Stopped the RISC-V install pulling a desktop media stack (#789)

2026-10-02T14:26:18Z

The RISC-V job installs qemu-system-misc, ninja-build and cmake under a two-minute per-attempt budget. With recommends enabled that install fetches 67 packages and 87 MB of archives, 388 MB unpacked, because qemu-system-misc recommends gstreamer, pulseaudio, v4l and a set of codec libraries. Twenty-six of the 67 are that media stack, and the job runs qemu-system-riscv64 headless. On a slow mirror the download does not finish inside the budget, and all three attempts time out. The install now passes --no-install-recommends. Raising the budget was the alternative and is not available: TIMEOUT_LONG is already sized so that three attempts fit inside the ten-minute install step, as its own comment records. Observed on the run for #783, where all three attempts timed out while a second RISC-V run at the same minute succeeded, which is the mirror-speed dependence this removes.

Gave install_riscv.sh the network hardening install.sh already had, and shared it between them (#721)

2026-09-10T13:28:44Z

install.sh grew a retry loop, per-command timeouts and a deliberately non-gating apt-get update after this runner pool cost several whole runs: a mirror going silent for two hours, and a Hash Sum mismatch from a third-party repository the project does not even use turning builds red. Those lessons were local to that one file. install_riscv.sh had none of them, and #717 puts it on every pull request's critical path. Under set -e its bare apt-get update was a single point of failure for the whole suite -- the precise case install.sh downgrades to a warning on purpose -- and its two wget calls, each fetching about 500 MB, had no retry and no timeout. Rather than copy the helpers and let them drift again, they move to tx_ci_common.sh and both scripts source it, following the arrangement scripts/tx_windows_common.ps1 already uses on the Windows side. install.sh keeps its behaviour exactly: same APT_OPTIONS, same 120-second TIMEOUT, same three-attempt retry, and the comments explaining each of them travel with the code they explain. Two things are new: - TIMEOUT_LONG, 180 seconds, for a single large download. Sized against the 39 seconds each tarball took on 10 Sep 2026 and deliberately not larger: the install step is capped at ten minutes, and a per-attempt timeout able to swallow that cap would leave the retry loop no turn to take, which is the failure mode the apt comment already records. - fetch(), which verifies a SHA-256 before anything is unpacked. Both digests were taken from the releases API and then checked against the bytes the CDN actually serves. This is not an independent trust root -- expected value and file come from the same host -- but it pins the bytes, so a deleted and re-pushed tag or a replaced asset stops the build instead of being picked up silently. Also verifies qemu-system-riscv32 alongside riscv64. run.sh selects one per architecture, so both are worth failing on here rather than at the first test. Verified locally: retry returns 0 on success and 1 after three attempts; fetch accepts a correct digest and, on a wrong one, fails and removes the partial file; the source line resolves from the repository root, from an absolute path and through a symlink; and both recorded digests match the bytes served for the pinned tag.

Added copyright headers to files missing them

2026-06-06T19:48:06Z

Applied the standard MIT license header to all project-owned C, header, assembly, shell, and Python files that were missing a copyright notice. Third-party, toolchain startup, and auto-generated files were excluded. Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

Add QEMU based CI regression test infra for RV32 and RV64 (#526)

2026-05-19T15:03:23Z

Added a QEMU virt-machine BSP and CTest infrastructure to run the ThreadX regression suite on both RISC-V 32-bit and 64-bit targets in CI. New components: - BSP (entry, trap, PLIC, CLINT timer, UART, linker script) targeting QEMU virt machine for RV32 and RV64 - CMake build system with Ninja, supporting multiple build configs - CI scripts: install_riscv.sh (toolchain + QEMU), build_tx_riscv.sh, test_tx_riscv.sh - GitHub Actions workflow job for RISC-V regression gating Port fixes: - RV32 tx_thread_context_restore.S: set MPIE alongside MPP (0x1800 → 0x1880) so mret re-enables interrupts - RV32/RV64 tx_port.h: add TX_REGRESSION_TEST extension macros needed by the test harness - RV32/RV64 example_build scripts: add compile and QEMU launch steps Regression test portability fixes: - Block memory tests: increase pool sizes (320 → 340) to accommodate larger RISC-V block-header alignment - Byte memory test: replace hardcoded offsets with BYTE_POOL_OVERHEAD macro for portable pool-size computation - Event flag timeout test: make counter tolerance unconditional, removing linux-only guard Signed-off-by: Akif Ejaz
