3963 5613 d 7 h jermar /trunk/kernel/ The kernel i8042 driver should be instance-neutral.  
3947 5614 d 5 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 5615 d 2 h jermar /trunk/kernel/ Let IRQ claim methods take irq_t * instead of the instance argument.  
3940 5615 d 6 h decky /trunk/kernel/ make hw_area API more generic
this allows mapping of EGA VRAM on ia32/amd64		  
3932 5616 d 1 h jermar /trunk/kernel/ Kill arch/drivers/ega.h. Provide one-stop shopping
place for architectures with ia32 legacy I/O space.		  
3930 5616 d 1 h jermar /trunk/kernel/ Adapt most of the kernel to ioport8_t, ioport16_t and ioport32_t types.  
3908 5619 d 4 h decky /trunk/ overhaul pareas: use one single physical area for the physical address space not belonging to physical memory  
3906 5620 d 0 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.		  
3902 5620 d 7 h jermar /trunk/kernel/ Introduce a more platform-neutral name for programmed I/O.

The new API looks like pio_read_n() or pio_write_n(), where n is 8, 16 or 32.
The old API (i.e. inb(), inw(), inl(), outb() outw(), outl()) may have made
some people think that the interface is only to be used with the separate I/O
space. That's not the case. This API is to be implemented on all platforms
so that we can finally have really generic kernel device drivers.		  
3892 5621 d 2 h jermar /trunk/ Get rid of CONFIG_DEBUG_AS_WATCHPOINT.  
3891 5621 d 2 h jermar /trunk/ Get rid of CONFIG_SIMICS_FIX.  
3890 5621 d 3 h jermar /trunk/ Get rid of CONFIG_DEBUG_ALLREGS.  
3880 5623 d 3 h decky /trunk/kernel/arch/ simplify configuration
introduce arch_construct_function and inb/outb (sometimes empty) on all platforms
various code cleanup		  
3802 5647 d 7 h decky /trunk/kernel/arch/ fallback to VGA registers if VESA routine fails  
3790 5658 d 11 h svoboda /trunk/kernel/ Make newlines in panic messages consistent. Add periods at end of messages so that it is obvious whether they are printed entirely.  
3788 5659 d 0 h svoboda /trunk/kernel/ Unify newlines in fault_if_from_uspace() format strings. (Remove them and print newline automatically). Also start messages with caps.  
3779 5662 d 9 h jermar /trunk/kernel/ Only one kernel EGA driver to rule them all.  
3751 5670 d 11 h svoboda /trunk/kernel/arch/ia32/src/drivers/ Revive kernel EGA fb driver. Plus fix bug -- was using memcpy() for scrolling instead of memmove().  
3709 5681 d 4 h decky /trunk/kernel/ invert VGA 3:2:3 palette to reflect changes in revision 3692  
3707 5681 d 4 h decky /trunk/ kconsole is optional
kernel & uspace framebuffer rewrite with speedups (some things are slightly broken yet)
