x86/uapi: Do not export as part of the user API headers

2015-06-07T13:36:04+00:00

This header containing all MSRs and respective bit definitions got exported to userspace in conjunction with the big UAPI shuffle. But, it doesn't belong in the UAPI headers because userspace can do its own MSR defines and exporting them from the kernel blocks us from doing cleanups/renames in that header. Which is ridiculous - it is not kernel's job to export such a header and keep MSRs list and their names stable. Signed-off-by: Borislav Petkov Acked-by: H.

x86/asm/msr: Make wrmsrl_safe() a function

2015-06-05T07:41:22+00:00

The wrmsrl_safe macro performs invalid shifts if the value argument is 32 bits. This makes it unnecessarily awkward to write code that puts an unsigned long into an MSR. Convert it to a real inline function. For inspiration, see: 7c74d5b7b7b6 ("x86/asm/entry/64: Fix MSR_IA32_SYSENTER_CS MSR value"). Signed-off-by: Andy Lutomirski Cc: Cc: Andrew Morton Cc: H.

x86: Add another set of MSR accessor functions

2014-03-13T22:34:45+00:00

We very often need to set or clear a bit in an MSR as a result of doing some sort of a hardware configuration. Add generic versions of that repeated functionality in order to save us a bunch of duplicated code in the early CPU vendor detection/config code.

x86 / msr: add 64bit _on_cpu access functions

2013-10-16T22:36:06+00:00

Having 64-bit MSR access methods on given CPU can avoid shifting and simplify MSR content manipulation. We already have other combinations of rdmsrl_xxx and wrmsrl_xxx but missing the _on_cpu version. Signed-off-by: Srinivas Pandruvada Signed-off-by: Jacob Pan Reviewed-by: H.

x86, msr: Unify variable names

2013-04-02T23:03:32+00:00

Make sure all MSR-accessing primitives which split MSR values in two 32-bit parts have their variables called 'low' and 'high' for consistence with the rest of the code and for ease of staring.

Merge branch 'x86/cpu' into perf/core

2012-07-05T19:12:11+00:00

Merge this branch because we changed the wrmsr*_safe() API and there's a conflict. Signed-off-by: Ingo Molnar

x86, cpu: Rename checking_wrmsrl() to wrmsrl_safe()

2012-06-07T20:32:04+00:00

Rename checking_wrmsrl() to wrmsrl_safe(), to match the naming convention used by all the other MSR access functions/macros. Signed-off-by: H. Peter Anvin

x86, cpu, amd: Deprecate AMD-specific MSR variants

2012-06-07T18:43:30+00:00

Now that all users of {rd,wr}msr_amd_safe have been fixed, deprecate its use by making them private to amd.c and adding warnings when used on anything else beside K8.
