4017 5579 d 20 h decky /trunk/kernel/arch/amd64/ better inline assembler readability using the new symbolic syntax  
3987 5581 d 15 h svoboda /trunk/kernel/ Read command line for multiboot modules on ia32 and copy it to task name. Other arches will need to initialize task names in the init structure to an empty string.  
3982 5582 d 17 h jermar /trunk/kernel/ Do not set sysinfo for uspace drivers directly in the kernel drivers.  
3973 5584 d 0 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 5588 d 20 h jermar /trunk/kernel/ The kernel i8042 driver should be instance-neutral.  
3948 5589 d 18 h jermar /trunk/kernel/arch/amd64/ Unbreak amd64.  
3940 5590 d 19 h decky /trunk/kernel/ make hw_area API more generic
this allows mapping of EGA VRAM on ia32/amd64		  
3932 5591 d 14 h jermar /trunk/kernel/ Kill arch/drivers/ega.h. Provide one-stop shopping
place for architectures with ia32 legacy I/O space.		  
3929 5591 d 14 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 5594 d 17 h decky /trunk/ overhaul pareas: use one single physical area for the physical address space not belonging to physical memory  
3906 5595 d 13 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 5595 d 21 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 5596 d 15 h jermar /trunk/ Get rid of CONFIG_DEBUG_AS_WATCHPOINT.  
3890 5596 d 16 h jermar /trunk/ Get rid of CONFIG_DEBUG_ALLREGS.  
3880 5598 d 16 h decky /trunk/kernel/arch/ simplify configuration
introduce arch_construct_function and inb/outb (sometimes empty) on all platforms
various code cleanup		  
3879 5598 d 16 h decky /trunk/kernel/arch/ simplify configuration in Makefiles  
3878 5598 d 16 h decky /trunk/kernel/arch/ introduce fncptr_t and ioport_t on all platforms  
3851 5609 d 18 h jermar /trunk/kernel/arch/amd64/src/ Fix amd64 UP build.  
3838 5610 d 23 h decky /trunk/kernel/ make RANDI a generic macro  
3802 5622 d 20 h decky /trunk/kernel/arch/ fallback to VGA registers if VESA routine fails
