Subject: [PATCHv5 0/8] perf tool: parser generator for events parsing

hi,
here's new version of event parsing patchset.

I saw Arnaldo already sent patches 1-3 to Ingo, but they did not make it
to the tree yet, so I'm still attaching them here.

v5 changes:
4/8 - patch updated by Peter with actual format definitions
for x86 processors
6/8 - added hardcoded terms for config[12] and sample_period
the code is ready to include branch_sample_type once
this field is available in perf_event_attr, just
uncommenting one line.. ;)
- allow config option to be used without value in which
case 1 is assigned as value

Overall summarize:
- adding event parser bison/flex generator
- the event syntax stays as it was
- adding event format sysfs group attribute
for pmu device
- adding new syntax to specify raw events based
on the sysfs pmu's format attribute
eg. "cpu/config=1,config1=2,config2=3/u"

Attached patches:
1/8 perf, tool: Remove unused functions from debugfs object
2/8 perf, tool: Add sysfs mountpoint interface
3/8 perf, tool: Add bitmap_or function into bitmap object
4/8 perf: Adding sysfs group format attribute for pmu device
5/8 perf, tool: Add parser generator for events parsing
6/8 perf, tool: Add config options support for event parsing
7/8 perf, tool: Add perf pmu object to access pmu format definition
8/8 perf, tool: Add support to specify pmu style event

thanks,
jirka

Subject: [PATCH 3/8] perf, tool: Add bitmap_or function into bitmap object

Adding implementation os bitmap_or function to the bitmap
object. It is stolen from the kernel lib/bitmap.o object.

It is used in upcomming patches.

Changing event parsing to use flex/bison parse generator.

Added flex/bison files for event grammar parsing. The generated
parser is part of the patch. Added makefile rule 'event-parser'
to generate the parser code out of the bison/flex sources.

Subject: [PATCH 1/8] perf, tool: Remove unused functions from debugfs object

Following debugfs object functions are not referenced
within the code:

int debugfs_valid_entry(const char *path);
int debugfs_umount(void);
int debugfs_write(const char *entry, const char *value);
int debugfs_read(const char *entry, char *buffer, size_t size);
void debugfs_force_cleanup(void);
int debugfs_make_path(const char *element, char *buffer, int size);

Removing them.

[permalink] [raw]
Subject: [PATCH 7/8] perf, tool: Add perf pmu object to access pmu format definition

Adding pmu object which provides interface to pmu's sysfs
event format definition located at:
${sysfs_mount}/bus/event_source/devices/${pmu}/format

Following interface is exported:
struct perf_pmu* perf_pmu__find(char *name);
- this function returns pmu object, which is then
passed as a handle to other interface functions

int perf_pmu__config(struct perf_pmu *pmu, struct perf_event_attr *attr,
struct list_head *head_terms);
- this function configures perf_event_attr struct based
on pmu's format definitions and config terms data,
containined in head_terms list.

Parser generator is used to retrive the pmu's format definition.
The generated parser is part of the patch. Added makefile rule
'pmu-parser' to generate the parser code out of the bison/flex
sources.

Added builtin test 'Test perf pmu format parsing', which could
be run like:
perf test pmu

[permalink] [raw]
Subject: [PATCH 8/8] perf, tool: Add support to specify pmu style event

Added new event rule to the event definition grammar:

event_def: event_pmu |
...
event_pmu: PE_NAME '/' event_config '/'

Using this rule, event could be now specified like:
cpu/config=1,config1=2,config2=3/u

where pmu name 'cpu' is looked up via following path:
${sysfs_mount}/bus/event_source/devices/${pmu}

and config options are bound to the pmu's format definiton:
${sysfs_mount}/bus/event_source/devices/${pmu}/format

The hardcoded config options still stays and have precedence
over any format field defined with same name.

Subject: [PATCH 4/8] perf: Adding sysfs group format attribute for pmu device

Adding sysfs group 'format' attribute for pmu device that
contains a syntax description on how to construct raw events.

The event configuration is described in following
struct pefr_event_attr attributes:

config
config1
config2

Each sysfs attribute within the format attribute group,
describes mapping of name and bitfield definition within
one of above attributes.

eg:
"/sys/...<dev>/format/event" contains "config:0-7"
"/sys/...<dev>/format/umask" contains "config:8-15"
"/sys/...<dev>/format/usr" contains "config:16"

the attribute value syntax is:

line: config ':' bits
config: 'config' | 'config1' | 'config2"
bits: bits ',' bit_term | bit_term
bit_term: VALUE '-' VALUE | VALUE

Adding format attribute definitions for x86 cpu pmus.

+Description:
+ Attribute group to describe the magic bits that go into
+ perf_event_attr::config[012] for a particular pmu.
+ Each attribute of this group defines the 'hardware' bitmask
+ we want to export, so that userspace can deal with sane
+ name/value pairs.
+
+ Example: 'config1:1,6-10,44'
+ Defines contents of attribute that occupies bits 1,6-10,44 of
+ perf_event_attr::config1.

Subject: [PATCH 2/8] perf, tool: Add sysfs mountpoint interface

Adding sysfs object to provide sysfs mount information
in the same way as debugfs object does.

The object provides following function:
sysfs_find_mountpoint

which returns the sysfs mount mount.

[permalink] [raw]
Subject: [PATCH 6/8] perf, tool: Add config options support for event parsing

Adding a new rule to the event grammar to be able to specify
values of additional attributes of symbolic event.

The new syntax for event symbolic definition is:

event_legacy_symbol: PE_NAME_SYM '/' event_config '/' |
PE_NAME_SYM sep_slash_dc

event_config: event_config ',' event_term | event_term

event_term: PE_NAME '=' PE_NAME |
PE_NAME '=' PE_VALUE
PE_NAME

sep_slash_dc: '/' | ':' |

At the moment the config options are hardcoded to be used for legacy
symbol events to define several perf_event_attr fields. It is:

'config' to define perf_event_attr::config
'config1' to define perf_event_attr::config1
'config2' to define perf_event_attr::config2
'period' to define perf_event_attr::sample_period

Legacy events could be now specified as:
cycles/period=100000/

If term is specified without the value assignment, then 1 is
assigned by default.

I'm fine with this going fwd, and since this is mostly tools/perf I
suggest acme take it, so:

look and merge the rest, adding your a-b.
