| * | | | | | | | | | | x86: HPET_MSI Initialise per-cpu HPET timersvenkatesh.pallipadi@intel.com2008-10-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Initialize a per CPU HPET MSI timer when possible. We retain the HPET timer 0 (IRQ 0) and timer 1 (IRQ 8) as is when legacy mode is being used. We setup the remaining HPET timers as per CPU MSI based timers. This per CPU timer will eliminate the need for timer broadcasting with IRQ 0 when there is non-functional LAPIC timer across CPU deep C-states. If there are more CPUs than number of available timers, CPUs that do not find any timer to use will continue using LAPIC and IRQ 0 broadcast.

APIC_RRR is a reserved register except for 82489DX, APIC for Pentium processors. APIC_EOI is a write only register. APIC_DFR is reserved in x2apic mode. Access to these registers in x2apic will result in #GP fault. Fix these apic register accesses.
