[PATCH 0/8] perf tools: add symbol filter to struct machine

[PATCH 0/8] perf tools: add symbol filter to struct machine

[Adrian Hunter]

Hi

Here are some patches that add symbol filter to struct machine as
we briefly discussed on irc.

The first patch puts the symbol filter on both struct machine and
struct machines so that guest machines added later inherit the same
symbol filter.

The next 4 patches change the tools to set the machines symbol filter.

The final 3 patches remove symbol filter as a parameter in some cases
where it is redundant.

[PATCH 1/8] perf tools: add symbol filter to struct machine

[Adrian Hunter]

The symbol filter needs to be applied machine-wide, so
add it to struct machine.

Currently tools pass the symbol filter as a parameter to
various map-related functions.  However a need to load a
map can occur anywhere in the code, at which point the
filter is needed.

[PATCH 8/8] perf tools: remove filter parameter of thread__find_addr_map()

[Adrian Hunter]

Now that the symbol filter is recorded on the machine
there is no need to pass it to thread__find_addr_map().
So remove it.

perf machine: Add symbol filter to struct machine

The symbol filter needs to be applied machine-wide, so add it to struct
machine.

Currently tools pass the symbol filter as a parameter to various
map-related functions.  However a need to load a map can occur anywhere
in the code, at which point the filter is needed.
