* [ALSA] usbaudio - Revert the minimal period size fix patchTakashi Iwai2007-05-111-3/+4
| | | | | | | | | | The last patch didn't really work (false report). Although the hardware supports 125us minimum period, the current usb-audio driver code assumes the 1ms period in many places. Rollback the change. Signed-off-by: Takashi Iwai <tiwai@suse.de> Signed-off-by: Jaroslav Kysela <perex@suse.cz>

* [ALSA] usbaudio - Add support for Edirol UA-101Bjoern Fay2007-02-091-0/+53
| | | | | | | | | | | | | | | | Added support for the Edirol UA-101 (only in high-speed mode) by taking the quirks for the UA-1000 and change them accordingly. Changes were made in 'usbaudio.c', 'usbaudio.h', and 'usbquirks.h' MIDI and recording seem to work perfectly (with JACK), but playback gives some few glitches. I think that's the mentioned synchronizing-problem in the UA-1000 quirk ('FIXME: playback must be synchronized to capture'), so I didn't change that.

* IRQ: Maintain regs pointer globally rather than passing to IRQ handlersDavid Howells2006-10-051-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* [ALSA] Support for non-standard rates in USB audio driverLuke Ross2006-09-231-0/+46
| | | | | | | | | | | | | There's at least one USB audio chipset out there which supports only one non-standard rate (ID 0e6a:0310 supports 46875Hz). There's a few other patches for this card which are unsatisfactory because they attempt to map this rate to 44.1k leading to sound distortion.

* [ALSA] usb-audio support for Turtle Beach RoadieSam Revitch2006-06-281-0/+32
| | | | | | | | | | | | | | | | | From: Sam Revitch <sam.revitch@gmail.com>Recently a Turtle Beach Audio Advantage Roadie device ended up in my possession. It seems to work with the snd-usb-audio driver, but only using the headphone jack in 2-channel mode. The device has a DIN connector carrying six more channels that are otherwise silent. C-Media has freely available documentation for the CM106 chip around which this device is based, and enabling 8-channel output, or 6-channel output with the headphone jack following the front pair is a matter of setting one of its registers. Attached is a patch to try to enable 5.1 output mode at probe time. It seems to work correctly with my device. There is quite list of other configurables for this device that might deserve controls.

* [PATCH] USB: URB_ASYNC_UNLINK flag removed from the kernelAlan Stern2005-09-091-6/+4Star
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 29 July 2005, Cambridge, MA: This afternoon Alan Stern submitted a patch to remove the URB_ASYNC_UNLINK flag from the Linux kernel. Mr. Stern explained, "This flag is a relic from an earlier, less-well-designed system. For over a year it hasn't been used for anything other than printing warning messages." An anonymous spokesman for the Linux kernel development community commented, "This is exactly the sort of thing we see happening all the time. As the kernel evolves, support for old techniques and old code can be jettisoned and replaced by newer, better approaches. Proprietary operating systems do not have the freedom or flexibility to change so quickly." Mr. Stern, a staff member at Harvard University's Rowland Institute who works on Linux only as a hobby, noted that the patch (labelled as548) did not update two files, keyspan.c and option.c, in the USB drivers' "serial" subdirectory. "Those files need more extensive changes," he remarked. "They examine the status field of several URBs at times when they're not supposed to. That will need to be fixed before the URB_ASYNC_UNLINK flag is removed." Greg Kroah-Hartman, the kernel maintainer responsible for overseeing all of Linux's USB drivers, did not respond to our inquiries or return our calls. His only comment was "Applied, thanks."
