* The following obscurantism is a hack to reduce stack usage, maybe even a questionable performance

* optimization.
|
|
*
|
|
* rusEfi main processing happends on IRQ so PORT_INT_REQUIRED_STACK has to be pretty large. Problem
|
|
* is that PORT_INT_REQUIRED_STACK is included within each user thread stack, thus this large stack multiplies
|
|
* and this consumes a lot of valueable RAM. While forcing the comiler to inline helps to some degree,
|
|
* it would be even better not to waste stack on passing the parameter.
|
|
*
|
|
* In the firmware we are using 'extern *Engine' - in the firmware Engine is a signleton
|
|
*
|
|
* On the other hand, in order to have a meaningful unit test we are passing Engine * engine as a parameter
