2018 6450 d 14 h decky /trunk/kernel/ rename rdtsc() to get_cycle()  
2007 6460 d 9 h jermar /trunk/kernel/ Introduce page colors. So far, only sparc64 uses correct page color bits. Other architectures have a dummy define
specifying zero bits for a page color.

There is a new check of page color in as_area_share(). Because of lack of support for this in the userspace, the
check has been #ifef'ed out.		  
2003 6461 d 16 h decky /trunk/kernel/arch/ cleanup endian conversion macros  
1957 6495 d 19 h decky /trunk/kernel/ ia32: mouse support, mouse regrab is still broken  
1956 6495 d 20 h decky /trunk/kernel/ ia32: adopt new IRQ interface, mouse not tested yet  
1939 6504 d 14 h decky /trunk/ ia32: fix compilation, keyboard not checked yet  
1901 6526 d 16 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 6534 d 9 h jermar /trunk/kernel/ sparc64 work:
- Experimental support for TSB (Translation Storage Buffer).		  
1890 6534 d 20 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 6535 d 11 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 6538 d 14 h jermar /trunk/ C99 compliant header guards (hopefully) everywhere in the kernel.
Formatting and indentation changes.
Small improvements in sparc64.		  
1882 6539 d 18 h jermar /trunk/kernel/ Support for sparc64 FPU context.  
1854 6554 d 20 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 6590 d 7 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 6590 d 19 h decky /trunk/kernel/arch/ unify bootstrapping  
1787 6603 d 13 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1780 6610 d 14 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1731 6627 d 7 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 6630 d 23 h jermar /kernel/trunk/arch/ Put sparc64 interrupt stuff under the Interrupt group in Doxygen-generated documentation.  
1702 6631 d 17 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1697 6632 d 12 h palkovsky /kernel/trunk/arch/ Fixed incorrect atomic_postinc/postdec...again...  
1691 6633 d 15 h palkovsky /kernel/trunk/arch/ia32/include/ Fix either bad compiler or bad code. The net result is better
optimization in GCC		  
1595 6639 d 0 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 6640 d 12 h jermar /kernel/trunk/ Make use of thread_join_timeout() and thread_detach() in kernel.

Improved comments in slab.h.		  
1511 6642 d 17 h palkovsky /kernel/trunk/arch/ Remove __address from include file included by uspace  
1477 6644 d 2 h decky /kernel/trunk/arch/ cleanup  
1473 6644 d 12 h decky /kernel/trunk/ kernel support for text-only framebuffer  
1468 6644 d 15 h jermar /kernel/trunk/ Function for destroying address space for which there is no other reference in the kernel.  
1434 6647 d 13 h palkovsky /kernel/trunk/ Added 'realtime' clock interface.
Added some asm macros as memory barriers.
Added drift computing for mips platform.		  
1423 6648 d 18 h jermar /kernel/trunk/ Update page fault handlers to distinguish between different access modes that had caused the page fault.  
1411 6651 d 14 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 6663 d 19 h jermar /kernel/trunk/ Change coding style in vesa.c and do some minor changes.  
1292 6670 d 16 h vana /kernel/trunk/arch/ VESA FB cut unwanted  
1289 6670 d 18 h vana /kernel/trunk/arch/ Amd64 framebuffer  
1288 6670 d 19 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 6670 d 21 h vana /kernel/trunk/ ia32 VESA FB support  
1256 6676 d 16 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 6677 d 17 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 6683 d 13 h palkovsky /kernel/trunk/ Added uspace call to enable/disable interrupts.  
1203 6688 d 15 h jermar /kernel/trunk/arch/ Full implementation of amd64 and ia32 SYS_ENABLE_IOSPACE syscall.
Needs testing.
