slightly, but autoinitialize mode is impossible to use reliably, since it
means that if disc interrupts are blocked for long enough (or sec_copyout
is too slow), the uPD71071 can run off the end of a block before the
base registers have been updated and end up processing the same block
twice. With this change, the SEC in my A540 seems finally to be solid.
line is not printed at all. This is specified in P1003.1-2004
(SUSv3), and is useful.
* Customised headers may contain embedded space, commas and equals
signs. To specify multiple customised headers, use multiple -o or -O
options. This is specified (for "-o", not for "-O") in P1003.1-2004
(SUSv3), and is useful.
* When a column is given a null (blank) customised header, it keeps its
default minimum width. This is specified in P1003.1-2004 (SUSv3), and
seems harmless.
* Fix a bug that made it impossible to print the same keyword multiple
times, with different customised headers each time. (Previously, the
last customised header was used for all instances of the keyword.)
* Make the behaviour of "-O" more useful. The first -O option adds
the default keywords only if there have not yet been any formatting
options, and multiple -O options now insert their keywords in adjacent
positions. Now {ps -j -O %cpu} is like {ps -j} with one extra column;
Previously, it would have had all the columns implied by "-j", plus
all the default columns, plus the extra column specified by "-O".
* Convert from home-grown linked lists to SIMPLEQ lists.

recent bugs introduced with the usage of kauth(9) in MD/device code.
While here, change the sanity checks to KASSERT(), because they're really
bugs we should fix if triggered.
DBAU1550. This is parameterized somewhat as machdep pluggable code, so
different boards can supply different implementations.
At the moment, the DBAU1550 is the only Au1550 board I know of with SPI
connected devices.
I have not enabled I2C on the DBAU1550, as we do not have drivers for either
of the I2C connected devices (a different temperature/voltage sensor and
a serial eeprom.)
The main changes needed are:
1) pass address and IRQ information from aubus (auspi uses interrupts)
2) all Au1550 PSC protocols have the same status and register bits
for enable, so clean that up (clock registers could be different)
3) improve timeout logic on enable (a fixed delay isn't good enough)
4) make aupsc_print return QUIET, as it is annoying to see messages
for unconfigured protocols. This whole mechanism should be re-
engineered, to either use indirect configuration or provide more
detailed board-driven configuration. A comment to that effect is
placed in the source.
This is shown to work on DBAU1550.
a sample driver for the TI TMP121 temperature sensor. This has been
moderately tested on Au1550, and it is not enabled in sys/conf (yet). So
the change is harmless at worst, and useful at best.
Alchemy Au1550 bus driver forthcoming, along with a driver for SPI flash
devices, such as found on the Meraki Mini
This development was partially funded by the Champaign-Urbana Community
Wireless Network Project.
Note that there are some MD-specific SPI drivers that could probably be
made MI under this new framework.
