2128 6332 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.		  
2089 6347 d 23 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes		  
2082 6353 d 23 h decky /trunk/ __asm__ __volatile__ -> asm volatile  
2075 6357 d 16 h jermar /trunk/uspace/libc/generic/ Remove left over debugging stuff.  
2072 6358 d 15 h jermar /trunk/uspace/libc/ Add bcmp() to libc.  
2071 6358 d 16 h jermar /trunk/ (c) versus (C)  
2070 6359 d 0 h jermar /trunk/ Rather big indentation and formatting changes.
More inteligent long line wrapping.		  
2061 6376 d 23 h jermar /trunk/ Improve comments and fix formatting in (sparc64) TLS implementation.
Improve some comments and formatting in sparc64 uspace thread library
code.

Update required msim version.		  
2025 6395 d 13 h jermar /trunk/ Coding style fixes.  
2015 6397 d 16 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 6400 d 14 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().		  
2005 6406 d 21 h decky /trunk/ update rd  
1999 6409 d 2 h decky /trunk/ start RAM disk support  
1992 6415 d 1 h decky /trunk/uspace/libc/include/ add bool.h  
1971 6437 d 14 h jermar /trunk/uspace/libc/generic/ Textual changes.  
1923 6451 d 16 h jermar /trunk/ Replace the old IRQ dispatcher and IPC notifier with new implementation.
Note that all architectures except for sparc64 are now broken
and don't even compile.		  
1890 6480 d 1 h jermar /trunk/ - Create a dedicated slab cache for as_t objects and switch from malloc/free to slab_alloc/slab_free for
them.

- Slightly fix and improve both the kernel and userspace atomic_add() on sparc64.

- More TSB work on the sparc64 front.		  
1888 6483 d 20 h jermar /trunk/ C99 compliant header guards (hopefully) everywhere in the kernel.
Formatting and indentation changes.
Small improvements in sparc64.		  
1872 6491 d 15 h jermar /trunk/uspace/libc/generic/io/ read() and write() now check if the virtual function they want to
call exists. Thus, these calls will not kill the whole task
if called for instance from a driver task but gracefully fail.		  
1868 6492 d 22 h jermar /trunk/ sparc64 work.
- the syscall wrapper needs to use the "memory"
clobber specifier to prevent over-optimization.
- on sparc64, the user address space spans the whole
64-bit space and therefore the macro
USER_ADDRESS_SPACE_SIZE_ARCH, as it was defined,
overflows to 0
- stop using USER_ADDRESS_SPACE_SIZE_ARCH and define
MAX_HEAP_SIZE instead
- in our situation when kernel and user address spaces
are separate, the G (global) bit cannot be used
(there is no point in it anymore)
- add the DEBUG() macro to stdio.h; DEBUG() uses
SYS_IO and is a good debugging tool for getting
early userspace to work
