The controller design is quite similar to v2 hw in hip07. However key differences include: -All v2 hw bugs are fixed (hopefully), so workarounds are not required -support for device deregistration -some interrupt modifications -configurable max device support Not yet supported: - controller reset Signed-off-by: John Garry Signed-off-by: Xiang Chen --- drivers/scsi/hisi_sas/Makefile | 1 + drivers/scsi/hisi_sas/hisi_sas_v3_hw.c | 57 ++++++++++++++++++++++++++++++++++ 2 files changed, 58 insertions(+) create mode 100644 drivers/scsi/hisi_sas/hisi_sas_v3_hw.c diff --git a/drivers/scsi/hisi_sas/Makefile b/drivers/scsi/hisi_sas/Makefile index 3a036a8..54774a4 100644 --- a/drivers/scsi/hisi_sas/Makefile +++ b/drivers/scsi/hisi_sas/Makefile @@ -1,3 +1,4 @@ obj-$(CONFIG_SCSI_HISI_SAS) += hisi_sas_main.o obj-$(CONFIG_SCSI_HISI_SAS) += hisi_sas_v1_hw.o hisi_sas_v2_hw.o obj-$(CONFIG_SCSI_HISI_SAS_PCI) += hisi_sas_pci_init.o +obj-$(CONFIG_SCSI_HISI_SAS_PCI) += hisi_sas_v3_hw.o diff --git a/drivers/scsi/hisi_sas/hisi_sas_v3_hw.c b/drivers/scsi/hisi_sas/hisi_sas_v3_hw.c new file mode 100644 index 0000000..80707f6 --- /dev/null +++ b/drivers/scsi/hisi_sas/hisi_sas_v3_hw.c @@ -0,0 +1,57 @@ +/* + * Copyright (c) 2017 Hisilicon Limited. + * + * This program is free software; you can redistribute it and/or modify + * it under the terms of the GNU General Public License as published by + * the Free Software Foundation; either version 2 of the License, or + * (at your option) any later version. + * + */ + +#include "hisi_sas.h" +#define DRV_NAME "hisi_sas_v3_hw" + +static const struct hisi_sas_hw hisi_sas_v3_hw = { +}; + +enum { + /* instances of the controller */ + hip08, +}; + +static const struct hisi_sas_pci_hw hisi_sas_pci_hw_info[] = { + [hip08] = {8, 16, &hisi_sas_v3_hw}, +}; + +static const struct pci_device_id sas_v3_pci_table[] = { + { PCI_VDEVICE(HUAWEI, 0xa230), hip08}, + {} +}; + +static int +hisi_sas_v3_probe(struct pci_dev *pdev, const struct pci_device_id *ent) +{ + const struct hisi_sas_pci_hw *hw; + + hw = &hisi_sas_pci_hw_info[ent->driver_data]; + return hisi_sas_pci_probe(pdev, hw); +} + +static void hisi_sas_v3_remove(struct pci_dev *pdev) +{ + hisi_sas_pci_remove(pdev); +} + +static struct pci_driver sas_v3_pci_driver = { + .name = DRV_NAME, + .id_table = sas_v3_pci_table, + .probe = hisi_sas_v3_probe, + .remove = hisi_sas_v3_remove, +}; + +module_pci_driver(sas_v3_pci_driver); + +MODULE_LICENSE("GPL"); +MODULE_AUTHOR("John Garry "); +MODULE_DESCRIPTION("HISILICON SAS controller v3 hw driver"); +MODULE_ALIAS("platform:" DRV_NAME); -- 1.9.1
