From 53222b906903fd861dc24ebccfa07ee125941313 Mon Sep 17 00:00:00 2001 From: Matthew Wilcox Date: Fri, 20 May 2005 19:15:43 +0100 Subject: [SCSI] sym2 version 2.2.1 sym2 version 2.2.1: - Fix MMIO BAR detection (Thanks to Bob Picco) - Fix odd-sized transfers with a wide bus (Thanks to Larry Stephens) - Write posting fixes (Thanks to Thibaut Varene) - Change one of the GFP_KERNEL allocations back into a GFP_ATOMIC - Make CCB_BA() return a script-endian address - Move range checks and disabling of devices from the queuecommand path to slave_alloc() - Remove a warning in sym_setup_cdb() - Keep a pointer to the scsi_target instead of the scsi_dev in the tcb - Remove a check for the upper layers passing an oversized cmd - Replace CAM_REQ_ constants with the Linux DID_ constants - Replace CAM_DIR_ constants with the Linux DMA_ constants - Inline sym_read_parisc_pdc() on non-parisc systems Signed-off-by: James Bottomley --- drivers/scsi/sym53c8xx_2/sym_hipd.c | 65 ++++++++++++++++++++----------------- 1 file changed, 36 insertions(+), 29 deletions(-) (limited to 'drivers/scsi/sym53c8xx_2/sym_hipd.c') diff --git a/drivers/scsi/sym53c8xx_2/sym_hipd.c b/drivers/scsi/sym53c8xx_2/sym_hipd.c index 50a176b3888..e753ba27dc5 100644 --- a/drivers/scsi/sym53c8xx_2/sym_hipd.c +++ b/drivers/scsi/sym53c8xx_2/sym_hipd.c @@ -97,7 +97,7 @@ static void sym_print_msg(struct sym_ccb *cp, char *label, u_char *msg) static void sym_print_nego_msg(struct sym_hcb *np, int target, char *label, u_char *msg) { struct sym_tcb *tp = &np->target[target]; - dev_info(&tp->sdev->sdev_target->dev, "%s: ", label); + dev_info(&tp->starget->dev, "%s: ", label); sym_show_msg(msg); printf(".\n"); @@ -149,8 +149,10 @@ static char *sym_scsi_bus_mode(int mode) static void sym_chip_reset (struct sym_hcb *np) { OUTB(np, nc_istat, SRST); + INB(np, nc_mbox1); udelay(10); OUTB(np, nc_istat, 0); + INB(np, nc_mbox1); udelay(2000); /* For BUS MODE to settle */ } @@ -216,6 +218,7 @@ int sym_reset_scsi_bus(struct sym_hcb *np, int enab_int) OUTB(np, nc_stest3, TE); OUTB(np, nc_dcntl, (np->rv_dcntl & IRQM)); OUTB(np, nc_scntl1, CRST); + INB(np, nc_mbox1); udelay(200); if (!SYM_SETUP_SCSI_BUS_CHECK) @@ -280,8 +283,10 @@ static void sym_selectclock(struct sym_hcb *np, u_char scntl3) if (!i) printf("%s: the chip cannot lock the frequency\n", sym_name(np)); - } else - udelay((50+10)); + } else { + INB(np, nc_mbox1); + udelay(50+10); + } OUTB(np, nc_stest3, HSC); /* Halt the scsi clock */ OUTB(np, nc_scntl3, scntl3); OUTB(np, nc_stest1, (DBLEN|DBLSEL));/* Select clock multiplier */ @@ -1445,7 +1450,7 @@ static void sym_check_goals(struct sym_hcb *np, struct scsi_target *starget, static int sym_prepare_nego(struct sym_hcb *np, struct sym_ccb *cp, u_char *msgptr) { struct sym_tcb *tp = &np->target[cp->target]; - struct scsi_target *starget = tp->sdev->sdev_target; + struct scsi_target *starget = tp->starget; struct sym_trans *goal = &tp->tgoal; int msglen = 0; int nego; @@ -1690,7 +1695,7 @@ static void sym_flush_comp_queue(struct sym_hcb *np, int cam_status) if (cam_status) sym_set_cam_status(cmd, cam_status); #ifdef SYM_OPT_HANDLE_DEVICE_QUEUEING - if (sym_get_cam_status(cmd) == CAM_REQUEUE_REQ) { + if (sym_get_cam_status(cmd) == DID_SOFT_ERROR) { struct sym_tcb *tp = &np->target[cp->target]; struct sym_lcb *lp = sym_lp(tp, cp->lun); if (lp) { @@ -1791,12 +1796,13 @@ void sym_start_up (struct sym_hcb *np, int reason) /* * Wakeup all pending jobs. */ - sym_flush_busy_queue(np, CAM_SCSI_BUS_RESET); + sym_flush_busy_queue(np, DID_RESET); /* * Init chip. */ OUTB(np, nc_istat, 0x00); /* Remove Reset, abort */ + INB(np, nc_mbox1); udelay(2000); /* The 895 needs time for the bus mode to settle */ OUTB(np, nc_scntl0, np->rv_scntl0 | 0xc0); @@ -1905,6 +1911,7 @@ void sym_start_up (struct sym_hcb *np, int reason) if (np->features & (FE_ULTRA2|FE_ULTRA3)) { OUTONW(np, nc_sien, SBMC); if (reason == 0) { + INB(np, nc_mbox1); mdelay(100); INW(np, nc_sist); } @@ -2074,7 +2081,7 @@ static void sym_settrans(struct sym_hcb *np, int target, u_char opts, u_char ofs static void sym_setwide(struct sym_hcb *np, int target, u_char wide) { struct sym_tcb *tp = &np->target[target]; - struct scsi_target *starget = tp->sdev->sdev_target; + struct scsi_target *starget = tp->starget; if (spi_width(starget) == wide) return; @@ -2102,7 +2109,7 @@ sym_setsync(struct sym_hcb *np, int target, u_char ofs, u_char per, u_char div, u_char fak) { struct sym_tcb *tp = &np->target[target]; - struct scsi_target *starget = tp->sdev->sdev_target; + struct scsi_target *starget = tp->starget; u_char wide = (tp->head.wval & EWS) ?
