Thank you very much. I have implemented the AT_PLATFORM, therefore all 2.6.16 (and later) i386/amd64 auxvecs are implemented, except for AT_SYSINFO and AT_SYSINFO_EHDR that are i386-specific and provide optional way of invoking linux syscalls (using so-called virtual dynamic shared object). I think we don't need those. The code is completely untested on i386. My first attempts show that skype and acroread8 launch faster (probably due to the "hz" effect). The patch is here: http://akson.sgh.waw.pl/~saper/FreeBSD/linux/auxvec.diff This was made against 7-STABLE, but there no major differences in -current. It is also trivial to port to 64-bit amd64 emulation. --Marcin [-- Attachment #2 --] -----BEGIN PGP SIGNATURE----- iQCVAwUBSHe6uz2W2v2wY27ZAQNH1wQAk4BD1WAcfGJV/BQmNIR6GKniI5gF0CrI vaVwJCv2HKHvhqY51yf5Rbzxni3Dshye/2ozaS6nozNIJn79XZ7oCv4Wn95YllNW dZ6ocli+so6XUT2hUXrjE9raE9mqGVcgRqcdI1WZj6rPh58B1hqbvIHomUoHDk7q x0wo7VV8TH0= =hlz7 -----END PGP SIGNATURE-----
