2465 6209 d 23 h jermar /trunk/ Merge arm32 into trunk.  
2449 6216 d 5 h decky /trunk/uspace/rd/ remove unnecessary includes  
2445 6217 d 0 h decky /trunk/ initial merge of branches/fs
(not finished, huge cleanup is needed)
 
2443 6217 d 15 h jermar /trunk/ sscc -> suncc  
2442 6217 d 16 h jermar /trunk/ Add dummy option for Sun Studio C Compiler.
For each architecture, offer only compilers that support the target.
 
2438 6217 d 17 h decky /trunk/ update for new compiler configuration scheme  
2436 6218 d 18 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 6231 d 3 h jermar /trunk/ Improve comments for the IPC subsystem.
Fix formatting and indentation.
 
2321 6238 d 23 h decky /trunk/ keep mouse state in i8042_grab, unify keyboard and mouse IRQ handler
(this fixes ticket #12)
 
2301 6245 d 0 h decky /trunk/uspace/fb/ copy proper portion of viewport on screen border
(fixes ticket #34)
 
2230 6269 d 22 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 6270 d 0 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 6271 d 18 h decky /trunk/ make thread ID 64 bit (task ID is 64 bit already)
cleanup thread syscalls
 
2210 6271 d 20 h decky /trunk/ use more useful values  
2209 6271 d 20 h decky /trunk/uspace/ use futex instead of pthread serialization
synchronize only output to stdout
cleanup
 
2193 6272 d 23 h decky /trunk/uspace/tester/ reimplement all tests from original ipcc
(cleanup needed)
 
2192 6272 d 23 h decky /trunk/uspace/libc/arch/sparc64/include/ fix uspace atomic_add according kernel code  
2188 6273 d 0 h decky /trunk/ new user space testing framework (unfinished)  
2186 6273 d 2 h decky /trunk/uspace/tester/ rename ipcc.c to tester.c  
2185 6273 d 2 h decky /trunk/ rename ipcc to tester  
2141 6282 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 6325 d 19 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 6334 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 6341 d 0 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes
 
2082 6347 d 1 h decky /trunk/ __asm__ __volatile__ -> asm volatile  
2075 6350 d 17 h jermar /trunk/uspace/libc/generic/ Remove left over debugging stuff.  
2072 6351 d 16 h jermar /trunk/uspace/libc/ Add bcmp() to libc.  
2071 6351 d 17 h jermar /trunk/ (c) versus (C)  
2070 6352 d 1 h jermar /trunk/ Rather big indentation and formatting changes.
More inteligent long line wrapping.
 
2069 6353 d 16 h jermar /trunk/ Improve formatting.  
2061 6370 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 6388 d 15 h jermar /trunk/ Coding style fixes.  
2015 6390 d 18 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 6393 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().
