Hi,
When booting OpenBSD on a Lenovo B470e laptop (dmesg below), the
screen becomes garbled once the boot prompt disappears and the kernel
starts. The system remains responsive, however.
For context, this is the output of the `machine gop` command:
----
Mode 0: 1024 x 768 (stride = 1024)
Mode 1: 640 x 480 (stride = 640)
Mode 2: 800 x 600 (stride = 800)
Current Mode = 0
----
If I start from a fresh boot and...:
- Set the mode to 1: The screen flickers quickly and the resolution
changes appropriately. No display issues when booting the kernel
afterwards.
- Set the mode to 2: No visible changes (flicker/resolution change).
No display issues afterwards as well. This indicates that the machine
is actually in mode 2 but it's reporting that it's in mode 0.
- Set the mode to 0: No visible changes. Display issues remain.
- Set the mode to 1 or 2 and back to 0: The resolution actually
changes to 1024x768. No display issues afterwards.
If I remove the text mode setting code in efi_video_init() and boot...
- From the Boot Menu (F12): Machine reports that it's in mode 1 but
it's actually in mode 0. Display issues persist.
- Directly: Machine starts with mode 0 properly. No issues.
I've thought about calculating the framebuffer size (height * stride *
4) and comparing that with the one reported by the firmware to see if
there's an inconsistency (and switch the mode accordingly), but the
FrameBufferSize reported by the firmware seems to be a fixed, large
value. Not feasible.
While poking around with the dh command in the UEFI shell, I
discovered that there are two GOP instances in the system. The first
one (which LocateProtocol() locates) is virtual, and the other is
"physical" (as indicated by the presence of a device path in its
handle). The physical one, according to my tests, gives correct
information all the time. Here are their handles:

>From what I've read, it seems that the virtual instance is set up by
ConSplitter and it's known to be buggy in certain implementations.
Linux (EFISTUB) and recently, FreeBSD, both use the non-standard
"ConOut Protocol" to determine if a GOP instance is physical or not.
They use the first physical one available. Both run fine with no
issues on my laptop.

In addition to Linux and FreeBSD, here's how the other major EFI-aware
projects fare when run on my laptop:
- GRUB 2 (commit a4666d31babc3fd06e52f7bb9b4c871e685da9b9) works fine
when run directly but the screen remains blank if run through the Boot
Menu (graphical issue, remains responsive to commands like 'halt').
grub.cfg:
----
insmod efi_gop
loadfont "unicode"
insmod gfxterm
terminal_output gfxterm
----
- iPXE (commit 70995397e5bdfd3431e12971aa40630c7014785f with
CONSOLE_FRAMEBUFFER): Display is fine when run directly, garbled when
run through the Boot Menu.
- NetBSD 9.2: Likewise.
- rEFInd (commit 0d46f46ed7a2d453c9320469f211c5348120a1cd): Display is
fine when run directly, but when run through the Boot Menu, the screen
remains mostly blank with two icons and a small square thrown around.
Not sure what's going on here to be honest.
I'd like to emphasize that this issue is not unique to my specific
laptop model. Many users have experienced similar issues across
different OSes on different models/OEMs.
Some examples:
https://old.reddit.com/r/slackware/comments/i88d57/screen_garbled_need_to_change_eufi_gop_mode/
https://old.reddit.com/r/freebsd/comments/77ajtm/garbled_text_for_bsd_installer_on_lenovo_laptop/
(Likewise)
https://old.reddit.com/r/openbsd/comments/cidx7g/weird_output_on_booting_from_install_media_usb/
https://redmine.pfsense.org/issues/8253
etc...
The below diff adopts a similar approach to Linux/FreeBSD, but uses
the standard device path protocol instead. This is not a novel
approach. Insyde's CTO, Tim Lewis, used it in his UEFI maze game:
https://uefi.blogspot.com/2017/02/the-uefi-maze-game-part-4.html
I've also made the system panic in case no GOP instances are found.
One thing I'm not sure about is what would happen to the boot console
in a scenario where you have a virtual GOP and the output is being
redirected to multiple physical ones and the user does a modeset
(which would affect the first physical GOP that we selected earlier).
Further testing and investigation is very welcome.
Thanks.
