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.
cd_scsibus_set_mode, to specifie the real len of "data" we need. These
functions were broken when scsi_cd_write_params_page was added to
scsi_cd_pages, thus changing the len of scsi_cd_mode_data.
The following patch employs a smarter adaptive polling
scheme. It also improves the comments, in particular giving
due credit to Phil Budne for his efforts in nunderstanding
the device. It also relaxes the pattern for auto config so
more devices match.
pseudo-device rnd # /dev/random and in-kernel generator
in config files.
o Add declaration to all architectures.
o Clean up copyright message in rnd.c, rnd.h, and rndpool.c to include
that this code is derived in part from Ted Tyso's linux code.
- dereference a pointer to function explicitly.
- fold long line to fit columns < 80.
- put whitespaces around a binary operator.
- don't put a single statement into a block.
about actual position when reading tape position, you should flush any
pending writes. Well, if the tape is write protected, some drives don't
see the zero count WRITE FILE MARK command as a no-op and complain. Dumb!
- 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.
The method for doing this is to try and use the DATA COMPRESSION mode page
first, followed by the DEVICE CONFIGURATION page (this is because most newer
tape devices are now using DATA COMPRESSION instead of DEVICE CONFIGURATION
pages).
Add in the logical && hardware read position and set position ioctls. Oddly
enough, because NetBSD is limited in having the driver track file && record
numbers, the usual agony over what to do once you use logical or hardware
block positioning can be avoided. Amusing.
Make a minor change so that for SCSIVERBOSE cases that SCSI_SILENT in
the xs' flags is still observed.
(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.
gup to the kernel) more detailed SCSI error printing, based off of final
SCSI-2 specification. This will also print out things like progress indicator
errors, and will also dump out additional sense bytes that haven't been decoded.
Also, turned the error message 'DELAYED' to 'DEFERRED' since that's more
accurate.
is called *after* the driver `done' routine. This fixes disk I/O statistics
on SCSI devices.
Also, calling the `done' routine with a `complete' argument of 0 and actually
having it do anything meaningful loses in at least 3 ways, so just nuke the
argument altogether and don't call it this way. If the driver needs to do
some error handling, that's what `err_handler' is for.
into 8 bits generate (bogus) warnings on some architectures, but the
change to pad on "scsi inquiry" is no longer needed, apparently.
Thanks to Matthias Pfaller for pointing the latter out to me.
- Deal with devices that ignore the length specified in the
inquiry command.
- Allow asynchronous requests without using a buf (key off NOSLEEP instead).
- Implement a simple quirks framework for changers.
- Add a quirk for the Spectra 9000 8mm tape library; it requires a
slightly-longer-than-1-minute delay to take tape inventory. Many
thanks to David Webster at Cygnus Solutions for testing this for me.
host adapter drivers, indicating the highest SCSI target they can
address. Use this value to dynamically allocate data structures, rather
than hard-coding 8 targets.
These changes allow targets > 7 to be addressed on wide SCSI busses.
Fixes PRs #1674 and #2892.
management by itself. But when it gets a start unit request, it keeps
the floppy motor running all the time. This adds code for dealing with
yet another quirk (SDEV_NOSTARTUNIT) that prevents sd.c from sending
start unit requests. A entry for the Teac FC-1 is added to the quirk
table.
