A larger buffer (e.g. 2048) is preferred31 for systems using PulseAudio. The default 64 is chosen just32 for compatibility reasons.33 On x86 systems, the default is zero as S/G allocation works34 and no preallocation is needed in most cases.35 36 Note that the pre-allocation size can be changed dynamically37 via a proc file (/proc/asound/card*/pcm*/sub*/prealloc), too.38 39config SND_INTEL_NHLT40 bool41 # this config should be selected only for Intel ACPI platforms.42 # A fallback is provided so that the code compiles in all cases.43 44config SND_INTEL_DSP_CONFIG45 tristate46 select ACPI_NHLT if ACPI47 select SND_INTEL_NHLT if ACPI48 select SND_INTEL_SOUNDWIRE_ACPI if ACPI49 # this config should be selected only for Intel DSP platforms.50 # A fallback is provided so that the code compiles in all cases.51 52config SND_INTEL_SOUNDWIRE_ACPI53 tristate54 55config SND_INTEL_BYT_PREFER_SOF56 bool "Prefer SOF driver over SST on BY/CHT platforms"57 depends on SND_SST_ATOM_HIFI2_PLATFORM_ACPI && SND_SOC_SOF_BAYTRAIL58 default n59 help60 The kernel has 2 drivers for the Low Power Engine audio-block on61 Bay- and Cherry-Trail SoCs.
