3940 5607 d 13 h decky /trunk/kernel/ make hw_area API more generic
this allows mapping of EGA VRAM on ia32/amd64
 
3938 5607 d 14 h jermar /trunk/kernel/genarch/ Embed the ns16550 irq structure into the ns16550 instance structure.  
3934 5608 d 7 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 5608 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 5608 d 9 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 5608 d 9 h jermar /trunk/kernel/ Adapt most of the kernel to ioport8_t, ioport16_t and ioport32_t types.  
3928 5608 d 11 h jermar /trunk/kernel/ Kill arch/drivers/i8042.h.  
3927 5608 d 11 h jermar /trunk/kernel/genarch/ Nuke i8042_poll().  
3908 5611 d 12 h decky /trunk/ overhaul pareas: use one single physical area for the physical address space not belonging to physical memory  
3906 5612 d 8 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 5612 d 15 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 5612 d 17 h jermar /trunk/ Get rid of CONFIG_NS16550_INTERRUPT_DRIVEN and CONFIG_I8042_INTERRUPT_DRIVEN.  
3877 5615 d 11 h decky /trunk/kernel/genarch/ remove (almost all) platform dependent code from drivers  
3876 5615 d 11 h decky /trunk/kernel/genarch/ add BGR 888 visual, remove FB_INVERT_ENDIAN  
3844 5627 d 9 h decky /trunk/ silent kernel console output when user space console is active  
3790 5650 d 19 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.  
3779 5654 d 17 h jermar /trunk/kernel/ Only one kernel EGA driver to rule them all.  
3752 5662 d 19 h svoboda /trunk/kernel/genarch/src/fb/ Another memmove() instead of memcpy().  
3741 5664 d 14 h jermar /trunk/kernel/genarch/src/fb/ cstyle  
3733 5665 d 17 h decky /trunk/kernel/genarch/src/fb/ fix console overdrawing when is logo on
