Public bug reported:
While qemu's scalar emulation tends to be excellent, qemu's SIMD
emulation tends to be incorrect (except for arm64 from x86_64)--i have
found this both for mipsel and arm32. Until these code paths are
audited, which is probably a large job, it would be nice if qemu knew
its em
Here is a pull request for the zig language that runs into this problems
in qemu https://github.com/ziglang/zig/pull/2945/
I have more code for validation if someone is working on this.

Linux kernel 5.4 will introduce a new memory map for SWIM device.
(aee6bff1c325 ("m68k: mac: Revisit floppy disc controller base addresses"))
Until this release all MMIO are mapped between 0x50f0 and 0x50f4,
but it appears that for real hardware 0x50f0 is not the base address:
the MMIO

I asked Richard about this and he said this is OK because this is

Move it from the stack.
It's only 24 bytes, and this simplifies the dp8393x_get()/
dp8393x_put() interface.

The card is not able to exit from exhaustion state, because
while the drive consumes the buffers, the RRP is incremented
(when the driver clears the ISR RBE bit), so it stays equal
to RWP, and while RRP == RWP, the card thinks it is always
in exhaustion state. So the driver consumes all the buffers
This series starts with a cleanup of the DMA buffer, moving
it from the stack to the state structure.
The following patch allows to negociate the IP address with
the DHCP server.
The last one fixes the buffer exhaustion case.
With this series Q800 networking card is fully functionnal.

With the Quadra 800 emulation, mos6522 timers processing can consume
until 70% of the host CPU time with an idle guest (I guess the problem
should also happen with PowerMac emulation).
On a recent system, it can be painless (except if you look at top), but
on an old host like a PowerMac G5 the gue
