1901 6494 d 1 h jermar /trunk/kernel/ Make SMP related parts of main.c more generic.
Move initialization of local APIC to architecture specific code.
Add arch_post_cpu_init() to support the above.
 
1891 6501 d 18 h jermar /trunk/kernel/ sparc64 work:
- Experimental support for TSB (Translation Storage Buffer).
 
1890 6502 d 4 h jermar /trunk/ - Create a dedicated slab cache for as_t objects and switch from malloc/free to slab_alloc/slab_free for
them.

- Slightly fix and improve both the kernel and userspace atomic_add() on sparc64.

- More TSB work on the sparc64 front.
 
1889 6502 d 20 h jermar /trunk/kernel/ Fix bug in mm/as.c:
- as_area_destroy() should not work with AS but as

sparc64 work:
- start implementing TSB support
 
1888 6505 d 23 h jermar /trunk/ C99 compliant header guards (hopefully) everywhere in the kernel.
Formatting and indentation changes.
Small improvements in sparc64.
 
1882 6507 d 3 h jermar /trunk/kernel/ Support for sparc64 FPU context.  
1854 6522 d 5 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.
 
1817 6557 d 15 h decky /trunk/kernel/arch/ xen32 work: create identity mapping for the main memory zone,
make several dummy modifications to get to the banner
 
1811 6558 d 4 h decky /trunk/kernel/arch/ unify bootstrapping  
1787 6570 d 22 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1780 6577 d 23 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1731 6594 d 15 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.
 
1703 6598 d 8 h jermar /kernel/trunk/arch/ Put sparc64 interrupt stuff under the Interrupt group in Doxygen-generated documentation.  
1702 6599 d 2 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1697 6599 d 20 h palkovsky /kernel/trunk/arch/ Fixed incorrect atomic_postinc/postdec...again...  
1691 6601 d 0 h palkovsky /kernel/trunk/arch/ia32/include/ Fix either bad compiler or bad code. The net result is better
optimization in GCC
 
1595 6606 d 9 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.
 
1576 6607 d 20 h jermar /kernel/trunk/ Make use of thread_join_timeout() and thread_detach() in kernel.

Improved comments in slab.h.
 
1511 6610 d 1 h palkovsky /kernel/trunk/arch/ Remove __address from include file included by uspace  
1477 6611 d 11 h decky /kernel/trunk/arch/ cleanup  
1473 6611 d 20 h decky /kernel/trunk/ kernel support for text-only framebuffer  
1468 6612 d 0 h jermar /kernel/trunk/ Function for destroying address space for which there is no other reference in the kernel.  
1434 6614 d 22 h palkovsky /kernel/trunk/ Added 'realtime' clock interface.
Added some asm macros as memory barriers.
Added drift computing for mips platform.
 
1423 6616 d 3 h jermar /kernel/trunk/ Update page fault handlers to distinguish between different access modes that had caused the page fault.  
1411 6618 d 23 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.
 
1310 6631 d 3 h jermar /kernel/trunk/ Change coding style in vesa.c and do some minor changes.  
1292 6638 d 1 h vana /kernel/trunk/arch/ VESA FB cut unwanted  
1289 6638 d 2 h vana /kernel/trunk/arch/ Amd64 framebuffer  
1288 6638 d 4 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.
 
1287 6638 d 6 h vana /kernel/trunk/ ia32 VESA FB support  
1256 6644 d 1 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 6645 d 2 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 6650 d 22 h palkovsky /kernel/trunk/ Added uspace call to enable/disable interrupts.  
1203 6656 d 0 h jermar /kernel/trunk/arch/ Full implementation of amd64 and ia32 SYS_ENABLE_IOSPACE syscall.
Needs testing.
 
1201 6656 d 0 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 6659 d 23 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 6660 d 0 h jermar /kernel/trunk/arch/ Replace assembly from pm.c with new inline functions defined in asm.h.  
1184 6660 d 2 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.
 
1112 6681 d 6 h palkovsky /kernel/trunk/ Added basic kernel infrastructure for ThreadLocalStorage(TLS) for
ia32(complete),amd64(complete),mips32(missing emulation of rdhwr instruction).
 
1104 6681 d 23 h jermar /kernel/trunk/ Define atomic_t only once in atomic.h
Change the encapsulated counter type to long so that it supports negative values as well.
