206	6891 d 22 h	palkovsky	/SPARTAN/trunk/	Better types for ia32 drivers, so that they can be reused in amd64. Build script cleanup amd64. New code / not working yet / in amd64.
205	6891 d 23 h	jermar	/SPARTAN/trunk/	Get rid of memcopy(). All we now have is memcpy() and _memcpy(). memcpy() is defined to be builtin. Where not applicable, architectures must implement memcpy() code or call slowish _memcopy().
202	6892 d 11 h	palkovsky	/SPARTAN/trunk/src/lib/	Fixed bad types in memsetw.
200	6892 d 11 h	palkovsky	/SPARTAN/trunk/	Added putchar to AMD
198	6892 d 11 h	jermar	/SPARTAN/trunk/	Switch order of 'src' and 'dst' arguments in some left-over uses of memcopy. Cleanup.
197	6892 d 13 h	palkovsky	/SPARTAN/trunk/	Context-save/restore in AMD64
195	6892 d 13 h	vana	/SPARTAN/trunk/	1) memcopy and _memcopy functions rewriten to ANSI C norm. 2) Repaired ia32,ia64 and mips version of SPARTAN to work with this memcopy functions 3) Warning for non declared funcions added and repaired ia32,ia64 and mips versions to pass build process with this warning and Werror option
192	6892 d 15 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.
184	6892 d 23 h	jermar	/SPARTAN/trunk/	Add lib/the.c. Add and deploy the_initialize() and the_copy(). Make IA-32's before_thread_runs() use SP_DELTA macro.
183	6892 d 23 h	cejka	/SPARTAN/trunk/	Small improvements in print1 test and its source code format.
182	6893 d 0 h	cejka	/SPARTAN/trunk/	Test for printf added.
181	6893 d 0 h	cejka	/SPARTAN/trunk/	Bugs in printf and va_arg functions repaired.
180	6893 d 12 h	jermar	/SPARTAN/trunk/	Globalize 'size' and 'delta' and rename them to 'kernel_size' and 'heap_delta'. Fix heap initialization to take 'heap_delta' into account. Implement IA-64 get_stack_base(). Adjust SP_DELTA's to consider one extra word on stack. (So that the stack pointer is within appropriate limits even on IA-64). More #include cleanup.
179	6893 d 15 h	decky	/SPARTAN/trunk/	frmaebuffer font
177	6893 d 21 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.
174	6897 d 12 h	jermar	/SPARTAN/trunk/	Small changes. Coding style fix in main.c. Make 'cli' be the first instruction in boot.S again.
171	6898 d 21 h	jermar	/SPARTAN/trunk/	Make rwlock test #3 compile again. Make rwlock test #4 preemption-safe. Prepare for preemption controlling functions.
170	6901 d 10 h	jermar	/SPARTAN/trunk/	Add comment to scheduler.c explaining the reason behind saving CPU priority of preempted thread. Remove two unnecessary cpu_priority_high() calls.
168	6902 d 11 h	jermar	/SPARTAN/trunk/	Add type cast to __address in vm_create(). This seems to fix the problem with userspace. Looks like KA2PA() returned wrong address when applied on pte_t *. Uncomment panic() in gp_fault(). Get rid of cli and sti in userspace code.
167	6903 d 20 h	jermar	/SPARTAN/trunk/	Switch over to per vm_t page tables. (breaks ia32 userspace) Define dummy memcopy() for amd64 and ppc to satisfy compiler. Get rid of problematic #include <arch/mm/page.h> in mm/page.h. Indentation fixes and small changes here and there.
164	6905 d 14 h	palkovsky	/SPARTAN/trunk/	Basics for amd64 architecture. It does compile, but it does not work yet.
160	6911 d 10 h	jermar	/SPARTAN/trunk/	PPC work. Define dummy implementations of many functions in fake.s. Define kernel_image_start in start.S.
158	6911 d 18 h	decky	/SPARTAN/trunk/src/mm/	remove forgotten comment
157	6911 d 18 h	decky	/SPARTAN/trunk/	remove cyclic including, change linker script path
156	6911 d 21 h	decky	/SPARTAN/trunk/	PPC work in progress
153	6915 d 10 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	6927 d 13 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	6932 d 19 h	cejka	/SPARTAN/trunk/	Memory size detection for ia32 completed.
136	6933 d 18 h	vana	/SPARTAN/trunk/	Error word support debuging and testing passed with #NM & #GP exceptions.
135	6933 d 19 h	jermar	/SPARTAN/trunk/	Fix setters of page table attributes for both IA-32 and MIPS.
125	6938 d 11 h	jermar	/SPARTAN/trunk/	Huge indentation fix.
121	6939 d 11 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	6953 d 10 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	6954 d 12 h	jermar	/SPARTAN/trunk/	Start with generic 4-level page table interface. Usual cleanup.
118	6967 d 14 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	6969 d 17 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	6973 d 17 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	6974 d 9 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	6974 d 19 h	jermar	/SPARTAN/trunk/src/proc/	Fix wrong locking order in scheduler.
113	6977 d 8 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.
