4022 5582 d 23 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.  
4021 5583 d 0 h jermar /trunk/kernel/ There is no need to define ioport{8,16,32}_t types for each architecture separately.  
4011 5583 d 23 h svoboda /trunk/kernel/ String functions should be declared in string.h (and implemented in string.c) in the kernel.  
3994 5584 d 6 h decky /trunk/kernel/genarch/src/drivers/ega/ make sure the EGA framebuffer is initialized with proper attributes  
3982 5586 d 1 h jermar /trunk/kernel/ Do not set sysinfo for uspace drivers directly in the kernel drivers.  
3981 5586 d 3 h jermar /trunk/kernel/genarch/src/kbd/ Get rid of unused variable.  
3975 5587 d 7 h decky /trunk/kernel/genarch/src/drivers/ega/ keep original contents of the EGA framebuffer,
make sure the cursor is on		  
3963 5592 d 5 h jermar /trunk/kernel/ The kernel i8042 driver should be instance-neutral.  
3961 5592 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.		  
3960 5592 d 22 h jermar /trunk/kernel/genarch/include/kbd/ Remove extern declarations.  
3959 5592 d 22 h jermar /trunk/kernel/genarch/src/kbd/ Remove unneeded stuff from kernel's ns16550 driver.  
3958 5592 d 23 h jermar /trunk/kernel/genarch/src/kbd/ Do not include the IPC stuff in the i8042 kernel driver.  
3947 5593 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 5593 d 23 h jermar /trunk/kernel/ Let IRQ claim methods take irq_t * instead of the instance argument.  
3940 5594 d 3 h decky /trunk/kernel/ make hw_area API more generic
this allows mapping of EGA VRAM on ia32/amd64		  
3938 5594 d 4 h jermar /trunk/kernel/genarch/ Embed the ns16550 irq structure into the ns16550 instance structure.  
3934 5594 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 5594 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 5594 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		  
3930 5594 d 22 h jermar /trunk/kernel/ Adapt most of the kernel to ioport8_t, ioport16_t and ioport32_t types.
