config IPM_CALLBACK_ASYNC
bool "Deliver callbacks asynchronously"
default y if IPM_CAVS_HOST
help
When selected, the driver supports "asynchronous" command
delivery. Commands will stay active after the ISR returns,
until the application expressly "completes" the command
later.
config IPM_CAVS_HOST
bool "cAVS DSP/host communication"
select INTEL_ADSP_IPC
help
Driver for host/DSP communication on intel_adsp devices
if IPM_CAVS_HOST
config IPM_CAVS_HOST_INBOX_OFFSET
hex "Byte offset of cAVS inbox window"
depends on INTEL_ADSP_IPC
default 0x6000
help
Location of the host-writable inbox window within the
HP_SRAM_RESERVE region. This location must be synchronized
with host driver and SOF source code (must match
SRAM_INBOX_BASE). Be careful.
config IPM_CAVS_HOST_OUTBOX_OFFSET
hex "Byte offset of cAVS outbox memory"
depends on INTEL_ADSP_IPC
default 0x1000
help
Location of the "outbox" region for SOF IPC3/4 message
within the pre-existing window 0 (this is not the same as
the HP_SRAM_RESERVE region used for INBOX_OFFSET). This
location must be synchronized with host driver and SOF
source code (where it must equal SRAM_SW_REG_SIZE). Be
careful.
config IPM_CAVS_HOST_REGWORD
bool "Store first 4 bytes in IPC register"
depends on INTEL_ADSP_IPC
help
Protocol variant. When true, the first four bytes of a
message are passed in the cAVS IDR/TDR register pair instead
of in the SRAM window. Only available on cAVS 1.8+.
