In clause 6.3 of IEC 61883-6:2000, there's an explanation about processing of presentation timestamp. In the clause, we can see "If a function block receives a CIP, processes it and subsequently re-transmits it, then the SYT of the outgoing CIP shall be the sum of the incoming SYT and the processing delay." ALSA firewire stack has an implementation to partly satisfy this specification. Developers assumed the stack to perform as an Audio function block[1]. Following to the assumption, current implementation of ALSA firewire stack use one software interrupt context to handle both of in/out packets. In most case, this is processed in 1394 OHCI IR context independently of the opposite context. Thus, this implementation uses longer CPU time in the software interrupt context. This is not better for whole system. Against the assumption, I confirmed that each ASIC for IEC 61883-1/6 doesn't necessarily expect it to the stack. Thus, current implementation of ALSA firewire stack includes over-engineering. This commit purges the implementation. As a result, packets of one direction are handled in one software interrupt context and spends minimum CPU time.

In packet streaming protocol applied to TASCAM FireWire series, the value of SYT field in CIP header is always zero, therefore it has no meaning. There's no need to synchronize packets in both direction for the series. In current implementation of ALSA firewire stack, driver for the series uses incoming packet parameter for outgoing packet parameter to calculate the number of data blocks. This can be simplified because the task of corresponding driver is to transfer data blocks enough to sampling transfer frequency. This commit purges support of full duplex synchronization to prevent over-engineering implementation. Signed-off-by:

On Fireworks board module of Echo Audio, TSB43Cx43A (IceLynx Micro, iCEM) is used to process payload of isochronous packets. There's an public document of this chip[1]. This document is for firmware programmers to transfer/receive AMDTP with IEC60958 data format, however in clause 2.5, 2.6 and 2.7, we can see system design to utilize the sequence of value in SYT field of CIP header. In clause 2.3, we can see the specification of Audio Master Clock (MCLK) from iCEM. Well, this clock is actually not used for sampling clock. This can be confirmed when corresponding driver transfer random value as the sequence of SYT field. Even if in this case, the unit generates proper sound. Additionally, in unique command set for this board module, the format of CIP is changed; for IEC 61883-6 mode which we use, and for Windows Operating System. In the latter mode, the whole 32 bit field in second CIP header from Windows driver is used to represent counter of packets (NO-DATA code is still used for packets without data blocks). If the master clock was physically used by DSP on the board module, the Windows driver must have transferred correct sequence of SYT field. Furthermore, as long as seeing capacities of AudioFire2, AudioFire4, AudioFire8, AudioFirePre8 and AudioFire12, these models don't support SYT-Match clock source. Summary, we have no need to relate incoming/outgoing packets. This commit drops reusing SYT sequence of incoming packets for outgoing packets.

Windows driver for BeBoB-based models mostly wait for transmitted packets, then transfer packets to the models. This looks for the relationship between incoming packets and outgoing packets to synchronize the sequence of presentation timestamp. However, the sequence between packets of both direction has no relationship. Even if receiving NO-DATA packets, the drivers transfer packets with meaningful value in SYT field. Additionally, the order of starting packets is always the same, independently of the source of clock. The corresponding driver is expected as a generator of presentation timestamp and these models can select it as a source of sampling clock. This commit drops reusing SYT sequence from ALSA bebob driver. The driver always transfer packets with presentation timestamp generated by ALSA firewire stack, without re-using the sequence of value in SYT field in incoming packets to outgoing packets.

The HD-audio reconfig function got broken in the recent kernels, typically resulting in a failure like: snd_hda_intel 0000:00:1b.0: control 3:0:0:Playback Channel Map:0 is already present This is because of the code restructuring to move the PCM and control instantiation into the codec drive probe, by the commit [bcd96557: ALSA: hda - Build PCMs and controls at codec driver probe]. Although the commit above removed the calls of snd_hda_codec_build_pcms() and *_build_controls() at the controller driver probe, the similar calls in the reconfig were still left forgotten. This caused the conflicting and duplicated PCMs and controls. The fix is trivial: just remove these superfluous calls from reconfig_codec(). Fixes: bcd96557 ('ALSA: hda - Build PCMs and controls at codec driver probe') Reported-by:

Since the recent rewrite of HD-audio infrastructure, CONFIG_SND_HDA_RECONFIG has a slightly different meaning. In the earlier versions, it implicitly assumed only the usage via hwdep sysfs entries. Meanwhile, in the recent version, this option is meant to enable the reconfig code in HD-audio driver, which may be used by the patch loader without hwdep interface. This patch tries to clarify the usage pattern a bit better, hopefully avoid the further confusion. Reported-by:

