MultiArchUefiPkg - x64/AArch64 compatibility for 64-bit RISC-V UEFI

x64/AArch64 UEFI drivers and apps on RISCV64 UEFI. Here’s the legend of the demo, which is an HDMI video capture of an AMD ATI Radeon HD 7750 adapter. 00:00 – UEFI boot screen. In the top left corner we see this is a RISC-V system. 00:20 – In UEFI shell running the ‘drivers’ command. At the bottom of the output we see “AMD GOP X64 Release Driver Rev.1.67” – this is the 64-bit x86 OpRom driver (GOP == Graphics Output Protocol). The emulation driver is what allows this non-native OpRom image to run on the RISC-V system. 00:27 – Boot an x64 UEFI application – in this case, an x64 build of the Shell. This demonstrates that not only drivers, but well-behaved applications can be supported as well (well behaved == not acting as an OS loader, not trying to mess with privileged state like interrupts/page tables and the like) 00:38 – Boot an AArch64 UEFI application – in this case, a Gameboy Color emulator running an open-source demo ROM that draws a “matrix-like” display. This shows that 64-bit Arm drivers and applications can be supported on RISC-V as well. 1:27 – Boot into Ubuntu. We see the video adapter has been picked up by the OS EFI framebuffer driver. The emulation driver brings the existing IHV ecosystem to standards-based RISC-V platforms. 1:44 – The video adapter has been reinitialized by the OS away from EFI framebuffer by a native Radeon DRM driver 3:40 – We’re in X11, and using ‘neofetch’ we can see what this system is – a Qemu-emulated platform with a pass-thru PCIe graphics adapter
