augustss 48bae9ee88 Add MIDI support. The MIDI devices can be accessed as ``raw'' through 
the /dev/rmidiN devices, or with a sequencer interface via /dev/music.
So far the only supported MIDI device is the MPU401 port on SoundBlaster
(and only on SB on isapnp, since we do not have locators with multiple
values yet).

thorpej 37b70b3064 Change the "aresid" argument of vn_rdwr() from an int * to a size_t *, 
to match the new uio_resid type.

thorpej 33f066d24c Implement the shrinking and no-change bits of the Linux mremap(2) system 
call, provided by Urban Boquist <boquist@cs.chalmers.se> in PR #5693.

Add a comment about how one might implement the growing bit of mremap(2).

mycroft 26c238db7d Linux's getsid(2) does in fact return a pid, not a pointer. 1998-02-20 18:09:04 +00:00
kleink 96f0dccbdd * Use sys___posix_{chown,fchown}() instead of sys_{chown,fchown}(). 
* Change reference from sys_posix_rename() to sys___posix_rename().
 1998-02-14 21:57:02 +00:00
thorpej 821a4fec46 Add a comment clearly describing that Linux's getsid(2) differs from 
the XPG4.2 definition in that it returns the kernel virtual address
of the session structure, rather than the process group ID of the
session leader.

fvdl af221f1c41 msync -> __msync13 1997-10-21 00:57:38 +00:00
thorpej 14cd99880c Fix the shared library versioning snafu caused by the recent changes 
to the stat(2) family and msync(2).  This uses a primitive function
versioning scheme.

This reverts the libc shared library major version from 13 to 12, and
adds a few new interfaces to bring us to libc version 12.20.

From Frank van der Linden <fvdl@NetBSD.ORG>.

mycroft 523d84775a Emulate mremap(2) by returning ENOMEM for now. This should be sufficient for 
realloc(3) and other uses.  From Matthias Scheler in PR 3920.

fvdl d6e5e295fa Signal error when getting a 64 bit offset cookie that can't be stored 
in 32 bits. Provide an error message to the user, and return EINVAL.
Also, pay attention to the EOF flag from VOP_READDIR. Correct a
misspell in a panic message.

kleink c80051ee4e Add missing preparation of F_GETLK parameters in linux_sys_fcntl(); fixes PR 
port-i386/4083 from Matthias Scheler <tron@lyssa.owl.de>, but vastly cleaned
up as previously suggested by myself.

bouyer 1cd83a5971 Fix "missing entries" bug when reading large directories: When reading a 
directory and running out of space in the dest buffer, off should point to the
current entry (which was not saved) and not to the next.
I discovered this bug using linux and SunOS emulation over NFS, but seems to
affect other emulations as well.

augustss 9745684ebe Changes to the sudio system: 
- It is now possible to handle devices that want "looping" DMA,
    e.g. the SoundBlaster correctly.  The WSS and SB drivers use this.
    To do this several new methods were introduced in audio_hw_if.
  - Different silence handling (forced by previous change).
  - The audio driver can now be mmap()-ed, but due to problems in
    the VM system only for writing for now.
  - The OSS (Linux) audio emulation takes advantage of some of the
    new features.
 1997-07-27 01:16:32 +00:00
kleink 96588fead9 Use sys_posix_rename() instead of sys_rename() as it's the behaviour of the 
native implementation.

OSS (aka VoxWare) audio emulation.
* Use the OSS audio emulation for Linux and FreeBSD.
* Add mixer emulation to the OSS emulator.

cgd 9c3e274c7b adapt ELF-using compat code to use new ELF definitions/code. At this point,

christos 4d9a6e0930 - Pass the Elf32_Ehdr in the linux probe function, and use it! 
Since linux binaries are (mostly) always compiled with gcc, look for
the gcc signature in the .comment section header: "\0 GCC: (GNU) ".
I've changed the probe order in kern/exec_elf.c to probe for linux ELF
binaries first and fall back to SVR4 binaries. This makes statically
linked binaries work for both linux and svr4. Note that gcc-compiled
svr4 binaries, still contain the operating system signature first and
then the GCC signature, so there is no conflict. Yes this is a hack.
