In the console, as root, can you: $ cat /sys/kernel/debug/dri/0/i915_cur_delayinfo | grep Lowest then echo that value into the max freq file, e.g.: $ echo 400 > /sys/kernel/debug/dri/0/i915_max_freq then try logging in and doing stuff. If that fixes your fan issue, it means the GPU frequency is to blame. I think Eugeni is working on a nice API to let users control perf vs power a bit better than our current default of "try to run as fast as possible under any load, even a tiny one". --=20 Jesse Barnes, Intel Open Source Technology Center --Sig_/aGh7m3oGpYt8isqzAPaeped Content-Type: application/pgp-signature; name=signature.asc Content-Disposition: attachment; filename=signature.asc -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.4.10 (GNU/Linux) iQIcBAEBAgAGBQJO58JEAAoJEIEoDkX4Qk9h9dYQAK4TtcCS8I3e8RRCx4SoGfOO oqSOELlrqisSmuqq8ivYTiuQPzhHyx+M2zKYfEOCe1zBaUkyBwPInC8bPCs22UZH OCn2yV9O5uR78ofVzxkhw2xaDMTQdB+Ihzx21kuU8VgzqZob2HU3ZLi5LNWr2QyQ Xl8jRL2vIBrX/a4aAFJi0qD+TGk9QuqmxEGp980lA48SNVZACccLuLJdA3SBaw/a /q04YeYFSfHicZzAHoQnAK5gd2/xdioOYxESW1o+6nOe+qR90KjGgl03qqGKMI7d TJ6dphGgRQNXw85Wv5+SBZT/KIzudfMZ9x/GIJ5xbmHQBymDvrnxm/nrkzU0TOrk fxhSBWCVGNydjREOD0EeKX+7Vav9tT5LpnbA06uAeLYanGCpzYZBmVNDxomfxO/X FRa064faYe7HJ4SuenwyVmKxPoyzfxw/cwOl3+38Xyqmo6g4LInHEb47bWaTjpRL uH2g+IrRBwNfpwEFtWUKcU9mYdWGkpdutd0snSlO0WQgTHoH7rMmiRb94OoJVdR0 NQ5T+NNNOOSGvC24F5LL0OfR0wMpPVd3/I4Zl8IrT0ftoKzJ+gGJii8O8V/kVjRf S6Dqm5HcsIrelDBt1mtRH7lGQ/2wH2MaK97Oe6xkcKKvY3VsdSUblrhAG36v/XDd /B+7Jzat4GehxB16nmsq =wSLh -----END PGP SIGNATURE----- --Sig_/aGh7m3oGpYt8isqzAPaeped-- --===============1073683287== Content-Type: text/plain; charset="us-ascii" MIME-Version: 1.0 Content-Transfer-Encoding: 7bit Content-Disposition: inline _______________________________________________ Intel-gfx mailing list Intel-gfx@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/intel-gfx --===============1073683287==--
