From c223c90386bc2306510e0ceacd768a0123ff2a2f Mon Sep 17 00:00:00 2001 From: Christophe Leroy Date: Tue, 17 May 2016 08:33:46 +0200 Subject: powerpc32: provide VIRT_CPU_ACCOUNTING This patch provides VIRT_CPU_ACCOUTING to PPC32 architecture. PPC32 doesn't have the PACA structure, so we use the task_info structure to store the accounting data. In order to reuse on PPC32 the PPC64 functions, all u64 data has been replaced by 'unsigned long' so that it is u32 on PPC32 and u64 on PPC64 Signed-off-by: Christophe Leroy Signed-off-by: Scott Wood --- arch/powerpc/kernel/asm-offsets.c | 23 +++++++++++++++++++---- 1 file changed, 19 insertions(+), 4 deletions(-) (limited to 'arch/powerpc/kernel/asm-offsets.c') diff --git a/arch/powerpc/kernel/asm-offsets.c b/arch/powerpc/kernel/asm-offsets.c index 5b99f956e32f..047892869257 100644 --- a/arch/powerpc/kernel/asm-offsets.c +++ b/arch/powerpc/kernel/asm-offsets.c @@ -240,13 +240,28 @@ int main(void) DEFINE(PACAHWCPUID, offsetof(struct paca_struct, hw_cpu_id)); DEFINE(PACAKEXECSTATE, offsetof(struct paca_struct, kexec_state)); DEFINE(PACA_DSCR_DEFAULT, offsetof(struct paca_struct, dscr_default)); - DEFINE(PACA_STARTTIME, offsetof(struct paca_struct, starttime)); - DEFINE(PACA_STARTTIME_USER, offsetof(struct paca_struct, starttime_user)); - DEFINE(PACA_USER_TIME, offsetof(struct paca_struct, user_time)); - DEFINE(PACA_SYSTEM_TIME, offsetof(struct paca_struct, system_time)); + DEFINE(ACCOUNT_STARTTIME, + offsetof(struct paca_struct, accounting.starttime)); + DEFINE(ACCOUNT_STARTTIME_USER, + offsetof(struct paca_struct, accounting.starttime_user)); + DEFINE(ACCOUNT_USER_TIME, + offsetof(struct paca_struct, accounting.user_time)); + DEFINE(ACCOUNT_SYSTEM_TIME, + offsetof(struct paca_struct, accounting.system_time)); DEFINE(PACA_TRAP_SAVE, offsetof(struct paca_struct, trap_save)); DEFINE(PACA_NAPSTATELOST, offsetof(struct paca_struct, nap_state_lost)); DEFINE(PACA_SPRG_VDSO, offsetof(struct paca_struct, sprg_vdso)); +#else /* CONFIG_PPC64 */ +#ifdef CONFIG_VIRT_CPU_ACCOUNTING_NATIVE + DEFINE(ACCOUNT_STARTTIME, + offsetof(struct thread_info, accounting.starttime)); + DEFINE(ACCOUNT_STARTTIME_USER, + offsetof(struct thread_info, accounting.starttime_user)); + DEFINE(ACCOUNT_USER_TIME, + offsetof(struct thread_info, accounting.user_time)); + DEFINE(ACCOUNT_SYSTEM_TIME, + offsetof(struct thread_info, accounting.system_time)); +#endif #endif /* CONFIG_PPC64 */ /* RTAS */ -- cgit v1.2.3
