4021 5572 d 4 h jermar /trunk/kernel/ There is no need to define ioport{8,16,32}_t types for each architecture separately.  
3973 5576 d 13 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()
 
3953 5582 d 4 h jermar /trunk/kernel/arch/mips32/include/ Add missing PIO functions for mips32.  
3929 5584 d 3 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 5586 d 2 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
 
3913 5586 d 11 h decky /trunk/ mips32: basic SMP support  
3908 5587 d 6 h decky /trunk/ overhaul pareas: use one single physical area for the physical address space not belonging to physical memory  
3902 5588 d 9 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 5589 d 5 h jermar /trunk/ Get rid of CONFIG_DEBUG_ALLREGS.  
3880 5591 d 5 h decky /trunk/kernel/arch/ simplify configuration
introduce arch_construct_function and inb/outb (sometimes empty) on all platforms
various code cleanup
 
3878 5591 d 5 h decky /trunk/kernel/arch/ introduce fncptr_t and ioport_t on all platforms  
3706 5649 d 6 h decky /trunk/ cstyle & small fixes  
3234 5791 d 10 h decky /trunk/ reintroduce support for MSIM text console in user space  
3233 5791 d 10 h decky /trunk/ remove dummy page coloring facility, which is currenty not used  
3230 5791 d 11 h decky /trunk/kernel/arch/mips32/ fix off-by-one bug
cleanup
 
3228 5791 d 21 h decky /trunk/ physical memory detection in MSIM (discontinous regions supported)
remove Sgi Indy (ARC) support -- it was unmaintaned, untested for years and without uspace support
 
3167 5830 d 15 h svoboda /trunk/kernel/arch/mips32/include/ Fix mips32 atomic_add() which would break build unless a constant was propagated into the second argument. (Specifically at -O0)  
3162 5832 d 3 h jermar /trunk/ The first argument to atomic_add() is read-write. (mips32)  
3134 5834 d 14 h jermar /trunk/kernel/arch/ Add smc_coherence_block().  
3133 5835 d 4 h jermar /trunk/kernel/arch/ Add smc_coherence() macro to all architectures.
So far, only amd64, ia32, ia64 and sparc64 are implemented.
