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:
