Linux kernel development work - see feature branches https://git.zx2c4.com/linux-dev/atom/arch/x86/include/asm/shared/msr.h?h=linus%2Fmaster 2022-04-06T10:59:17Z 2022-04-06T10:59:17Z Michael Roth michael.roth@amd.com 2022-02-09T18:09:59Z urn:sha1:176db622573f028f85221873ea4577e096785315 The current set of helpers used throughout the run-time kernel have dependencies on code/facilities outside of the boot kernel, so there are a number of call-sites throughout the boot kernel where inline assembly is used instead. More will be added with subsequent patches that add support for SEV-SNP, so take the opportunity to provide a basic set of helpers that can be used by the boot kernel to reduce reliance on inline assembly. Use boot_* prefix so that it's clear these are helpers specific to the boot kernel to avoid any confusion with the various other MSR read/write helpers.
