https://bugs.freedesktop.org/show_bug.cgi?id=99505 Bug ID: 99505 Summary: Attempting to reclock GeForce GT740M (GK208) cause GPU and system to hang Product: xorg Version: unspecified Hardware: Other OS: All Status: NEW Severity: normal Priority: medium Component:

I've splitted my big series between the part which actually fixes the engine reclocking bits and the part handling voltage/clock updates on temperature change, so that the more reviewed parts can be merged in faster. This series fixes a lot of Engine reclocking issues found on Fermi, Kepler and all Maxwell generation GPUs. It does _not_ fix memory reclocking on Fermi. It mostly contains of

This series fixes most of the issues regarding volting on GPUs with any form of GPU Boost inside their vbios, which is mainly Kepler and newer, but we find some boosting related tables in Fermi vbios' already In the end reclocking should work on most Kepler cards without any issues v2: boost_mode can now be changed at runtime minor fixups Karol Herbst (22): bios/volt: handle voltage
