isaki | Merge isaki-audio2 branch, the overhaul of audio subsystem.
- Interrupt-oriented system rather than thread-oriented.
- Improve stability, quality and performance.
- Split playback and record cleanly. Improve halfduplex support.
- Many bugs are fixed including deadlocks, resource leaks, abuses, etc.
- Simplify audio filter mechanism. The encoding/channels/frequency
conversions are completely handled in the upper layer. So the hard-
ware driver only converts its hardware encoding (if necessary).
- audio_hw_if changes:
- Obsoletes query_encoding and add query_format instead.
- Obsoletes set_params and add set_format instead.
- Remove drain, setfd, mappage.
- The call sequences are changed.
- ioctl AUDIO_GETFD/SETFD, AUDIO_GETCHAN/SETCHAN are obsoleted.
- ioctl AUDIO_{QUERY,GET,SET}FORMAT are introduced.
- cleanup config attributes: au*conv and mulaw.
- All hardware drivers should follow it (I've done as much as possible).
Some file paths are changed:
- dev/audio.c -> dev/audio/audio.c (rewritten)
- dev/audiovar.h -> dev/audio/audiovar.h
- dev/audio_dai.h -> dev/audio/audio_dai.h
- dev/audio_if.h -> dev/audio/audio_if.h
- dev/audiobell.c -> dev/audio/audiobell.c
- dev/audiobellvar.h -> dev/audio/audiobellvar.h
- dev/mulaw.[ch] -> dev/audio/mulaw.[ch] + dev/audio/alaw.c

reinoud | branches: 1.66.2;
Add headers for support functions for kgdb
|
| 1.65 |
| 04-Jun-2018 |
reinoud | branches: 1.65.2;
Enhance the NetBSD/usermode thunk interface
|
| 1.64 |
| 01-Jun-2018 |
reinoud | Pretend we already included the <types.h>
|
| 1.63 |
| 18-May-2018 |
reinoud | Include OUR types.h and not the machine's. A small step to allow for
crosscompilation.
|
| 1.62 |
| 06-Feb-2015 |
prlw1 | branches: 1.62.16;
Take procfs_machdep.c rev 1.4 one step further and adjust signature of
thunk_getcpuinfo().
|
| 1.61 |
| 03-Mar-2012 |
reinoud | branches: 1.61.2; 1.61.16;
Implement signal forwarding to userland for usermode kernels. Especially
SIGFPE is important since the urkel shouldn't stop when a userland program
devides by zero!
|
| 1.60 |
| 21-Jan-2012 |
reinoud | branches: 1.60.2;
Add the complement to sigemptyset(), sigfillset()!
|
| 1.59 |
| 11-Jan-2012 |
reinoud | Add thunk_close()
|
| 1.58 |
| 10-Jan-2012 |
reinoud | Add thunk_madvise() for memory access hints to the host kernel.
|
| 1.57 |
| 06-Jan-2012 |
jmcneill | support disk images >= 2GB
|
| 1.56 |
| 05-Jan-2012 |
jmcneill | Get rid of MAP_NOSYSCALLS usage; now this relies on a separate kmod that
you can get here: http://www.netbsd.org/~jmcneill/syscallemu.tar
|
| 1.55 |
| 03-Jan-2012 |
reinoud | Rename the debug printf's to use a thunk_ prefix to avoid confusion.
|
| 1.54 |
| 31-Dec-2011 |
christos | Adjust prototypes.
|
| 1.53 |
| 30-Dec-2011 |
jmcneill | report rfb pointer events
|
| 1.52 |
| 30-Dec-2011 |
jmcneill | add a barrier before copyrows(), and add an RRE based fillrect functino,
use it for eraserows and erasecols
|
| 1.51 |
| 30-Dec-2011 |
jmcneill | support wskbd bell
|
| 1.50 |
| 30-Dec-2011 |
reinoud | Use the encoding values of the VNC spec and add a copyrect (not used yet)
|
| 1.49 |
| 30-Dec-2011 |
reinoud | Add RFB type flag to indicate what kind of request is waiting
|
| 1.48 |
| 30-Dec-2011 |
jmcneill | optimize rfb updates by allowing queueing of multiple update messages,
dropping duplicates, and transmitting them in batches
|
| 1.47 |
| 29-Dec-2011 |
jmcneill | Replace the SDL based genfb driver with a wsdisplay and wskbd driver that
implements the VNC (RFB) protocol.
To enable the VNC server, add 'vnc=640x480,5900' to the kernel command line
(where 640x480 is the desired fb resolution and 5900 is the TCP port).
Screenshot of it here: http://www.netbsd.org/~jmcneill/usermode.tiff
|
| 1.46 |
| 26-Dec-2011 |
jmcneill | add vaudio(4) audio device driver
|
| 1.45 |
| 26-Dec-2011 |
jmcneill | first cut at networking support for usermode, doesn't fully work yet but
enough to get an address with dhcp and answer arps
|
| 1.44 |
| 20-Dec-2011 |
jmcneill | on second thought, set machine and machine_arch both from the host and
override module_machine
|
| 1.43 |
| 20-Dec-2011 |
jmcneill | set machine_arch to that of the host
|
| 1.42 |
| 20-Dec-2011 |
reinoud | Use to the MAP_NOSYSCALLS argument to mmap() to allow for NetBSD/usermode to
execute bog-standard native programs.
|
| 1.41 |
| 15-Dec-2011 |
jmcneill | Improve usermode timecounter. It's unreasonable to assume that we'll get
100 "SIGALRM" per second with an ITIMER_REAL at 100Hz on a HZ=100 host as
the timer may expire before a pending signal has been delivered.
Instead of setitimer, use timer_create + timer_settime and from our
intr handler use timer_getoverrun to determine how many ticks we have
missed.
|
| 1.40 |
| 15-Dec-2011 |
jmcneill | implement /proc/cpuinfo
|
| 1.39 |
| 15-Dec-2011 |

