List-Id: "Xenomai life and development \(bug reports, patches, discussions\)" List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , To: Xenomai core Hi, I run clocktest on a system here, not running NTP, using CONFIG_GENERIC_CLOCKEVENT, with a systematic drift of 3us/s. How can this happen? Does it come from the error due to the multiply and shift used for tsc to/from ns conversions ? TIA, -- Gilles.
