[Qemu-devel] [Bug 1276879] Re: lots of dma command 10, 14 not supported

[tyler knosis]

So, Zoltan pointed to two patches.  I applied the first 
(v8-06-10-i8259-fix.....),
but the second patches a file that is not in version 1.7.0.

With the one patch, I am now able to get past the step where it crapped out
before.  The dma messages are still there, but it seems that they can be 
ignored.
NextStep can now install its basic system onto a file.

Thank you for the help so far.

Now, I get to the point when NeXTStep want me to click on something to configure
the new system, but QEMU is not grabbing the mouse.  After this step, it will 
install
the remainder of the system + apps.

I have a USB mouse on a x86_64 linux machine, and QEMU 1.7.0.  This is the
command line I used:
qemu-system-x86_64 -hda x.img -fda f.img -cdrom cd.img

I have tried ctl-alt (both sides of the keyboard) to no avail.

Title:
  lots of dma command 10, 14 not supported

Status in QEMU:
  New

Bug description:
  Trying to install NeXTSTEP 3.3 onto a 2GB file with QEMU 1.7.0.
  In the terminal that started QEMU, there are a lot of
      dma: command 10 not supported
  and 
      dma: command 14 not supported
  messages.  When the installation of NeXTSTEP gets to
  'preparing disk for nextstep installation', there are a lot
  of messages that ATA command c5 failed and other info.
  The result is a failed installation.

  Is this a bug in QEMU?  Is there a workaround, e.g. by
  disabling DMA altogether?

  thank you
