Add ACS quirks to declare DMA isolation for the following devices: - BGX device found on Octeon-TX (8xxx) - CGX device found on Octeon-TX2 (9xxx) - RPM device found on Octeon-TX3 (10xxx) Link: https://lore.kernel.org/r/20210810122425.1115156-1-george.cherian@marvell.com Signed-off-by: George Cherian Signed-off-by: Bjorn Helgaas Signed-off-by: Sasha Levin --- diff --git a/drivers/pci/quirks.c b/drivers/pci/quirks.c index f2e9594..5d2aceb 100644 --- a/drivers/pci/quirks.c +++ b/drivers/pci/quirks.c @@ -4864,6 +4864,10 @@ static const struct pci_dev_acs_enabled { { 0x10df, 0x720, pci_quirk_mf_endpoint_acs }, /* Emulex Skyhawk-R */ /* Cavium ThunderX */ { PCI_VENDOR_ID_CAVIUM, PCI_ANY_ID, pci_quirk_cavium_acs }, + /* Cavium multi-function devices */ + { PCI_VENDOR_ID_CAVIUM, 0xA026, pci_quirk_mf_endpoint_acs }, + { PCI_VENDOR_ID_CAVIUM, 0xA059, pci_quirk_mf_endpoint_acs }, + { PCI_VENDOR_ID_CAVIUM, 0xA060, pci_quirk_mf_endpoint_acs }, /* APM X-Gene */ { PCI_VENDOR_ID_AMCC, 0xE004, pci_quirk_xgene_acs }, /* Ampere Computing */
