This is\nseriously wrong. We can read the vendor id by passing the correct\nudevice parameter to the dm_pci_read_config16() API, however there\nis a shortcut by reading the cached vendor id from the PCI device's\nstruct pci_child_platdata.\n\nWhile we are here fixing this bug, apparently the quirk stuff handle\ncodes in nvme_get_info_from_identify() never takes effect since its\nlogic has never been true at all. Remove these codes completely.\n\nSigned-off-by: Bin Meng <bmeng.cn@gmail.com>\n---\n\n drivers/nvme/nvme.c | 24 +++---------------------\n drivers/nvme/nvme.h | 1 -\n 2 files changed, 3 insertions(+), 22 deletions(-)", "diff": "diff --git a/drivers/nvme/nvme.c b/drivers/nvme/nvme.c\nindex 151fe92..2ac0870 100644\n--- a/drivers/nvme/nvme.c\n+++ b/drivers/nvme/nvme.c\n@@ -547,7 +547,6 @@ static int nvme_setup_io_queues(struct nvme_dev *dev)\n \n static int nvme_get_info_from_identify(struct nvme_dev *dev)\n {\n-\tu16 vendor, device;\n \tstruct nvme_id_ctrl buf, *ctrl = &buf;\n \tint ret;\n \tint shift = NVME_CAP_MPSMIN(nvme_readq(&dev->bar->cap)) + 12;\n@@ -585,22 +584,6 @@ static int nvme_get_info_from_identify(struct nvme_dev *dev)\n \t\tdev->max_transfer_shift = 20;\n \t}\n \n-\t/* Apply quirk stuff */\n-\tdm_pci_read_config16(dev->pdev, PCI_VENDOR_ID, &vendor);\n-\tdm_pci_read_config16(dev->pdev, PCI_DEVICE_ID, &device);\n-\tif ((vendor == PCI_VENDOR_ID_INTEL) &&\n-\t (device == 0x0953) && ctrl->vs[3]) {\n-\t\tunsigned int max_transfer_shift;\n-\t\tdev->stripe_size = (ctrl->vs[3] + shift);\n-\t\tmax_transfer_shift = (ctrl->vs[3] + 18);\n-\t\tif (dev->max_transfer_shift) {\n-\t\t\tdev->max_transfer_shift = min(max_transfer_shift,\n-\t\t\t\t\t\t dev->max_transfer_shift);\n-\t\t} else {\n-\t\t\tdev->max_transfer_shift = max_transfer_shift;\n-\t\t}\n-\t}\n-\n \treturn 0;\n }\n \n@@ -629,8 +612,8 @@ static int nvme_blk_probe(struct udevice *udev)\n \tstruct blk_desc *desc = dev_get_uclass_platdata(udev);\n \tstruct nvme_ns *ns = dev_get_priv(udev);\n \tu8 flbas;\n-\tu16 vendor;\n \tstruct nvme_id_ns buf, *id = &buf;\n+\tstruct pci_child_platdata *pplat;\n \n \tmemset(ns, 0, sizeof(*ns));\n \tns->dev = ndev;\n@@ -649,8 +632,8 @@ static int nvme_blk_probe(struct udevice *udev)\n \tdesc->log2blksz = ns->lba_shift;\n \tdesc->blksz = 1 << ns->lba_shift;\n \tdesc->bdev = udev;\n-\tdm_pci_read_config16(ndev->pdev, PCI_VENDOR_ID, &vendor);\n-\tsprintf(desc->vendor, \"0x%.4x\", vendor);\n+\tpplat = dev_get_parent_platdata(udev->parent);\n+\tsprintf(desc->vendor, \"0x%.4x\", pplat->vendor);\n \tmemcpy(desc->product, ndev->serial, sizeof(ndev->serial));\n \tmemcpy(desc->revision, ndev->firmware_rev, sizeof(ndev->firmware_rev));\n \tpart_init(desc);\n@@ -791,7 +774,6 @@ static int nvme_probe(struct udevice *udev)\n \tstruct nvme_dev *ndev = dev_get_priv(udev);\n \tu64 cap;\n \n-\tndev->pdev = pci_get_controller(udev);\n \tndev->instance = trailing_strtol(udev->name);\n \n \tINIT_LIST_HEAD(&ndev->namespaces);\ndiff --git a/drivers/nvme/nvme.h b/drivers/nvme/nvme.h\nindex 267884e..cd411be 100644\n--- a/drivers/nvme/nvme.h\n+++ b/drivers/nvme/nvme.h\n@@ -608,7 +608,6 @@ struct nvme_dev {\n \tstruct list_head node;\n \tstruct nvme_queue **queues;\n \tu32 __iomem *dbs;\n-\tstruct udevice *pdev;\n \tint instance;\n \tunsigned queue_count;\n \tunsigned online_queues;\n", "prefixes": [ "U-Boot", "02/14" ] }
