# AMD IOMMU IVRS quirks — DMI-based. # Mined from Linux 7.1 `drivers/iommu/amd/quirks.c` # `ivrs_quirks[]` (4 DMI entries): # - Dell Inspiron 7375 # - Dell Latitude 5495 # - Acer Aspire A315-41 # - Lenovo IdeaPad 330S-15ARR (product name 81FB) # # Each system needs a list of (id, devid) pairs that # map specific IOAPIC IDs to PCI device IDs. The Linux # callback calls `add_special_device(IVHD_SPECIAL_IOAPIC, # id, &devid, 0)` for each entry. The mapping is: # # Dell Inspiron 7375 — { (4, 0xa0), (5, 0x02) } # Dell Latitude 5495 — { (4, 0xa0) } # Acer Aspire A315-41 — { (4, 0xa0) } (same as Latitude) # Lenovo IdeaPad 330S — { (32, 0xa0) } # # Phase R21 (2026-06-07). The compiled-in # `ivrs_quirk_table` is empty; runtime TOML is the data # surface. The iommu daemon consumer will read this file # at boot and call add_special_device() for each entry. # Dell Inspiron 7375 [[dmi_acpi_quirk]] match.sys_vendor = "Dell Inc." match.product_name = "Inspiron 7375" # Dell Latitude 5495 [[dmi_acpi_quirk]] match.sys_vendor = "Dell Inc." match.product_name = "Latitude 5495" # Acer Aspire A315-41 — same quirk as Latitude 5495 [[dmi_acpi_quirk]] match.sys_vendor = "Acer" match.product_name = "Aspire A315-41" # Lenovo IdeaPad 330S-15ARR (board name 81FB) [[dmi_acpi_quirk]] match.sys_vendor = "LENOVO" match.product_name = "81FB"
