128 6885 d 18 h jermar /SPARTAN/trunk/arch/ia32/ Create IA-32 interface for bringing SMP up.

127 6885 d 19 h jermar /SPARTAN/trunk/arch/ Copyright owner of arch/mips/src/mm/asid.c is Martin Decky.

123 6888 d 11 h decky /SPARTAN/trunk/arch/mips/ handle more MIPS exceptions  
122 6889 d 8 h jermar /SPARTAN/trunk/include/mm/ Remove one extra line left over from debugging process.  
121 6889 d 9 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 6903 d 7 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 6904 d 10 h jermar /SPARTAN/trunk/ Start with generic 4-level page table interface.

Usual cleanup.		  
118 6917 d 12 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 6919 d 15 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 6923 d 14 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 6924 d 7 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 6924 d 17 h jermar /SPARTAN/trunk/src/proc/ Fix wrong locking order in scheduler.  
113 6927 d 6 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 6927 d 10 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 6927 d 11 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 6928 d 15 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 6930 d 11 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.		  
108 6930 d 16 h decky /SPARTAN/trunk/ doxygen-style comments
NDEBUG in Makefile.config		  
107 6930 d 16 h decky /SPARTAN/trunk/src/ doxygen-style comments
cleanups		  
106 6930 d 17 h jermar /SPARTAN/trunk/ IA-32 fixes.
Use kernel addresses instead of physical addresses in map_page_to_frame().
Physical addresses are supposed to only be exported to mm hardware.
Because of this fix, userspace is functional again.

Remap EGA videoram to (0x80000000 + videoram) and change the ega driver to work with the new address.

Minor cosmetics through out the code.
Changes in linker scripts.		  
105 6931 d 7 h jermar /SPARTAN/trunk/ Big changes in IA-32 address space map.
Now the kernel is mapped above 0x80000000. Finally!
Userspace address space starts at 0x00000000.
Changes in many places.
This improvement temporarily breaks SMP and most likely also other stuff.
Supported size of memory is now only 4M as it is the biggest size that can be mapped at once on IA-32.

Changes in linker script.
Changes required because of the above.
Do not patch hardcoded_* variables but assign to them instead.

Cosmetic changes here and there.		  
104 6933 d 10 h bondari /SPARTAN/trunk/doc/ Add Sergey Bondari to the authors - workstation is ready :)
