1896 6492 d 2 h jermar /trunk/ Convert sparc64 to detect keyboard and determine
its physical address by walking the memory representation
of the OpenFirmware device tree.

Add bus-specific functions that know how to apply the
"ranges" property to one component of the "reg" property.
Buses supported so far include FHC, EBUS and PCI.		  
1787 6565 d 5 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1780 6572 d 6 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1757 6586 d 11 h jermar /kernel/trunk/ Cleanup of comments.  
1708 6590 d 12 h jermar /kernel/trunk/ Fix some broken doxygen comments.  
1702 6593 d 9 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1612 6600 d 8 h jermar /kernel/trunk/generic/src/lib/ Generic version of memcpy that is resistent towards unaligned memory accesses.  
1425 6610 d 3 h jermar /kernel/trunk/generic/ Make address space backend data a union.  
1424 6610 d 6 h jermar /kernel/trunk/ Move the sharing functionality to address space area backends.
Add backend for continuous regions of physical memory.
Sharing for these areas works automagically now.		  
1423 6610 d 10 h jermar /kernel/trunk/ Update page fault handlers to distinguish between different access modes that had caused the page fault.  
1411 6613 d 6 h jermar /kernel/trunk/ Modify the hierarchy of page fault handlers to pass access mode that caused the fault.
Architectures are required to pass either PF_ACCESS_READ, PF_ACCESS_WRITE or PF_ACCESS_EXEC
to as_page_fault(), depending on the cause of the fault.		  
1409 6614 d 0 h jermar /kernel/trunk/generic/ Some shared memory stuff (not completed).
Support for address space area backends.
Add ELF and anonymous memory backends.		  
1264 6636 d 11 h jermar /kernel/trunk/generic/ Improve Doxygen-comments.  
1248 6640 d 6 h jermar /kernel/trunk/ Add some @file doxygen comments and improve already existing comments.  
1239 6641 d 5 h jermar /kernel/trunk/generic/ Prevent race in as_area_send() by allowing the address space area to be
created with AS_AREA_ATTR_PARTIAL attribute.		  
1196 6651 d 10 h cejka /kernel/trunk/ Printf ported back from uspace to kernel.
Printf calls changed to match new conventions.		  
1100 6678 d 3 h palkovsky /kernel/trunk/ Cleanup of spinlocks, now compiles both ia32 and amd64 with
and without DEBUG_SPINLOCKS. Made spinlocks inline.
Moved syscall_handler to generic (it was identical for ia32,amd64 & mips32).
Made slightly faster syscall for ia32.
Made better interrupt routines for ia32.
Allow not saving non-scratch registers during interrupt on ia32,amd64,mips32.
Aligned interrupt handlers on ia32,amd64, this should prevent problems
with different instruction lengths.		  
1070 6681 d 13 h jermar /kernel/trunk/ More checks for address space area conflicts.  
1048 6682 d 9 h jermar /kernel/trunk/generic/ Restore interrupts when failing in as_remap().
Add check_area_conflicts() that checks whether address area overlaps with other areas.
Refuse to create writeable executable address space areas.
Rename as_area_t::size to as_area_t::pages.		  
1026 6682 d 23 h jermar /kernel/trunk/generic/ Support only anonymous address space areas.  
973 6684 d 11 h palkovsky /kernel/trunk/generic/ Added simpler userspace starting.  
963 6685 d 2 h jermar /kernel/trunk/generic/src/lib/ Fix bug in loading ELF segment.  
952 6685 d 7 h jermar /kernel/trunk/ Support for loading segments containing .bss section.  
938 6686 d 5 h jermar /kernel/trunk/ Basic support for loading ELF object files.
ia64, amd64, ia32 working.
mips32 requires some attention.		  
910 6693 d 10 h bondari /kernel/trunk/ ELF framework for all archs. SPARC V9 not tested to compile.  
882 6700 d 11 h jermar /kernel/trunk/generic/src/lib/ Improved version of generic memcpy().
Should improve frame buffer impression.		  
854 6707 d 5 h bondari /kernel/trunk/ ELF loading workaround: some core declarations.  
822 6718 d 0 h palkovsky /kernel/trunk/ Changed malloc to include second parameter and documented
recommended usage.
Added zone merging, made ia32 & amd64 to merge found zones.		  
814 6718 d 11 h palkovsky /kernel/trunk/ Cleanup o frame allocator.
Removed early_malloc & initial heap.
Will break ia64, ppc & sparc.
Added e820 table print.		  
788 6721 d 5 h jermar /kernel/trunk/ Move list and fifo data types to adt/.  
659 6766 d 12 h jermar /kernel/trunk/ Make the kernel compile with -Wall.  
635 6771 d 23 h palkovsky /kernel/trunk/ Fixed kconsole resolution of similar commands.
Add commands to debugger to allow for simple profiling or
calling debug actions if needed.		  
631 6773 d 2 h palkovsky /kernel/trunk/ Fixed cpu halting in debug panic mode.  
615 6775 d 12 h palkovsky /kernel/trunk/ Cleanups to make it compile with -Wall. Did not catch everything yet.  
609 6776 d 6 h palkovsky /kernel/trunk/ added support for breakpoints to mips32  
607 6776 d 7 h palkovsky /kernel/trunk/ Fixed weird simics panic.
Run kconsole, if we panic. This currently works in gxemul,
simics. In mips we need to modify the simulator.
On ia32 we need a function, that would speak directly to the chip
and fetch the character using polling.		  
603 6777 d 1 h palkovsky /kernel/trunk/generic/src/ Added set4 command.  
601 6777 d 3 h palkovsky /kernel/trunk/ Added some readline functionality to kconsole.
Arrows editing, history, tab completion.		  
591 6778 d 5 h palkovsky /kernel/trunk/generic/src/ Fixes in new console.  
585 6778 d 7 h palkovsky /kernel/trunk/generic/ String constants without spaces are now supported by call commands.
For more we would need some lexer.
The call? commands are not compatibile with stdarg functions on AMD
architectures, because of the calling sequence.
