355 6829 d 14 h jermar /SPARTAN/trunk/include/mm/ Add 'base' attribute to frame_zone_t structure.  
354 6829 d 14 h jermar /SPARTAN/trunk/ Physical memory management work.
Define structures for frame zones and frames.

Add some comments.		  
265 6844 d 16 h palkovsky /SPARTAN/trunk/ Added basic FPU context (not working).
Added CPU utilities from ia32		  
167 6859 d 16 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.		  
125 6894 d 7 h jermar /SPARTAN/trunk/ Huge indentation fix.  
122 6895 d 7 h jermar /SPARTAN/trunk/include/mm/ Remove one extra line left over from debugging process.  
121 6895 d 7 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 6909 d 6 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 6910 d 8 h jermar /SPARTAN/trunk/ Start with generic 4-level page table interface.

Usual cleanup.		  
116 6929 d 13 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.		  
109 6936 d 9 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.		  
102 6942 d 9 h jermar /SPARTAN/trunk/ IA-64 work.
Redefine FRAME_SIZE to "(16*1024)" instead of "2*4096". Note that the latter definition was wrong because of the lack of "()".
Take panic_printf(), cpu_halt() and memsetb() out of fake.s and implement them properly in asm.S.
Move ski_init_console() from arch_post_mm_init() to arch_pre_mm_init().
In start.S, write r0 to ar.bspstore.

Janitorial fixes.
Add count_t type.
Replace several occurrences of int and __u32 by count_t or size_t.
Shorten several panic strings.		  
72 6959 d 9 h decky /SPARTAN/trunk/ size_t usage
const qualifier
code cleanup		  
6 7037 d 21 h jermar /SPARTAN/trunk/ shootdown vs. shutdown  
5 7038 d 7 h jermar /SPARTAN/trunk/ TLB shootdown.  
1 7041 d 12 h jermar /SPARTAN/ Initial import
