From 4944930ab748942e41ea4dc313fcb0946aee3f17 Mon Sep 17 00:00:00 2001 From: Stephane Eranian Date: Mon, 25 Apr 2005 13:08:30 -0700 Subject: [IA64] perfmon: make pfm_sysctl a global, and other cleanup - make pfm_sysctl a global such that it is possible to enable/disable debug printk in sampling formats using PFM_DEBUG. - remove unused pfm_debug_var variable - fix a bug in pfm_handle_work where an BUG_ON() could be triggered. There is a path where pfm_handle_work() can be called with interrupts enabled, i.e., when TIF_NEED_RESCHED is set. The fix correct the masking and unmasking of interrupts in pfm_handle_work() such that we restore the interrupt mask as it was upon entry. signed-off-by: stephane eranian Signed-off-by: Tony Luck --- include/asm-ia64/perfmon.h | 12 ++++++++++++ 1 file changed, 12 insertions(+) (limited to 'include/asm-ia64') diff --git a/include/asm-ia64/perfmon.h b/include/asm-ia64/perfmon.h index 136c60e..ed5416c 100644 --- a/include/asm-ia64/perfmon.h +++ b/include/asm-ia64/perfmon.h @@ -254,6 +254,18 @@ extern int pfm_mod_write_dbrs(struct task_struct *task, void *req, unsigned int #define PFM_CPUINFO_DCR_PP 0x2 /* if set the system wide session has started */ #define PFM_CPUINFO_EXCL_IDLE 0x4 /* the system wide session excludes the idle task */ +/* + * sysctl control structure. visible to sampling formats + */ +typedef struct { + int debug; /* turn on/off debugging via syslog */ + int debug_ovfl; /* turn on/off debug printk in overflow handler */ + int fastctxsw; /* turn on/off fast (unsecure) ctxsw */ + int expert_mode; /* turn on/off value checking */ +} pfm_sysctl_t; +extern pfm_sysctl_t pfm_sysctl; + + #endif /* __KERNEL__ */ #endif /* _ASM_IA64_PERFMON_H */ -- cgit v1.1
