percpu.h is included by sched.h and module.h and thus ends up being included when building most .c files. percpu.h includes slab.h which in turn includes gfp.h making everything defined by the two files universally available and complicating inclusion dependencies. percpu.h -> slab.h dependency is about to be removed. Prepare for this change by updating users of gfp and slab facilities include those headers directly instead of assuming availability. As this conversion needs to touch large number of source files, the following script is used as the basis of conversion. http://userweb.kernel.org/~tj/misc/slabh-sweep.py The script does the followings. * Scan files for gfp and slab usages and update includes such that only the necessary includes are there. ie. if only gfp is used, gfp.h, if slab is used, slab.h. * When the script inserts a new include, it looks at the include blocks and try to put the new include such that its order conforms to its surrounding. It's put in the include block which contains core kernel includes, in the same order that the rest are ordered - alphabetical, Christmas tree, rev-Xmas-tree or at the end if there doesn't seem to be any matching order. * If the script can't find a place to put a new include (mostly because the file doesn't have fitting include block), it prints out an error message indicating which .h file needs to be added to the file. The conversion was done in the following steps. 1. The initial automatic conversion of all .c files updated slightly over 4000 files, deleting around 700 includes and adding ~480 gfp.h and ~3000 slab.h inclusions. The script emitted errors for ~400 files. 2. Each error was manually checked. Some didn't need the inclusion, some needed manual addition while adding it to implementation .h or embedding .c file was more appropriate for others. This step added inclusions to around 150 files. 3. The script was run again and the output was compared to the edits from #2 to make sure no file was left behind. 4. Several build tests were done and a couple of problems were fixed. e.g. lib/decompress_*.c used malloc/free() wrappers around slab APIs requiring slab.h to be added manually. 5. The script was run on all .h files but without automatically editing them as sprinkling gfp.h and slab.h inclusions around .h files could easily lead to inclusion dependency hell. Most gfp.h inclusion directives were ignored as stuff from gfp.h was usually wildly available and often used in preprocessor macros. Each slab.h inclusion directive was examined and added manually as necessary. 6. percpu.h was updated not to include slab.h. 7. Build test were done on the following configurations and failures were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my distributed build env didn't work with gcov compiles) and a few more options had to be turned off depending on archs to make things build (like ipr on powerpc/64 which failed due to missing writeq). * x86 and x86_64 UP and SMP allmodconfig and a custom test config. * powerpc and powerpc64 SMP allmodconfig * sparc and sparc64 SMP allmodconfig * ia64 SMP allmodconfig * s390 SMP allmodconfig * alpha SMP allmodconfig * um on x86_64 SMP allmodconfig 8. percpu.h modifications were reverted so that it could be applied as a separate patch and serve as bisection point. Given the fact that I had only a couple of failures from tests on step 6, I'm fairly confident about the coverage of this conversion patch. If there is a breakage, it's likely to be something in one of the arch headers which should be easily discoverable easily on most builds of the specific arch.

Version 0.8.7.2:
|
|
Call snd_card_free() instead of snd_card_free_in_thread() to prevent oops with dead keyboard symptom.
|
|
Tested ok with kernel 2.6.12-rc2.
|
|
|
|
2004-12-14 Karsten Wiese
|
|
Version 0.8.7.1:
|
|
snd_pcm_open for rawusb pcm-devices now returns -EBUSY if called without rawusb's hwdep device being open.
|
|
|
|
2004-12-02 Karsten Wiese
|
|
Version 0.8.7:
|
|
Use macro usb_maxpacket() for portability.
|
|
|
|
2004-10-26 Karsten Wiese
|
|
Version 0.8.6:
|
|
wake_up() process waiting in usX2Y_urbs_start() on error.
|
|
|
|
2004-10-21 Karsten Wiese
|
|
Version 0.8.5:
|
|
nrpacks is runtime or compiletime configurable now with tested values from 1 to 4.
|
|
|
|
2004-10-03 Karsten Wiese
|

