From 740b175973427bcfa32ad894bb1f83b96d184c28 Mon Sep 17 00:00:00 2001 From: Claudio Fontana Date: Wed, 19 Aug 2020 13:17:19 +0200 Subject: cpu-timers, icount: new modules refactoring of cpus.c continues with cpu timer state extraction. cpu-timers: responsible for the softmmu cpu timers state, including cpu clocks and ticks. icount: counts the TCG instructions executed. As such it is specific to the TCG accelerator. Therefore, it is built only under CONFIG_TCG. One complication is due to qtest, which uses an icount field to warp time as part of qtest (qtest_clock_warp). In order to solve this problem, provide a separate counter for qtest. This requires fixing assumptions scattered in the code that qtest_enabled() implies icount_enabled(), checking each specific case.
