freebsd stable - Nov 2018 - Fujitsu Lifebook E751 (iGPU: HM65): distorted console with UEFI boot

-----BEGIN PGP SIGNED MESSAGE-----
Hash: SHA512

I ran into some trouble booting off a Fujitsu Lifebook E751 (firmware is latest,
r1.22
from 2013). The E751 is of model series S26391-K326-V100 and equipted with a
Core
i5-2520M CPU and supposed to be also equipted with a iGPU HM65 according to the
techniscal specifications from Fujitsu.

Trying to boot off 12-PRERELEASE/12-RC2 and/or 13-CURRENT (most recent I could
grap from
the download page), the screen becomes distorted immediately after the kernel
has
loaded and initialised/booted. The screen is at the loader's all right so
far.

Trying to disable graphics mode via escaping to the loader's prompt and
setting

set hw.vga.textmode=1

subsequently loading the kernel and then booting, doesn't help. The screen
is distorted
again. The notebook seems UEFI only and doesn't boot off from MBR partioned
devices (i.e.
NanoBSD I used to use).

Loading /boot/kernel/i915kms.ko

after manually having loaded /boot/kernel/kernel (and not booted yet)
doesn't change
anything either.

Booting off and installing Linux (Ubuntu, Mint so far, most revent verions I can
get my
hands on) is no problem. The console works fine from the beginning and so the
graphics.

Is there a chance to get a FreeBSD booting the easy way? 

The provided boot images do not contain any of the
graphics/drm-stable|next|legacy-kmod
stuff, I tried to load i915kms.ko off from /boot/modules/ (were those modules
from the
ports are supposed to reside) but no chance.

Before starting investigating this issue further I'd like to ask wether
there is a
general support provided or is that type of notebook dead matter for FreeBSD of
the
modern kind?

Thanks in advance,

oh

Note about hw.vga.textmode: this tunable has no meaning for UEFI - first of all,
there is no API to change to VGA text mode in UEFI, secondly, there may or may
not be VGA (firmware) at all. We only do land in kernel with linear framebuffer
mode active and all we have is information about that mode (FB address, size and
color bits). In *worst* case, it is actually even possible that we only have
UEFI API for boot loader and no linear framebuffer for kernel.

distorted console after kernel start means that either the kernel efifb driver
does something wrong, or the console device gfx mode change did happen but the
FB driver was not properly informed about the fact.

 Could you post a picture somewhere ?

 I have a laptop which have efifb problem, what I need to do is (at
loader prompt) :

 gop set 4 (to switch to a different mode)
 gop set 0 (switch to the correct mode)

 You can gop list (iirc) to checks the available mode.

 The problem is that we are mixing serial and gop in loader.efi and
when you set one mode in serial (or for SIMPLE_TEXT_PROTOCOL) is can
mess the graphical mode.

AFAICT, BIOS style boot should be possible with the named laptop. Is CSM
enabled within the Firmware?
