Naga Chumbalkar ded1f6ab43 x86: print APIC data a little later during boot ... To view IOAPIC data you could boot with "apic=debug". When booting in such a way then the kernel will dump the IO-APIC's registers, for example: NR Dst Mask Trig IRR Pol Stat Dmod Deli Vect: 00 000 1 0 0 0 0 0 0 00 01 000 0 0 0 0 0 0 0 31 02 000 0 0 0 0 0 0 0 30 03 000 0 0 0 0 0 0 0 33 04 000 0 0 0 0 0 0 0 34 05 000 0 0 0 0 0 0 0 35 06 000 0 0 0 0 0 0 0 36 07 000 0 0 0 0 0 0 0 37 08 000 0 0 0 0 0 0 0 38 09 000 0 1 0 0 0 0 0 39 0a 000 0 0 0 0 0 0 0 3A 0b 000 0 0 0 0 0 0 0 3B 0c 000 0 0 0 0 0 0 0 3C 0d 000 0 0 0 0 0 0 0 3D 0e 000 0 0 0 0 0 0 0 3E 0f 000 0 0 0 0 0 0 0 3F 10 000 1 0 0 0 0 0 0 00 11 000 1 0 0 0 0 0 0 00 12 000 1 0 0 0 0 0 0 00 13 000 1 0 0 0 0 0 0 00 14 000 1 0 0 0 0 0 0 00 15 000 1 0 0 0 0 0 0 00 16 000 1 0 0 0 0 0 0 00 17 000 1 0 0 0 0 0 0 00 Delaying the call to print_ICs() gives better results: NR Dst Mask Trig IRR Pol Stat Dmod Deli Vect: 00 000 1 0 0 0 0 0 0 00 01 000 0 0 0 0 0 0 0 31 02 000 0 0 0 0 0 0 0 30 03 000 1 0 0 0 0 0 0 33 04 000 1 0 0 0 0 0 0 34 05 000 1 0 0 0 0 0 0 35 06 000 1 0 0 0 0 0 0 36 07 000 1 0 0 0 0 0 0 37 08 000 0 0 0 0 0 0 0 38 09 000 0 1 0 0 0 0 0 39 0a 000 1 0 0 0 0 0 0 3A 0b 000 1 0 0 0 0 0 0 3B 0c 000 0 0 0 0 0 0 0 3C 0d 000 1 0 0 0 0 0 0 3D 0e 000 1 0 0 0 0 0 0 3E 0f 000 1 0 0 0 0 0 0 3F 10 000 1 1 0 1 0 0 0 29 11 000 1 0 0 0 0 0 0 00 12 000 1 0 0 0 0 0 0 00 13 000 1 0 0 0 0 0 0 00 14 000 0 1 0 1 0 0 0 51 15 000 1 0 0 0 0 0 0 00 16 000 0 1 0 1 0 0 0 61 17 000 0 1 0 1 0 0 0 59 Notice that the entries beyond interrupt input signal 0x0f also get populated and arent just the hw-initialization default of all zeroes.
