Hi Folks, I have two questions about discovering the processors from the MADT table.
Firstly, Can we find out which processor is the BSP from the MADT tables? When comparing the userland mptable binary's output versus acpidump's output I noticed that mptable informs us about which processor is the BSP and which are AP's . However I did not see this in the MADT tables. Is there a way to find out which processor is the BSP by means of any of the ACPI tables. Secondly, Can we write into /dev/mem to say update the contents of MPTable with values that are non -default. I plan to read some values from the ACPI tables and update the MP tables. Is the /dev/mem/ file composed of physical addresses for user space memory ? I know this may not qualify as the correct place to ask,but I guess acpi list might have an answer to this.
