3862 5560 d 3 h rimsky /branches/sparc/kernel/ Changed the structure of header files, which have sun4u and sun4v versions. Implemented some sun4v TSB functions.  
3343 5729 d 8 h decky /branches/sparc/ add sparc branch  
3233 5752 d 10 h decky /trunk/ remove dummy page coloring facility, which is currenty not used  
2141 6240 d 1 h jermar /trunk/ The Ultimate Solution To Illegal Virtual Aliases.
It is better to avoid them completely than to fight them.
Switch the sparc64 port to 16K pages. The TLBs and TSBs
continue to operate with 8K pages only. Page tables and
other generic parts operate with 16K pages.

Because the MMU doesn't support 16K directly, each 16K
page is emulated by a pair of 8K pages. With 16K pages,
illegal aliases cannot be created in 16K D-cache.
 
2105 6296 d 12 h decky /trunk/kernel/ move ipc structures to ipc.h  
2089 6298 d 12 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes
 
2071 6309 d 5 h jermar /trunk/ (c) versus (C)  
2048 6341 d 6 h jermar /trunk/ Formatting and indentation changes.  
2007 6356 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.
 
1978 6370 d 5 h jermar /trunk/ sparc64 code to support physical memory that starts on non-zero addresses.
Still needs to be tested on systems with such setup.
 
1857 6449 d 9 h jermar /trunk/kernel/arch/sparc64/ sparc64 work.
More bits needed to reach the userspace milestone were added.
The preemptible_handler(), still a prototype, now contains all functionality it needs.
Some sanitation was added to functions expecting page-aligned pointers to
userspace window buffer.
 
1822 6478 d 14 h jermar /trunk/ sparc64 work.
1. Formatting fixes.
2. When writing to DMMU ASI's, simple membar() can be used in place of flush().
3. Substantial changes in the way the TLB is taken over.
4. Remove unneeded functions.

This is the first revision that also runs on a real world Ultra 5 with UltraSPARC IIi
processor.

Note that 3. needs further work as the current implementation depends on the fact
that the compiler will use registers for local variables in take_over_tlb_and_tt().
Rewrite of that function into assembly is to follow.
 
1787 6499 d 7 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1780 6506 d 8 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1702 6527 d 11 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1108 6610 d 3 h jermar /kernel/trunk/ Small PTE_* macros and SET_PTL0_ADDRESS macro changes.  
977 6618 d 11 h jermar /kernel/trunk/ Add sys_mremap() syscall.  
967 6618 d 14 h palkovsky /kernel/trunk/ Allowed userspace to include page.h.  
792 6654 d 11 h jermar /kernel/trunk/ Page hash table architectures now use generic hash table to manage
mappings.
 
765 6658 d 4 h jermar /kernel/trunk/ Add PAGE_WIDTH to aid divisions by PAGE_SIZE.
