* - * Notes on locking strategy: - * - * Most Falcon registers require 16-byte (or 8-byte, for SRAM - * registers) atomic writes which necessitates locking. - * Under normal operation few writes to the Falcon BAR are made and these - * registers (EVQ_RPTR_REG, RX_DESC_UPD_REG and TX_DESC_UPD_REG) are special - * cased to allow 4-byte (hence lockless) accesses. - * - * It *is* safe to write to these 4-byte registers in the middle of an - * access to an 8-byte or 16-byte register. We therefore use a - * spinlock to protect accesses to the larger registers, but no locks - * for the 4-byte registers. - * - * A write barrier is needed to ensure that DW3 is written after DW0/1/2 - * due to the way the 16byte registers are "collected" in the Falcon BIU - * - * We also lock when carrying out reads, to ensure consistency of the - * data (made possible since the BIU reads all 128 bits into a cache). - * Reads are very rare, so this isn't a significant performance - * impact. (Most data transferred from NIC to host is DMAed directly - * into host memory). - * - * I/O BAR access uses locks for both reads and writes (but is only provided - * for testing purposes). - */ - -/* Special buffer descriptors (Falcon SRAM) */ -#define BUF_TBL_KER_A1 0x18000 -#define BUF_TBL_KER_B0 0x800000 - - -#if BITS_PER_LONG == 64 -#define FALCON_USE_QWORD_IO 1 -#endif - -#ifdef FALCON_USE_QWORD_IO -static inline void _falcon_writeq(struct efx_nic *efx, __le64 value, - unsigned int reg) -{ - __raw_writeq((__force u64)value, efx->membase + reg); -} -static inline __le64 _falcon_readq(struct efx_nic *efx, unsigned int reg) -{ - return (__force __le64)__raw_readq(efx->membase + reg); -} -#endif - -static inline void _falcon_writel(struct efx_nic *efx, __le32 value, - unsigned int reg) -{ - __raw_writel((__force u32)value, efx->membase + reg); -} -static inline __le32 _falcon_readl(struct efx_nic *efx, unsigned int reg) -{ - return (__force __le32)__raw_readl(efx->membase + reg); -} - -/* Writes to a normal 16-byte Falcon register, locking as appropriate. */ -static inline void falcon_write(struct efx_nic *efx, efx_oword_t *value, - unsigned int reg) -{ - unsigned long flags; - - EFX_REGDUMP(efx, "writing register %x with " EFX_OWORD_FMT "\n", reg, - EFX_OWORD_VAL(*value)); - - spin_lock_irqsave(&efx->biu_lock, flags); -#ifdef FALCON_USE_QWORD_IO - _falcon_writeq(efx, value->u64[0], reg + 0); - wmb(); - _falcon_writeq(efx, value->u64[1], reg + 8); -#else - _falcon_writel(efx, value->u32[0], reg + 0); - _falcon_writel(efx, value->u32[1], reg + 4); - _falcon_writel(efx, value->u32[2], reg + 8); - wmb(); - _falcon_writel(efx, value->u32[3], reg + 12); -#endif - mmiowb(); - spin_unlock_irqrestore(&efx->biu_lock, flags); -} - -/* Writes to an 8-byte Falcon SRAM register, locking as appropriate. */ -static inline void falcon_write_sram(struct efx_nic *efx, efx_qword_t *value, - unsigned int index) -{ - unsigned int reg = efx->type->buf_tbl_base + (index * sizeof(*value)); - unsigned long flags; - - EFX_REGDUMP(efx, "writing SRAM register %x with " EFX_QWORD_FMT "\n", - reg, EFX_QWORD_VAL(*value)); - - spin_lock_irqsave(&efx->biu_lock, flags); -#ifdef FALCON_USE_QWORD_IO - _falcon_writeq(efx, value->u64[0], reg + 0); -#else - _falcon_writel(efx, value->u32[0], reg + 0); - wmb(); - _falcon_writel(efx, value->u32[1], reg + 4); -#endif - mmiowb(); - spin_unlock_irqrestore(&efx->biu_lock, flags); -} - -/* Write dword to Falcon register that allows partial writes - * - * Some Falcon registers (EVQ_RPTR_REG, RX_DESC_UPD_REG and - * TX_DESC_UPD_REG) can be written to as a single dword.

