4055 5555 d 7 h trochtova /branches/dd/ changes in trunk (rev 4054) merged into dd branch  
4042 5556 d 4 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 5563 d 1 h jermar /trunk/kernel/ Do not set sysinfo for uspace drivers directly in the kernel drivers.  
3981 5563 d 3 h jermar /trunk/kernel/genarch/src/kbd/ Get rid of unused variable.  
3963 5569 d 4 h jermar /trunk/kernel/ The kernel i8042 driver should be instance-neutral.  
3961 5569 d 5 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.
 
3959 5569 d 22 h jermar /trunk/kernel/genarch/src/kbd/ Remove unneeded stuff from kernel's ns16550 driver.  
3958 5569 d 23 h jermar /trunk/kernel/genarch/src/kbd/ Do not include the IPC stuff in the i8042 kernel driver.  
3947 5570 d 3 h jermar /trunk/ This is the evil commit. In particular, it does:

- introduces more powerful pseudo code for userspace IRQ top-half handlers
- changes the internals of IRQ dispatching
- simplifies the kernel's i8042 driver
- adapts the uspace i8042 driver to make use of the new pseudocode
- breaks all other architectures except ia32
- breaks almost all existing drivers
- breaks switching between uspace and kernel drivers
 
3941 5570 d 23 h jermar /trunk/kernel/ Let IRQ claim methods take irq_t * instead of the instance argument.  
3938 5571 d 4 h jermar /trunk/kernel/genarch/ Embed the ns16550 irq structure into the ns16550 instance structure.  
3934 5571 d 20 h jermar /trunk/kernel/ Improve the ns16550 driver.

- The driver support multiple instances.
- It still remembers the last registered IRQ in a global structure (cannot be
easily fixed now)
- Was converted to use PIO directly
 
3932 5571 d 22 h jermar /trunk/kernel/ Kill arch/drivers/ega.h. Provide one-stop shopping
place for architectures with ia32 legacy I/O space.
 
3931 5571 d 22 h jermar /trunk/kernel/genarch/ Improve the i8042 kernel driver (phase I).

- Convert the code to be instance-aware
- Still using hardcoded initialization from legacy IO address
- Use elegant i8042 register map for PIO
 
3928 5572 d 0 h jermar /trunk/kernel/ Kill arch/drivers/i8042.h.  
3927 5572 d 1 h jermar /trunk/kernel/genarch/ Nuke i8042_poll().  
3906 5575 d 21 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.
 
3900 5576 d 6 h jermar /trunk/ Get rid of CONFIG_NS16550_INTERRUPT_DRIVEN and CONFIG_I8042_INTERRUPT_DRIVEN.  
3877 5579 d 0 h decky /trunk/kernel/genarch/ remove (almost all) platform dependent code from drivers  
3714 5636 d 4 h decky /trunk/kernel/ do not waist resources if no keyboard driver is used  
3661 5652 d 23 h vana /trunk/ IA64: repair similators support  
3657 5653 d 8 h vana /trunk/ Legacy IRQ support, uspace NS16550 support, some minor changes  
3655 5654 d 0 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.
 
3646 5655 d 1 h jermar /trunk/kernel/ Initial support for interrupt driven driver for ns16550.  
3581 5671 d 22 h jermar /trunk/kernel/ Some cstyle.  
3577 5672 d 12 h vana /trunk/kernel/ Support for serial port console on IA64 as a compensation for keyboard - based on SPARC ns16550 driver  
2572 6075 d 15 h jermar /trunk/kernel/ Remove duplicit implementation of strlen() in kernel, rename is_digit(),
is_white() and co. to their standard names (e.g. isdigit(), isspace()) and
remove duplicit implementation of isdigit(). Fix cstyle in kernel printf()
implementation.
 
2516 6100 d 23 h vana /trunk/kernel/ IA64 rest of neaded changes to work with simics keyboard  
2321 6223 d 5 h decky /trunk/ keep mouse state in i8042_grab, unify keyboard and mouse IRQ handler
(this fixes ticket #12)
 
2089 6325 d 7 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes
 
2071 6336 d 0 h jermar /trunk/ (c) versus (C)  
1957 6418 d 8 h decky /trunk/kernel/ ia32: mouse support, mouse regrab is still broken  
1956 6418 d 9 h decky /trunk/kernel/ ia32: adopt new IRQ interface, mouse not tested yet  
1944 6426 d 3 h jermar /trunk/kernel/ Add mutual exclusion to keyboard grab and release
functions on sparc64, ppc32, mips32 and ia64.
 
1932 6428 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 6428 d 1 h jermar /trunk/ Add support for IPC notifications even for polled ns16550 based keyboard.  
1925 6428 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 6428 d 23 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 6431 d 1 h jermar /trunk/kernel/ Changes in ns16550 and z8530 drivers.
Add some stuff for IRQ notifications to irq_t.
 
1920 6431 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.
