| H A D | trgt_amd64.c | diff 246893 Sun Feb 17 00:31:28 MST 2013 marcel In kthr.c, obtain the address of the PCB for threads that were running on a core, when the core was stopped, by calling kgdb_trgt_core_pcb(). This has 2 advantages: 1. We don't need to include a machine-specific header anymore and as such kthr.c is truly machine independent. This allows the code to be used in a cross-debugger. 2. We don't need to lookup stoppcbs in generic code when it's an inherently target-spicific symbol. It does not exist for ia64. Implement kgdb_trgt_core_pcb() for all architectures, except ia64, by calling a common function called kgdb_trgt_stop_pcb(). This function differs from kgdb_trgt_core_pcb() in that it gets the size of the PCB structure as an argument and as such remains machine independent. On ia64 the PCB for stopped cores is in the PCPU structure itself. This for better scaling. The implementation of kgdb_trgt_core_pcb() for ia64 uses the cpuid_to_pcpu[] array to to obtain the address of the PCB structure. |
