It is a good idea and for new cpus it is probably an option. For people in the embedded space we still need romcc. > Is there any intel public doc about using cache_as_ram? I have not seen any yet which is a puzzle. For the first round of Intel cpus that supported it you had to load a microcode update, before it would work. I have yet to see if AMD's flavor will work on k8 revisions B3, C0, CG, Ex. I expect it will but I have been burnt too many times. > I have tried amd cache_as_ram in intel platform, it seem if access > some position several times, the contents of that address will become > to 0xff.... Exactly the problem. If you aren't using a supported flavor of cache as ram it fails more often and in less predictable ways than romcc. That is why I avoid it unless the manufacturer supports it. And that is why we cannot decompress and run code out of the cache.
