- Mention that the 'fmt' argument to these functions holds
a printf(3)-like format specification.
- Clarify that the err()/warn()/errc()/warnc() family of functions
will append an additional error message to the output.
- Add whitespace to separate paragraphs describing distinct
concepts.
- Move the sentence mentioning the final output newline to
a less ambiguous location within the text.
- Add a cross-reference to printf(3).
The debug output contained too many newlines.
The buffer functions were built into lint2 even though they weren't
used.
Enable the query for invisible characters in string literals, to make
sure that a newline in a string literal does not trigger that query.
In the examples using hex escape sequences, there must be a delimiter
between the escape sequence and the following description if the
description starts with [A-Fa-f], as hex escape sequences are not
limited in length.
Distinguish between a 'directive' (bit + length + description) and a
'description' (only the text).
The fmt parameter is not a string, as strings only reach to the first
'\0' byte, but the new-style format may include additional '\0' as bit
numbers.
- use bus_space_*_stream() for all register accesses in order to avoid
byte order conversion on PCI devices
- when switching to framebuffer mode, request as many text planes as STI allows
- request access to both text and non-text planes in fb mode
With this and the bus_space commit a few days ago I have usable X on my C360
and a PCI Visualize EG.
This needs testing on quite literally everything else.
For jobs -p for a non-job-control job, avoid just printing 0 (as
there is no process group pid) and instead output what we used to,
the pid of one of the processes in the job (usually the right one!)
XXX pullup -10 (9 and earlier not affected).
The plain char literals are needed for checking printf/scanf format
strings; lint has no similar check for wide strings. These format
strings are checked by modern compilers, making this check less
relevant.
The fix for PR kern/57890 in hdafg.c 1.29 included more conditionals
than needed, covering cases that can't happen: if allocm returns
null, audio(4) does not call freem; and if hdafg_allocm returns
nonnull, then what audio(4) passes to hdafg_freem had better be
either the playback or the capture buffer address.
file flags, only system ones. Restrict those to the superuser. Before
the behavior was controlled by EXT2FS_SYSTEM_FLAGS. Make that behavior the
default.
Drop frames if the RX descriptor ring has no room. This is enabled only on
multiqueue system to avoid bad influence to other queues. The drop count
can be seen by the RQDPC counter (wmN rxqXXdrop evcnt).
The iqdrops counter should include not only MPC(Missed Packet Count)
but also RQDPC(Receive Queue Drop Packet Count). Same as ixgbe(4) and igc(4).
Note that the RQDPC is not currently counted because SRRCTL_DROP_EN
is not set.
i915 now calls into this with a spin lock held, so we have to use
ipi(9), which spin-waits for the other CPUs to complete, rather than
xcall(9), which may sleep-wait.
Fortunately, this is just to execute WBINVD on x86 (and if this code
ever runs on other architectures, which it probably doesn't, it'll be
a similar barrier instruction), so spinning to wait for that on all
CPUs isn't too costly.
