3940 5611 d 10 h decky /trunk/kernel/ make hw_area API more generic
this allows mapping of EGA VRAM on ia32/amd64
 
3929 5612 d 5 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 5615 d 9 h decky /trunk/ overhaul pareas: use one single physical area for the physical address space not belonging to physical memory  
3902 5616 d 12 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 5617 d 7 h jermar /trunk/ Get rid of CONFIG_DEBUG_ALLREGS.  
3878 5619 d 7 h decky /trunk/kernel/arch/ introduce fncptr_t and ioport_t on all platforms  
3779 5658 d 13 h jermar /trunk/kernel/ Only one kernel EGA driver to rule them all.  
3712 5677 d 6 h decky /trunk/kernel/arch/amd64/include/ synchronize drivers with ia32  
3711 5677 d 6 h decky /trunk/kernel/arch/amd64/include/ remove amd64 drivers  
3485 5749 d 6 h jermar /trunk/ Support for SYSENTER on ia32.  
3380 5784 d 8 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 5819 d 12 h decky /trunk/ remove dummy page coloring facility, which is currenty not used  
3163 5860 d 6 h jermar /trunk/ First argument to atomic functions is read-write (amd64).  
3104 5870 d 20 h svoboda /trunk/kernel/ Declare arguments for memstr.h operations as pointers instead of uintptr_t.  
3070 5873 d 12 h decky /trunk/kernel/arch/ introduce portable formatting directives
remove common types
 
3044 5874 d 7 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 5874 d 15 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 5934 d 7 h jermar /trunk/kernel/ Each architecture should only announce its endianity.
The conversion macros should be defined only once.
 
2794 5935 d 7 h jermar /trunk/kernel/ Add macros for byte swapping of uint16_t's.  
2784 5949 d 6 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.
