Re: Call for testing: x2apic

[murray%river-styx.org@localhost]

Hi Folks,
   With the suggested addition of support for x2apic, the x2apic enable
flag in the IA32_APIC_BASE MSR register could be added to
sys/arch/x86/include/i82489reg.h... for completeness of register
documentation at least, even if not used.

    ...as documented in the Intel 64 and IA32 Architectures Software
Developers Manual 3A, chapter 10.5.1.
