Foundational data-driven hardware-quirk system with all entries through Phase R5. Source of truth: Linux 7.1 DECLARE_PCI_FIXUP_* and PCI_DEV_FLAGS_* conventions. Targets AMD64 bare metal, QEMU, and modern peripherals. Code (redox-driver-sys/src/quirks/): - PciQuirkFlags: 46 bits used (0-45), 18 reserved - UsbQuirkFlags + XhciControllerQuirkFlags tables - PciConfigWriter trait + QuirkAction enum (7 variants) - 14 named callbacks (intel_no_aspm_l0s, amd_ide_class_fix, ht_enable_msi_mapping, p64h2_1k_io, intel_ntb_bar_fix, 7 DMA-alias callbacks, amd_fe_gate_ordering, amd_8131_mmrbc) - lookup_pci_quirks_full, lookup_pci_quirks, lookup_usb_quirks, lookup_xhci_controller_quirks, lookup_dmi_rules - find_standard_capability for PCI cap walks - TOML loader with [[pci_quirk]] / [[usb_quirk]] / [[dmi_rule]] sections - 75 tests pass (mod.rs + toml_loader + dmi + others) Phase R5 adds (2026-06-07): - 10 new flag bits (36-45): BROKEN_INTX_MASKING, NO_PME, PCI_PROBLEM_*, PCI_AGP_FAIL, BUS_NO_MMRBC - 2 new callbacks: cb_amd_fe_gate_ordering (AMD-762 two-register write), cb_amd_8131_mmrbc (rev-gated < 0x12, sets BUS_NO_MMRBC) - Inline ClearBit/SetBit actions for Mellanox, Cyrix, Intel, VIA - 18 new Phase R5 tests (10 mod.rs + 8 toml_loader) TOML (10 files, 244 entries in 07-pci-final-quirks.toml total): 00-core.toml (41) 05-pcie-quirks.toml (52) 06-pci-header-quirks.toml (37) 07-pci-final-quirks.toml (64) — R5 DECLARE_PCI_FIXUP_FINAL 10-gpu.toml (33) 15-audio.toml (7) Verified: 38 distinct flag names used, 46 defined, 0 undefined references.

# New PCIe quirk entries introduced in Phase R2 (2026-06-07).

# Source: Linux 7.1 drivers/pci/quirks.c + include/linux/pci.h

# Flag bit map (see PciQuirkFlags in redox-driver-sys):

# bit 22: NO_FLR (no-resource-reloc root ports)

# bit 23: NO_EXT_TAGS
|
|
# bit 24: NO_RELAXED_ORDERING

# NO_FLR entries (9 device IDs) live in 00-core.toml.

# NO_RELAXED_ORDERING — disables PCIe Relaxed Ordering on Root Port
|
|
# Linux: quirk_relaxedordering_disable (drivers/pci/quirks.c)
|
|
# Reason: Intel Broadwell/Haswell PCIe root ports have a Flow Control
|
|
# Credit erratum that causes Completion TLPs to be lost when Relaxed
|
|
# Ordering is enabled on downstream devices. The quirk sets the flag
|
|
# on the root port; pci_configure_relaxed_ordering() then walks the
|
|
# bus and clears PCI_EXP_DEVCTL_RELAX_EN (0x0010) on each endpoint.
|
|
# Class: PCI_CLASS_NOT_DEFINED (0x000000), class_mask 0xFF0000
