2144 6319 d 8 h jermar /trunk/kernel/arch/sparc64/src/mm/ Fix TSB size.  
2143 6319 d 15 h jermar /trunk/kernel/arch/sparc64/include/ Remove unneeded enum member.  
2142 6319 d 15 h jermar /trunk/kernel/generic/include/mm/ Remove out of date comment.  
2141 6320 d 7 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.
 
2134 6321 d 11 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 6321 d 11 h jermar /trunk/kernel/generic/src/mm/ Coding style and indentation fixes.  
2132 6322 d 17 h jermar /trunk/kernel/generic/src/mm/ Fix coding style in the address space area backends.  
2129 6356 d 10 h jermar /trunk/ Fix small problem in sparc64 port.

Bump version to 0.2.0.4 (Sunset).
 
2128 6363 d 11 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 6363 d 21 h decky /trunk/kernel/generic/src/lib/ add forgotten implementation  
2126 6364 d 8 h decky /trunk/kernel/ small cleanup, more work coming  
2125 6364 d 10 h decky /trunk/ experimental support for Objective C
(disabled by default)
 
2124 6364 d 12 h decky /trunk/kernel/generic/ implement simple realloc()

2111 6370 d 18 h decky /trunk/kernel/generic/src/adt/ fix signed/unsigned comparison  
2110 6371 d 9 h jermar /trunk/kernel/arch/ia64/ Minor cleanup in ia64.  
2109 6371 d 19 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 6371 d 19 h jermar /trunk/kernel/generic/src/console/ Cleanup kconsole.c  
2107 6372 d 9 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 6372 d 17 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 6376 d 18 h decky /trunk/kernel/ move ipc structures to ipc.h  
2104 6376 d 19 h decky /trunk/kernel/generic/src/lib/ more fine order of magnitude display  
2103 6377 d 10 h decky /trunk/kernel/generic/include/ move timeout_t to timeout.h
move other helper types to thread.h
