Hi, I am using solve.QP (from quadprog) to solve a standard quadratic programming problem: min_w -0.5*w'Qw st ... I would like solve.QP to do two things: 1) to start the optimization from a user-supplied initial condition; i.e., from a vector w_0 that satisfies the constraints, and 2) to return the values of the lagrange multiplieres associated with the constraints. I did not find an obvio...

There is an optinal header field in the power budget table we can use to read out the power cap of the GPU. We should have this in the kernel before actually using it to catch errors and see how reliable this is, but as it seems it works on all GPUs as expected on Kepler und Maxwells with the power cap field set in the vbios. This series keeps things really simple for now until we figure out

There is an optinal header field in the power budget table we can use to read out the power cap of the GPU. Sadly it is optional and if that field isn't sad, things beome complicated. Anyhow, this is good enough for most cards and we can use it later for capping the power consumption of the GPUs, but first, just export those values through hwmon. First design, will change stuff, want

There is an optinal header field in the power budget table we can use to read out the power cap of the GPU. The meaning of this header field was confirmed with nvidia-smi -q: The rows "Min Power Limit", "Power Limit" and "Max Power Limit" are set to the "min", "avg" and "max" values from the referenced power budget entry respectively.
