The System Driver

The System Driver

The second configurable component is the RTFiles-32 system driver. The system driver can be modified without recompiling other parts of RTFiles-32. Users who do not own the RTFiles-32 source code can still modify the system driver.

The system driver's API is defined in file Include\Rtfsys.h. This file should not be modified to port RTFiles-32. It declares a number of platform dependent functions which must be implemented by the system driver. The functionality covered includes:

Time and date
Error handling
Mutex and semaphore handling
Interrupt handler installation
TLS (Task Local Storage) management
PCI config space access
Physical memory management

Further information about the system driver's API is contained as comments in file Include\Rtfsys.h which must be read and understood before it is attempted to port RTFiles-32. Note that files Driver\Rtf32\Sysrtk32.c and Driver\Rtf32\Sysrtt32.c contain two complete RTFiles-32 system driver implementations for On Time RTOS-32 with or without RTKernel-32. Use these files as templates for custom system drivers.
