2015 6384 d 1 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 6393 d 6 h decky /trunk/ update rd  
2002 6393 d 8 h decky /trunk/kernel/generic/ rd work  
2000 6395 d 11 h decky /trunk/kernel/ move files to more proper locations  
1896 6462 d 0 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 6535 d 3 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1780 6542 d 4 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1757 6556 d 9 h jermar /kernel/trunk/ Cleanup of comments.  
1708 6560 d 10 h jermar /kernel/trunk/ Fix some broken doxygen comments.  
1702 6563 d 7 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1612 6570 d 6 h jermar /kernel/trunk/generic/src/lib/ Generic version of memcpy that is resistent towards unaligned memory accesses.  
1425 6580 d 2 h jermar /kernel/trunk/generic/ Make address space backend data a union.  
1424 6580 d 4 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 6580 d 8 h jermar /kernel/trunk/ Update page fault handlers to distinguish between different access modes that had caused the page fault.  
1411 6583 d 5 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 6583 d 23 h jermar /kernel/trunk/generic/ Some shared memory stuff (not completed).
Support for address space area backends.
Add ELF and anonymous memory backends.		  
1264 6606 d 9 h jermar /kernel/trunk/generic/ Improve Doxygen-comments.  
1248 6610 d 4 h jermar /kernel/trunk/ Add some @file doxygen comments and improve already existing comments.  
1239 6611 d 4 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 6621 d 8 h cejka /kernel/trunk/ Printf ported back from uspace to kernel.
Printf calls changed to match new conventions.
