Hi,
Im new to this group.
I want to get some information from BIOS. i.e i want to know whether Hyperthreading is Enabled/Disabled(as per BIOS settings) from an user applications program.
there is no standard way to do this. You can use /proc/cpuinfo to see if
the kernel found ht'd processors. But that's the best you can do.
(well you could grovel through the acpi tables just like the kernel
does, but you really don't want to do that from userspace)
How to read ACPI tables ? Can you give little info on this...
even from Driver program, if its possible please tell me...
