Can I help maybe? Power management isn't the next step on the roadmap: we have to handle i915 and the device-independent part before upgrading the Radeon driver again. We also need to work on vt(4), the new console driver. This will help with moving on with the "NEW_XORG" stack (which is getting old...). If you're willing to help and are interested in kernel development, you could look into either problems with the GPU drivers or missing features in vt(4). Here are some ideas: 1. With Radeon cards, Piglit, the Mesa testsuite, freezes at some point. This is 100% reproducible on my laptop and this is always with the same tests. You would need to run Piglit (all dependencies are in the ports tree, except piglit itself which evolves too quickly to deserve a port). 2. With either Radeon or i915, when we vt-switch from the console back to the X session, the screen is frozen for up-to 10". It looks like we don't restart something and a timer implicitely does it. 3. In vt(4), we are missing several features. Here are two which were requested by testers (there are probably other requested features of course): o text cursor blinking o vidcontrol -[hHpH] Playing with vt(4) is probably easier to start with if you never did kernel development, as the code is way simpler and shorter than the DRM component. Let me know if you want to work on this! --=20 Jean-S=C3=A9bastien P=C3=A9dron --PkW0imS5C1MbREuluQas8qAQMHNnpHO5X Content-Type: application/pgp-signature; name="signature.asc" Content-Description: OpenPGP digital signature Content-Disposition: attachment; filename="signature.asc" -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iQJ8BAEBCgBmBQJUBzRhXxSAAAAAAC4AKGlzc3Vlci1mcHJAbm90YXRpb25zLm9w ZW5wZ3AuZmlmdGhob3JzZW1hbi5uZXQ2NzA4N0ZEMUFFQUUwRTEyREJDNkE2RjAz OUU5OTc2MUE1RkQ5NENDAAoJEDnpl2Gl/ZTM0R0QAJ8DdbmzjqQRnb4pmqxH4lQd AkAoHxu5HmblsC1TJkkj/H6STrbeSgkUaCnlyBhkuf45B+s0hSwBdvDGRCaxvOXn iNwdZ1C1pGuwaHWjnRGAFDZdBA07WE77nQxyV+/s3aPSnkPuDZ0ABmnD2OseSQSS tYjW8hqjUEgevLpNRkEO+uAYceo6xZ30XCEyDxd2ntaQblK2zwP27QkyqNZ8e757 /+aEADffCfoa/NfcJoOllpyXk6mG+1v8lvPF4xlEBGw4wcdmzwvNKxaKqJgNx+gh ocB/8l4xkNMlbEVd0qBSAiGV+sO5rbb5vegVIFIh8IOISyxSQG8Vh5FkHUBPyNiX /aT3jnWxGXwnilgzPvGT7uzlVkJwYy868fRQgmLLyBRoOCUhWP2kBWaA4+MXhLxP 57Duw3Dqo+S2NE3kGkI3mKxtbf4O5IC01stZYISgItWsyqxJFWVewSd0nqXxNuhD AVRoZb1GsweHzFkfh3vOuIrk+puj/PyFrqTj316Bn9lKBTkZbWMkhz8MIPAku9HG jhh0zstG/XrJGs7nRJIEulV9u6o1QdAx44KZHICEpYpucDFDxs1scPgdmdyxlrN+ yGLm841oMvViU9Mia+sQ21oGVwmf4xtDH0TOU7bJcmuuo2t0HWKuebvZKiMhIVQl dJDGyziVXZ0IHAo0tUpC =pbcy -----END PGP SIGNATURE----- --PkW0imS5C1MbREuluQas8qAQMHNnpHO5X--
