373 6879 d 13 h jermar /SPARTAN/trunk/ Physical memory management work.
Add "__attribute__ ((packed))" to frame_t so that it takes up less space.
Note that this is essential as there is lot of these structures.
Remove busy list from zone_t as it is redundant.
 
368 6881 d 20 h jermar /SPARTAN/trunk/ Physical memory management work.
New frame allocator.
Some architectures need to have bigger heap.
 
367 6882 d 11 h jermar /SPARTAN/trunk/ Physical memory management work.
Implement zone_*() and some frame_*() functions.
 
366 6882 d 12 h jermar /SPARTAN/trunk/include/ Add zone pointer to frame_t.

361 6883 d 14 h bondari /SPARTAN/trunk/ Memory routines per-arch declations for future implementation  
360 6883 d 20 h jermar /SPARTAN/trunk/ Compilation fixes.
memcpy() must be declared in memstr.h
 
358 6884 d 12 h bondari /SPARTAN/trunk/ built-in memcpy is not used anymore on IA-32.

355 6884 d 19 h jermar /SPARTAN/trunk/include/mm/ Add 'base' attribute to frame_zone_t structure.  
354 6884 d 19 h jermar /SPARTAN/trunk/ Physical memory management work.
Define structures for frame zones and frames.

Add some comments.
 
338 6891 d 19 h jermar /SPARTAN/trunk/ Avoid code duplication by creating generic byteorder.h.
Some naming changes in swap functions.
 
331 6891 d 22 h bondari /SPARTAN/trunk/ Generic quicksort and bubble sort implementation.
ACPI MADT parser now uses qsort() for index sorting
 
309 6897 d 0 h palkovsky /SPARTAN/trunk/ Added architecture independent hooks for fpu lazy context switching.
It is enabled by defining FPU_LAZY
 
292 6898 d 11 h jermar /SPARTAN/trunk/ Add byteorder.h to support conversions between different endianesses.
Add native_le2host().

Use native_le2host() in get_symtab_entry().
 
270 6899 d 17 h palkovsky /SPARTAN/trunk/ Symbols now include filename  
268 6899 d 17 h palkovsky /SPARTAN/trunk/ Added symbol table lookup in exceptions.
This breaks ia64 & ppc architecture compiles.
 
265 6899 d 21 h palkovsky /SPARTAN/trunk/ Added basic FPU context (not working).
Added CPU utilities from ia32
 
264 6899 d 21 h cejka /SPARTAN/trunk/ E option in printf added.  
251 6900 d 10 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.
 
228 6901 d 19 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 6901 d 19 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.
 
223 6902 d 1 h jermar /SPARTAN/trunk/ Preemption work.
Instrument spinlock functions with preemption_disable() and preemption_enable() calls.
 
221 6902 d 1 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.
 
210 6902 d 12 h decky /SPARTAN/trunk/ many PPC stuff, platform dependent arch.h header files  
207 6902 d 22 h decky /SPARTAN/trunk/ separated stack mapping  
205 6903 d 0 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().
 
200 6903 d 12 h palkovsky /SPARTAN/trunk/ Added putchar to AMD  
198 6903 d 12 h jermar /SPARTAN/trunk/ Switch order of 'src' and 'dst' arguments in some left-over uses of memcopy.

Cleanup.
 
195 6903 d 14 h vana /SPARTAN/trunk/ 1) memcopy and _memcopy functions rewriten to ANSI C norm.

Make all kernel stacks (i.e. startup, scheduler and thread) be STACK_SIZE bytes long.
Reincarnate "the" structure. This time, it is planned to be located at the base of each and every kernel stack.
On IA-32 and MIPS, implement get_stack_base() functions. On the rest of supported platforms, define it to be dummy.
