192	6824 d 20 h	jermar	/SPARTAN/trunk/	Dump implementation of THREAD, TASK and CPU. Implement preemption-safe versions of THREAD, TASK and CPU using THE. Get rid of CPU_ID_ARCH on all architectures. Get rid of write_dr0() and read_dr0() on IA-32. Get rid of cpu_private_data and cpu_private_data_t.
177	6826 d 2 h	jermar	/SPARTAN/trunk/	Add some comments to IA-32 src/boot/boot.S and src/smp.S. Make the boot stack start on page boundary. This is required by get_stack_base(). Define 'THE' macro. Implement preemption_disable() and preemption_enable(). Add memory barrier macros. IA-32 macros need support for older processors. Non IA-32 macros are dummy. Reduction of many #include paths.
173	6829 d 17 h	jermar	/SPARTAN/trunk/	Preparations for weaker preemption model. Make all kernel stacks (i.e. startup, scheduler and thread) be STACK_SIZE bytes long. Reincarnate "the" structure. This time, it is planned to be located at the base of each and every kernel stack. On IA-32 and MIPS, implement get_stack_base() functions. On the rest of supported platforms, define it to be dummy.
171	6831 d 2 h	jermar	/SPARTAN/trunk/	Make rwlock test #3 compile again. Make rwlock test #4 preemption-safe. Prepare for preemption controlling functions.
75	6934 d 20 h	vana	/SPARTAN/trunk/	Move fpu_owner pointer from cpu_arch_t to cpu_t.
31	6950 d 22 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	6952 d 1 h	jermar	/SPARTAN/trunk/	Small improvements.
20	6964 d 0 h	jermar	/SPARTAN/trunk/	Smarter definition of CPU macro.
16	6966 d 21 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.
1	7017 d 20 h	jermar	/SPARTAN/	Initial import
