linux-linaro-2.6.39 does not have DVFS Framework itself. So cpufreq is not expected to work on 2.6.39 linaro kernel.
I applied this patch against 2.6.38 linaro kernel and I do see that l3 clock is properly scaling when I change mpu frequency via cpufreq sysfs entries. Note that bogomips does not show MPU Rate properly because of an issue in cpufreq non SMP plafroms with SMP Enabled in menuconfig. But if you read the actual clock rate (using below sysfs entry), you see that MPU clock is scaling. mount -t debugfs debugfs /debug cat /debug/clock/virt_26m_ck/osc_sys_ck/sys_ck/dpll1_ck/dpll1_x2_ck/dpll1_x2m2 _ck/mpu_ck/arm_fck/rate -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/784176 Title: CPU_FREQ support is broken for OMAP 3 and OMAP 4 To manage notifications about this bug go to: https://bugs.launchpad.net/linux-linaro/+bug/784176/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
