1833 6548 d 19 h decky /trunk/kernel/ more sophisticated initial stack handling  
1826 6549 d 2 h decky /trunk/kernel/generic/src/main/ some debugging output  
1822 6549 d 8 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 6552 d 20 h decky /trunk/kernel/generic/ initial security context support  
1793 6567 d 8 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 6568 d 2 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 6570 d 1 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1780 6577 d 2 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1767 6585 d 9 h palkovsky /kernel/trunk/ Remove unneeded FRAME_PANIC.
Fix some things broken by last commit.		  
1766 6585 d 9 h palkovsky /kernel/trunk/ Changed frame_alloc call, cleaned a lot of stuff, fixed some not-perfectly-correct error handling.  
1760 6588 d 3 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 6591 d 7 h jermar /kernel/trunk/ Cleanup of comments.  
1735 6593 d 9 h decky /kernel/trunk/ make kernel prints case consistent  
1731 6593 d 19 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 6593 d 19 h decky /kernel/trunk/generic/src/main/ coding style changes  
1712 6595 d 0 h palkovsky /kernel/trunk/generic/ Send to uspace notification about end of kconsole mode.  
1708 6595 d 8 h jermar /kernel/trunk/ Fix some broken doxygen comments.  
1705 6597 d 8 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 6597 d 11 h cejka /kernel/trunk/ Fixed first letter size of subgroup name in Others.  
1702 6598 d 5 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1700 6598 d 8 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 6598 d 23 h jermar /kernel/trunk/generic/src/ipc/ Improve comments.
Replace 'process' with 'task'.		  
1695 6600 d 2 h jermar /kernel/trunk/generic/src/console/ Inform the user about the kernel relinquishing the console on continue command.  
1693 6600 d 2 h palkovsky /kernel/trunk/generic/ Modified ipc/irq to be able to pass up to 3 arguments to userspace.  
1687 6601 d 6 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 6601 d 9 h jermar /kernel/trunk/ #ifdef more debugging printf()'s.  
1682 6601 d 12 h palkovsky /kernel/trunk/ Fast framebuffer scrolling in kconsole. Eats some memory though.  
1681 6601 d 20 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 6601 d 20 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 6602 d 5 h palkovsky /kernel/trunk/generic/src/mm/ Fixed error in page number computing, that could almost never appear.  
1676 6602 d 6 h jermar /kernel/trunk/generic/src/proc/ Forgotten interrupts_restore().  
1669 6603 d 2 h palkovsky /kernel/trunk/generic/src/ipc/ Small consitency ipc update.  
1667 6603 d 3 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 6603 d 6 h palkovsky /kernel/trunk/ Slightly better test.
Made call keys work on ia64.		  
1662 6603 d 10 h palkovsky /kernel/trunk/generic/src/main/ Responsive kconsole after test finished.  
1661 6603 d 10 h jermar /kernel/trunk/generic/ Collect Undead threads while waiting to join uinit.
Rename ktaskkill to ktaskgc.		  
1659 6603 d 11 h vana /kernel/trunk/generic/src/main/ No uspace if tests  
1643 6604 d 8 h palkovsky /kernel/trunk/generic/ IPC made faster in non-debug mode.  
1636 6604 d 19 h jermar /kernel/trunk/ Move comment.

Do TLB shootdown also when allocating new ASID.		  
1628 6604 d 20 h decky /kernel/trunk/ fixes
