3973 5573 d 15 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 5574 d 3 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		  
3971 5575 d 4 h vana /trunk/kernel/arch/ia64/src/mm/ Fix I/O access to identicaly mapped space  
3969 5575 d 5 h jermar /trunk/ Add simple userspace FHC driver.
Modify the z8530 userspace driver
to send BUS_CLEAR_INTERRUPT
notification to the FHC driver.		  
3967 5575 d 9 h decky /trunk/kernel/arch/mips32/src/mm/ remove typo  
3966 5575 d 9 h decky /trunk/kernel/arch/mips32/src/mm/ replace old ifdefs  
3964 5576 d 13 h decky /trunk/kernel/ switch between the preference of kernel/uspace IRQ hash table  
3963 5578 d 11 h jermar /trunk/kernel/ The kernel i8042 driver should be instance-neutral.  
3962 5578 d 11 h jermar /trunk/kernel/arch/ia64/src/ski/ Make ia64 for ski build again.
Need to implement kernel notifications independent of IRQ notifications.		  
3961 5578 d 11 h jermar /trunk/ Unbreak sparc64.
Due to the lack of userspace bus drivers for the z8530 and ns16550,
we are currently handling exactly one interrupt from these devices
in userspace.		  
3957 5579 d 5 h jermar /trunk/kernel/arch/ppc32/ Unbreak ppc32 candidate.  
3956 5579 d 5 h jermar /trunk/kernel/arch/ppc32/include/ Add missing PIO functions to ppc32.  
3955 5579 d 6 h jermar /trunk/ Unbreak mips32 candidate.  
3953 5579 d 6 h jermar /trunk/kernel/arch/mips32/include/ Add missing PIO functions for mips32.  
3952 5579 d 6 h jermar /trunk/kernel/arch/arm32/ Remove unnecessary stuff from arm32.  
3951 5579 d 7 h jermar /trunk/ Unreak arm32 (as far as breakage introduced by 3947 goes) and
adapt the uspace GXemul kbd IRQ driver to use the new pseudo code.		  
3949 5579 d 7 h jermar /trunk/kernel/arch/arm32/include/ PIO functions for arm32.  
3948 5579 d 9 h jermar /trunk/kernel/arch/amd64/ Unbreak amd64.  
3947 5579 d 9 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 5579 d 9 h jermar /trunk/kernel/arch/ia32/include/ Fix ia32's pio_{read,write}_32().
