2078 6421 d 22 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 6424 d 2 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 6425 d 18 h jermar /trunk/ (c) versus (C)  
2068 6433 d 1 h jermar /trunk/kernel/ Formatting and indentation fixes.  
2067 6436 d 0 h jermar /trunk/kernel/ More formatting changes.  
2065 6439 d 16 h jermar /trunk/kernel/ Coding style fixes and formatting improvements.  
2058 6452 d 3 h jermar /trunk/kernel/arch/sparc64/src/ Improve comments.  
2056 6453 d 6 h jermar /trunk/kernel/arch/sparc64/include/ Fix mismatched byteswapping macros on sparc64.  
2055 6453 d 7 h jermar /trunk/kernel/arch/sparc64/src/ sparc64 work:
- No need to lock kernel stack and userspace window buffer into DTLB.		  
2054 6453 d 17 h jermar /trunk/kernel/ Fix important comment in kernel/arch/sparc64/src/proc/scheduler.c.

Improve framebuffer code.

Formatting and indentation fixes.		  
2049 6457 d 2 h jermar /trunk/kernel/arch/sparc64/src/ More formatting and indentation changes.  
2048 6457 d 20 h jermar /trunk/ Formatting and indentation changes.  
2047 6459 d 17 h jermar /trunk/kernel/arch/sparc64/include/ Convert sparc64 critical section barriers to RMO memory model.
More portable, no confusion from documentation.		  
2046 6459 d 19 h jermar /trunk/kernel/arch/sparc64/include/ Another comment fix.  
2045 6459 d 20 h jermar /trunk/kernel/arch/sparc64/include/ Fix comment.  
2044 6459 d 20 h jermar /trunk/kernel/arch/sparc64/ On sparc64's tick interrupt, adjust the TICK_COMPARE register instead of the TICK
register. The TICK register now increments linearily and can be used by the get_cycle()
function.		  
2043 6459 d 20 h jermar /trunk/kernel/arch/sparc64/src/ Make the sparc64 kernel compile again.  
2038 6460 d 16 h jermar /trunk/kernel/arch/sparc64/ Remove old stuff.  
2037 6460 d 16 h jermar /trunk/kernel/arch/sparc64/include/ Backout change from revision 2034.
sparc64 is not yet ready for get_cycle().		  
2034 6461 d 0 h jermar /trunk/kernel/arch/sparc64/include/ get_cycle() for sparc64.  
2025 6462 d 15 h jermar /trunk/ Coding style fixes.  
2023 6462 d 19 h decky /trunk/kernel/arch/ add dummy cycle.h  
2016 6463 d 1 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 6464 d 18 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 6469 d 17 h jermar /trunk/kernel/arch/sparc64/src/mm/ Fix comment.  
2009 6469 d 17 h jermar /trunk/kernel/ Initial support for handling illegal virtual aliases on sparc64.  
2008 6471 d 18 h jermar /trunk/kernel/arch/sparc64/ Add dcache_flush() function that flushes D-Cache on sparc64.  
2007 6472 d 16 h jermar /trunk/kernel/ Introduce page colors. So far, only sparc64 uses correct page color bits. Other architectures have a dummy define
specifying zero bits for a page color.

There is a new check of page color in as_area_share(). Because of lack of support for this in the userspace, the
check has been #ifef'ed out.		  
2003 6473 d 23 h decky /trunk/kernel/arch/ cleanup endian conversion macros  
2001 6475 d 16 h jermar /trunk/kernel/ Indentation and comment fixes.  
1996 6481 d 20 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.		  
1994 6482 d 1 h decky /trunk/ Add BGR 0888 visual for Ultra 60  
1993 6482 d 2 h decky /trunk/ make framebuffer code more generic  
1988 6483 d 16 h jermar /trunk/kernel/arch/sparc64/src/mm/ Update comment and move initialization code away from application processor codepath.  
1987 6483 d 19 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.		  
1986 6483 d 23 h decky /trunk/kernel/arch/sparc64/src/drivers/ The FFB framebuffer looks more like 32b  
1984 6484 d 19 h jermar /trunk/kernel/arch/sparc64/ sparc64 work:
- untested support for Psycho PCI controller		  
1983 6485 d 22 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 6486 d 2 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.		  
1978 6486 d 18 h jermar /trunk/ sparc64 code to support physical memory that starts on non-zero addresses.
Still needs to be tested on systems with such setup.
