1851 6477 d 12 h jermar /trunk/kernel/ sparc64 work.
Define the istate structure.
Move the identity-mapping handler to assembly.
Make the preemptible handler more general so that TL=1 MMU exceptions can make use of it.

Little bit of formatting and indentation.
 
1839 6493 d 9 h decky /trunk/kernel/generic/ finish security context isolation  
1833 6497 d 1 h decky /trunk/kernel/ more sophisticated initial stack handling  
1826 6497 d 8 h decky /trunk/kernel/generic/src/main/ some debugging output  
1822 6497 d 14 h jermar /trunk/ sparc64 work.
1. Formatting fixes.
2. When writing to DMMU ASI's, simple membar() can be used in place of flush().
3. Substantial changes in the way the TLB is taken over.
4. Remove unneeded functions.

This is the first revision that also runs on a real world Ultra 5 with UltraSPARC IIi
processor.

Note that 3. needs further work as the current implementation depends on the fact
that the compiler will use registers for local variables in take_over_tlb_and_tt().
Rewrite of that function into assembly is to follow.
 
1820 6501 d 2 h decky /trunk/kernel/generic/ initial security context support  
1819 6501 d 2 h decky /trunk/kernel/generic/include/ formatting changes  
1812 6505 d 11 h decky /trunk/kernel/ move macro and cleanup  
1793 6515 d 14 h jermar /trunk/kernel/ Change hw_map() on sparc64 to use virtual addresses that are
beyond the end of physical memory. It is beneficial in two
ways: first, physical memory is no longer being wasted by
otherwise necessary calls to frame_alloc() and, second,
virtual addresses for devices are now correctly allocated
and do not overlap with the 4M TLB-locked mapping for
kernel text and data.
 
1790 6516 d 8 h jermar /trunk/ Remove OpenFirmware calls from kernel/ entirely.

Switch the sparc64 port to use bootinfo.

Copy memcpy from boot/ to sparc64 kernel/ and
adjust it for memcpy_from/to_uspace.
 
1787 6518 d 7 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1780 6525 d 8 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1767 6533 d 15 h palkovsky /kernel/trunk/ Remove unneeded FRAME_PANIC.
Fix some things broken by last commit.
 
1766 6533 d 15 h palkovsky /kernel/trunk/ Changed frame_alloc call, cleaned a lot of stuff, fixed some not-perfectly-correct error handling.  
1760 6536 d 9 h palkovsky /kernel/trunk/ Changed interface of frame_alloc/free to use address of frame instead of the pfn.
This makes it impossible to use >4GB of memory on 32-bit machines, but who cares...
 
1757 6539 d 13 h jermar /kernel/trunk/ Cleanup of comments.  
1735 6541 d 15 h decky /kernel/trunk/ make kernel prints case consistent  
1731 6542 d 1 h jermar /kernel/trunk/ Updates in Doxygen-style comments.
Make architecture specific modules appear conditionally in the documentation.
Add time management module.
Improve names of other modules and sort module order
to be more like in the design documentation.
 
1729 6542 d 1 h decky /kernel/trunk/generic/src/main/ coding style changes  
1712 6543 d 6 h palkovsky /kernel/trunk/generic/ Send to uspace notification about end of kconsole mode.
