1967 6421 d 4 h jermar /tags/0.2.0.3/ Tagging release 0.2.0.3  
1823 6508 d 10 h jermar /trunk/kernel/arch/sparc64/ sparc64 work.
Dump take_over_tlb_and_tt() and add its assembly language replacement.
 
1822 6508 d 14 h jermar /trunk/ sparc64 work.
1. Formatting fixes.
2. When writing to DMMU ASI's, simple membar() can be used in place of flush().
3. Substantial changes in the way the TLB is taken over.
4. Remove unneeded functions.

This is the first revision that also runs on a real world Ultra 5 with UltraSPARC IIi
processor.

Note that 3. needs further work as the current implementation depends on the fact
that the compiler will use registers for local variables in take_over_tlb_and_tt().
Rewrite of that function into assembly is to follow.
 
1802 6524 d 1 h decky /trunk/ cleanup and unify the build system  
1793 6526 d 14 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 6527 d 4 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 6527 d 8 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 6527 d 11 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 6529 d 7 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1784 6530 d 5 h jermar /kernel/trunk/ Sync OpenFirmware functionality with boot.
Random cleanup.
 
1780 6536 d 9 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1777 6536 d 11 h jermar /kernel/trunk/ Make sparc64 kernel assume it is loaded by our loader.  
1770 6537 d 10 h jermar /kernel/trunk/arch/sparc64/src/mm/ Fix sparc64 to compile again.  
1769 6539 d 4 h jermar /kernel/trunk/arch/ Change cache_error exception to take istate * as a parameter.
Make cache_error() print epc in the panic message.
Do not rely on the compiler to generate 'nop' after 'beq' in atomic_add()
and put it there explicitly.
Indentation fixes and cosmetic changes.
 
1760 6547 d 10 h palkovsky /kernel/trunk/ Changed interface of frame_alloc/free to use address of frame instead of the pfn.
This makes it impossible to use >4GB of memory on 32-bit machines, but who cares...
 
1735 6552 d 15 h decky /kernel/trunk/ make kernel prints case consistent  
1731 6553 d 1 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 6554 d 15 h jermar /kernel/trunk/ Fix some broken doxygen comments.  
1705 6556 d 14 h cejka /kernel/trunk/ Added file with modules definitions and descriptions.
We are able to change modules order and their description in one place.
 
1704 6556 d 18 h cejka /kernel/trunk/ Fixed first letter size of subgroup name in Others.  
1703 6556 d 18 h jermar /kernel/trunk/arch/ Put sparc64 interrupt stuff under the Interrupt group in Doxygen-generated documentation.  
1702 6557 d 11 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1597 6564 d 17 h palkovsky /kernel/trunk/ Added possibility to interrupt task at exit from interrupt routine.  
1595 6564 d 18 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 6565 d 8 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 6568 d 11 h palkovsky /kernel/trunk/arch/ Remove __address from include file included by uspace  
1474 6570 d 4 h palkovsky /kernel/trunk/ Added syscall that lets kernel regain access to keyboard.  
1410 6577 d 12 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.
 
1382 6581 d 5 h decky /kernel/trunk/ make hardware memory mapping more generic  
1377 6582 d 12 h jermar /kernel/trunk/arch/sparc64/include/drivers/ Remove unneeded macro.  
1376 6582 d 13 h jermar /kernel/trunk/ Change the way the framebuffer is mapped so that sparc64 is usable again.  
1288 6596 d 14 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.
 
1280 6599 d 6 h jermar /kernel/trunk/arch/ Get rid off obsolete ddi_int_control_arch() on ia64, sparc64 and ppc32.  
1265 6600 d 13 h jermar /kernel/trunk/arch/ Add dummy IRQ_COUNT and irq_ipc_bind_arch() to ia64, ppc32 and sparc64 so that they compile again.  
1227 6608 d 10 h jermar /kernel/trunk/ Reorganize syscall names to better correspond to kernel architecture.
Add dummy placeholders for SYS_AS_AREA_SHARE_APPROVE and
SYS_AS_AREA_SHARE_PERFORM syscalls.
 
1223 6608 d 13 h jermar /kernel/trunk/ Make ia64 and sparc64 compile again.
Fix ia64 to set up inits in arch_pre_main().
 
1221 6609 d 3 h decky /kernel/trunk/ printf-related and other code cleanup  
1196 6615 d 13 h cejka /kernel/trunk/ Printf ported back from uspace to kernel.

1191 6617 d 17 h jermar /kernel/trunk/ Kernel support for SYS_ENABLE_IOSPACE.
amd64 and ia32 provide dummy implementation thereof.
 
1187 6618 d 8 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.
