Hi Boris,
Thanks for the info. Unluckily, the _PDC method is not in these two SSDT tables, so let's search more place
for the _PDC method:
# acpidump > all.dat # dump all acpi binary data
# acpixtract all.dat # extract the DSDT, SSDT tables etc.
For each extracted table , please disassemble them:
# iasl -d xxxx.dat # e.g. iasl -d DSDT.dat
# grep "PDC" *.dsl #search _PDC in those disassemble files
If still no PDC is found, please search the "Load" command in those *.dsl files, usually the Load command has the following form:
OperationRegion (XXXX, SystemMemory, <address>, <length>)
Load(XXXX, handle)
Where XXXX indicates memory block of [address , address+length], in which _PDS is possibly in.
Then use acpidump to get those memory block:
# acpidump --addr <address> --length <length> --binary --output xxxx.dat
# iasl -d xxxx.dat
# grep "PDC" *.dsl # again
find the _PDC"
Once find the _PDC, please send out the *.dsl files.
Best Regards
Ke

It shows acpi_processor_set_pdc trying to access one BIOS memory or MMIO, but hypervisor fail to make the page mapping for this. But I still have no idea why this would happen.
When I try to find what the physical address is, I am a bit confused:
According to
the src code
acpi_ex_system_memory_space_handler(u32 function,
acpi_physical_address address,
u32 bit_width,
acpi_integer * value,
void *handler_context, void *region_context)
and the asm code
000000000024be4e <acpi_ex_system_memory_space_handler>:
24be4e: 55
push %rbp
24be4f: 48 89 e5 mov %rsp,%rbp
24be52: 41 57 push %r15
24be54: 49 89 cf mov %rcx,%r15
24be57: 41 56 push %r14
24be59: 41 89 d6 mov %edx,%r14d
24be5c: 41 55 push %r13
24be5e: 4d 89
cd mov %r9,%r13
24be61: 41 54 push %r12
24be63: 49 89 f4 mov %rsi,%r12 <------ R12 preserve RSI
24be66: 53 push %rbx
24be67: 48 83 ec 08 sub $0x8,%rsp
24be6b: 83 fa 10 cmp $0x10,%edx
the R12 preserve the RSI value, which is the second parameter "acpi_physical_address
address". However, the log shows R12=ffffc900117e0000 and it is more like a virtual address rather than a physical address.
or is it possible my asm code is different from Boris?
BTW, Boris, could you please also dump the ACPI SSDT table by:
# acpidump --addr 0xcff7e0d0 --length 0x277 --binary --output ssdt1.dat
# iasl -d ssdt1.dat # will generate ssdt1.asl
# acpidump --addr 0x cff7e350 --length 0x277 --binary --output ssdt2.dat
# iasl -d ssdt2.dat # will generate ssdt2.asl
And send out the ssdt1.asl and ssdt2.asl. in this case, we may be able to see which address the ACPI _PDC method want to access.
You can get iasl and acpidump from the following URL, in case you don't have it
acpidump:
