Like other SATA controller chips in the Marvell 88SE91xx series, the Marvell 88SE9125 has the same DMA requester ID hardware bug that prevents it from working under IOMMU. Add it to the list of devices that need the quirk. Without this patch, device initialization fails with DMA errors: ata8: softreset failed (1st FIS failed) DMAR: DRHD: handling fault status reg 2 DMAR: [DMA Write NO_PASID] Request device [03:00.1] fault addr 0xfffc0000 [fault reason 0x02] Present bit in context entry is clear DMAR: DRHD: handling fault status reg 2 DMAR: [DMA Read NO_PASID] Request device [03:00.1] fault addr 0xfffc0000 [fault reason 0x02] Present bit in context entry is clear After applying the patch, the controller can be successfully initialized: ata8: SATA link up 1.5 Gbps (SStatus 113 SControl 330) ata8.00: ATAPI: PIONEER BD-RW BDR-207M, 1.21, max UDMA/100 ata8.00: configured for UDMA/100 scsi 7:0:0:0: CD-ROM PIONEER BD-RW BDR-207M 1.21 PQ: 0 ANSI: 5 Link: https://lore.kernel.org/r/YahpKVR+McJVDdkD@work Reported-by: Sam Bingner Tested-by: Sam Bingner Tested-by: Yifeng Li Signed-off-by: Yifeng Li Signed-off-by: Bjorn Helgaas Reviewed-by: Krzysztof Wilczyński Cc: stable@vger.kernel.org Signed-off-by: Greg Kroah-Hartman --- drivers/pci/quirks.c | 3 +++ 1 file changed, 3 insertions(+) --- a/drivers/pci/quirks.c +++ b/drivers/pci/quirks.c @@ -4004,6 +4004,9 @@ DECLARE_PCI_FIXUP_HEADER(PCI_VENDOR_ID_M quirk_dma_func1_alias); DECLARE_PCI_FIXUP_HEADER(PCI_VENDOR_ID_MARVELL_EXT, 0x9123, quirk_dma_func1_alias); +/* https://bugzilla.kernel.org/show_bug.cgi?id=42679#c136 */ +DECLARE_PCI_FIXUP_HEADER(PCI_VENDOR_ID_MARVELL_EXT, 0x9125, + quirk_dma_func1_alias); DECLARE_PCI_FIXUP_HEADER(PCI_VENDOR_ID_MARVELL_EXT, 0x9128, quirk_dma_func1_alias); /* https://bugzilla.kernel.org/show_bug.cgi?id=42679#c14 */
