4490 5684 d 0 h decky /trunk/kernel/ remove redundant index_t and count_t types (which were always quite ambiguous and not actually needed)  
4137 5761 d 23 h svoboda /trunk/kernel/ Make optionality of symbol information less intrusive per Jakub's request. Also, improve symtab function names and update their semantics.  
4132 5762 d 21 h svoboda /trunk/ Make kernel symbol information optional.  
4016 5776 d 4 h decky /trunk/kernel/ better inline assembler readability using the new symbolic syntax  
3906 5791 d 20 h jermar /trunk/kernel/ IRQ handlers are using one superfluous argument and an unused elipsis.
On the other hand, IRQ claim functions would need to be passed the instance
argument.
 
3890 5792 d 23 h jermar /trunk/ Get rid of CONFIG_DEBUG_ALLREGS.  
3790 5830 d 7 h svoboda /trunk/kernel/ Make newlines in panic messages consistent. Add periods at end of messages so that it is obvious whether they are printed entirely.  
3788 5830 d 20 h svoboda /trunk/kernel/ Unify newlines in fault_if_from_uspace() format strings. (Remove them and print newline automatically). Also start messages with caps.  
2439 6417 d 22 h decky /trunk/kernel/arch/ia32/src/ fix ICC compilation  
2218 6471 d 20 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 22 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 23 h jermar /trunk/ (c) versus (C)  
1956 6634 d 8 h decky /trunk/kernel/ ia32: adopt new IRQ interface, mouse not tested yet  
1939 6643 d 2 h decky /trunk/ ia32: fix compilation, keyboard not checked yet  
1937 6643 d 9 h decky /trunk/kernel/arch/ remove orphaned functions  
1787 6742 d 1 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1780 6749 d 2 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1735 6765 d 8 h decky /kernel/trunk/ make kernel prints case consistent  
1724 6766 d 11 h palkovsky /kernel/trunk/arch/ Let mouse work on amd64 too.  
1705 6769 d 8 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 6769 d 11 h jermar /kernel/trunk/arch/ Put sparc64 interrupt stuff under the Interrupt group in Doxygen-generated documentation.  
1702 6770 d 5 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1690 6772 d 23 h palkovsky /kernel/trunk/ Yet another fix with framebuffer.  
1595 6777 d 12 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 14 h decky /kernel/trunk/arch/ cleanup  
1411 6790 d 2 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 6809 d 7 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 21 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 6815 d 4 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 20 h decky /kernel/trunk/ printf-related and other code cleanup  
1196 6828 d 6 h cejka /kernel/trunk/ Printf ported back from uspace to kernel.
Printf calls changed to match new conventions.
 
1100 6854 d 23 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 6860 d 3 h vana /kernel/trunk/arch/ia32/ ia32 MMX and SSEx support  
1008 6860 d 7 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 22 h palkovsky /kernel/trunk/ New synchronous ipc.
Widened syscall to support up to 5 parameters.
 
958 6861 d 23 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 6862 d 0 h palkovsky /kernel/trunk/ Added kernel IPC functionality.  
825 6894 d 2 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 6919 d 2 h decky /kernel/trunk/ syscall handler return value
uspace task termination (primitive)
 
712 6919 d 2 h decky /kernel/trunk/ "Hello world" from user space :)
