1935 6461 d 7 h decky /trunk/kernel/generic/include/ add function type  
1934 6461 d 8 h decky /trunk/kernel/arch/ppc32/src/drivers/ remove grab (not needed)  
1933 6461 d 19 h jermar /trunk/kernel/generic/ Implement efficient IPC notification cleanup.  
1932 6461 d 20 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 6461 d 21 h jermar /trunk/ Add support for IPC notifications even for polled ns16550 based keyboard.  
1930 6462 d 1 h decky /trunk/kernel/arch/ppc64/ ppc64: make it compile again  
1929 6462 d 1 h decky /trunk/kernel/generic/src/console/ ipc_irq_send_msg(NULL, 0, 0, 0) is definitively a bug  
1928 6462 d 1 h decky /trunk/ ppc32: update for new IRQ subsystem (there is still a bug left)  
1927 6462 d 1 h decky /trunk/kernel/generic/include/ remove dummy definitions (which tent to lead to mysterious bugs)  
1926 6462 d 6 h decky /trunk/kernel/ cleanup for new IRQ subsystem  
1925 6462 d 19 h jermar /trunk/kernel/genarch/src/kbd/ Support for grabbing and releasing z8530 keyboard for sparc64.
We might later add some locking.		  
1924 6462 d 19 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 6462 d 20 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 6464 d 4 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 6464 d 21 h jermar /trunk/kernel/ Changes in ns16550 and z8530 drivers.
Add some stuff for IRQ notifications to irq_t.		  
1920 6465 d 5 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 6465 d 20 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.		  
1918 6469 d 20 h jermar /trunk/kernel/arch/sparc64/src/mm/ Omitted comma.  
1917 6469 d 21 h jermar /trunk/ sparc64 work:
- hw_map() can now support up to 8M requests
- CPU stacks are now locked in DTLB of the respective processor
- kernel in the boot phase no longer relies on the stack provided by OpenFirmware
- instead of of doing FLUSHW during kernel startup, simply set the
window state registers to the wanted state
- NWINDOW -> NWINDOWS
- Add/fix some comments and copyrights.		  
1916 6470 d 19 h jermar /trunk/kernel/arch/sparc64/src/trap/ Small change of code organization.
No functional difference.
