2012-09-11ALSA: hda - Avoid BDL position workaround when no_period_wakeup is setTakashi Iwai1-5/+7
Originally the bogus period at BDL head was introduced as a workaround for the mismatching position update at the period boundary, typically seen on dmix. However, for applications like PulseAudio that don't require period wake ups, this workaround is just superfluous. Thus better to disable it when no_period_wakeup is given in hw_params.

2012-09-11ALSA: hda_intel: add position_fix quirk for Asus K53ECatalin Iacob1-0/+1
Commit c20c5a841cbe47f5b7812b57bd25397497e5fbc0 changed some chipsets to default to POS_FIX_COMBO so they now use POS_FIX_LPIB instead of POS_FIX_POSBUF. Since then I've been getting artifacts on playback, including repeated sounds on my Asus laptop. My hardware is Cougar Point which the commit log of c20c5a841cbe47f5b7812b57bd25397497e5fbc0 mentions as tested so POS_FIX_COMBO probably works in general but apparently it doesn't on Asus K53E therefore the need for the quirk.

2012-09-11ALSA: compress_core: fix open flags test in snd_compr_open()Dan Carpenter1-5/+3
O_RDONLY is zero so the original test (f->f_flags & O_RDONLY) is always false and it will never do compress capture. The test for O_WRONLY is also slightly off. The original test would consider "->flags = (O_WRONLY | O_RDWR)" as write only instead of rejecting it as invalid. I've also removed the pr_err() because that could flood dmesg.

2012-09-10ALSA: hda - Fix Oops at codec reset/reconfigTakashi Iwai1-1/+1
snd_hda_codec_reset() calls restore_pincfgs() where the codec is powered up again, which eventually tries to resume and initialize via the callbacks of the codec. However, it's the place just after codec free callback, thus no codec callbacks should be called after that. On a codec like CS4206, it results in Oops due to the access in init callback. This patch fixes the issue by clearing the codec callbacks properly after freeing codec.

2012-09-07ALSA: hda - Remove ignore_misc_bitDavid Henningsson3-8/+2
The purpose of this flag is unclear. If the problem is that some machines have broken misc/NO_PRESENCE bits, they should be fixed by pin fixups. In addition, this causes jack detection functionality to be flawed on the M31EI, where there are two jacks without jack detection (which is properly marked as NO_PRESENCE), but due to ignore_misc_bit, these jacks are instead being reported as being present but always unplugged.

2012-09-06ALSA: hda - Move non-PCM check to per_pin in patch_hdmi.cTakashi Iwai1-21/+25
Recently the check for non-PCM stream state was added to the generic HDMI driver code. But this check should be done rather to each pin instead of each converter. Otherwise when a different converter is assigned at the next open, the audio infoframe can be inconsistent with the setup using the previous converter. For fixing this issue, this patch moves the state of the current non-PCM status from per_cvt to per_pin. (In addition an unused argument cvt_nid is stripped from hdmi_setup_channel_mapping()) Signed-off-by: Takashi Iwai <tiwai@suse.de>
2012-09-06ALSA: usb-audio: Fix bogus error messages for delay accountingTakashi Iwai1-0/+6
The recent fix for the missing fine delayed time adjustment gives strange error messages at each start of the playback stream, such as delay: estimated 0, actual 352 delay: estimated 353, actual 705 These come from the sanity check in retire_playback_urb(). Before the stream is activated via start_endpoints(), a few silent packets have been already sent. And at this point the delay account is still in the state as if the new packets are just queued, so the driver gets confused and spews the bogus error messages. For fixing the issue, we just need to check whether the received packet is valid, whether it's zero sized or not.

2012-09-04ALSA: snd-usb: Add quirks for Playback Designs devicesDaniel Mack5-0/+49
Playback Designs' USB devices have some hardware limitations on their USB interface. In particular: - They need a 20ms delay after each class compliant request as the hardware ACKs the USB packets before the device is actually ready for the next command. Sending data immediately will result in buffer overflows in the hardware. - The devices send bogus feedback data at the start of each stream which confuse the feedback format auto-detection. This patch introduces a new quirks hook that is called after each control packet and which adds a delay for all devices that match Playback Designs' USB VID for now. In addition, it adds a counter to snd_usb_endpoint to drop received packets on the floor. Another new quirks function that is called once an endpoint is started initializes that counter for these devices on their sync endpoint.

2012-08-31ALSA: snd-usb: fix calls to next_packet_sizeDaniel Mack3-13/+8
In order to support devices with implicit feedback streaming models, packet sizes are now stored with each individual urb, and the PCM handling code which fills the buffers purely relies on the size fields now. However, calling snd_usb_audio_next_packet_size() for all possible packets in an URB at once, prior to letting the PCM code do its job does in fact not lead to the same behaviour than what the old code did: The PCM code will break its loop once a period boundary is reached, consequently using up less packets that it really could. As snd_usb_audio_next_packet_size() implements a feedback mechanism to the endpoints phase accumulator, the number of calls to that function matters, and when called too often, the data rate runs out of bounds. Fix this by making the next_packet function public, and call it from the PCM code as before if the packet data sizes are not defined.