|
Simplified things and made ohci work again.
|
|
|
|
2004-09-20 Karsten Wiese
|
|
Version 0.7.3:
|
|
Use usb_kill_urb() instead of deprecated (kernel 2.6.9) usb_unlink_urb().
|
|
|
|
2004-07-13 Karsten Wiese
|
|
Version 0.7.1:
|
|
Don't sleep in START/STOP callbacks anymore.
|
|
us428 channels C/D not handled just for this version, sorry.
|
|
|
|
2004-06-21 Karsten Wiese
|
|
Version 0.6.4:
|
|
Temporarely suspend midi input
|
|
to sanely call usb_set_interface() when setting format.
|
|
|
|
2004-06-12 Karsten Wiese
|
|
Version 0.6.3:
|
|
Made it thus the following rule is enforced:
|
|
"All pcm substreams of one usX2Y have to operate at the same rate & format."
|
|
|
|
2004-04-06 Karsten Wiese
|
|
Version 0.6.0:
|
|
Runs on 2.6.5 kernel without any "--with-debug=" things.
|
|
us224 reported running.
|
|
|
|
2004-01-14 Karsten Wiese
|
|
Version 0.5.1:

|
|
|
|
2003-11-27 Karsten Wiese, Martin Langer
|
|

|
|
us122 support.
|
|
us224 could be tested by uncommenting the sections containing USB_ID_US224
|
|
|
|
2003-11-03 Karsten Wiese
|
|
Version 0.3:
|
|
24Bit support.
|
|
"arecord -D hw:1 -c 2 -r 48000 -M -f S24_3LE|aplay -D hw:1 -c 2 -r 48000 -M -f S24_3LE" works.
|
|

|
Version 0.0.8:
|
|
Removed EZUSB Firmware. First Stage Firmwaredownload is now done by tascam-firmware downloader.
|
|
See:
|
|
http://usb-midi-fw.sourceforge.net/tascam-firmware.tar.gz
|
|
|
|
2003-06-18 Karsten Wiese
|
|
Version 0.0.5:
|
|
changed to compile with kernel 2.4.21 and alsa 0.9.4
|
|
|
|
2002-10-16 Karsten Wiese
|
|
Version 0.0.4:
|
|
compiles again with alsa-current.
|
|
USB_ISO_ASAP not used anymore (most of the time), instead
|
|
urb->start_frame is calculated here now, some calls inside usb-driver don't need to happen anymore.
|
|
|
|
To get the best out of this:
|
|
Disable APM-support in the kernel as APM-BIOS calls (once each second) hard disable interrupt for many precious milliseconds.
|
|
This helped me much on my slowish PII 400 & PIII 500.
|
|
ACPI yet untested but might cause the same bad behaviour.
|
|
Use a kernel with lowlatency and preemptiv patches applied.
|
|
To autoload snd-usb-midi append a line
|
|
post-install snd-usb-us428 modprobe snd-usb-midi
|
|
to /etc/modules.conf.
|
|
|
|
known problems:
|
|
sliders, knobs, lights not yet handled except MASTER Volume slider.
|
|
"pcm -c 2" doesn't work. "pcm -c 2 -m direct_interleaved" does.
|
|
KDE3: "Enable full duplex operation" deadlocks.
|
|
|
|
|
|
2002-08-31 Karsten Wiese
|
|
Version 0.0.3: audio also simplex;
|
|
simplifying: iso urbs only 1 packet, melted structs.
|
|
ASYNC_UNLINK not used anymore: no more crashes so far.....
|
|
for alsa 0.9 rc3.
|
|
|
|
2002-08-09 Karsten Wiese
|
|
Version 0.0.2: midi works with snd-usb-midi, audio (only fullduplex now) with i.e. bristol.
|
|
The firmware has been sniffed from win2k us-428 driver 3.09.
