2054 6458 d 0 h jermar /trunk/kernel/ Fix important comment in kernel/arch/sparc64/src/proc/scheduler.c.

Improve framebuffer code.

Formatting and indentation fixes.		  
2049 6461 d 10 h jermar /trunk/kernel/arch/sparc64/src/ More formatting and indentation changes.  
2048 6462 d 3 h jermar /trunk/ Formatting and indentation changes.  
2047 6464 d 1 h jermar /trunk/kernel/arch/sparc64/include/ Convert sparc64 critical section barriers to RMO memory model.
More portable, no confusion from documentation.		  
2046 6464 d 3 h jermar /trunk/kernel/arch/sparc64/include/ Another comment fix.  
2045 6464 d 3 h jermar /trunk/kernel/arch/sparc64/include/ Fix comment.  
2044 6464 d 4 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 6464 d 4 h jermar /trunk/kernel/arch/sparc64/src/ Make the sparc64 kernel compile again.  
2038 6465 d 0 h jermar /trunk/kernel/arch/sparc64/ Remove old stuff.  
2037 6465 d 0 h jermar /trunk/kernel/arch/sparc64/include/ Backout change from revision 2034.
sparc64 is not yet ready for get_cycle().		  
2034 6465 d 8 h jermar /trunk/kernel/arch/sparc64/include/ get_cycle() for sparc64.  
2033 6465 d 8 h decky /trunk/kernel/arch/ppc32/include/ get_cycle() for PPC32  
2025 6466 d 23 h jermar /trunk/ Coding style fixes.  
2023 6467 d 3 h decky /trunk/kernel/arch/ add dummy cycle.h  
2018 6467 d 5 h decky /trunk/kernel/ rename rdtsc() to get_cycle()  
2017 6467 d 8 h decky /trunk/kernel/arch/ia32xen/ update for Xen  
2016 6467 d 9 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 6469 d 2 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.		  
2014 6471 d 4 h decky /trunk/ version bump to Xen 3.0.3 (not fully operational yet)  
2010 6474 d 1 h jermar /trunk/kernel/arch/sparc64/src/mm/ Fix comment.  
2009 6474 d 1 h jermar /trunk/kernel/ Initial support for handling illegal virtual aliases on sparc64.  
2008 6476 d 2 h jermar /trunk/kernel/arch/sparc64/ Add dcache_flush() function that flushes D-Cache on sparc64.  
2007 6477 d 0 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 6478 d 7 h decky /trunk/kernel/arch/ cleanup endian conversion macros  
2001 6479 d 23 h jermar /trunk/kernel/ Indentation and comment fixes.  
1996 6486 d 4 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 6486 d 9 h decky /trunk/ Add BGR 0888 visual for Ultra 60  
1993 6486 d 10 h decky /trunk/ make framebuffer code more generic  
1988 6488 d 0 h jermar /trunk/kernel/arch/sparc64/src/mm/ Update comment and move initialization code away from application processor codepath.  
1987 6488 d 3 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 6488 d 7 h decky /trunk/kernel/arch/sparc64/src/drivers/ The FFB framebuffer looks more like 32b  
1984 6489 d 2 h jermar /trunk/kernel/arch/sparc64/ sparc64 work:
- untested support for Psycho PCI controller		  
1983 6490 d 6 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 6490 d 10 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.		  
1980 6490 d 11 h jermar /trunk/kernel/arch/mips32/include/mm/ mips32 mm has not been under construction for while now  
1978 6491 d 2 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.		  
1977 6491 d 23 h jermar /trunk/ Fix bad indentation in ofw.c

sparc64 work:
o Fix copyright in main.c
o Move code from unused parts of the trap table.		  
1976 6497 d 8 h jermar /trunk/kernel/arch/sparc64/ sparc64 context does not have to include the CLEANWIN register.  
1975 6501 d 1 h jermar /trunk/kernel/arch/sparc64/src/ Typo.  
1970 6510 d 10 h decky /trunk/kernel/arch/ia32/src/smp/ use new IRQ scheme in l_apic_timer_interrupt()
