I ever sent the patch 1 in the link:
https://patchwork.kernel.org/project/linux-riscv/patch/20220708073150.352...
And patch 2,3 in the link:
https://patchwork.kernel.org/project/linux-riscv/patch/20220714113300.367...
https://patchwork.kernel.org/project/linux-riscv/patch/20220714113300.367...
This patch series just put these patches together, and with two new patch 4, 5.
these five patches are the fixups for machine_kexec, kernel mode PC for vmcore
and improvements for vmcoreinfo and memory layout dump.
The main changes in the five 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.
With these 5 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/20220718025346.411758-1-xianting.tian...
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...
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.
Xianting Tian (5):
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

New subject: [PATCH V4 1/5] RISC-V: use __smp_processor_id() instead of smp_processor_id()
Use __smp_processor_id() to avoid check the preemption context when
CONFIG_DEBUG_PREEMPT enabled, as we will enter crash kernel and no
return.

New subject: [PATCH V4 2/5] RISC-V: Add arch_crash_save_vmcoreinfo support
Add arch_crash_save_vmcoreinfo(), which exports VM layout(MODULES, VMALLOC,
VMEMMAP and KERNEL_LINK_ADDR ranges), va bits and ram base to vmcore.
Default pagetable levels and PAGE_OFFSET aren't same for different kernel
version as below. For default pagetable levels, it sets sv57 on defaultly
in latest kernel and do fallback to try to set sv48 on boot time if sv57
is not supported in current hardware.
For ram base, the default value is 0x80200000 for qemu riscv64 env, 0x200000
for riscv64 SoC platform(eg, SoC platform of RISC-V XuanTie 910 CPU).
* Linux Kernel 5.18 ~
* PGTABLE_LEVELS = 5
* PAGE_OFFSET = 0xff60000000000000
* Linux Kernel 5.17 ~
* PGTABLE_LEVELS = 4
* PAGE_OFFSET = 0xffffaf8000000000
* Linux Kernel 4.19 ~
* PGTABLE_LEVELS = 3
* PAGE_OFFSET = 0xffffffe000000000
Since these configurations change from time to time and version to version,
it is preferable to export them via vmcoreinfo than to change the crash's
code frequently, it can simplify the development of crash tool.

New subject: [PATCH V4 3/5] riscv: Add modules to virtual kernel memory layout dump
Modules always live before the kernel, MODULES_END is fixed but
MODULES_VADDR isn't fixed, it depends on the kernel size.
Let's add it to virtual kernel memory layout dump.
As MODULES is only defined for CONFIG_64BIT, so we dump it when
CONFIG_64BIT=y.
eg,
MODULES_VADDR - MODULES_END
0xffffffff01133000 - 0xffffffff80000000

New subject: [PATCH V4 4/5] RISC-V: Fixup getting correct current pc
When use 'echo c > /proc/sysrq-trigger' to trigger kdump,
riscv_crash_save_regs()
will be called to save regs to vmcore, we found "epc" value 00ffffffa5537400
is not a valid kernel virtual address, but is a user virtual address. Other
regs(eg, ra, sp, gp...) are correct kernel virtual address.
Actually 0x00ffffffb0dd9400 is the user mode PC of 'PID: 113 Comm: sh', which
is saved in the task's stack.

Ah I see you've already sent a v4.
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...
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.
There's no need to respin a series for the sake 3 characters in the cover
letter (so sorry if you misunderstood me!)...
Xianting Tian (5):
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
...but it would've been good to align these to either "riscv:" or
"RISC-V:" & not mix the two in a series. Don't do this right away,
it is okay to wait for more significant changes before sending out
a new version as this sort of thing could easily be changed when
being applied.
Thanks,
Conor.

Many thanks, I got it, waiting these patches to be applied:)
Thanks,
