Subject: [PATCH] x86: fix wakeup_cpu with numaq/es7000
Date: Sun, 16 Nov 2008 00:47:38 -0800 [thread overview]
Message-ID: <491FDE2A.1010809@kernel.org> (raw)
Impact: fix wakeup path with numaq and es7000
while looking at wakeup_secondary_cpu for WAKE_SECONDARY_VIA_NMI
|#ifdef WAKE_SECONDARY_VIA_NMI
|/*
| * Poke the other CPU in the eye via NMI to wake it up. Remember that the normal
| * INIT, INIT, STARTUP sequence will reset the chip hard for us, and this
| * won't ... remember to clear down the APIC, etc later.
| */
|static int __devinit
|wakeup_secondary_cpu(int logical_apicid, unsigned long start_eip)
|{
| unsigned long send_status, accept_status = 0;
| int maxlvt;
|...
| if (APIC_INTEGRATED(apic_version[phys_apicid])) {
| maxlvt = lapic_get_maxlvt();
there is no warning about undefined phys_apicid...
because WAKE_SECONDARY_VIA_NMI and WAKE_SECONDARY_VIA_NMI can not be defined
at the same time. so NUMAQ is using wrong wakeup_secondary_cpu.
so add wakeup_secondary_cup in x86_quirks
need to add functions in wakecpu.h to genapic for 32bit.
while looking further, about functions in wakecup.h for numaq and es7000 is
different to default to mach_wakecpu.h. but smpboot.c will only use default
mach_wakecpu.h with smphook.h
So need to add mach_wakecpu.h for mach_generic to support numaq and es7000.
