Hello there, This series exposes NVIDIA's global performance counters for Tesla through the Gallium's HUD and the GL_AMD_performance_monitor extension.
This adds support for 24 hardware events which have been reverse engineered with PerfKit (Windows) and CUPTI (Linux). These hardware events will allow developers to profile OpenGL applications. To reduce latency and to improve accuracy, these global performance counters are tied to the command stream of the GPU using a set of software methods instead of ioctls. Results are then written by the kernel to a mapped notifier buffer object that allows the userspace to read back them. However, the libdrm branch which implements the new nvif interface exposed by Nouveau and the software methods interface are not upstream yet. I hope this should done in the next days. The code of this series can be found here: http://cgit.freedesktop.org/~hakzsam/mesa/log/?h=nouveau_perfmon The libdrm branch can be found here: http://cgit.freedesktop.org/~hakzsam/drm/log/?h=nouveau_perfmon The code of the software methods interface can be found here (two last commits): http://cgit.freedesktop.org/~hakzsam/nouveau/log/?h=nouveau_perfmon An other series which exposes global performance counters for Fermi and Kepler will be submitted once I have got enough reviews for this one. Feel free to make a review. Thanks, Samuel.
