4638 5590 d 7 h rimsky /branches/sparc/kernel/ SMP on Niagara made working: debugged the problem with the 'non-deterministic' symptoms, implemented the IPI mechanism.  
3862 5748 d 0 h rimsky /branches/sparc/kernel/ Changed the structure of header files, which have sun4u and sun4v versions. Implemented some sun4v TSB functions.  
3770 5781 d 1 h rimsky /branches/sparc/ Working on Niagara port - TLB initialization, MMU fault status area initialization, hypercall enhancement, modified tick.c so that the (hyperprivileged) TICK register does not have to be accessed. Now the initialization phase proceeds, but some parts of it are omitted for now (e.g. CPU initialization).  
3665 5811 d 23 h rimsky /branches/sparc/ Merged latest trunk changes into the sparc brach.  
3593 5826 d 23 h rimsky /branches/sparc/ Merged latest trunk changes into sparc branch.  
3343 5917 d 5 h decky /branches/sparc/ add sparc branch  
2745 6091 d 11 h decky /trunk/ code cleanup (mostly signed/unsigned)
allow extra compiler warnings
 
2133 6429 d 3 h jermar /trunk/kernel/generic/src/mm/ Coding style and indentation fixes.  
2089 6486 d 9 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes
 
2071 6497 d 2 h jermar /trunk/ (c) versus (C)  
1904 6608 d 7 h jermar /trunk/kernel/ IPI/cross-call support for sparc64.
SMP on sparc64 is now fully supported.
 
1787 6687 d 4 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1780 6694 d 5 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1757 6708 d 10 h jermar /kernel/trunk/ Cleanup of comments.  
1702 6715 d 8 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1297 6752 d 7 h jermar /kernel/trunk/ Add SYS_CAP_GRANT and SYS_CAP_REVOKE syscalls.
Move SYS_PREEMPT_CONTROL to ddi.c.
Add some comments and fix some small issues.
 
1248 6762 d 5 h jermar /kernel/trunk/ Add some @file doxygen comments and improve already existing comments.  
1104 6798 d 5 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.
 
1008 6805 d 10 h jermar /kernel/trunk/ Fix bug in ia32 interrupt handlers.
Handlers for interrupts greater than 31 wrapped the shift around and thus failed to correctly identify
the need to emulate error word.
 
1002 6805 d 22 h jermar /kernel/trunk/generic/ More lightweighed TLB shootdown implementation.  
740 6855 d 8 h jermar /kernel/trunk/ ia64 ASID management code (not tested).  
727 6860 d 0 h jermar /kernel/trunk/ New ASID management subsystem (initial work, more is required).
Some TLB invalidation changes.
 
623 6895 d 12 h jermar /kernel/trunk/ Add SPINLOCK_DECLARE and SPINLOCK_INITIALIZE macros.
SPINLOCK_DECLARE is to be used instead of direct spinlock_t declarations
in dynamically allocated structures on which spinlock_initialize() is called after
their creation.
SPINLOCK_INITIALIZE is to be used instead of direct spinlock_t declarations
of global spinlocks. It declares and initializes the spinlock.
Moreover, both macros are empty on UP so that -Wall warnings about unused structures
get supressed.
 
594 6900 d 3 h jermar /kernel/trunk/ ptlb command (currently usable on mips32 only).  
569 6902 d 0 h jermar /kernel/trunk/ sparc64 work.
Implement functions for reading IMMU and DMMU TLBs.
 
552 6904 d 0 h palkovsky /kernel/trunk/ Named spinlocks  
534 6906 d 3 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.  
532 6906 d 3 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.  
501 6918 d 7 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel.  
458 6932 d 10 h decky /SPARTAN/trunk/ make configuration variables usage consistent  
430 6939 d 0 h jermar /SPARTAN/trunk/ Move src/ and include/ to generic.  
389 6967 d 11 h jermar /SPARTAN/trunk/ MIPS work.
Fix some name inconsistencies between cp0 functions' declarations and definitions.
Add and implement tlb_init_arch().
Add tlb_modified() exception handler.

Other architectures: add dummy tlb_init_arch().
 
111 7087 d 2 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.
 
32 7127 d 1 h jermar /SPARTAN/trunk/ ACPI detection code.
MP detection code rewrite.
Minor changes.
 
31 7128 d 6 h jermar /SPARTAN/trunk/ Replace the deadlock-prone TLB shootdown algorithm with a deadlock-free implementation.
The implementation is a variant of the CMU TLB consistency algorithm.
Very inefficient implementation of a very inefficient (but correct) algorithm.
 
11 7187 d 23 h jermar /SPARTAN/trunk/ Clean up (ia32 vs. i386).
Header files reorganization.
 
7 7190 d 11 h jermar /SPARTAN/trunk/ New IPI for waking up idle CPU's halted in scheduler.
Added architecture-independent ipi_broadcast().
 
6 7191 d 14 h jermar /SPARTAN/trunk/ shootdown vs. shutdown  
5 7192 d 1 h jermar /SPARTAN/trunk/ TLB shootdown.  
1 7195 d 5 h jermar /SPARTAN/ Initial import
