Therefore, updating the fadump implementation documentation # to reflect those changes. # # Following updates are done to firmware assisted dump documentation: # # 1. The elfcorehdr is no longer stored after fadump HDR in the reserved # dump area. Instead, the second kernel dynamically allocates memory # for the elfcorehdr within the address range from 0 to the boot memory # size. Therefore, update figures 1 and 2 of Memory Reservation during # the first and second kernels to reflect this change. # # 2. A version field has been added to the fadump header to maintain # backward compatibility without changing the fadump header magic # number in the future. Therefore, remove the corresponding TODO from # the document. # # To: linuxppc-dev@lists.ozlabs.org # Signed-off-by: Sourabh Jain # Signed-off-by: Michael Ellerman # Link: https://msgid.link/20231021181733.204311-4-sourabhjain@linux.ibm.com # < /opt/cross/kisskb/korg/gcc-12.2.0-nolibc/powerpc64-linux/bin/powerpc64-linux-gcc --version # < /opt/cross/kisskb/korg/gcc-12.2.0-nolibc/powerpc64-linux/bin/powerpc64-linux-ld --version # < git log --format=%s --max-count=1 5e69d465457215225178b3003d70e556c6c42ea0 # make -s -j 32 ARCH=powerpc O=/kisskb/build/powerpc-next_powernv_defconfig_powerpc-gcc12 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-12.2.0-nolibc/powerpc64-linux/bin/powerpc64-linux- powernv_defconfig # < make -s -j 32 ARCH=powerpc O=/kisskb/build/powerpc-next_powernv_defconfig_powerpc-gcc12 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-12.2.0-nolibc/powerpc64-linux/bin/powerpc64-linux- help # make -s -j 32 ARCH=powerpc O=/kisskb/build/powerpc-next_powernv_defconfig_powerpc-gcc12 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-12.2.0-nolibc/powerpc64-linux/bin/powerpc64-linux- olddefconfig # make -s -j 32 ARCH=powerpc O=/kisskb/build/powerpc-next_powernv_defconfig_powerpc-gcc12 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-12.2.0-nolibc/powerpc64-linux/bin/powerpc64-linux- Completed OK # rm -rf /kisskb/build/powerpc-next_powernv_defconfig_powerpc-gcc12 # Build took: 0:03:14.858335
