Mumble server having issues?

So I've been having trouble with the mumble server and the behavior is odd enough that I don't think its a problem just on my end. I'm seeing cases where: * Only one of two members in a room can hear me talk * One member could hear both parties talking * I can't hear either of them talk As well

[PATCH v3 0/5] ARM: topology: set the capacity of each cores for big.LITTLE

This patchset creates an arch_scale_freq_power function for ARM, which is used to set the relative capacity of each core of a big.LITTLE system. It also removes the broken power estimation of x86. Modification since v2: - set_power_scale function becomes static - Rework loop in update_siblings

Re: [PATCH] [CPUFREQ] VCPUfreq: Virtual CPU frequency driver.

Hi Charles, At first I did looked in the hrtimers API to do so, but it seems that significant hacking would be required to provide what is needed for vcpufreq to work; That is: 1) Steering of the timer interrupt to a given CPU 2) Making sure that the timer callback is called in an interrupt conte

[PATCH v5] ARM: imx: Add basic imx6q cpu thermal management

Add imx6q cpu thermal management driver using the new cpu cooling interface which limits system performance via cpufreq to reduce the cpu temperature. Temperature readings are taken using the imx6q temperature sensor and this functionality was added as part of this cpu thermal management driver.
