61 6994 d 2 h decky /SPARTAN/trunk/src/debug/ doxygen-style comments  
59 6994 d 19 h jermar /SPARTAN/trunk/ Move architecture independent memcopy() and memsetb() out of MIPS subtree and place them in src/lib/ as _memcopy() and _memsetb().
Add MIPS native memsetb().
Add IA-64 native memcpy().

More complete and *almost* functional versions of IA-64 context_save() and context_restore().		  
57 6996 d 19 h vana /SPARTAN/trunk/ Begin support for FPU context switching on platforms which can't do it in lazy way.  
52 6996 d 20 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().		  
47 6997 d 5 h jermar /SPARTAN/trunk/src/main/ Remove redundant comments.  
46 6997 d 5 h vana /SPARTAN/trunk/ Remove fpu_context pointer from context_t.
Add fpu_context statically to thread_t.
Two functions for saving and restoring FPU context on lazy switch.		  
44 6997 d 9 h vana /SPARTAN/trunk/src/ JV's first commit :-)  
43 6997 d 21 h jermar /SPARTAN/trunk/src/ Add comfortable build and cleanup scripts for ia32, ia64 and mips architectures.  
42 6997 d 21 h jermar /SPARTAN/trunk/ Add stdarg.h to support variable argument list functions on architectures with compiler support for __builtin_va_*.
stackarg.h is kept for those architectures which lack that kind of support and for testing purposes.

Make printing functions use the __native type and support the maximum integer width.		  
40 6999 d 6 h jermar /SPARTAN/trunk/ Variable argument list support for architectures passing arguments on stack.  
37 7002 d 8 h jermar /SPARTAN/trunk/ More IA-64 work.
IA-64 putchar() for Ski simulator.
Linker script changes.		  
35 7004 d 8 h jermar /SPARTAN/trunk/ Early support for IA-64 architecture.  
34 7005 d 2 h jermar /SPARTAN/trunk/ More ACPI work.
Initial MADT table parsing.

SMP renaming and reorganization to reflect there are more ways to bring SMP up.		  
32 7007 d 22 h jermar /SPARTAN/trunk/ ACPI detection code.
MP detection code rewrite.
Minor changes.		  
31 7009 d 3 h jermar /SPARTAN/trunk/ Replace the deadlock-prone TLB shootdown algorithm with a deadlock-free implementation.
The implementation is a variant of the CMU TLB consistency algorithm.
Very inefficient implementation of a very inefficient (but correct) algorithm.		  
28 7010 d 6 h jermar /SPARTAN/trunk/ Small improvements.  
27 7010 d 21 h jermar /SPARTAN/trunk/ APIC changes and fixes.
Be more robust during MP configuration.

Do not use APIC ID as CPU_ID_ARCH anymore.
Changing APIC ID's is not a good idea.
Use dr0 register instead.		  
26 7013 d 5 h jermar /SPARTAN/trunk/ Code cleanup after arch_init() splitting.
Restore %ds and %es registers before iret.		  
25 7013 d 8 h jermar /SPARTAN/trunk/src/ Fix waitq_sleep_timeout() to call before_thread_runs() when handling timeout.  
24 7016 d 0 h jermar /SPARTAN/trunk/ Small fixes.  
23 7016 d 3 h jermar /SPARTAN/trunk/ Fix wrong order of *_init() function calls.  
22 7018 d 1 h jermar /SPARTAN/trunk/ Added before_thread_runs() to cope with TSS of user space tasks.  
20 7022 d 5 h jermar /SPARTAN/trunk/ Smarter definition of CPU macro.  
19 7024 d 23 h jermar /SPARTAN/trunk/ Re-enable tests and fix include paths' in them.  
16 7025 d 2 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 7026 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 7068 d 19 h jermar /SPARTAN/trunk/ Clean up (ia32 vs. i386).
Header files reorganization.		  
10 7069 d 7 h jermar /SPARTAN/trunk/ Be more careful when sending IPI on UP configured as SMP.  
8 7071 d 7 h jermar /SPARTAN/trunk/src/proc/ Use ipi_broadcast() instead of l_apic_broadcast_custom_ipi().  
7 7071 d 7 h jermar /SPARTAN/trunk/ New IPI for waking up idle CPU's halted in scheduler.
Added architecture-independent ipi_broadcast().		  
6 7072 d 11 h jermar /SPARTAN/trunk/ shootdown vs. shutdown  
5 7072 d 21 h jermar /SPARTAN/trunk/ TLB shootdown.  
3 7076 d 1 h jermar /SPARTAN/trunk/src/ Minor change.  
2 7076 d 1 h jermar /SPARTAN/trunk/src/ Add ia64 and amd64 to config Makefile.  
1 7076 d 2 h jermar /SPARTAN/ Initial import
