I think so. I think there are definitely some robustifications needed, but generally it'd be good to know if I need any major overhauls. Also, at this point in the series, it's entirely opt-in, and any regressions should be fixable.

bwidawsk added a comment to D18006: Align IA32_ARCH_CAP MSR definitions and use with SDM rev. 068..

Talked with Kostik offline. Patch should say bit 3 instead of 4 for VM entry. Patch itself is correct.

Nov 16 2018, 8:13 PM
bwidawsk accepted D18006: Align IA32_ARCH_CAP MSR definitions and use with SDM rev. 068..

Can you please identify where the docs say

Nov 16 2018, 7:54 PM
bwidawsk added a comment to D18006: Align IA32_ARCH_CAP MSR definitions and use with SDM rev. 068..

I asked for clarification and hopefully, I will have some by the end of the day. My understanding is that RDCL_NO still determines whether or not you need to mitigate L1TF type vulnerabilities.
