MiniPerf

Example of how to capture CPU counters with ETW on Windows, perf on Linux or kperf on Apple.

Using ETW needs somewhat recently updated Windows 10 or 11. Not sure about exact version.

Currently tested on:

• etw on Qualcomm Snapdragon X Elite, Windows 11, arm64
• etw on AMD Zen 3, Windows 11 (with virtualization enabled in BIOS)

Random Mach notes

mach_thread_self increments ref count

Each call to mach_thread_self adds another MACH_PORT_RIGHT_SEND refcount. For each call to mach_thread_self, you need to call mach_port_deallocate on the result.

(This does not apply to mach_task_self.)

Minimal D3D11

Minimal D3D11 reference implementation: An uncluttered Direct3D 11 setup + basic rendering primer and API familiarizer. Complete, runnable Windows application contained in a single function and laid out in a linear, step-by-step fashion that should be easy to follow from the code alone. ~200 LOC. No modern C++, OOP or (other) obscuring cruft. View on YouTube
