I applied the first three patches, will wait a bit for Ian and others to
have some time to look at it, but one thing I thought was that instead
of having parse_state->fake_pmu as a bool, you could have it as a
pointer to the fake pmu, this way we would do away with that static
thing in the middle of the parsing code.

+static int check_id(const char *id)
+{
+ struct parse_events_error error;
+ struct evlist *evlist;
+ int ret;
+
+ /* Numbers are always valid. */
+ if (is_number(id))
+ return 0;
+
+ evlist = evlist__new();
+ if (!evlist)
+ return -1;
+
+ memset(&error, 0, sizeof(error));
+ ret = parse_events_fake(evlist, id, &error);
+ if (ret) {
+ pr_debug("str : %s\n", error.str);
+ pr_debug("help : %s\n", error.help);
+ pr_debug("first_str : %s\n", error.first_str);
+ pr_debug("first_help : %s\n", error.first_help);
+ }
+
+ evlist__delete(evlist);
+ free(error.str);
+ free(error.help);
+ free(error.first_str);
+ free(error.first_help);
+ return ret;
+}


Would read:

struct perf_pmu fake = { 0, };
.
.
.
ret = parse_events_fake_pmu(evlist, id, &fake, &error);
.
.
.


That also renames parse_events_fake() to parse_events_fake_pmu().
