I’m 99% sure this is the trouble, I don’’t really understand IRQ’s and interrupts, there
is some info in the Rage_128_register_referance_guide.
I tested my theory via OS X 10.4.11and it mapped the VRAM rather than giving me the
ATY:Not Usable, it also changed the screen resolution twice, once to 640x480 then to
1280x960.
dev /pci/@f
“ /pci/@f” select-dev
“ ATY,Rage128Pd” encode-string “ name” property
1 encode-int “ interrupts” property
boot
OS X would not be able to change the screen resolution if the ‘NDRV’ didn’t load!!!
So I’m 99% sure this is the trouble and we need to figure out how to create a mapped
interrupt for the card, rather than this dummy
Interrupt I create because I’m a dummy;-)

OS X would not be able to change the screen resolution if the ‘NDRV’ didn’t load!!!
So I’m 99% sure this is the trouble and we need to figure out how to create a mapped
interrupt for the card, rather than this dummy
Interrupt I create because I’m a dummy;-)

OK we might be onto something but still don't understand what exactly is
missing and just adding the property may be enough to get the NDRV load
but then probably will hang eventually if it relies on the device
generating interrupts which we don't emulate. I don't know either how IRQ
is used in Rage128P and haven't checked the docs but in general a device
can have an interrupt line that it can use to send interrupt request to
the CPU when it needs attention (such as finished with an async task, some
buffer is full or empty, etc.). These are likely settable in the device's
registers to tell it when to generate interrupt so we should implement
that functionality. But it's likely we don't even emulate the function
that should generate an interrupt yet as the emulation is very simple
currently so first that function needs to be implemented so we can
implement an interrupt.

MacOS does not like the above. With sufficiently large debug level it

then booting stops later due to the above error. So we need to make sure
these properties match with whatever they should match.
This interrupts property should be added by OpenBIOS if the card specifies
it uses an IRQ, this is done in drivers/pci.c::ob_pci_configure_irq() if I
understood that right. That looks at the config of the PCI device (see
https://wiki.osdev.org/PCI). We can patch ati-vga in QEMU to say it uses
an IRQ:
diff --git a/hw/display/ati.c b/hw/display/ati.c
index 84961d193f..d89153a826 100644
--- a/hw/display/ati.c

}
Then OpenBIOS adds the interrupts property and I don't get the above fatal

Then does not boot further from here so you can keep continue guessing why
it hangs (maybe waiting for an interrupt?) now or check what the NDRV
wants to do to understand better what we need. (I haven't tried OS X.)
