The following patch improves ISA IDE discovery. On a modern system those devices will probably be the same as under pci-ide tree of devices.
* Discover up to 4 IDE devices * Fix "Unimplemented package interface procedure" message during "Probe IDE"
Before patch:
show-devs
/pci/isa@1/ide-controller@i1f0/ide@1 /pci/isa@1/ide-controller@i1f0/ide@0 /pci/isa@1/ide-controller@i1f0/ide@0/<Unnamed>@0
ok select /pci/isa@1/ide-controller@i1f0/ide@0/<Unnamed>@0 Invalid ihandle
After patch:
/pci/isa@1/ide-controller@i1f0/ide@1 /pci/isa@1/ide-controller@i1f0/ide@0 /pci/isa@1/ide-controller@i1f0/ide@1/cdrom@2 /pci/isa@1/ide-controller@i1f0/ide@0/disk@1 /pci/isa@1/ide-controller@i1f0/ide@0/disk@0
Open issues:
ok select /pci/isa@1/ide-controller@i1f0/ide@1/cdrom@2 IDE data error: 0 Can't open deblocker package ok
It does not matter whether Qemu's CDROM device is attached or not. (For /pci/pci-ide@1,1/ide@1/cdrom@0 works when attached).
What is file /dev/ide/node.fc binary?
