I ever sent the patch 1 in the link: https://patchwork.kernel.org/project/linux-riscv/patch/20220708073150.352830-3-xianting.tian@xxxxxxxxxxxxxxxxx/ And patch 2,3 in the link: https://patchwork.kernel.org/project/linux-riscv/patch/20220714113300.367854-2-xianting.tian@xxxxxxxxxxxxxxxxx/ https://patchwork.kernel.org/project/linux-riscv/patch/20220714113300.367854-3-xianting.tian@xxxxxxxxxxxxxxxxx/ This patch set just put these patches together, and with three new patch 4, 5, 6. these six patches are the fixups for machine_kexec, kernel mode PC for vmcore and improvements for vmcoreinfo, memory layout dump and fixup chedule out issue in machine_crash_shutdown(). The main changes in the six patchs as below, Patch 1: use __smp_processor_id() instead of smp_processor_id() to cleanup the console prints. Patch 2: Add VM layout, va bits, ram base to vmcoreinfo, which can simplify the development of crash tool as ARM64 already did (arch/arm64/kernel/crash_core.c). Patch 3: Add modules to virtual kernel memory layout dump. Patch 4: Fixup to get correct kernel mode PC for vmcore. Patch 5: Updates vmcoreinfo.rst. Patch 6: Fixup schedule out issue in machine_crash_shutdown() With these six patches(patch 2 is must), crash tool can work well to analyze a vmcore. The patches for crash tool for RISCV64 is in the link: https://lore.kernel.org/linux-riscv/20220801043040.2003264-1-xianting.tian@xxxxxxxxxxxxxxxxx/ ------ Changes v1 -> v2: 1, remove the patch "Add a fast call path of crash_kexec()" from this series of patches, as it already applied to riscv git. https://git.kernel.org/pub/scm/linux/kernel/git/riscv/linux.git/commit/?h=for-next&id=3f1901110a89b0e2e13adb2ac8d1a7102879ea98 2, add 'Reviewed-by' based on the comments of v1. Changes v2 -> v3: use "riscv" instead of "riscv64" in patch 5 subject line. Changes v3 -> v4: use "riscv" instead of "riscv64" in the summary of patch 5 subject line. Changes v4 -> v5: add a new patch "RISC-V: Fixup schedule out issue in machine_crash_shutdown()" Xianting Tian (6): RISC-V: use __smp_processor_id() instead of smp_processor_id() RISC-V: Add arch_crash_save_vmcoreinfo support riscv: Add modules to virtual kernel memory layout dump RISC-V: Fixup getting correct current pc riscv: crash_core: Export kernel vm layout, phys_ram_base RISC-V: Fixup schedule out issue in machine_crash_shutdown() .../admin-guide/kdump/vmcoreinfo.rst | 31 +++++++++++++++++++ arch/riscv/kernel/Makefile | 1 + arch/riscv/kernel/crash_core.c | 29 +++++++++++++++++ arch/riscv/kernel/crash_save_regs.S | 2 +- arch/riscv/kernel/machine_kexec.c | 28 ++++++++++++++--- arch/riscv/mm/init.c | 4 +++ 6 files changed, 89 insertions(+), 6 deletions(-) create mode 100644 arch/riscv/kernel/crash_core.c -- 2.17.1
