Here is a list of HP300 specific kernel compilation options and what they
mean:
HP320
Support for HP320 machines: 16MHz 68020, HP MMU, 16MHz 68881 and VAC.
Compiles in support for a VAC, HP MMU, and the 98620A 16-bit DMA
channel.
HP350
Support for HP350 machines: 25MHz 68020, HP MMU, 20MHz 68881 and VAC.
Compiles in support for a VAC and the HP MMU. Differs from HP320 in
that it has no support for 16-bit DMA controller.
HP330
Support for HP330 (and 318, 319) machines: 16MHz 68020, 68851 PMMU
and 16MHz 68881. Compiles in support for PMMU.
HP340
Support for HP340 machines: 25MHz 68030+MMU and 25MHz 68882. Compiles
in support for PMMU and 68030. Differs from HP330 in support for
68030 on-chip data cache.
HP345
HP360
HP370
HP375
HP400
Support for HP345, 360, 370, 375 and 400 machines: 33 (or 50) MHz
68030+MMU and 33 (or 50) MHz 68882. Compiles in support for PMMU,
68030 and off-chip physically addressed cache. Differs from 340
in only one place, in dealing with flushing the external cache.
HP380
HP385
HP425
HP433
Support for HP380, 385, 425 and 433 machines: 25 (or 33) MHz 68040
with MMU/FPU. Compiles in support for 68040.
USELEDS
Twinkle the HP4xx front panel (or HP3xx internal) LEDs in the HP
designated way. Somewhat frivolous, but the heartbeat LED is
useful to see if your machine is alive.
DEBUG
Compiles in a variety of consistency checks and debug printfs
throughout the hp300 MD code and device drivers.
COMPAT_HPUX
Enables HP-UX binary compatibility mode. Allows a variety of
"recent" HP-UX m68k binaries to be run unchanged. Due to the
evolutionary and "as-needed" nature of this code, "recent" is
anywhere from release 6.2 to 8.0 of HP-UX. It will run 8.0
shared-library binaries (assuming all the necessary shared-libraries
are installed in the filesystem).
DCMSTATS
Compile in code to collect a variety of transmit/receive statistics
for the 98642 4-port MUX.
WAITHIST
Compile in code to collect statistics about the distribution of
wait-times for various busy waits in the SCSI host-adaptor driver.
