3973 5592 d 23 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 5593 d 11 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
 
3964 5595 d 21 h decky /trunk/kernel/ switch between the preference of kernel/uspace IRQ hash table  
3963 5597 d 19 h jermar /trunk/kernel/ The kernel i8042 driver should be instance-neutral.  
3947 5598 d 17 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
 
3946 5598 d 17 h jermar /trunk/kernel/arch/ia32/include/ Fix ia32's pio_{read,write}_32().  
3941 5599 d 14 h jermar /trunk/kernel/ Let IRQ claim methods take irq_t * instead of the instance argument.  
3940 5599 d 17 h decky /trunk/kernel/ make hw_area API more generic
this allows mapping of EGA VRAM on ia32/amd64
 
3936 5599 d 19 h decky /trunk/ dash is not a safe character for C preprocessor, use underscore instead  
3932 5600 d 12 h jermar /trunk/kernel/ Kill arch/drivers/ega.h. Provide one-stop shopping
place for architectures with ia32 legacy I/O space.
 
3930 5600 d 13 h jermar /trunk/kernel/ Adapt most of the kernel to ioport8_t, ioport16_t and ioport32_t types.  
3929 5600 d 13 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.
 
3928 5600 d 15 h jermar /trunk/kernel/ Kill arch/drivers/i8042.h.  
3908 5603 d 16 h decky /trunk/ overhaul pareas: use one single physical area for the physical address space not belonging to physical memory  
3906 5604 d 11 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.
 
3903 5604 d 19 h jermar /trunk/kernel/arch/ia32/include/ Fix ia32 build for Pentium 3 systems.  
3902 5604 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.
 
3892 5605 d 13 h jermar /trunk/ Get rid of CONFIG_DEBUG_AS_WATCHPOINT.  
3891 5605 d 14 h jermar /trunk/ Get rid of CONFIG_SIMICS_FIX.  
3890 5605 d 14 h jermar /trunk/ Get rid of CONFIG_DEBUG_ALLREGS.
