Subject: [PATCH 0/5] dp8393x: fixes for MacOS toolbox ROM
Date: Sun, 13 Jun 2021 17:37:33 +0100 [thread overview]
Message-ID: <20210613163738.2141-1-mark.cave-ayland@ilande.co.uk> (raw)
Here is the next set of patches from my attempts to boot MacOS under QEMU's
Q800 machine related to the Sonic network adapter.
Patches 1 and 2 sort out checkpatch and convert from DPRINTF macros to
trace-events.
Patch 3 fixes the PROM checksum and MAC address storage format as found by
stepping through the MacOS toolbox.
Patch 4 ensures that the CPU loads/stores are correctly converted to 16-bit
accesses for the network card and patch 5 fixes a bug when selecting the
index specified for CAM entries.
NOTE TO MIPS MAINTAINERS:
- The Sonic network adapter is used as part of the MIPS jazz machine, however
I don't have a working kernel and system to test it with. Any pointers to
test images would be appreciated.
- The changes to the PROM checksum in patch 3 were determined by stepping
through the MacOS toolbox, and is different from the existing algorithm.
Has the current PROM checksum algorithm been validated on a MIPS guest or
was it just a guess? It might be that 2 different algorithms are needed for
the Q800 vs. Jazz machine.
- My current guess is the jazzsonic driver is broken since the last set of
dp8393x changes as the MIPS jazz machine does not set the "big_endian"
property on the dp8393x device. I'd expect that the following diff would
be needed, but I can't confirm this without a suitable test image.
