Hi Len,
Today's linux-next merge of the idle tree got a conflict in
arch/x86/include/uapi/asm/msr-index.h between commit 2f86dc4cddcb
("intel_pstate: Add support for HWP") from the pm tree and commit
a8b65b07d753 ("tools/power turbostat: decode MSR_*_PERF_LIMIT_REASONS")
from the idle tree.I fixed it up (see below) and can carry the fix as necessary (no action is required). -- Cheers, Stephen Rothwell s...@canb.auug.org.au diff --cc arch/x86/include/uapi/asm/msr-index.h index 62838e54947d,c1cb18be540e..000000000000 --- a/arch/x86/include/uapi/asm/msr-index.h +++ b/arch/x86/include/uapi/asm/msr-index.h @@@ -149,48 -149,10 +149,52 @@@ #define MSR_CORE_C1_RES 0x00000660 +#define MSR_CC6_DEMOTION_POLICY_CONFIG 0x00000668 +#define MSR_MC6_DEMOTION_POLICY_CONFIG 0x00000669 + +/* Hardware P state interface */ +#define MSR_PPERF 0x0000064e +#define MSR_PERF_LIMIT_REASONS 0x0000064f +#define MSR_PM_ENABLE 0x00000770 +#define MSR_HWP_CAPABILITIES 0x00000771 +#define MSR_HWP_REQUEST_PKG 0x00000772 +#define MSR_HWP_INTERRUPT 0x00000773 +#define MSR_HWP_REQUEST 0x00000774 +#define MSR_HWP_STATUS 0x00000777 + +/* CPUID.6.EAX */ +#define HWP_BASE_BIT (1<<7) +#define HWP_NOTIFICATIONS_BIT (1<<8) +#define HWP_ACTIVITY_WINDOW_BIT (1<<9) +#define HWP_ENERGY_PERF_PREFERENCE_BIT (1<<10) +#define HWP_PACKAGE_LEVEL_REQUEST_BIT (1<<11) + +/* IA32_HWP_CAPABILITIES */ +#define HWP_HIGHEST_PERF(x) (x & 0xff) +#define HWP_GUARANTEED_PERF(x) ((x & (0xff << 8)) >>8) +#define HWP_MOSTEFFICIENT_PERF(x) ((x & (0xff << 16)) >>16) +#define HWP_LOWEST_PERF(x) ((x & (0xff << 24)) >>24) + +/* IA32_HWP_REQUEST */ +#define HWP_MIN_PERF(x) (x & 0xff) +#define HWP_MAX_PERF(x) ((x & 0xff) << 8) +#define HWP_DESIRED_PERF(x) ((x & 0xff) << 16) +#define HWP_ENERGY_PERF_PREFERENCE(x) ((x & 0xff) << 24) +#define HWP_ACTIVITY_WINDOW(x) ((x & 0xff3) << 32) +#define HWP_PACKAGE_CONTROL(x) ((x & 0x1) << 42) + +/* IA32_HWP_STATUS */ +#define HWP_GUARANTEED_CHANGE(x) (x & 0x1) +#define HWP_EXCURSION_TO_MINIMUM(x) (x & 0x4) + +/* IA32_HWP_INTERRUPT */ +#define HWP_CHANGE_TO_GUARANTEED_INT(x) (x & 0x1) +#define HWP_EXCURSION_TO_MINIMUM_INT(x) (x & 0x2) + + #define MSR_CORE_PERF_LIMIT_REASONS 0x00000690 + #define MSR_GFX_PERF_LIMIT_REASONS 0x000006B0 + #define MSR_RING_PERF_LIMIT_REASONS 0x000006B1 + #define MSR_AMD64_MC0_MASK 0xc0010044 #define MSR_IA32_MCx_CTL(x) (MSR_IA32_MC0_CTL + 4*(x))
