2005-06-22[ALSA] Remove redundant NULL checks before kfreeJesper Juhl
Timer Midlevel,ALSA sequencer,ALSA<-OSS sequencer,Digigram VX core I2C tea6330t,GUS Library,VIA82xx driver,VIA82xx-modem driver CA0106 driver,CS46xx driver,EMU10K1/EMU10K2 driver,YMFPCI driver Digigram VX Pocket driver,Common EMU synth,USB generic driver,USB USX2Y Checking a pointer for NULL before calling kfree() on it is redundant, kfree() deals with NULL pointers just fine. This patch removes such checks from sound/ This patch also makes another, but closely related, change. It avoids casting pointers about to be kfree()'ed.

2005-05-29[ALSA] usb-audio - fix synchronization packet interval with Audigy 2 NXClemens Ladisch
USB generic driver When a device does not provide the bRefresh field in its audio endpoint descriptors, use the bInterval field instead. Furthermore, increase the number of sync URBs for better queueing. Signed-off-by: Clemens Ladisch <clemens@ladisch.de>
2005-05-29[ALSA] usb-audio - avoid unnecessary double bufferingClemens Ladisch
USB generic driver When a USB packet boundary falls exactly on a buffer boundary, hwptr remains at the end of the buffer which causes an overflow in the next iteration and triggers double buffering although the next packet would actually be contiguous. This patch ensures that hwptr is always smaller than buffer_size. Signed-off-by: Clemens Ladisch <clemens@ladisch.de>
2005-05-29[ALSA] usb-audio - sanity-check sync feedback frequency valuesClemens Ladisch
USB generic driver Check that the synchronization feedback frequency values returned by the device are more or less near the nominal frequency. Signed-off-by: Clemens Ladisch <clemens@ladisch.de>
2005-05-29[ALSA] usb-audio - bind to control interface instead of usb_deviceClemens Ladisch
USB generic driver Bind the device files to the (first) audio control interface instead of the entire USB device. Signed-off-by: Clemens Ladisch <clemens@ladisch.de>
2005-05-29[ALSA] usb-audio - enable high speed (not) on Audigy 2 NXClemens Ladisch
USB generic driver The SB Audigy 2 NX needs a special boot-up command before it works in high speed mode. However, we don't actually enable it yet because high speed synchronization doesn't seem to work with this device. Signed-off-by: Clemens Ladisch <clemens@ladisch.de>
2005-05-29[ALSA] usb-audio - set sample rate attribute on Audigy 2 NX endpointsClemens Ladisch
USB generic driver The SB Audigy 2 NX does not advertise the sample rate attribute in its endpoint descriptors although it supports it. Signed-off-by: Clemens Ladisch <clemens@ladisch.de>
2005-05-29[ALSA] usb-audio - use only one packet in synchronization feedback URBsClemens Ladisch
USB generic driver Do not use more than one packet in synchronization feedback URBs because it would be pointless to send or receive more than one value at the same time. Signed-off-by: Clemens Ladisch <clemens@ladisch.de>
2005-05-29[ALSA] usb-audio - use proper interval between synchronization packetsClemens Ladisch
USB generic driver Add sanity checks when reading the bRefresh value, and actually use it for the synchronization packets instead of polling at 1000 Hz. Signed-off-by: Clemens Ladisch <clemens@ladisch.de>
2005-05-29[ALSA] usb-audio - cache vendor/product IDsClemens Ladisch
USB generic driver Cache the decoded values of idVendor/idProduct to get rid of most of those ugly le16_to_cpu() calls. Signed-off-by: Clemens Ladisch <clemens@ladisch.de>
2005-05-29[ALSA] usb-audio - move mixer data into separate structClemens Ladisch
USB generic driver Move all data related to audio control interfaces into a separate struct local to usbmixer.c. Signed-off-by: Clemens Ladisch <clemens@ladisch.de>
2005-05-29[ALSA] usb-audio - restrict Audigy 2 NX frequencies to 48/96 kHzClemens Ladisch
USB generic driver On the SB Audigy 2 NX, frequency feedback doesn't quite work when playing at 44.1 kHz, so temporarily disable this frequency. Signed-off-by: Clemens Ladisch <clemens@ladisch.de>
2005-05-29[ALSA] usb-audio - remove superfluous parameterClemens Ladisch
USB generic driver,USB USX2Y This patch removes the superfluous driver parameter from the disconnect functions. Signed-off-by: Clemens Ladisch <clemens@ladisch.de>
2005-05-29[ALSA] usb-audio - show exact synchronous frequency in proc fileClemens Ladisch
USB generic driver In the streamX proc file, show the exact number of samples per USB frame as 16.16 hexadecimal floating point value. Signed-off-by: Clemens Ladisch <clemens@ladisch.de>
2005-05-29[ALSA] prevent oops & dead keyboard on usb unplugging while the device is ↵Karsten Wiese
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.

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!
