75 6959 d 1 h vana /SPARTAN/trunk/ Move fpu_owner pointer from cpu_arch_t to cpu_t.  
73 6959 d 21 h vana /SPARTAN/trunk/ Finished FPU lazy context switching - first version. I have not tested it and there are many things which must be changed when
it runs first time OK.		  
68 6959 d 23 h decky /SPARTAN/trunk/ NDEBUG debug symbol, ASSERT debug macro, fancier panic() in debug mode
indentation fixes, ASSERTs		  
57 6962 d 20 h vana /SPARTAN/trunk/ Begin support for FPU context switching on platforms which can't do it in lazy way.  
52 6962 d 21 h vana /SPARTAN/trunk/ Move fpu_context switching functions from context.s to fpu_context.c on all platforms.
Add fpu_context.h.

Make before_thread_runs() arch-independent and create arch dependent version before_thread_runs_arch().		  
35 6970 d 8 h jermar /SPARTAN/trunk/ Early support for IA-64 architecture.  
22 6984 d 1 h jermar /SPARTAN/trunk/ Added before_thread_runs() to cope with TSS of user space tasks.  
16 6991 d 3 h jermar /SPARTAN/trunk/ Switch from mm-based 'the' mechanism to macro-based 'cpu_private_data[CPU_ID_ARCH]' mechanism.
Added l_apic_id() and some other minor APIC changes.
Move gdtr to K_DATA_START section.
Move K_DATA_START section immediately behind K_TEXT_START section so that real-mode addresses work even with growing size of kernel code.		  
15 6992 d 1 h jermar /SPARTAN/trunk/ Introduce macros CPU, THREAD, TASK and use them to replace the->cpu, the->thread, the->task.
Later on, this will make it possible to reference *current* cpu, thread and/or task without the aid from virtual memory.		  
11 7034 d 20 h jermar /SPARTAN/trunk/ Clean up (ia32 vs. i386).
Header files reorganization.		  
10 7035 d 8 h jermar /SPARTAN/trunk/ Be more careful when sending IPI on UP configured as SMP.  
8 7037 d 7 h jermar /SPARTAN/trunk/src/proc/ Use ipi_broadcast() instead of l_apic_broadcast_custom_ipi().  
7 7037 d 8 h jermar /SPARTAN/trunk/ New IPI for waking up idle CPU's halted in scheduler.
Added architecture-independent ipi_broadcast().		  
1 7042 d 2 h jermar /SPARTAN/ Initial import
