From b30a47b841f1c7d55d9cf207e1cc89f1b7f7fa51 Mon Sep 17 00:00:00 2001 From: Patrick Rudolph Date: Mon, 15 Jul 2019 18:04:23 +0200 Subject: sb/intel/{bd82x6x|ibexpeak}: Drop p_cnt_throttling_supported The processor P_BLK doesn't support throttling. This behaviour could be emulated with SMM, but instead just update the FADT to indicate no support for legacy I/O based throttling using P_CNT. We have _PTC defined in SSDT, which should be used in favour of P_CNT by ACPI aware OS, so this change has no effect on modern OS. Drop all occurences of p_cnt_throttling_supported and update autoport to not generate it any more.
