Resolves: https://issues.redhat.com/browse/RHEL-77215 Upstream: kdump-utils Conflict: manually apply commit 4f7970eefa6cba5d7cebd739718fb947a3fedbad (HEAD -> main, origin/main, origin/HEAD) Author: Sourabh Jain <sourabhjain@linux.ibm.com> Date: Thu Dec 4 13:51:21 2025 +0530 powerpc: Set nr_cpus=16 for kdump kernel Configure the kdump kernel with nr_cpus=16 to enable multi-threading in the makedumpfile core collector, allowing faster dump collection. Commit d428557fc2b59 ("Use all available CPUs to collect dump") introduced multi-threading support in the core collector. There are two reasons for choosing nr_cpus=16: - Multiple experiments show that optimal performance is achieved when nr_cpus is between 16 and 30. The graph in commit d428557fc2b59 supports this. - nr_cpus=16 is already used for the fadump kernel, so using the same value for kdump to maintain consistency. Signed-off-by: Sourabh Jain <sourabhjain@linux.ibm.com> Since there is no gen-kdump-sysconfig.sh in RHEL-9 kexec-tools, and the patch just change the nr_cpus from 1 to 16, so apply it manually.
