| * cpu_asm.S: This patch was co-developed with Eric Norum <eric.norum@usask.ca>. It closes a one instruction window on some m68k CPU cores. It fixes symptoms seen as: 1) No more `interrupt handler invoked twice for a single interrupt'. 2) No more `lockup when mc68360 CPM and PIT interrupts are at different levels'. It does insert a little more overhead on machines without hardware interrupt stacks but correctness has a price. | |||||

| * rtems/score/cpu.h: Added _CPU_Initialize_vectors(). * cpu_asm.S: Modify to properly dereference _ISR_Vector_table now that it is dynamically allocated. | |||||

| I found that my 68040/68360 test programs would not run even after I fixed the `wrong BSP' problem. It seems that there's a bug in the interrupt handling code for processors with hardware interrupt stacks (e.g. 68040). The wrong status register was getting pushed on the stack for the `return from exception' to call _ISR__Dispatch. This ended up making the context switch code run on the interrupt stack, so interrupt-driven context switches would always fail. I guess that no one has tried running any of the RTEMS-4.0 snapshots on a 68040 machine! Anyhow, here are the patches for 1) gen68360.cfg --- to fix the `wrong-BSP' problem. 2) m68k/cpu_asm.s --- to fix the hardware interrupt stack problem. With these patches in place, the network demo programs run on my 68040/68360 system. The paranoia program runs with no failures, defects nor flaws. | |||||

| 1997-07-10 | Strip the trace bit from the SR register when dispatching a thread when | Joel Sherrill | 1 | -3/+5 | |
