Hi Finn,
are there any substantial changes from what I'd tested before?
The request_region() stuff is new, and I reworked the host->get_lock and
host->release_lock changes. So you may want to review it again.
Done that - the weirdness around request_irq() that I remembered is not
actually an issue, that's taken care of by setting host->get_lock. And
your patch doesn't change anything for Falcon.
Tested on my Falcon - I can still use both IDE and SCSI (no stress test
done but I doubt it would turn out much different).
Not setting host->get_lock on Q40 will correctly request the IRQ for IDE
there, the same lowlevel IO routines can be shared by both, and there
wasn't ever much more that these old drivers did.
Please add my Reviewed-by as well as Tested-by.
Cheers,
Michael
Your patch conflicts with (I think) the Mac IDE patches now in Geert's
tree, and I'd rather avoid hand-patching the lot if at all possible:
m68k_q40_Replace_q40ide_with_pata_falcon_and_falconide
Applying: m68k/q40: Replace q40ide with pata_falcon and falconide

I should have sent these as a two-part series. Sorry about that.
You'll need to apply this patch first:

What's your baseline for this patch?
I've used v5.12 and v5.13-rc5, but mostly I develop on the mac68k branch
in my github repository.
(In the alternative: just add my Tested-by if nothing changed aside from the
IO region reservation)
I have tested these patches in Aranym (including a multi-platform
atari/q40 build which required your ISA fix) but I don't have any way to
test the q40-only code.
