Hi Fernando, Gabriel,
The timing is in cycles indeed, and the L1 and L2 caches are by default
inheriting the CPU clock. Check the config.ini/config.json to ensure it has the
value you expect. The latter will show you the clock period and resulting
latency in ns.
The arm_detailed configuration is using a different cache configuration. See
configs/common/O3_ARM_v7a.py

Subject: Re: [gem5-users] Units for gem5/configs/common/Caches.py?
Hello,
As far as I know, timings are in cpu cycles, so the latency and
response_latency. And block_size is in bytes.
It's better recopying these configs in the gem5's command line when possible.
Regards,

Below is taken from Caches.py. In what units are hit_latency and
response_latency? Cycles? nanoseconds?
Also, are these the numbers that are used when the detailed version of arm is
used? (using the default cache configurations with the classic memory subsystem)
class L1Cache(BaseCache):
assoc = 2
hit_latency = 2
response_latency = 2
block_size = 64
mshrs = 4
tgts_per_mshr = 20
is_top_level = True
