unable to write into Local APIC registers
...small kernel (setting up the IDT, GDT n all)
Im disabling 8259 and enabling Local APIC but im unable to write into
Local APIC registers . can anyone tell me is there something which im
missing
?
Here is my piece of code
SVR EQU 0FEE000F0H ; define the Spurious interrupt vector
APIC_ENABLE EQU 100H
;disable 8259
MOV AL,0FFH
OUT 0A1H, AL
OUT 021H, AL
;enable local apic and set the spurious interrupt vector
MOV ESI,SVR
MOV EAX,<ESI>
OR EAX,APIC_ENABLE
MOV <ESI>,EAX
Warm regards,
Ravi Kulkarni.

[PATCH 0/2] Hyper-V synthetic interrupt controller
This patchset implements the KVM part of the synthetic interrupt
controller (synic) which is a building block of the Hyper-V
paravirtualized device bus (vmbus).
Synic is a lapic extension, which is controlled via MSRs and maintains
for each vCPU
- 16 synthetic interrupt "lines" (SINT's); each can be configured to
trigger a specific interrupt vector optionally with auto-EOI
