From 7b3595df0e064c8d85ddb6836aaa2af3956fb2ba Mon Sep 17 00:00:00 2001 From: Vikas Chaudhary Date: Wed, 6 Oct 2010 22:50:56 -0700 Subject: [PATCH] [SCSI] qla4xxx: update AER support for ISP82XX * Cleanup qla4xxx_pci_mmio_enabled(): don't want to return PCI_ERS_NEED_RESET if firmware hung. IDC will take care of it. * Request irq after initialize_adapter() in qla82xx_error_recovery(). * Return all active commands from qla4xxx_pci_error_detected(). * Cleanup ql4_def.h Signed-off-by: Vikas Chaudhary Signed-off-by: Ravi Anand Reviewed-by: Mike Christie Signed-off-by: James Bottomley --- drivers/scsi/qla4xxx/ql4_def.h | 19 +------------- drivers/scsi/qla4xxx/ql4_os.c | 45 +++++++++++++++++++++------------- 2 files changed, 29 insertions(+), 35 deletions(-) diff --git a/drivers/scsi/qla4xxx/ql4_def.h b/drivers/scsi/qla4xxx/ql4_def.h index f595ab13c2e1..0f3bfc3da5cf 100644 --- a/drivers/scsi/qla4xxx/ql4_def.h +++ b/drivers/scsi/qla4xxx/ql4_def.h @@ -24,6 +24,7 @@ #include #include #include +#include #include #include @@ -36,24 +37,6 @@ #include "ql4_dbg.h" #include "ql4_nx.h" -#if defined(CONFIG_PCIEAER) -#include -#else -/* AER releated */ -static inline int pci_enable_pcie_error_reporting(struct pci_dev *dev) -{ - return -EINVAL; -} -static inline int pci_disable_pcie_error_reporting(struct pci_dev *dev) -{ - return -EINVAL; -} -static inline int pci_cleanup_aer_uncorrect_error_status(struct pci_dev *dev) -{ - return -EINVAL; -} -#endif - #ifndef PCI_DEVICE_ID_QLOGIC_ISP4010 #define PCI_DEVICE_ID_QLOGIC_ISP4010 0x4010 #endif diff --git a/drivers/scsi/qla4xxx/ql4_os.c b/drivers/scsi/qla4xxx/ql4_os.c index 779745f4e59c..4b6cdb68a52a 100644 --- a/drivers/scsi/qla4xxx/ql4_os.c +++ b/drivers/scsi/qla4xxx/ql4_os.c @@ -2252,6 +2252,8 @@ qla4xxx_pci_error_detected(struct pci_dev *pdev, pci_channel_state_t state) qla4xxx_mailbox_premature_completion(ha); qla4xxx_free_irqs(ha); pci_disable_device(pdev); + /* Return back all IOs */ + qla4xxx_abort_active_cmds(ha, DID_RESET << 16); return PCI_ERS_RESULT_NEED_RESET; case pci_channel_io_perm_failure: set_bit(AF_EEH_BUSY, &ha->flags); @@ -2275,17 +2277,13 @@ qla4xxx_pci_mmio_enabled(struct pci_dev *pdev) if (!is_aer_supported(ha)) return PCI_ERS_RESULT_NONE; - if (test_bit(AF_FW_RECOVERY, &ha->flags)) { - ql4_printk(KERN_WARNING, ha, "scsi%ld: %s: firmware hang -- " - "mmio_enabled\n", ha->host_no, __func__); - return PCI_ERS_RESULT_NEED_RESET; - } else - return PCI_ERS_RESULT_RECOVERED; + return PCI_ERS_RESULT_RECOVERED; } -uint32_t qla4_8xxx_error_recovery(struct scsi_qla_host *ha) +static uint32_t qla4_8xxx_error_recovery(struct scsi_qla_host *ha) { uint32_t rval = QLA_ERROR; + uint32_t ret = 0; int fn; struct pci_dev *other_pdev = NULL; @@ -2297,7 +2295,6 @@ uint32_t qla4_8xxx_error_recovery(struct scsi_qla_host *ha) clear_bit(AF_ONLINE, &ha->flags); qla4xxx_mark_all_devices_missing(ha); qla4xxx_process_aen(ha, FLUSH_DDB_CHANGED_AENS); - qla4xxx_abort_active_cmds(ha, DID_RESET << 16); } fn = PCI_FUNC(ha->pdev->devfn); @@ -2360,7 +2357,16 @@ uint32_t qla4_8xxx_error_recovery(struct scsi_qla_host *ha) /* Clear driver state register */ qla4_8xxx_wr_32(ha, QLA82XX_CRB_DRV_STATE, 0); qla4_8xxx_set_drv_active(ha); - ha->isp_ops->enable_intrs(ha); + ret = qla4xxx_request_irqs(ha); + if (ret) { + ql4_printk(KERN_WARNING, ha, "Failed to " + "reserve interrupt %d already in use.\n", + ha->pdev->irq); + rval = QLA_ERROR; + } else { + ha->isp_ops->enable_intrs(ha); + rval = QLA_SUCCESS; + } } qla4_8xxx_idc_unlock(ha); } else { @@ -2372,8 +2378,18 @@ uint32_t qla4_8xxx_error_recovery(struct scsi_qla_host *ha) clear_bit(AF_FW_RECOVERY, &ha->flags); rval = qla4xxx_initialize_adapter(ha, PRESERVE_DDB_LIST); - if (rval == QLA_SUCCESS) - ha->isp_ops->enable_intrs(ha); + if (rval == QLA_SUCCESS) { + ret = qla4xxx_request_irqs(ha); + if (ret) { + ql4_printk(KERN_WARNING, ha, "Failed to" + " reserve interrupt %d already in" + " use.\n", ha->pdev->irq); + rval = QLA_ERROR; + } else { + ha->isp_ops->enable_intrs(ha); + rval = QLA_SUCCESS; + } + } qla4_8xxx_idc_lock(ha); qla4_8xxx_set_drv_active(ha); qla4_8xxx_idc_unlock(ha); @@ -2415,12 +2431,7 @@ qla4xxx_pci_slot_reset(struct pci_dev *pdev) goto exit_slot_reset; } - ret = qla4xxx_request_irqs(ha); - if (ret) { - ql4_printk(KERN_WARNING, ha, "Failed to reserve interrupt %d" - " already in use.\n", pdev->irq); - goto exit_slot_reset; - } + ha->isp_ops->disable_intrs(ha); if (is_qla8022(ha)) { if (qla4_8xxx_error_recovery(ha) == QLA_SUCCESS) { -- 2.39.5
