1705 6537 d 22 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 6538 d 2 h cejka /kernel/trunk/ Fixed first letter size of subgroup name in Others.  
1702 6538 d 19 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1697 6539 d 14 h palkovsky /kernel/trunk/arch/ Fixed incorrect atomic_postinc/postdec...again...  
1692 6540 d 17 h palkovsky /kernel/trunk/arch/amd64/include/ Fix prein/predec instructions to be the same as on ia32.  
1641 6544 d 23 h decky /kernel/trunk/arch/ port VESA VBE changes to AMD64  
1595 6546 d 2 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 6546 d 16 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 6549 d 19 h palkovsky /kernel/trunk/arch/ Remove __address from include file included by uspace  
1477 6551 d 5 h decky /kernel/trunk/arch/ cleanup  
1474 6551 d 12 h palkovsky /kernel/trunk/ Added syscall that lets kernel regain access to keyboard.  
1473 6551 d 14 h decky /kernel/trunk/ kernel support for text-only framebuffer  
1423 6555 d 20 h jermar /kernel/trunk/ Update page fault handlers to distinguish between different access modes that had caused the page fault.  
1411 6558 d 17 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 6562 d 13 h decky /kernel/trunk/ make hardware memory mapping more generic  
1303 6573 d 16 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 6577 d 19 h vana /kernel/trunk/arch/ VESA FB cut unwanted  
1291 6577 d 20 h vana /kernel/trunk/arch/amd64/src/boot/ VESA detection failure fix on amd64  
1289 6577 d 20 h vana /kernel/trunk/arch/ Amd64 framebuffer  
1288 6577 d 22 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 6580 d 12 h palkovsky /kernel/trunk/ Added means to make a simple action upon interrupt.  
1278 6580 d 16 h palkovsky /kernel/trunk/ Changed interrupt_control to preemption_control.  
1263 6581 d 22 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 6582 d 21 h jermar /kernel/trunk/arch/ Fixes in amd64 and ia32 ddi_iospace_enable_arch().  
1258 6583 d 12 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 6583 d 19 h jermar /kernel/trunk/arch/ Initialize amd64 and ia32 task iomapver generation counter.  
1256 6583 d 19 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 6583 d 22 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.		  
1252 6583 d 23 h palkovsky /kernel/trunk/arch/amd64/src/ Fix amd64 SMP boot when tss for AP CPU gets allocated in memory >20MB.  
1251 6584 d 19 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.		  
1247 6585 d 17 h vana /kernel/trunk/arch/amd64/src/smp/ Same 24 - > 32 bit lgdt patch on amd64 arch. Now both ia32 and amd64 platforms are able to have AP GDTs in all lowest 4GB of physicall memory.  
1242 6586 d 12 h jermar /kernel/trunk/arch/ This time really fix wrong definition of K_DATA_START.  
1241 6586 d 12 h jermar /kernel/trunk/arch/ Fix K_DATA_START section definition.  
1227 6589 d 18 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 6589 d 21 h jermar /kernel/trunk/ Make ia64 and sparc64 compile again.
Fix ia64 to set up inits in arch_pre_main().		  
1221 6590 d 11 h decky /kernel/trunk/ printf-related and other code cleanup  
1212 6590 d 16 h palkovsky /kernel/trunk/ Added uspace call to enable/disable interrupts.  
1203 6595 d 18 h jermar /kernel/trunk/arch/ Full implementation of amd64 and ia32 SYS_ENABLE_IOSPACE syscall.
Needs testing.		  
1201 6595 d 18 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.		  
1196 6596 d 21 h cejka /kernel/trunk/ Printf ported back from uspace to kernel.
Printf calls changed to match new conventions.
