menuconfig CONSOLE
bool "Console drivers"
if CONSOLE
config CONSOLE_INPUT_MAX_LINE_LEN
int "Console maximum input line length"
default 128
help
This option can be used to modify the maximum length a console input
can be.
config CONSOLE_HAS_DRIVER
bool
help
This is an option to be enabled by console drivers to signal
that some kind of console exists.
config CONSOLE_HANDLER
bool "Console input handler"
depends on UART_CONSOLE && SERIAL_SUPPORT_INTERRUPT
select UART_INTERRUPT_DRIVEN
help
This option enables console input handler allowing to write simple
interaction between serial console and the OS.
config CONSOLE_INIT_PRIORITY
int "Console init priority"
default 60 if UART_CONSOLE || XTENSA_SIM_CONSOLE
default KERNEL_INIT_PRIORITY_DEFAULT
help
Console driver device initialization priority.
config UART_CONSOLE
bool "Use UART for console"
depends on SERIAL && SERIAL_HAS_DRIVER
select CONSOLE_HAS_DRIVER
help
Enable this option to use one UART for console.
config UART_CONSOLE_DEBUG_SERVER_HOOKS
bool "Debug server hooks in debug console"
depends on UART_CONSOLE
help
This option allows a debug server agent such as GDB to take over the
handling of traffic that goes through the console logic. The debug
server looks at characters received and decides to handle them itself if
they are some sort of control characters, or let the regular console
code handle them if they are of no special significance to it.
config UART_CONSOLE_MCUMGR
bool "UART console mcumgr passthrough"
depends on UART_CONSOLE
help
Enables the UART console to receive mcumgr frames for image upgrade
and device management. When enabled, the UART console does not
process mcumgr frames, but it hands them up to a higher level module
(e.g., the shell). If unset, incoming mcumgr frames are dropped.
config UART_CONSOLE_INPUT_EXPIRED
bool "Support for UART console input expired mechanism"
default y
depends on UART_CONSOLE && PM
help
This option allows a notification to the power management module that
the module for UART console is in use now. If the interval of console
module doesn't receive any input message exceeds expired timeout, such
as UART_CONSOLE_INPUT_EXPIRED_TIMEOUT, the power management module is
allowed to enter sleep/deep sleep state and turn off the clock of UART
console module. This mechanism gives a window in which the users can
organize input message if CONFIG_PM is enabled.
config UART_CONSOLE_INPUT_EXPIRED_TIMEOUT
int "Fixed amount of time to keep the UART console in use flag true"
default 15000
depends on UART_CONSOLE_INPUT_EXPIRED
help
Fixed amount of time which unit is milliseconds to keep the UART
console in use flag true.
config JAILHOUSE_DEBUG_CONSOLE
bool "Use JAILHOUSE_DEBUG console"
select CONSOLE_HAS_DRIVER
depends on ARM64
help
Emit console messages to a jailhouse hypervisor debug console.
Useful in board bring-up if there aren't any working serial
drivers.

