4018 5579 d 19 h decky /trunk/kernel/arch/arm32/ better inline assembler readability using the new symbolic syntax  
3973 5583 d 23 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()		  
3952 5589 d 14 h jermar /trunk/kernel/arch/arm32/ Remove unnecessary stuff from arm32.  
3951 5589 d 15 h jermar /trunk/ Unreak arm32 (as far as breakage introduced by 3947 goes) and
adapt the uspace GXemul kbd IRQ driver to use the new pseudo code.		  
3949 5589 d 15 h jermar /trunk/kernel/arch/arm32/include/ PIO functions for arm32.  
3941 5590 d 14 h jermar /trunk/kernel/ Let IRQ claim methods take irq_t * instead of the instance argument.  
3940 5590 d 17 h decky /trunk/kernel/ make hw_area API more generic
this allows mapping of EGA VRAM on ia32/amd64		  
3929 5591 d 13 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.		  
3922 5593 d 12 h decky /trunk/ make arch_pre_main optional, don't force any specific prototype
simplify boot process
mips32: detect number of configured CPUs in msim		  
3917 5593 d 13 h decky /trunk/ remove non-standard define  
3908 5594 d 16 h decky /trunk/ overhaul pareas: use one single physical area for the physical address space not belonging to physical memory  
3906 5595 d 12 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 19 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.		  
3880 5598 d 15 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 15 h decky /trunk/kernel/arch/ simplify configuration in Makefiles  
3878 5598 d 15 h decky /trunk/kernel/arch/ introduce fncptr_t and ioport_t on all platforms  
3868 5600 d 18 h jermar /trunk/kernel/arch/arm32/src/drivers/ Fix arm32 build when not configured with framebuffer.  
3844 5610 d 13 h decky /trunk/ silent kernel console output when user space console is active  
3790 5633 d 23 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.  
3789 5634 d 12 h svoboda /trunk/kernel/arch/arm32/src/ Also redraw kernel console on arm32.
