2064 6472 d 2 h vana /trunk/ SIMICS added as a simulator kernel runs on  
2063 6472 d 6 h jermar /trunk/kernel/generic/src/lib/ Call big endian byte swap function instead of little endian.  
2062 6472 d 7 h jermar /trunk/kernel/generic/src/lib/ switch statement coding style fixes.  
2059 6481 d 12 h jermar /trunk/kernel/generic/ Improve indentation and formatting.  
2052 6487 d 7 h decky /trunk/kernel/generic/src/mm/ pretty-print slabs  
2051 6487 d 13 h decky /trunk/kernel/ quiet mode  
2050 6487 d 13 h decky /trunk/kernel/ benchmarking with statistics (initial)  
2048 6490 d 5 h jermar /trunk/ Formatting and indentation changes.  
2042 6492 d 7 h decky /trunk/kernel/ introduce uncounted threads, whose accounting doesn't affect accumulated task accounting
run tests in kconsole thread again
 
2041 6492 d 8 h decky /trunk/kernel/generic/src/proc/ revert 2040  
2040 6492 d 10 h decky /trunk/kernel/generic/src/proc/ add forgotten btree_remove()  
2039 6492 d 11 h decky /trunk/kernel/generic/ accumulate task accounting, run tests as separate kernel task  
2035 6493 d 9 h decky /trunk/kernel/generic/src/ more fancy kconsole output  
2032 6493 d 10 h decky /trunk/kernel/generic/src/proc/ proper initialization of last_cycle  
2030 6493 d 11 h decky /trunk/kernel/ thread CPU cycles accounting  
2027 6494 d 11 h decky /trunk/kernel/ cleanup kernel tests infrastructure  
2020 6495 d 5 h decky /trunk/kernel/ integrate more tests  
2019 6495 d 5 h decky /trunk/kernel/ prepare for new test infrastructure  
2015 6497 d 3 h jermar /trunk/ Rework support for virtually indexed cache.
Instead of repeatedly flushing the data cache, which was a huge overkill, refuse to create an illegal address alias
in the kernel (again) and allocate appropriate page color in userspace instead. Extend the detection also to
SYS_PHYSMEM_MAP syscall.

Add support for tracking physical memory areas mappable by SYS_PHYSMEM_MAP.

Lots of coding style changes.
 
2012 6500 d 1 h jermar /trunk/ Eliminate confusion between SYS_MAP_PHYSMEM and sys_physmem_map.
The syscall is to be called SYS_PHYSMEM_MAP from now on and the functions that participate in its implementation are
called *physmem_map().
 
2009 6502 d 2 h jermar /trunk/kernel/ Initial support for handling illegal virtual aliases on sparc64.  
2007 6505 d 1 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.
 
2005 6506 d 8 h decky /trunk/ update rd  
2002 6506 d 10 h decky /trunk/kernel/generic/ rd work  
2000 6508 d 13 h decky /trunk/kernel/ move files to more proper locations  
1999 6508 d 13 h decky /trunk/ start RAM disk support  
1981 6518 d 11 h jermar /trunk/kernel/ Indentation, formatting and minor changes.  
1972 6531 d 10 h jermar /trunk/ Modify selected function to consume less stack space.

Avoid flushw instruction in the sparc64 loader.
 
1954 6541 d 2 h jermar /trunk/ Minor changes. Some coding style fixes and also a type (tee vs. tree).
One AS -> as change.
 
1950 6545 d 6 h jermar /trunk/kernel/ Indentation changes and coding style fixes in slab.c and slab.h.  
1933 6550 d 2 h jermar /trunk/kernel/generic/ Implement efficient IPC notification cleanup.  
1932 6550 d 3 h jermar /trunk/kernel/ Do not copy notification config out of the IRQ structure.
Add the notify member, that toggles notifications on and off instead.
This is good for preventing other tasks from registering the notification
while the notification config is stored outside the IRQ structure.
It should also help to implement the cleanup code.
 
1929 6550 d 8 h decky /trunk/kernel/generic/src/console/ ipc_irq_send_msg(NULL, 0, 0, 0) is definitively a bug  
1926 6550 d 13 h decky /trunk/kernel/ cleanup for new IRQ subsystem  
1924 6551 d 2 h jermar /trunk/kernel/generic/ For the sake of clarity, get rid of negative INR for virtual interrupts.
This way, the code can hurt performance on systems where the non-negative klog INR overlaps
with a frequently used INR such as system clock on amd64 and ia32.
 
1923 6551 d 3 h jermar /trunk/ Replace the old IRQ dispatcher and IPC notifier with new implementation.
Note that all architectures except for sparc64 are now broken
and don't even compile.
 
1922 6552 d 11 h jermar /trunk/kernel/ More IRQ stuff.
Modify the IRQ hash table functions to support lookup based on inr and devno.
Add method member to irq_t.
 
1921 6553 d 4 h jermar /trunk/kernel/ Changes in ns16550 and z8530 drivers.
Add some stuff for IRQ notifications to irq_t.
 
1920 6553 d 12 h jermar /trunk/kernel/ Move the new IRQ redirector to ddi/.
Add function for assigning unique device numbers.
Change sparc64/drivers/kbd.c to assign devno to keyboard.
 
1919 6554 d 3 h jermar /trunk/kernel/ Prototypical implementation of new IRQ redirector in sparc64.
The new code can support shared IRQs in kernel (and multiple IRQs per device).
Userspace support is yet to be written.
The only architecture that uses this code is actually sparc64 only.
