be probed several times. This fixes the "ATAPI CD probed as wd drive" problem.
Thanks to Geoff Wing <mason@primenet.com.au> for testing this on his hardware.
I also made inclusion of LPRINTF() dependent solely on the symbol
LPTDEBUG, initialized lptdebug variable to 0 instead of 1, and
matched arguments to format strings in LPRINTF() calls.
looking what's the autoconfig do on strange harware, and ATAPI_DEBUG2 is
for debuging data transfers (and is really verbose once the machine has booted
from an IDE disk).
(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.
at the same time instead by using two different calls. This enables
it to check more easily if the combined mode is all right.
- Improve the error checking in audio.c.
- Add a new audio property, AUDIO_PROP_INDEPENDENT, show if the
play and record settings are independent.
- Fix some buglets in audio.c.
-put all early console / KGDB initialization into 1 exported function
(com_*_attach()) each, dont use global variables anymore
-use the passed tcflag_t for port settings instead of hardwiring 8N1
-at autoconfiguration attach time, decide if the attaching device is
already console / KGDB by comparing bus tag and base addr (cgd's wish)
-export a function "com_is_console()" for use by driver frontends for
this comparision
-delay setting of cn_tab->cn_dev until autoconfiguration attach
to get the minor number right
-delete unused comcnprobe() and comcninit()
-Separate KGDB port initialization and softc related stuff to allow
KGDB to be attached in early system startup, before autoconfiguration.
-Export the variables needed by md code to hand-craft bus tag/handle.
-Fix initialization to enable interrupt by line break.
-Call DDB/KGDB at line break (move DDB call from the softirq handler
to the hard handler because it should work without a tty attached too).
a command to the 82586 for every frame to be transmitted. Instead, a
single command sets off the execution of a chain of commands consisting
of alternate XMITs and NO-OPs, where the link fields in the NO-OPs are
set to loop back onto themselves until the next XMIT is ready to go.
This trick found on a Linux WEB page.
All this induces reasonable transmission performance in my old multibus
adapter. The receiver performance is still abysmal..
- Change the way attach and open works to allow multiple audio
devices.
- Split the mulaw.c file into two to avoid dragging in mulaw
convertsion when they are not needed. Add 16 bit alaw/mulaw tables.
- Change the way audio properties are gotten.
- Recognize more versions os SoundBlaster.
- It is now possible to handle devices that want "looping" DMA,
e.g. the SoundBlaster correctly. The WSS and SB drivers use this.
To do this several new methods were introduced in audio_hw_if.
- Different silence handling (forced by previous change).
- The audio driver can now be mmap()-ed, but due to problems in
the VM system only for writing for now.
- The OSS (Linux) audio emulation takes advantage of some of the
new features.
zero. We use this later when the COMPLETE message comes in to set the
final residual count to zero. The flag is reset if the target resumes
a data phase. This obsoletes the `AUTOSAVE' quirk (for this driver).
Also, avoid overwriting the residual count if a SENSE was appended to
the current transaction.
