Hi. Does anyone know what exception 0xe is?? rtl_debug is catching
it. It comes about when I increase the amount of memory in my RT
application. I am allocating an array that is 8 MB. This exception is not
generated if I used say 1K of RAM for the array. My system is a dual
P-II, running 2.4.1 linux and rtlinux-3.0.
This brings up a larger question in the context of memory
mangement, which is how do the TLBs operate under RTL?? Meaning, if a TLB
miss is generated does RTL catch that or does the MMU handle as it would
for regular Linux. I know for example that x86 has hardware managed TLBs
where the MIPS processors are software managed (i.e., trap to the OS).
Any help would be most appreciated.
Thanks,
Chris
