2020-10-05cpus: extract out qtest-specific code to accel/qtestClaudio Fontana1-50/+0
register a "CpusAccel" interface for qtest as well. Signed-off-by: Claudio Fontana <cfontana@suse.de> Reviewed-by: Richard Henderson <richard.henderson@linaro.org> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2020-10-05cpu-timers, icount: new modulesClaudio Fontana1-5/+1
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.

2019-05-02qtest: Don't compile qtest accel on non-POSIX systemsEduardo Habkost1-1/+0
qtest_available() will always return 0 on non-POSIX systems. It's simpler to just not compile the accelerator code on those systems instead of relying on the AccelClass::available function.

2019-05-02qtest: Move accel code to accel/qtest.cEduardo Habkost1-0/+55
QTest has two parts: the server (-qtest) and the accelerator (-machine accel=qtest). The accelerator depends on CONFIG_POSIX due to its usage of sigwait(), but the server doesn't. Move the accel code to accel/qtest.c. Later we will disable compilation of accel/qtest.c on non-POSIX systems.
