3	bool "Sound Open Firmware Support"
4	help
5	  This adds support for Sound Open Firmware (SOF). SOF is free and
6	  generic open source audio DSP firmware for multiple devices.
7	  Say Y if you have such a device that is supported by SOF.

19	  This adds support for PCI enumeration. This option is

30	  This adds support for ACPI enumeration. This option is required
31	  to enable Intel Broadwell/Baytrail/Cherrytrail devices.

33	  be used as default for platform-specific drivers.

74	help
75	  This option forces the use of a probe workqueue, which is only used
76	  when HDaudio is enabled due to module dependencies. Forcing this
77	  option is intended for debug only, but this should not add any
78	  functional issues in nominal cases.

87	help
88	  This adds support for a dummy/nocodec machine driver fallback
89	  option if no known codec is detected. This is typically only
90	  enabled for developers or devices where the sound card is
91	  controlled externally.
92	  This option is mutually exclusive with the Intel HDAudio support.
93	  Selecting it may have negative impacts and prevent e.g. microphone
94	  functionality from being enabled on Intel CoffeeLake and later
95	  platforms.
96	  Distributions should not select this option!
97	  Say Y if you need this nocodec fallback option.
98	  If unsure select "N".

100config SND_SOC_SOF_STRICT_ABI_CHECKS
101	bool "SOF strict ABI checks"
102	help
103	  This option enables strict ABI checks for firmware and topology
104	  files.
105	  When these files are more recent than the kernel, the kernel
106	  will handle the functionality it supports and may report errors
107	  during topology creation or run-time usage if new functionality
108	  is invoked.
109	  This option will stop topology creation and firmware load upfront.
110	  It is intended for SOF CI/releases and not for users or distros.
111	  Say Y if you want strict ABI checks for an SOF release.
112	  If you are not involved in SOF releases and CI development,
113	  select "N".

115config SND_SOC_SOF_DEBUG
116	bool "SOF debugging features"
117	help
118	  This option can be used to enable or disable individual SOF firmware
119	  and driver debugging options.

126	bool "SOF force nocodec Mode"
127	depends on SND_SOC_SOF_NOCODEC_SUPPORT
128	help
129	  This forces SOF to use dummy/nocodec as machine driver, even
130	  though there is a codec detected on the real platform. This is
131	  typically only enabled for developers for debug purposes, before
132	  codec/machine driver is ready, or to exclude the impact of those
133	  drivers.
134	  Say Y if you need this force nocodec mode option.
135	  If unsure select "N".
136
137config SND_SOC_SOF_DEBUG_XRUN_STOP
138	bool "SOF stop on XRUN"
139	help
140	  This option forces PCMs to stop on any XRUN event. This is useful to
141	  preserve any trace data and pipeline status prior to the XRUN.
142	  Say Y if you are debugging SOF FW pipeline XRUNs.
143	  If unsure select "N".
144
145config SND_SOC_SOF_DEBUG_VERBOSE_IPC
146	bool "SOF verbose IPC logs"
147	help
148	  This option enables more verbose IPC logs, with command types in
149	  human-readable form instead of just 32-bit hex dumps. This is useful
150	  if you are trying to debug IPC with the DSP firmware.
151	  If unsure select "N".
152
153config SND_SOC_SOF_DEBUG_FORCE_IPC_POSITION
154	bool "SOF force to use IPC for position update on SKL+"
155	help
156	  This option forces to handle stream position update IPCs and run PCM
157	  elapse to inform ALSA about that, on platforms (e.g. Intel SKL+) that
158	  with other approach (e.g. HDAC DPIB/posbuf) to elapse PCM.
159	  On platforms (e.g. Intel SKL-) where position update IPC is the only
160	  one choice, this setting won't impact anything.
161	  If you are trying to debug pointer update with position IPCs or where
162	  DPIB/posbuf is not ready, select "Y".
163	  If unsure select "N".
164
165config SND_SOC_SOF_DEBUG_ENABLE_DEBUGFS_CACHE
166	bool "SOF enable debugfs caching"
167	help
168	  This option enables caching of debugfs
169	  memory -> DSP resource (memory, register, etc)
170	  before the audio DSP is suspended. This will increase the suspend
171	  latency and therefore should be used for debug purposes only.
172	  Say Y if you want to enable caching the memory windows.
173	  If unsure, select "N".
174
175config SND_SOC_SOF_DEBUG_ENABLE_FIRMWARE_TRACE
176	bool "SOF enable firmware trace"
177	help
178	  The firmware trace can be enabled either at build-time with
179	  this option, or dynamically by setting flags in the SOF core
180	  module parameter (similar to dynamic debug).
181	  If unsure, select "N".
182
183config SND_SOC_SOF_DEBUG_IPC_FLOOD_TEST
184	bool "SOF enable IPC flood test"
185	help
186	  This option enables the IPC flood test which can be used to flood
187	  the DSP with test IPCs and gather stats about response times.
188	  Say Y if you want to enable IPC flood test.
189	  If unsure, select "N".
190
191config SND_SOC_SOF_DEBUG_RETAIN_DSP_CONTEXT
192	bool "SOF retain DSP context on any FW exceptions"
193	help
194	  This option keeps the DSP in D0 state so that firmware debug
195	  information can be retained and dumped to userspace.
196	  Say Y if you want to retain DSP context for FW exceptions.
197	  If unsure, select "N".

219	  When selected, the probe is handled in two steps, for example to
220	  avoid lockdeps if request_module is used in the probe.
