3961 5599 d 1 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.		  
3957 5599 d 19 h jermar /trunk/kernel/arch/ppc32/ Unbreak ppc32 candidate.  
3956 5599 d 19 h jermar /trunk/kernel/arch/ppc32/include/ Add missing PIO functions to ppc32.  
3955 5599 d 19 h jermar /trunk/ Unbreak mips32 candidate.  
3953 5599 d 20 h jermar /trunk/kernel/arch/mips32/include/ Add missing PIO functions for mips32.  
3952 5599 d 20 h jermar /trunk/kernel/arch/arm32/ Remove unnecessary stuff from arm32.  
3951 5599 d 21 h jermar /trunk/ Unreak arm32 (as far as breakage introduced by 3947 goes) and
adapt the uspace GXemul kbd IRQ driver to use the new pseudo code.		  
3949 5599 d 21 h jermar /trunk/kernel/arch/arm32/include/ PIO functions for arm32.  
3948 5599 d 22 h jermar /trunk/kernel/arch/amd64/ Unbreak amd64.  
3947 5599 d 23 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 5599 d 23 h jermar /trunk/kernel/arch/ia32/include/ Fix ia32's pio_{read,write}_32().  
3941 5600 d 19 h jermar /trunk/kernel/ Let IRQ claim methods take irq_t * instead of the instance argument.  
3940 5600 d 23 h decky /trunk/kernel/ make hw_area API more generic
this allows mapping of EGA VRAM on ia32/amd64		  
3936 5601 d 0 h decky /trunk/ dash is not a safe character for C preprocessor, use underscore instead  
3935 5601 d 16 h jermar /trunk/kernel/arch/sparc64/src/drivers/ Fix sparc64 build.  
3934 5601 d 16 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 5601 d 18 h jermar /trunk/kernel/ Kill arch/drivers/ega.h. Provide one-stop shopping
place for architectures with ia32 legacy I/O space.		  
3930 5601 d 18 h jermar /trunk/kernel/ Adapt most of the kernel to ioport8_t, ioport16_t and ioport32_t types.  
3929 5601 d 18 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 5601 d 20 h jermar /trunk/kernel/ Kill arch/drivers/i8042.h.
