The last fallback of CORB/RIRB communication error recovery is to turn on the single command mode, and this last resort usually means that something is really screwed up. Instead of a normal dev_err(), show the error more clearly with dev_WARN() with the caller stack trace. Also, show the bus-reset fallback also as an error, too.

In current implementation of ALSA IEC 61883-1/6 packet streaming engine, 16 packets are handled in one interrupt of isochronous context of OHCI 1394. Overall packet processing runs for each. However, this is not better in a point to split the processing into several parts. This commit is an attempt to add intermediate representation for parameters required for the parts. Signed-off-by:

Some protocols don't use syt field of CIP header to represent presentation timestamp. For such protocol, ALSA IEC 61883-1/6 packet streaming engine uses a pointer into local variable for the value of syt to call data block processing layer. However, it can decide the value when initializing packet streaming layer. This commit adds 'syt_override' member for packet streaming layer. Signed-off-by:

Recent firmware for Fireworks board module have a quirk to start transmission of CIP with non-zero value for its data block counter. In current implementation of ALSA firewire stack, the quirk is handled by 'struct amdtp_stream.ctx_data.tx.first_dbc' with value 0x02. However, the value comes from reverse engineering. It's better to handle this quirk without the explicit value. In a process to parse CIP header, the quirk of data block counter affects decision of sequence index in sequence-multiplexed data channel; i.e. MIDI conformant data channel. In Fireworks, the index is decided by the number of data blocks from top of the same CIP, thus the value of data block counter is useless. This commit adds CIP_UNALIGHED_DBC flag and obsoletes the explicit value for this quirk. Signed-off-by:

AMD/ATI and Nvidia HDMI codec drivers didn't have the audio component binding like i915, but it worked only with the traditional HD-audio unsolicited event for the HDMI hotplug detection and the ELD read-up thereafter. This has been a problem in many ways: first of all, it goes through the hardware event transition (from GPU register write, HD-audio controller trigger, and finally to HD-audio unsolicited event handling), which is often unreliable and may miss some opportunities. Second, each unsol event handling and ELD read-up need the explicit power up / down when the codec is in the runtime suspend. Last but not least, which is the most important, the hotplug wakeup may be missed when the HD-audio controller is in runtime suspend. Especially the last point is a big problem due to the recent change relevant with vga_switcheroo that forcibly enables the runtime PM for AMD HDMI controllers. These issues are solved by introducing the audio component; the hotplug notification is done by a direct function callback, which is more accurate and reliable, and it can be processed without the actual hardware access, i.e. no runtime PM trigger is needed, and the HD-audio gets the event even if it's in runtime suspend. The same for ELD query, as it's read directly from the cached ELD bytes stored in the DRM driver, hence the whole hardware access can be skipped. So here it is: this patch implements the audio component binding with AMD/ATI and Nouveau DRM drivers. The biggest difference from i915 implementation is that this binding is fully optional and it can be enabled asynchronously on the fly. That is, the driver will switch from the HD-audio unsolicited event to the notify callback once when the DRM component gets bound. Similarly, when DRM driver gets unloaded, the HDMI event handling returns to the legacy mode, too. Also, another difference from i915 is that the new code registers the component in the codec driver, while i915 HDMI codec assumes the component binding was already done in the HD-audio controller driver. Hence the new code does need to de-register the component binding at the codec exit, too. Some other details: - The match component ops assumes that both VGA and HD-audio controller PCI entries belong to the same PCI bus, and only accepts such an entry. - The pin2port audio_ops is implemented with assumption of the fixed widget layout. For AMD, it's starting from 3, with step 2 (3, 5, 7, ...), while for Nvidia, it's starting from 4, with step 1 (4, 5, 6, ...) As of this patch, the corresponding component isn't implemented in DRM side, so this change alone won't give any benefit. By the following changes in DRM sides, the mission will be completed.

The HDMI jack handling reports the state change always via snd_jack_report() whenever hdmi_present_sense() is called, even if the state itself doesn't change from the previous time. This is mostly harmless but still a bit confusing to user-space. This patch reduces such spurious jack state changes and reports only when the state really changed. Also, as a minor optimization, avoid overwriting the pin ELD data when the state is identical. Reviewed-by:
