From 948cf67c4726cca2fc57533dccadfb54d890689d Mon Sep 17 00:00:00 2001 From: Benjamin Herrenschmidt Date: Mon, 24 Jan 2011 18:42:41 +1100 Subject: powerpc: Add NAP mode support on Power7 in HV mode Wakeup comes from the system reset handler with a potential loss of the non-hypervisor CPU state. We save the non-volatile state on the stack and a pointer to it in the PACA, which the system reset handler uses to restore things Signed-off-by: Benjamin Herrenschmidt --- arch/powerpc/include/asm/paca.h | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'arch/powerpc/include/asm/paca.h') diff --git a/arch/powerpc/include/asm/paca.h b/arch/powerpc/include/asm/paca.h index ec57540..f6da4f5 100644 --- a/arch/powerpc/include/asm/paca.h +++ b/arch/powerpc/include/asm/paca.h @@ -125,7 +125,7 @@ struct paca_struct { struct task_struct *__current; /* Pointer to current */ u64 kstack; /* Saved Kernel stack addr */ u64 stab_rr; /* stab/slb round-robin counter */ - u64 saved_r1; /* r1 save for RTAS calls */ + u64 saved_r1; /* r1 save for RTAS calls or PM */ u64 saved_msr; /* MSR saved here by enter_rtas */ u16 trap_save; /* Used when bad stack is encountered */ u8 soft_enabled; /* irq soft-enable flag */ -- cgit v1.1
