2471 6195 d 4 h jermar /trunk/ Greatly improve comments in the IPC layer.
Now I think I finally start to understand our IPC internals :-)
 
2141 6277 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 6346 d 3 h jermar /trunk/ (c) versus (C)  
2015 6385 d 3 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 6388 d 1 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 6475 d 2 h jermar /trunk/ Small improvements here and there.  
1787 6536 d 5 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1740 6559 d 9 h jermar /uspace/trunk/ Changes to uspace doxygen comments.  
1719 6561 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 6570 d 6 h cejka /uspace/trunk/ Doxygen comments update.  
1596 6571 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 6574 d 8 h palkovsky /uspace/trunk/ AS_AREA_CACHEABLE not needed anymore for sharing.
Added icons to console.
 
1531 6575 d 4 h jermar /uspace/trunk/ Cleanup of uspace.  
1501 6575 d 12 h palkovsky /uspace/trunk/ Allocation function for allocating free areas for mmap, map_physmem etc.  
1493 6575 d 23 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 6577 d 9 h palkovsky /uspace/trunk/ Changed according to as_area_send/recv change.  
1435 6580 d 5 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 6583 d 2 h jermar /uspace/trunk/ Sync with kernel.
Args for IPC_M_AS_AREA_SEND changed.
 
1392 6587 d 4 h palkovsky /uspace/trunk/ Merged libadt into libc.
Made lot of psthread and thread stuff thread-safe.
Added new driver framework for easy C connection programming.
Changed FB code to use new API.
 
1367 6591 d 2 h decky /uspace/trunk/ create special entry point for drivers (don't initialize I/O)
