On 1.21.x, I'm afraid there are two known issue for ancient Tier-II ports.


(1) out of bounds problem in xserver/hw/xfree86/modes/xf86Crtc.h

OpenBSD/luna88k maintainer (Kenji Aoyama) reported the following fix
was neceesary for non-XFree86 driver based dumb server (on luna88k etc.):

 https://cvsweb.openbsd.org/cgi-bin/cvsweb/xenocara/xserver/hw/xfree86/modes/xf86Crtc.h#rev1.16


(2) "-flipPixels" option removal

"-flipPixels" option (that inverts black and white on 1bpp server)
has been removed since 1.21.
 https://gitlab.freedesktop.org/xorg/xserver/-/commit/d1c00c859c6676fbb540420c9055788bc19cb18f

As noted in the log the upstream authors claim
"No supported driver supports 1bpp anymore, nor has in a very long time."

Howeverwe we still have several working servers (xf86-video-wsfb based
servers on mac68k and luna68k, monolithic servers for sun3 and x68)
and at least there was a report that this option was mandatory on SE/30.
So I would like to revert this change.


I've filed several issue reports about the 1bpp server including this,
but it looks the upstream has ~no interest to keep it.

Thanks,
