4605 5609 d 18 h decky /branches/snapshot/ add task snapshoting branch  
3972 5735 d 8 h decky /trunk/kernel/ kernel memory management revisited (phase 1): proper support for zone flags
- the zone_t structures are now statically allocated to be easily available
- the locking scheme was simplified
- new flags for non-available zones were introduced
- FRAME_LOW_4_GiB flag is removed, the functionality will be eventually reimplemented using a generic mechanism
 
3206 5970 d 13 h jermar /trunk/kernel/generic/ Avoid deadlock during the 'zone n' kconsole command. Buddy allocator detail is
no longer printed because the effort to avoid the deadlock was simply not worth
it.
 
3057 6003 d 17 h decky /trunk/kernel/generic/src/mm/ proper printf formatting  
2089 6495 d 18 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes
 
2071 6506 d 11 h jermar /trunk/ (c) versus (C)  
1787 6696 d 13 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1780 6703 d 14 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1757 6717 d 19 h jermar /kernel/trunk/ Cleanup of comments.  
1708 6721 d 20 h jermar /kernel/trunk/ Fix some broken doxygen comments.  
1702 6724 d 17 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1248 6771 d 14 h jermar /kernel/trunk/ Add some @file doxygen comments and improve already existing comments.  
1229 6774 d 19 h jermar /kernel/trunk/ Remove the outdated TODO file.
Improve doxygen comments here and there.
 
1224 6775 d 17 h cejka /kernel/trunk/ Fix pointers output format.
Fix format of slab and zones tables.
 
1196 6782 d 18 h cejka /kernel/trunk/ Printf ported back from uspace to kernel.
Printf calls changed to match new conventions.
 
822 6849 d 9 h palkovsky /kernel/trunk/ Changed malloc to include second parameter and documented
recommended usage.
Added zone merging, made ia32 & amd64 to merge found zones.
 
815 6849 d 18 h jermar /kernel/trunk/ Fix sparc64 and ia64 to work with the changed frame allocator.

Fix ppc32 to at least compile.
 
814 6849 d 19 h palkovsky /kernel/trunk/ Cleanup o frame allocator.
Removed early_malloc & initial heap.
Will break ia64, ppc & sparc.
Added e820 table print.
 
813 6850 d 7 h jermar /kernel/trunk/ Change ia64 kernel image to link and load at 0x100000 where
it (or its heap or stack) won't mess up with the ROM region.

Blacklist ia64 frame 0 from frame allocator so that 0 won't be
returned to malloc and friends. This can be reenabled again
once the kernel is not identity mapped.
 
788 6852 d 13 h jermar /kernel/trunk/ Move list and fifo data types to adt/.  
735 6866 d 15 h bondari /kernel/trunk/ Fixes, comments, tests to frame allocator  
701 6878 d 9 h jermar /kernel/trunk/generic/src/mm/ Fix zone_print_one() and zone_print_list().
- add missing spinlock_unlock()
- add missing interrupts_disable() and interrupts_restore()
Coding style fixes and cleanup.
 
686 6880 d 16 h bondari /kernel/trunk/generic/ Minor changes to 'zone' command  
683 6880 d 17 h bondari /kernel/trunk/generic/ Console command 'zone' now takes zone address as parameter.
Added buddy system statistics into the 'zone' command.
 
534 6915 d 12 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.  
533 6915 d 12 h bondari /SPARTAN/trunk/ Buddy allocator for physical memory complete implementation.
Tested on IA32, AMD64, MIPS32. RWLock Test #5 is not passed.
NOTE: Other architectures could be broken (but should not be)
 
532 6915 d 12 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.  
501 6927 d 16 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel.  
490 6934 d 15 h jermar /SPARTAN/trunk/generic/src/mm/ Fix typo and clean up comments.  
489 6934 d 16 h jermar /SPARTAN/trunk/generic/ Make the buddy system more general.
Store implementation defined pointer in buddy_system_t.
Pass buddy system pointer to implementation defined buddy system operations.
 
430 6948 d 9 h jermar /SPARTAN/trunk/ Move src/ and include/ to generic.  
381 6981 d 9 h jermar /SPARTAN/trunk/ Make cross-compiler the default compiler on IA-32.
For native compilations, use ./build.ia32 native.

Small changes elsewhere.
 
379 6982 d 18 h jermar /SPARTAN/trunk/src/mm/ Optimize buddy_system_free().
Remove special-case code from the main codepath.
 
378 6982 d 19 h jermar /SPARTAN/trunk/ Redeclare eraly_malloc() with __attribute__ ((malloc)) to improve optimizations.

Reorganize #include's in scheduler.c.

Buddy system improvements.
Make buddy_system_free() explicitly invalidate order of blocks before they are coalesced.
Add some assertions.
 
377 6985 d 11 h jermar /SPARTAN/trunk/ Generic buddy allocator.
Please review the code before it is deployed.
