2161 6398 d 16 h jermar /trunk/kernel/arch/sparc64/src/mm/ Fix TSB bug during TSB refill.
When one wants to enable a TSB entry, he or she should set the
entry invalid bit to false, as opposed to setting it to true.

2157 6398 d 23 h jancik /branches/arm/tools/ Cygwin with TurtoiseSVN has problem with symlinks ... this script solves this.

Run this after downloading sources and before compilation.

2141 6400 d 12 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.
 
2140 6400 d 13 h decky /branches/gc/ add garbage collector branch  
2139 6400 d 13 h decky /trunk/contrib/toolchain/ move to GCC 4.1.2, make scripts really host platform independent
remove orphaned libobjc
 
2138 6400 d 16 h decky /trunk/contrib/toolchain/ revert previous change (libobjc is actually HOST platform dependent)  
2137 6400 d 16 h kebrt /branches/arm/contrib/toolchain/ typo  
2136 6400 d 16 h kebrt /branches/arm/kernel/doc/ new developer  
2135 6400 d 21 h stepan /branches/arm/kernel/doc/ test commit  
2134 6401 d 16 h jermar /trunk/kernel/ Reworked handling of illegal virtual aliases caused by frame reuse.
We moved the incomplete handling from backend's frame method to
backend's page_fault method. The page_fault method is the one that
can create an illegal alias if it writes the userspace frame using
kernel address with a different page color than the page to which is
this frame mapped in userspace. When we detect this, we do D-cache
shootdown on all processors (!!!).

If we add code that accesses userspace memory from kernel address
space, we will have to check for illegal virtual aliases at all such
places.

I tested this on a 4-way simulated E6500 and a real-world Ultra 5,
which has unfortunatelly only one processor.

This solves ticket #26.
 
2133 6401 d 17 h jermar /trunk/kernel/generic/src/mm/ Coding style and indentation fixes.  
2132 6402 d 23 h jermar /trunk/kernel/generic/src/mm/ Fix coding style in the address space area backends.  
2131 6403 d 19 h decky /branches/ add development branches  
2130 6436 d 13 h jermar /tags/0.2.0.4/ Tagging 0.2.0.4 release.  
2129 6436 d 15 h jermar /trunk/ Fix small problem in sparc64 port.

Bump version to 0.2.0.4 (Sunset).
 
2128 6443 d 17 h jermar /trunk/ Add arm32 architecture. The 32 suffix is used to specify that 16-bit Thumb
instructions are not used. The arm32 code is mostly composed of placeholders
that need to be replaced by real implementation. So far, the arm32 tree
only compiles. If run under GXEmul simulator, an infinit loop at the
kernel entry point will be entered.
