4581 5659 d 11 h mejdrech /branches/network/ Net: synchronized with trunk rev.4580  
4153 5760 d 10 h mejdrech /branches/network/ Networking: merged with trunk changes  
3386 5956 d 13 h decky /branches/network/ add new network branch (copy of current trunk)  
2439 6417 d 8 h decky /trunk/kernel/arch/ia32/src/ fix ICC compilation  
2218 6471 d 6 h decky /trunk/kernel/ support the possibility to send EOI or Interrupt Acknowledgement
prior to processing the interrupt
(this is essential on some architectures to prevent preemption deadlock)
 
2107 6534 d 8 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.
 
2071 6551 d 9 h jermar /trunk/ (c) versus (C)  
1956 6633 d 18 h decky /trunk/kernel/ ia32: adopt new IRQ interface, mouse not tested yet  
1939 6642 d 13 h decky /trunk/ ia32: fix compilation, keyboard not checked yet  
1937 6642 d 20 h decky /trunk/kernel/arch/ remove orphaned functions  
1787 6741 d 11 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1780 6748 d 12 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1735 6764 d 19 h decky /kernel/trunk/ make kernel prints case consistent  
1724 6765 d 22 h palkovsky /kernel/trunk/arch/ Let mouse work on amd64 too.  
1705 6768 d 18 h cejka /kernel/trunk/ Added file with modules definitions and descriptions.
We are able to change modules order and their description in one place.
 
1703 6768 d 22 h jermar /kernel/trunk/arch/ Put sparc64 interrupt stuff under the Interrupt group in Doxygen-generated documentation.  
1702 6769 d 15 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1690 6772 d 9 h palkovsky /kernel/trunk/ Yet another fix with framebuffer.  
1595 6776 d 22 h palkovsky /kernel/trunk/ Added kernel circular buffer klog.
Added automatic killing of tasks raising inappropriate exceptions.
TODO: Fix vsnprintf return value(and behaviour according to specs) and remove workaround in klog.
 
1477 6782 d 0 h decky /kernel/trunk/arch/ cleanup  
1411 6789 d 13 h jermar /kernel/trunk/ Modify the hierarchy of page fault handlers to pass access mode that caused the fault.
Architectures are required to pass either PF_ACCESS_READ, PF_ACCESS_WRITE or PF_ACCESS_EXEC
to as_page_fault(), depending on the cause of the fault.
 
1288 6808 d 18 h jermar /kernel/trunk/ Complete implementation of copy_from_uspace() and copy_to_uspace()
for amd64 and ia32. Other architectures still compile and run,
but need to implement their own assembly-only memcpy(), memcpy_from_uspace(),
memcpy_to_uspace() and their failover parts. For these architectures
only dummy implementations are provided.
 
1258 6814 d 7 h palkovsky /kernel/trunk/ Added support for IRQ notifiactions.
- seems to work correctly on ia32, amd64
- the mips kbd probably lowers interrupts when the char is read from
the port, we will have to find a way how to deal with it.
 
1256 6814 d 15 h jermar /kernel/trunk/arch/ Improve SYS_IOSPACE_ENABLE support.
The general protection fault handler now contains
code to service early I/O Permission bitmap faults.
 
1221 6821 d 7 h decky /kernel/trunk/ printf-related and other code cleanup  
1196 6827 d 16 h cejka /kernel/trunk/ Printf ported back from uspace to kernel.
Printf calls changed to match new conventions.
 
1100 6854 d 9 h palkovsky /kernel/trunk/ Cleanup of spinlocks, now compiles both ia32 and amd64 with
and without DEBUG_SPINLOCKS. Made spinlocks inline.
Moved syscall_handler to generic (it was identical for ia32,amd64 & mips32).
Made slightly faster syscall for ia32.
Made better interrupt routines for ia32.
Allow not saving non-scratch registers during interrupt on ia32,amd64,mips32.
Aligned interrupt handlers on ia32,amd64, this should prevent problems
with different instruction lengths.
 
1019 6859 d 13 h vana /kernel/trunk/arch/ia32/ ia32 MMX and SSEx support  
1008 6859 d 17 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.
 
959 6861 d 9 h palkovsky /kernel/trunk/ New synchronous ipc.
Widened syscall to support up to 5 parameters.
 
958 6861 d 9 h jermar /kernel/trunk/ Nicer ia32 interrupt handlers and structures holding interrupted context data.
Unify the name holding interrupted context data on all architectures to be istate.
 
955 6861 d 10 h palkovsky /kernel/trunk/ Added kernel IPC functionality.  
825 6893 d 13 h jermar /kernel/trunk/ Remove WAKEUP_IPI stuff.

Make it possible to use PAGE_GLOBAL on ia32, amd64 and mips32.
Make ia32 and amd64 map the kernel using PAGE_GLOBAL.
 
714 6918 d 12 h decky /kernel/trunk/ syscall handler return value
uspace task termination (primitive)
 
712 6918 d 13 h decky /kernel/trunk/ "Hello world" from user space :)  
703 6920 d 17 h jermar /kernel/trunk/ Memory management work.
- vm.* -> as.* (as like address space is, imho, more fitting)
- Don't do TLB shootdown on vm_install(). Some architectures only need to call tlb_invalidate_asid().
- Don't allocate all frames for as_area in as_area_create(), but let them be allocated on-demand by as_page_fault().
- Add high-level page fault handler as_page_fault().
- Add as_area_load_mapping().
 
576 6955 d 5 h palkovsky /kernel/trunk/ Changed ia32 & amd64 to use exc_register instead of trap_register.

Fixed dependency list building. I hope you all have 'makedepend' installed,
if you don't it's time to install it, as CC -M builds the dependency
list without directory names..and it just does not work.
 
534 6960 d 10 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel again.  
532 6960 d 10 h jermar / Revert renaming of HelenOS/SPARTAN to HelenOS/kernel because of important pending patch.  
501 6972 d 14 h jermar / Rename HelenOS/SPARTAN to HelenOS/kernel.
