This patch adds its device ID 0x9125 to the Function 1 DMA alias quirk list. This patch should not be confused with an earlier patch, commit 059983790a4c ("PCI: Add function 1 DMA alias quirk for Marvell 9215 SATA controller"), which applies to a different chip with a similar model number, 88SE9215. 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 Reported-by: sbingner Signed-off-by: Yifeng Li --- drivers/pci/quirks.c | 3 +++ 1 file changed, 3 insertions(+) diff --git a/drivers/pci/quirks.c b/drivers/pci/quirks.c index 003950c73..20a932690 100644 --- a/drivers/pci/quirks.c +++ b/drivers/pci/quirks.c @@ -4103,6 +4103,9 @@ DECLARE_PCI_FIXUP_HEADER(PCI_VENDOR_ID_MARVELL_EXT, 0x9120, 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 */
