Subject: [PATCH 11/23] perf probe: Fix wrong register name for arm64
Date: Wed, 25 Jan 2017 10:53:38 -0300 [thread overview]
Message-ID: <20170125135350.22983-12-acme@kernel.org> (raw)
In-Reply-To: <20170125135350.22983-1-acme@kernel.org>
From: He Kuang <hekuang@huawei.com>
The register name of arm64 architecture is x0-x31 not r0-r31, this patch
changes this typo.
Before this patch:
# perf probe --definition 'sys_write count'
p:probe/sys_write _text+1502872 count=%r2:s64
# echo 'p:probe/sys_write _text+1502872 count=%r2:s64' > \
/sys/kernel/debug/tracing/kprobe_events
Parse error at argument[0]. (-22)
After this patch:
# perf probe --definition 'sys_write count'
p:probe/sys_write _text+1502872 count=%x2:s64
# echo 'p:probe/sys_write _text+1502872 count=%x2:s64' > \
/sys/kernel/debug/tracing/kprobe_events
# echo 1 >/sys/kernel/debug/tracing/events/probe/enable
# cat /sys/kernel/debug/tracing/trace
...
sh-422 [000] d... 650.495930: sys_write: (SyS_write+0x0/0xc8) count=22
sh-422 [000] d... 651.102389: sys_write: (SyS_write+0x0/0xc8) count=26
sh-422 [000] d... 651.358653: sys_write: (SyS_write+0x0/0xc8) count=86
