mpc85xx_cds_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- /kisskb/src/arch/powerpc/boot/dts/fsl/mpc8541cds.dts:330.3-21: Warning (pci_device_bus_num): /pci@e0008000/i8259@19000:bus-range: PCI bus number 1 out of range, expected (0 - 0) /kisskb/src/arch/powerpc/boot/dts/fsl/mpc8555cds.dts:330.3-21: Warning (pci_device_bus_num): /pci@e0008000/i8259@19000:bus-range: PCI bus number 1 out of range, expected (0 - 0) INFO: Uncompressed kernel (size 0x5169a0) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) INFO: Uncompressed kernel (size 0x5169a0) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) INFO: Uncompressed kernel (size 0x5169a0) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) INFO: Uncompressed kernel (size 0x506278) overlaps the address of the wrapper(0x400000) INFO: Fixing the link_address of wrapper to (0x600000) Image Name: Linux-5.3.0-rc2-g516627be2602 Created: Sat Sep 14 02:12:24 2019 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 2634050 Bytes = 2572.31 KiB = 2.51 MiB Load Address: 00000000 Entry Point: 00000000 Image Name: Linux-5.3.0-rc2-g516627be2602 Created: Sat Sep 14 02:12:24 2019 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 2664166 Bytes = 2601.72 KiB = 2.54 MiB Load Address: 00600000 Entry Point: 006002a4 Image Name: Linux-5.3.0-rc2-g516627be2602 Created: Sat Sep 14 02:12:24 2019 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 2663324 Bytes = 2600.90 KiB = 2.54 MiB Load Address: 00600000 Entry Point: 006002a4 Image Name: Linux-5.3.0-rc2-g516627be2602 Created: Sat Sep 14 02:12:24 2019 Image Type: PowerPC Linux Kernel Image (gzip compressed) Data Size: 2663325 Bytes = 2600.90 KiB = 2.54 MiB Load Address: 00600000 Entry Point: 006002a4 Completed OK # rm -rf /kisskb/build/powerpc-next_85xx_mpc85xx_cds_defconfig_powerpc-gcc5 # Build took: 0:00:46.478062
