242	6907 d 2 h	palkovsky	/SPARTAN/trunk/	Fixed stack settings in boot.S in real mode. Added ia32 memmap support. Added cpuid support.
241	6907 d 20 h	palkovsky	/SPARTAN/trunk/	Cleanups so that it compiles on ia-32 & amd-64 cleanly
239	6907 d 21 h	vana	/SPARTAN/trunk/	Missing ";" added
238	6907 d 22 h	vana	/SPARTAN/trunk/	Register dump on IA-64 exceptions
236	6907 d 23 h	jermar	/SPARTAN/trunk/src/	Add missing header into kinit.c. Do not use PA2KA() on dst_ptl0.
235	6907 d 23 h	decky	/SPARTAN/trunk/	load the kernel above 1 MB on IA-32
228	6908 d 0 h	cejka	/SPARTAN/trunk/	Created fmath as basic tool for IEEE 754 floating point numbers. Added option $F for printf for printing "double" type.
227	6908 d 1 h	jermar	/SPARTAN/trunk/	Add couple of assertions CPU != NULL. Change type of nrdy from int to count_t. Rewrite halt() to avoid page fault when CPU == NULL.
226	6908 d 1 h	palkovsky	/SPARTAN/trunk/	Fixed typo in 'outb' instruction. Paging basically working.
223	6908 d 6 h	jermar	/SPARTAN/trunk/	Preemption work. Instrument spinlock functions with preemption_disable() and preemption_enable() calls.
221	6908 d 7 h	jermar	/SPARTAN/trunk/	Preemption work. Define PREEMPTION_DISABLED macro. This macro determines the level of preemptivity (0 = preemption enabled, THE->preemption_disabled = no preemption inside spinlock, 1 = preemption disabled). Reformulate preemption code in clock.c to consider PREEMPTION_DISABLED.
220	6908 d 7 h	vana	/SPARTAN/trunk/	Universal exception handler and all exceptions routine to call it added
219	6908 d 14 h	palkovsky	/SPARTAN/trunk/	Fixed bad type in frame.c. Amd64 prints banner.
216	6908 d 16 h	palkovsky	/SPARTAN/trunk/	hardcoded_symbol fixed into linker script on amd64/ia32/mips architecture
214	6908 d 17 h	vana	/SPARTAN/trunk/src/
213	6908 d 18 h	jermar	/SPARTAN/trunk/	Add some comments.
212	6908 d 18 h	vana	/SPARTAN/trunk/	Basic exception support added for ia64 arch ......
210	6908 d 18 h	decky	/SPARTAN/trunk/	many PPC stuff, platform dependent arch.h header files
208	6909 d 3 h	palkovsky	/SPARTAN/trunk/	arch_pre_init_mm now working.
207	6909 d 4 h	decky	/SPARTAN/trunk/	separated stack mapping
206	6909 d 5 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	6909 d 6 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	6909 d 17 h	palkovsky	/SPARTAN/trunk/src/lib/	Fixed bad types in memsetw.
200	6909 d 17 h	palkovsky	/SPARTAN/trunk/	Added putchar to AMD
198	6909 d 18 h	jermar	/SPARTAN/trunk/	Switch order of 'src' and 'dst' arguments in some left-over uses of memcopy. Cleanup.
197	6909 d 19 h	palkovsky	/SPARTAN/trunk/	Context-save/restore in AMD64
195	6909 d 20 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	6909 d 22 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	6910 d 6 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	6910 d 6 h	cejka	/SPARTAN/trunk/	Small improvements in print1 test and its source code format.
182	6910 d 6 h	cejka	/SPARTAN/trunk/	Test for printf added.
181	6910 d 7 h	cejka	/SPARTAN/trunk/	Bugs in printf and va_arg functions repaired.
180	6910 d 19 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	6910 d 22 h	decky	/SPARTAN/trunk/	frmaebuffer font
177	6911 d 4 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	6914 d 18 h	jermar	/SPARTAN/trunk/	Small changes. Coding style fix in main.c. Make 'cli' be the first instruction in boot.S again.
171	6916 d 3 h	jermar	/SPARTAN/trunk/	Make rwlock test #3 compile again. Make rwlock test #4 preemption-safe. Prepare for preemption controlling functions.
170	6918 d 17 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	6919 d 18 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	6921 d 2 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.
