[Qemu-devel] [PATCH 20/37] target-i386: Remove setting tsc-frequency from x86_def_t |
Date: |
Mon, 28 Jan 2013 17:18:37 +0100 |
From: Igor Mammedov <address@hidden>
Setting tsc-frequency from x86_def_t is NOP because default tsc_khz
in x86_def_t is 0 and CPUX86State.tsc_khz is also initialized to 0
by default. So there is no need to overwrite tsc_khz with default 0
because field was already initialized to 0.
Custom tsc-frequency setting is not affected due to it being set
without using x86_def_t.
Field tsc_khz in x86_def_t becomes unused with this patch, so drop it
as well.
