2188 6343 d 23 h decky /trunk/ new user space testing framework (unfinished)  
2186 6344 d 1 h decky /trunk/uspace/tester/ rename ipcc.c to tester.c  
2185 6344 d 1 h decky /trunk/ rename ipcc to tester  
2141 6353 d 14 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.		  
2128 6396 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.		  
2107 6405 d 16 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 6412 d 0 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes		  
2082 6418 d 0 h decky /trunk/ __asm__ __volatile__ -> asm volatile  
2075 6421 d 16 h jermar /trunk/uspace/libc/generic/ Remove left over debugging stuff.  
2072 6422 d 15 h jermar /trunk/uspace/libc/ Add bcmp() to libc.  
2071 6422 d 17 h jermar /trunk/ (c) versus (C)  
2070 6423 d 0 h jermar /trunk/ Rather big indentation and formatting changes.
More inteligent long line wrapping.		  
2069 6424 d 15 h jermar /trunk/ Improve formatting.  
2061 6441 d 0 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 6459 d 14 h jermar /trunk/ Coding style fixes.  
2015 6461 d 17 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 6464 d 15 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 6470 d 21 h decky /trunk/uspace/ start trivial file system driver  
2005 6470 d 22 h decky /trunk/ update rd  
1999 6473 d 2 h decky /trunk/ start RAM disk support  
1997 6476 d 18 h decky /trunk/ add version to init and boot loader  
1994 6478 d 23 h decky /trunk/ Add BGR 0888 visual for Ultra 60  
1993 6479 d 1 h decky /trunk/ make framebuffer code more generic  
1992 6479 d 2 h decky /trunk/uspace/libc/include/ add bool.h  
1971 6501 d 14 h jermar /trunk/uspace/libc/generic/ Textual changes.  
1954 6505 d 16 h jermar /trunk/ Minor changes. Some coding style fixes and also a type (tee vs. tree).
One AS -> as change.		  
1942 6513 d 16 h jermar /trunk/ Convert ia64 to the new IRQ and notification scheme.  
1939 6513 d 20 h decky /trunk/ ia32: fix compilation, keyboard not checked yet  
1938 6514 d 3 h decky /trunk/uspace/kbd/arch/mips32/src/ mips32: update kbd driver  
1931 6514 d 18 h jermar /trunk/ Add support for IPC notifications even for polled ns16550 based keyboard.  
1928 6514 d 22 h decky /trunk/ ppc32: update for new IRQ subsystem (there is still a bug left)  
1923 6515 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 6544 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 6547 d 20 h jermar /trunk/ C99 compliant header guards (hopefully) everywhere in the kernel.
Formatting and indentation changes.
Small improvements in sparc64.		  
1886 6548 d 0 h jermar /trunk/uspace/fb/ Mapping framebuffer as cacheable was identified to cause the sparc64 port not work on Sun Ultra 5.  
1880 6551 d 16 h jermar /trunk/ Small improvements here and there.  
1875 6554 d 17 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 6554 d 17 h jermar /trunk/uspace/kbd/ Cleanup and reorganize the kbd service a bit.  
1873 6554 d 17 h jermar /trunk/uspace/kbd/ sparc64 support for the kbd userspace service.  
1872 6555 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.
