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-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 5e69d465457215225178b3003d70e556c6c42ea0 # make -s -j 40 ARCH=powerpc O=/kisskb/build/powerpc-next_pseries_defconfig+FA_DUMP_powerpc-gcc5 CROSS_COMPILE=/opt/cross/kisskb/korg/gcc-5.5.0-nolibc/powerpc64-linux/bin/powerpc64-linux- pseries_defconfig Using /kisskb/src/arch/powerpc/configs/ppc64_defconfig as base Merging /kisskb/src/arch/powerpc/configs/le.config Merging /kisskb/src/arch/powerpc/configs/guest.config Value of CONFIG_VIRTIO_BLK is redefined by fragment /kisskb/src/arch/powerpc/configs/guest.config: Previous value: CONFIG_VIRTIO_BLK=m New value: CONFIG_VIRTIO_BLK=y Value of CONFIG_SCSI_VIRTIO is redefined by fragment /kisskb/src/arch/powerpc/configs/guest.config: Previous value: CONFIG_SCSI_VIRTIO=m New value: CONFIG_SCSI_VIRTIO=y Value of CONFIG_VIRTIO_NET is redefined by fragment /kisskb/src/arch/powerpc/configs/guest.config: Previous value: CONFIG_VIRTIO_NET=m New value: CONFIG_VIRTIO_NET=y Value of CONFIG_VIRTIO_CONSOLE is redefined by fragment /kisskb/src/arch/powerpc/configs/guest.config: Previous value: CONFIG_VIRTIO_CONSOLE=m New value: CONFIG_VIRTIO_CONSOLE=y Value of CONFIG_VIRTIO_PCI is redefined by fragment /kisskb/src/arch/powerpc/configs/guest.config: Previous value: CONFIG_VIRTIO_PCI=m New value: CONFIG_VIRTIO_PCI=y Value of CONFIG_VIRTIO_BALLOON is redefined by fragment /kisskb/src/arch/powerpc/configs/guest.config: Previous value: CONFIG_VIRTIO_BALLOON=m New value: CONFIG_VIRTIO_BALLOON=y Value of CONFIG_VHOST_NET is redefined by fragment /kisskb/src/arch/powerpc/configs/guest.config: Previous value: CONFIG_VHOST_NET=m New value: CONFIG_VHOST_NET=y Value of CONFIG_IBMVETH is redefined by fragment /kisskb/src/arch/powerpc/configs/guest.config: Previous value: CONFIG_IBMVETH=m New value: CONFIG_IBMVETH=y Value of CONFIG_IBMVNIC is redefined by fragment /kisskb/src/arch/powerpc/configs/guest.config: Previous value: CONFIG_IBMVNIC=m New value: CONFIG_IBMVNIC=y Merging /kisskb/src/arch/powerpc/configs/kvm_guest.config # # merged configuration written to .config (needs make) # # Added to kconfig CONFIG_CRASH_DUMP=y # Added to kconfig CONFIG_FA_DUMP=y # < make -s -j 40 ARCH=powerpc O=/kisskb/build/powerpc-next_pseries_defconfig+FA_DUMP_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_pseries_defconfig+FA_DUMP_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_pseries_defconfig+FA_DUMP_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_pseries_defconfig+FA_DUMP_powerpc-gcc5 # Build took: 0:01:59.344618
