2471 6234 d 21 h jermar /trunk/ Greatly improve comments in the IPC layer.
Now I think I finally start to understand our IPC internals :-)
 
2141 6316 d 17 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 6385 d 20 h jermar /trunk/ (c) versus (C)  
2015 6424 d 20 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 6427 d 18 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 6514 d 19 h jermar /trunk/ Small improvements here and there.  
1787 6575 d 22 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1740 6599 d 2 h jermar /uspace/trunk/ Changes to uspace doxygen comments.  
1719 6600 d 20 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 6609 d 23 h cejka /uspace/trunk/ Doxygen comments update.  
1596 6611 d 9 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 6614 d 2 h palkovsky /uspace/trunk/ AS_AREA_CACHEABLE not needed anymore for sharing.
Added icons to console.
 
1531 6614 d 21 h jermar /uspace/trunk/ Cleanup of uspace.  
1501 6615 d 5 h palkovsky /uspace/trunk/ Allocation function for allocating free areas for mmap, map_physmem etc.  
1493 6615 d 16 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 6617 d 2 h palkovsky /uspace/trunk/ Changed according to as_area_send/recv change.  
1435 6619 d 22 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 6622 d 19 h jermar /uspace/trunk/ Sync with kernel.
Args for IPC_M_AS_AREA_SEND changed.
 
1392 6626 d 21 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 6630 d 19 h decky /uspace/trunk/ create special entry point for drivers (don't initialize I/O)  
1366 6630 d 20 h decky /uspace/trunk/ code cleanup (somebody should read the coding style guide)
remove __DONT_OPEN_STDIO__ (this has to be done in a different way, ppc32 linker segfaults on initiating extern variable)
remove deprecated libipc stuff
 
1365 6631 d 3 h jermar /uspace/trunk/ Sync with kernel.
Add ipc_wait_for_call_timeout() and ipc_trywait_for_call().
Modify ipc_wait_for_call() to be unconditional.
 
1363 6631 d 17 h vana /uspace/trunk/ Earliest version of Userspace Framebuffer driver, with stream support in libc.
Also Virtual framebuffers made as split on main fb and its usage by streams

(please test it and report)
 
1360 6631 d 23 h jermar /uspace/trunk/ Sync with kernel.
Rename IPC_M_AS_SEND to IPC_M_AS_AREA_SEND.
 
1353 6632 d 2 h jermar /uspace/trunk/ Fix uspace to compile again.  
1351 6632 d 3 h palkovsky /uspace/trunk/ Merge ipc and libc. Does not compile.  
1343 6632 d 7 h jermar /uspace/trunk/ Add services.h to codify service numbers.
Assign codes for PCI, keyboard and frame buffer services.

Rename ipc_answer() to ipc_answer_fast() and add the basic
slower variant and call it ipc_answer(). Add some doxygen comments.

Remove unused bits from the libpci library.
 
1338 6633 d 1 h jermar /uspace/trunk/ Fix typos and comments.  
1336 6633 d 3 h jermar /uspace/trunk/ Implement simple connect_me_to in NS.
Disambigue the term phoneid by creating new term in_phone_hash,
which in fact represents kernel address of the phone sending the
message.
 
1335 6633 d 5 h jermar /uspace/trunk/ Simple registration of services at NS.  
1330 6633 d 23 h palkovsky /uspace/trunk/ Added support to IPC for sharing pages. Remove old calls as_area_send/accept,
modify tests.
 
1285 6645 d 8 h palkovsky /uspace/trunk/ns/ Added commented example to ns.c how to access i8042 from uspace.  
1282 6645 d 19 h palkovsky /uspace/trunk/ Added way to do an action upon interrupt.
ns.c contains a commented example on how to access keyboard in msim.
 
1259 6648 d 18 h palkovsky /uspace/trunk/ Added support for irq notification registering.  
1091 6689 d 21 h palkovsky /uspace/trunk/ Adapt userspace API to conform to kernel api.  
1089 6690 d 4 h palkovsky /uspace/trunk/ More IPC added syscall for hangup and some tests.  
1073 6692 d 5 h cejka /uspace/trunk/ Userspace printf was rewritten to support standard format. Not all needed features implemented yet.  
1061 6692 d 20 h palkovsky /uspace/trunk/ Added support for ipc_connect_me_to.  
1030 6693 d 16 h palkovsky /uspace/trunk/ns/ Added missing file.  
1028 6693 d 16 h palkovsky /uspace/trunk/ Added simple testing skeleton for nameservice.
Added support for ipc_connect_to_me, some fixes.
