2307 6359 d 0 h hudecek /branches/rcu/ Updated branch to latest trunk revision  
2296 6365 d 21 h hudecek /branches/rcu/kernel/ Tasklets working, some forgotten backporting from trunk  
2292 6367 d 12 h hudecek /branches/rcu/ updated to latest trunk revision, minor tweaks in tasklet.c  
2131 6402 d 4 h decky /branches/ add development branches  
2089 6457 d 8 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes
 
2078 6464 d 5 h jermar /trunk/kernel/arch/sparc64/src/ When invalidating entire TLBs on sparc64, make sure to also invalidate any (locked) global entries.
This fixes Ticket #21.
Fix a comment in start.S stating that the kernel installs a global entry for itself. All entries installed by the kernel
are local to some memory context.
 
2076 6466 d 9 h jermar /trunk/kernel/ Beat the implicit illegal virtual alias created by reusing userspace frames.
In the anonymous and ELF backends, if the architecture has virtually indexed D-cache,
selectively flush cachelines belonging to the frame being freed.
This fixes Ticket #20.
 
2071 6468 d 1 h jermar /trunk/ (c) versus (C)  
2048 6500 d 2 h jermar /trunk/ Formatting and indentation changes.  
2016 6505 d 8 h jermar /trunk/kernel/arch/sparc64/src/mm/ The D-cache line size is actually 32 bytes on UltraSPARC II, IIi (and also IIe).  
2015 6507 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.
 
2010 6512 d 0 h jermar /trunk/kernel/arch/sparc64/src/mm/ Fix comment.  
2009 6512 d 0 h jermar /trunk/kernel/ Initial support for handling illegal virtual aliases on sparc64.  
2008 6514 d 1 h jermar /trunk/kernel/arch/sparc64/ Add dcache_flush() function that flushes D-Cache on sparc64.  
2001 6517 d 22 h jermar /trunk/kernel/ Indentation and comment fixes.  
1996 6524 d 3 h jermar /trunk/kernel/ Add option to compile the sparc64 kernel without the TTE_CV bit support.
The bit is not used by default now.
Enabling it may theoretically lead to physical memory inconsistencies until code that
mitigates the problem is written.
 
1988 6525 d 23 h jermar /trunk/kernel/arch/sparc64/src/mm/ Update comment and move initialization code away from application processor codepath.  
1987 6526 d 2 h jermar /trunk/kernel/arch/sparc64/src/ Take the possible difference between kernel and physical address into account in TSB and userspace window buffer
allocation and deallocation code.
 
1983 6528 d 5 h jermar /trunk/kernel/arch/sparc64/src/mm/ sparc64 work:
- fix computation of the frame allocator configuration frame
- mark the first physical frame unavailable, no matter what is its address

Because of that, we can now boot past the frame_arch_init() on the Ultra 60 now.
 
1982 6528 d 9 h jermar /trunk/ Modify the sparc64 startup code to not cause MMU traps before it takes over the TLB and
the trap table. Fix several PA2KA and KA2PA omittions or errors. Fix configuration to pass
the DEFS variable along.
