TB flags are defined by cpu_get_tb_cpu_state(), you can find the x86
version in target-i386/cpu.h.

We do, but they're hacked into the scsi layer, see hw/sun4m_iommu.c. I
don't know if it's a standalone iommu on real hardware or whether it is
part of the HBA.

This error may be a PPC specific problem, but I don't have another
environment where I can test it (i386 doesn't seem to use pwrite64),
so I ask for a bit of help/check.
I am in a 32bit linux testing the qemu-ppc.
My test program:

Where can I find the list of IO devices virtualized for QEMU ?

Without this patch, the -hdachs argument had to occur either
BEFORE the corresponding "-hda" option, or AFTER the plain
disk image name (if neither -hda nor -drive is used). Otherwise
it would effectively be ignored.
Option -hdachs still has no effect on -drive, but that seems best.

This patch adds some optional compatibility hacks (default
disabled) to allow Microport UNIX to function under qemu.
I've tried to structure it to be easy to add more hacks for other
old CGA programs, if anyone ever needs them.
Microport UNIX System V/386 v 2.1 (ca 1987) tries to program
the CGA
These are normally ifdefed out and don't matter. But if you enable
them, they ought to be correct.

Intel's definition of "edge triggered" means: "asserted with a
low-to-high transition at the time an interrupt is registered and
then kept high until the interrupt is served via one of the
EOI mechanisms or goes away unhandled."
So the only difference between edge triggered and level triggered
is
* Fix high-vs-low counting logic to match the timing diagrams
and descriptions in Intel's documentation (23124406.pdf).
* Improve reading back the count in mode 3.
* Handle GATE input properly with respect to the OUT line, and add
a FIXME comment for reading back the counter. GA
No change in functionality.
Clarify that the only difference between level triggered and
edge triggered interrupts is on the leading edge.

Changes since previous version:
* Patches 1, 2, 3, and 4, and 7 haven't changed at all.
* The only change to patch 6 is I added test cases output to the
commit message.
* Patches 5 and 8 are new. Patch 8 has downsides; see

It is not at all clear that this is the best way to handle this.
See the detailed notes in the cover letter of this patch series.
UPDATE: Also, some fixes moved the leading edge by 1 CLK

No, just ignored its result for an RFC.
