Hi all: In my Hurd SMP project, I need help to solve many problems during the boot with ncpus != 2. https://github.com/AlmuHS/GNUMach_SMP/issues/4
- In the first usecase, booting my gnumach version with an only cpu, the booting stops just after start.I tried to comment the *acpi_setup() *call, which starts the cpu enumeration, but It isn't the cause. Debugging the code with GDB, I also discard problems with *start_other_cpus() *call, or in the *lapic *memory reserve in *extra_setup()*. I attach a screenshot with the crash in this usecase. - In the second usecase, the system seems to crash after enable the 3rd processor. Debugging the code, I found this situation: - The 2nd cpu fails meanwhile try to enable PGE bit in CR4, during paging configuration. - The 1st cpu fails together the second, but I didn't find the point - The 3rd cpu continues its configuration, but fails after call to *slave_main()* I attach another screenshot with the crash in this usecase The source code is here: https://github.com/AlmuHS/GNUMach_SMP My latest work is in *wip *branch: https://github.com/AlmuHS/GNUMach_SMP/tree/wip Can you help me to investigate these issues? Thanks