It reads and processes the input file and +displays the results of the trace analysis implemented in the given +Perl script, if any. + +STARTER SCRIPTS +--------------- + +You can avoid reading the rest of this document by running 'perf trace +-g perl' in the same directory as an existing perf.data trace file. +That will generate a starter script containing a handler for each of +the event types in the trace file; it simply prints every available +field for each event in the trace file. + +You can also look at the existing scripts in +~/libexec/perf-core/scripts/perl for typical examples showing how to +do basic things like aggregate event data, print results, etc. Also, +the check-perf-trace.pl script, while not interesting for its results, +attempts to exercise all of the main scripting features. + +EVENT HANDLERS +-------------- + +When perf trace is invoked using a trace script, a user-defined +'handler function' is called for each event in the trace. If there's +no handler function defined for a given event type, the event is +ignored (or passed to a 'trace_handled' function, see below) and the +next event is processed. + +Most of the event's field values are passed as arguments to the +handler function; some of the less common ones aren't - those are +available as calls back into the perf executable (see below). + +As an example, the following perf record command can be used to record +all sched_wakeup events in the system: + + # perf record -c 1 -f -a -M -R -e sched:sched_wakeup + +Traces meant to be processed using a script should be recorded with +the above options: -c 1 says to sample every event, -a to enable +system-wide collection, -M to multiplex the output, and -R to collect +raw samples. + +The format file for the sched_wakep event defines the following fields +(see /sys/kernel/debug/tracing/events/sched/sched_wakeup/format): + +---- + format: + field:unsigned short common_type; + field:unsigned char common_flags; + field:unsigned char common_preempt_count; + field:int common_pid; + field:int common_lock_depth; + + field:char comm[TASK_COMM_LEN]; + field:pid_t pid; + field:int prio; + field:int success; + field:int target_cpu; +---- + +The handler function for this event would be defined as: + +---- +sub sched::sched_wakeup +{ + my ($event_name, $context, $common_cpu, $common_secs, + $common_nsecs, $common_pid, $common_comm, + $comm, $pid, $prio, $success, $target_cpu) = @_; +} +---- + +The handler function takes the form subsystem::event_name. + +The $common_* arguments in the handler's argument list are the set of +arguments passed to all event handlers; some of the fields correspond +to the common_* fields in the format file, but some are synthesized, +and some of the common_* fields aren't common enough to to be passed +to every event as arguments but are available as library functions. + +Here's a brief description of each of the invariant event args: + + $event_name the name of the event as text + $context an opaque 'cookie' used in calls back into perf + $common_cpu the cpu the event occurred on + $common_secs the secs portion of the event timestamp + $common_nsecs the nsecs portion of the event timestamp + $common_pid the pid of the current task + $common_comm the name of the current process + +All of the remaining fields in the event's format file have +counterparts as handler function arguments of the same name, as can be +seen in the example above. + +The above provides the basics needed to directly access every field of +every event in a trace, which covers 90% of what you need to know to +write a useful trace script.

Context.pm contains the Perl->C +interface that allows scripts to access data in the embedding perf +executable; scripts wishing to do that should 'use Context.pm'. + +The Perl->C perf interface is completely driven by Context.xs. If you +want to add new Perl functions that end up accessing C data in the +perf executable, you add desciptions of the new functions here. +scripting_context is a pointer to the perf data in the perf executable +that you want to access - it's passed as the second parameter, +$context, to all handler functions. + +After you do that: + + perl Makefile.PL # to create a Makefile for the next step +
