2272 6304 d 1 h jermar /trunk/kernel/ Indentation and formatting fixes.  
2185 6317 d 8 h decky /trunk/ rename ipcc to tester  
2184 6317 d 10 h decky /trunk/kernel/generic/src/lib/ add zetta (sextillion) prefix
make constants explicitly unsigned		  
2141 6326 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.		  
2127 6370 d 10 h decky /trunk/kernel/generic/src/lib/ add forgotten implementation  
2126 6370 d 21 h decky /trunk/kernel/ small cleanup, more work coming  
2125 6371 d 0 h decky /trunk/ experimental support for Objective C
(disabled by default)		  
2104 6383 d 9 h decky /trunk/kernel/generic/src/lib/ more fine order of magnitude display  
2089 6385 d 6 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes		  
2071 6395 d 23 h jermar /trunk/ (c) versus (C)  
2063 6410 d 2 h jermar /trunk/kernel/generic/src/lib/ Call big endian byte swap function instead of little endian.  
2062 6410 d 3 h jermar /trunk/kernel/generic/src/lib/ switch statement coding style fixes.  
2050 6425 d 10 h decky /trunk/kernel/ benchmarking with statistics (initial)  
2015 6435 d 0 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.		  
2005 6444 d 4 h decky /trunk/ update rd  
2002 6444 d 6 h decky /trunk/kernel/generic/ rd work  
2000 6446 d 9 h decky /trunk/kernel/ move files to more proper locations  
1896 6512 d 22 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 6586 d 1 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1780 6593 d 3 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1757 6607 d 7 h jermar /kernel/trunk/ Cleanup of comments.  
1708 6611 d 9 h jermar /kernel/trunk/ Fix some broken doxygen comments.  
1702 6614 d 5 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1612 6621 d 4 h jermar /kernel/trunk/generic/src/lib/ Generic version of memcpy that is resistent towards unaligned memory accesses.  
1425 6631 d 0 h jermar /kernel/trunk/generic/ Make address space backend data a union.  
1424 6631 d 2 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 6631 d 6 h jermar /kernel/trunk/ Update page fault handlers to distinguish between different access modes that had caused the page fault.  
1411 6634 d 3 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 6634 d 21 h jermar /kernel/trunk/generic/ Some shared memory stuff (not completed).
Support for address space area backends.
Add ELF and anonymous memory backends.		  
1264 6657 d 7 h jermar /kernel/trunk/generic/ Improve Doxygen-comments.  
1248 6661 d 3 h jermar /kernel/trunk/ Add some @file doxygen comments and improve already existing comments.  
1239 6662 d 2 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 6672 d 7 h cejka /kernel/trunk/ Printf ported back from uspace to kernel.
Printf calls changed to match new conventions.		  
1100 6698 d 23 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 6702 d 10 h jermar /kernel/trunk/ More checks for address space area conflicts.  
1048 6703 d 5 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 6703 d 20 h jermar /kernel/trunk/generic/ Support only anonymous address space areas.  
973 6705 d 8 h palkovsky /kernel/trunk/generic/ Added simpler userspace starting.  
963 6705 d 22 h jermar /kernel/trunk/generic/src/lib/ Fix bug in loading ELF segment.  
952 6706 d 4 h jermar /kernel/trunk/ Support for loading segments containing .bss section.
