This series adds a simple implementation of legacy/native mode switching for PCI IDE controllers and updates the via-ide device to use it. The approach I take here is to add a new pci_ide_update_mode() function which handles management of the PCI BARs and legacy IDE ioports for each mode to avoid exposing details of the internal logic to individual PCI IDE controllers. As noted in [1] this is extracted from a local WIP branch I have which contains further work in this area. However for the moment I've kept it simple (and restricted it to the via-ide device) which is good enough for Zoltan's PPC images whilst paving the way for future improvements after 8.2.

I'll make the change to the switch() statement and then post an updated v2 later this evening. >> [1] https://lists.gnu.org/archive/html/qemu-devel/2023-10/msg05403.html >> >> Mark Cave-Ayland (2): >> ide/pci.c: introduce pci_ide_update_mode() function >> hw/ide/via: implement legacy/native mode switching >> >> hw/ide/pci.c | 90 ++++++++++++++++++++++++++++++++++++++++++++ >> hw/ide/via.c | 20 +++++++++- >> include/hw/ide/pci.h | 1 + >> 3 files changed, 109 insertions(+), 2 deletions(-) ATB, Mark.

I've verified that AmigaOS and MorphOS and Linux still boot on pegasos2 and it also works with AmigaOS on amigaone so I'm OK with this. I only had some small comments in patch 2. This can replace patch 1 in my series, the other patches should just apply on top of this too but I can resubmit based on this when it becomes final.
