3902 5706 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.
 
3890 5707 d 14 h jermar /trunk/ Get rid of CONFIG_DEBUG_ALLREGS.  
3878 5709 d 14 h decky /trunk/kernel/arch/ introduce fncptr_t and ioport_t on all platforms  
3779 5748 d 20 h jermar /trunk/kernel/ Only one kernel EGA driver to rule them all.  
3712 5767 d 12 h decky /trunk/kernel/arch/amd64/include/ synchronize drivers with ia32  
3711 5767 d 12 h decky /trunk/kernel/arch/amd64/include/ remove amd64 drivers  
3485 5839 d 13 h jermar /trunk/ Support for SYSENTER on ia32.  
3380 5874 d 14 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 5909 d 19 h decky /trunk/ remove dummy page coloring facility, which is currenty not used  
3163 5950 d 13 h jermar /trunk/ First argument to atomic functions is read-write (amd64).  
3104 5961 d 3 h svoboda /trunk/kernel/ Declare arguments for memstr.h operations as pointers instead of uintptr_t.  
3070 5963 d 19 h decky /trunk/kernel/arch/ introduce portable formatting directives
remove common types
 
3044 5964 d 13 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 5964 d 21 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 6024 d 14 h jermar /trunk/kernel/ Each architecture should only announce its endianity.
The conversion macros should be defined only once.
 
2794 6025 d 14 h jermar /trunk/kernel/ Add macros for byte swapping of uint16_t's.  
2784 6039 d 13 h jermar /trunk/kernel/arch/ Fortify ia32 and amd64 kernels against mallicious uspace applications that set
DF prior to entering the kernel. For AMD64 syscalls, we don't use the CLD
instruction, but make use of the SFMASK MSR instead. Simics works fine with
it, but QEMU seems to have a problem.
 
2777 6044 d 0 h cejka /trunk/ Unified context handling code for amd64.  
2774 6044 d 1 h cejka /trunk/kernel/arch/ Context.s renamed to context.S for ia32 and fixed links for ia32xen.
Added asm macros for context save/restore and offset definitions.
 
2725 6081 d 20 h decky /trunk/kernel/ remove config.memory_size, get_memory_size() and memory_init.{c|d}
the amount of available memory can be calculated from the sizes of the zones
add FRAMES2SIZE, SIZE2KB and SIZE2MB functions/macros (code readability)
