From b13d4b30c3e79ede3e80a018e8204585bbc447dd Mon Sep 17 00:00:00 2001 From: vasilito Date: Wed, 22 Jul 2026 19:28:47 +0900 Subject: [PATCH] =?UTF-8?q?driver-manager:=20v1.9=20=E2=80=94=20QEMU-funct?= =?UTF-8?q?ional=20test=20scripts=20+=20MODALIAS=20+=20Linux=20pci=5Fdevic?= =?UTF-8?q?e=5Fid=20parsing?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Seventh-round integrations of the driver-manager migration's D-phase. This round makes the 6 test scripts actually run QEMU via qemu-login-expect.py, adds a MODALIAS scheme endpoint for operator queries, and ports Linux's pci_device_id parsing so Linux drivers can be loaded with least effort. Test scripts (6, all functional now): - test-driver-manager-parity.sh (C1 dual-mode observation): runs QEMU with redbear-mini live.iso, expects driver-manager and pcid-spawner to both bind the same 17 drivers. Exits 0 on PASS, 1 on FAIL, 0 on SKIP (QEMU not available). - test-driver-manager-active.sh (C3 active): QEMU with driver-manager active, verifies all 17 drivers bind and scheme:driver-params is present. - test-driver-manager-initfs.sh (C2 initfs): QEMU virtio-blkd boot, verifies storage drivers come up before redoxfs mounts. - test-driver-manager-hotplug.sh (D3 hotplug): QEMU with QMP socket, verifies PCIe hotplug detection (sub-200ms latency). - test-driver-manager-pm.sh (D2 runtime PM): QEMU with driver-manager bound drivers, verifies suspend/resume callbacks fire. - test-driver-manager-cutover.sh (C4 production): QEMU 3-reboot bound-set identity check. modalias.rs (NEW): - compute_modalias(info) returns a MODALIAS string in Linux's pci_uevent format (pci:v0000VVVVd0000DDDDsv0000SSSSsd0000UUUUbcCCccSScciiII). - compute_match_modalias(matches) computes per-match MODALIAS for a driver's match_table. linux_loader.rs (NEW): - parse_linux_id_table(path) reads a Linux driver's pci_device_id table from C source and returns a Vec. - parse_linux_id_table_from_source(source) parses from a string. - to_driver_match(id) converts a LinuxPciId to redox_driver_core::r#match::DriverMatch. - Handles named vendor constants (PCI_VENDOR_ID_INTEL, INTEL, AMD, NVIDIA, QCOM, REALTEK, BROADCOM, AQUANTIA, MARVELL, AMPERE, MICROSOFT, SONY, TI, RENESAS, NOVELL, SIS, VIATECH, HYGON). - Linux class field is a packed 3-byte value (base<<16|subclass<<8|prog_if) and is decoded back into separate class/subclass/prog_if fields. scheme.rs: - Added /modalias endpoint. Write MODALIAS string, get back the matching driver name (used by operators for manual driver selection). main.rs: - Declared modalias.rs and linux_loader.rs.
