1702 6772 d 11 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1138 6850 d 8 h jermar /kernel/trunk/ CPU stacks must have two frames on ia64.
Make sure both thread stack frames are mapped in before_thread_runs_arch().
Take STACK_FRAMES into account during kernel memory layout initialization in main_bsp().
 
1137 6850 d 12 h vana /kernel/trunk/arch/ia64/include/ context_set patch in kernel for changed allocation of ia64 RSE and stack  
1053 6861 d 8 h vana /kernel/trunk/ Itanium FPU Lazy context switching... but not so much tested  
993 6863 d 5 h jermar /kernel/trunk/arch/ia64/ Fix bug in switch to userspace on ia64: ensure start in bank 1.
Fix bug in tlb_invalidate_all() that cause interrupts to be unconditionally enabled.
Optimize context switching by discarding packed attribute of context structures.
 
919 6868 d 12 h jermar /kernel/trunk/ ia64 work.
Changes to make userspace work (kernel part).
Use ski.conf from contrib directory to run Ski.

There is actually no appropriate syscall handler yet.
 
564 6960 d 2 h jermar /kernel/trunk/ Send in some improvements.  
534 6963 d 5 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.  
532 6963 d 6 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.  
501 6975 d 10 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel.  
445 6990 d 10 h jermar /SPARTAN/trunk/arch/ia64/ ia64 work.
Fix SP_DELTA alignment.
Cosmetics.
 
443 6990 d 11 h jermar /SPARTAN/trunk/arch/ia64/ ia64 work.
Do not break memory stack alignment in heavyweight interrupt handler.
Reserve scratch area for nested procedure calls on memory stack.
 
415 7009 d 12 h jermar /SPARTAN/trunk/arch/ia64/include/ Make context_set() reset ar.pfs.pfm (especially ar.pfs.pfm.sol) so that register stack does not underflow.  
414 7010 d 15 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 7011 d 2 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.
 
403 7018 d 5 h jermar /SPARTAN/trunk/arch/ Small improvement in pte_t type definition.  
402 7018 d 14 h jermar /SPARTAN/trunk/ Add ALIGN() macro.

Fix usage of early_mapping() in main.c.
The previous version would not map part of the heap.
Please, review.
 
354 7040 d 10 h jermar /SPARTAN/trunk/ Physical memory management work.
Define structures for frame zones and frames.

Add some comments.
 
322 7050 d 2 h jermar /SPARTAN/trunk/arch/ia64/ Reduce IA-64 context_t according to IA-64 ABI.

Make IA-64 port compile again.
 
180 7060 d 5 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.
 
173 7064 d 4 h jermar /SPARTAN/trunk/ Preparations for weaker preemption model.
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.
 
97 7156 d 13 h jermar /SPARTAN/trunk/ Add context_set() macro to support extended behaviour for architectures with more than one stack (e.g. IA-64).
Now there is one generic context_set() defined in include/context.h and one IA-64 specific defined in arch/ia64/include/context.h.
 
94 7161 d 3 h jermar /SPARTAN/trunk/ IA-64 work.
Add application registers ar.lc, ar.ec, ar.ccv, ar.csd, ar.ssd to context_t.
Add store/load operations for ar.lc, ar.ec, ar.ccv, ar.csd, ar.ssd to context_save()/restore().
Add application registers ar.rcs, ar.bsp and ar.rnat to context_t.
Proper store/load operations for ar.rcs, ar.bsp and ar.rnat is in the works.

FPU cleanup.
Remove call set_TS_flag() from cpu_identify().
Remove unneeded includes from FPU test #1.
 
83 7163 d 9 h jermar /SPARTAN/trunk/arch/ia64/ IA-64 work.
Add ar.pfs and ar.unat (caller and callee) application registers to context_t.
Change st8/ld8 instructions on general registers to st8.spill and ld8.fill instructions.
 
82 7164 d 2 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 7164 d 4 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().
 
59 7171 d 1 h jermar /SPARTAN/trunk/ Move architecture independent memcopy() and memsetb() out of MIPS subtree and place them in src/lib/ as _memcopy() and _memsetb().
Add MIPS native memsetb().
Add IA-64 native memcpy().

More complete and *almost* functional versions of IA-64 context_save() and context_restore().
 
56 7173 d 2 h vana /SPARTAN/trunk/ Added fpu_context.h arch dep files and removed struct fpu_context from context.h files  
51 7173 d 5 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.
 
45 7173 d 15 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.
 
35 7180 d 14 h jermar /SPARTAN/trunk/ Early support for IA-64 architecture.
