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 In order to reuse on PPC32 the PPC64 functions, all u64 data has been replaced by 'unsigned long' so that it is u32 on PPC32 and u64 on PPC64 Signed-off-by: Christophe Leroy Signed-off-by: Scott Wood --- arch/powerpc/include/asm/ppc_asm.h | 24 ++++++++++++------------ 1 file changed, 12 insertions(+), 12 deletions(-) (limited to 'arch/powerpc/include/asm/ppc_asm.h') diff --git a/arch/powerpc/include/asm/ppc_asm.h b/arch/powerpc/include/asm/ppc_asm.h index 7b591f98edcc..96b06dc93b4c 100644 --- a/arch/powerpc/include/asm/ppc_asm.h +++ b/arch/powerpc/include/asm/ppc_asm.h @@ -24,27 +24,27 @@ */ #ifndef CONFIG_VIRT_CPU_ACCOUNTING_NATIVE -#define ACCOUNT_CPU_USER_ENTRY(ra, rb) -#define ACCOUNT_CPU_USER_EXIT(ra, rb) +#define ACCOUNT_CPU_USER_ENTRY(ptr, ra, rb) +#define ACCOUNT_CPU_USER_EXIT(ptr, ra, rb) #define ACCOUNT_STOLEN_TIME #else -#define ACCOUNT_CPU_USER_ENTRY(ra, rb) \ +#define ACCOUNT_CPU_USER_ENTRY(ptr, ra, rb) \ MFTB(ra); /* get timebase */ \ - ld rb,PACA_STARTTIME_USER(r13); \ - std ra,PACA_STARTTIME(r13); \ + PPC_LL rb, ACCOUNT_STARTTIME_USER(ptr); \ + PPC_STL ra, ACCOUNT_STARTTIME(ptr); \ subf rb,rb,ra; /* subtract start value */ \ - ld ra,PACA_USER_TIME(r13); \ + PPC_LL ra, ACCOUNT_USER_TIME(ptr); \ add ra,ra,rb; /* add on to user time */ \ - std ra,PACA_USER_TIME(r13); \ + PPC_STL ra, ACCOUNT_USER_TIME(ptr); \ -#define ACCOUNT_CPU_USER_EXIT(ra, rb) \ +#define ACCOUNT_CPU_USER_EXIT(ptr, ra, rb) \ MFTB(ra); /* get timebase */ \ - ld rb,PACA_STARTTIME(r13); \ - std ra,PACA_STARTTIME_USER(r13); \ + PPC_LL rb, ACCOUNT_STARTTIME(ptr); \ + PPC_STL ra, ACCOUNT_STARTTIME_USER(ptr); \ subf rb,rb,ra; /* subtract start value */ \ - ld ra,PACA_SYSTEM_TIME(r13); \ + PPC_LL ra, ACCOUNT_SYSTEM_TIME(ptr); \ add ra,ra,rb; /* add on to system time */ \ - std ra,PACA_SYSTEM_TIME(r13) + PPC_STL ra, ACCOUNT_SYSTEM_TIME(ptr) #ifdef CONFIG_PPC_SPLPAR #define ACCOUNT_STOLEN_TIME \ -- cgit v1.2.3
