Hello, This series exposes global performance counters (PCOUNTER) to the userspace through the nvif interface by reworking most of the code related to the PM engine. This interface will allow the userspace to control and monitor complex hardware events like the proprietary driver already does, for example with CUPTI and PerfKit. For now, this series only exposes performance counters on NV50,

Hi, This is a batch of patches touching drm for preparing for the coming implementation by GCC and Clang of the __counted_by attribute. Flexible array members annotated with __counted_by can have their accesses bounds-checked at run-time checking via CONFIG_UBSAN_BOUNDS (for array indexing) and CONFIG_FORTIFY_SOURCE (for strcpy/memcpy-family functions). As found with Coccinelle[1], add

Hi folks, This set of patches is just for clearing the way before introducing the infrastructure for performance counters in perfmon. I'll try to publish a new version of my kernel interface based on nvif in a couple of days. See you.

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,
