The i915 driver never publishes per-client usage counters on GPUs older than Broadwell, so Haswell and older users got a warning telling them to upgrade to kernel 6.5 even on 6.12. The warning and docs now state the Broadwell requirement alongside the kernel 6.5 requirement for 12th gen and newer.

Frigate reads Intel GPU utilization directly from the kernel's per-client DRM usage counters exposed at `/proc/<pid>/fdinfo/<fd>`. This requires:
- Linux kernel **5.19 or newer** for the `i915` driver, or any release of the `xe` driver.
- An Intel GPU from Broadwell (5th gen) or newer. Older GPUs do not expose these counters on any kernel.
- Linux kernel **5.19 or newer** for the `i915` driver (**6.5 or newer** on 12th gen and newer), or any release of the `xe` driver.
- Frigate running with permission to read other processes' fdinfo. Running as root inside the container (the default) satisfies this; non-root setups may need `CAP_SYS_PTRACE`.
No `intel_gpu_top` binary, `CAP_PERFMON`, privileged mode, or `perf_event_paranoid` tuning is required.
