2054 6376 d 6 h jermar /trunk/kernel/ Fix important comment in kernel/arch/sparc64/src/proc/scheduler.c.

Improve framebuffer code.

Formatting and indentation fixes.		  
2049 6379 d 16 h jermar /trunk/kernel/arch/sparc64/src/ More formatting and indentation changes.  
2048 6380 d 9 h jermar /trunk/ Formatting and indentation changes.  
2047 6382 d 7 h jermar /trunk/kernel/arch/sparc64/include/ Convert sparc64 critical section barriers to RMO memory model.
More portable, no confusion from documentation.		  
2046 6382 d 9 h jermar /trunk/kernel/arch/sparc64/include/ Another comment fix.  
2045 6382 d 9 h jermar /trunk/kernel/arch/sparc64/include/ Fix comment.  
2044 6382 d 10 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 6382 d 10 h jermar /trunk/kernel/arch/sparc64/src/ Make the sparc64 kernel compile again.  
2038 6383 d 6 h jermar /trunk/kernel/arch/sparc64/ Remove old stuff.  
2037 6383 d 6 h jermar /trunk/kernel/arch/sparc64/include/ Backout change from revision 2034.
sparc64 is not yet ready for get_cycle().		  
2034 6383 d 14 h jermar /trunk/kernel/arch/sparc64/include/ get_cycle() for sparc64.  
2033 6383 d 14 h decky /trunk/kernel/arch/ppc32/include/ get_cycle() for PPC32  
2025 6385 d 5 h jermar /trunk/ Coding style fixes.  
2023 6385 d 9 h decky /trunk/kernel/arch/ add dummy cycle.h  
2018 6385 d 11 h decky /trunk/kernel/ rename rdtsc() to get_cycle()  
2017 6385 d 14 h decky /trunk/kernel/arch/ia32xen/ update for Xen  
2016 6385 d 15 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 6387 d 8 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 6389 d 10 h decky /trunk/ version bump to Xen 3.0.3 (not fully operational yet)  
2010 6392 d 7 h jermar /trunk/kernel/arch/sparc64/src/mm/ Fix comment.  
2009 6392 d 7 h jermar /trunk/kernel/ Initial support for handling illegal virtual aliases on sparc64.  
2008 6394 d 8 h jermar /trunk/kernel/arch/sparc64/ Add dcache_flush() function that flushes D-Cache on sparc64.  
2007 6395 d 6 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 6396 d 13 h decky /trunk/kernel/arch/ cleanup endian conversion macros  
2001 6398 d 5 h jermar /trunk/kernel/ Indentation and comment fixes.  
1996 6404 d 10 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 6404 d 15 h decky /trunk/ Add BGR 0888 visual for Ultra 60  
1993 6404 d 16 h decky /trunk/ make framebuffer code more generic  
1988 6406 d 6 h jermar /trunk/kernel/arch/sparc64/src/mm/ Update comment and move initialization code away from application processor codepath.  
1987 6406 d 9 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 6406 d 13 h decky /trunk/kernel/arch/sparc64/src/drivers/ The FFB framebuffer looks more like 32b  
1984 6407 d 8 h jermar /trunk/kernel/arch/sparc64/ sparc64 work:
- untested support for Psycho PCI controller		  
1983 6408 d 12 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 6408 d 16 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 6408 d 17 h jermar /trunk/kernel/arch/mips32/include/mm/ mips32 mm has not been under construction for while now  
1978 6409 d 8 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 6410 d 5 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 6415 d 14 h jermar /trunk/kernel/arch/sparc64/ sparc64 context does not have to include the CLEANWIN register.  
1975 6419 d 6 h jermar /trunk/kernel/arch/sparc64/src/ Typo.  
1970 6428 d 16 h decky /trunk/kernel/arch/ia32/src/smp/ use new IRQ scheme in l_apic_timer_interrupt()
