Subject: [edk2-devel] [PATCH v2 0/2] Support CloudHv guests with >1TB of RAM.
Date: Thu, 11 Jan 2024 19:02:13 +0000	[thread overview]
Message-ID: <cover.1704998169.git.tbarrett@crusoeenergy.com> (raw)

[-- Attachment #1: Type: text/plain, Size: 2351 bytes --]

This series adds support for cloud-hypervisor guests with >1TiB
of RAM to Ovmf. This bug was solved for Qemu back in 2017
https://bugzilla.redhat.com/show_bug.cgi?id=1468526. The bug is
still occuring for CloudHv guests because the PlatformScanE820
utility is not currently supported for CloudHv. 

My working branch for these changes can be found here:
https://github.com/thomasbarrett/edk2/tree/cloud-hv-1tb-ram
