2131 6434 d 7 h decky /branches/ add development branches  
2107 6483 d 2 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 6489 d 6 h jermar /trunk/kernel/arch/sparc64/src/ Fix creating the kkbdpoll() kernel thread on sparc64 SMP machines.
This fixes Ticket #19.		  
2089 6489 d 10 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes		  
2082 6495 d 10 h decky /trunk/ __asm__ __volatile__ -> asm volatile  
2078 6496 d 7 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 6498 d 11 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 6500 d 3 h jermar /trunk/ (c) versus (C)  
2067 6510 d 9 h jermar /trunk/kernel/ More formatting changes.  
2058 6526 d 12 h jermar /trunk/kernel/arch/sparc64/src/ Improve comments.  
2055 6527 d 16 h jermar /trunk/kernel/arch/sparc64/src/ sparc64 work:
- No need to lock kernel stack and userspace window buffer into DTLB.		  
2054 6528 d 1 h jermar /trunk/kernel/ Fix important comment in kernel/arch/sparc64/src/proc/scheduler.c.

Improve framebuffer code.

Formatting and indentation fixes.		  
2049 6531 d 11 h jermar /trunk/kernel/arch/sparc64/src/ More formatting and indentation changes.  
2048 6532 d 5 h jermar /trunk/ Formatting and indentation changes.  
2044 6534 d 5 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 6534 d 5 h jermar /trunk/kernel/arch/sparc64/src/ Make the sparc64 kernel compile again.  
2038 6535 d 1 h jermar /trunk/kernel/arch/sparc64/ Remove old stuff.  
2016 6537 d 10 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 6539 d 3 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 6544 d 2 h jermar /trunk/kernel/arch/sparc64/src/mm/ Fix comment.
