2445 6185 d 18 h decky /trunk/ initial merge of branches/fs
(not finished, huge cleanup is needed)
 
2438 6186 d 11 h decky /trunk/ update for new compiler configuration scheme  
2436 6187 d 13 h jermar /trunk/ Fix two memory leaks.

In kernel, kernel_uarg structure needs to be deallocated when a thread
with userspace context is destroyed.

In userspace, the return value of the SYS_THREAD_CREATE must be checked
for error conditions and in case of error, uarg and stack must be freed
up.
 
2359 6199 d 22 h jermar /trunk/ Improve comments for the IPC subsystem.
Fix formatting and indentation.
 
2230 6238 d 16 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 6238 d 19 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 6240 d 12 h decky /trunk/ make thread ID 64 bit (task ID is 64 bit already)
cleanup thread syscalls
 
2209 6240 d 15 h decky /trunk/uspace/ use futex instead of pthread serialization
synchronize only output to stdout
cleanup
 
2192 6241 d 18 h decky /trunk/uspace/libc/arch/sparc64/include/ fix uspace atomic_add according kernel code  
2188 6241 d 19 h decky /trunk/ new user space testing framework (unfinished)  
2141 6251 d 9 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 6294 d 13 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 6309 d 19 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes
 
2082 6315 d 19 h decky /trunk/ __asm__ __volatile__ -> asm volatile  
2075 6319 d 12 h jermar /trunk/uspace/libc/generic/ Remove left over debugging stuff.  
2072 6320 d 11 h jermar /trunk/uspace/libc/ Add bcmp() to libc.  
2071 6320 d 12 h jermar /trunk/ (c) versus (C)  
2070 6320 d 20 h jermar /trunk/ Rather big indentation and formatting changes.
More inteligent long line wrapping.
 
2061 6338 d 19 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 6357 d 9 h jermar /trunk/ Coding style fixes.
