x86/asm/entry/32, selftests: Add a selftest for kernel entries from VM86 mode

2015-05-30T08:21:32Z

Test a couple of special cases in 32-bit kernels for entries from vm86 mode. This will OOPS both old kernels due to a bug and and 4.1-rc5 due to a regression I introduced, and it should make sure that the SYSENTER-from-vm86-mode hack in the kernel keeps working.

tools/power turbostat: allow running without cpu0

2015-05-27T22:04:01Z

Linux-3.7 added CONFIG_BOOTPARAM_HOTPLUG_CPU0, allowing systems to offline cpu0. But when cpu0 is offline, turbostat will not run: # turbostat ls turbostat: no /dev/cpu/0/msr This patch replaces the hard-coded use of cpu0 in turbostat with the current cpu, allowing it to run without a cpu0. Fewer cross-calls may also be needed due to use of current cpu, though this hard-coding was used only for the --debug preamble. Signed-off-by: Prarit Bhargava Signed-off-by: Len Brown

tools/power turbostat: correctly decode of ENERGY_PERFORMANCE_BIAS

2015-05-27T22:04:00Z

When EPB is 0xF, turbosat was incorrectly describing it as "custom" instead of calling it "powersave": < cpu0: MSR_IA32_ENERGY_PERF_BIAS: 0x0000000f (custom) > cpu0: MSR_IA32_ENERGY_PERF_BIAS: 0x0000000f (powersave) Signed-off-by: Len Brown

tools/power turbostat: enable turbostat to support Knights Landing (KNL)

2015-05-27T22:03:57Z

Changes mainly to account for minor differences in Knights Landing(KNL): 1. KNL supports C1 and C6 core states. 2. KNL supports PC2, PC3 and PC6 package states. 3. KNL has a different encoding of the TURBO_RATIO_LIMIT MSR Signed-off-by: Dasaratharaman Chandramouli Signed-off-by: Len Brown

tools/power turbostat: correctly display more than 2 threads/core

2015-05-27T21:26:42Z

Without this update, turbostat displays only 2 threads per core. Some processors, such as Xeon Phi, have more. Signed-off-by: Dasaratharaman Chandramouli Signed-off-by: Len Brown

tools: bpf_jit_disasm: fix segfault on disabled debugging log output

2015-05-27T04:24:10Z

With recent debugging, I noticed that bpf_jit_disasm segfaults when there's no debugging output from the JIT compiler to the kernel log. Reason is that when regexec(3) doesn't match on anything, start/end offsets are not being filled out and contain some uninitialized garbage from stack. Thus, we need zero out offsets first.

2015-05-16T22:27:33Z

Pull thermal fixes from Zhang Rui: "Specifics: - fix an issue in intel_powerclamp driver that idle injection target is not accurately maintained on newer Intel CPUs. Package C8 to C10 states are introduced on these CPUs but they were not included in the package c-state residency calculation. From Jacob Pan. - fix a problem that package c-state idle injection was missing on Broadwell server, by adding its id to intel_powerclamp driver. From Jacob Pan. - a couple of small fixes and cleanups from Joe Perches, Mathias Krause, Dan Carpenter and Anand Moon" * 'for-rc' of git://git.kernel.org/pub/scm/linux/kernel/git/rzhang/linux: tools/thermal: tmon: fixed the 'make install' command thermal: rockchip: fix an error code thermal/powerclamp: fix missing newer package c-states thermal/intel_powerclamp: add id for broadwell server thermal/intel_powerclamp: add __init / __exit annotations thermal: Use bool function return values of true/false not 1/0
