Problem on arm is that you can't expose something as pci memory to the guest which in reality isn't pci memory but normal ram (like the emulated vga memory pci bar). Storing a framebuffer in normal ram is (as far I know) no problem. But updates are a problem then, you have to: (a) notify the host about updates (which is what virtio-gpu does), or (b) turn on dirty tracking for *all* guest ram so you can detect display updates automatically (lot of overhead, vga needs dirty tracking only for the 16M pci bar), or (c) update whole framebuffer unconditionally in regular intervals (doesn't look great too). cheers, Gerd _______________________________________________ edk2-devel mailing list edk2-devel@lists.01.org https://lists.01.org/mailman/listinfo/edk2-devel
