Subject: [Qemu-devel] Cortex-M4F Floating Point system registers
Date: Wed, 20 Mar 2013 17:05:10 +0100 [thread overview]
Message-ID: <5149DE36.3060301@adacore.com> (raw)
Hello QEMU ARM folks,
I'm looking at the ARMv7-M profile and the implementation in QEMU.
Looks like M3 is supported and I'd like to work on M4F (FP context save
and lazy FP context save).
I wonder how the FPU system registers, and more generally how the
co-processor registers are implemented in QEMU.
For example in the Cortex-M4 TRM it seems like FP system registers are
mapped in memory. I don't see that implemented in QEMU.
Thanks,
