MPC8xx INIT_TASK_SIZE

Hi

Why is it not possibly to increase INIT_TASK_SIZE in schred.c and there by increase the kernel stack size?

Im running a heavy loaded RTLinux subsystem and the hole system (2.4.4 from Denx) go's down when I start a big program in Linux user-space.

Dear Jacob,

In schred.c? Do you mean include/linux/sched.h instead by any chance? Because that's the only place where INIT_TASK_SIZE is actually used.

Why do you think you can't increase it?

Um... you don;t want run RTL on a 8xx system; there are a couple of bugs which have never been fixed - and we (DENX) will not spend any further efforts on RTL.

Use RTAI instead, which will continue to be supported on 8xx and other PPC systems.

There are assumptions in the 8xx tlb miss handler that everything above 0x80000000 is kernel space.
