Assign IRQs to HPET Timers
"
in x86.git
cause my servers hang
after
Calling initcall 0xffffffff80b9a465: hpet_late_init+0x0/0x100()
after reverting that I got:
initcall 0xffffffff80b947d1 ran for 19 msecs: pci_iommu_init+0x0/0x13()
Calling initcall 0xffffffff80b9a465: hpet_late_init+0x0/0x100()
hpet0: at MMIO 0xfed00000, IRQs 2, 8, 31
hpet0: 3 32-bit timers, 25000000 Hz
initcall 0xffffffff80b9a465: hpet_late_init+0x0/0x100() returned 0.
initcall 0xffffffff80b9a465 ran for 7 msecs: hpet_late_init+0x0/0x100()
CPU0 CPU1 CPU2 CPU3 CPU4 CPU5
CPU6 CPU7
0: 86 0 0 0 0 0
1 0 IO-APIC-edge timer
4: 0 0 0 0 0 0
1 838 IO-APIC-edge serial
7: 1 0 0 0 0 0
0 0 IO-APIC-edge
8: 0 0 0 0 0 0
0 0 IO-APIC-edge rtc0
for mcp55, it should already route hpet to ioapic pin2 or the irq0.
