1968 6413 d 12 h jermar /tags/ Canonize pre-0.2.0.3 tags: remove inner branches, tags and trunk directories.
The change now should reflect how those releases looked like after checkout.		  
1965 6413 d 12 h jermar /tags/0.2.0.1/ Tagging release 0.2.0.1  
1692 6551 d 17 h palkovsky /kernel/trunk/arch/amd64/include/ Fix prein/predec instructions to be the same as on ia32.  
1595 6557 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.		  
1511 6560 d 19 h palkovsky /kernel/trunk/arch/ Remove __address from include file included by uspace  
1477 6562 d 5 h decky /kernel/trunk/arch/ cleanup  
1473 6562 d 14 h decky /kernel/trunk/ kernel support for text-only framebuffer  
1423 6566 d 20 h jermar /kernel/trunk/ Update page fault handlers to distinguish between different access modes that had caused the page fault.  
1411 6569 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.		  
1292 6588 d 19 h vana /kernel/trunk/arch/ VESA FB cut unwanted  
1289 6588 d 20 h vana /kernel/trunk/arch/ Amd64 framebuffer  
1288 6588 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.		  
1256 6594 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.		  
1251 6595 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.		  
1212 6601 d 16 h palkovsky /kernel/trunk/ Added uspace call to enable/disable interrupts.  
1203 6606 d 17 h jermar /kernel/trunk/arch/ Full implementation of amd64 and ia32 SYS_ENABLE_IOSPACE syscall.
Needs testing.		  
1201 6606 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.		  
1187 6610 d 16 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 6610 d 18 h jermar /kernel/trunk/arch/ Replace assembly from pm.c with new inline functions defined in asm.h.  
1184 6610 d 19 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.
