--nfvf/JXVyOeI7XiA Content-Type: text/plain; charset=utf-8 Content-Disposition: inline Content-Transfer-Encoding: quoted-printable Just a quick report that from my completely unscientific observations it seems that battery life is extended with the latest drm import on my Thinkpad X230. I should probably get some numbers first, but my gut feeling is that it is better. By the way on the X230 (IvyBridge i7) the loader.conf setting "drm.i915.enable_rc6=3D7" makes a huge difference. For some other reason I removed it from loader.conf and hw.acpi.battery.time showed 160 minutes. After re-adding it battery time went up to 230 minutes.=20 Lars --nfvf/JXVyOeI7XiA Content-Type: application/pgp-signature -----BEGIN PGP SIGNATURE----- Version: GnuPG v2 iQF8BAEBCgBmBQJU0oC1XxSAAAAAAC4AKGlzc3Vlci1mcHJAbm90YXRpb25zLm9w ZW5wZ3AuZmlmdGhob3JzZW1hbi5uZXQ4RjQwMDE3RTRERjUzMTI1N0FGRTUxNDlF NTRDQjM3RDNBMDg5RDZEAAoJEOVMs306CJ1tsmQIAMEYzJvxdnTqcZaGuBNtBqfO 3Kg9xVm2gbk6iXTu5u+YIp/0d4H5ok9M9rGFJ9jtOVkFsD4/vH620Q/eS2KBS6zm /JbAIpo1YOOo+kl9r9eVcukqsstOE++/XoATYXy9mo9u3lEgyT2Umbgh/7uPMmRi HEffqHkIUzi4kjFD/NiovH3Y64pm+QuR82jJaSkugehlecoiXVJdxN8PerK9WFPY 61Y0Xo/6uaCVxWw8SI7QNoEktmL6TjG7ejzpnMsgd3ZWqP1aMeceX3P5H5QoaOKr c7P6PXva3rWJu9rYXHZXJcgx/Ufq/J5G0mj1M8Gja0mWzZ3889C11ViSFddbQV4= =lhqn -----END PGP SIGNATURE----- --nfvf/JXVyOeI7XiA--
