From 7cfe99a526b92e30df19673b3533f827bbe93821 Mon Sep 17 00:00:00 2001 From: Ed Lin - PTU Date: Mon, 26 Jan 2009 02:41:53 -0800 Subject: [PATCH] [SCSI] stex: Small fixes Some small fixes, including: - add data direction in req_msg because new firmware version may require this (backward compatible) - change internal timeout value - change judgment of type st_vsc1 - blank line handling, etc. Signed-off-by: Ed Lin Signed-off-by: James Bottomley --- drivers/scsi/stex.c | 28 ++++++++++++++++++++++------ 1 file changed, 22 insertions(+), 6 deletions(-) diff --git a/drivers/scsi/stex.c b/drivers/scsi/stex.c index 425a61c79bb6..c1a79c3f4712 100644 --- a/drivers/scsi/stex.c +++ b/drivers/scsi/stex.c @@ -103,7 +103,7 @@ enum { MU_REQ_COUNT = (MU_MAX_REQUEST + 1), MU_STATUS_COUNT = (MU_MAX_REQUEST + 1), - STEX_CDB_LENGTH = MAX_COMMAND_SIZE, + STEX_CDB_LENGTH = 16, REQ_VARIABLE_LEN = 1024, STATUS_VAR_LEN = 128, ST_CAN_QUEUE = MU_MAX_REQUEST, @@ -114,6 +114,9 @@ enum { SG_CF_EOT = 0x80, /* end of table */ SG_CF_64B = 0x40, /* 64 bit item */ SG_CF_HOST = 0x20, /* sg in host memory */ + MSG_DATA_DIR_ND = 0, + MSG_DATA_DIR_IN = 1, + MSG_DATA_DIR_OUT = 2, st_shasta = 0, st_vsc = 1, @@ -123,7 +126,7 @@ enum { PASSTHRU_REQ_TYPE = 0x00000001, PASSTHRU_REQ_NO_WAKEUP = 0x00000100, - ST_INTERNAL_TIMEOUT = 30, + ST_INTERNAL_TIMEOUT = 180, ST_TO_CMD = 0, ST_FROM_CMD = 1, @@ -194,7 +197,7 @@ struct req_msg { u8 target; u8 task_attr; u8 task_manage; - u8 prd_entry; + u8 data_dir; u8 payload_sz; /* payload size in 4-byte, not used */ u8 cdb[STEX_CDB_LENGTH]; u8 variable[REQ_VARIABLE_LEN]; @@ -318,8 +321,8 @@ MODULE_VERSION(ST_DRIVER_VERSION); static void stex_gettime(__le32 *time) { struct timeval tv; - do_gettimeofday(&tv); + do_gettimeofday(&tv); *time = cpu_to_le32(tv.tv_sec & 0xffffffff); *(time + 1) = cpu_to_le32((tv.tv_sec >> 16) >> 16); } @@ -340,7 +343,7 @@ static void stex_invalid_field(struct scsi_cmnd *cmd, { cmd->result = (DRIVER_SENSE << 24) | SAM_STAT_CHECK_CONDITION; - /* "Invalid field in cbd" */ + /* "Invalid field in cdb" */ scsi_build_sense_buffer(0, cmd->sense_buffer, ILLEGAL_REQUEST, 0x24, 0x0); done(cmd); @@ -469,6 +472,7 @@ stex_queuecommand(struct scsi_cmnd *cmd, void (* done)(struct scsi_cmnd *)) unsigned int id,lun; struct req_msg *req; u16 tag; + host = cmd->device->host; id = cmd->device->id; lun = cmd->device->lun; @@ -480,6 +484,7 @@ stex_queuecommand(struct scsi_cmnd *cmd, void (* done)(struct scsi_cmnd *)) static char ms10_caching_page[12] = { 0, 0x12, 0, 0, 0, 0, 0, 0, 0x8, 0xa, 0x4, 0 }; unsigned char page; + page = cmd->cmnd[2] & 0x3f; if (page == 0x8 || page == 0x3f) { scsi_sg_copy_from_buffer(cmd, ms10_caching_page, @@ -523,6 +528,7 @@ stex_queuecommand(struct scsi_cmnd *cmd, void (* done)(struct scsi_cmnd *)) if (cmd->cmnd[1] == PASSTHRU_GET_DRVVER) { struct st_drvver ver; size_t cp_len = sizeof(ver); + ver.major = ST_VER_MAJOR; ver.minor = ST_VER_MINOR; ver.oem = ST_OEM; @@ -556,6 +562,13 @@ stex_queuecommand(struct scsi_cmnd *cmd, void (* done)(struct scsi_cmnd *)) /* cdb */ memcpy(req->cdb, cmd->cmnd, STEX_CDB_LENGTH); + if (cmd->sc_data_direction == DMA_FROM_DEVICE) + req->data_dir = MSG_DATA_DIR_IN; + else if (cmd->sc_data_direction == DMA_TO_DEVICE) + req->data_dir = MSG_DATA_DIR_OUT; + else + req->data_dir = MSG_DATA_DIR_ND; + hba->ccb[tag].cmd = cmd; hba->ccb[tag].sense_bufflen = SCSI_SENSE_BUFFERSIZE; hba->ccb[tag].sense_buffer = cmd->sense_buffer; @@ -614,6 +627,7 @@ static void stex_copy_data(struct st_ccb *ccb, struct status_msg *resp, unsigned int variable) { size_t count = variable; + if (resp->scsi_status != SAM_STAT_GOOD) { if (ccb->sense_buffer != NULL) memcpy(ccb->sense_buffer, resp->variable, @@ -938,6 +952,7 @@ static int stex_reset(struct scsi_cmnd *cmd) struct st_hba *hba; unsigned long flags; unsigned long before; + hba = (struct st_hba *) &cmd->device->host->hostdata[0]; printk(KERN_INFO DRV_NAME @@ -1022,6 +1037,7 @@ static struct scsi_host_template driver_template = { static int stex_set_dma_mask(struct pci_dev * pdev) { int ret; + if (!pci_set_dma_mask(pdev, DMA_64BIT_MASK) && !pci_set_consistent_dma_mask(pdev, DMA_64BIT_MASK)) return 0; @@ -1079,7 +1095,7 @@ stex_probe(struct pci_dev *pdev, const struct pci_device_id *id) } hba->cardtype = (unsigned int) id->driver_data; - if (hba->cardtype == st_vsc && (pdev->subsystem_device & 0xf) == 0x1) + if (hba->cardtype == st_vsc && (pdev->subsystem_device & 1)) hba->cardtype = st_vsc1; hba->dma_size = (hba->cardtype == st_vsc1 || hba->cardtype == st_seq) ?
