1. 요약·해설
원문의 핵심 논리와 kernel programming 관점의 보충 설명입니다. 아래의 전문 번역과는 별도로 작성했습니다.
Client and server critical limits
sysfs-driver-intel-i915-hwmon:40-65Client 제품은 power1_crit microwatts, server 제품은 curr1_crit milliamperes로 I1 critical limit을 설정합니다.
Energy, fan and temperature telemetry

Description: RW. Card reactive sustained (PL1/Tau) power limit in microwatts.
15
The power controller will throttle the operating frequency
16
if the power averaged over a window (typically seconds)
17
exceeds this limit. A read value of 0 means that the PL1
18
power limit is disabled, writing 0 disables the
19
limit. Writing values > 0 will enable the power limit.
