1833 6531 d 18 h decky /trunk/kernel/ more sophisticated initial stack handling  
1826 6532 d 1 h decky /trunk/kernel/generic/src/main/ some debugging output  
1822 6532 d 7 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 6535 d 19 h decky /trunk/kernel/generic/ initial security context support  
1819 6535 d 20 h decky /trunk/kernel/generic/include/ formatting changes  
1812 6540 d 4 h decky /trunk/kernel/ move macro and cleanup  
1793 6550 d 7 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 6551 d 1 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 6553 d 0 h decky / move kernel/trunk, uspace/trunk and boot/trunk to trunk/kernel, trunk/uspace and trunk/boot  
1780 6560 d 1 h jermar /kernel/trunk/ Replace old __u?? types with respective C99 variants (e.g. uint32_t, int64_t, uintptr_t etc.).  
1767 6568 d 8 h palkovsky /kernel/trunk/ Remove unneeded FRAME_PANIC.
Fix some things broken by last commit.		  
1766 6568 d 9 h palkovsky /kernel/trunk/ Changed frame_alloc call, cleaned a lot of stuff, fixed some not-perfectly-correct error handling.  
1760 6571 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 6574 d 6 h jermar /kernel/trunk/ Cleanup of comments.  
1735 6576 d 8 h decky /kernel/trunk/ make kernel prints case consistent  
1731 6576 d 18 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 6576 d 18 h decky /kernel/trunk/generic/src/main/ coding style changes  
1712 6577 d 23 h palkovsky /kernel/trunk/generic/ Send to uspace notification about end of kconsole mode.  
1708 6578 d 7 h jermar /kernel/trunk/ Fix some broken doxygen comments.  
1705 6580 d 7 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 6580 d 10 h cejka /kernel/trunk/ Fixed first letter size of subgroup name in Others.  
1702 6581 d 4 h cejka /kernel/trunk/ Kernel doxygen comments updated.  
1700 6581 d 7 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 6581 d 23 h jermar /kernel/trunk/generic/src/ipc/ Improve comments.
Replace 'process' with 'task'.		  
1695 6583 d 1 h jermar /kernel/trunk/generic/src/console/ Inform the user about the kernel relinquishing the console on continue command.  
1693 6583 d 2 h palkovsky /kernel/trunk/generic/ Modified ipc/irq to be able to pass up to 3 arguments to userspace.  
1687 6584 d 5 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 6584 d 8 h jermar /kernel/trunk/ #ifdef more debugging printf()'s.  
1682 6584 d 11 h palkovsky /kernel/trunk/ Fast framebuffer scrolling in kconsole. Eats some memory though.  
1681 6584 d 19 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 6584 d 19 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 6585 d 4 h palkovsky /kernel/trunk/generic/src/mm/ Fixed error in page number computing, that could almost never appear.  
1676 6585 d 5 h jermar /kernel/trunk/generic/src/proc/ Forgotten interrupts_restore().  
1669 6586 d 2 h palkovsky /kernel/trunk/generic/src/ipc/ Small consitency ipc update.  
1667 6586 d 2 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 6586 d 5 h palkovsky /kernel/trunk/ Slightly better test.
Made call keys work on ia64.		  
1662 6586 d 9 h palkovsky /kernel/trunk/generic/src/main/ Responsive kconsole after test finished.  
1661 6586 d 10 h jermar /kernel/trunk/generic/ Collect Undead threads while waiting to join uinit.
Rename ktaskkill to ktaskgc.		  
1659 6586 d 10 h vana /kernel/trunk/generic/src/main/ No uspace if tests  
1643 6587 d 8 h palkovsky /kernel/trunk/generic/ IPC made faster in non-debug mode.
