Hi Bjorn, Could you please help to review/ack this patch, based on the following comments from Lorenzo? > apart from patch 1, that requires Bjorn's ACK, I would take the > series (I will rewrite the logs) Thanks, Ray On 6/12/2018 1:30 AM, poza@codeaurora.org wrote: > On 2018-06-12 05:51, Ray Jui wrote: >> Activate PAXC bridge quirk for more PAXC based PCIe root complex with >> the following PCIe device ID: >> 0xd750, 0xd802, 0xd804 >> >> Signed-off-by: Ray Jui <ray.jui@broadcom.com> >> --- >> drivers/pci/quirks.c | 3 +++ >> 1 file changed, 3 insertions(+) >> >> diff --git a/drivers/pci/quirks.c b/drivers/pci/quirks.c >> index 2990ad1..47dfea0 100644 >> --- a/drivers/pci/quirks.c >> +++ b/drivers/pci/quirks.c >> @@ -2195,6 +2195,9 @@ static void quirk_paxc_bridge(struct pci_dev *pdev) >> } >> DECLARE_PCI_FIXUP_EARLY(PCI_VENDOR_ID_BROADCOM, 0x16cd, >> quirk_paxc_bridge); >> DECLARE_PCI_FIXUP_EARLY(PCI_VENDOR_ID_BROADCOM, 0x16f0, >> quirk_paxc_bridge); >> +DECLARE_PCI_FIXUP_EARLY(PCI_VENDOR_ID_BROADCOM, 0xd750, >> quirk_paxc_bridge); >> +DECLARE_PCI_FIXUP_EARLY(PCI_VENDOR_ID_BROADCOM, 0xd802, >> quirk_paxc_bridge); >> +DECLARE_PCI_FIXUP_EARLY(PCI_VENDOR_ID_BROADCOM, 0xd804, >> quirk_paxc_bridge); >> #endif >> >> /* Originally in EDAC sources for i82875P: > > Reviewed-by: Oza Pawandeep <poza@codeaurora.org>

I agree with you. I'll find time to improve this by moving them into the driver's config accessors in the future, after v4.19. >> --- >> drivers/pci/quirks.c | 3 +++ >> 1 file changed, 3 insertions(+) >> >> diff --git a/drivers/pci/quirks.c b/drivers/pci/quirks.c >> index 2990ad1..47dfea0 100644 >> --- a/drivers/pci/quirks.c >> +++ b/drivers/pci/quirks.c >> @@ -2195,6 +2195,9 @@ static void quirk_paxc_bridge(struct pci_dev *pdev) >> } >> DECLARE_PCI_FIXUP_EARLY(PCI_VENDOR_ID_BROADCOM, 0x16cd, quirk_paxc_bridge); >> DECLARE_PCI_FIXUP_EARLY(PCI_VENDOR_ID_BROADCOM, 0x16f0, quirk_paxc_bridge); >> +DECLARE_PCI_FIXUP_EARLY(PCI_VENDOR_ID_BROADCOM, 0xd750, quirk_paxc_bridge); >> +DECLARE_PCI_FIXUP_EARLY(PCI_VENDOR_ID_BROADCOM, 0xd802, quirk_paxc_bridge); >> +DECLARE_PCI_FIXUP_EARLY(PCI_VENDOR_ID_BROADCOM, 0xd804, quirk_paxc_bridge); >> #endif >> >> /* Originally in EDAC sources for i82875P: >> -- >> 2.1.4 >>
