Hi Tianyun,
I was having this same trouble a few weeks ago, and I should be freed up
to try and debug it in the next few days. From what I could find, this
appears to be a bug in the IDE controller. First, since IDE controllers
only allowed for 2 channels, that limits the simulated system to 2 master
and 2 slave disks. However, it looks like the IDE controller device
doesn't correctly recognize master vs. slave drives (I am running x86 also,
which might be part of the problem), so this limits the system to 2 master
disks concurrently in the simulated system.
While I'm taking a look, if the benchmarks you are running do not require
an excessive about of simulated memory, I'd recommend that you remove the
swap disk from the south bridge disks array like so:
disk0 = CowIdeDisk(driveID='master')
disk2 = CowIdeDisk(driveID='master')
disk4 = CowIdeDisk(driveID='master')
disk0.childImage(mdesc.disk())
disk2.childImage(disk('linux-bigswap2.img'))
disk4.childImage(disk('test.img'))
* self.pc.south_bridge.ide.disks = [disk0, disk4]*
Will keep you posted. Hope this helps,
Joel
