1967 6404 d 7 h jermar /tags/0.2.0.3/ Tagging release 0.2.0.3  
1833 6491 d 4 h decky /trunk/kernel/ more sophisticated initial stack handling  
1826 6491 d 11 h decky /trunk/kernel/generic/src/main/ some debugging output  
1822 6491 d 17 h jermar /trunk/ sparc64 work.
1. Formatting fixes.
2. When writing to DMMU ASI's, simple membar() can be used in place of flush().
3. Substantial changes in the way the TLB is taken over.
4. Remove unneeded functions.

This is the first revision that also runs on a real world Ultra 5 with UltraSPARC IIi
processor.

Note that 3. needs further work as the current implementation depends on the fact
that the compiler will use registers for local variables in take_over_tlb_and_tt().
Rewrite of that function into assembly is to follow.		  
1820 6495 d 5 h decky /trunk/kernel/generic/ initial security context support  
1819 6495 d 6 h decky /trunk/kernel/generic/include/ formatting changes  
1812 6499 d 15 h decky /trunk/kernel/ move macro and cleanup  
1793 6509 d 17 h jermar /trunk/kernel/ Change hw_map() on sparc64 to use virtual addresses that are
beyond the end of physical memory. It is beneficial in two
ways: first, physical memory is no longer being wasted by
otherwise necessary calls to frame_alloc() and, second,
virtual addresses for devices are now correctly allocated
and do not overlap with the 4M TLB-locked mapping for
kernel text and data.		  
1790 6510 d 11 h jermar /trunk/ Remove OpenFirmware calls from kernel/ entirely.

Switch the sparc64 port to use bootinfo.

Copy memcpy from boot/ to sparc64 kernel/ and
adjust it for memcpy_from/to_uspace.		  
1787 6512 d 10 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1780 6519 d 12 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1767 6527 d 19 h palkovsky /kernel/trunk/ Remove unneeded FRAME_PANIC.
Fix some things broken by last commit.		  
1766 6527 d 19 h palkovsky /kernel/trunk/ Changed frame_alloc call, cleaned a lot of stuff, fixed some not-perfectly-correct error handling.  
1760 6530 d 13 h palkovsky /kernel/trunk/ Changed interface of frame_alloc/free to use address of frame instead of the pfn.
This makes it impossible to use >4GB of memory on 32-bit machines, but who cares...		  
1757 6533 d 16 h jermar /kernel/trunk/ Cleanup of comments.  
1735 6535 d 18 h decky /kernel/trunk/ make kernel prints case consistent  
1731 6536 d 4 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.		  
1729 6536 d 4 h decky /kernel/trunk/generic/src/main/ coding style changes  
1712 6537 d 9 h palkovsky /kernel/trunk/generic/ Send to uspace notification about end of kconsole mode.  
1708 6537 d 18 h jermar /kernel/trunk/ Fix some broken doxygen comments.  
1705 6539 d 17 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 6539 d 21 h cejka /kernel/trunk/ Fixed first letter size of subgroup name in Others.  
1702 6540 d 14 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1700 6540 d 17 h palkovsky /kernel/trunk/generic/src/mm/ Fixed frame allocator to allocate correct number of frames for configuration.
(It couldn't fail before, but in some circumstances it could allocate more
then needed).		  
1698 6541 d 9 h jermar /kernel/trunk/generic/src/ipc/ Improve comments.
Replace 'process' with 'task'.		  
1695 6542 d 11 h jermar /kernel/trunk/generic/src/console/ Inform the user about the kernel relinquishing the console on continue command.  
1693 6542 d 12 h palkovsky /kernel/trunk/generic/ Modified ipc/irq to be able to pass up to 3 arguments to userspace.  
1687 6543 d 15 h jermar /kernel/trunk/generic/src/proc/ Fix double thread_join() in ktaskgc.
In thread_create(), lock TASK with interrupts disabled again.
thread_join_timeout() can use ordinary waitq_sleep_timeout().		  
1684 6543 d 19 h jermar /kernel/trunk/ #ifdef more debugging printf()'s.  
1682 6543 d 21 h palkovsky /kernel/trunk/ Fast framebuffer scrolling in kconsole. Eats some memory though.  
1681 6544 d 5 h jermar /kernel/trunk/generic/src/synch/ Avoid tricky race condition between waitq_wakeup() and the pair
of waitq_timeouted_sleep() and waitq_interrupt_sleep().
Mutual exclusion != Synchronization.		  
1680 6544 d 5 h jermar /kernel/trunk/generic/src/proc/ Add interrupts_restore() to thread_join_timeout(). Note that this is not necessary, because
waitq_sleep_finish() does the job for thread_join_timeout(). However, the code looks more
correct in the form with interrupts_restore().		  
1677 6544 d 14 h palkovsky /kernel/trunk/generic/src/mm/ Fixed error in page number computing, that could almost never appear.  
1676 6544 d 15 h jermar /kernel/trunk/generic/src/proc/ Forgotten interrupts_restore().  
1669 6545 d 12 h palkovsky /kernel/trunk/generic/src/ipc/ Small consitency ipc update.  
1667 6545 d 13 h jermar /kernel/trunk/ Print spurious interrupt messages only when compiled with CONFIG_DEBUG.
Print warning about looping spinlock only after 100000000 unsuccessfull attempts to gain the spinlock.		  
1666 6545 d 16 h palkovsky /kernel/trunk/ Slightly better test.
Made call keys work on ia64.		  
1662 6545 d 20 h palkovsky /kernel/trunk/generic/src/main/ Responsive kconsole after test finished.  
1661 6545 d 20 h jermar /kernel/trunk/generic/ Collect Undead threads while waiting to join uinit.
Rename ktaskkill to ktaskgc.		  
1659 6545 d 20 h vana /kernel/trunk/generic/src/main/ No uspace if tests
