3862 5566 d 3 h rimsky /branches/sparc/kernel/ Changed the structure of header files, which have sun4u and sun4v versions. Implemented some sun4v TSB functions.  
3742 5606 d 13 h rimsky /branches/sparc/ The sparc branch synchronized with trunk at revision 3722 (trunk@3722).  
3665 5630 d 2 h rimsky /branches/sparc/ Merged latest trunk changes into the sparc brach.  
3343 5735 d 8 h decky /branches/sparc/ add sparc branch  
2745 5909 d 13 h decky /trunk/ code cleanup (mostly signed/unsigned)
allow extra compiler warnings
 
2275 6222 d 6 h decky /trunk/kernel/generic/ add fancy uptime kconsole command  
2141 6246 d 1 h jermar /trunk/ The Ultimate Solution To Illegal Virtual Aliases.
It is better to avoid them completely than to fight them.
Switch the sparc64 port to 16K pages. The TLBs and TSBs
continue to operate with 8K pages only. Page tables and
other generic parts operate with 16K pages.

Because the MMU doesn't support 16K directly, each 16K
page is emulated by a pair of 8K pages. With 16K pages,
illegal aliases cannot be created in 16K D-cache.
 
2071 6315 d 5 h jermar /trunk/ (c) versus (C)  
2015 6354 d 5 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.
 
1787 6505 d 7 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1780 6512 d 8 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1760 6523 d 9 h palkovsky /kernel/trunk/ Changed interface of frame_alloc/free to use address of frame instead of the pfn.
This makes it impossible to use >4GB of memory on 32-bit machines, but who cares...
 
1757 6526 d 13 h jermar /kernel/trunk/ Cleanup of comments.  
1731 6529 d 0 h jermar /kernel/trunk/ Updates in Doxygen-style comments.
Make architecture specific modules appear conditionally in the documentation.
Add time management module.
Improve names of other modules and sort module order
to be more like in the design documentation.
 
1705 6532 d 14 h cejka /kernel/trunk/ Added file with modules definitions and descriptions.
We are able to change modules order and their description in one place.
 
1704 6532 d 17 h cejka /kernel/trunk/ Fixed first letter size of subgroup name in Others.  
1702 6533 d 11 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1457 6547 d 3 h jermar /kernel/trunk/generic/src/time/ Project missed_clock_ticks also on thread timeslice and run queue relink counter.  
1438 6549 d 3 h palkovsky /kernel/trunk/generic/ Correct realtime clock communication.  
1434 6549 d 7 h palkovsky /kernel/trunk/ Added 'realtime' clock interface.
Added some asm macros as memory barriers.
Added drift computing for mips platform.
 
1433 6549 d 10 h jermar /kernel/trunk/generic/src/time/ Fix critical bug in timeout processing introduced several hours ago.  
1431 6549 d 14 h jermar /kernel/trunk/generic/ Add missed_clock_ticks to CPU structure so that clock() can detect missed timer interrupts.
Architectures are required to support this in order to make time keeping accurate.
 
1264 6576 d 13 h jermar /kernel/trunk/generic/ Improve Doxygen-comments.  
1196 6591 d 12 h cejka /kernel/trunk/ Printf ported back from uspace to kernel.
Printf calls changed to match new conventions.
 
1104 6616 d 8 h jermar /kernel/trunk/ Define atomic_t only once in atomic.h
Change the encapsulated counter type to long so that it supports negative values as well.
 
788 6661 d 7 h jermar /kernel/trunk/ Move list and fifo data types to adt/.  
615 6715 d 14 h palkovsky /kernel/trunk/ Cleanups to make it compile with -Wall. Did not catch everything yet.  
534 6724 d 5 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.  
532 6724 d 6 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.  
501 6736 d 10 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel.  
430 6757 d 3 h jermar /SPARTAN/trunk/ Move src/ and include/ to generic.  
413 6772 d 2 h jermar /SPARTAN/trunk/ Rename cpu_priority_{high|low|restore|read} functions to interrupts_{disable|enable|restore|read}.
Rename pri_t to ipl_t (Interrupt Priority Level).
Rename thread_t::pri to thread_t::priority.
 
411 6773 d 5 h jermar /SPARTAN/trunk/ Doxygen comments.  
391 6785 d 3 h jermar /SPARTAN/trunk/ mips32 memory management work.
TLB Refill Exception implemented (passed basic testing).
Remove bit g from struct entry_hi.
Add generic find_mapping().
Add asid to vm_t type, define asid_t to hide architecture specific differences.
Implement ASID allocation for mips32, dummy for other architectures.
Add THE->vm (a.k.a. VM).
Add vm_install_arch().
Move pte_t definition to arch/types.h on each architecture.
Fix PTL manipulating functions on mips32 to shift pfn by 12 instead of by 14.
Fix tlb_init_arch() to initialize all entries.

Other.
Remove unnecessary header files from arch.h
Add missing headers here and there.
Remove two unnecessary ld flags from mips32 makefile.
 
221 6818 d 16 h jermar /SPARTAN/trunk/ Preemption work.
Define PREEMPTION_DISABLED macro.
This macro determines the level of preemptivity (0 = preemption enabled, THE->preemption_disabled = no preemption inside spinlock, 1 = preemption disabled).
Reformulate preemption code in clock.c to consider PREEMPTION_DISABLED.
 
125 6866 d 3 h jermar /SPARTAN/trunk/ Huge indentation fix.  
111 6905 d 5 h palkovsky /SPARTAN/trunk/ Code cleanup in scheduler.c thread.c - removed unnecessary spinlock.
atomic_inc, atomic_dec moved to arch/atomic.h instead of arch/smp/atomic.h,
advisable to use even in non-smp mode.
Fixed atomic_inc, atomic_dec in mips architecture.
 
107 6908 d 10 h decky /SPARTAN/trunk/src/ doxygen-style comments
cleanups
 
15 6963 d 7 h jermar /SPARTAN/trunk/ Introduce macros CPU, THREAD, TASK and use them to replace the->cpu, the->thread, the->task.
Later on, this will make it possible to reference *current* cpu, thread and/or task without the aid from virtual memory.
