3947 5573 d 13 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		  
3946 5573 d 13 h jermar /trunk/kernel/arch/ia32/include/ Fix ia32's pio_{read,write}_32().  
3941 5574 d 9 h jermar /trunk/kernel/ Let IRQ claim methods take irq_t * instead of the instance argument.  
3940 5574 d 13 h decky /trunk/kernel/ make hw_area API more generic
this allows mapping of EGA VRAM on ia32/amd64		  
3938 5574 d 14 h jermar /trunk/kernel/genarch/ Embed the ns16550 irq structure into the ns16550 instance structure.  
3936 5574 d 15 h decky /trunk/ dash is not a safe character for C preprocessor, use underscore instead  
3935 5575 d 6 h jermar /trunk/kernel/arch/sparc64/src/drivers/ Fix sparc64 build.  
3934 5575 d 6 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 5575 d 8 h jermar /trunk/kernel/ Kill arch/drivers/ega.h. Provide one-stop shopping
place for architectures with ia32 legacy I/O space.		  
3931 5575 d 8 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 5575 d 8 h jermar /trunk/kernel/ Adapt most of the kernel to ioport8_t, ioport16_t and ioport32_t types.  
3929 5575 d 8 h jermar /trunk/kernel/arch/ Introduce ioport8_t, ioport16_t and ioport32_t. These types are to be used with
pio_read_n() and pio_write_n() functions. This breaks everything.		  
3928 5575 d 10 h jermar /trunk/kernel/ Kill arch/drivers/i8042.h.  
3927 5575 d 11 h jermar /trunk/kernel/genarch/ Nuke i8042_poll().  
3922 5577 d 8 h decky /trunk/ make arch_pre_main optional, don't force any specific prototype
simplify boot process
mips32: detect number of configured CPUs in msim		  
3920 5577 d 8 h decky /trunk/kernel/generic/include/ add min3 and max3 macros  
3919 5577 d 8 h decky /trunk/kernel/generic/include/ cstyle  
3918 5577 d 8 h decky /trunk/kernel/ avoid ugly ifdefs in fpu1 test  
3917 5577 d 8 h decky /trunk/ remove non-standard define  
3913 5577 d 16 h decky /trunk/ mips32: basic SMP support
