It works great. Some observations:

- When the kernel starts booting, it prints lines painfully slow on
  my Asus laptop. When the kernel initialises genfb(4), printing
  suddenly speeds up. If I connect to Sony TV via HDMI, it somewhat
  slow but acceptable.
- I can't figure out how to change screen size in boot.cfg. Adding
  text=2 to boot.cfg doesn't work.
- Likewise, I don't know how to change screen size in genfb(4). I will
  google more on the topic.
- Does the bootloader suport msdos fs? Currently, I create an ffs
  partition solely for hosting boot.cfg file. It would be nice to
  read boot.cfg file from the boot EFI partition.

Hi Kimihiro,

That's cool! I can boot from your bootloader. The compilation fails,
though:

/home/alnsn/netbsd-current/tooldir.amd64/bin/x86_64--netbsd-ld: cannot
find startprog32.o: No such file or directory

I'm building on amd64 -current.

EFI native support on amd64

2016-12-08 Thread Alexander Nasonov 
Hi,

I see some pieces of EFI in the base (gnu-efi, grub support) but
no complete native support. If I remember correctly, someone worked
on it but I don't have any link to their work. Are there any patches
I can hack on further?

PS I was able to link a hello world amd64 executable. It printed
gibberish, though, presumably because it expected CHAR16. Otherwise,
coding was quite easy given my lack of knowledge in this area.
