2622 6083 d 18 h jermar /trunk/ Add mode argument to IPC forward.
This argument can be used to modify the way forward behaves.
 
2621 6085 d 16 h jermar /trunk/uspace/ Modify the async framework to make use of all six syscall arguments.
Supply user-friendly macros as in previous cases.
 
2619 6087 d 11 h jermar /trunk/ Modify ipc_answer_*() to make use of all six syscall arguments. The recommended
means of answering calls is via the ipc_answer_m() macros (where m denotes the
number of return arguments) that automatically decide between the fast register
version or the slow universal version of ipc_answer().
 
2618 6087 d 23 h jermar /trunk/ Modify asynchronous IPC to make use of all six syscall arguments. The preferred
means of asynchronous communication is now via the set of ipc_call_async_m()
macros, where m is the number of payload arguments passed to the kernel. These
macros will automatically decide between the fast and the universal slow version
of ipc_call_async.
 
2616 6088 d 16 h jermar /trunk/uspace/lib/libc/ usleep() should return int. Non-void functions really should return a value, so
fix sleep() to always return 0.
 
2615 6088 d 20 h jermar /trunk/ Modify synchronous IPC to make use of all six syscall arguments. The preferred
means of synchronous communication is now via the set of ipc_call_sync_m_n()
macros, where m is the number of payload arguments passed to the kernel and n is
the number of return values. These macros will automatically decide between the
fast and the universal slow version of ipc_call_sync.
 
2605 6091 d 16 h jermar /trunk/ Start support for six syscall arguments.
This breaks all architectures.
 
2595 6101 d 15 h jermar /trunk/uspace/lib/libc/include/libadt/ Formatting of uspace hash_table.h.  
2592 6103 d 15 h jermar /trunk/uspace/lib/libc/include/ assert.h should include stdio.h  
2588 6104 d 17 h jermar /trunk/uspace/ Add ipc_answer_fast_[01] macros so that ipc_answer_fast() users don't have to
write zero arguments all the time.
 
2586 6108 d 9 h jermar /trunk/uspace/lib/libc/ Unify implementations of TLS variant I and variant II __alloc_tls() and
__free_tls_arch().
 
2581 6110 d 11 h jermar /trunk/uspace/lib/libc/ For architectures that make use of TLS variant II (i.e. amd64, ia32 and
sparc64), fix the way TLS and TCB is allocated. Now, TLS is allocated using
memalign() with the alignment specified in _tls_alignment. Size of TLS data
itself is rounded up to be a multiple of _tls_alignment.
 
2568 6136 d 1 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.
 
2564 6136 d 2 h jermar /trunk/uspace/lib/libc/ Support for time() function.  
2550 6140 d 15 h cejka /trunk/ Fixed naming convention in IPC.  
2547 6140 d 19 h cejka /trunk/ Added basic support for device mapper.  
2541 6141 d 20 h jermar /trunk/uspace/ Header cleanup.
Move off_t, size_t and ssize_t into sys/types.h.
Get rid off the non-standard and dummy types.h.
 
2531 6150 d 12 h jermar /trunk/uspace/ VFS work.
Implement VFS_REGISTER part of the protocol in the FAT file system.

IPC work.
Rename ipc_data_send_accept() to ipc_data_receive() and ipc_data_send_answer()
to ipc_data_deliver(). Introduce ipc_data_send().
 
2529 6151 d 15 h jermar /trunk/uspace/ Turn the empty fs service into the beginning of FAT support.
Start implementing the VFS protocol for fat.c.
 
2526 6153 d 17 h jermar /trunk/uspace/ VFS work.
Delve deeper into VFS_REGISTER.
 
2525 6153 d 18 h jermar /trunk/uspace/lib/libc/include/ Implementation of isalnum().  
2524 6153 d 18 h jermar /trunk/uspace/lib/libc/include/ Implementation of isalpha().  
2522 6154 d 1 h jermar /trunk/uspace/lib/libc/ Add wrappers facilitating easy use of IPC_M_DATA_SEND calls and answers.  
2520 6155 d 13 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.
 
2486 6228 d 14 h jermar /trunk/uspace/lib/libc/ Remove duplicit and empty time.h from libc.
Move timeval functions from async.c to time.c.
 
2483 6232 d 16 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 6233 d 7 h jermar /trunk/ Goodbye pseudo threads, welcome fibrils.
The renaming might still be incomplete.
 
2481 6233 d 9 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 6237 d 19 h jermar /trunk/ New, better-structured, directory layout for uspace.  
2471 6243 d 13 h jermar /trunk/ Greatly improve comments in the IPC layer.
Now I think I finally start to understand our IPC internals :-)
 
2445 6259 d 18 h decky /trunk/ initial merge of branches/fs
(not finished, huge cleanup is needed)
 
2216 6314 d 12 h decky /trunk/ make thread ID 64 bit (task ID is 64 bit already)
cleanup thread syscalls
 
2209 6314 d 14 h decky /trunk/uspace/ use futex instead of pthread serialization
synchronize only output to stdout
cleanup
 
2188 6315 d 18 h decky /trunk/ new user space testing framework (unfinished)  
2141 6325 d 9 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 6368 d 13 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 6383 d 19 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes
 
2072 6394 d 10 h jermar /trunk/uspace/libc/ Add bcmp() to libc.  
2071 6394 d 12 h jermar /trunk/ (c) versus (C)  
2015 6433 d 12 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.
