To save typing on the switch char set slang stuff. It also helps in removing more slang direct calls, wrapping them at the ui_browser level, where at some point I'll try to implement those in terms of GTK+.

Use cpu-clock-tick sw counter for cpu-cycles only if there is no hw pmu available. This is the case if the syscall reports ENOENT. In other cases (e.g. invalid attributes) we don't want the sw counter to be used.

Currently the parsers objects (bison/flex related) are each time perf is built. No matter the generated files are already in place, the parser generation is executed every time. Changing the rules to have proper flex/bison objects generation dependencies. The parsers code is not rebuilt until the flex/bison source files are touched.

Now you can do $ make tools/<toolname> from the toplevel kernel directory and have the respective tool built. If you want to build and install it, do $ make tools/<toolname>_install $ make tools/<toolname>_clean should clean the respective tool directories. If you want to clean all in tools, simply do $ make tools/clean Also, if you want to get what the possible targets are, simply calling $ make tools/ should give you the short help. $ make tools/install installs all tools, of course.

This patch prints the number of samples and the count of performance events separately. This allows comparing performance of different applications with each other. Previously, the sample count was displayed against an 'Events:' heading. With this patch, the header now reads (for example): Samples: 5K of event 'instructions' Event count (approx.): 2993026545 The patch covers both the stdio and the browser interface. Signed-off-by:

Now it is possible to press ENTER or -> (right arrow) on jump instructions to navigate to the offset it points to. More work needed to support <- to go back, i.e. a jump history. This is done just like the callq case, i.e. parsing objdump output lines, but should move to use Masami's disassembler at some point. Suggested-by:
