Is it SPARC-only or can you do it on x86 too? I only used it on SPARC systems - I didn't read the man page close enough to see whether it was restricted to that architecture. > I'm also wondering if that's just the size of the *software* pages, or > hardware paging structures, too. Unfortunately, the documentation didn't explain this. Of course, such an option only helps if it decreases the demand on the TLB. Because the TLB caches translations between virtual and physical addresses, I surmise that it would only work for "hardware paging structures". But as I indicated in my previous e-mail, my knowledge of kernel programming is two decades out of date, so I might be (way) off.
