enami ef09ae656f Fix or add protection for mutiple inclusion. 1998-02-13 04:19:13 +00:00
cgd 3b207eaf83 add support for an ATAPI attachment for 'sd'.
fix 'cd' driver's NCD_SCSI bogosity (was using testing wrong macro!)
clean up in various ways:
* make common atapi_mode_{sense,select}() functions.
* put ATAPI data structures in more sensible headers, split up by
  device type.
* include headers a bit more carefully.
* pass flags to attachment-specific cd functions, and use them.
* get rid of SCSI bits in scsipi_base.h's scsipi_make_xs(), move
  them into the correct place in scsi_base.c.
* fix minor typo in struct name in scsipiconf.h (which was apparently
  never used except in a #define later in the same file).
* use __attribute__ to force 4-byte alignment for xs command store,
  so that architectures trying to bus_space_write_multi_N() (where
  N > 1) that data to a controller won't lose.
* clean up a few comments in typos, and make a few #defines easier to
  understand/maintain.
* rename cd_link.h to cdvar.h (via repository copy).  This is exactly
  what a 'var' file is supposed to be.

thorpej d2630f4098 Declare the scsipi_xfer's "flags" member to be volatile, to force it
to be reloaded every time it is checked.  This avoids a condition where
it can be cached in a register in such a way that updates to the flags in
an interrupt handler to not be noticed, which in turn causes the process
doing the i/o to sleep forever.  Bug report and suggested fix from
Hiroshi HORIMOTO <horimoto@cs-yuugao.cs.sist.ac.jp>, PR $4460.

thorpej 75e554c27d Implement two macros, scsipi_command() and scsipi_command_direct(), and
use them to hide the structure of the function pointers we jump through
to issue a command.

enami d7d845c3d2 Cosmetic changes to keep coding style consistency in this directory;
- Indent with tab of width 8.
- Use four column to indent continuation line.
- Fold long line if possible.
- Use return (xx) instead of return xx.
- Compare pointer against NULL instead of testing like boolean.
- Delete whitespace at the end of line.
- Delete whitespace in front of function call operator.
- Delete whitespace after cast.
- Dereference a pointer to function explicitly.
- Add an empty line after local variable declaration.
- Use NULL instead of (char *)0.
- Dont use block for single statement.

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.
