4055 5544 d 23 h trochtova /branches/dd/ changes in trunk (rev 4054) merged into dd branch  
4042 5545 d 20 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 5552 d 17 h jermar /trunk/kernel/ Do not set sysinfo for uspace drivers directly in the kernel drivers.  
3981 5552 d 19 h jermar /trunk/kernel/genarch/src/kbd/ Get rid of unused variable.  
3963 5558 d 20 h jermar /trunk/kernel/ The kernel i8042 driver should be instance-neutral.  
3961 5558 d 21 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 5559 d 14 h jermar /trunk/kernel/genarch/src/kbd/ Remove unneeded stuff from kernel's ns16550 driver.  
3958 5559 d 15 h jermar /trunk/kernel/genarch/src/kbd/ Do not include the IPC stuff in the i8042 kernel driver.  
3947 5559 d 19 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 5560 d 15 h jermar /trunk/kernel/ Let IRQ claim methods take irq_t * instead of the instance argument.  
3938 5560 d 20 h jermar /trunk/kernel/genarch/ Embed the ns16550 irq structure into the ns16550 instance structure.  
3934 5561 d 12 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 5561 d 14 h jermar /trunk/kernel/ Kill arch/drivers/ega.h. Provide one-stop shopping
place for architectures with ia32 legacy I/O space.		  
3931 5561 d 14 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 5561 d 16 h jermar /trunk/kernel/ Kill arch/drivers/i8042.h.  
3927 5561 d 17 h jermar /trunk/kernel/genarch/ Nuke i8042_poll().  
3906 5565 d 13 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 5565 d 22 h jermar /trunk/ Get rid of CONFIG_NS16550_INTERRUPT_DRIVEN and CONFIG_I8042_INTERRUPT_DRIVEN.  
3877 5568 d 16 h decky /trunk/kernel/genarch/ remove (almost all) platform dependent code from drivers  
3714 5625 d 20 h decky /trunk/kernel/ do not waist resources if no keyboard driver is used
