3902 5638 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.
 
3880 5641 d 1 h decky /trunk/kernel/arch/ simplify configuration
introduce arch_construct_function and inb/outb (sometimes empty) on all platforms
various code cleanup
 
3878 5641 d 1 h decky /trunk/kernel/arch/ introduce fncptr_t and ioport_t on all platforms  
3779 5680 d 7 h jermar /trunk/kernel/ Only one kernel EGA driver to rule them all.  
3740 5690 d 5 h jermar /trunk/kernel/arch/sparc64/ Fix typo.  
3736 5691 d 7 h decky /trunk/kernel/arch/sparc64/ refresh kernel console during grab on sparc64  
3722 5695 d 11 h rimsky /trunk/kernel/arch/sparc64/include/ SMC functions optimized for US3.  
3672 5710 d 1 h jermar /trunk/ Merge sparc branch to trunk.  
3655 5716 d 1 h jermar /trunk/kernel/ Add additional members to the irq_t structure so that an interrupt-driven driver
does not need to know how to clear the level interrupt. The z8530 was modified
in this way and is much more generic. The ns16550 driver has also been modified,
but awaits testing. The sparc64 interrupt mapping and dispatch code is now using
the new info and calls the clear-interrupt-routine itself.
 
3654 5716 d 3 h jermar /trunk/kernel/arch/sparc64/ After my effort yesterday, there are two rival psycho drivers.
Merge the two and remove the newer one.
 
3647 5717 d 0 h jermar /trunk/kernel/arch/sparc64/ Improvized Psycho driver.  
3580 5733 d 23 h jermar /trunk/kernel/arch/sparc64/include/ Accesses to memory mapped registers should use volatile pointers so that
the compiler doesn't even think of trying to be clever. Add memory barriers
and fixed cstyle.
 
3577 5734 d 13 h vana /trunk/kernel/ Support for serial port console on IA64 as a compensation for keyboard - based on SPARC ns16550 driver  
3482 5774 d 1 h jermar /trunk/kernel/arch/sparc64/ Do not allocate full page for the uspace window buffer.
Instead, allocate only the bare minimum to fit NWINDOWS - 1
uspace windows and to satisfy alignment requirements.
 
3463 5786 d 6 h jermar /trunk/kernel/arch/sparc64/ Populate all sparc64 trap table slots belonging to trap_instruction_n.  
3379 5806 d 12 h jermar /trunk/kernel/arch/sparc64/include/ Add the missing preemption_disable() call to sparc64 atomic_lock_arch().
Thanks to Pavel Rimsky for noticing this.
 
3233 5841 d 6 h decky /trunk/ remove dummy page coloring facility, which is currenty not used  
3145 5883 d 13 h jermar /trunk/kernel/arch/sparc64/include/ On sparc64, when the operand to the FLUSH instruction doesn't matter, the
instruction's semantics is to flush the pipeline.
 
3134 5884 d 11 h jermar /trunk/kernel/arch/ Add smc_coherence_block().  
3133 5885 d 0 h jermar /trunk/kernel/arch/ Add smc_coherence() macro to all architectures.
So far, only amd64, ia32, ia64 and sparc64 are implemented.
