Re: [edk2-devel] Running OVMF on crosvm

Hi Mike, What's the point of upstreaming firmware for crosvm? Isn't crosvm supposed to be a "thin" hypervisor that runs the kernel directly? Thanks, Pedro On Fri, Jun 17, 2022 at 12:40 AM Mike Gerow via groups.io wrote: > Hi Folks, > > For the last few months I've been using OVMF with crosvm

Thanks for the great answer. After some discussion in the zulip [1], I have some approaches that I will try first. As for calling C, EFIABI from Rust, yes, it is quite well supported. Rust also has a specific EFIABI now, since some EFI platforms don't use C calling conventions. As for the entry

A couple things to get a clean log 1. Try removing your Build dir so we know it is a clean build 2. Use -n 1 option to disable mp build so the log is easier to follow 3. Use -j logfile.txt option to generate a complete log file Mike From: devel@edk2.groups.io On Behalf Of M.T. Sent:

Min, I prefer not to do this since there is already 28 patches. The line changes are mostly from the .h and .c files, I do not think there is much benefit from moving the the .inf files to a different patch.  Doing something like that will still leave 5800 lines changes in this patch. Judah
