config HOST_PTABLE

bool

default n

config COMPILER_WORKAROUND_CACHE_ATTR

bool

default n

depends on XTENSA

help

Select this to activate use of functions instead of macros

to decide whether an address is cacheable or not.

There is a weird optimization bug with gcc10x and gcc8.1

(with -O2 flags) on IMX platforms. See PR #4605.

config COMPILER_INLINE_FUNCTION_OPTION

bool

default y if CAVS_VERSION_2_5 || ACE

default n

help

When enabled, -fno-inline-function option is not passed to compiler

config COLD_STORE_EXECUTE_DRAM

bool "Execute and use cold data and code in DRAM"

help

Non-performance critical data and code can be kept in DRAM to be

accessed and executed there without copying to SRAM. Select this

option to enable this feature to save SRAM and to speed up SRAM

copying of performance-critical data and code.

config COLD_STORE_EXECUTE_DEBUG

bool "Enable checks for cold code on hot paths"

help

This enables an assert_can_be_cold() check, which causes an exception

if called in the LL task context and assert() evaluation is enabled.

config FAST_GET

bool "Enable simple refcounting DRAM data copier"

help

Enable simple refcounting DRAM data copier for copying processing

module data from DRAM to SRAM when the data is needed and freeing

the SRAM when the data is not needed anymore. If multiple module

instances need the same chunk the same copy is used with reference

counting. Source is src/lib/fast-get.c. The option should be selected

on platforms, where __cold_rodata is supported.

config SOF_OS_LINUX_COMPAT_PRIORITY

bool "Prioritize backwards compatibility for old Linux kernels"

help

Build option to maintain maximal backwards compatibility with old

versions of Linux SOF driver. When this is not set, firmware may

require newer version of host, and/or use features that are not

available in stable Linux kernel trees.

config DEBUG

bool "Enable debug build"

default n

help

Select for debug build

config GDB_DEBUG

bool "GDB Stub"

default n

help

Select for GDB debugging

config DEBUG_MEMORY_USAGE_SCAN

bool "Memory usage scan"

default y

help

It enables memory usage scan at demand in runtime.

This feature does not affect standard memory operations,

especially allocation and deallocation.

config DEBUG_IPC_COUNTERS

bool "IPC counters"

depends on CAVS

depends on DEBUG

default n

help

Select for enabling tracing IPC counter in SRAM_REG mailbox

config DEBUG_IPC_TIMINGS

bool "Enable IPC message handling time logging"

depends on DEBUG

default n

help

Adds a logging after IPC handling before putting IPC reply

to send queue. The logging contains both the reply and the

original request message headers and the time that it took

to process the request in micro seconds. The value can be

used to collect statistics on changes in firmware response

times. This also disables the logging of the received

request on core 0 to avoid flooding the logs too much.

config SCHEDULE_LOG_CYCLE_STATISTICS

bool "Log cycles per tick statistics for each task separately"

default y

help

Log DSP cycle usage statistics about once per second (1ms *

1024) for each task separately. The printed data is task's

meta information, average number of cycles/tick, and maximum

number of cycles/tick during the previous 1024 tick period.

config PERFORMANCE_COUNTERS

bool "Performance counters"

default n

help

Enables tracing of simple performance measurements.

A basic use case is to measure number of platform & cpu clock ticks

passed between two checkpoints (init() and stamp()), for example

total time spent on running low latency scheduler tasks.

Platforms that gate cpu clock in wait-for-interrupt calls may also

use the stamp() macro periodically to find out how long the cpu

was in active/sleep state between the calls and estimate the cpu load.

config PERFORMANCE_COUNTERS_COMPONENT

bool "Use performance counters to track component execution"

default n

depends on PERFORMANCE_COUNTERS

help

Use performance counters to trace low-latency task execution.

This enables to observe average and peak execution times at

audio component level granularity.

Results are reported via logging subsystem.

config PERFORMANCE_COUNTERS_LL_TASKS

bool "Use performance counters to track LL task execution"

default n

depends on PERFORMANCE_COUNTERS

help

Use performance counters to trace low-latency task execution.

This enables to observe average and peak execution times at

task level granularity.

Results are reported via logging subsystem.

config DSP_RESIDENCY_COUNTERS

bool "DSP residency counters"

default n

help

Enables simple DSP residency counters in SRAM_REG mailbox.

R0, R1, R2 are abstract states which can be used differently

based on platform implementation.
