2076 6364 d 22 h jermar /trunk/kernel/ Beat the implicit illegal virtual alias created by reusing userspace frames.
In the anonymous and ELF backends, if the architecture has virtually indexed D-cache,
selectively flush cachelines belonging to the frame being freed.
This fixes Ticket #20.		  
2071 6366 d 14 h jermar /trunk/ (c) versus (C)  
2070 6366 d 22 h jermar /trunk/ Rather big indentation and formatting changes.
More inteligent long line wrapping.		  
2069 6368 d 13 h jermar /trunk/ Improve formatting.  
2068 6373 d 22 h jermar /trunk/kernel/ Formatting and indentation fixes.  
2067 6376 d 20 h jermar /trunk/kernel/ More formatting changes.  
2066 6378 d 19 h jermar /trunk/kernel/generic/src/main/ Formatting changes.
Bump year in kernel copyright.		  
2064 6380 d 13 h vana /trunk/ SIMICS added as a simulator kernel runs on  
2063 6380 d 17 h jermar /trunk/kernel/generic/src/lib/ Call big endian byte swap function instead of little endian.  
2062 6380 d 18 h jermar /trunk/kernel/generic/src/lib/ switch statement coding style fixes.  
2059 6389 d 23 h jermar /trunk/kernel/generic/ Improve indentation and formatting.

2051 6396 d 0 h decky /trunk/kernel/ quiet mode  
2050 6396 d 1 h decky /trunk/kernel/ benchmarking with statistics (initial)  
2048 6398 d 16 h jermar /trunk/ Formatting and indentation changes.  
2042 6400 d 18 h decky /trunk/kernel/ introduce uncounted threads, whose accounting doesn't affect accumulated task accounting
run tests in kconsole thread again		  
2041 6400 d 19 h decky /trunk/kernel/generic/src/proc/ revert 2040  
2040 6400 d 21 h decky /trunk/kernel/generic/src/proc/ add forgotten btree_remove()  
2039 6400 d 22 h decky /trunk/kernel/generic/ accumulate task accounting, run tests as separate kernel task  
2035 6401 d 20 h decky /trunk/kernel/generic/src/ more fancy kconsole output  
2032 6401 d 21 h decky /trunk/kernel/generic/src/proc/ proper initialization of last_cycle  
2031 6401 d 23 h decky /trunk/kernel/generic/include/proc/ fix comment  
2030 6401 d 23 h decky /trunk/kernel/ thread CPU cycles accounting  
2027 6402 d 22 h decky /trunk/kernel/ cleanup kernel tests infrastructure  
2026 6403 d 11 h jermar /trunk/kernel/generic/include/ipc/ Improve comment.  
2025 6403 d 11 h jermar /trunk/ Coding style fixes.  
2020 6403 d 16 h decky /trunk/kernel/ integrate more tests  
2019 6403 d 16 h decky /trunk/kernel/ prepare for new test infrastructure  
2015 6405 d 14 h jermar /trunk/ Rework support for virtually indexed cache.
Instead of repeatedly flushing the data cache, which was a huge overkill, refuse to create an illegal address alias
in the kernel (again) and allocate appropriate page color in userspace instead. Extend the detection also to
SYS_PHYSMEM_MAP syscall.

Add support for tracking physical memory areas mappable by SYS_PHYSMEM_MAP.

Lots of coding style changes.		  
2012 6408 d 12 h jermar /trunk/ Eliminate confusion between SYS_MAP_PHYSMEM and sys_physmem_map.
The syscall is to be called SYS_PHYSMEM_MAP from now on and the functions that participate in its implementation are
called *physmem_map().		  
2009 6410 d 13 h jermar /trunk/kernel/ Initial support for handling illegal virtual aliases on sparc64.  
2007 6413 d 13 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.		  
2005 6414 d 19 h decky /trunk/ update rd  
2004 6414 d 19 h decky /trunk/kernel/generic/include/ cleanup  
2002 6414 d 21 h decky /trunk/kernel/generic/ rd work  
2001 6416 d 12 h jermar /trunk/kernel/ Indentation and comment fixes.  
2000 6417 d 0 h decky /trunk/kernel/ move files to more proper locations  
1999 6417 d 0 h decky /trunk/ start RAM disk support  
1981 6426 d 22 h jermar /trunk/kernel/ Indentation, formatting and minor changes.  
1972 6439 d 21 h jermar /trunk/ Modify selected function to consume less stack space.

Avoid flushw instruction in the sparc64 loader.
