I'd like to hear back from you what the best practice is to get the job done.

Thanks, Luming ---------- Forwarded message ---------- From: Luming Yu Date: Tue, May 29, 2012 at 4:37 AM Subject: [patch] a simple hardware detector for latency as well as throughput ver. 0.1.0 To: jcm@jonmasters.org Cc: linux-kernel@vger.kernel.org Hi Jon, The patch is the fist step to test some basic hardware functions like TSC to help people understand if there is any hardware latency as well as throughput problem exposed on bare metal or left behind by BIOS or interfered by SM. Currently the patch tests hardware features (tsc,freq, and rdrandom whiich is new instruction to get random number) in stop_machine context. I will add more after the first step get merged for those guys who want to directly play with new hardware functions. I suppose I can add your signed-off-by as the code is derived from your hwlat_dector. I'm also reuqesting if you are going to queue it up somewhere that can be pulled into 3.5. Of cause, I will update the patch based upon any comments that you think must be fixed for 3.5 merge.
