2140 6272 d 12 h decky /branches/gc/ add garbage collector branch  
2128 6315 d 15 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.
 
2107 6324 d 13 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.
 
2089 6330 d 21 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes
 
2082 6336 d 21 h decky /trunk/ __asm__ __volatile__ -> asm volatile  
2075 6340 d 14 h jermar /trunk/uspace/libc/generic/ Remove left over debugging stuff.  
2072 6341 d 13 h jermar /trunk/uspace/libc/ Add bcmp() to libc.  
2071 6341 d 14 h jermar /trunk/ (c) versus (C)  
2070 6341 d 21 h jermar /trunk/ Rather big indentation and formatting changes.
More inteligent long line wrapping.
 
2069 6343 d 12 h jermar /trunk/ Improve formatting.  
2061 6359 d 21 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 6378 d 11 h jermar /trunk/ Coding style fixes.  
2015 6380 d 14 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 6383 d 12 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().
 
2006 6389 d 19 h decky /trunk/uspace/ start trivial file system driver  
2005 6389 d 19 h decky /trunk/ update rd  
1999 6392 d 0 h decky /trunk/ start RAM disk support  
1997 6395 d 15 h decky /trunk/ add version to init and boot loader  
1994 6397 d 21 h decky /trunk/ Add BGR 0888 visual for Ultra 60  
1993 6397 d 22 h decky /trunk/ make framebuffer code more generic  
1992 6397 d 23 h decky /trunk/uspace/libc/include/ add bool.h  
1971 6420 d 12 h jermar /trunk/uspace/libc/generic/ Textual changes.  
1954 6424 d 13 h jermar /trunk/ Minor changes. Some coding style fixes and also a type (tee vs. tree).
One AS -> as change.
 
1942 6432 d 14 h jermar /trunk/ Convert ia64 to the new IRQ and notification scheme.  
1939 6432 d 18 h decky /trunk/ ia32: fix compilation, keyboard not checked yet  
1938 6433 d 1 h decky /trunk/uspace/kbd/arch/mips32/src/ mips32: update kbd driver  
1931 6433 d 15 h jermar /trunk/ Add support for IPC notifications even for polled ns16550 based keyboard.  
1928 6433 d 19 h decky /trunk/ ppc32: update for new IRQ subsystem (there is still a bug left)  
1923 6434 d 14 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 6462 d 23 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 6466 d 17 h jermar /trunk/ C99 compliant header guards (hopefully) everywhere in the kernel.
Formatting and indentation changes.
Small improvements in sparc64.
 
1886 6466 d 22 h jermar /trunk/uspace/fb/ Mapping framebuffer as cacheable was identified to cause the sparc64 port not work on Sun Ultra 5.  
1880 6470 d 13 h jermar /trunk/ Small improvements here and there.  
1875 6473 d 15 h jermar /trunk/ sparc64 work.
- Changes to enable userspace keyboard drivers.
- Fix z8530 initialization (i.e. clear any pending Tx interrupts).
- Experimental support for framebuffers with inverted colors.
 
1874 6473 d 15 h jermar /trunk/uspace/kbd/ Cleanup and reorganize the kbd service a bit.  
1873 6473 d 15 h jermar /trunk/uspace/kbd/ sparc64 support for the kbd userspace service.  
1872 6474 d 13 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.
 
1871 6475 d 1 h jermar /trunk/ Replace FB_BIG_ENDIAN with FB_INVERT_ENDIAN.
Omit tests for architecture endianness in deciding framebuffer endianness.
 
1869 6475 d 18 h jermar /trunk/ Pass "fb.bpp-align" property to userspace so that our fb task works properly even on
framebuffers used in some Sun hardware.
 
1868 6475 d 20 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
