skrll@ reports that with this patch he can record and playback audio.
Suprisingly the bug was actually with playback and not with capture.
When not capturing or playing audio we write to or read from "empty
buffers", the problem was that playback and capture were using the same
buffer and the playback code managed to pick up a bit of data that was
written from the capture code.
since bootst was written. Grab 3MB of the kernel image from tape
in hackprom_diskrd() instead of 2MB.
Bump bootst version on account of the above fix.
While here, use -Os instead of -O2 to compile mvme68k stand code.
than 32k.
A bootconf file is normally only a few hundred bytes long. If it is
much bigger than expected, we can't load it into an 8086 real mode
segment anyway.
Much more to the point, in the pxeboot case, someone may have
configured their dhcpd to return the filename for the kernel, not
realizing that the filename is now for boot.cfg which didn't used to
be the case. If we try to load the kernel here, thinking it is
boot.cfg by accident, the boot loader will die ignominiously and
without much of an error message, so we don't want to do that.
This needs to be pulled up to 5.0 if 5.0 has all this machinery
-- I'm not sure whether it does.
Make copyin(9) and copyout(9) work with 64KB or larger data blocks.
Fixes broken pipe(2) problem mentioned in PR port-vax/41139. Ok'ed by ragge@.
Should be pulled up to netbsd-5.
<sys/device.h> now requires <sys/mutex.h> for struct device_lock, and
<machine/mutex.h> requires <machine/intr.h> for ipl_cookie_t, so
including <sys/device.h> from <machine/intr.h> causes recursive dependency.
elansc_attach().
Let us detach gpio0 at elansc0.
Let us re-attach pci0 at elansc0.
Reduce code duplication between elansc_rescan() and elansc_attach():
call _rescan() from _attach() to attach elanpex0, elanpar0, gpio0, and
pci0.

Do not compile in the local variable "mba" in mainbus_rescan unless
NPNPBIOS > 0 || NACPI > 0 || NIPMI > 0 || NMCA > 0. This fixes the
build on systems such as Soekris where none of those options apply.
Extract code from mainbus_attach() to create a rescan hook,
mainbus_rescan(). Call mainbus_rescan(, "acpibus"/"ipmibus"/..., ) from
mainbus_attach() in the precise places where we used to attach acpi0,
ipmi0, pnpbios0, and mca0. This allows, for example, ipmi0 to detach
and re-attach:
# drvctl -d ipmi0
ipmi0: detached
# drvctl -r -a ipmibus mainbus0
ipmi0 at mainbus0
#
Future work will let us detach & re-attach CPUs and the ISA/PCI/EISA
buses at mainbus0.
than one active reference to a file descriptor. It should dislodge threads
sleeping while holding a reference to the descriptor. Implemented only for
sockets but should be extended to pipes, fifos, etc.
Fixes the case of a multithreaded process doing something like the
following, which would have hung until the process got a signal.
thr0 accept(fd, ...)
thr1 close(fd)
