Title: Nanokernel Footprint Measurement
|
||||
|
||||
Description:
|
||||
|
||||
This project is designed to characterize the memory requirements of a
|
||||
nanokernel-only image running on an Atom target.
|
||||
|
||||
|
||||
The project can be built using several configurations:
|
||||
|
||||
minimal (a "do nothing" image that has support for few kernel capabilities)
|
||||
-------
|
||||
- Background task is only task in system; no fibers are utilized.
|
||||
- Background task simply runs an endless loop that increments a global variable.
|
||||
- No system timer support.
|
||||
- ISR for the spurious interrupt handling is present.
|
||||
- IDT and stack memory sizes are very limited.
|
||||
|
||||
regular (a "typical" image that has support for some kernel capabilities)
|
||||
-------
|
||||
- As for "minimal" configuration, except as noted below.
|
||||
- Supports larger IDT and utilizes larger stacks.
|
||||
- A statically linked dummy ISR is present.
|
||||
- Background task also starts a fiber.
|
||||
- Fiber prints a message to the console via printk().
|
||||
- Supports system timer, along with NANO_TIMER objects.
|
||||
- Links in support for NANO_SEM objects.
|
||||
|
||||
maximal (a "complex" image that has support for many kernel capabilities)
|
||||
-------
|
||||
- As for "regular" configuration, except as noted below.
|
||||
- Supports full IDT and utilizes even larger stacks.
|
||||
- Background task dynamically links in the dummy ISR, rather than having
|
||||
it statically linked.
|
||||
- Fiber prints a message to the console via printf(), rather than printk().
|
||||
- Links in support for NANO_LIFO, NANO_STACK, and NANO_FIFO objects.
|
||||
- Adds floating point support (for x87 FPU, including SSE).
|
||||
|
||||
|
||||
--------------------------------------------------------------------------------
|
||||
|
||||
Building and Running Project:
|
||||
|
||||
This nanokernel project does not generate any output in the default case
|
||||
(TEST=min). In the regular case (TEST=reg) and the maximal case (TEST=max),
|
||||
it outputs to the console. It can be built and executed on QEMU as follows:
|
||||
|
||||
make TEST=min qemu (minimal configuration)
|
||||
|
||||
make TEST=reg qemu (regular configuration)
|
||||
|
||||
make TEST=max qemu (maximal configuration)
|
||||
|
||||
--------------------------------------------------------------------------------
|
||||
|
||||
Troubleshooting:
|
||||
|
||||
Problems caused by out-dated project information can be addressed by
|
||||
issuing one of the following commands then rebuilding the project:
|
||||
|
||||
make clean # discard results of previous builds
|
||||
# but keep existing configuration info
|
||||
or
|
||||
make pristine # discard results of previous builds
|
||||
# and restore pre-defined configuration info
|
||||
|
||||
--------------------------------------------------------------------------------
|
||||
|
||||
Sample Output:
|
||||
|
||||
The resulting image is bootable for all configurations, but produces different
|
||||
output in each case.
|
||||
|
||||
minimal
|
||||
-------
|
||||
This configuration does NOT produce any output. To observe its operation,
|
||||
invoke it using gdb and observe that:
|
||||
- main() increments "i" each time it loops
|
||||
- the kernel's timer ISR increments "nanoTicks" on a regular basis
|
||||
|
||||
regular
|
||||
-------
|
||||
This configuration prints the following message to the console:
|
||||
|
||||
Running regular nanokernel configuration
|
||||
|
||||
maximal
|
||||
-------
|
||||
This configuration prints the following message to the console:
|
||||
|
||||
Running maximal nanokernel configuration
|
||||
|
||||
--------------------------------------------------------------------------------
|
||||
|
||||
Additional notes:
|
||||
|
||||
Various host utilities (such as the Unix "size" utility) can be used to
|
||||
determine the footprint of the resulting zephyr.elf image.
