I tried gop blt off on my old laptop and it worked there. Surprisingly, gop blt off case is significantly *slower* than gop blt on case.

In this case, I can see gop blt off is significantly faster.

faster than 'blt on' with the same resolution? It definitely is faster than 4K resolution.

Unfortunately, I do not see anything on screen if I do gop blt off. *Blindly* typing gop blt on makes it start printing characters again. Maybe pixel color is wrong, e.g., background color == foreground color?

use 'gop get' and see if it reports framebuffer address., or better yet, can you paste the output?

I updated the patch to revert rGe1ebda4458bb and re-apply my patch.

Gleb added a stopgap in rGe1ebda4458bb but I don't like it because we will have vfs.ffs node in MINIMAL kernel.

I found some time and tried it on Intel Core 8th gen laptop.

I agree that we should follow other implementations.

However, all fillers must occupy proper spaces, i.e., <HANGUL_CHOSEONG_FILLER> => 2, <HANGUL_JUNGSEONG_FILLER> => 0, and <HALFWIDTH_HANGUL_FILLER> => 1.

Ah, ok, thanks for confirming that- so if I just drop the ignorable check, the fillers return to their previous value with exception to <HANGUL_JUNGSEONG_FILLER> since it falls in the Hangul Kamo range that we're forcing to zero-width. That looks right based on what you've written, since omitted values default to 1.

FYI, the fix was incomplete. I fixed remaining ones in 7270b8992214.

I followed a different import process than what’s described in FreeBSD-UPGRADE because it was much simpler for me to use rsync -av —-delete to update the contents than multiple calls to find/tar/comm.
