Subject: [PATCH 30/38] tools lib traceevent: Add xen plugin
Date: Wed, 4 Dec 2013 17:06:54 -0300 [thread overview]
Message-ID: <1386187622-2928-31-git-send-email-acme@infradead.org> (raw)
In-Reply-To: <1386187622-2928-1-git-send-email-acme@infradead.org>
From: Jiri Olsa <jolsa@redhat.com>
Adding xen plugin.
This plugin adds fields resolving for following tracepoint events:
xen:xen_mc_entry
xen:xen_mc_extend_args
The diff of 'perf script' output generated by old and new code: (data
was generated by 'perf record -e 'xen:*' ls')
--- script.xen.old
+++ script.xen.new
- swapper 0 [002] 136.267492: xen:xen_mc_entry: [FAILED TO PARSE] op=3 nargs=2 args=ARRAY[18, 00, 00, 00, 00, 00, 00, 00, 00, e0, d4, 4b, 04, 88, ff, ff, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00, 00]
+ swapper 0 [002] 136.267492: xen:xen_mc_entry: op 3(stack_switch) args [18, 0, 0, 0, 0, 0]
- perf 1970 [008] 136.273319: xen:xen_mc_extend_args: [FAILED TO PARSE] op=1 args=16 res=1
+ perf 1970 [008] 136.273319: xen:xen_mc_extend_args: extending op 1(mmu_update) by 16 bytes res ???
NOTE We still do not handle the 'sizeof' and fail to parse following xen
tracepoints:
xen:xen_mmu_set_pte
xen:xen_mmu_set_pte_atomic
xen:xen_mmu_set_domain_pte
xen:xen_mmu_set_pte_at
xen:xen_mmu_set_pmd
xen:xen_mmu_set_pud
xen:xen_mmu_set_pgd
xen:xen_mmu_ptep_modify_prot_start
xen:xen_mmu_ptep_modify_prot_commit
