[Bug 684888] Re: Update intel_idle driver
** Description changed: SRU Justification: We periodically provide updated drivers to provide additional support for hardware and provide bug fixes. The intel_idle is a cpuidle driver that loads on specific Intel processors in lieu of the legacy ACPI processor_idle driver. The intent is to make Linux more efficient on these processors, as intel_idle knows more than ACPI, as well as make Linux more immune to ACPI BIOS bugs. As we now support HW that can leverage the intel_idle driver, it's advantageous to provide an updated version of the driver for those interested in it's use. All of the - patches are already upstream as well (see details below) and were even - suggested as a stable release by the upstream maintainer. + patches are already upstream as well (see details below). I'd originally pursued providing this update via linux-bcakports- modules. However, testing proved that because the acpi_idle driver is built into the kernel, it prevents the intel_idle driver from loading later on via LBM. This is because the core cpuidle driver is not capable of handling run-time changing of idle drivers. + I would also like to note that these patches were originally submitted to upstream stable by the upstream maintainer. However, the submission + was later retracted due to the fact that some of the patches are cosmetic in nature. See: + + git://git.kernel.org/pub/scm/linux/kernel/git/lenb/linux- + idle-2.6.35.y.git idle-release + Impact: - These patches should only affect the intel_idle driver. It will also only load on supported systems. This driver can also be disabled by booting with intel_idle.max_cstate=0 which disables intel_idle and the system will fall back on ACPI's acpi_idle. + + These patches should only affect the intel_idle driver.
