4535 5672 d 18 h jermar /trunk/uspace/lib/libc/ On condvar signal/broadcast, dequeue the waiting fibril from the waiters list.
Add FIBRIL_CONDVAR_INITIALIZE.
 
4527 5674 d 12 h jermar /trunk/uspace/lib/libc/ Condition variables for fibrils.  
4526 5675 d 10 h jermar /trunk/uspace/lib/libc/ Implement readers-writer locks for fibrils.  
4516 5677 d 8 h jermar /trunk/uspace/lib/libc/ Add simple synchronization primitives to be used with fibrils.
Provided are mutexes and dummy rwlocks.
 
4513 5678 d 10 h jermar /trunk/uspace/lib/libc/generic/ Nit.  
4510 5678 d 12 h jermar /trunk/uspace/lib/libc/generic/ A little bit of cleanup and a remedy for great confusion introduced in revision 2483.  
4509 5678 d 16 h decky /trunk/uspace/ rename libadt -> adt  
3049 6048 d 18 h decky /trunk/uspace/lib/libc/generic/ empty line remove  
2586 6265 d 7 h jermar /trunk/uspace/lib/libc/ Unify implementations of TLS variant I and variant II __alloc_tls() and
__free_tls_arch().
 
2568 6292 d 23 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 6381 d 12 h jermar /trunk/uspace/lib/libc/generic/ Add comment clarifying how a fibril waiting for a message gets rescheduled.  
2483 6389 d 14 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 6390 d 5 h jermar /trunk/ Goodbye pseudo threads, welcome fibrils.
The renaming might still be incomplete.
 
2481 6390 d 7 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 6394 d 17 h jermar /trunk/ New, better-structured, directory layout for uspace.  
2071 6551 d 9 h jermar /trunk/ (c) versus (C)  
1868 6685 d 15 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 6686 d 10 h jermar /trunk/uspace/ Indentation and formatting facelift for libc.
Libc headers now have C99 compliant guards.
 
1787 6741 d 12 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1781 6748 d 13 h jermar /uspace/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).
