BLTK FAQ
What is BLTK used for? Battery life measurements for laptops require repeatable workloads. While BAPCo MobileMark* 2005 is widely used in the industry, it runs only on Microsoft Windows* platform. Intel’s Open Source Technology Center has developed a battery life measurement toolkit, to make reliable battery life measurements on Linux with no special lab equipment necessary. How do I install bltk? Refer to the README document under the doc directory, once you have untarred the BLTK tarball. How do I check if I have bltk installed properly? Please issue “make check” to check all the workloads, or, to check individual workloads:
How do I run BLTK? To start running BLTK, use the bltk command issued by the make check routine as a starting point. Use “bltk –h” to find more options. Can I specify a limited number of times to run a workload? Yes, use the “--show-num n” option to run the workload “n” number of times and “--show-time t” to run the workload for “t” sec in each iteration. Make sure you allow enough time for a workload iteration to complete. These options are useful if you are using BLTK to provide load to a system and you are measuring power externally. Where can I find the run results? Look in this directory: “<workload_name>.results”. Something has gone wrong during the test run, what should I do? Look in the “err.log” and “work_out.log” files of the result directory. They will usually contain relevant error messages. Where can I find more information about BLTK? Look at the paper, by BLTK author, Len Brown. It can be downloaded from: http://ftp.kernel.org/pub/linux/kernel/people/lenb/acpi/doc/OLS2006-bltk-paper.pdf |
