2022-10-03hw/core/cpu-sysemu: used cached class in cpu_asidx_from_attrsAlex Bennée
This is a heavily used function so lets avoid the cost of CPU_GET_CLASS. On the romulus-bmc run it has a modest effect: Before: 36.812 s ± 0.506 s After: 35.912 s ± 0.168 s Signed-off-by: Alex Bennée <alex.bennee@linaro.org> Reviewed-by: Richard Henderson <richard.henderson@linaro.org> Message-Id: <20220811151413.3350684-4-alex.bennee@linaro.org> Signed-off-by: Cédric Le Goater <clg@kaod.org> Message-Id: <20220923084803.498337-4-clg@kaod.org> Signed-off-by: Richard Henderson <richard.henderson@linaro.org>

2021-05-26cpu: Introduce cpu_virtio_is_big_endian()Philippe Mathieu-Daudé
Introduce the cpu_virtio_is_big_endian() generic helper to avoid calling CPUClass internal virtio_is_big_endian() one. Similarly to commit bf7663c4bd8 ("cpu: introduce CPUClass::virtio_is_big_endian()"), we keep 'virtio' in the method name to hint this handler shouldn't be called anywhere but from the virtio code.
