From 97eab63490452f0a5242fa94ddaa9b727d69cb25 Mon Sep 17 00:00:00 2001 From: James Smart Date: Mon, 7 Apr 2008 10:16:05 -0400 Subject: [SCSI] lpfc 8.2.6 : Miscellaneous Fixes Miscellaneous Fixes - Allow WRITE_VPARAM command when the virtual port is in a stopped state - Fixed handling of our queue depth max that was unconditionally raising the depth on all vports, rather than just the vport affected. - Fix race in interrupt handler for mailbox processing that did not take out the host lock. - Removed unused functions: find_node, findnode_rpi, and fabric_abort_flogi - Correct misspelled word unsolicited in message 0146 - Correct HW-error 5 handling - it should not reset the adapter - Correct handling of IOCBs, which did not null out our pCmd field before invoking the midlayer io done function. - Changed our maximum supported target id to 4096 Signed-off-by: James Smart Signed-off-by: James Bottomley --- drivers/scsi/lpfc/lpfc_sli.c | 20 +++++++++----------- 1 file changed, 9 insertions(+), 11 deletions(-) (limited to 'drivers/scsi/lpfc/lpfc_sli.c') diff --git a/drivers/scsi/lpfc/lpfc_sli.c b/drivers/scsi/lpfc/lpfc_sli.c index 741e94af479..70a0a9eab21 100644 --- a/drivers/scsi/lpfc/lpfc_sli.c +++ b/drivers/scsi/lpfc/lpfc_sli.c @@ -3481,26 +3481,21 @@ lpfc_sli_hba_down(struct lpfc_hba *phba) phba->pport->work_port_events &= ~WORKER_MBOX_TMO; spin_unlock(&phba->pport->work_port_lock); + /* Return any pending or completed mbox cmds */ + list_splice_init(&phba->sli.mboxq, &completions); if (psli->mbox_active) { list_add_tail(&psli->mbox_active->list, &completions); psli->mbox_active = NULL; psli->sli_flag &= ~LPFC_SLI_MBOX_ACTIVE; } - - /* Return any pending or completed mbox cmds */ - list_splice_init(&phba->sli.mboxq, &completions); list_splice_init(&phba->sli.mboxq_cmpl, &completions); - INIT_LIST_HEAD(&psli->mboxq); - INIT_LIST_HEAD(&psli->mboxq_cmpl); - spin_unlock_irqrestore(&phba->hbalock, flags); while (!list_empty(&completions)) { list_remove_head(&completions, pmb, LPFC_MBOXQ_t, list); pmb->mb.mbxStatus = MBX_NOT_FINISHED; - if (pmb->mbox_cmpl) { + if (pmb->mbox_cmpl) pmb->mbox_cmpl(phba,pmb); - } } return 1; } @@ -4201,6 +4196,7 @@ lpfc_intr_handler(int irq, void *dev_id) phba->pport->stopped = 1; } + spin_lock(&phba->hbalock); if ((work_ha_copy & HA_MBATT) && (phba->sli.mbox_active)) { pmb = phba->sli.mbox_active; @@ -4211,6 +4207,7 @@ lpfc_intr_handler(int irq, void *dev_id) /* First check out the status word */ lpfc_sli_pcimem_bcopy(mbox, pmbox, sizeof(uint32_t)); if (pmbox->mbxOwner != OWN_HOST) { + spin_unlock(&phba->hbalock); /* * Stray Mailbox Interrupt, mbxCommand * mbxStatus @@ -4226,10 +4223,10 @@ lpfc_intr_handler(int irq, void *dev_id) /* clear mailbox attention bit */ work_ha_copy &= ~HA_MBATT; } else { + phba->sli.mbox_active = NULL; + spin_unlock(&phba->hbalock); phba->last_completion_time = jiffies; del_timer(&phba->sli.mbox_tmo); - - phba->sli.mbox_active = NULL; if (pmb->mbox_cmpl) { lpfc_sli_pcimem_bcopy(mbox, pmbox, MAILBOX_CMD_SIZE); @@ -4282,7 +4279,8 @@ lpfc_intr_handler(int irq, void *dev_id) spin_unlock(&phba->pport->work_port_lock); lpfc_mbox_cmpl_put(phba, pmb); } - } + } else + spin_unlock(&phba->hbalock); if ((work_ha_copy & HA_MBATT) && (phba->sli.mbox_active == NULL)) { send_current_mbox: -- cgit v1.2.3
