2230 6302 d 18 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 6302 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 6304 d 15 h decky /trunk/ make thread ID 64 bit (task ID is 64 bit already)
cleanup thread syscalls
 
2209 6304 d 17 h decky /trunk/uspace/ use futex instead of pthread serialization
synchronize only output to stdout
cleanup
 
2188 6305 d 21 h decky /trunk/ new user space testing framework (unfinished)  
2141 6315 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.
 
2075 6383 d 14 h jermar /trunk/uspace/libc/generic/ Remove left over debugging stuff.  
2072 6384 d 13 h jermar /trunk/uspace/libc/ Add bcmp() to libc.  
2071 6384 d 14 h jermar /trunk/ (c) versus (C)  
2070 6384 d 22 h jermar /trunk/ Rather big indentation and formatting changes.
More inteligent long line wrapping.
 
2061 6402 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.
 
2015 6423 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 6426 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().
 
2005 6432 d 19 h decky /trunk/ update rd  
1971 6463 d 12 h jermar /trunk/uspace/libc/generic/ Textual changes.  
1923 6477 d 14 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.
 
1872 6517 d 13 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.
 
1868 6518 d 20 h jermar /trunk/ sparc64 work.
- the syscall wrapper needs to use the "memory"
clobber specifier to prevent over-optimization.
- on sparc64, the user address space spans the whole
64-bit space and therefore the macro
USER_ADDRESS_SPACE_SIZE_ARCH, as it was defined,
overflows to 0
- stop using USER_ADDRESS_SPACE_SIZE_ARCH and define
MAX_HEAP_SIZE instead
- in our situation when kernel and user address spaces
are separate, the G (global) bit cannot be used
(there is no point in it anymore)
- add the DEBUG() macro to stdio.h; DEBUG() uses
SYS_IO and is a good debugging tool for getting
early userspace to work
 
1867 6519 d 14 h jermar /trunk/uspace/ Prototype for mmap() should be in mman.h.
Anyway, is there any common sense behind naming of mman.h and mman.c?
 
1866 6519 d 14 h jermar /trunk/uspace/ Indentation and formatting facelift for libc.
Libc headers now have C99 compliant guards.
 
1863 6522 d 14 h jermar /trunk/ Allow architectures to decide between inlined and not inlined version of syscall wrapper.
Implement inlined syscall wrapper for sparc64.
 
1787 6574 d 16 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1781 6581 d 17 h jermar /uspace/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1751 6597 d 1 h palkovsky /uspace/trunk/ Sligtly more efficient ipc.  
1720 6599 d 13 h palkovsky /uspace/trunk/ Some cleanups. Martin...try make clean;make...  
1719 6599 d 14 h decky /uspace/trunk/ big code cleanup, compile with -Wall -Werror to enforce better coding
there is currently one warning that requires attention, please review
