perry 69fbaa747d updates from FreeBSD via Dave Huang <khym@bga.com> 1997-09-23 02:27:43 +00:00
bouyer 6f3bab1f59 Merge scsipi branch in the mainline. This add support for ATAPI devices
(currently only CD-ROM drives on i386). The sys/dev/scsipi system provides 2
busses to which devices can attach (scsibus and atapibus). This needed to
change some include files and structure names in the low level scsi drivers.

bouyer f50739b7b5 Back out previous change. This was for bouyer-scsipi, and not for the trunk. 1997-07-23 10:50:29 +00:00
bouyer 4022e46acf Forgot a scsi->dev/scsipi. 1997-07-23 07:41:56 +00:00
perry 40533e83ff Commit latest fixes/upgrades to NCR SCSI driver. From FreeBSD via
Dave Huang <khym@bga.com>

Tested on alpha by cgd, tested on several i386 boxes. Certainly causes
no harm to the goddamned mess, but the NCR driver only works when you
perform voodoo rituals on it anyway.

This is what Dave said (in email) has been added to the driver:

  ----------------------------------------------------------------------
  This seems to be the most significant change:
  General cleanup and new features for 53c875 based cards, especially the
  Tekram DC390W/U/F, whose config EEPROM can now be dumped, if the kernel
  is built with option NCR_TEKRAM_EEPROM.

  Other changes:

  - add brackets to expansion of OUTB/W/L macro arguments.
  - remove unused NCB structure element ns_async
  - support sync. SCSI offset of 16 (instead of only 8) on 825A and 875
  - correctly identify 53c810A and 53c825A chips
  - preserve SCSI BIOS settings of PCI performance options
  - remove (already disabled) support for NCR reset because of command timeout
  - reverse order of reading of SCSI and DMA specific interrupt cause registers
  - add definition of Tekram config EEPROM contents (not currently used)
  ----------------------------------------------------------------------

perry a797b925b2 Incorporate updated version of fixes from FreeBSD submitted in PR
2841, plus some fixes to make the patches work on the Alpha. Seems to
improve the NCR driver a lot. We probably should try to incorporate
any updates that have happened since, too.

cgd 8d2afa9f27 RCS ID police; get rid of Id keyword. 1996-03-11 23:06:04 +00:00
cgd 046633ffe1 Move INT32, U_INT32, TIMEOUT definitions to ncr_reg.h, and add definitions
for U_INT8, INT16, U_INT16 definitions.  Convert structs and
    definitions in ncr_reg.h (e.g. ncrcmd, the chip register layout, etc.)
    to use these definitions.
Add INB_OFF, INL_OFF, and OUTL_OFF macros to access specified offsets into
    I/O or memory space.  Convert register dumps (etc.), and cache snoop
    test to use these new macros, so that nothing accesses the device
    I/O or memory space directly.  (Register dumps now come from I/O space
    if NCR_IOMAPPED.  They used to bogusly use memory space.)
Add a new relocation type for script entries, RELOC_KVAR.  Allow scripts
    access to mono_time.tv_sec, mono_time, and ncr_cache via this
    mechanism, and convert scripts to use it.  An ncrcmd is only 32 bits
    wide, and KVAs may be > 32 bits wide (e.g. on Alpha), leading to
    linker problems.  This is a safer way to do this anyway; relocation is
    more deterministic this way, and doesn't rely on KVAs not looking like
    other relocation types.
Panic if an unmatched relocation other than 'zero' is specified.  That's
    now a script bug.  (This used to be used to convert KVAs of kernel
    variables referenced in the script to PCI bus physical addresses,
    and that is now handled by RELOC_KVAR relocations.)
Figure out and print the model of chip.
