Hi,
The patches that I sent were merged into that release (2.6.29). So X11
works again, and mac_esp supports both SCSI busses on the quadras 9x0.
very cool, I extra checked and I still had the option to disable the
scsi BUS in penguin.
Indeed I see:
[42949375.000000] mac_esp: using PDMA for controller 0
[42949378.080000] mac_esp: using PDMA for controller 1
My external MO disk doesn't get recognized though. I'll check that it
still works on MacOS though.
X11 doesn't work for me, but I'll write separately about that.
I haven't heard anything more since you raised it on this mailing list
back in October. I never implemented the workaround that was discussed
at
the time because I have more pressing bugs on my todo list, and because
I'd like to try and figure out how the hardware works before resorting
to
workarounds...
Oh sure, also because once a workaround gets implemented, the
motivation to do the real thing gets even less. The real access would
be very good together with EMILE.
and that hard disk performance is still bad.
If dmesg says that PDMA is in use on scsi0 and scsi1, then I'm afraid
it
probably isn't going to get any faster. But performance should be
comparable with NetBSD if not MacOS (though I never benchmarked
either).
I just run bonnie:

char operations are very slow (cpu bound? some libraries are
inefficient?) , but thi could have other reasons. I see that block
write is 1323 K/s and bloc reaad is 1.6, that is slower than the mac,
but not abysmal, I don't remember this exact configuration, but 2-3 M/s
were average for those old macs. IIRC the Q950 was a bit faster than
the others on the internal chain, but it is clear there that the driver
performs reasonably now.
