MyNC kernel
MyNC's kernel-mode code includes a modified version of the Linux kernel and several kernel modules from "mykernel" subdirectory in the repository.
Kernel patch: patch-2.6.19-mync_07-01-28Here is some information about the kernel patch: linux-2.6.19-mync patch description
Here is the list of MyNC's kernel modules:| ncb_timer | - | central module, contains character device operations, timer interrupt handler, initializes other modules. | |
| stepper | - | contains code that handles stepper motors: acceleration etc. | |
| timer_lapic | - | timer module utilizing Local APIC timer of the bootstrap processor. | |
| timer_i8254 | - | timer module utilizing good old Intel 8254 timer. | |
| timer_nonrt | - | non-realtime timer module that uses kernel timer API. It allows to debug MyNC while running a non-patched kernel. | |
| mfirst | - | this is actually a driver for a specific dedicated I/O board. It can serve as an example of how to connect MyNC with real hardware. | |
| mspk | - | a module that imitates motor noise using PC speaker. It provides evidence of some work being performed in the absence of real motors. |
Only one timer module can be loaded at a time because they contain duplicate symbols. timer_lapic module is meant to be used with -mync kernels. timer_i8254 is legacy and can be used only with old 2.6.5-ds kernel patch which you can find here.
