156	6872 d 2 h	decky	/SPARTAN/trunk/	PPC work in progress
153	6875 d 14 h	jermar	/SPARTAN/trunk/	Add memory barriers into spinlock_*(). Implement CS_{ENTER\|LEAVE}_BARRIER() for IA-32 (no-op). Provide incomplete CS_{ENTER\|LEAVE}_BARRIER() macros for IA-64 and MIPS as well. Small changes here and there.
149	6887 d 17 h	jermar	/SPARTAN/trunk/	Fix IA-32's get_memory_size() to return size of memory in bytes instead of in kilobytes. Some cosmetics in memory map detection. The IA-32 kernel is functional again.
146	6892 d 23 h	cejka	/SPARTAN/trunk/	Memory size detection for ia32 completed.
136	6893 d 23 h	vana	/SPARTAN/trunk/	Error word support debuging and testing passed with #NM & #GP exceptions.
135	6894 d 0 h	jermar	/SPARTAN/trunk/	Fix setters of page table attributes for both IA-32 and MIPS.
125	6898 d 15 h	jermar	/SPARTAN/trunk/	Huge indentation fix.
121	6899 d 15 h	jermar	/SPARTAN/trunk/	Begin MIPS implementation of 4-level page table interface. Add email address to each item in doc/AUTHORS. Correct type names in comments in mm/vm.c. Introduce ptl0 pointer in vm_t.
120	6913 d 14 h	jermar	/SPARTAN/trunk/	Generic 4-level page tables interface & implementation (review & test). Implement more architecture dependant macros on IA-32. Provide fake implementation on IA-64 and MIPS. Convert map_page_to_frame() to use the new interface. Move adjusted map_page_to_frame() from IA-32's arch/mm/page.c to the generic mm/page.c.
119	6914 d 17 h	jermar	/SPARTAN/trunk/	Start with generic 4-level page table interface. Usual cleanup.
118	6927 d 19 h	jermar	/SPARTAN/trunk/	Replace confusing comment in scheduler.c. Add warning/explanatory comment to arch.h saying that CPU, THREAD and TASK macros are preemption-unsafe.
117	6929 d 21 h	jermar	/SPARTAN/trunk/	Do panic() on page_fault(). Good for long testing in SMP mode as silent "extinctions" of a CPU are no longer supported. Tiny changes here and there.
116	6933 d 21 h	jermar	/SPARTAN/trunk/	Add map_structure() to automate mapping of memory structures that can span multiple pages and/or cross page boundaries. Change ACPI map_sdt() to use map_structure(). Small changes in MPS code. The extra frame allocation for accessing frame 0 is unnecessary as it is possible to access frame 0 from kernel address space. Zero TSS descriptor in the newly prepared GDT.
115	6934 d 14 h	jermar	/SPARTAN/trunk/	Implement several assembler functions in gcc's __asm__ notation instead of in .s or .S file. Gain both better speed and size.
114	6935 d 0 h	jermar	/SPARTAN/trunk/src/proc/	Fix wrong locking order in scheduler.
113	6937 d 13 h	jermar	/SPARTAN/trunk/	SMP recovery patch #2 (SMP is no longer broken !!!). Fix missing KA2PA() operation in ap.S which was causing page faults during AP early initialization. Fix bug in map_page_to_frame(): 'root' was interpretted as kernel address while read_dba() returns physical address. Make references to page directory and page tables use kernel addresses instead of physical addresses. Massive frame allocation code cleanup. Basically revert to what we had had before implementation of userspace. Usual cosmetics.
112	6937 d 17 h	jermar	/SPARTAN/trunk/	Define two placeholder functions for atomic_inc and atomic_dec on IA-64. Add Ondrej Palkovsky to doc/AUTHORS. Tweaks in IA-32 low level code to bring SMP back to life. (SMP still broken)
111	6937 d 17 h	palkovsky	/SPARTAN/trunk/	Code cleanup in scheduler.c thread.c - removed unnecessary spinlock. atomic_inc, atomic_dec moved to arch/atomic.h instead of arch/smp/atomic.h, advisable to use even in non-smp mode. Fixed atomic_inc, atomic_dec in mips architecture.
110	6938 d 22 h	jermar	/SPARTAN/trunk/	SMP recovery patch #1. (SMP still broken) Move ap_boot() to K_TEXT_START_2 section. Change ap_boot() to cope with mapping of kernel address space. Change some addresses in mps.c from kernel to physical. MIPS. Move msim dprinter device to 0xB0000000. This address is from kseg1 (unmapped, uncached) segment.
109	6940 d 18 h	jermar	/SPARTAN/trunk/	Discard 'copy' parameter of map_page_to_frame(). Introduce 'root' parameter of map_page_to_frame(). If 'root' is zero, page directory address is read from CPU. Otherwise 'root' is used as page directory address. Add missing word to new doxygen-style comments in scheduler.c.
