Changes to make m5ops work under virtualization seemed to break them working
with non-virtualized systems and the recently added m5 fail command makes
the m5op binary not compile. For now remove the code for virtualization.
Changeset 5ca6098b9560 accidentally broke the m5 utility. This
changeset adds the missing co-processor call used to trigger the
pseudo-op in ARM mode and fixes an alignment issue that caused some
pseudo-ops to leave thumb mode.
This changeset adds support for m5 pseudo-ops when running in
kvm-mode. Unfortunately, we can't trap the normal gem5 co-processor
entry in KVM (it doesn't seem to be possible to trap accesses to
non-existing co-processors). We therefore use BZJ instructions to
cause a trap from virtualized mode into gem5. The BZJ instruction is
becomes a normal branch to the gem5 fallback code when running in
simulated mode, which means that this patch does not need to change
the ARM ISA-specific code.
Note: This requires a patched host kernel.
Usage: m5 writefile <filename>
File will be created in the gem5 output folder with the identical filename.
Implementation is largely based on the existing "readfile" functionality.
Currently does not support exporting of folders.
