4026 5571 d 15 h jermar /trunk/ Make the kbd port drivers platform neutral by using PIO functions.
The kernel now supplies the physical address and the kernel virtual address.		  
4023 5571 d 16 h svoboda /trunk/kernel/arch/ Unify arch_pre_main() comments.  
3982 5574 d 19 h jermar /trunk/kernel/ Do not set sysinfo for uspace drivers directly in the kernel drivers.  
3973 5576 d 2 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()		  
3971 5577 d 15 h vana /trunk/kernel/arch/ia64/src/mm/ Fix I/O access to identicaly mapped space  
3963 5580 d 22 h jermar /trunk/kernel/ The kernel i8042 driver should be instance-neutral.  
3962 5580 d 22 h jermar /trunk/kernel/arch/ia64/src/ski/ Make ia64 for ski build again.
Need to implement kernel notifications independent of IRQ notifications.		  
3941 5582 d 17 h jermar /trunk/kernel/ Let IRQ claim methods take irq_t * instead of the instance argument.  
3940 5582 d 20 h decky /trunk/kernel/ make hw_area API more generic
this allows mapping of EGA VRAM on ia32/amd64		  
3934 5583 d 14 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 5583 d 15 h jermar /trunk/kernel/ Kill arch/drivers/ega.h. Provide one-stop shopping
place for architectures with ia32 legacy I/O space.		  
3908 5586 d 19 h decky /trunk/ overhaul pareas: use one single physical area for the physical address space not belonging to physical memory  
3906 5587 d 15 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 5587 d 22 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.		  
3900 5588 d 0 h jermar /trunk/ Get rid of CONFIG_NS16550_INTERRUPT_DRIVEN and CONFIG_I8042_INTERRUPT_DRIVEN.  
3880 5590 d 18 h decky /trunk/kernel/arch/ simplify configuration
introduce arch_construct_function and inb/outb (sometimes empty) on all platforms
various code cleanup		  
3854 5601 d 6 h decky /trunk/kernel/arch/ia64/src/ski/ make compliant with r3848 (kernel/arch/mips32/src/drivers/serial.c)  
3853 5601 d 20 h jermar /trunk/kernel/arch/ia64/src/ski/ Fix ia64 build.  
3844 5602 d 16 h decky /trunk/ silent kernel console output when user space console is active  
3790 5626 d 2 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.
