Raw Normal View History

Linux-2.6.12-rc2 Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

[ALSA] prevent oops & dead keyboard on usb unplugging while the device is being used USB generic driver,USB USX2Y Without this patch, some usb kobjects, which are parents to the usx2y's kobjects can be freed before the usx2y's. This led to an oops in get_kobj_path_length() and a dead keyboard, when the usx2y's kobjects were freed. The patch ensures the correct sequence. Tested ok on kernel 2.6.12-rc2.

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.

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
Version 0.8.2:
Avoid any possible racing while in prepare callback.
2004-09-30 Karsten Wiese
Version 0.8.0:
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:
Runs with 2.6.1 kernel.
2003-12-30 Karsten Wiese
Version 0.4.1:
Fix 24Bit 4Channel capturing for the us428.
2003-11-27 Karsten Wiese, Martin Langer
Version 0.4:
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.
2003-08-22 Karsten Wiese
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.

IRQ: Maintain regs pointer globally rather than passing to IRQ handlers Maintain a per-CPU global "struct pt_regs *" variable which can be used instead of passing regs around manually through all ~1800 interrupt handlers in the Linux kernel. The regs pointer is used in few places, but it potentially costs both stack space and code to pass it around. On the FRV arch, removing the regs parameter from all the genirq function results in a 20% speed up of the IRQ exit path (ie: from leaving timer_interrupt() to leaving do_IRQ()). Where appropriate, an arch may override the generic storage facility and do something different with the variable. On FRV, for instance, the address is maintained in GR28 at all times inside the kernel as part of general exception handling. Having looked over the code, it appears that the parameter may be handed down through up to twenty or so layers of functions. Consider a USB character device attached to a USB hub, attached to a USB controller that posts its interrupts through a cascaded auxiliary interrupt controller. A character device driver may want to pass regs to the sysrq handler through the input layer which adds another few layers of parameter passing. I've build this code with allyesconfig for x86_64 and i386. I've runtested the main part of the code on FRV and i386, though I can't test most of the drivers. I've also done partial conversion for powerpc and MIPS - these at least compile with minimal configurations. This will affect all archs. Mostly the changes should be relatively easy. Take do_IRQ(), store the regs pointer at the beginning, saving the old one: struct pt_regs *old_regs = set_irq_regs(regs); And put the old one back at the end: set_irq_regs(old_regs); Don't pass regs through to generic_handle_irq() or __do_IRQ(). In timer_interrupt(), this sort of change will be necessary: - update_process_times(user_mode(regs)); - profile_tick(CPU_PROFILING, regs); + update_process_times(user_mode(get_irq_regs())); + profile_tick(CPU_PROFILING); I'd like to move update_process_times()'s use of get_irq_regs() into itself, except that i386, alone of the archs, uses something other than user_mode(). Some notes on the interrupt handling in the drivers: (*) input_dev() is now gone entirely. The regs pointer is no longer stored in the input_dev struct. (*) finish_unlinks() in drivers/usb/host/ohci-q.c needs checking. It does something different depending on whether it's been supplied with a regs pointer or not. (*) Various IRQ handler function pointers have been moved to type irq_handler_t.
