Does anyone know what limitations there are on the stack size of an
interrupt service routine (ISR) in RT Linux 2.2?
The ISR is specified in the call to rtl_request_irq():
rtl_request_irq(irqN, isrFunc);
I'm using Red Hat Linux 6.1 with kernel 2.2.14-rtl2.2
on a 233 Mhz pentium.
For example, can I safely define my isrFunc as:
unsigned int
isrFunc(unsigned int irqN, struct pt_regs *regs)
{
...
f();
...
}
int f(void)
{
char anotherBigBuff[100000];
...
}
If there is some limit, how can the ISR find out what it is?
Can it be changed without having to recompile Linux/RTLinux?
For example, can it be changed dynamically in my RTLinux module?
Thanks in advance for your consideration!
