[Gems-users] invalidating a cache block

[Mladen Nikitovic <mladen@xxxxxx>]

Hi,

I would like to go through a cache and invalidate each entry 
block-by-block. I would like to do it in a way such that necessary 
events within ruby (replacements if needed) are triggered.
I found a code in opensolaris that is supposed to flush the cache (see 
below) but I suppose that the instruction stxa will not trigger the 
expected events in GEMS?
#define CH_CACHE_FLUSHALL(arg1, arg2, tmp1)

 sub arg1,arg2,tmp1;
1:
 stxa %g0, [tmp1]ASI_DC_TAG;
 membar #sync;
 cmp %g0, tmp1;
 bne,pt %icc, 1b;
 sub tmp1, arg2, tmp1;


I'm using the MOESI_CMP_directory protocol.

Thanks.

Regards,
Mladen
