4490 5477 d 6 h decky /trunk/kernel/ remove redundant index_t and count_t types (which were always quite ambiguous and not actually needed)  
3973 5573 d 14 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()		  
3940 5580 d 8 h decky /trunk/kernel/ make hw_area API more generic
this allows mapping of EGA VRAM on ia32/amd64		  
3908 5584 d 6 h decky /trunk/ overhaul pareas: use one single physical area for the physical address space not belonging to physical memory  
3778 5627 d 11 h jermar /trunk/kernel/arch/ia64/include/mm/ Extern declaration for ia64 last_frame.  
3774 5628 d 10 h jermar /trunk/kernel/arch/ia64/include/ More of ia64 cleanup.  
3635 5667 d 5 h vana /trunk/ IA64: Userspace I/O support  
3578 5681 d 17 h vana /trunk/ Alfa of SMP support on IA64  
3233 5788 d 10 h decky /trunk/ remove dummy page coloring facility, which is currenty not used  
2726 5957 d 15 h vana /trunk/ Basic IA64 boot and kernel suport for real machines  
2725 5960 d 11 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)		  
2721 5961 d 11 h decky /trunk/kernel/ convert e820list to a generic physmem command  
2089 6334 d 12 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes		  
2082 6340 d 12 h decky /trunk/ __asm__ __volatile__ -> asm volatile  
2071 6345 d 5 h jermar /trunk/ (c) versus (C)  
2007 6392 d 3 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 6466 d 3 h jermar /trunk/kernel/ sparc64 work:
- Experimental support for TSB (Translation Storage Buffer).		  
1890 6466 d 13 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 6467 d 5 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 6470 d 8 h jermar /trunk/ C99 compliant header guards (hopefully) everywhere in the kernel.
Formatting and indentation changes.
Small improvements in sparc64.
