Execute a subprogram on all CPUs simultaneously.
ACPI_STATUS AcpiExecSMPFunction (ACPIRUNATALLCPU SubProgram, UINT32 CPUMask, UINT32 Flags, void *Context)
Parameters
- SubProgram
- Address subprogram, which called in each CPU according with CPUMask, must declare as ACPI_STATUS APIENTRY SubProgram(void *Context)
- CPUMask
- CPUs for execute, low word is bit field, where bit number is number of CPU for execute, 0xffffffff mean "all CPU"
- Flags
- Flag, can be:
- SMPEXEC_IPITIME
- run from IPI (interrupt time) , stack is NOT OS/2 stack
- SMPEXEC_TASKTIME
- run from PSD_SET_PROC_STATE, PSD stack, kernel time
- SMPEXEC_WBINDVD
- Flush cache at all CPU, parameter SubProgram ignore with this.
- SMPEXEC_SYNC
- synchronize CPU before run (now tested with SMPEXEC_TASKTIME )
- Context
- Context which passed as parameter to SubProgram
- Note
- In Uni kernel call imeditialy w/o any checking CPU number. Running in kernel time.
