2465 6172 d 20 h jermar /trunk/ Merge arm32 into trunk.  
2449 6179 d 2 h decky /trunk/uspace/rd/ remove unnecessary includes  
2445 6179 d 21 h decky /trunk/ initial merge of branches/fs
(not finished, huge cleanup is needed)
 
2443 6180 d 12 h jermar /trunk/ sscc -> suncc  
2442 6180 d 13 h jermar /trunk/ Add dummy option for Sun Studio C Compiler.
For each architecture, offer only compilers that support the target.
 
2438 6180 d 14 h decky /trunk/ update for new compiler configuration scheme  
2436 6181 d 15 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 6194 d 0 h jermar /trunk/ Improve comments for the IPC subsystem.
Fix formatting and indentation.
 
2321 6201 d 20 h decky /trunk/ keep mouse state in i8042_grab, unify keyboard and mouse IRQ handler
(this fixes ticket #12)
 
2301 6207 d 21 h decky /trunk/uspace/fb/ copy proper portion of viewport on screen border
(fixes ticket #34)
 
2230 6232 d 19 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 6232 d 21 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 6234 d 15 h decky /trunk/ make thread ID 64 bit (task ID is 64 bit already)
cleanup thread syscalls
 
2210 6234 d 17 h decky /trunk/ use more useful values  
2209 6234 d 17 h decky /trunk/uspace/ use futex instead of pthread serialization
synchronize only output to stdout
cleanup
 
2193 6235 d 20 h decky /trunk/uspace/tester/ reimplement all tests from original ipcc
(cleanup needed)
 
2192 6235 d 20 h decky /trunk/uspace/libc/arch/sparc64/include/ fix uspace atomic_add according kernel code  
2188 6235 d 21 h decky /trunk/ new user space testing framework (unfinished)  
2186 6235 d 22 h decky /trunk/uspace/tester/ rename ipcc.c to tester.c  
2185 6235 d 22 h decky /trunk/ rename ipcc to tester  
2141 6245 d 11 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 6288 d 16 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 6297 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 6303 d 21 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes
 
2082 6309 d 22 h decky /trunk/ __asm__ __volatile__ -> asm volatile  
2075 6313 d 14 h jermar /trunk/uspace/libc/generic/ Remove left over debugging stuff.  
2072 6314 d 13 h jermar /trunk/uspace/libc/ Add bcmp() to libc.  
2071 6314 d 14 h jermar /trunk/ (c) versus (C)  
2070 6314 d 22 h jermar /trunk/ Rather big indentation and formatting changes.
More inteligent long line wrapping.
 
2069 6316 d 13 h jermar /trunk/ Improve formatting.  
2061 6332 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 6351 d 12 h jermar /trunk/ Coding style fixes.  
2015 6353 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 6356 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().
