IMHO this is wrong for different reasons: 1) the latest AGP and DRI driver for my ATI Radeon Mobility NP M10/9600 works great on my ASUS M6842NWH (Centrino) at least for S1 [1] (I haven't had time to test S3/S4 yet), so this means that there's PM support for some AGP/DRI drivers... BTW, to answer Huw about ATI drivers, I use the *open-source* DRI ones [2] and they work perfect but 3D/OpenGL (which I don't use as I don't have time to play): I can have dual-head (LCD 1400x1050 and CRT 1600x1200), clone mode, Xinerama or MergedFB and DVD full screen... 2) the same new 2.6 'radeonfb' driver has PM implementations, even if it needs more work, as reported in this list ([3] and [4]) 3) USB *has* working PM support at least in 2.6.5-rc2 [5] (search for "[PATCH] USB: Enable interrupts in UHCI after PM resume") 4) AFAIK some ALSA driver can suspend/resume [6] 5) I don't know a lot about network driver, but I know of PM implementations [7] on 'e1000' and 'ipw2100' drivers and during my tests, I never remove the 'bcm5700' module (and this doens't cause any resuming problem) Thx, bye, Gismo / Luca ===== References: 1- http://marc.theaimsgroup.com/?l=acpi4linux&m=107989959514312&w=2 2- http://dri.sourceforge.net/cgi-bin/moin.cgi/ATIRadeon 3- http://marc.theaimsgroup.com/?l=acpi4linux&m=107731507729859&w=2 4- http://marc.theaimsgroup.com/?l=acpi4linux&m=107752252801966&w=2 5- ftp://ftp.kernel.org/pub/linux/kernel/v2.6/testing/ChangeLog-2.6.5-rc2 6- http://sourceforge.net/mailarchive/forum.php?thread_id=4107033&forum_id=1752 7- http://sourceforge.net/mailarchive/forum.php?thread_id=4075032&forum_id=38938 -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.4 (GNU/Linux) Comment: Using GnuPG with Debian - http://enigmail.mozdev.org iD8DBQFAarnaVAp7Xm10JmkRAkBYAKCD2c0RMU86Pbnb59YbgKs1zyeafQCbBPM4 xh2ota1KMneGFg3G4f0XUIE= =e0Kd -----END PGP SIGNATURE----- ------------------------------------------------------- This SF.Net email is sponsored by: IBM Linux Tutorials Free Linux tutorial presented by Daniel Robbins, President and CEO of GenToo technologies.
