2022-01-26usb: gadget: f_uac2: allow changing interface name via configfsYunhao Tian4-1/+49
This adds "function_name" configfs entry to change string value of the iInterface field. This field will be shown in Windows' audio settings panel, so being able to change it is useful.

2022-01-26usb: gadget: f_uac2: Add suspend callbackPavel Hofman1-0/+9
When USB cable gets disconnected, the undergoing playback/capture stalls, without any notification to u_audio about the change. Experiments with a dwc2 gadget revealed that Suspend interrupt is thrown at cable disconnection, which the gadget framework translates to calling suspend callback of a function, if it is defined. Add the suspend callback to f_uac2 function, calling corresponding method of u_audio in order to stop the respective PCM streams and to notify subscribed clients at cable disconnection.

2022-01-26usb: gadget: u_audio: Rate ctl notifies about current srate (0=stopped)Pavel Hofman1-1/+27
The Playback/Capture ctl currently reports rate value set by USB control selector UAC2_CS_CONTROL_SAM_FREQ (fixed for UAC1). When the stops playback/capture, the reported value does not change. The gadget side has no information whether the host has started/stopped capture/playback. This patch sets the value reported by the respective rate ctl to zero when the host side has stopped playback/capture. Also, it calls snd_ctl_notify when start/stop occurs, so that a subscribed client can act appropriately. Tests have confirmed that USB hosts change UAC2_CS_CONTROL_SAM_FREQ before switching altsetting to activate playback/capture, resulting in correct order (params->c/p_srate is set to requested rate before u_audio_start_capture/playback is called). The gadget rate notifications are used by user-space audio gadget controller gaudio_ctl https://github.com/pavhofman/gaudio_ctl.

The latest merge of the tracing tree sorts the mcount table at build time. But s390 appears to do things differently (like always) and replaces the sorted table back to the original unsorted one. As the ftrace algorithm depends on it being sorted, bad things happen when it is not, and s390 experienced those bad things.

2022-01-23ftrace: Fix assuming build time sort works for s390Steven Rostedt (Google)2-3/+10
To speed up the boot process, as mcount_loc needs to be sorted for ftrace to work properly, sorting it at build time is more efficient than boot up and can save milliseconds of time. Unfortunately, this change broke s390 as it will modify the mcount_loc location after the sorting takes place and will put back the unsorted locations. Since the sorting is skipped at boot up if it is believed that it was sorted at run time, ftrace can crash as its algorithms are dependent on the list being sorted. Add a new config BUILDTIME_MCOUNT_SORT that is set when BUILDTIME_TABLE_SORT but not if S390 is set. Use this config to determine if sorting should take place at boot up.

2022-01-22perf evsel: Override attr->sample_period for non-libpfm4 eventsGerman Gomez1-8/+17
A previous patch preventing "attr->sample_period" values from being overridden in pfm events changed a related behaviour in arm-spe. Before said patch: perf record -c 10000 -e arm_spe_0// -- sleep 1 Would yield an SPE event with period=10000. After the patch, the period in "-c 10000" was being ignored because the arm-spe code initializes sample_period to a non-zero value. This patch restores the previous behaviour for non-libpfm4 events.
