If so, yes, you really do need good userland for KMS to work. >=20 > BTW, Is suspend generally supposed to work with KMS and the 2.6.1 (or lat= er) X > driver? I pulled a giant pile of KMS bugfixes into 2.6.2, so I'm not sure about 2.6.1. We've still got some work to do with making our suspend/resume path really complete for KMS. We're missing some register setup that UMS does, so behavior can be a bit random. The current plan is to switch to using the KMS modeset paths for resume, so we hopefully have reliable (or at least consistent) mode setting behavior, and then fill those remaining register writes in around it. Basically, a separate suspend/resume path for KMS, when we have full control of the device. --=20 Eric Anholt eric-WhKQ6XTQaPysTnJN9+BGXg@public.gmane.org eric.anholt-ral2JQCrhuEAvxtiuMwx3w@public.gmane.org --=-zyLXdcwe2xV8U98OmqfH 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) iEYEABECAAYFAkm2pCwACgkQHUdvYGzw6vcHuwCfQuIEjQk/sJCwLtvkL5K5SBMp /30An3IpC4q01nOh0Vq4C4wasjNq9Kv5 =Nk09 -----END PGP SIGNATURE----- --=-zyLXdcwe2xV8U98OmqfH--
