I'm trying to enable high resolution timer support on 2.6.39.1 64-bit Linux. To do this, I first set CONFIG_HIGH_RES_TIMERS=y in .config. Also, the output of grep HZ .config is: #

High-Resolution Timers. 06/16/2017; 4 minutes to read; In this article. Starting with Windows 8.1, drivers can use the ExXxxTimer routines to manage high-resolution timers. The accuracy of a high-resolution timer is limited only by the maximum supported resolution of the system clock.

I want to have a timer with about 5millisecond resolution. but the current Timer in .Net has a resolution of about 50ms. I could not find any working solution that creates a high resolution timer, although some claim that you can do it in C#.

This ensures also that a kernel which is configured for high resolution timers can run on a system which lacks the necessary hardware support. The high resolution timer code does not support SMP machines which have only global clock event devices. The support of such hardware would involve IPI calls when an interrupt happens.

The timer wheel code is very good and tight code, there’s zero problems with it in its current usage - but it is simply not suitable to be extended for high-res timers. the unpredictable [O(N)] overhead of cascading leads to delays which necessitate a more complex handling of high resolution timers, which in turn decreases robustness.

High resolution timers . The high resolution patch is maintained by small group of core developers, led by Thomas Gleixner.It allows precise timed scheduling and removes the dependency of timers on the periodic scheduler tick (jiffies). Thomas and Ingo wrote high resolution timer design notes which explain the implementation details.. Since 2.6.24-rc1 the high resolution timer patch are fully ...

May 13, 2019 · One more time: CONFIG_HIGH_RES_TIMERS only enables the upper-half of the framework. By itself this is not sufficient to obtain better resolutions. The bottom half is a driver for the (faster) timer hardware. One more time: All you have to do is use the kernel configuration sama5_defconfig, and you will automatically have 1ns high resolution timers.
