Idle=poll

The log seems fine, the kernel modulo is compiled properly. When the CPU core is needed to run programs, it is sent an interrupt to wake up and it moves from whatever C-state it is in to C0. error=-1 04-27 10:17:48.172 498 932 E lights : gpc: value=70 (Mode=1) 04-27 10:17:51.172 498 932 E lights : gpc: value=250 (Mode=1) 04-27 10:17:51.492 18373 18373 E libBlurEffect: AndroidBitmap_getInfo() failed !

And the performance as slightly faster than the "HT-enabled, cstates enabled" case.

Linux Disable C-states

I also recall reading somewhere that with the intel_idle driver C1 is set automatically (even with latency=0) and this is starting to make a lot more sense. https://software.intel.com/en-us/forums/software-tuning-performance-optimization-platform-monitoring/topic/535130 You signed in with another tab or window. Idle=poll I could disable the C-states using a small program that I copied from the powertop manual that keeps the dma_latency file open and sets the latency to 0. Acpi_idle Vs Intel_idle Any insights would be deeply appreciated.

A couple of ideas that might help clarify what is happening: Try the same experiment with HyperThreading ("logical processors") disabled. We Acted. But I see it got fixed in the last version. Not sure why this doesn't work for you. Idle=mwait

Summary: Modern processors power management features can cause unwanted delays in time-sensitive application processing by transitioning your processors into power-saving C-states.

Booting with 'idle=poll' turns off cstates.

I changed one method signature and broke 25,000 other classes. I'm using VirtualBox-5.0.4-102546-Linux_amd64.run (generic). Turbostat showed for both cases that the frequency was 1.5Ghz. /dev/network_latency This corresponds to a transition between no C-states at all and C1.

Details: Modern processors such as Intel's Nehalem-based processors are very aggressive about transitioning into power-saving states. Writing a maximum allowable latency of 0 will keep the processors in C0" I can't read the file cpu_dma_latency. The no 'idle=poll' case had no time in c3, c6 or c7 but it did have time in c1, sometimes one of the HT threads of each core was 100% in The phone gets unresponsive, with sometimes a FC of the phone app.

Periodically on a multicore system, the workloads being run will align so that many of the cores are simultaneously idle and therefore transitioning to deeper C-states. Forgot your password?
