Fix perf-probe to show probe definition on gcc generated symbols
for offline kernel (including cross-arch kernel image).
Gcc sometimes optimizes functions and generate new symbols with
suffixes such as ".constprop.N" or ".isra.N" etc. Since those
symbol names are not recorded in DWARF, we have to
Hi Kim,
Although the blocks of that file will finally be discarded when it is not
current segment any more and almost fully invalidate,
but the point is that the blocks of that file can only be discarded along with
the whole segment now, which violates the meaning
of small discard. Look at th
Fix to probe on gcc generated functions on modules. Since
probing on a module is based on its symbol name, it should
be adjusted on actual symbols.
E.g. without this fix, perf probe shows probe definition
on non-exist symbol as below.
-
$ perf probe -m build-x86_64/net/netfilter/nf_nat.ko
When power management is disabled in the kernel configuration compiler
will complain that st_irq_syscfg_resume is defined but not used. Wrap
the function definition with CONFIG_PM_SLEEP as per other users of
SIMPLE_DEV_PM_OPS.

Fix --funcs (-F) option to show correct symbols for
offline module. Since previous perf-probe uses
machine__findnew_module_map() for offline module,
even if user passes a module file (with full path)
which is for other architecture, perf-probe always
tries to load symbol map for current kernel modu
Hello,
This series fixes some issues on offline module/cross-arch
probe support. While I was debuging arm32 kernel with
cross-arch perf-probe, I found several issues.
- perf-probe didn't show correct probe definition on
gcc-generated symbols (on both of kernel and module).
- perf-probe didn't s
Use a local dev variable instead of dereferencing pdev->dev several
times in the probe function to make the code easier to read.

Checking if there is no error followed by a goto if there is one is
confusing. Reverse the logic.

Enabling the clock before accessing chip registers and disabling it
afterwards does not really make sense and only adds complexity to
the driver. In addition to that, a comment int the driver suggests
that it does not serve a useful purpose either.
"The watchdog block is of course always clocked,
