2528 6128 d 18 h jermar /trunk/uspace/lib/libc/ Modify parts of the build system and libc to support building applications on
paths with differing distances from lib/libc (e.g. uspace/srv/ns and
uspace/srv/fs/fat).
 
2526 6130 d 21 h jermar /trunk/uspace/ VFS work.
Delve deeper into VFS_REGISTER.
 
2525 6130 d 22 h jermar /trunk/uspace/lib/libc/include/ Implementation of isalnum().  
2524 6130 d 22 h jermar /trunk/uspace/lib/libc/include/ Implementation of isalpha().  
2522 6131 d 5 h jermar /trunk/uspace/lib/libc/ Add wrappers facilitating easy use of IPC_M_DATA_SEND calls and answers.  
2520 6132 d 16 h jermar /trunk/uspace/ VFS work.
Turn the dummy skeleton into a dummy skeleton that can handle connections.
There are already traces of the VFS protocol.
 
2495 6195 d 20 h jermar /trunk/uspace/lib/libc/generic/io/ Formatting changes.  
2492 6201 d 18 h jermar /trunk/uspace/lib/libc/generic/ Add comment clarifying how a fibril waiting for a message gets rescheduled.  
2490 6203 d 19 h jermar /trunk/uspace/lib/libc/generic/ Improve comments in async.c  
2489 6203 d 21 h jermar /trunk/ Allow HelenOS to be built by a native gcc on Solaris.  
2488 6205 d 13 h jermar /trunk/uspace/lib/libc/generic/ Improve comments in async.c  
2486 6205 d 17 h jermar /trunk/uspace/lib/libc/ Remove duplicit and empty time.h from libc.
Move timeval functions from async.c to time.c.
 
2485 6209 d 15 h jermar /trunk/uspace/lib/libc/generic/ More fibril/psthread cleanup.  
2484 6209 d 16 h jermar /trunk/uspace/lib/libc/generic/ More psthread/fibril cleanup.  
2483 6209 d 20 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 6210 d 11 h jermar /trunk/ Goodbye pseudo threads, welcome fibrils.
The renaming might still be incomplete.
 
2481 6210 d 12 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 6214 d 22 h jermar /trunk/ New, better-structured, directory layout for uspace.  
2471 6220 d 16 h jermar /trunk/ Greatly improve comments in the IPC layer.
Now I think I finally start to understand our IPC internals :-)
 
2470 6224 d 14 h jermar /trunk/ Fix a double-free recently introduced in revision r2436.
Add a comment clarifying the life-cycle of the kernel_uarg structure.

Comment out the freeing of userspace thread stack while still running on it.
This should be fixed by implementing userspace version of thread_join().
 
2469 6224 d 15 h jermar /trunk/uspace/libc/generic/ Fix a bug in userspace thread_create() that confused success of the
syscall with failure.
 
2468 6224 d 17 h jermar /trunk/ Remove some forgotten \r from arm32 files.
Formatting changes.
Add some correct BOOT_mips32_* guards.
 
2465 6229 d 21 h jermar /trunk/ Merge arm32 into trunk.  
2445 6236 d 21 h decky /trunk/ initial merge of branches/fs
(not finished, huge cleanup is needed)
 
2438 6237 d 14 h decky /trunk/ update for new compiler configuration scheme  
2436 6238 d 16 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 6251 d 1 h jermar /trunk/ Improve comments for the IPC subsystem.
Fix formatting and indentation.
 
2230 6289 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 6289 d 22 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 6291 d 15 h decky /trunk/ make thread ID 64 bit (task ID is 64 bit already)
cleanup thread syscalls
 
2209 6291 d 18 h decky /trunk/uspace/ use futex instead of pthread serialization
synchronize only output to stdout
cleanup
 
2192 6292 d 21 h decky /trunk/uspace/libc/arch/sparc64/include/ fix uspace atomic_add according kernel code  
2188 6292 d 22 h decky /trunk/ new user space testing framework (unfinished)  
2141 6302 d 12 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 6345 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.
 
2089 6360 d 22 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes
 
2082 6366 d 22 h decky /trunk/ __asm__ __volatile__ -> asm volatile  
2075 6370 d 15 h jermar /trunk/uspace/libc/generic/ Remove left over debugging stuff.  
2072 6371 d 14 h jermar /trunk/uspace/libc/ Add bcmp() to libc.  
2071 6371 d 15 h jermar /trunk/ (c) versus (C)
