Hi everyone,
I apologise if this is considered off-topic, however I'm aware that there are many
people on this list with years of experience of PPC CPUs who may be able to help.
As part of my work on the QEMU Mac machines, I've been working on an implementation
of BLRM "Byte Lane Reverse and Munge" [1] to support a developer working on running
WinNT PPC under QEMU.
Whilst the patch is fairly complete, the problem I have is that there doesn't appear
to be a concise list of CPUs that use BLRM (as opposed to proper LE memory accesses)
when MSR_LE is enabled.
From what I can gather all 64-bit CPUs use proper LE memory accesses, but it's not
clear whether for 32-bit CPUs the use of BLRM can be derived from the PVR or other
CPU registers.
Can anyone provide any insight as to which CPUs make use of BLRM for MSR_LE? For
reference the 32-bit CPUs emulated by QEMU are as follows:
$ ./build/qemu-system-ppc -cpu ?
