3973 5595 d 10 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()		  
3948 5601 d 3 h jermar /trunk/kernel/arch/amd64/ Unbreak amd64.  
3940 5602 d 4 h decky /trunk/kernel/ make hw_area API more generic
this allows mapping of EGA VRAM on ia32/amd64		  
3929 5602 d 23 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 5606 d 2 h decky /trunk/ overhaul pareas: use one single physical area for the physical address space not belonging to physical memory  
3902 5607 d 6 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.		  
3890 5608 d 1 h jermar /trunk/ Get rid of CONFIG_DEBUG_ALLREGS.  
3878 5610 d 1 h decky /trunk/kernel/arch/ introduce fncptr_t and ioport_t on all platforms  
3779 5649 d 7 h jermar /trunk/kernel/ Only one kernel EGA driver to rule them all.  
3712 5667 d 23 h decky /trunk/kernel/arch/amd64/include/ synchronize drivers with ia32  
3711 5667 d 23 h decky /trunk/kernel/arch/amd64/include/ remove amd64 drivers  
3485 5740 d 0 h jermar /trunk/ Support for SYSENTER on ia32.  
3380 5775 d 1 h jermar /trunk/kernel/arch/amd64/include/ Prevent 'tmp' in amd64's atomic_lock_arch() from being allocated
to the same register as 'val->count'.		  
3233 5810 d 6 h decky /trunk/ remove dummy page coloring facility, which is currenty not used  
3163 5851 d 0 h jermar /trunk/ First argument to atomic functions is read-write (amd64).  
3104 5861 d 14 h svoboda /trunk/kernel/ Declare arguments for memstr.h operations as pointers instead of uintptr_t.  
3070 5864 d 6 h decky /trunk/kernel/arch/ introduce portable formatting directives
remove common types		  
3044 5865 d 0 h jermar /trunk/kernel/arch/amd64/ Some inline functions in memstr.h seem to be of uncertain origin (amd64).
Replace either with built-in functions or with generic functions.		  
3040 5865 d 9 h svoboda /trunk/kernel/arch/amd64/include/ Fix register-constraint typo in amd64 memstr.h and add two '&'s for symmetry's sake. (None were really causing trouble)  
2797 5925 d 1 h jermar /trunk/kernel/ Each architecture should only announce its endianity.
The conversion macros should be defined only once.
