2007 6548 d 22 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.		  
1994 6558 d 7 h decky /trunk/ Add BGR 0888 visual for Ultra 60  
1993 6558 d 8 h decky /trunk/ make framebuffer code more generic  
1991 6559 d 1 h jermar /trunk/kernel/genarch/src/fb/ The prefered switch statement indentation is the one replaced by the previous commit :-)  
1990 6559 d 4 h decky /trunk/kernel/genarch/src/fb/ framebuffer cleanup  
1981 6562 d 8 h jermar /trunk/kernel/ Indentation, formatting and minor changes.  
1974 6573 d 2 h jermar /trunk/kernel/genarch/src/ofw/ Rewrite OFW device tree traversal algorithms to iterate over the list of peers rather than recurse on each
peer node. This saves us from big troubles with stack overflows.		  
1972 6575 d 7 h jermar /trunk/ Modify selected function to consume less stack space.

Avoid flushw instruction in the sparc64 loader.		  
1957 6584 d 8 h decky /trunk/kernel/ ia32: mouse support, mouse regrab is still broken  
1956 6584 d 9 h decky /trunk/kernel/ ia32: adopt new IRQ interface, mouse not tested yet  
1944 6592 d 3 h jermar /trunk/kernel/ Add mutual exclusion to keyboard grab and release
functions on sparc64, ppc32, mips32 and ia64.		  
1932 6594 d 0 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.		  
1931 6594 d 1 h jermar /trunk/ Add support for IPC notifications even for polled ns16550 based keyboard.  
1925 6594 d 23 h jermar /trunk/kernel/genarch/src/kbd/ Support for grabbing and releasing z8530 keyboard for sparc64.
We might later add some locking.		  
1923 6595 d 0 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.		  
1921 6597 d 1 h jermar /trunk/kernel/ Changes in ns16550 and z8530 drivers.
Add some stuff for IRQ notifications to irq_t.		  
1920 6597 d 9 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 6598 d 0 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.		  
1912 6604 d 9 h jermar /trunk/kernel/ Separate mapping of EBUS interrupts into two parts: EBUS and PCI.  
1911 6604 d 22 h jermar /trunk/kernel/ Add support for interrupt mapping in the Sabre PCI controller.
Add support for PCI and EBUS interrupt mapping via the OpenFirmware device tree.
Unfortunatelly, the code is not capable enough to earn single ns16550 interrupt.
I suspect something needs to be enabled in the EBUS registers.
