config PLATFORM_EC_CONSOLE_CHANNEL
bool "Console channels"
depends on CONSOLE
default y
help
Make it possible for console to be output to different channels that
can be turned on and off. Channels are organized by functional area
such as "charger", "motionsense", "usbpd" and others.
This is useful as a developer convenience when the console is crowded
with messages, to make it easier to use the interactive console.
The `chan` console command with no arguments shows all available
channels.
FAFT and servod also use this feature.
Boards may #undef this to reduce image size.
# Adjusted to the account for the build_info[] string (about 160 bytes) plus
# the image type (about 16 bytes).
# printed by the banner.
config SHELL_PRINTF_BUFF_SIZE

# Some boards may need to increase the size, depending on the amount of output
config SHELL_BACKEND_SERIAL_TX_RING_BUFFER_SIZE

config PLATFORM_EC_ISR_CONSOLE_OUTPUT
bool "Log in ISRs"
depends on CONSOLE
default y
help
If enabled, allowing console output when in interrupt service routines
via printk. If disabled, silently drop these messages.
Console output via printk is unbuffered, so console output when in ISRs
should be avoided if possible - larger amounts of output will prevent
the EC from timely interrupt servicing.
menuconfig PLATFORM_EC_HOSTCMD_CONSOLE
bool "Console Host Command"
depends on PLATFORM_EC_HOSTCMD
default y
help
Enable the EC_CMD_CONSOLE_SNAPSHOT and EC_CMD_CONSOLE_READ
host commands, used for reading the EC console from the AP.
if PLATFORM_EC_HOSTCMD_CONSOLE
config PLATFORM_EC_HOSTCMD_CONSOLE_BUF_SIZE
int "Console buffer size"
default 4096
help
The EC will use a circular buffer to store bytes outputted
to the console for the AP to read. This changes the maximal
number of bytes from the console output which can be saved.
Choosing a power-of-two for this value is optimal, as
modular arithmetic is used.
endif # PLATFORM_EC_HOSTCMD_CONSOLE
menuconfig PLATFORM_EC_CONSOLE_DEBUG
bool "Console Debug"
depends on CONSOLE
default n
help
Write all zephyr_print() messages to printk() also. Not recommended
outside of tests.
config PLATFORM_EC_LOG_BACKEND_CONSOLE_BUFFER
bool "Logging backend for the console buffer"
depends on PLATFORM_EC_HOSTCMD_CONSOLE
depends on !LOG_MODE_MINIMAL
select LOG_OUTPUT
help
Enable the logging backend for the console buffer.
This will copy messages sent to the zephyr logging subsystem
to the EC console buffer. This allows the AP to access the
log messages with the console host command.
config PLATFORM_EC_LOG_BACKEND_CONSOLE_BUFFER_TMP_BUF_SIZE
int "Size of temporary buffer used by console buffer logging backend"
default 128 if LOG_MODE_DEFERRED
default 1
depends on PLATFORM_EC_LOG_BACKEND_CONSOLE_BUFFER
help
The size of the temporary buffer used by the console buffer backend.
The logging subsystem will buffer up to this many bytes before calling
the backend in deferred logging mode. Ideally this will be large
enough to fit an entire log line.
