4647 5642 d 14 h jermar /branches/arm/ Branch out a new arm branch.  
4619 5651 d 13 h svoboda /trunk/uspace/srv/ns/ Move fully to IPC-based tracking of task startup and termination in NS. This also gets rid of the race condition present in the previous code.  
4618 5651 d 13 h svoboda /trunk/uspace/ Pass task ID to NS from loader. This prevents ID spoofing by user apps.  
4617 5651 d 16 h svoboda /trunk/uspace/ Allow task to return value (will be improved).  
4496 5683 d 16 h decky /trunk/uspace/ be more pedantic about undefined function prototypes (to avoid memory access traps)
add missing header files
 
4459 5684 d 14 h decky /trunk/uspace/srv/ns/ split naming service into multiple files for better readability
add support for waiting on tasks (receives kernel task notifications)
 
4253 5742 d 13 h decky /trunk/uspace/ make klog more generic  
4241 5743 d 11 h svoboda /trunk/uspace/ NS was forgetting to hangup phones. One phone was leaked for every load attempt and when all 16 phones were exhausted, NS would lock up.  
4008 5777 d 15 h decky /trunk/uspace/srv/ns/ add support for pending (blocking) connections to services
cleanup & cstyle
 
3908 5791 d 13 h decky /trunk/ overhaul pareas: use one single physical area for the physical address space not belonging to physical memory  
3904 5792 d 10 h svoboda /trunk/uspace/srv/ns/ Careful, call must be copied by value in ns.  
3896 5793 d 8 h svoboda /trunk/ More elegant way of invoking the loader - as a 'cloneable' service. Task names functionality lost for the time being.  
3083 6049 d 17 h decky /trunk/uspace/srv/ns/ service banner  
2677 6204 d 16 h jermar /trunk/ Rename IPC_M_AS_AREA_SEND to IPC_M_SHARE_OUT. Rename IPC_M_AS_AREA_RECV to
IPC_M_SHARE_IN. Provide user-friendly wrappers for these methods so that even
dummies can get it right. Some applications using simpler protocols still use
these methods directly.
 
2637 6231 d 12 h cejka /trunk/ Extended IPC_M_CONNECT_TO_ME to use 3 user defined parameters.
Phone identifier is passed in ARG5.
 
2635 6233 d 12 h cejka /trunk/ Function ipc_connect_me_to sends 3 user defined arguments now.
One argument added also to ipc_forward_fast.
Fixed devmap and improved its test.
 
2622 6241 d 18 h jermar /trunk/ Add mode argument to IPC forward.
This argument can be used to modify the way forward behaves.
 
2619 6245 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().
 
2594 6260 d 11 h cejka /trunk/uspace/ New version of device mapper.
Added devmap test to tester.
 
2588 6262 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.
 
2479 6395 d 19 h jermar /trunk/ New, better-structured, directory layout for uspace.  
2476 6398 d 11 h jermar /trunk/ Cleanup.  
2471 6401 d 13 h jermar /trunk/ Greatly improve comments in the IPC layer.
Now I think I finally start to understand our IPC internals :-)
 
2141 6483 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.
 
2071 6552 d 12 h jermar /trunk/ (c) versus (C)  
2015 6591 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.
 
2012 6594 d 10 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().
 
1880 6681 d 11 h jermar /trunk/ Small improvements here and there.  
1787 6742 d 14 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1740 6765 d 18 h jermar /uspace/trunk/ Changes to uspace doxygen comments.  
1719 6767 d 11 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
 
1649 6776 d 15 h cejka /uspace/trunk/ Doxygen comments update.  
1596 6778 d 1 h palkovsky /uspace/trunk/ Added basic klog.
Added ipc tester.
TODO: add serializing functions to psthread, so that the lines in klog won't intermix.
 
1547 6780 d 17 h palkovsky /uspace/trunk/ AS_AREA_CACHEABLE not needed anymore for sharing.
Added icons to console.
 
1531 6781 d 13 h jermar /uspace/trunk/ Cleanup of uspace.  
1501 6781 d 21 h palkovsky /uspace/trunk/ Allocation function for allocating free areas for mmap, map_physmem etc.  
1493 6782 d 8 h palkovsky /uspace/trunk/ Added support ega framebuffer.
Removed taskid parameter from map_physmem. The same effect
can (and should) be performed using IPC.
 
1462 6783 d 18 h palkovsky /uspace/trunk/ Changed according to as_area_send/recv change.  
1435 6786 d 14 h palkovsky /uspace/trunk/ Rough implementation of gettimeofday.
IPC_M_RECV_AS doesn't allow us to specify additional user parametrs. That
doesn't seem to be very configurable :-/
 
1418 6789 d 11 h jermar /uspace/trunk/ Sync with kernel.
Args for IPC_M_AS_AREA_SEND changed.
