Hi,
just a little question about armv7 configs.
Recent kernel configs have disabled CONFIG_SWP_EMULATE (Emulate SWP/SWPB instructions). Is it on purpose? Do we need it for anything? We don't have legacy user space code we need to keep running, no?
I think XBMC make still use of it. But there is not yet openSUSE XBMC package.
Really? Why would it? It's a legacy opcode that slows you down fwiw. It'd be good to fix XBMC then. Alex
Moreover we have not enabled ThumbEE CPU extension (CONFIG_ARM_THUMBEE). Should we enable it? FWIW Thumb EE is only necessary for special JVMs that generate Thumb EE code. But yes, apparently it's part of ARMv7, so we should at least allow user space to make use of it.
Ok.
