-- cgit v1.2.3 From 466544d8898fc87ed6e2e62ac14af7c50ab7a1a4 Mon Sep 17 00:00:00 2001 From: "Moore, Eric Dean" Date: Wed, 14 Sep 2005 18:09:10 -0600 Subject: [SCSI] fusion SAS support (mptsas driver) updates Summary of Changes: * splitting mpt_interrupt per Christophs suggestion about a month ago * rename ScsiCfgData to SpiCfgData structure, then move all the raid related info into new structure called RaidCfgData. 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 --- drivers/message/fusion/mptbase.c | 449 ++++++++++++++++++++++++-------------- drivers/message/fusion/mptbase.h | 28 ++- drivers/message/fusion/mptctl.c | 4 +- drivers/message/fusion/mptfc.c | 2 +- drivers/message/fusion/mptlan.c | 7 +- drivers/message/fusion/mptsas.c | 2 +- drivers/message/fusion/mptscsih.c | 447 +++++++++++++++++++------------------ drivers/message/fusion/mptscsih.h | 8 +- drivers/message/fusion/mptspi.c | 2 +- 9 files changed, 549 insertions(+), 400 deletions(-) (limited to 'drivers/message/fusion') 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!
