2021-07-21qemu/atomic: Add aligned_{int64,uint64}_t typesRichard Henderson1-1/+1
Use it to avoid some clang-12 -Watomic-alignment errors, forcing some structures to be aligned and as a pointer when we have ensured that the address is aligned.

2021-04-01icount: get rid of static variablePavel Dovgalyuk1-0/+2
This patch moves static last_delta variable into timers_state structure to allow correct vmstate operations with icount shift=auto enabled.

2020-10-05cpu-timers, icount: new modulesClaudio Fontana1-0/+69
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.
