The datasheet does not provide information on cache sizes. Given that the A113X/A113D are equipped with the Arm Cortex-A53 processor, it is assumed they use the same cache size as the S905/S905X/S905X2 models. > > GXM is also missing, and also using A53 cores. > > Christian > This patch is valid if the hardware supports perf PMU events, see below I dont have the hardware. Best way to let the Amlogic SoC members comment on the CPU L1/ /L2 cache size. But with the lack of pref PMU events we cannot test this feature. alarm@archl-librecm ~]$ sudo perf list List of pre-defined events (to be used in -e or -M): branch-instructions OR branches [Hardware event] branch-misses [Hardware event] bus-cycles [Hardware event] cache-misses [Hardware event] cache-references [Hardware event] cpu-cycles OR cycles [Hardware event] instructions [Hardware event] alignment-faults [Software event] bpf-output [Software event] cgroup-switches [Software event] context-switches OR cs [Software event] cpu-clock [Software event] cpu-migrations OR migrations [Software event] dummy [Software event] emulation-faults [Software event] major-faults [Software event] minor-faults [Software event] page-faults OR faults [Software event] task-clock [Software event] duration_time [Tool event] user_time [Tool event] system_time [Tool event] armv8_cortex_a53: L1-dcache-loads OR armv8_cortex_a53/L1-dcache-loads/ L1-dcache-load-misses OR armv8_cortex_a53/L1-dcache-load-misses/ L1-dcache-prefetch-misses OR armv8_cortex_a53/L1-dcache-prefetch-misses/ L1-icache-loads OR armv8_cortex_a53/L1-icache-loads/ L1-icache-load-misses OR armv8_cortex_a53/L1-icache-load-misses/ dTLB-load-misses OR armv8_cortex_a53/dTLB-load-misses/ iTLB-load-misses OR armv8_cortex_a53/iTLB-load-misses/ branch-loads OR armv8_cortex_a53/branch-loads/ branch-load-misses OR armv8_cortex_a53/branch-load-misses/ node-loads OR armv8_cortex_a53/node-loads/ node-stores OR armv8_cortex_a53/node-stores/ br_immed_retired OR armv8_cortex_a53/br_immed_retired/[Kernel PMU event] br_mis_pred OR armv8_cortex_a53/br_mis_pred/ [Kernel PMU event] br_pred OR armv8_cortex_a53/br_pred/ [Kernel PMU event] bus_access OR armv8_cortex_a53/bus_access/ [Kernel PMU event] bus_cycles OR armv8_cortex_a53/bus_cycles/ [Kernel PMU event] cid_write_retired OR armv8_cortex_a53/cid_write_retired/[Kernel PMU event] cpu_cycles OR armv8_cortex_a53/cpu_cycles/ [Kernel PMU event] exc_return OR armv8_cortex_a53/exc_return/ [Kernel PMU event] > > > > Best regards, > > -- > > Viacheslav Bocharov <adeep@xxxxxxxxx> > > > > _______________________________________________ > > linux-amlogic mailing list > > linux-amlogic@xxxxxxxxxxxxxxxxxxx > > http://lists.infradead.org/mailman/listinfo/linux-amlogic > >
