What are you referring to? I have a copy of the PEM from pre-G3 days, and a copy that I downloaded just now, and neither of them have an N bit in the PTE (and yes I just looked carefully through pages 7-38 and 7-39). There is an N bit in the segment register format, and that's what Albert is using. As far as the documentation goes, you can make the page readable and writable to the LSU, but the N bit causes the instruction fetch to cause a machine check. That's pretty not-executable to me at least :) A machine check is nasty, because it may not be recoverable... I agree, but I don't know why you believe it would cause a machine check (0x200): from my docs, it is an ISI (0x400). BTW, there is one way to make pages non executable: mark them as guarded, but it will have a significant cost in terms of performance. I never understood why PTE entries waste 4 bits (WIMG) for effectively very few valid combinations. Regards, Gabriel -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe.

Indeed. I guess we could do that as a config option for machines that really want maximum security at the expense of performance, but I don't think all users would want that. On the other hand, if you want to squeeze some performance out of the chip, turn off coherency. (probably not for SMP) I've done it before, with a non-Linux OS. It does help. Other tricks are to map userspace via BATs and, on the 7410 at least, to map half or all of the outermost cache memory as a special block of high-speed memory. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe.

Re: PowerPC paxtest results w/ gcc-4.1
I never understood why PTE entries waste 4 bits (WIMG) for effectively very few valid combinations. The only invalid combinations are WI=11 -- if you know of a way to fit 12 combinations in fewer than 4 bits, let us know :-) Not all of those 12 are very useful, of course.

Re: [PATCH] no-execute -- please test
We have a bit per page that says if the page is icache dirty or not. On machines with no-execute support, we already avoid flushing the page until some process first tries to execute from it. If we extended that to this scheme, when we made a segment executable, we would have to find and flush all icache-dirty pages in the segment (up to 65536 pages). We wouldn't want to do that every time we made a segment executable - it would need to be optimized (e.g. keep a count per segment of icache-dirty pages in the segment). Note that we need to change the icache flush mecanism anyway as it's always been racy on ppc32 SMP (though very few people noticed so far :) and ppc64 SMP with POWER3 CPUs (without N bit).
