3973 5591 d 19 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()
 
3908 5602 d 11 h decky /trunk/ overhaul pareas: use one single physical area for the physical address space not belonging to physical memory  
3857 5616 d 12 h decky /trunk/ very experimental TLB refill for ppc32  
3837 5618 d 17 h decky /trunk/kernel/arch/ppc32/ use pseudorandom generator to avoid even the longest path of livelock collisions  
3830 5620 d 12 h decky /trunk/kernel/arch/ppc32/ ppc32: add support for cache disable page access control  
3233 5806 d 15 h decky /trunk/ remove dummy page coloring facility, which is currenty not used  
3071 5860 d 15 h decky /trunk/kernel/ reflect changes in generic code
proper formatting directives
coding style
 
2725 5978 d 16 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)
 
2723 5979 d 14 h decky /trunk/kernel/arch/ remove memory_print_map(), as it duplicates functionality of physmem_print()  
2721 5979 d 16 h decky /trunk/kernel/ convert e820list to a generic physmem command  
2467 6216 d 13 h jermar /trunk/ Improve comments for arch-specific implementations of hierarchical
4-level page tables. Improve formatting.
 
2465 6221 d 15 h jermar /trunk/ Merge arm32 into trunk.  
2089 6352 d 17 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes
 
2071 6363 d 10 h jermar /trunk/ (c) versus (C)  
2007 6410 d 8 h jermar /trunk/kernel/ Introduce page colors. So far, only sparc64 uses correct page color bits. Other architectures have a dummy define
specifying zero bits for a page color.

There is a new check of page color in as_area_share(). Because of lack of support for this in the userspace, the
check has been #ifef'ed out.
 
1891 6484 d 8 h jermar /trunk/kernel/ sparc64 work:
- Experimental support for TSB (Translation Storage Buffer).
 
1890 6484 d 19 h jermar /trunk/ - Create a dedicated slab cache for as_t objects and switch from malloc/free to slab_alloc/slab_free for
them.

- Slightly fix and improve both the kernel and userspace atomic_add() on sparc64.

- More TSB work on the sparc64 front.
 
1889 6485 d 10 h jermar /trunk/kernel/ Fix bug in mm/as.c:
- as_area_destroy() should not work with AS but as

sparc64 work:
- start implementing TSB support
 
1888 6488 d 13 h jermar /trunk/ C99 compliant header guards (hopefully) everywhere in the kernel.
Formatting and indentation changes.
Small improvements in sparc64.
 
1787 6553 d 12 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot
