## Summary On pc686 under QEMU with `--console=/dev/com1` (as passed by the `pc-qemu` tester configuration), `ts-validation-io-kernel` and four `ts-fatal-*` tests (`ts-fatal-idle-thread-create-failed`, `ts-fatal-idle-thread-stack-too-small`, `ts-fatal-init-task-construct-failed`, `ts-fatal-too-large-tls-size`) print to VGA instead of COM1, so `rtems-test --rtems-bsp=pc-qemu` sees no test output and reports them as invalid. I see this on main at 5be22160f3 (after !1572 was merged), and I saw it earlier with !1572 and !1573 applied. Before !1572, `ts-validation-io-kernel` was reported as a timeout instead, because `getchark()` blocked. The console and printk ports are selected from the command line in `pc386_parse_console_arguments()`, called from `bsp_start()` (bsps/i386/pc386/start/bspstart.c). Before that, `BSPPrintkPort` keeps its build-time default, which is VGA unless `USE_COM1_AS_CONSOLE` is enabled (bsps/i386/pc386/console/printk_support.c). - `ts-validation-io-kernel` provides its own `boot_card()`, so `bsp_start()` never runs. It also does not store the command line, so `bsp_boot_cmdline` stays NULL. - The `ts-fatal-*` tests above run at `RTEMS_SYSINIT_BSP_EARLY` (0x140), before `RTEMS_SYSINIT_BSP_START` (0x300), the system initialization step that calls `bsp_start()` (bsps/shared/start/bootcard.c). Possible fixes: build the pc-qemu test configuration with `USE_COM1_AS_CONSOLE` (option in spec/build/bsps/i386/pc386/optconcom1.yml), or select the printk port from the command line on first use of `BSP_output_char`. The second would not cover `ts-validation-io-kernel` by itself, because that test's `boot_card()` does not set `bsp_boot_cmdline`. I'd be happy to work on this if one of these approaches is acceptable. ## Steps to reproduce 1. Build main (5be22160f3) for `i386/pc686` with `BUILD_TESTS = True`. 2. Run `rtems-test --rtems-bsp=pc-qemu` on `ts-validation-io-kernel.exe` and the four `ts-fatal-*` tests above: all five are reported as invalid. 3. Rebuild with `USE_COM1_AS_CONSOLE = True` in the `[i386/pc686]` section and run them again: all five print to COM1 and pass. -- View it on GitLab: https://gitlab.rtems.org/rtems/rtos/rtems/-/work_items/5818 You're receiving this email because of your account on gitlab.rtems.org.
