- 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.
a bug in the adoption of the MBR handling code and fix the original
conversion bug instead:
- run fdisk to install the MBR bootcode on the raw disk partition
- run installboot against the NetBSD root partition (not the raw partition).
Instead of using negative flags to turn on positive flags, set -DRPC
in the makefile. Corrects a problem where the SunRPC code in parse.c
was accidentally left disabled.
This is a prime example of why we don't like negative flags...
Installboot can install U-Boot boot blocks directly into a system
image. Normally, the U-Boot files are searched for in
/usr/pkg/share/u-boot, under the expectation that most people will
build them with pkgsrc. However, it is also possible to set an
environment variable (INSTALLBOOT_UBOOT_PATHS) to a colon-separated
search path to accommodate other situations. This commit adds a
command line option (-u) to set the search path; if present, it
overrides the environment and default.
a totaly different part of the disk. Fix size handling for freshly
added partitions (which would previously use random stack data due to
bogus error checking).
which have not (yet) been touched (-xD needs *serious* improvements).
While this still has no run-time configurability, it is now easy to
adjust the column widths in the source and recompile. Dynamic (auto)
column width sizing is probably out of the question (requires predicting
the future) but options to allow the widths to be set isn't out of the
question.
The columns are now (mostly) considerably wider than they were before,
hence wider windows are needed to view the same info. In an 80
column window the default display (with tty & cpu included) displays
just 2 drives. 160 columns will fit 7 (but with -I, just 4).
One new option added (-z) suppresses output which is true 0 (but still
prints 0 for values rounded down to 0) for everything except tty stats.
For drive output, the drive must have done nothing during the interval
to get its output data blanked.
Also options -H h -W w to set the output size (page height & width), the
former used to decide when to print headers, and the latter to calculate
the number of drives to print when no drive names were given. Env vars
LINES and COLUMNS are used if the options are not given, with fallback
to the terminal size (if output is to a terminal, and its sizes are
known), and if all else fails, 20 lines, 80 columns. Specifying 0
means unlimited (infinite). So "iostat -W 0" will show all of the
drives, across one (often very) long line. Wedges count as drives.
When drives are specified, the output will now appear in the order they were
given on the command line, rather than the order the system discovered them
during auto-configuration. If specified as an fnmatch(3) pattern, drives that
match will appear in auto-conf order, but that's generally what is wanted.
When none are specified, you still get the first N (however many fits based
upon the options selected) in auto-conf order (usually useless, more so now
given that less will fit).
Lastly, for those who looked at the patch I sent to current-users@
and were horrified at how kludgey it was, rest assured, that was just
a quick hack to demonstrate what the output format changes would look
like. This version (I hope) is not nearly so disgusting.
doesn't repeat the processing every iteration. Repeatedly seeing the wait
interval does no harm, but setting the iteration count (reps) over and
over again rather defeats its purpose.
the /s modifier to the ddb trace command (trace/s, bt/s).
The default is trace with framepointer (same as before).
This allows backtracing even on kernels compiled with -fomit-frame-pointer.
allow conditionally disabling the building of certain user space
programs in the 'base' set.
There is not enough consensus that this is the right way and a few
people had strong objections, see source-changes-d@.
suggested fixes from Tom Lane. I played it safe and went with (my
variation of) the minimal fix.
port-hppa/56118: sporadic app crashes in HPPA -current
Patch from RVP on NetBSD-Users, with an additional comment tweak by me.
Summary from RVP:
1. Ignore SIGPIPE so that we're not killed in the middle of some
DB operation by a botched $PAGER:
$ env PAGER=/non-existent apropos -p ...
2. Return proper exit status in case of write errors:
$ apropos ... >/dev/full || echo fail