|
| 1.37 |
| 12-Dec-2011 |
jmcneill | make sure to set O_ASYNC on stdin to enable ttycons "interrupts"
|
| 1.36 |
| 11-Dec-2011 |
jmcneill | add thunk_pollchar
|
| 1.35 |
| 27-Nov-2011 |

Add thunk_sigprocmask()
|
| 1.34 |
| 15-Sep-2011 |
reinoud | branches: 1.34.2;
Implement a dprintf_debug() analog to aprint_debug() but printing it to stderr
using vdprintf() to bypass the kernel buffer. It is currently printing only on
the -x boot flag but might get a more specific one since its quite verbose!
|
| 1.33 |
| 14-Sep-2011 |
reinoud | Provide thunk fuction to return the host machine's VM_MIN_ADDRESS
|
| 1.32 |
| 09-Sep-2011 |

reinoud | -thunk_makecontext_trapframe2go(ucontext_t *ucp, void *func, void *trapframe)
+thunk_makecontext_1(ucontext_t *ucp, void *func, void *arg)
|
| 1.25 |
| 03-Sep-2011 |
jmcneill | Let NetBSD/usermode build & link on a Linux host:
- Need to add options CPU_HOST=i386 or CPU_HOST=amd64 for membar & atomic_ops
- Don't use MAP_* and PROT_* with thunk API since the kernel and host
might not be the same; add THUNK_MAP_* and THUNK_PROT_* and translate them
- Add thunk_posix_memalign
- allocate mem_uvm with thunk_posix_memalign instead of thunk_malloc
- Fix thunk_mmap callers to always pass either THUNK_MAP_PRIVATE or
THUNK_MAP_SHARED
- mkstemp on Linux requires exactly 6 "X" characters at the end of the
template string, so add an X
|
| 1.24 |
| 03-Sep-2011 |
jmcneill | Get this compiling (but not quite linking yet) on Linux
|
| 1.23 |
| 02-Sep-2011 |

|
| 1.22 |
| 02-Sep-2011 |

|
| 1.20 |
| 28-Aug-2011 |
jmcneill | add thunk_tcgetattr and thunk_tcsetattr
|
| 1.19 |
| 28-Aug-2011 |
reinoud | Add thunk_makecontext_trapframe2go()
|
| 1.18 |
| 27-Aug-2011 |
reinoud | Add a thunk_atexit() so ucontext() ends can be dealt with as they should
|
| 1.17 |
| 25-Aug-2011 |
jmcneill | - build thunk code with warnings
- add option SDL which pulls in thunk_sdl code and links the kernel to libSDL
- add an experimental framebuffer driver based on thunk_sdl, enable with:
options SDL
genfb* at mainbus?
wsdisplay* at genfb?
options WS_KERNEL_FG=WSCOL_GREEN

| 1.16 |
| 24-Aug-2011 |
reinoud | Implement thunk_malloc() and think_free()
|
| 1.15 |
| 23-Aug-2011 |
jmcneill | add a wrapper for signal(3)
|
| 1.14 |
| 23-Aug-2011 |
jmcneill | struct stat also has time_t in it, so we can't use that in the thunk api either
|
| 1.13 |
| 23-Aug-2011 |
jmcneill | more time_t fixes
|
| 1.12 |
| 23-Aug-2011 |
jmcneill | unlink pmap backing file immediately after opening it, so we don't leave
a bunch of 128MB turds sitting around in /tmp
|
| 1.11 |
| 23-Aug-2011 |
jmcneill | more host vs. userkernel time_t fixes
|
| 1.10 |
| 23-Aug-2011 |
jmcneill | host and userkernel timespec might differ in size (because of time_t) so
instead of thunk_clock_getres() filling in a timespec, use instead
thunk_clock_getres_monotonic() that returns the resolution as a long
|
| 1.9 |
| 22-Aug-2011 |
reinoud | Add thunk_munmap() to NetBSD/usermode's thunk
|
| 1.8 |

jmcneill | add a simple disk driver, pass the path to the disk image on the kernel command line:
soundwave$ ./netbsd /tmp/test.fs
NetBSD/usermode startup
[...]
ld0 at mainbus0: /tmp/test.fs (33554432)
ld0: 32768 KB, 8322 cyl, 64 head, 63 sec, 1 bytes/sect x 33554432 sectors
boot device: ld0
root on ld0a dumps on ld0b
|
| 1.2 |
| 12-Aug-2011 |
jmcneill | implement reboot using execv
|
| 1.1 |
| 12-Aug-2011 |
jmcneill | Clean up extern mess by adding an API for kernel components to call libc
functions. thunk.c is built with special cflags that makes it compile
against standard system headers instead of kernel ones.
