I looked at http://msdn.microsoft.com/en-us/library/aa489566.aspx after someone mentioned ndisulator. It seems that windows requires that i386 drivers carefully use braces for use of FPU, while amd64 code allowed to use it freely. That suggests that windows clears TS on kernel mode entry or driver calls, that seems to be too wastefull. I would very much appreciate the help with changing both ndis and padlock to use fpu_kern_enter/leave KPI, since I do not use them. I need some time to polish the patch before. --f61P+fpdnY2FZS1u Content-Type: application/pgp-signature Content-Disposition: inline -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.10 (FreeBSD) iEYEARECAAYFAkupHm0ACgkQC3+MBN1Mb4gZrACg8DoPl2jtGLRsr2vKymLRiO4z Q5sAoIpz34Wt9kNiqjI5gR0hd6Ueer1T =zYmq -----END PGP SIGNATURE----- --f61P+fpdnY2FZS1u--