When audio and music units have some quirks in their sequence of packet, it's really hard for non-owners to identify the quirks. Although developers need dumps for sequence of packets, it's difficult for users who have no knowledges and no equipments for this purpose. This commit adds tracepoints for this situation. When users encounter the issue, they can dump a part of packet data via Linux tracing framework as long as using drivers in ALSA firewire stack. Additionally, tracepoints for outgoing packets will be our help to check and debug packet processing of ALSA firewire stack. This commit newly adds 'snd_firewire_lib' subsystem with 'in_packet' and 'out_packet' events. In the events, some attributes of packets and the index of packet managed by this module are recorded per packet. This is an usage: $ trace-cmd record -e snd_firewire_lib:out_packet \ -e snd_firewire_lib:in_packet /sys/kernel/tracing/events/snd_firewire_lib/out_packet/filter /sys/kernel/tracing/events/snd_firewire_lib/in_packet/filter Hit Ctrl^C to stop recording ^C $ trace-cmd report trace.dat ... 23647.033934: in_packet: 01 4073 ffc0 ffc1 00 000f0040 9001b2d1 122 44 23647.033936: in_packet: 01 4074 ffc0 ffc1 00 000f0048 9001c83b 122 45 23647.033937: in_packet: 01 4075 ffc0 ffc1 00 000f0050 9001ffff 002 46 23647.033938: in_packet: 01 4076 ffc0 ffc1 00 000f0050 9001e1a6 122 47 23647.035426: out_packet: 01 4123 ffc1 ffc0 01 010f00d0 9001fb40 122 17 23647.035428: out_packet: 01 4124 ffc1 ffc0 01 010f00d8 9001ffff 002 18 23647.035429: out_packet: 01 4125 ffc1 ffc0 01 010f00d8 900114aa 122 19 23647.035430: out_packet: 01 4126 ffc1 ffc0 01 010f00e0 90012a15 122 20 (Here, some common fields are omitted so that a line to be within 80 characters.) ...

In callback function of isochronous context, modules can queue packets to indicated isochronous cycles. Although the cycle to queue a packet is deterministic by calculation, this module doesn't implement the calculation because it's useless for processing. In future, the cycle count is going to be printed with the other parameters for debugging. This commit is the preparation. The cycle count is computed by cycle unit, and correctly arranged to corresponding packets. The calculated count is used in later commit. Signed-off-by:

In callback function of isochronous context, u32 variable is passed for cycle count. The value of this variable comes from DMA descriptors of 1394 Open Host Controller Interface (1394 OHCI). In the specification, DMA descriptors transport lower 3 bits for second field and full cycle field in 16 bits field, therefore 16 bits of the u32 variable are available. The value for second is modulo 8, and the value for cycle is modulo 8,000. Currently, ALSA firewire-lib module don't use the value of the second field, because the value is useless to calculate presentation timestamp in IEC 61883-6. However, the value may be useful for debugging. In later commit, it will be printed with the other parameters for debugging. This commit makes this module to handle the whole cycle count including second. The value is calculated by cycle unit. The existed code is already written with ignoring the value of second, thus this commit causes no issues. Signed-off-by:

M-Audio Profire 610 has an unexpected value in version field of its config ROM, thus ALSA dice driver is not assigned to the model due to a mismatch of modalias.

There are many USB audio devices with buggy firmware that don't react with the sample rate reading properly. This often results in the flood of error messages and slowing down the operation. The sample rate read back is basically only for confirming the sample rate setup, and it's not critically important. As a compromise, in this patch, we stop the sample rate read back once when the device gives errors more than tolerance (twice, as of now). This should improve most of error cases while we still can catch the firmware bugginess. Signed-off-by:

For taking back the recent change of HDA HDMI fixes for i915 HSW/BDW. Signed-off-by: -
Takashi Iwai authored
The recent bug report suggests that BCLK setup for i915 HSW/BDW needs to be updated at each HDMI hotplug, not only at initialization and resume. That is, we need to update HSW_EM4 and HSW_EM5 registers at ELD notification, too. Otherwise the HDMI audio may be out of sync and played in a wrong pitch. However, the HDA codec driver has no access to the controller registers, and currently the code managing these registers is in hda_intel.c, i.e. local to the controller driver. For allowing the explicit BCLK update from the codec driver, as in this patch, the former haswell_set_bclk() in hda_intel.c is moved to hdac_i915.c and exposed as snd_hdac_i915_set_bclk(). This is called from both the HDA controller driver and intel_pin_eld_notify() in HDMI codec driver. Along with this change, snd_hdac_get_display_clk() gets dropped as it's no longer used.

This patch tries to address the still remaining issues in ALSA hrtimer driver: - Spurious use-after-free was detected in hrtimer callback - Incorrect rescheduling due to delayed start - WARN_ON() is triggered in hrtimer_forward() invoked in hrtimer callback The first issue happens only when the new timer is scheduled even while hrtimer is being closed. It's related with the second and third items; since ALSA timer core invokes hw.start callback during hrtimer interrupt, this may result in the explicit call of hrtimer_start(). Also, the similar problem is seen for the stop; ALSA timer core invokes hw.stop callback even in the hrtimer handler, too. Since we must not call the synced hrtimer_cancel() in such a context, it's just a hrtimer_try_to_cancel() call that doesn't properly work. Another culprit of the second and third items is the call of hrtimer_forward_now() before snd_timer_interrupt(). The timer->stick value may change during snd_timer_interrupt() call, but this possibility is ignored completely. For covering these subtle and messy issues, the following changes have been done in this patch: - A new flag, in_callback, is introduced in the private data to indicate that the hrtimer handler is being processed. - Both start and stop callbacks skip when called from (during) in_callback flag. - The hrtimer handler returns properly HRTIMER_RESTART and NORESTART depending on the running state now. - The hrtimer handler reprograms the expiry properly after snd_timer_interrupt() call, instead of before. - The close callback clears running flag and sets in_callback flag to block any further start/stop calls.
