This is done because SAS supports RAID, as well as SPI, so the raid stuff should be seperate. * incorrect timeout calculation for cntdn inside WaitForDoorbellAck and WaitForDoortbellInt * add support for interpreting SAS Log Info * Increase Event Log Size from 0xA to 0x32 * Fix bug in mptsas/mptfc/mptspi - when controller has Initiator Mode Disabled, and only running in TargetMode, the mptctl would panic when loading. The fix is to return 0, instead of -ENODEV, in SCSI LLD respective probe routines * Fix bug in mptlan.c - driver will panic if there is host reset, due to dev being set to zero in mpt_lan_ioc_reset * Fix's for SPI - Echo Buffer * Several fix's in mptscsih_io_done - FCP Response info, RESIDUAL_MISMATCH, Data Underrun, etc. * Cleanup Error Handling - EH handlers, mptscsih_flush_cmds, and zeroing out ScsiLookup from mptscsih_qcmd * Cleanup asyn event handling from mptscsih -> mptscsih_event_process. Also added support for SAS Persistent Table Full, an asyn event Signed-off-by: Eric Moore Signed-off-by: James Bottomley --- diff --git a/drivers/message/fusion/mptbase.c b/drivers/message/fusion/mptbase.c index 14d62d96ca41..790a2932ded9 100644 --- a/drivers/message/fusion/mptbase.c +++ b/drivers/message/fusion/mptbase.c @@ -135,7 +135,6 @@ static void mpt_adapter_dispose(MPT_ADAPTER *ioc); static void MptDisplayIocCapabilities(MPT_ADAPTER *ioc); static int MakeIocReady(MPT_ADAPTER *ioc, int force, int sleepFlag); -//static u32 mpt_GetIocState(MPT_ADAPTER *ioc, int cooked); static int GetIocFacts(MPT_ADAPTER *ioc, int sleepFlag, int reason); static int GetPortFacts(MPT_ADAPTER *ioc, int portnum, int sleepFlag); static int SendIocInit(MPT_ADAPTER *ioc, int sleepFlag); @@ -178,6 +177,7 @@ static int ProcessEventNotification(MPT_ADAPTER *ioc, EventNotificationReply_t * static void mpt_sp_ioc_info(MPT_ADAPTER *ioc, u32 ioc_status, MPT_FRAME_HDR *mf); static void mpt_fc_log_info(MPT_ADAPTER *ioc, u32 log_info); static void mpt_sp_log_info(MPT_ADAPTER *ioc, u32 log_info); +static void mpt_sas_log_info(MPT_ADAPTER *ioc, u32 log_info); /* module entry point */ static int __init fusion_init (void); @@ -209,6 +209,144 @@ pci_enable_io_access(struct pci_dev *pdev) pci_write_config_word(pdev, PCI_COMMAND, command_reg); } +/* + * Process turbo (context) reply... + */ +static void +mpt_turbo_reply(MPT_ADAPTER *ioc, u32 pa) +{ + MPT_FRAME_HDR *mf = NULL; + MPT_FRAME_HDR *mr = NULL; + int req_idx = 0; + int cb_idx; + + dmfprintk((MYIOC_s_INFO_FMT "Got TURBO reply req_idx=%08x\n", + ioc->name, pa)); + + switch (pa >> MPI_CONTEXT_REPLY_TYPE_SHIFT) { + case MPI_CONTEXT_REPLY_TYPE_SCSI_INIT: + req_idx = pa & 0x0000FFFF; + cb_idx = (pa & 0x00FF0000) >> 16; + mf = MPT_INDEX_2_MFPTR(ioc, req_idx); + break; + case MPI_CONTEXT_REPLY_TYPE_LAN: + cb_idx = mpt_lan_index; + /* + * Blind set of mf to NULL here was fatal + * after lan_reply says "freeme" + * Fix sort of combined with an optimization here; + * added explicit check for case where lan_reply + * was just returning 1 and doing nothing else. + * For this case skip the callback, but set up + * proper mf value first here:-) + */ + if ((pa & 0x58000000) == 0x58000000) { + req_idx = pa & 0x0000FFFF; + mf = MPT_INDEX_2_MFPTR(ioc, req_idx); + mpt_free_msg_frame(ioc, mf); + mb(); + return; + break; + } + mr = (MPT_FRAME_HDR *) CAST_U32_TO_PTR(pa); + break; + case MPI_CONTEXT_REPLY_TYPE_SCSI_TARGET: + cb_idx = mpt_stm_index; + mr = (MPT_FRAME_HDR *) CAST_U32_TO_PTR(pa); + break; + default: + cb_idx = 0; + BUG(); + } + + /* Check for (valid) IO callback! */ + if (cb_idx < 1 || cb_idx >= MPT_MAX_PROTOCOL_DRIVERS || + MptCallbacks[cb_idx] == NULL) { + printk(MYIOC_s_WARN_FMT "%s: Invalid cb_idx (%d)!\n", + __FUNCTION__, ioc->name, cb_idx); + goto out; + } + + if (MptCallbacks[cb_idx](ioc, mf, mr)) + mpt_free_msg_frame(ioc, mf); + out: + mb(); +} + +static void +mpt_reply(MPT_ADAPTER *ioc, u32 pa) +{ + MPT_FRAME_HDR *mf; + MPT_FRAME_HDR *mr; + int req_idx; + int cb_idx; + int freeme; + + u32 reply_dma_low; + u16 ioc_stat; + + /* non-TURBO reply!
