Just from a quick glance at the part that wasn't truncated, I
notice all the inline asm stuff is wrong -- it duplicates what's
already available in cpu-v6.h.
I had a conversation with Andrew this morning, he pointed me out
those defines in cpu-v6.h, but we agreed those are optional stuff.
I.e. duplicates != wrong. I'll fix that. Thanks
It would be useful to use them, but this will need Makefile changes as
some of these defines are only available when __ARM_ARCH > 6 which may
not be true in userland. If we do make these changes we then need to
make sure that none of the code on the file built as ARMv7 is run on
an
ARMv6 as the compiler may choose to use invalid instructions on v6.
I gather what is referred to here as defines are the macros that Ian (I
think)
added for access to the pmc and other fancy registers? I see that the
hwpmc code
has asm directly in it.
Best,
George
