| [pok-devel] Trouble running examples/partition-scheduling on Qemu-emulated PowerPC/Prep |

Hi list,
I have been playing with POK for quite a while now and still cannot
manage to get examples/partition-scheduling working. I am trying to run
it under Qemu as a PowerPC/Prep emulator. From what gdb tells me,
pok_boot is executed and then returns into _pok_reset. From there, I
have lost the execution path to catch it again (via a breakpoint) in
pok_arch_rfi. When the rfi execution at the end of it is executed,
nothing happens, the Qemu process eats up 100% of the CPU core time.
Ctrl-C'ing leaves me executing reserved_2F00 (which seems to explain
Qemu becoming CPU-hungry).
Would you have any clues ?
My environment is the following:
- Windows XP 32Bit
- cygwin 1.5.25
+ GNU make 2.80
+ perl 5.8.8
- Ocarina 2.0w (r7317)
- Adacore toolchain for PowerPC
+ GCC 4.5.2
+ Binutils 2.20
+ Qemu 0.14.0
To make the example compile, I had to patch the build system in the
following way. Note that the removal of the ``(dist)clean'' target here
and there is just meant to avoid complete recompilation each time I
adjusted a quote.