DT_CHOSEN_Z_RAM_CONSOLE := zephyr,ram-console
config RAM_CONSOLE
bool "Use RAM console"
select CONSOLE_HAS_DRIVER
select RAM_CONSOLE_BUFFER_SECTION if $(dt_chosen_enabled,$(DT_CHOSEN_Z_RAM_CONSOLE))
help
Emit console messages to a RAM buffer "ram_console" which can
be examined at runtime with a debugger. Useful in board bring-up
if there aren't any working serial drivers.
config RAM_CONSOLE_BUFFER_SECTION
bool "Use dedicated section as RAM console buffer"
depends on RAM_CONSOLE && $(dt_chosen_enabled,$(DT_CHOSEN_Z_RAM_CONSOLE))
select KERNEL_DIRECT_MAP if MMU
help
Use a dedicated section as the RAM console buffer, whose address is
known before build so that the console output messages can be easily
examined by a debugger or software tool from a parallel-running OS.
config RAM_CONSOLE_BUFFER_SIZE
int "Ram Console buffer size"
default $(dt_chosen_reg_size_int,$(DT_CHOSEN_Z_RAM_CONSOLE)) if RAM_CONSOLE_BUFFER_SECTION
default 1024
depends on RAM_CONSOLE
help
Total size of the RAM console buffer, to ensure it's always
NULL-terminated leave one byte unused, the actual length is
one byte less. Messages will wrap around if the actual length
is exceeded.
config RTT_CONSOLE
bool "Use RTT console"
depends on USE_SEGGER_RTT
select CONSOLE_HAS_DRIVER
help
Emit console messages to a RAM buffer that is then read by the
Segger J-Link software and displayed on a computer in real-time.
Requires support for Segger J-Link on the companion IC onboard.
if RTT_CONSOLE
config RTT_TX_RETRY_CNT
int "Number of TX retries"
default 2
help
Number of TX retries before dropping the byte and assuming that
RTT session is inactive.
config RTT_TX_RETRY_DELAY_MS
int "Delay between TX retries in milliseconds"
default 2
help
Sleep period between TX retry attempts. During RTT session, host pulls data
periodically. Period starts from 1-2 milliseconds and can be increased
if traffic on RTT increases (also from host to device). In case of
heavy traffic data can be lost and it may be necessary to increase
delay or number of retries.
config RTT_TX_RETRY_IN_INTERRUPT
bool "Busy wait in the interrupt context for TX retry"
help
If enabled RTT console will busy wait between TX retries when console
assumes that RTT session is active. In case of heavy traffic data can
be lost and it may be necessary to increase delay or number of
retries.

config IPM_CONSOLE_SENDER
bool "Inter-processor Mailbox console sender"
select CONSOLE_HAS_DRIVER
help
Enable the sending side of IPM console
config IPM_CONSOLE_RECEIVER
bool "Inter-processor Mailbox console receiver"

Enable the receiving side of IPM console
config IPM_CONSOLE_STACK_SIZE
int "Stack size for IPM console receiver thread"
depends on IPM_CONSOLE_RECEIVER
default 2048 if COVERAGE_GCOV
default 512
help
Each instance of the IPM console receiver driver creates a worker
thread to print out incoming messages from the remote CPU. Specify the
stack size for these threads here.
config IPM_CONSOLE
bool "Inter-processor Mailbox console"
depends on IPM
select CONSOLE_HAS_DRIVER
help
Enable console over Inter-processor Mailbox.
config IPM_CONSOLE_LINE_BUF_LEN
int "IPM console line buffer length"

depends on IPM_CONSOLE
help
IPM console line buffer length specify amount of the buffer
where characters are stored before sending the whole line.
config UART_MCUMGR
bool "Mcumgr UART driver"
select UART_INTERRUPT_DRIVEN
help
Enable the mcumgr UART driver. This driver allows the application to
communicate over UART using the mcumgr protocol for image upgrade and
device management. The driver doesn't inspect received data (as
contrary to console UART driver) and all aspects of received protocol
data are handled by an application provided callback.
if UART_MCUMGR
config UART_MCUMGR_RX_BUF_SIZE
int "Size of receive buffer for mcumgr fragments received over UART, in bytes"
default 128
help
Specifies the size of the mcumgr UART receive buffer, in bytes. This
value must be large enough to accommodate any line sent by an mcumgr
client.
config UART_MCUMGR_RX_BUF_COUNT
int "Number of receive buffers for mcumgr fragments received over UART"
default 2
help
Specifies the number of the mcumgr UART receive buffers. Receive
buffers hold received mcumgr fragments prior to reassembly. This
setting's value must satisfy the following relation:
UART_MCUMGR_RX_BUF_COUNT * UART_MCUMGR_RX_BUF_SIZE >=
MCUMGR_TRANSPORT_UART_MTU
