Thank you very much. I have implemented the AT_PLATFORM, therefore all 2.6.16 (and later)=20 i386/amd64 auxvecs are implemented, except for AT_SYSINFO and=20 AT_SYSINFO_EHDR that are i386-specific and provide optional way of=20 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=20 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=20 -current. It is also trivial to port to 64-bit amd64 emulation. --Marcin --------------enigA19EF0E5CE03EC51E963D795 Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- iQCVAwUBSHe6uz2W2v2wY27ZAQNH1wQAk4BD1WAcfGJV/BQmNIR6GKniI5gF0CrI vaVwJCv2HKHvhqY51yf5Rbzxni3Dshye/2ozaS6nozNIJn79XZ7oCv4Wn95YllNW dZ6ocli+so6XUT2hUXrjE9raE9mqGVcgRqcdI1WZj6rPh58B1hqbvIHomUoHDk7q x0wo7VV8TH0= =hlz7 -----END PGP SIGNATURE----- --------------enigA19EF0E5CE03EC51E963D795--
