Hi , I am trying to run dhrystone on riscv. The number of Loops/Runs = 10. Once i start the run, it doesnt get completed. No error was thrown either:
./build/RISCV/gem5.opt ./configs/example/se.py -c ./tests/dhrystone_riscv_u74 gem5 Simulator System. http://gem5.org gem5 is copyrighted software; use the --copyright option for details. gem5 version 21.2.1.0 gem5 compiled Jun 8 2022 04:45:26 gem5 started Jun 8 2022 11:40:40 gem5 executing on eden, pid 496235 command line: ./build/RISCV/gem5.opt ./configs/example/se.py -c ./tests/dhrystone_riscv_u74 Global frequency set at 1000000000000 ticks per second warn: No dot file generated.

Then i tried running with “Exec” debug trace and the following instructions were the last of the executed ones: `4163000: system.cpu: T0 : 0x2a144 @read+14 : c_bnez a5, 32 : IntAlu : ` `4164000: system.cpu: T0 : 0x2a146 @read+16 : addi a7, zero, 63 : IntAlu : D=0x000000000000003f` **`4165000: system.cpu: T0 : 0x2a14a @read+20 : ecall : No_OpClass :`** So then i tried using “All” debug flag and i got the following: `13157165000: read.wrapped_function_event: EventFunctionWrapped 263105 scheduled @ 13157215000` `13157215000: read.wrapped_function_event: EventFunctionWrapped 263105 executed @ 13157215000` `13157215000: system.cpu.[tid:0]: Reading int reg 10 (10) as 0.` `13157215000: system.cpu.[tid:0]: Reading int reg 11 (11) as 0x85f30.` `13157215000: system.cpu.[tid:0]: Reading int reg 12 (12) as 0x2000.` `13157215000: system.cpu: T0 : syscall Retrying read(0, 548656, 8192)...` `13157215000: system.cpu.[tid:0]: Reading int reg 10 (10) as 0.` `13157215000: system.cpu.[tid:0]: Reading int reg 11 (11) as 0x85f30.` `13157215000: system.cpu.[tid:0]: Reading int reg 12 (12) as 0x2000.` **`13157215000: system.cpu: T0 : syscall read still needs retry.`** Any suggestion on how to fix it?
