70	bool "SOF nocodec mode support"
71	help
72	  This adds support for a dummy/nocodec machine driver fallback
73	  option if no known codec is detected. This is typically only
74	  enabled for developers or devices where the sound card is
75	  controlled externally
76	  This option is mutually exclusive with the Intel HDAudio support,
77	  selecting it may have negative impacts and prevent e.g. microphone
78	  functionality from being enabled on Intel CoffeeLake and later
79	  platforms.
80	  Distributions should not select this option!
81	  Say Y if you need this nocodec fallback option
82	  If unsure select "N".
83
84config SND_SOC_SOF_STRICT_ABI_CHECKS
85	bool "SOF strict ABI checks"
86	help
87	  This option enables strict ABI checks for firmware and topology
88	  files.
89	  When these files are more recent than the kernel, the kernel
90	  will handle the functionality it supports and may report errors
91	  during topology creation or run-time usage if new functionality
92	  is invoked.
93	  This option will stop topology creation and firmware load upfront.
94	  It is intended for SOF CI/releases and not for users or distros.
95	  Say Y if you want strict ABI checks for an SOF release
96	  If you are not involved in SOF releases and CI development
97	  select "N".
98
99config SND_SOC_SOF_DEBUG
100	bool "SOF debugging features"
101	help
102	  This option can be used to enable or disable individual SOF firmware
103	  and driver debugging options.

112	help
113	  This forces SOF to use dummy/nocodec as machine driver, even
114	  though there is a codec detected on the real platform. This is
115	  typically only enabled for developers for debug purposes, before
116	  codec/machine driver is ready, or to exclude the impact of those
117	  drivers
118	  Say Y if you need this force nocodec mode option
119	  If unsure select "N".

121config SND_SOC_SOF_DEBUG_XRUN_STOP
122	bool "SOF stop on XRUN"
123	help
124	  This option forces PCMs to stop on any XRUN event. This is useful to
125	  preserve any trace data ond pipeline status prior to the XRUN.
126	  Say Y if you are debugging SOF FW pipeline XRUNs.
127	  If unsure select "N".
128
129config SND_SOC_SOF_DEBUG_VERBOSE_IPC
130	bool "SOF verbose IPC logs"
131	help
132	  This option enables more verbose IPC logs, with command types in
133	  human-readable form instead of just 32-bit hex dumps. This is useful
134	  if you are trying to debug IPC with the DSP firmware.
135	  If unsure select "N".
136
137config SND_SOC_SOF_DEBUG_FORCE_IPC_POSITION
138	bool "SOF force to use IPC for position update on SKL+"
139	help
140	  This option force to handle stream position update IPCs and run pcm
141	  elapse to inform ALSA about that, on platforms (e.g. Intel SKL+) that
142	  with other approach (e.g. HDAC DPIB/posbuf) to elapse PCM.
143	  On platforms (e.g. Intel SKL-) where position update IPC is the only
144	  one choice, this setting won't impact anything.
145	  if you are trying to debug pointer update with position IPCs or where
146	  DPIB/posbuf is not ready, select "Y".
147	  If unsure select "N".
148
149config SND_SOC_SOF_DEBUG_ENABLE_DEBUGFS_CACHE
150	bool "SOF enable debugfs caching"
151	help
152	  This option enables caching of debugfs
153	  memory -> DSP resource (memory, register, etc)
154	  before the audio DSP is suspended. This will increase the suspend
155	  latency and therefore should be used for debug purposes only.
156	  Say Y if you want to enable caching the memory windows.
157	  If unsure, select "N".
158
159config SND_SOC_SOF_DEBUG_ENABLE_FIRMWARE_TRACE
160	bool "SOF enable firmware trace"
161	help
162	  The firmware trace can be enabled either at build-time with
163	  this option, or dynamically by setting flags in the SOF core
164	  module parameter (similar to dynamic debug)
165	  If unsure, select "N".
166
167config SND_SOC_SOF_DEBUG_IPC_FLOOD_TEST
168	bool "SOF enable IPC flood test"
169	help
170	  This option enables the IPC flood test which can be used to flood
171	  the DSP with test IPCs and gather stats about response times.
172	  Say Y if you want to enable IPC flood test.
173	  If unsure, select "N".
174
175config SND_SOC_SOF_DEBUG_RETAIN_DSP_CONTEXT
176	bool "SOF retain DSP context on any FW exceptions"
177	help
178	  This option keeps the DSP in D0 state so that firmware debug
179	  information can be retained and dumped to userspace.
180	  Say Y if you want to retain DSP context for FW exceptions.
181	  If unsure, select "N".
