1780 6749 d 15 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1702 6770 d 17 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
534 6961 d 12 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.  
532 6961 d 12 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.  
501 6973 d 17 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel.  
414 7008 d 22 h jermar /SPARTAN/trunk/ Create generic context_save() and context_restore().
These two functions are defined inline and only call context_save_arch() and context_restore_arch(), respectively.
The main purpose of this is to enable centralized commenting of these important and tricky functions.		  
413 7009 d 8 h jermar /SPARTAN/trunk/ Rename cpu_priority_{high|low|restore|read} functions to interrupts_{disable|enable|restore|read}.
Rename pri_t to ipl_t (Interrupt Priority Level).
Rename thread_t::pri to thread_t::priority.		  
354 7038 d 17 h jermar /SPARTAN/trunk/ Physical memory management work.
Define structures for frame zones and frames.

Add some comments.		  
312 7050 d 10 h jermar /SPARTAN/trunk/arch/ia32/ According to IA-32 ABI, %edx and %ecx don't have to be saved accross function calls.
Remove these registers from context_t and adjust context_save() and context_restore() to make use of this fact.		  
180 7058 d 11 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.		  
82 7162 d 9 h jermar /SPARTAN/trunk/arch/ IA-64 work.
Add the rest of branch registers to context_t.
Add predicate registers to context_t.
Modify context_save()/context_restore() to save/restore branch registers and predicate registers.
Change SP_DELTA to 0 since both context_save() and context_restore() are leaf procedures and as such don't use the scratch area.
Change pri_t to be __u64 instead of __u32.		  
81 7162 d 11 h jermar /SPARTAN/trunk/ Add SP_DELTA macro for each architecture.
On IA-32, this macro represents two doublewords that must be on the stack when switching to a new stack.
On MIPS, there is no need to fix sp when switching to a new stack.
On IA-64, this macro is used to allocate the 16-byte scratch area.

IA-64 work.
Changes in start.S. More changes to come.
Define memcopy().

Janitorial fixes.
Add missing #include <panic.h> to rwlock4/test.c.
Remove wrong use of inline keyword from both declaration and definition of l_apic_id().		  
56 7171 d 9 h vana /SPARTAN/trunk/ Added fpu_context.h arch dep files and removed struct fpu_context from context.h files  
51 7171 d 12 h jermar /SPARTAN/trunk/ Small changes, fix last few wrong indentations.
TODO cleanup.

IA-64 bits.
Call main_bsp from kernel_image_start().
Prepare for IA-64 context_save and context_restore.		  
46 7171 d 18 h vana /SPARTAN/trunk/ Remove fpu_context pointer from context_t.
Add fpu_context statically to thread_t.
Two functions for saving and restoring FPU context on lazy switch.		  
45 7171 d 22 h vana /SPARTAN/trunk/ Added fpu_context_t type.
IA-32's version of this type contains array of 512 bytes to be used by FXSAVE ... instructions.		  
11 7243 d 8 h jermar /SPARTAN/trunk/ Clean up (ia32 vs. i386).
Header files reorganization.		  
1 7250 d 14 h jermar /SPARTAN/ Initial import
