2568 6079 d 0 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 6079 d 0 h jermar /trunk/uspace/lib/libc/ Support for time() function.  
2550 6083 d 14 h cejka /trunk/ Fixed naming convention in IPC.  
2547 6083 d 17 h cejka /trunk/ Added basic support for device mapper.  
2541 6084 d 18 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 6093 d 11 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 6094 d 13 h jermar /trunk/uspace/ Turn the empty fs service into the beginning of FAT support.
Start implementing the VFS protocol for fat.c.
 
2526 6096 d 16 h jermar /trunk/uspace/ VFS work.
Delve deeper into VFS_REGISTER.
 
2525 6096 d 17 h jermar /trunk/uspace/lib/libc/include/ Implementation of isalnum().  
2524 6096 d 17 h jermar /trunk/uspace/lib/libc/include/ Implementation of isalpha().  
2522 6097 d 0 h jermar /trunk/uspace/lib/libc/ Add wrappers facilitating easy use of IPC_M_DATA_SEND calls and answers.  
2520 6098 d 12 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 6171 d 13 h jermar /trunk/uspace/lib/libc/ Remove duplicit and empty time.h from libc.
Move timeval functions from async.c to time.c.
 
2483 6175 d 15 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 6176 d 6 h jermar /trunk/ Goodbye pseudo threads, welcome fibrils.
The renaming might still be incomplete.
 
2481 6176 d 8 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 6180 d 17 h jermar /trunk/ New, better-structured, directory layout for uspace.  
2471 6186 d 11 h jermar /trunk/ Greatly improve comments in the IPC layer.
Now I think I finally start to understand our IPC internals :-)
 
2445 6202 d 17 h decky /trunk/ initial merge of branches/fs
(not finished, huge cleanup is needed)
 
2216 6257 d 11 h decky /trunk/ make thread ID 64 bit (task ID is 64 bit already)
cleanup thread syscalls
 
2209 6257 d 13 h decky /trunk/uspace/ use futex instead of pthread serialization
synchronize only output to stdout
cleanup
 
2188 6258 d 17 h decky /trunk/ new user space testing framework (unfinished)  
2141 6268 d 7 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 6311 d 12 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 6326 d 18 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes
 
2072 6337 d 9 h jermar /trunk/uspace/libc/ Add bcmp() to libc.  
2071 6337 d 10 h jermar /trunk/ (c) versus (C)  
2015 6376 d 11 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 6379 d 9 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().
 
1999 6387 d 20 h decky /trunk/ start RAM disk support  
1992 6393 d 20 h decky /trunk/uspace/libc/include/ add bool.h  
1923 6430 d 10 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.
 
1868 6471 d 16 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 6472 d 10 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 6472 d 11 h jermar /trunk/uspace/ Indentation and formatting facelift for libc.
Libc headers now have C99 compliant guards.
 
1863 6475 d 10 h jermar /trunk/ Allow architectures to decide between inlined and not inlined version of syscall wrapper.
Implement inlined syscall wrapper for sparc64.
 
1787 6527 d 13 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1781 6534 d 14 h jermar /uspace/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1719 6552 d 10 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
 
1707 6553 d 11 h palkovsky /uspace/trunk/ Added mouse input. Still missing support in console and framebuffer.
