From b65ce83f2a607ad478c5492812f5f218e8d57a6b Mon Sep 17 00:00:00 2001 From: Len Brown Date: Fri, 18 Nov 2016 01:23:17 -0500 Subject: i7300_idle: Remove this driver In preparation for removing the idle_notifier, remove its only user, the i7300_idle driver. i7300_idle was deployed in 2008 to reduce idle memory power on systems using the i7300 chipset. The driver worked by throttling the fully-buffered DIMMs during idle periods using the IOAT DMA engine. The driver ran only on the i7300 chip-set, and no other hardware has used this mechanism. The driver no longer has a maintainer. Removing this driver will increase idle power on i7300 systems when they run the new kernel without the driver.
