List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , X-List-Received-Date: Fri, 24 Jan 2014 04:31:57 -0000 Hi, I was wondering if it is possible to adjust the CPU frequency on the Raspberry Pi under FreeBSD 10.0-RELEASE? I've been trying to find what the clock is currently set at using sysctl but I cannot seem to find any values that show the frequency. I also checked the FreeBSD kernel source and did not see any related tunable aside from hw.bcm2835.min_freq. Is this the tunable I would use? Thanks, Jordan
