689 6714 d 0 h bondari /kernel/trunk/ Frame alloc test #1  
687 6714 d 0 h jermar /kernel/trunk/ Memory management work.
Pass address space identifier to functions in page_operations to support single global page hash table.
 
674 6718 d 5 h cejka /kernel/trunk/ Support for printing float numbers in kernel removed.  
627 6738 d 0 h jermar /kernel/trunk/ Fix ia64 and sparc64 to compile with new atomic_t.
Fix rwlock test #5 and semaphore test #1 to compile with new atomic_t.

sparc64 work.
TBA must be set before a function call when MMU is switched off.
 
625 6738 d 0 h palkovsky /kernel/trunk/ We are now almost -Wall clean.
- redefined atomic_t
- deleted many, many unused variables
- some minor code cleanups found using compiler warning.
 
623 6738 d 6 h jermar /kernel/trunk/ Add SPINLOCK_DECLARE and SPINLOCK_INITIALIZE macros.
SPINLOCK_DECLARE is to be used instead of direct spinlock_t declarations
in dynamically allocated structures on which spinlock_initialize() is called after
their creation.
SPINLOCK_INITIALIZE is to be used instead of direct spinlock_t declarations
of global spinlocks. It declares and initializes the spinlock.
Moreover, both macros are empty on UP so that -Wall warnings about unused structures
get supressed.
 
609 6740 d 23 h palkovsky /kernel/trunk/ added support for breakpoints to mips32  
548 6746 d 21 h jermar /kernel/trunk/ Cleanup and fixes.  
534 6748 d 21 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.  
532 6748 d 21 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.  
501 6761 d 1 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel.  
492 6761 d 18 h jermar /SPARTAN/trunk/ Rename map_page_to_frame() to page_mapping_insert() and find_mapping() to page_mapping_find().
New names should make it more apparent that these two belong together.
 
483 6768 d 21 h jermar /SPARTAN/trunk/ For now, each architecture must use its own -O switch (-O2 doesn't work for ia64, -O3 doesn't work for mips32).

New mips32 atomic_add() function.

Cleanup.
 
475 6773 d 3 h jermar /SPARTAN/trunk/ Define atomic_t type.  
413 6796 d 17 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.
 
401 6806 d 7 h jermar /SPARTAN/trunk/test/mm/mapping1/ Finalize mm mapping test #1 once again.  
400 6806 d 7 h jermar /SPARTAN/trunk/ Finalize mapping1 test.
Record omitted excMod bug in msim.
 
399 6806 d 17 h jermar /SPARTAN/trunk/ mips32 memory management work.
TLB exceptions seem to be working on at least simics.
msim handles TLB Refill and TLB Invalid exceptions well,
but seems to skip writes to the mapped addressies in mm
mapping test #1 (the data is not written and exception
is not triggered).
 
397 6807 d 7 h jermar /SPARTAN/trunk/ Small changes to mips32 mm.
Small changes in mm mapping test #1.
 
396 6808 d 4 h jermar /SPARTAN/trunk/ Add mm/mapping1 test.
(Will not make it past TLB Invalid exception on mips32.)
Fixes in asid.c.
Make TLB register types union with __u32 value.
Implement tlb_invalidate() for mips32.
(TLB invalidation and shootdown path will have to be revised.)
 
329 6833 d 23 h palkovsky /SPARTAN/trunk/ Basic changes to boot it on SGI Indy.  
326 6834 d 16 h palkovsky /SPARTAN/trunk/ Cleanup of makefiles to have common options in one main makefile.

Add simple build process for different simulators for MIPS.
Added FPU context & lazy FPU context switching to MIPS.
Cleanup of MIPS linker script.
Moved MIPS kernel above 1MB. Not tested on real machine yet, but it might help.

There is something broken with gcc inlined memcpy (either simulator or gcc), it is disabled on BigEndian mips now.
 
296 6839 d 5 h palkovsky /SPARTAN/trunk/ More logical fpu_context_engaged setting.
The sse1 test now correctly tests for thread migration settings.
 
295 6839 d 6 h palkovsky /SPARTAN/trunk/ Test that really tests SSE context switching.  
283 6840 d 7 h palkovsky /SPARTAN/trunk/ IA32 printf-double support migrated to amd64  
266 6841 d 2 h cejka /SPARTAN/trunk/ Support for NaN and infinity in printf.  
264 6841 d 4 h cejka /SPARTAN/trunk/ E option in printf added.  
263 6841 d 4 h palkovsky /SPARTAN/trunk/test/synch/rwlock2/ Bad prototype  
228 6843 d 1 h cejka /SPARTAN/trunk/ Created fmath as basic tool for IEEE 754 floating point numbers.
Added option $F for printf for printing "double" type.
 
225 6843 d 5 h jermar /SPARTAN/trunk/test/synch/rwlock4/ Revert the change in rwlock #4 test that added cpu_priority_high() and cpu_priority_restore() to random().
It is no longer necessary because spinlock disables preemption at least.
 
205 6844 d 7 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().
 
195 6844 d 21 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
 
187 6845 d 3 h cejka /SPARTAN/trunk/ Licence to print1/test.c added.
New function for printing memory map at ia32.
 
183 6845 d 7 h cejka /SPARTAN/trunk/ Small improvements in print1 test and its source code format.  
182 6845 d 7 h cejka /SPARTAN/trunk/ Test for printf added.  
171 6851 d 4 h jermar /SPARTAN/trunk/ Make rwlock test #3 compile again.

Make rwlock test #4 preemption-safe.

Prepare for preemption controlling functions.
 
125 6890 d 19 h jermar /SPARTAN/trunk/ Huge indentation fix.  
119 6906 d 20 h jermar /SPARTAN/trunk/ Start with generic 4-level page table interface.

Usual cleanup.
 
111 6929 d 20 h palkovsky /SPARTAN/trunk/ Code cleanup in scheduler.c thread.c - removed unnecessary spinlock.
atomic_inc, atomic_dec moved to arch/atomic.h instead of arch/smp/atomic.h,
advisable to use even in non-smp mode.
Fixed atomic_inc, atomic_dec in mips architecture.
 
94 6946 d 19 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.
