2311 6232 d 7 h dobias /branches/gc/kernel/doc/ test commit  
2140 6273 d 20 h decky /branches/gc/ add garbage collector branch  
2139 6273 d 20 h decky /trunk/contrib/toolchain/ move to GCC 4.1.2, make scripts really host platform independent
remove orphaned libobjc
 
2138 6273 d 22 h decky /trunk/contrib/toolchain/ revert previous change (libobjc is actually HOST platform dependent)  
2134 6274 d 23 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 6274 d 23 h jermar /trunk/kernel/generic/src/mm/ Coding style and indentation fixes.  
2132 6276 d 6 h jermar /trunk/kernel/generic/src/mm/ Fix coding style in the address space area backends.  
2129 6309 d 22 h jermar /trunk/ Fix small problem in sparc64 port.

Bump version to 0.2.0.4 (Sunset).
 
2128 6316 d 23 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 6317 d 9 h decky /trunk/kernel/generic/src/lib/ add forgotten implementation  
2126 6317 d 20 h decky /trunk/kernel/ small cleanup, more work coming  
2125 6317 d 23 h decky /trunk/ experimental support for Objective C
(disabled by default)
 
2124 6318 d 0 h decky /trunk/kernel/generic/ implement simple realloc()  
2123 6324 d 3 h decky /trunk/kernel/generic/src/mm/ add forgotten unsigned  
2122 6324 d 3 h decky /trunk/kernel/generic/ explicit typecast, fix signed/unsigned comparison  
2121 6324 d 3 h decky /trunk/kernel/generic/src/mm/ remove anonymous structure, add static qualifier

2111 6324 d 6 h decky /trunk/kernel/generic/src/adt/ fix signed/unsigned comparison  
2110 6324 d 22 h jermar /trunk/kernel/arch/ia64/ Minor cleanup in ia64.  
2109 6325 d 7 h jermar /trunk/kernel/generic/ Revert thread_interrupt_sleep() to waitq_interrupt_sleep().
I'd prefer that this, IMO, waitq related stuff stays together.
 
2108 6325 d 7 h jermar /trunk/kernel/generic/src/console/ Cleanup kconsole.c  
2107 6325 d 21 h jermar /trunk/ When clock() is called by an external interrupt dispatched by the IRQ dispatcher,
no spinlock can be held or the kernel will not be preemptive. This fixes Ticket #24.

Formating and indentation fixes.
 
2106 6326 d 5 h jermar /trunk/kernel/ Merge as_t structure into one and leave the differring parts in as_genarch_t.

Indentation and formatting changes in header files.
 
2105 6330 d 6 h decky /trunk/kernel/ move ipc structures to ipc.h  
2104 6330 d 7 h decky /trunk/kernel/generic/src/lib/ more fine order of magnitude display  
2103 6330 d 23 h decky /trunk/kernel/generic/include/ move timeout_t to timeout.h
move other helper types to thread.h
 
2102 6330 d 23 h decky /trunk/kernel/genarch/src/fb/ signed/unsigned comparison, explicit typecast

2100 6331 d 0 h decky /trunk/kernel/ signed/unsigned comparison, explicit typecast
