- Define various new AFMT_*. These are not returned as supported
formats by SNDCTL_DSP_GETFMTS, because it would be very silly to
have Vorbis in the kernel.
- Implement PLAYTGT and RECSRC. For each NetBSD audio device
we only return one playback and recording source, "primary".
- Return preferred channel configuration in capabilities.
Either DSP_CH_STEREO, DSP_CH_MONO, or DSP_CH_MULTI
depending on the current hardware format.
- SNDCTL_DSP_HALT_* simply flushes the audio device.
on arm64eb resuming vi(1) would often crash. in makech(), the 'csp'
variable is either set to current window data, or a local stack
variable's address '&blank'. the window data has many lines of info
stored, and 'csp++' is used per line here. unfortunately, a case
existed where 'csp++' operated on csp initialised from '&blank' which
eventually crashes when, on my display with 160 columns and 'csp + 155'
exceeds the mapped stack and crashes.
match the '!_cursesi_screen->curwin' conditional that initialises csp,
and avoid csp++ here. assert() that csp != &blank in both places that
modify csp.
thanks to jdc@ and mlelstv@.
XXX: possibly also should avoid the putch() here as well.
Darwin in libc compilation
We build the regex code in tools without nls. We don't include any nls headers
for that, but on Darwin wint_t gets defined, so we end up with a compilation
error. The cleaner fix would have been to always use regex_foo_t types, but
the minimal fix is to only do this for the tools build, using cpp.
memset() and emitting calls to memset() where it seems code that looks
like what memset() does, which ends up recursing and blowing the stack.
this makes mips userland with GCC 10 work.
signals. This introduces a new kernel and userland NVMM version indicating
this support.
Patch by Kamil Rytarowski <kamil@netbsd.org> and committed on his request.
This is the missing libnvmm part I forgot to include in the origional commit.
Before it was based on the heuristic that we were not supplied an
attempted_completion_function, which worked well because programs
that supplied that function were not shells and did not want/understand
shell quoting. Recently though Piotr Stefaniak wanted to enhance command
completion for the Bourne Shell and this could benefit quoting the returned
command. This function adds an extra flags argument that controls that quoting.
some drivers (not hdaudio(4), but uaudio(4), eap(4), sb(4), various other
old cards) will return error if a AUDIO_MIXER_VALUE is requested and the
number of channels is not specified as input. this is not documented as
well as it should be, unfortunately.
