This series adds functionality to print a dot graph of a PPTT table. This helps with understanding and debugging PPTT tables. The dot graph generator functionality is generic and could be used

From: Marc Moisson-Franckhauser <marc.moisson-franckhauser@...> Bugzilla: 3378 (https://bugzilla.tianocore.org/show_bug.cgi?id=3378) This generates a dot file from the PPTT table that can be

I've updated both the x86 and aarch64 code to add checks that the RDRAND and RNDR instructions are supported before trying to use them in GetRandomNumber[16,32,64,128]. However, it causes the X64

Noted. I guess Tom's patches were not accepted when I rebased the the SNP patches. Will pick those changes in next rev.

Thanks Laszlo, I will go through the feedback on this patch and address them in next rev. -Brijesh

Hi Dov, What you describe (= runtime guest OS access) seems to justify changing the memory type of this allocation. However, that update doesn't look tied to SEV-SNP -- it's basically a "change of

Actually, I've changed my mind, regarding the squashing. Patch#21 is already large, and the module-scope PciLib override requires a fair bit of justification (commit message, 5 DSC files modified

The above explanation is inexact. There are several typos ("APIC" is incorrect, "ACPI" would be correct, for the TimerLib instance in question), but that's really just a side observation. The precise
