2138 6402 d 17 h decky /trunk/contrib/toolchain/ revert previous change (libobjc is actually HOST platform dependent)  
2137 6402 d 18 h kebrt /branches/arm/contrib/toolchain/ typo  
2136 6402 d 18 h kebrt /branches/arm/kernel/doc/ new developer  
2135 6402 d 22 h stepan /branches/arm/kernel/doc/ test commit  
2134 6403 d 18 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 6403 d 18 h jermar /trunk/kernel/generic/src/mm/ Coding style and indentation fixes.  
2132 6405 d 0 h jermar /trunk/kernel/generic/src/mm/ Fix coding style in the address space area backends.  
2131 6405 d 20 h decky /branches/ add development branches  
2130 6438 d 15 h jermar /tags/0.2.0.4/ Tagging 0.2.0.4 release.  
2129 6438 d 17 h jermar /trunk/ Fix small problem in sparc64 port.

Bump version to 0.2.0.4 (Sunset).		  
2128 6445 d 18 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.		  
2127 6446 d 4 h decky /trunk/kernel/generic/src/lib/ add forgotten implementation  
2126 6446 d 15 h decky /trunk/kernel/ small cleanup, more work coming  
2125 6446 d 17 h decky /trunk/ experimental support for Objective C
(disabled by default)		  
2124 6446 d 19 h decky /trunk/kernel/generic/ implement simple realloc()  
2123 6452 d 22 h decky /trunk/kernel/generic/src/mm/ add forgotten unsigned  
2122 6452 d 22 h decky /trunk/kernel/generic/ explicit typecast, fix signed/unsigned comparison  
2121 6452 d 22 h decky /trunk/kernel/generic/src/mm/ remove anonymous structure, add static qualifier  
2120 6452 d 22 h decky /trunk/kernel/generic/include/syscall/ specify syscall handler arguments  
2119 6452 d 22 h decky /trunk/kernel/generic/src/syscall/ explicit typecast
