The attached patch causes both boot1 and loader.efi to switch to text mode. This only seems to make a difference on Macs where otherwise no information was being displayed.
The ConsoleControl.h file is copied from EdkCompatibilityPkg/Foundation/Protocol/ConsoleControl in https://github.com/tianocore/edk2. I tested that both programs are able to change to text mode by enabling only one of them at a time. With this patch I am able to see loaders output on all the macs I tried. The kernel boots correctly on a MacPro, but unfortunately it doesn't seem to be able to find the efi buffer in a MacBookPro. Some design questions: * Why do we have both boot1 and loader? It is just the issue with building a usb image without root that requires having a boot1 that has a predictable size? * Even if we want to keep both boot1 and loader, could boot1 use libefi? * Is it ok to always switch to text mode in libefi or should it provide a switch_to_text_mode function? Cheers, Rafael
