2009 6385 d 9 h jermar /trunk/kernel/ Initial support for handling illegal virtual aliases on sparc64.  
2007 6388 d 8 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 6389 d 15 h decky /trunk/ update rd  
2002 6389 d 17 h decky /trunk/kernel/generic/ rd work  
2000 6391 d 20 h decky /trunk/kernel/ move files to more proper locations  
1999 6391 d 20 h decky /trunk/ start RAM disk support  
1981 6401 d 18 h jermar /trunk/kernel/ Indentation, formatting and minor changes.  
1972 6414 d 17 h jermar /trunk/ Modify selected function to consume less stack space.

Avoid flushw instruction in the sparc64 loader.		  
1954 6424 d 9 h jermar /trunk/ Minor changes. Some coding style fixes and also a type (tee vs. tree).
One AS -> as change.		  
1950 6428 d 13 h jermar /trunk/kernel/ Indentation changes and coding style fixes in slab.c and slab.h.  
1933 6433 d 9 h jermar /trunk/kernel/generic/ Implement efficient IPC notification cleanup.  
1932 6433 d 10 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 6433 d 15 h decky /trunk/kernel/generic/src/console/ ipc_irq_send_msg(NULL, 0, 0, 0) is definitively a bug  
1926 6433 d 20 h decky /trunk/kernel/ cleanup for new IRQ subsystem  
1924 6434 d 9 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 6434 d 10 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 6435 d 18 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 6436 d 11 h jermar /trunk/kernel/ Changes in ns16550 and z8530 drivers.
Add some stuff for IRQ notifications to irq_t.		  
1920 6436 d 19 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 6437 d 10 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.
