2307 6278 d 15 h hudecek /branches/rcu/ Updated branch to latest trunk revision  
2296 6285 d 12 h hudecek /branches/rcu/kernel/ Tasklets working, some forgotten backporting from trunk  
2292 6287 d 3 h hudecek /branches/rcu/ updated to latest trunk revision, minor tweaks in tasklet.c  
2131 6321 d 19 h decky /branches/ add development branches  
2107 6370 d 15 h jermar /trunk/ When clock() is called by an external interrupt dispatched by the IRQ dispatcher,
no spinlock can be held or the kernel will not be preemptive. This fixes Ticket #24.

Formating and indentation fixes.		  
2091 6376 d 19 h jermar /trunk/kernel/arch/sparc64/src/ Fix creating the kkbdpoll() kernel thread on sparc64 SMP machines.
This fixes Ticket #19.		  
2089 6376 d 23 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes		  
2082 6382 d 23 h decky /trunk/ __asm__ __volatile__ -> asm volatile  
2078 6383 d 20 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 6386 d 0 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 6387 d 16 h jermar /trunk/ (c) versus (C)  
2067 6397 d 22 h jermar /trunk/kernel/ More formatting changes.  
2058 6414 d 1 h jermar /trunk/kernel/arch/sparc64/src/ Improve comments.  
2055 6415 d 4 h jermar /trunk/kernel/arch/sparc64/src/ sparc64 work:
- No need to lock kernel stack and userspace window buffer into DTLB.		  
2054 6415 d 14 h jermar /trunk/kernel/ Fix important comment in kernel/arch/sparc64/src/proc/scheduler.c.

Improve framebuffer code.

Formatting and indentation fixes.		  
2049 6419 d 0 h jermar /trunk/kernel/arch/sparc64/src/ More formatting and indentation changes.  
2048 6419 d 17 h jermar /trunk/ Formatting and indentation changes.  
2044 6421 d 18 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 6421 d 18 h jermar /trunk/kernel/arch/sparc64/src/ Make the sparc64 kernel compile again.  
2038 6422 d 14 h jermar /trunk/kernel/arch/sparc64/ Remove old stuff.  
2016 6424 d 23 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 6426 d 16 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 6431 d 15 h jermar /trunk/kernel/arch/sparc64/src/mm/ Fix comment.  
2009 6431 d 15 h jermar /trunk/kernel/ Initial support for handling illegal virtual aliases on sparc64.  
2008 6433 d 16 h jermar /trunk/kernel/arch/sparc64/ Add dcache_flush() function that flushes D-Cache on sparc64.  
2001 6437 d 13 h jermar /trunk/kernel/ Indentation and comment fixes.  
1996 6443 d 18 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 6443 d 23 h decky /trunk/ Add BGR 0888 visual for Ultra 60  
1993 6444 d 0 h decky /trunk/ make framebuffer code more generic  
1988 6445 d 14 h jermar /trunk/kernel/arch/sparc64/src/mm/ Update comment and move initialization code away from application processor codepath.  
1987 6445 d 17 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 6445 d 20 h decky /trunk/kernel/arch/sparc64/src/drivers/ The FFB framebuffer looks more like 32b  
1984 6446 d 16 h jermar /trunk/kernel/arch/sparc64/ sparc64 work:
- untested support for Psycho PCI controller		  
1983 6447 d 20 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 6448 d 0 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 6448 d 16 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 6449 d 13 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 6454 d 22 h jermar /trunk/kernel/arch/sparc64/ sparc64 context does not have to include the CLEANWIN register.  
1975 6458 d 14 h jermar /trunk/kernel/arch/sparc64/src/ Typo.  
1960 6469 d 16 h jermar /trunk/kernel/arch/sparc64/src/mm/ Fix the following bug:

Ticket #3 data_access_exception after killing task on sparc64
