Updating nano kernel functions to follow a consistent naming convention.
Part of that process is the removal of camelCase naming conventions for the
preferred_underscore_method.
Change accomplished with the following script:
#!/bin/bash
echo "Searching for ${1} to replace with ${2}"
find . -type f \( -iname \*.c -o -iname \*.h -o -iname \*.s \) \
-not \( -path host/src/genIdt -prune \) \ \
-not \( -path host/src/gen_tables -prune \) \
-print | xargs sed -i "s/"${1}"/"${2}"/g"

config BOOT_BANNER
|
|
bool
|
|
prompt "Boot banner"
|
|
default n
|
|
select PRINTK
|
|
help
|
|
This option outputs a banner to the console device during boot up.
|
|
|
|
config WORKLOAD_MONITOR
|
|
bool
|
|
prompt "Workload monitoring [EXPERIMENTAL]"
|
|
default n
|
|
depends on MICROKERNEL
|
|
help
|
|
This option instructs the kernel to record the percentage of time
|
|
the system is doing useful work (i.e. is not idle).
|
|
|
|
config TASK_MONITOR
|
|
bool
|
|
prompt "Task monitoring [EXPERIMENTAL]"
|
|
default n
|
|
depends on MICROKERNEL
|
|
help
|
|
This option instructs the kernel to record significant task
|
|
activities. These can include: task switches, task state changes,
|
|
kernel service requests, and the signalling of events.
|
|
|
|
config TASK_MONITOR_CAPACITY
|
|
int
|
|
prompt "Trace buffer capacity (# of entries)"
|
|
default 300
|
|
depends on TASK_MONITOR
|
|
help
|
|
This option specifies the number of entries in the task monitor's
|
|
trace buffer. Each entry requires 12 bytes.
|
|
|
|
config TASK_MONITOR_MASK
|
|
int
|
|
prompt "Trace buffer mask"
|
|
default 15
|
|
depends on TASK_MONITOR
|
|
help
|
|
This option specifies which task execution activities are captured
|
|
in the task monitor's trace buffer. The following values can be
|
|
OR-ed together to form the mask:
|
|
1 (MON_TSWAP): task switch
|
|
2 (MON_STATE): task state change
|
|
4 (MON_KSERV): task execution of kernel APIs
|
|
8 (MON_EVENT): task event signalled
|
|
|
|
config OBJECT_MONITOR
|
|
bool
|
|
prompt "Kernel object monitoring [EXPERIMENTAL]"
|
|
default n
|
|
depends on MICROKERNEL
|
|
help
|
|
This option instructs the kernel to record statistics about
|
|
microkernel object usage.
|
|
|
|
config INIT_STACKS
|
|
bool
|
|
prompt "Initialize stack areas"
|
|
default n
|
|
help
|
|
This option instructs the kernel to initialize stack areas with a
|
|
known value (0xaa) before they are first used, so that the high
|
|
water mark can be easily determined. This applies to the stack areas
|
|
for both tasks and fibers, as well as for the K_swapper's command
|
|
stack.
|
|
|
|
config INT_LATENCY_BENCHMARK
|
|
bool
|
|
prompt "Interrupt latency metrics [EXPERIMENTAL]"
|
|
default n
|
|
help
|
|
This option enables the tracking of interrupt latency metrics;
|
|
the exact set of metrics being tracked is BSP-dependent.
|
|
|
|
Tracking begins when int_latency_init() is invoked by an application.
|
|
The metrics are displayed (and a new sampling interval is started)
|
|
each time intLatencyShow() is called thereafter.
|
|
|
|
config BOOT_TIME_MEASUREMENT
|
|
bool
|
|
prompt "Boot time measurements [EXPERIMENTAL]"
|
|
default n
|
|
help
|
|
This option enables the recording of timestamps during system start
|
|
up. The global variable __start_tsc records the time VxMicro begins
|
|
executing, while __main_tsc records when main() begins executing,
|
|
and __idle_tsc records when the CPU becomes idle. All values are
|
|
recorded in terms of CPU clock cycles since system reset.
|
|
|
|
config HOST_TOOLS_SUPPORT
|
|
bool
|
|
prompt "Host tools support [EXPERIMENTAL]"
|
|
default n
|
|
help
|
|
This option allows the kernel to interact with VxMicro host tools.
|
|
These tools allow users to monitor the behavior of the target system,
|
|
as well to debug it.
