368 6822 d 19 h jermar /SPARTAN/trunk/ Physical memory management work.
New frame allocator.
Some architectures need to have bigger heap.		  
367 6823 d 10 h jermar /SPARTAN/trunk/ Physical memory management work.
Implement zone_*() and some frame_*() functions.		  
257 6840 d 23 h palkovsky /SPARTAN/trunk/ Added basic FPU context (not working).
Added CPU utilities from ia32
Fixed bug in vm.c that wanted PTL to be mapped in bottom memory.		  
251 6841 d 8 h palkovsky /SPARTAN/trunk/ Changes, that were needed to make it work on Bochs.
- We CAN use the NX bit in paging tables, but we have
to initialize the NXE bit in EFER register first.		  
236 6842 d 16 h jermar /SPARTAN/trunk/src/ Add missing header into kinit.c.

Do not use PA2KA() on dst_ptl0.		  
227 6842 d 18 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 6842 d 18 h palkovsky /SPARTAN/trunk/ Fixed typo in 'outb' instruction.
Paging basically working.		  
219 6843 d 7 h palkovsky /SPARTAN/trunk/ Fixed bad type in frame.c.
Amd64 prints banner.		  
205 6843 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().		  
198 6844 d 11 h jermar /SPARTAN/trunk/ Switch order of 'src' and 'dst' arguments in some left-over uses of memcopy.

Cleanup.		  
195 6844 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		  
168 6854 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 6855 d 19 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.		  
158 6863 d 18 h decky /SPARTAN/trunk/src/mm/ remove forgotten comment  
157 6863 d 18 h decky /SPARTAN/trunk/ remove cyclic including, change linker script path  
125 6890 d 11 h jermar /SPARTAN/trunk/ Huge indentation fix.  
121 6891 d 10 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 6905 d 9 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.		  
116 6925 d 16 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 6926 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.
