Hi!
Daniel Jacobowitz a écrit :
These patches for qemu let IDE and initrd work in the defconfig.
It seems to function - I was able to get as far as partitioning
the drive in the debian installer and the next time I started qemu
the new partitions were found. But the installer hangs up trying
to format swap.
Of course, what would be really nice would be a PCI controller.
I'm not brave enough to try.
I'm not going to submit the qemu change until I have some better
evidence that it all works right (or someone else does).
First of all, thanks a lot for your work, that makes QEMU mips more usable.
The IDE part works very well, though there seems to be some problems
with userland tools (mke2fs), an instruction is probably not/bad
emulated. I now have a system with the root on the IDE drive and with swap.
The initrd seems to works well, but it generates a strange failure
during the boot:
[...]
Mount-cache hash table entries: 512
Checking for 'wait' instruction... available.
checking if image is initramfs...it isn't (bad gzip magic numbers);
looks like an initrd
Bad page state in process 'swapper'
page:81010000 flags:0x00080000 mapping:00000000 mapcount:0 count:0
Trying to fix it up, but a reboot is needed

This message is not present when initrd is not used, and it also does
not appear with the previous way of passing the size and location of the
initrd.
I don't have time to look more now, I will give you some more details
when/if I found some time to work on that.
Bye,
Aurelien
