Jesse's provided some patches that disable some of the functionality without turning off the whole driver, which should still give most of the performance boost. There's also a couple of patches from Minskey to fix one or two register size issues and a potential NULL dereference. The following changes since commit 3c06806e690885ce978ef180c8f8b6f8c17fb4b4: Merge branch 'merge-powerpc' of git://git.secretlab.ca/git/linux-2.6 (2010-10-04 11:45:35 -0700) are available in the git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/mjg59/platform-drivers-x86.git for_linus Andy Whitcroft (1): intel_ips -- ensure we do not enable gpu turbo mode without driver linkage Jesse Barnes (4): IPS driver: don't toggle CPU turbo on unsupported CPUs IPS driver: verify BIOS provided limits IPS driver: apply BIOS provided CPU limit if different from default IPS driver: disable CPU turbo Matthew Garrett (1): IPS driver: Fix limit clamping when reducing CPU power Tim Gardner (1): intel_ips: Print MCP limit exceeded values. minskey guo (4): seqno mask of THM_ITV register is 16bit old_cpu_power is wrongly divided by 65535 in ips_monitor() Release symbol on error-handling path of ips_get_i915_syms() NULL pointer might be used in ips_monitor() drivers/platform/x86/intel_ips.c | 122 ++++++++++++++++++++++++++++---------- 1 files changed, 90 insertions(+), 32 deletions(-) -- Matthew Garrett | mjg59@srcf.ucam.org
