4148 5586 d 21 h decky /trunk/ as kernel little brother drivers are not needed anymore, the device numbers do not have to be correlated between kernel and uspace in any way
introduce new syscall sys_device_assign_devno() for generating system-wide unique device numbers for uspace
 
4030 5600 d 9 h svoboda /trunk/ Init-task names for ppc32.  
4021 5601 d 11 h jermar /trunk/kernel/ There is no need to define ioport{8,16,32}_t types for each architecture separately.  
3973 5605 d 20 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()
 
3957 5611 d 10 h jermar /trunk/kernel/arch/ppc32/ Unbreak ppc32 candidate.  
3956 5611 d 10 h jermar /trunk/kernel/arch/ppc32/include/ Add missing PIO functions to ppc32.  
3929 5613 d 10 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 5615 d 9 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
 
3908 5616 d 13 h decky /trunk/ overhaul pareas: use one single physical area for the physical address space not belonging to physical memory  
3902 5617 d 16 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 5620 d 11 h decky /trunk/kernel/arch/ simplify configuration
introduce arch_construct_function and inb/outb (sometimes empty) on all platforms
various code cleanup
 
3878 5620 d 11 h decky /trunk/kernel/arch/ introduce fncptr_t and ioport_t on all platforms  
3857 5630 d 13 h decky /trunk/ very experimental TLB refill for ppc32  
3856 5630 d 15 h decky /trunk/ ppc32: strict coherency, compatible TLB flush  
3837 5632 d 18 h decky /trunk/kernel/arch/ppc32/ use pseudorandom generator to avoid even the longest path of livelock collisions  
3833 5633 d 15 h decky /trunk/ avoid nasty race condition during page fault handling  
3830 5634 d 13 h decky /trunk/kernel/arch/ppc32/ ppc32: add support for cache disable page access control  
3829 5634 d 14 h decky /trunk/ use macio optionally  
3406 5771 d 20 h svoboda /trunk/kernel/arch/ppc32/include/ Merge changeset 3114 from tracing into trunk. (implementation of istate_from_uspace() for ppc32)  
3233 5820 d 16 h decky /trunk/ remove dummy page coloring facility, which is currenty not used
