New package: cache-calibrator The Calibrator is a small C program that is supposed to analyze a computers (cache-) memory system and extract the following parameters: number of cache levels for each cache level: its size its linesize its access/miss latency main memory access latency number of TLB levels for each TLB level: its capacity (i.e. number of entries) the pagesize used the TLB miss latency http://homepages.cwi.nl/~manegold/Calibrator/ It is also recommended as a load generator for realtime testing in: https://rt.wiki.kernel.org/index.php/RT_PREEMPT_HOWTO#Benchmarking [Peter: reformat help text, fix extract step] Signed-off-by: Stephan Hoffmann <sho@relinux.de> Acked-by: Arnout Vandecappelle (Essensium/Mind) <arnout@mind.be> Signed-off-by: Peter Korsgaard <jacmet@sunsite.dk>

package/cache-calibrator: fix legal-info Fixes: http://autobuild.buildroot.net/results/e1b/e1b3dee917f5ab3961f3dea006720431444d0ef5/ cache-calibrator is a single C file that is downloaded as-is, and we patch it. We also use that file as the license file. Thus, the file when it is downloaded has a specific hash, but when saved by legal-info, it has a different hash. However, we can't store two different hashes for the same _filename_ with different content. So, we extract the license file as a pre-patch hook, and store it in a separate file, for which we can now add a hash.
