the disklabel name "4.2BSD" could show up initially but we could never
go back to it via the menu used to change the file system type.
This was confusing.
- Added "tprof count" subcommand to perform counts only.
- Event options (u,k) are now optional. The default value is both userland and kernel. (:uk)
- Event counters can be displayed with SIGINFO during `tprof monitor' or `tprof count'.
- Multiple events can now be handled simultaneously.
- Counters should be configured with TPROF_IOC_CONFIGURE_EVENT in advance,
instead of being configured at TPROF_IOC_START.
- The configured counters can be started and stopped repeatedly by
PROF_IOC_START/TPROF_IOC_STOP.
- The value of the performance counter can be obtained at any timing as a 64bit
value with TPROF_IOC_GETCOUNTS.
- Backend common parts are handled in tprof.c as much as possible, and functions
on the tprof_backend side have been reimplemented to be more primitive.
- The reset value of counter overflows for profiling can now be adjusted.
It is calculated by default from the CPU clock (speed of cycle counter) and
TPROF_HZ, but for some events the value may be too large to be sufficient for
profiling. The event counter can be specified as a ratio to the default or as
an absolute value when configuring the event counter.
- Due to overall changes, API and ABI have been changed. TPROF_VERSION and
TPROF_BACKEND_VERSION were updated.
attribute support to be exercised and tested.
If you want to share a new installed disk with older NetBSD
installations or (read only) with other OSes you need to explicitly set
the FS type to FFSv2 now.
atmospheric pressure sensor. This is an inexpensive to moderately
expensive chip available from a large number of places. The driver
supports all aspects of the two chips, except for the repeating read
mode which would allow for sub-second queries, such as fall detection
or perhaps even as an altimeter. This driver also only supports the
I2C interface and not the SPI interface.
The BME280, the one with humidity, is not fully tested at this point,
awaiting upon a breakout board and may not show proper humidity.
disabling support in UFS2 for extended attributes (including ACLs).
Add a new variant of UFS2 called "UFS2ea" that does support extended attributes.
Add new fsck_ffs operations "-c ea" and "-c no-ea" to convert file systems
from UFS2 to UFS2ea and vice-versa (both of which delete all existing extended
attributes in the process).
Make it possible to specify the debug message categories with an
optional numeric argument. You'll have to read the fine source to
find out what they are. The number can be specified as the usual
decimal, hex (0x), or octal (0) literal with an optional ~negation.
Since syslogd uses getopt(3), not getopt_long(3), do a bit of
gymnastics so that both -d42 and -d 42 are accepted (I'm not inventing
long names for all the existing options just to support an optional
argument to -d).
-d without an argument still uses the old D_DEFAULT selection just in
case someone really relies on that. You can disable all debug
messages with -d0 but still get syslogd not daemonized.
