config WAITI_DELAY

bool

default n

help

LX6 Xtensa platforms may require additional delay to flush loads

and stores before entering WAITI.

config HOST_PTABLE

bool

default n

config BOOT_LOADER

bool

default n

config HAVE_RESET_VECTOR_ROM

bool

default n

help

Select if your platform has the reset vector

in ROM.

config IRQ_MAP

bool

default n

config DMA_GW

bool

default n

config MEM_WND

bool

default n

config INTEL_IOMUX

bool

default n

config HW_LLI

bool

default n

help

Hardware linked list is the DW-DMA feature, which allows

to automatically reload the next programmed linked list

item from memory without stopping the transfer. Without

it the transfer stops after every lli read and FW needs

to manually setup the next transfer.

Any platforms with hardware linked list support

should set this.

config DW_DMA_AGGREGATED_IRQ

bool

default n

help

Some platforms cannot register interrupt per DW-DMA channel

and have the possibility only to register interrupts per

DMA controller, which require manual handling of aggregated

irq.

Any platforms with DW-DMA aggregated interrupts support

should set this.

config DMA_SUSPEND_DRAIN

bool

default n

help

Some platforms cannot just simple disable DMA

channel during the transfer, because it will

hang the whole DMA controller. Instead we can

suspend the channel and drain the FIFO in order

to stop the channel as soon as possible.

Any platforms without the ability to disable

the DMA channel right away should set this.

config DMA_FIFO_PARTITION

bool

default n

help

Some platforms require to manually set DMA

FIFO partitions before starting any transfer.

Any platforms without automatic FIFO partitions

should set this.

config INTERRUPT_LEVEL_1

bool

default n

help

Select if the platform supports any interrupts of level 1.

Disabling this option allows for less memory consumption.

config INTERRUPT_LEVEL_2

bool

default n

help

Select if the platform supports any interrupts of level 2.

Disabling this option allows for less memory consumption.

config INTERRUPT_LEVEL_3

bool

default n

help

Select if the platform supports any interrupts of level 3.

Disabling this option allows for less memory consumption.

config INTERRUPT_LEVEL_4

bool

default n

help

Select if the platform supports any interrupts of level 4.

Disabling this option allows for less memory consumption.

config INTERRUPT_LEVEL_5

bool

default n

help

Select if the platform supports any interrupts of level 5.

Disabling this option allows for less memory consumption.

config IDC_TASK_BUDGET

int "Cycles budget for IDC task"

depends on MULTICORE

default 8000

help

Cycles budget for IDC task per systick (see config SYSTICK).

prompt "Optimization"

default OPTIMIZE_FOR_PERFORMANCE

help

Controls how compiler should optimize binary.

This config should affect only compiler settings and is

not meant to be used for conditional compilation of code.

config OPTIMIZE_FOR_PERFORMANCE

bool "Optimize for performance"

help

Apply compiler optimizations prioritizing performance.

It means -O2 for GCC or equivalent for other compilers.

config OPTIMIZE_FOR_SIZE

bool "Optimize for size"

help

Apply compiler optimizations prioritizing binary size.

It means -Os for GCC or equivalent for other compilers.

config OPTIMIZE_FOR_DEBUG

bool "Optimize for debug"

help

Apply compiler optimizations prioritizing debugging experience.

It means -Og for GCC or equivalent for other compilers.

config OPTIMIZE_FOR_NONE

bool "Don't optimize"

help

Apply no compiler optimizations.

It means -O0 for GCC or equivalent for other compilers.

menu "Debug"

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_HEAP

bool "Heap debug"

default n

help

Select for enable heap alloc debugging

config DEBUG_BLOCK_FREE

bool "Blocks freeing debug"

default n

help

It enables checking if free was called multiple times on

already freed block of memory. Enabling this feature increases

number of memory writes and reads, due to checks for memory patterns

that may be performed on allocation and deallocation.

config DEBUG_LOCKS

bool "Spinlock debug"

default n

help

It adds additional information to the spinlocks about

the current user of the lock. Also executes panic

on deadlock.

config DEBUG_LOCKS_VERBOSE

bool "Spinlock verbose debug"

depends on DEBUG_LOCKS

default n

help

In addition to DEBUG_LOCKS it also adds spinlock traces

every time the lock is acquired.

config BUILD_VM_ROM

bool "Build VM ROM"

default n

help

Select if you want to build VM ROM

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 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 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.
