Hi Yoshinoya,

 

The MP Services UEFI proto= col has been used to run the CPUID instructions on a given CPU core and to = read / write the MSRs from given CPU core.

The python functions for t= his purpose are supported from the edk2module built in extension module are= respectively cpuid_ex, rdmsr_ex/  wrmsr_ex with the function signatures as g= iven below.

 

cupid_ex has the following= signature cpuid_ex(= cpu, eax, ecx) -> (eax:ebx:ecx:edx)

rdmsr_ex(cpu, msr) -> (lower_32bits,= higher_32bits)

wrmsr_ex(cpu, msr, lower_32bits, higher= _32bits) -> None

 

where the cpu parameter= refers to the cpu core number starting from 0, 0 being BSP.

 

The usage instructions and= code sample are not yet updated in the wiki. I can add more details at the= earliest.

 

Please use the edk2-libc d= iscussions page for any further questions / discussions.<= /p>

JP

hi, JP

Got it, thank you!

 

I found some uefi mp service functions's= call sample in edk2module.c

 

So, user could follow this sample and wr= ite multi process sample with python script ? 

 

best wishes,

Hi, Michael

I  am studying Python368 uefi code.

I have a question, ask for help.

 

I found some marco defines in edk2module.c

"HAVE_FORK / HAVE_FORK1 / HAVE_SPAWNV /= etc"

 

It seems about multi-thread support function= s, 

so my question is:

1. Have these functions been tested on uefi = shell environments?

2. Are there any code samples for study how = to use them?

 

Thank you very much.<= /o:p>
