From 8bb00d83d8fc2de5c0614f5d55780107e0c375fe Mon Sep 17 00:00:00 2001 From: Ralf Baechle Date: Tue, 16 Oct 2007 11:35:11 +0100 Subject: [PATCH] [MIPS] Increase cp0 compare clockevent min_delta_ns from 0x30 to 0x300. Extremly low values are of dubious usefulness anyway but in this case they actually were killing Qemu which simply wasn't able to complete mips_next_event() within 0x30 100MHz cycles even on fast hosts.
