3973 5581 d 7 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()
 
3972 5581 d 19 h decky /trunk/kernel/ kernel memory management revisited (phase 1): proper support for zone flags
- the zone_t structures are now statically allocated to be easily available
- the locking scheme was simplified
- new flags for non-available zones were introduced
- FRAME_LOW_4_GiB flag is removed, the functionality will be eventually reimplemented using a generic mechanism
 
3968 5582 d 21 h jermar /trunk/kernel/generic/src/ddi/ Fix argument order.  
3965 5583 d 22 h svoboda /trunk/kernel/generic/src/ Fix broken doxygen syntax.  
3964 5584 d 5 h decky /trunk/kernel/ switch between the preference of kernel/uspace IRQ hash table  
3950 5586 d 23 h jermar /trunk/kernel/generic/src/ddi/ Fix UP builds.  
3947 5587 d 1 h jermar /trunk/ This is the evil commit. In particular, it does:

- introduces more powerful pseudo code for userspace IRQ top-half handlers
- changes the internals of IRQ dispatching
- simplifies the kernel's i8042 driver
- adapts the uspace i8042 driver to make use of the new pseudocode
- breaks all other architectures except ia32
- breaks almost all existing drivers
- breaks switching between uspace and kernel drivers
 
3941 5587 d 21 h jermar /trunk/kernel/ Let IRQ claim methods take irq_t * instead of the instance argument.  
3940 5588 d 1 h decky /trunk/kernel/ make hw_area API more generic
this allows mapping of EGA VRAM on ia32/amd64
 
3930 5588 d 20 h jermar /trunk/kernel/ Adapt most of the kernel to ioport8_t, ioport16_t and ioport32_t types.  
3922 5590 d 20 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
 
3920 5590 d 20 h decky /trunk/kernel/generic/include/ add min3 and max3 macros  
3919 5590 d 20 h decky /trunk/kernel/generic/include/ cstyle  
3913 5591 d 4 h decky /trunk/ mips32: basic SMP support  
3908 5592 d 0 h decky /trunk/ overhaul pareas: use one single physical area for the physical address space not belonging to physical memory  
3906 5592 d 19 h jermar /trunk/kernel/ IRQ handlers are using one superfluous argument and an unused elipsis.
On the other hand, IRQ claim functions would need to be passed the instance
argument.
 
3902 5593 d 3 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.
 
3896 5593 d 18 h svoboda /trunk/ More elegant way of invoking the loader - as a 'cloneable' service. Task names functionality lost for the time being.  
3875 5595 d 22 h decky /trunk/kernel/generic/ remove platform dependent constructs from generic code  
3870 5597 d 6 h decky /trunk/kernel/generic/src/ add includes necessary for LOG macro
