EMUPLT takes its toll as usual, but i forget the exact numbers |
9 |
now (was 1.5 years ago when i last touched the ppc port), could |
10 |
very well be 50-100%. if userland is cleaned up (.plt is no longer |
11 |
runtime generated) this should be much less. |

there's only PAGEEXEC on ppc (and ppc64), PaX doesn't use the ppc |
16 |
segmentation logic, it's too coarse grained. |

i think only 4xx has explicit hardware NX support and the mainline |
26 |
linux kernel doesn't really use it there nor do i have access to such |
27 |
boards, so they're not supported as of now. the other models have |
28 |
implicit support for the per-page NX bit and PaX uses that, although |
29 |
noone has ever reported back on ppc64 yet. |
