4092 5572 d 8 h decky /trunk/kernel/genarch/ wire keyboard/serial module and device drivers in a more obvious way
(first a device driver is initialized and then it is connected to the generic module)		  
4078 5572 d 13 h decky /trunk/kernel/genarch/ add dummy serial line input and output drivers  
4052 5576 d 15 h jermar /trunk/kernel/genarch/src/srln/ Add a new line - gcc is very picky lately.  
4043 5577 d 9 h jermar /trunk/ Serial line module.  
4042 5577 d 9 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.		  
4022 5581 d 4 h svoboda /trunk/ Move multiboot parsing to genarch/*/multiboot and adapt it for use with both ia32 and amd64. Multiboot info parsing now supported on amd64, too.  
4011 5582 d 4 h svoboda /trunk/kernel/ String functions should be declared in string.h (and implemented in string.c) in the kernel.  
3994 5582 d 12 h decky /trunk/kernel/genarch/src/drivers/ega/ make sure the EGA framebuffer is initialized with proper attributes  
3982 5584 d 7 h jermar /trunk/kernel/ Do not set sysinfo for uspace drivers directly in the kernel drivers.  
3981 5584 d 8 h jermar /trunk/kernel/genarch/src/kbd/ Get rid of unused variable.  
3975 5585 d 12 h decky /trunk/kernel/genarch/src/drivers/ega/ keep original contents of the EGA framebuffer,
make sure the cursor is on		  
3963 5590 d 10 h jermar /trunk/kernel/ The kernel i8042 driver should be instance-neutral.  
3961 5590 d 10 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 5591 d 4 h jermar /trunk/kernel/genarch/src/kbd/ Remove unneeded stuff from kernel's ns16550 driver.  
3958 5591 d 4 h jermar /trunk/kernel/genarch/src/kbd/ Do not include the IPC stuff in the i8042 kernel driver.  
3947 5591 d 8 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 5592 d 5 h jermar /trunk/kernel/ Let IRQ claim methods take irq_t * instead of the instance argument.  
3940 5592 d 8 h decky /trunk/kernel/ make hw_area API more generic
this allows mapping of EGA VRAM on ia32/amd64		  
3938 5592 d 9 h jermar /trunk/kernel/genarch/ Embed the ns16550 irq structure into the ns16550 instance structure.  
3934 5593 d 2 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
