From: Len Brown Date: Thu, 14 Jun 2012 02:12:51 +0000 (-0400) Subject: ACPI: acpi_pad: tune round_robin_time X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=fa7584e13ac8e6a306085bba0a931f3135f1d8c4;p=linux-beck.git ACPI: acpi_pad: tune round_robin_time In an effort to be fair to bound processes, acpi_pad periodically moves its forced-idle threads. The default interval for moving the threads is 10 seconds. Measurements show that reducing this to 1 second has no power or performance impact, so reduce default to 1 second.
