4605 5618 d 5 h decky /branches/snapshot/ add task snapshoting branch  
4311 5690 d 6 h decky /trunk/ change the way how input devices are wired together according to ticket #44
(also the proposal http://lists.modry.cz/cgi-bin/private/helenos-devel/2009-March/002507.html)		  
4148 5724 d 8 h decky /trunk/ as kernel little brother drivers are not needed anymore, the device numbers do not have to be correlated between kernel and uspace in any way
introduce new syscall sys_device_assign_devno() for generating system-wide unique device numbers for uspace		  
4119 5729 d 10 h decky /trunk/ get back support for framebuffer and keyboard for sparc64 (generic)  
4094 5730 d 1 h decky /trunk/kernel/genarch/ update for the new scheme of wiring device drivers to keyboard/serial modules  
4042 5735 d 3 h jermar /trunk/ Complete emancipation of kernel serial controller drivers (i8042, ns16550 and
z8530). Provide a common keyboard module for PC and Sun keyboards. The serial
line module is still to follow.		  
3982 5742 d 0 h jermar /trunk/kernel/ Do not set sysinfo for uspace drivers directly in the kernel drivers.  
3961 5748 d 4 h jermar /trunk/ Unbreak sparc64.
Due to the lack of userspace bus drivers for the z8530 and ns16550,
we are currently handling exactly one interrupt from these devices
in userspace.		  
3941 5749 d 22 h jermar /trunk/kernel/ Let IRQ claim methods take irq_t * instead of the instance argument.  
3906 5754 d 20 h jermar /trunk/kernel/ IRQ handlers are using one superfluous argument and an unused elipsis.
On the other hand, IRQ claim functions would need to be passed the instance
argument.		  
3655 5832 d 22 h jermar /trunk/kernel/ Add additional members to the irq_t structure so that an interrupt-driven driver
does not need to know how to clear the level interrupt. The z8530 was modified
in this way and is much more generic. The ns16550 driver has also been modified,
but awaits testing. The sparc64 interrupt mapping and dispatch code is now using
the new info and calls the clear-interrupt-routine itself.		  
2089 6504 d 5 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes		  
2071 6514 d 22 h jermar /trunk/ (c) versus (C)  
1944 6605 d 1 h jermar /trunk/kernel/ Add mutual exclusion to keyboard grab and release
functions on sparc64, ppc32, mips32 and ia64.		  
1932 6606 d 22 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 6607 d 0 h jermar /trunk/ Add support for IPC notifications even for polled ns16550 based keyboard.  
1925 6607 d 21 h jermar /trunk/kernel/genarch/src/kbd/ Support for grabbing and releasing z8530 keyboard for sparc64.
We might later add some locking.		  
1923 6607 d 22 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 6609 d 23 h jermar /trunk/kernel/ Changes in ns16550 and z8530 drivers.
Add some stuff for IRQ notifications to irq_t.		  
1920 6610 d 7 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.
