3672 5624 d 0 h jermar /trunk/ Merge sparc branch to trunk.  
3234 5755 d 4 h decky /trunk/ reintroduce support for MSIM text console in user space  
3086 5809 d 4 h decky /trunk/uspace/srv/fb/ disable kernel console output for now
(this breaks some archs)		  
2637 5991 d 0 h cejka /trunk/ Extended IPC_M_CONNECT_TO_ME to use 3 user defined parameters.
Phone identifier is passed in ARG5.		  
2619 6004 d 22 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().		  
2479 6155 d 6 h jermar /trunk/ New, better-structured, directory layout for uspace.  
2141 6242 d 20 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 6311 d 23 h jermar /trunk/ (c) versus (C)  
2025 6348 d 20 h jermar /trunk/ Coding style fixes.  
2015 6350 d 23 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.		  
1787 6502 d 1 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1561 6539 d 7 h palkovsky /uspace/trunk/fb/ Fixed incorrect compiling of fb for different archs.  
1560 6539 d 7 h vana /uspace/trunk/ fb make changes neaded by ega driver and console switching by function keys  
1547 6540 d 5 h palkovsky /uspace/trunk/ AS_AREA_CACHEABLE not needed anymore for sharing.
Added icons to console.		  
1505 6541 d 6 h palkovsky /uspace/trunk/ Added mmap, munmap calls.
Added possibility to access framebuffer using shared memory.		  
1493 6541 d 19 h palkovsky /uspace/trunk/ Added support ega framebuffer.
Removed taskid parameter from map_physmem. The same effect
can (and should) be performed using IPC.		  
1490 6541 d 21 h palkovsky /uspace/trunk/ Added very preliminary support for console on architectures
that do not support framebuffer.
