Subject: [PATCH 0/2] cdrom: gdrom: fix block I/O and capacity setting
Date: Sun, 5 Apr 2026 10:23:28 +0200 [thread overview]
Message-ID: <20260405082330.4104672-1-fuchsfl@gmail.com> (raw)
Hi all,
This series fixes a gdrom driver Oops due to bad MMIO register access and
fixes the missing updates of the block layer gendisk capacity that
prevented ISO9660 mounts from working.
The change was tested on real Sega Dreamcast devices (PAL-E, NTSC-J)
with physical CD-R discs and with GDEMU emulated discs. Before: Oops on
mount and an unusable drive. After: Successfully able to mount and use
the inserted medium.
Thanks,
Florian
