Hi All:
I added M5OPS pseudo-instructions to a core computing part of my
program code, but I now have a problem with M5OPS_RESETSTATS once I execute
M5OPS_RESETSTATS and then M5OPS_DUMPSTATS. In the dump result, only eight
system.mem_ctrls statistics are printed (32 mem_ctrls are configured). After
the GEM5 simulation, the dump result contains 32 system.mem_ctrls statistics.
If M5OPS_RESETSTATS is not used, the result of multiple dumps is correct.
My gem5 command is :
build/ARM/gem5.fast -d goto_10000_m5out/ccopy2.goto ./configs/soc_base/se.py -n
1 --mem-size=32GB --mem-type=LPDDR5_6400_1x16_BG_BL16 --ruby --cpu-clock=2GHz
--sys-clock=2GHz --ruby-clock=2GHz --num-hha=4 --ruby-mem-channels=32
--cpu-type=O3_ARM_1636
--cmd=/home/l00515693/KSim_LightESL/benchmark/build/ccopy.goto
my gem5 version is v21.0.1.0
Partial Code：
#define M5OPS_RESETSTATS __asm__ __volatile__ ("mov x0, 0; mov x1, 0; .inst
0XFF000110 | (0x40 << 16);" : : : "x0", "x1");
