2008-01-08Revert "hda_intel suspend latency: shorten codec read"Linus Torvalds
This reverts commit 57a04513cb35086d54bcb2cb92e6627fc8fa0fae. Harald Dunkel reports that it broke sound for him: "Alsa stopped working for me. I still can access /dev/dsp, change the volume and so on, but the speakers are quiet." Reverting it fixed things for him.

2008-01-06hda_intel suspend latency: shorten codec readIngo Molnar
not sleeping for every codec read/write but doing a short udelay and a conditional reschedule has cut suspend+resume latency by about 1 second on my T60. The patch also fixes the unexpected codec-connection errors that happen more often in the new power-save mode: http://lkml.org/lkml/2007/11/8/255 http://bugzilla.kernel.org/show_bug.cgi?id=9332 Signed-off-by: Ingo Molnar <mingo@elte.hu> Acked-by: Takashi Iwai <tiwai@suse.de> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>

2007-10-16[ALSA] alsa-kernel: schedule_timeout() fixesRene Herman
Fix schedule_timeout() use in alsa-kernel. Mostly just schedule_timeout(1) --> schedule_timeout_uninterruptible(1) The wavefront_synth one fixes the surrounding loop as well. In ymfpci_main, delete a superfluous set_current_state() and in soc/soc-dapm.c replace an _interruptible with _uninterruptible in some debug code; it's not waiting for signals.

2007-10-16[ALSA] hda-intel - Fix resume logic, when dynamic power managment is onMaxim Levitsky
Comment in hda_intel.c states that 'the explicit resume is needed only when POWER_SAVE isn't set', but this is not true. There is no code that will automaticly power up the codec on resume, but only code that powers it up when user accesses it. So if user leaves a sound playing, codec will not be powered To fix that I check if there are any codecs that should be powered codec->power_count, and if so I power them up together with main controller.

2007-10-16[ALSA] hda-intel - Add POWER_SAVE optionTakashi Iwai
Added CONFIG_SND_HDA_POWER_SAVE kconfig. It's an experimental option to achieve an aggressive power-saving. With this option, the driver will turn on/off the power of each codec and controller chip dynamically on demand. The patch introduces a new module option 'power_save'. It specifies the second of time-out for automatic power-down. As default, it's 10 seconds. Setting 0 means to suppress the power-saving feature. The codec may have analog-input loopbacks, which are usually represented by mixer elements such as 'Mic Playback Switch' or 'CD Playback Switch'. When these are on, we cannot turn off the mixer and the codec chip has to be kept on. For bookkeeping these states, a new codec-callback is introduced. For the bus-controller side, a new callback pm_notify is introduced, which can be used to turn on/off the contoller appropriately. Note that this power-saving might cause slight click-noise at power-on/off. Also, it might take some time to wake up the codec, and might even drop some tones at the very beginning. This seems to be the side-effect of turning off the controller chip. This turn-off of the controller can be disabled by undefining HDA_POWER_SAVE_RESET_CONTOLLER in hda_intel.c.

2007-05-11[ALSA] hda-intel - Fix detection of audio codec on Toshiba A100Takashi Iwai
Some boards have the audio codec on slot #3 while the modem codec on slot #0. The driver should continue to probe the slots when no audio codec is found.

2007-05-11[ALSA] hda-intel - Probe additional slots only if necessaryTakashi Iwai
Probing the codec slots on ATI controller causes problems on some devices like Acer laptops. On these devices, reading from codec slot 3 results in the communication failure with the codec chip. Meanwhile, some laptops (e.g. Gateway) have the codec connection only on slot 3, and probing this slot is mandatory for them. The patch improves the probing robustness. The additional slots are now checked only when no codecs are found in the primary three slots. Signed-off-by: Takashi Iwai <tiwai@suse.de> Signed-off-by: Jaroslav Kysela <perex@suse.cz>

2007-03-14[ALSA] hda-intel - Fix codec probe with ATI contorllersTakashi Iwai
ATI controllers may have up to 4 codecs while ICH up to 3. Thus the earlier fix to change AZX_MAX_CODECS to 3 cause a regression on some devices that have the audio codec at bit#3. Now max codecs is defined according to the driver type, either 3 or 4. Currently 4 is set only to ATI chips. Other might need the same change, too.

2006-10-05IRQ: Maintain regs pointer globally rather than passing to IRQ handlersDavid Howells
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.
