The driver knows best. Tunables are generally the worst solution. I agree, but what about the not so ideal real-world? What about closed sour= ce=20 drivers? Who is going to educate closed source driver writers to inform the= =20 kernel about their memory requirements early enough? And how long will this= =20 take? I think at least as an interim measure it makes sense to have a sysfs value= =2E=20 Or discourage closed-source drivers even more. I prefer open-source gfx drivers and don't need extra pages allowance, but= =20 that might not hold true for everyone. =2D-=20 Martin Steigerwald - team(ix) GmbH - http://www.teamix.de gpg: 19E3 8D42 896F D004 08AC A0CA 1E10 C593 0399 AE90 --nextPart4710087.X9GrhZ40pD Content-Type: application/pgp-signature; name=signature.asc Content-Description: This is a digitally signed message part. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.9 (GNU/Linux) iEYEABECAAYFAkodUHUACgkQHhDFkwOZrpDmlgCfV1MuUTij216v9Sf7c6Fw4HwB 2oQAn02qnn09In43E/RCtqQcYFvF1FhV =gzej -----END PGP SIGNATURE----- --nextPart4710087.X9GrhZ40pD--
