1793 6691 d 11 h jermar /trunk/kernel/ Change hw_map() on sparc64 to use virtual addresses that are
beyond the end of physical memory. It is beneficial in two
ways: first, physical memory is no longer being wasted by
otherwise necessary calls to frame_alloc() and, second,
virtual addresses for devices are now correctly allocated
and do not overlap with the 4M TLB-locked mapping for
kernel text and data.
 
1792 6692 d 1 h jermar /trunk/ Move functionality of tlb_arch_init() to take_over_tlb_and_tt().
Call take_over_tlb_and_tt() very early after the kernel starts
executing.
 
1790 6692 d 5 h jermar /trunk/ Remove OpenFirmware calls from kernel/ entirely.

Switch the sparc64 port to use bootinfo.

Copy memcpy from boot/ to sparc64 kernel/ and
adjust it for memcpy_from/to_uspace.
 
1789 6692 d 8 h jermar /trunk/ Fix ofw_memmap() in boot infrastructure.
The cell size is 32-bit and not equal sizeof(ofw_arg_t).
Define architecture dependant #address-cells and #size-cells for cases
the respective properties are missing in the OpenFirmware device tree.
The algorithm now works both for ppc32 and sparc64.

Add memmap_t, screen_t and keyboard_t to sparc64 bootinfo structure.
Be more verbose during sparc64 boot.

Move ALIGN_UP to generic part of boot/.

Change header guards in several places so that they don't contain double underscore.
 
1787 6694 d 4 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1784 6695 d 2 h jermar /kernel/trunk/ Sync OpenFirmware functionality with boot.
Random cleanup.
 
1780 6701 d 5 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1777 6701 d 8 h jermar /kernel/trunk/ Make sparc64 kernel assume it is loaded by our loader.  
1731 6717 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.
 
1708 6719 d 11 h jermar /kernel/trunk/ Fix some broken doxygen comments.  
1705 6721 d 11 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 6721 d 15 h jermar /kernel/trunk/arch/ Put sparc64 interrupt stuff under the Interrupt group in Doxygen-generated documentation.  
1702 6722 d 8 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1597 6729 d 14 h palkovsky /kernel/trunk/ Added possibility to interrupt task at exit from interrupt routine.  
1595 6729 d 15 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.
 
1587 6730 d 5 h jermar /kernel/trunk/ task_destroy() implementation, fixes in as_destroy() and task_kill().
This is the first version of HelenOS that would perform complete cleanup leading from thread to destruction of address space.
 
1511 6733 d 8 h palkovsky /kernel/trunk/arch/ Remove __address from include file included by uspace  
1410 6742 d 9 h jermar /kernel/trunk/arch/sparc64/ Modify sparc64 to choose optimal page size in each invocation of hw_map().
Use hw_map() to map keyboard device memory.
 
1377 6747 d 9 h jermar /kernel/trunk/arch/sparc64/include/drivers/ Remove unneeded macro.  
1288 6761 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.
