From 092fe558ee20950faf29d8e7d581a2631e6e1bb4 Mon Sep 17 00:00:00 2001 From: =?UTF-8?q?Ky=C3=B6sti=20M=C3=A4lkki?= Date: Fri, 1 Nov 2019 07:13:09 +0200 Subject: [PATCH] intel/i440bx: Switch to UDELAY_TSC and TSC_MONOTONIC_TIMER MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Note that due to UNKNOWN_TSC_RATE, each stage will have a slow run of calibrate_tsc_with_pit(). This is easy enough to fix with followup implementation of tsc_freq_mhz() for the cpu.
