Enhanced MSR Coverage for Intel CPU Models via New Allowlists #141
Conversation
…added additional allowlists to extend support to more processor families

Yes, please. This went through far more iterations than I had intended, but we've ended up with something that's far more useful than what we've had before.
To give a concrete example of just how useful this is: I wanted to be able to monitor temperature and knew there was an MSR for it, so I cracked open volume 3B and started grepping. I found MSR_THERM_STATUS. Does it exist on this MSR? If so, is it core or package scope?
Opening up the new allowlist confirmed its existence as well as giving me the MSR address and table. That allowed me to track down the core/package info more or less immediately. As an added bonus, I saw the IA32_PACKAGE_THERM_STATUS MSR in the allowlist, which I wouldn't have noticed otherwise.
This PR is a terrific improvement to our workflow. I'll be using this branch until it goes into mainline.
New Allowlists Introduced for Intel CPU Families/Models:
06_2A, 06_2D, 06_3A, 06_3C, 06_3D, 06_3E, 06_3F, 06_45, 06_46, 06_47, 06_4E, 06_4F, 06_55, 06_56, 06_5E, 06_66, 06_6A, 06_6C, 06_7D, 06_7E, 06_8C, 06_8D, 06_8E, 06_8F, 06_97, 06_9A, 06_9E, 06_A5, 06_A6, 06_BFFull Coverage:
These allowlists encompass all the applicable MSRs for the mentioned CPU models as detailed in the Intel 64 and IA-32 Architectures Software Development Manual (Volume 4, 335592-079US, March 2023).
Objective:
Facilitate the creation and customization of allowlists through expanded templates, ensuring comprehensive coverage and enhanced safety.
Core Functionality:
Unchanged.
