3973 5729 d 15 h decky /trunk/kernel/ kernel memory management revisited (phase 2): map physical memory according to zones
- ia32: register reserved and ACPI zones
- pareas are now used only for mapping of present physical memory (hw_area() is gone)
- firmware zones and physical addresses outside any zones are allowed to be mapped generally
- fix nasty antient bug in zones_insert_zone()		  
3963 5734 d 10 h jermar /trunk/kernel/ The kernel i8042 driver should be instance-neutral.  
3948 5735 d 8 h jermar /trunk/kernel/arch/amd64/ Unbreak amd64.  
3940 5736 d 9 h decky /trunk/kernel/ make hw_area API more generic
this allows mapping of EGA VRAM on ia32/amd64		  
3932 5737 d 4 h jermar /trunk/kernel/ Kill arch/drivers/ega.h. Provide one-stop shopping
place for architectures with ia32 legacy I/O space.		  
3929 5737 d 4 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.		  
3908 5740 d 7 h decky /trunk/ overhaul pareas: use one single physical area for the physical address space not belonging to physical memory  
3906 5741 d 3 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 5741 d 11 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 5742 d 5 h jermar /trunk/ Get rid of CONFIG_DEBUG_AS_WATCHPOINT.  
3890 5742 d 6 h jermar /trunk/ Get rid of CONFIG_DEBUG_ALLREGS.  
3880 5744 d 6 h decky /trunk/kernel/arch/ simplify configuration
introduce arch_construct_function and inb/outb (sometimes empty) on all platforms
various code cleanup		  
3879 5744 d 6 h decky /trunk/kernel/arch/ simplify configuration in Makefiles  
3878 5744 d 6 h decky /trunk/kernel/arch/ introduce fncptr_t and ioport_t on all platforms  
3851 5755 d 9 h jermar /trunk/kernel/arch/amd64/src/ Fix amd64 UP build.  
3838 5756 d 13 h decky /trunk/kernel/ make RANDI a generic macro  
3802 5768 d 11 h decky /trunk/kernel/arch/ fallback to VGA registers if VESA routine fails  
3790 5779 d 14 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 5780 d 3 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 5783 d 12 h jermar /trunk/kernel/ Only one kernel EGA driver to rule them all.
