Is there any way to obtain detailed information from the DART IOMMU if
a PCI busmaster device initates a DMA to or from an address which was
never entered into the DART? Is the bad address logged someplace? I
thinking that since the DART is so smart, this should be possible...
Right now, the behaviour (on my 10.3.5 G5 test box) seems the same as
x86 linux. Eg, the busmaster DMA bit is cleared and you cannot
re-enable the busmaster DMA bit until reboot (or until you've cleared the
master abort in the status register).
Thanks,
Drew
