| 09-Apr-2012 |
plunky | branches: 1.25.14; 1.25.16; Tidy up a little, the way that midi attachment code works
- change midi_attach() to omit the 'parent' arg (there are only two callers of this and it is not used)
- change midisyn_attach() to midisyn_init(), so not needing a midi_softc, and fix the midi_pcppi driver to set hw_if and hw_hdl directly in its midi_softc before calling midi_attach()
- add a device_t to opl_softc structure, change opl drivers to store the device 'self' in opl_softc and fix opl_attach() to use this opl_softc->dev field directly rather than a field in an otherwise unused midi_softc
- remove unnecessary midi_softc from opl and cms drivers (child device provides that)

mrg | branches: 1.24.2; begin to document the per-midi call backs and locking.
XXX: lots more to do.

1.23 |
| 23-Nov-2011 |
jmcneill | Merge jmcneill-audiomp3 branch, which is derived from ad-audiomp2. From the original ad-audiomp branch notes:
Add MP locking to the audio drivers.
Making the audio drivers MP safe is necessary before efforts can be made to make the VM system MP safe.
The are two locks per device instance, an ISR lock and a character device lock. The ISR lock replaces calls to splaudio()/splx(), and will be held across calls to device methods which were called at splaudio() before (e.g. trigger_output). The character device lock is held across calls to nearly all of the methods, excluding some only used for initialization, e.g. get_locks.
Welcome to 5.99.57.

bouyer | Update thorpej_scsipi to -current as of a month ago A i386 GENERIC kernel compiles without the siop, ahc and bha drivers (will be updated later). i386 IDE/ATAPI and ncr work, as well as sparc/esp_sbus. alpha should work as well (untested yet). siop, ahc and bha will be updated once I've updated the branch to current -current, as well as machine-dependant code.

darrenr | Apply the aborted ktrace-lwp changes to a specific branch. This is just for others to review, I'm concerned that patch fuziness may have resulted in some errant code being generated but I'll look at that later by comparing the diff from the base to the branch with the file I attempt to apply to it. This will, at the very least, put the changes in a better context for others to review them and attempt to tinker with removing passing of 'struct lwp' through the kernel.

1.17.14.13 |
| 31-May-2006 |
chap | Allow getinfo (and therefore midiplay -l) to reveal something useful for umidi devices.
Annotate devices that lack output interrupts in the dmesg with (cpu- intensive output) so users can easily tell which ones to prefer for bulk output.
|
1.17.14.12 |
| 30-May-2006 |
chap | A flag is added to the midi_hw_if_ext struct for the hardware to specify that it would like compression of data to be transmitted. It will still receive a message at a time, with the status and channel passed as arguments, but the message buffer will omit the status byte when possible. umidi now uses this flag when talking to Midiman devices, which do not do their own compression, so as to make best use of the MIDI 1.0 bandwidth on the far side.
|
1.17.14.11 |
| 26-May-2006 |
chap | Guard against having to invent /another/ interface-extension hack at some future time....
|
1.17.14.10 |
| 20-May-2006 |
chap | Now for Phase Two. The patched files have been rolled forward again, with a naive mechanical resolution of conflicts. Now to compare the diffs and make sure the resolutions made sense. Sleep first.
|
1.17.14.9 |
| 20-May-2006 |
chap | Learned of two ugly corners in MIDI protocol that made the state machine overly pedantic. Both have to do with the End SysEx byte, 0xf7. First, it is allowed not only at the end of a SysEx message, but anywhere else any status byte can appear (and in that case has no meaning). Second, it is not even required at the end of a SysEx message - any subsequent status byte implicitly ends the SysEx, and this is not considered an error.
I don't like these provisions because they make it even harder to detect errors in a corrupted MIDI stream, but as MIDI gets sent increasingly over error-correcting transports I suppose that is less of a concern. In any case, though midi(4) will accept data (input from device or data from write(2)) with stray or dropped End SysEx bytes, it will always ensure that output to the device, and data for read(2), has End SysEx only and always at the ends of SysEx messages.
|
1.17.14.8 |
| 20-May-2006 |
chap | Spotted a bug in a buffer condition. Never saw any symptom, but it's a bug nonetheless.
|
1.17.14.7 |
| 20-May-2006 |
chap | The two choices CN_SEQ_GLOBAL and CN_SEQ_PER_EP cannot cover all devices, some are wired arbitrarily oddly and need a CN_FIXED quirk to specify the cable number mappings explicitly. But then as a result of those mappings, the automatically bound mididevice unit numbers might not match the order of the device's physical jacks or blinkenlights, so an MD_FIXED quirk is needed to specify that order as well. It turns out the cn_base field added earlier was neither necessary (at the time) nor sufficient (to handle CN_FIXED), so it's gone now.
Q: How do you tell when you've got the cable number associations wrong on a Midisport 2x4? A: Everything works right except data-rate throttling - you'll be able to send data to certain ports at rates far in excess of the MIDI data rate (and lose most of it). If you never transmit that fast, you'll never notice.
So testing for a sane data transfer rate (use dd to blast a stream of MIDI data at the rmidi device, it'll report the rate on completion) is probably a wise testing step when adding support for a new umidi device.
|
1.17.14.6 |
| 20-May-2006 |
chap | Patch to account explicitly for the prior inconsistency in the treatment of cable numbers. Also contains a (functionally insignificant) change to the declaration of endpoint buffers introduced in kern/32441, which will be useful in a forthcoming patch. This patch should be fuzz-free on 2.0 source after the 32441 and 32442 patches.
|
1.17.14.5 |
| 20-May-2006 |
chap | Active Sense now handled for receive as well as for transmit. Following the spec, if no Active Sense is seen on receive, no special behavior applies, but if an Active Sense is seen then any absence of received data exceeding 300ms thereafter will be signalled as a read EOF on the rmidi device. Receipt of any further data will clear the EOF condition, and operation resumes as if no Active Sense has been seen.
Also moved some selnotify's out of locks so they don't deadlock against the corresponding kevent filters.
This concludes this round of midi hacking (except for possibly improving the safety of how pending callouts and interrupts are canceled on device detach. Other fixes/enhancements to the midi subsystems will get their own patches.
|
1.17.14.4 |
| 20-May-2006 |
chap | The FST now handles the equivalence between NoteOn (velocity 0) and a NoteOff with velocity 64, both for canonicalizing (always produce NoteOff) and compressing (produce whichever allows a current running status to be exploited). The code from sequencer that attempted to model this behavior and running status has been superseded and removed. Also removed the EBADF checks I added to sequencer earlier, as they're handled in a layer above.
|
1.17.14.3 |
| 20-May-2006 |
chap | umidi now uses hw_if_ext and no longer has its own approximate midi state machine. This patch is relative to umidi.c and umidivar.h already patched by midiman.pat (kern/32441).
|
1.17.14.2 |
| 20-May-2006 |
chap | Added hw_if_ext for hw drivers that want their messages intact rather than byte by byte. Works with midisyn - must still integrate and test with umidi.
|
1.17.14.1 |
| 20-May-2006 |
chap | Now for Phase One. The patches to be applied in sequence were created and tested against 2.0 sources. To begin, let CVS roll the affected files back to that historic state. The reverse operation will be used (and will involve some manual merging) after the patches have been applied. Naturally, intermediate stages on this branch will not be directly compilable (unless merged into a 2.0 checkout).

CID/1261465: Dereference after NULL check. CID/1261467: Unreachable code actually fix one of the previous: don't test for NULL after deref.
