1854 6509 d 1 h jermar /trunk/kernel/ Define architecture-specific thread sub-constructors and sub-destructors on all architectures.
Define the THREAD_FLAG_USPACE which means that the thread runs in user space.
The forementioned changes allow for allocating of user window buffer on sparc64
threads that execute in userspace.

A lot of formatting and indentation fixes.		  
1844 6528 d 17 h jermar /trunk/kernel/ Add an option to compile the sparc64 kernel for Ultra 5 or Enterprise E6500.
Basic keyboard support (polling) based on ns16550 serial port (deployed on Ultra).		  
1842 6528 d 23 h jermar /trunk/kernel/ i8042 and z8530 separated, the tree compiles again.
Now there is some duplicated code in i8042.c and z8530.c,
but that can be eliminated in slower pace.		  
1838 6533 d 20 h jermar /trunk/kernel/ Add scan code map for Sun keyboard.  
1833 6536 d 11 h decky /trunk/kernel/ more sophisticated initial stack handling  
1811 6545 d 0 h decky /trunk/kernel/arch/ unify bootstrapping  
1802 6552 d 11 h decky /trunk/ cleanup and unify the build system  
1787 6557 d 18 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1780 6564 d 19 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1735 6581 d 1 h decky /kernel/trunk/ make kernel prints case consistent  
1731 6581 d 11 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.		  
1724 6582 d 4 h palkovsky /kernel/trunk/arch/ Let mouse work on amd64 too.  
1705 6585 d 1 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 6585 d 4 h cejka /kernel/trunk/ Fixed first letter size of subgroup name in Others.  
1702 6585 d 22 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1697 6586 d 16 h palkovsky /kernel/trunk/arch/ Fixed incorrect atomic_postinc/postdec...again...  
1692 6587 d 19 h palkovsky /kernel/trunk/arch/amd64/include/ Fix prein/predec instructions to be the same as on ia32.  
1641 6592 d 1 h decky /kernel/trunk/arch/ port VESA VBE changes to AMD64  
1595 6593 d 4 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 6593 d 19 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 6596 d 21 h palkovsky /kernel/trunk/arch/ Remove __address from include file included by uspace  
1477 6598 d 7 h decky /kernel/trunk/arch/ cleanup  
1474 6598 d 14 h palkovsky /kernel/trunk/ Added syscall that lets kernel regain access to keyboard.  
1473 6598 d 16 h decky /kernel/trunk/ kernel support for text-only framebuffer  
1423 6602 d 22 h jermar /kernel/trunk/ Update page fault handlers to distinguish between different access modes that had caused the page fault.  
1411 6605 d 19 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.		  
1382 6609 d 15 h decky /kernel/trunk/ make hardware memory mapping more generic  
1303 6620 d 18 h palkovsky /kernel/trunk/arch/ zone_merge_all must be called after frame_init is completed - otherwise
new zone information can be allocated over the not-yet-blacklisted areas.		  
1292 6624 d 21 h vana /kernel/trunk/arch/ VESA FB cut unwanted  
1291 6624 d 22 h vana /kernel/trunk/arch/amd64/src/boot/ VESA detection failure fix on amd64  
1289 6624 d 22 h vana /kernel/trunk/arch/ Amd64 framebuffer  
1288 6625 d 0 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.		  
1281 6627 d 14 h palkovsky /kernel/trunk/ Added means to make a simple action upon interrupt.  
1278 6627 d 18 h palkovsky /kernel/trunk/ Changed interrupt_control to preemption_control.  
1263 6629 d 0 h jermar /kernel/trunk/arch/ When seting TSS limit, take the mandatory extra ending byte with all bits set into account.
Align this group of eight bits on byte boundary.		  
1261 6629 d 23 h jermar /kernel/trunk/arch/ Fixes in amd64 and ia32 ddi_iospace_enable_arch().  
1258 6630 d 14 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.		  
1257 6630 d 21 h jermar /kernel/trunk/arch/ Initialize amd64 and ia32 task iomapver generation counter.  
1256 6630 d 21 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.		  
1255 6631 d 0 h jermar /kernel/trunk/arch/ I/O Permission bitmap fixes. The trailing all-one sequence must be 8 bits long.
Update TSS limit in a proper way.
