2301 6217 d 5 h decky /trunk/uspace/fb/ copy proper portion of viewport on screen border
(fixes ticket #34)		  
2230 6242 d 3 h jermar /trunk/uspace/ Remove printf() serialization from thread1 test in tester.
The agreement among developers seems to be that:
- there _must_ be a futex to serialize access to printf()
- there _must_ be pseudo thread serialization in printf()
- the best place for this is vprintf(), the one that goes to console		  
2229 6242 d 5 h jermar /trunk/ Revert some of the changes introduced in revision 2209.
I think it is not correct to remove serialization of pseudo threads in printf_core.c.
With thread-level futex serialization, several pseudo threads running in one thread could easily deadlock
the task.

Add a dedicated futex serialization to thread1.c test only.		  
2216 6243 d 23 h decky /trunk/ make thread ID 64 bit (task ID is 64 bit already)
cleanup thread syscalls		  
2210 6244 d 1 h decky /trunk/ use more useful values  
2209 6244 d 1 h decky /trunk/uspace/ use futex instead of pthread serialization
synchronize only output to stdout
cleanup		  
2193 6245 d 4 h decky /trunk/uspace/tester/ reimplement all tests from original ipcc
(cleanup needed)		  
2192 6245 d 5 h decky /trunk/uspace/libc/arch/sparc64/include/ fix uspace atomic_add according kernel code  
2188 6245 d 5 h decky /trunk/ new user space testing framework (unfinished)  
2186 6245 d 7 h decky /trunk/uspace/tester/ rename ipcc.c to tester.c  
2185 6245 d 7 h decky /trunk/ rename ipcc to tester  
2141 6254 d 20 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 6298 d 0 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 6306 d 22 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 6313 d 6 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes		  
2082 6319 d 6 h decky /trunk/ __asm__ __volatile__ -> asm volatile  
2075 6322 d 22 h jermar /trunk/uspace/libc/generic/ Remove left over debugging stuff.  
2072 6323 d 22 h jermar /trunk/uspace/libc/ Add bcmp() to libc.  
2071 6323 d 23 h jermar /trunk/ (c) versus (C)  
2070 6324 d 6 h jermar /trunk/ Rather big indentation and formatting changes.
More inteligent long line wrapping.
