--- Comment #6 from Ed Maste <emaste@freebsd.org> ---
Ah, just found this proposed Linux change:
https://patchwork.kernel.org/project/linux-fbdev/patch/BLU437-SMTP246338AFF=
A84224C9B222DC32B0@phx.gbl/
"Hisilicon graphic driver: add fbdev support to hisilicon hi1710 graphic ch=
ip"

As far as I can tell it was not merged into Linux though. It would be great=
 if
someone can test a Linux distro on this hardware with a fbdev console.

The existence of this patch suggests to me that the hi1710 is in fact not f=
ully
VGA compatible. The most likely path forward here is to add a quirks table =
for
broken hardware, and default to hw.vga.textmode=3D1 here.

It is also possible that Huawei could provide that proposed driver under a
copyfree license and then someone could add it as a FreeBSD framebuffer dev=
ice.
