4605 5608 d 2 h decky /branches/snapshot/ add task snapshoting branch  
4490 5636 d 20 h decky /trunk/kernel/ remove redundant index_t and count_t types (which were always quite ambiguous and not actually needed)  
4108 5719 d 22 h decky /trunk/kernel/arch/mips32/src/mm/ remove unmaintained Simics machine (might return later)
whitespace changes
 
3973 5733 d 4 h decky /trunk/kernel/ kernel memory management revisited (phase 2): map physical memory according to zones
- ia32: register reserved and ACPI zones
- pareas are now used only for mapping of present physical memory (hw_area() is gone)
- firmware zones and physical addresses outside any zones are allowed to be mapped generally
- fix nasty antient bug in zones_insert_zone()
 
3967 5734 d 22 h decky /trunk/kernel/arch/mips32/src/mm/ remove typo  
3966 5734 d 22 h decky /trunk/kernel/arch/mips32/src/mm/ replace old ifdefs  
3910 5743 d 15 h decky /trunk/kernel/arch/mips32/ eliminate non-standard -D$(MACHINE)  
3908 5743 d 21 h decky /trunk/ overhaul pareas: use one single physical area for the physical address space not belonging to physical memory  
3880 5747 d 20 h decky /trunk/kernel/arch/ simplify configuration
introduce arch_construct_function and inb/outb (sometimes empty) on all platforms
various code cleanup
 
3236 5947 d 19 h decky /trunk/kernel/arch/mips32/src/mm/ limit physical memory to 512 MB (more cannot be used right now, see ticket #29)
fix physical memory detection in gxemul (which doesn't honor uncached flag in TLB)
 
3232 5948 d 2 h decky /trunk/kernel/arch/mips32/src/mm/ fixes  
3231 5948 d 2 h decky /trunk/kernel/arch/mips32/src/mm/ finer granularity (256 KiB)  
3230 5948 d 3 h decky /trunk/kernel/arch/mips32/ fix off-by-one bug
cleanup
 
3228 5948 d 12 h decky /trunk/ physical memory detection in MSIM (discontinous regions supported)
remove Sgi Indy (ARC) support -- it was unmaintaned, untested for years and without uspace support
 
2725 6120 d 2 h decky /trunk/kernel/ remove config.memory_size, get_memory_size() and memory_init.{c|d}
the amount of available memory can be calculated from the sizes of the zones
add FRAMES2SIZE, SIZE2KB and SIZE2MB functions/macros (code readability)
 
2722 6121 d 1 h decky /trunk/kernel/arch/mips32/ convert ARC specific commands to generic ones  
2071 6504 d 19 h jermar /trunk/ (c) versus (C)  
1787 6694 d 21 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1776 6702 d 1 h jermar /kernel/trunk/arch/mips32/ Typos and indentation fixes for mips32 and some generic files as well.  
1702 6723 d 1 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
836 6842 d 17 h palkovsky /kernel/trunk/ Added support for 24-bit framebuffer.  
815 6848 d 3 h jermar /kernel/trunk/ Fix sparc64 and ia64 to work with the changed frame allocator.

Fix ppc32 to at least compile.
 
814 6848 d 3 h palkovsky /kernel/trunk/ Cleanup o frame allocator.
Removed early_malloc & initial heap.
Will break ia64, ppc & sparc.
Added e820 table print.
 
724 6869 d 19 h palkovsky /kernel/trunk/ Commit of the falloc_bad branch to trunk (719:723).  
573 6908 d 21 h palkovsky /kernel/trunk/ Added MIPS ARC memory initializaiton.  
536 6913 d 19 h bondari /kernel/trunk/ Minor bugfix caused by invalid frame_region_not_free() usage  
534 6913 d 20 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.  
533 6913 d 20 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 6913 d 20 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.  
501 6926 d 1 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel.  
368 6988 d 2 h jermar /SPARTAN/trunk/ Physical memory management work.
New frame allocator.
Some architectures need to have bigger heap.
 
341 6997 d 2 h jermar /SPARTAN/trunk/ Rename mips port to mips32.  
329 6998 d 22 h palkovsky /SPARTAN/trunk/ Basic changes to boot it on SGI Indy.  
326 6999 d 15 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.
 
113 7094 d 15 h jermar /SPARTAN/trunk/ SMP recovery patch #2 (SMP is no longer broken !!!).
Fix missing KA2PA() operation in ap.S which was causing page faults during AP early initialization.
Fix bug in map_page_to_frame(): 'root' was interpretted as kernel address while read_dba() returns physical address.
Make references to page directory and page tables use kernel addresses instead of physical addresses.

Massive frame allocation code cleanup.
Basically revert to what we had had before implementation of userspace.

Usual cosmetics.
