2622 6026 d 10 h jermar /trunk/ Add mode argument to IPC forward.
This argument can be used to modify the way forward behaves.
 
2619 6030 d 3 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 6045 d 3 h cejka /trunk/uspace/ New version of device mapper.
Added devmap test to tester.
 
2588 6047 d 9 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 6180 d 11 h jermar /trunk/ New, better-structured, directory layout for uspace.  
2476 6183 d 3 h jermar /trunk/ Cleanup.  
2471 6186 d 5 h jermar /trunk/ Greatly improve comments in the IPC layer.
Now I think I finally start to understand our IPC internals :-)
 
2141 6268 d 0 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 6337 d 4 h jermar /trunk/ (c) versus (C)  
2015 6376 d 4 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 2 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 6466 d 3 h jermar /trunk/ Small improvements here and there.  
1787 6527 d 6 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1740 6550 d 10 h jermar /uspace/trunk/ Changes to uspace doxygen comments.  
1719 6552 d 3 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 6561 d 7 h cejka /uspace/trunk/ Doxygen comments update.  
1596 6562 d 16 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 6565 d 9 h palkovsky /uspace/trunk/ AS_AREA_CACHEABLE not needed anymore for sharing.
Added icons to console.
 
1531 6566 d 5 h jermar /uspace/trunk/ Cleanup of uspace.  
1501 6566 d 13 h palkovsky /uspace/trunk/ Allocation function for allocating free areas for mmap, map_physmem etc.
