Subject: [PATCH 5.3-6.19 0/1] Avoid oops on illegal VGA register access
Date: Sat, 7 Mar 2026 00:23:46 +0900 [thread overview]
Message-ID: <20260306152413.758919-1-Simon.Richter@hogyros.de> (raw)
Hi,
this is a backport of https://patchwork.freedesktop.org/series/161721/ that
should apply to anything between 5.3-rc4 and 6.19.
It adds a way to avoid the illegal VGA accesses on non-x86 platforms by
letting these platforms report that VGA registers cannot be mapped.
This patch alone doesn't fully solve the problem, it also needs complementary
changes in vgaarb to actually report this, but since the interface is unchanged
and it is wrong to ignore the error code anyway, little coordination is needed
here.
Simon
