Mike Smith c3c50c4e3a Further fixes for multiple-IO-APIC systems from Tor Egge: ... Further experimentation showed that some Dell 2450 machines with the prevention kludge installed still got T_RESERVED traps. CPU interrupt vector 0x7A was observed to be triggered. This might have been the bitwise OR of two different vectors sent from each of the IOAPICs at the same time. IOAPIC #0: 0x68 --> irq 8: RTC timer interrupt IOAPIC #1: 0x32 --> irq 18: scsi host adapter or network interface ---- 0x7a --> T_RESERVED Both IOAPICs had ID 0. Appendix B.3 in the MP spec indicates that the operating system is responsible for assigning unique IDs to the IOAPICs. The enclosed patch programs the IOAPIC IDs according to the IOAPIC entries in the MP table. Submitted by: tegge		2000-05-31 21:37:28 +00:00
