Create assembly file `hello.s`: -```as -.section .text -.globl _start -_start: csrr t0, mhartid - bnez t0, _start - li t0, 0x100000 - li t1, 0x5555 - sw t1, 0(t0) -halt: j halt -``` -2. Create linker script `link.ld`: -```ld -OUTPUT_ARCH( "riscv" ) -ENTRY(_start) -SECTIONS -{ - . = 0x80000000; -} -``` -3. Create runner script `./run.sh` (don't forget to `chmod +x`) -```sh -#!/usr/bin/env bash -timeout 10 qemu-system-riscv64 -M virt -display none -serial stdio -bios none -kernel hello -``` -4. Compile into executable: -```sh -riscv64-unknown-elf-gcc -c -mcmodel=medany -fvisibility=hidden -nostartfiles -march=rv64g -mabi=lp64 -o hello.o hello.s -riscv64-unknown-elf-ld hello.o -nostdlib -T link.ld -o hello -``` -5. Dot-source the script - it will immediately exit cleanly -6. Execute the script - it will timeout with exit code 124 -7. Execute the script with redirected stdin, e.g. `./run.sh < ./run.sh` or `echo | ./run.sh` - it will immediately exit cleanly -Additional information: -This issue happens only with `-serial stdio`. Using `chardev:file` or `chardev:null` does not reproduce the issue. Process substitution like `<(echo 'test')` does not seem to work. `cat | ./run.sh` will wait until any line is send, then exit cleanly. This is mainly an issue when using helper test scripts which want to interact with user, as proper CI/UT would redirect serial anyways. - -I have noticed similar behavior with other RISC-V UART device - when running from scripts, there is no output, as if QEMU was waiting for something, even if there is only UART TX, not RX. It does not matter if I actually type in anything or not. |