When a codec provides its own set_power_state op, the D3-clock-stop isn't checked correctly. And the recent changes for repeating the state-setting operation isn't applied to such a codec, too. This patch fixes these issues by moving the call of codec's own op to the place where the generic power-set operation is done, and move the power-state synchronization code out of snd_hda_set_power_state_to_all() so that it can be called always at the end of power-up/down sequence, and updates the D3 clock-stop flag properly.

For fixing the unbalance, and cleaning up the code mess, this patch changes the following: - change pm_notify callback to take the explicit power on/off state, - check of D3 stop-clock and keep_link_on flags is moved to the caller side, - call pm_notify callback in snd_hda_codec_new() and snd_hda_codec_free() so that the refcounts are proprely updated.

Commit e9ba389c5 ("ALSA: usb-audio: Fix scheduling-while-atomic bug in PCM capture stream") fixed a scheduling-while-atomic bug that happened when snd_usb_endpoint_start was called from the trigger callback, which is an atmic context. However, the patch breaks the idea of the endpoints reference counting, which is the reason why the driver has been refactored lately.

2012-08-28ALSA: emu8000: fix emu8000 DRAM sized 512 KiB too smallDavid Flater1-3/+12
v2: Fixed result still wrong in the case of 512 KiB DRAM. Oops. Applicable to 3.5.3 mainline. In emu8000.c, size_dram determines the amount of memory on the sound card by doing write/readback tests starting at 512 KiB and incrementing by 512 KiB. On success, detected_size is updated to the successful address and testing continues. On failure, the loop is immediately exited. The resulting detected_size is 512 KiB too small except in two special cases: 1. If there is no memory, the initial 0 value of detected_size is used, which is correct. 2. If the address space wraps around, detected_size is updated before the bailout, so the result is correct. The patch corrects all cases and was tested with an AWE64 Gold. Before: EMU8000 [0x620]: 3584 Kb on-board memory detected asfxload 4GMGSMT.SF2 (4174814 B) fails. After: EMU8000 [0x620]: 4096 Kb on-board memory detected asfxload 4GMGSMT.SF2 succeeds. I do not have a card with 512 KiB to test with, but by forcibly enabling the added conditional I verified on the AWE64 Gold that it detects 512 KiB (successfully reading from the first memory location) and does not hang the card.

2012-08-23ALSA: hda - add runtime PM supportMengdong Lin3-20/+87
Runtime PM can bring more power saving: - When the controller is suspended, its parent device will also have a chance to suspend. - PCI subsystem can choose the lowest power state the controller can signal wake up from. This state can be D3cold on platforms with ACPI PM support. And runtime PM can provide a gerneral sysfs interface for a system policy manager. Runtime PM support is based on current HDA power saving implementation. The user can enable runtime PM on platfroms that provide acceptable latency on transition from D3 to D0. Details: - When both power saving and runtime PM are enabled: -- If a codec supports 'stop-clock' in D3, it will request suspending the controller after it enters D3 and request resuming the controller before back to D0. Thus the controller will be suspended only when all codecs are suspended and support stop-clock in D3. -- User IO operations and HW wakeup signal can resume the controller back to D0. - If runtime PM is disabled, power saving just works as before. - If power saving is disabled, the controller won't be suspended because the power usage counter can never be 0. More about 'stop-clock' feature: If a codec can support targeted pass-through operations in D3 state when there is no BCLK present on the link, it will set CLKSTOP flag in the supported power states and report PS-ClkStopOk when entering D3 state.

2012-08-21ALSA: introduce snd-cmi8328: C-Media CMI8328 driverOndrej Zary3-0/+496
Introduce snd-cmi8328 driver for C-Media CMI8328-based sound cards, such as AudioExcel AV500. It supports PCM playback and capture (full-duplex) through wss_lib, gameport, OPL3 and MPU401. The AV500 card has onboard Dream wavetable synth connected to the MPU401 port and Aux 1 input internally which works too. The CDROM interface is not supported (as the drivers for these CDROMs were removed from the kernel some time ago). A separate driver is needed because CMI8328 is completely different chip to CMI8329/CMI8330. It's configured by magic registers (there's no PnP). Sound is provided by a real WSS codec (CS4231A) and the SB part is just a SB Pro emulation (for DOS games, useless for Linux). When SB is enabled, the CMI8328 chip disables access to the WSS codec, emulates SoundBlaster on one side and outputs sound data to the codec - so SB and WSS can't work together with this card. The WSS codec can do full duplex by itself so there's no need for crazy things like snd-cmi8330 does (combining SB and WSS parts into one driver).
