1731 6710 d 22 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 6714 d 12 h cejka /kernel/trunk/ Added file with modules definitions and descriptions.
We are able to change modules order and their description in one place.
 
1702 6715 d 9 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1697 6716 d 3 h palkovsky /kernel/trunk/arch/ Fixed incorrect atomic_postinc/postdec...again...  
1692 6717 d 6 h palkovsky /kernel/trunk/arch/amd64/include/ Fix prein/predec instructions to be the same as on ia32.  
1595 6722 d 16 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.
 
1511 6726 d 8 h palkovsky /kernel/trunk/arch/ Remove __address from include file included by uspace  
1477 6727 d 18 h decky /kernel/trunk/arch/ cleanup  
1473 6728 d 3 h decky /kernel/trunk/ kernel support for text-only framebuffer  
1423 6732 d 10 h jermar /kernel/trunk/ Update page fault handlers to distinguish between different access modes that had caused the page fault.  
1411 6735 d 6 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.
 
1292 6754 d 8 h vana /kernel/trunk/arch/ VESA FB cut unwanted  
1289 6754 d 10 h vana /kernel/trunk/arch/ Amd64 framebuffer  
1288 6754 d 11 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.
 
1256 6760 d 8 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.
 
1251 6761 d 9 h jermar /kernel/trunk/ Fix BITS2BYTES macro to return 0 when passed 0 as argument.
Fix ia32 TSS segment granularity to be 0.
Fix ia32 and amd64 initial TSS limit to be 103.
Little textual changes here and there.
 
1212 6767 d 5 h palkovsky /kernel/trunk/ Added uspace call to enable/disable interrupts.  
1203 6772 d 7 h jermar /kernel/trunk/arch/ Full implementation of amd64 and ia32 SYS_ENABLE_IOSPACE syscall.
Needs testing.
 
1201 6772 d 7 h jermar /kernel/trunk/arch/ Fix amd64 and ia32 management of I/O bitmap in before_task_runs_arch()
by treating the iomap array as a bitmap. Make use of the bitmap type
and functions added in previous commit.
 
1187 6776 d 6 h jermar /kernel/trunk/ Cleanup pm.c and pm.h code on ia32 and amd64.
Add before_task_runs() and before_task_runs_arch() for each architecture.
Add ia32 and amd64 code to ensure I/O Permission Bitmap update.
 
1186 6776 d 7 h jermar /kernel/trunk/arch/ Replace assembly from pm.c with new inline functions defined in asm.h.  
1184 6776 d 9 h jermar /kernel/trunk/ Move arch/thread.h to arch/proc/thread.h on all architectures.
Replace ARCH_THREAD_DATA with new thread_arch_t arch on all architectures.
Similarily, add task_arch_t arch on all architectures.
On amd64 and ia32, grow the TSS segment by 64K + 1B to support IO port
permission bitmap. For the same reason, define per task IO port permission bitmaps
on ia32 and amd64.
 
1121 6797 d 2 h jermar /kernel/trunk/ Small textual changes.  
1112 6797 d 13 h palkovsky /kernel/trunk/ Added basic kernel infrastructure for ThreadLocalStorage(TLS) for
ia32(complete),amd64(complete),mips32(missing emulation of rdhwr instruction).
 
1104 6798 d 6 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.
 
1100 6800 d 3 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.
 
1077 6803 d 10 h palkovsky /kernel/trunk/ Modified debugger to be able to coexist in AS watch mode and SMP.  
1072 6803 d 12 h palkovsky /kernel/trunk/ Added debugger to AMD64.
Added automatic debugging of AS if it is not rewritten with zero.
Did small changes to IPC infrastructure.
 
1070 6803 d 13 h jermar /kernel/trunk/ More checks for address space area conflicts.  
1064 6803 d 23 h palkovsky /kernel/trunk/arch/amd64/ Cleanup of amd64 code.  
1063 6803 d 23 h palkovsky /kernel/trunk/ Add support for more then 2GB of address space for AMD64.  
1051 6804 d 7 h jermar /kernel/trunk/arch/amd64/ Move amd64's ident_page_mapper() and page_fault() to page.h.  
1050 6804 d 7 h palkovsky /kernel/trunk/ Added null console for buffering output when no real output available.
Added identity mapper for AMD64 that allows whole physical memory to be
accessed before paging is initialized.
 
1024 6805 d 4 h jermar /kernel/trunk/ Redefine semantics of unary atomic operations.
Add test to verify that an architecture understands the semantics correctly.
 
1021 6805 d 5 h jermar /kernel/trunk/ Hopefully final version of interrupt handlers for amd64 and ia32.
amd64 has been especially tricky to debug.
Error code detection is now done in compile time.
 
984 6806 d 8 h palkovsky /kernel/trunk/arch/ Fixed invlpg for ia32 & amd64.  
977 6806 d 9 h jermar /kernel/trunk/ Add sys_mremap() syscall.  
967 6806 d 13 h palkovsky /kernel/trunk/ Allowed userspace to include page.h.  
959 6807 d 2 h palkovsky /kernel/trunk/ New synchronous ipc.
Widened syscall to support up to 5 parameters.
 
958 6807 d 3 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.
