As a follow-up to my previous post, after rereading [1], I tried to compare the
status of radeondrm, efifb and amdgpu in 7.4 /bsd boot and 7.5 /bsd.upgrade
boot. I got this (manually retyped to avoid large attachments):
1. The result of entering `boot -c` at the `boot>` prompt with /bsd.upgrade not
having the execute bit (so 7.4 /bsd would boot by default):
OpenBSD 7.4 (GENERIC.MP) #1397: Tue Oct 10 09:02:37 MDT 2023
dera...@amd64.openbsd.org:/usr/src/sys/arch/amd64/compile/GENERIC.MP
real mem = 6277246976 (5986MB)
avail mem = 6067273728 (5786MB)
User Kernel Config

2. The result of entering `boot -c` at the `boot>` prompt with /bsd.upgrade
having the execute bit set (so 7.5 /bsd.upgrade would boot by default):
OpenBSD 7.5 (RAMDISK_CD) #76: Wed Mar 20 15:53:54 MDT 2024
dera...@amd64.openbsd.org:/usr/src/sys/arch/amd64/compile/RAMDISK_CD
real mem = 6277246976 (5986MB)
avail mem = 6082772992 (5800MB)
User Kernel Config

UKC> find efifb
41 efifb0 at mainbus0 apid -1 flags 0x0

So it seems that 7.5 /bsd.upgrade doesn't detect nor configure the radeondrm
and amdgpu devices?
