4535 5618 d 10 h jermar /trunk/uspace/lib/libc/ On condvar signal/broadcast, dequeue the waiting fibril from the waiters list.
Add FIBRIL_CONDVAR_INITIALIZE.
 
4527 5620 d 5 h jermar /trunk/uspace/lib/libc/ Condition variables for fibrils.  
4526 5621 d 2 h jermar /trunk/uspace/lib/libc/ Implement readers-writer locks for fibrils.  
4516 5623 d 0 h jermar /trunk/uspace/lib/libc/ Add simple synchronization primitives to be used with fibrils.
Provided are mutexes and dummy rwlocks.
 
4513 5624 d 3 h jermar /trunk/uspace/lib/libc/generic/ Nit.  
4510 5624 d 4 h jermar /trunk/uspace/lib/libc/generic/ A little bit of cleanup and a remedy for great confusion introduced in revision 2483.  
4509 5624 d 9 h decky /trunk/uspace/ rename libadt -> adt  
3049 5994 d 10 h decky /trunk/uspace/lib/libc/generic/ empty line remove  
2586 6210 d 23 h jermar /trunk/uspace/lib/libc/ Unify implementations of TLS variant I and variant II __alloc_tls() and
__free_tls_arch().
 
2568 6238 d 15 h jermar /trunk/uspace/ Rename fibril_schedule_next_adv() to fibril_switch(). Rename
fibril_schedule_next() to fibril_yield(). Some fibril structures could be
uninitialized, set them to zero in fibril_setup(). For some fibrils, the stack
member can be NULL (e.g. every thread's first/main fibril); don't do free on
these stacks when cleaning up after a dead fibril.
 
2492 6327 d 5 h jermar /trunk/uspace/lib/libc/generic/ Add comment clarifying how a fibril waiting for a message gets rescheduled.  
2483 6335 d 6 h jermar /trunk/uspace/lib/libc/ Remove fibril_join().
We cannot guarantee our assumptions that easily.
This broken feature is removed instead of fixing because there are now users of it.
 
2482 6335 d 21 h jermar /trunk/ Goodbye pseudo threads, welcome fibrils.
The renaming might still be incomplete.
 
2481 6335 d 23 h jermar /trunk/uspace/lib/libc/ 1. Implement simple joining of pseudo threads. Only one pseudo thread is allowed to join another pseudo
thread. The restriction is that both pseudo threads must be from the same thread (this is to simplify
synchronization). The joiner doesn't free anything from the joinee. It only gets its return value. Not
tested thoroughly yet.

2. Cleanup of a dead pseudo thread is done by the next scheduled pseudo thread. Not tested thoroughly yet.
 
2479 6340 d 9 h jermar /trunk/ New, better-structured, directory layout for uspace.  
2071 6497 d 2 h jermar /trunk/ (c) versus (C)  
1868 6631 d 7 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
 
1866 6632 d 2 h jermar /trunk/uspace/ Indentation and formatting facelift for libc.
Libc headers now have C99 compliant guards.
 
1787 6687 d 4 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1781 6694 d 5 h jermar /uspace/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1720 6712 d 1 h palkovsky /uspace/trunk/ Some cleanups. Martin...try make clean;make...  
1719 6712 d 1 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
 
1709 6712 d 10 h jermar /uspace/trunk/ Fix some broken doxygen comments.  
1653 6721 d 3 h cejka /uspace/trunk/ Doxygen comments.  
1614 6722 d 6 h palkovsky /uspace/trunk/libc/generic/ Fixed bad TLS BSS initialization.  
1610 6722 d 7 h palkovsky /uspace/trunk/ Revised ipc. Now it is preferrable to use only functions from async.h, they
take care of correct buffering, waiting for answers etc.
 
1427 6732 d 0 h palkovsky /uspace/trunk/ Added functions to async framework for reasonable sending asynchronous
messages.
 
1407 6736 d 11 h palkovsky /uspace/trunk/libc/ Small updates to asynchronous framework.  
1392 6738 d 3 h palkovsky /uspace/trunk/ Merged libadt into libc.
Made lot of psthread and thread stuff thread-safe.
Added new driver framework for easy C connection programming.
Changed FB code to use new API.
 
1155 6780 d 10 h vana /uspace/trunk/libc/ psthread RSE support  
1129 6796 d 8 h palkovsky /uspace/trunk/ Completed support for TLS in GCC (modifier __thread) for ia32,amd64,ia64 and mips.  
1128 6796 d 8 h jermar /uspace/trunk/ Improve comments in psthread.c
Rename pt->list to pt->link.
Rename ps_preempt() to psthread_schedule_next().
Rename ps_join() to psthread_join().
 
1125 6796 d 11 h jermar /uspace/trunk/ TLS and pseudo thread support for ia64.  
1113 6797 d 12 h palkovsky /uspace/trunk/ Added symbolic links 'libarch','libadt','libipc' into libc/include,
so that it can be easily used from anywhere.
Renamed thread_main to __thread_main.
Allowed MIPS to compile with -O0.
Added non-preemptible threads support (not yet secured by futexes).
Added simple way to hold Thread Local Storage. Support for compiler
will be added later.
This update breaks IA64 uspace.

There is some forgotten spinlock_lock() in futexes, amd64 gets locked
in the secod uspace thread probably with preemption disabled.
