Consolidate the memory block size device tree parsing # to one helper and use that on both powernv and pseries. We still want to # use machine-specific callback because on all machine types other than # powernv and pseries we continue to return MIN_MEMORY_BLOCK_SIZE. # # pseries_memory_block_size used to look for the second memory # block (memory@x) to determine the memory_block_size value. This patch # changed that to look at all memory blocks and make sure we can map them all # correctly using the computed memory block size value. # # Add workaround to force 256MB memory block size if device driver managed # memory such as GPU memory is present. This helps to add GPU memory # that is not aligned to 1G. # # Co-developed-by: Reza Arbab # Signed-off-by: Reza Arbab # Signed-off-by: "Aneesh Kumar K.V" # Signed-off-by: Michael Ellerman # Link: https://msgid.link/20230801044447.11275-1-aneesh.kumar@linux.ibm.com # < /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 c56963d48343b50998bacc6df949217c950163e3 # make -s -j 40 ARCH=powerpc O=/kisskb/build/powerpc-next_wii_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- wii_defconfig # < make -s -j 40 ARCH=powerpc O=/kisskb/build/powerpc-next_wii_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- help # make -s -j 40 ARCH=powerpc O=/kisskb/build/powerpc-next_wii_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- olddefconfig # make -s -j 40 ARCH=powerpc O=/kisskb/build/powerpc-next_wii_defconfig_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- Completed OK # rm -rf /kisskb/build/powerpc-next_wii_defconfig_powerpc-gcc5 # Build took: 0:00:43.885157
