3978 5600 d 7 h jermar /trunk/ Userspace driver for OBIO. This will make it possible to clear interrupts from
user space on UltraSPARC IIi and systems with Psycho. Not tested.		  
3975 5600 d 14 h decky /trunk/kernel/genarch/src/drivers/ega/ keep original contents of the EGA framebuffer,
make sure the cursor is on		  
3974 5600 d 14 h decky /trunk/kernel/generic/src/console/ prettyprint help and tests  
3973 5600 d 16 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 5601 d 4 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 5602 d 4 h vana /trunk/kernel/arch/ia64/src/mm/ Fix I/O access to identicaly mapped space  
3969 5602 d 6 h jermar /trunk/ Add simple userspace FHC driver.
Modify the z8530 userspace driver
to send BUS_CLEAR_INTERRUPT
notification to the FHC driver.		  
3968 5602 d 6 h jermar /trunk/kernel/generic/src/ddi/ Fix argument order.  
3967 5602 d 10 h decky /trunk/kernel/arch/mips32/src/mm/ remove typo  
3966 5602 d 10 h decky /trunk/kernel/arch/mips32/src/mm/ replace old ifdefs  
3965 5603 d 7 h svoboda /trunk/kernel/generic/src/ Fix broken doxygen syntax.  
3964 5603 d 14 h decky /trunk/kernel/ switch between the preference of kernel/uspace IRQ hash table  
3963 5605 d 11 h jermar /trunk/kernel/ The kernel i8042 driver should be instance-neutral.  
3962 5605 d 12 h jermar /trunk/kernel/arch/ia64/src/ski/ Make ia64 for ski build again.
Need to implement kernel notifications independent of IRQ notifications.		  
3961 5605 d 12 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.		  
3960 5606 d 5 h jermar /trunk/kernel/genarch/include/kbd/ Remove extern declarations.  
3959 5606 d 5 h jermar /trunk/kernel/genarch/src/kbd/ Remove unneeded stuff from kernel's ns16550 driver.  
3958 5606 d 5 h jermar /trunk/kernel/genarch/src/kbd/ Do not include the IPC stuff in the i8042 kernel driver.  
3957 5606 d 6 h jermar /trunk/kernel/arch/ppc32/ Unbreak ppc32 candidate.  
3956 5606 d 6 h jermar /trunk/kernel/arch/ppc32/include/ Add missing PIO functions to ppc32.  
3955 5606 d 6 h jermar /trunk/ Unbreak mips32 candidate.  
3953 5606 d 7 h jermar /trunk/kernel/arch/mips32/include/ Add missing PIO functions for mips32.  
3952 5606 d 7 h jermar /trunk/kernel/arch/arm32/ Remove unnecessary stuff from arm32.  
3951 5606 d 8 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.		  
3950 5606 d 8 h jermar /trunk/kernel/generic/src/ddi/ Fix UP builds.  
3949 5606 d 8 h jermar /trunk/kernel/arch/arm32/include/ PIO functions for arm32.  
3948 5606 d 9 h jermar /trunk/kernel/arch/amd64/ Unbreak amd64.  
3947 5606 d 10 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 5606 d 10 h jermar /trunk/kernel/arch/ia32/include/ Fix ia32's pio_{read,write}_32().  
3941 5607 d 6 h jermar /trunk/kernel/ Let IRQ claim methods take irq_t * instead of the instance argument.  
3940 5607 d 10 h decky /trunk/kernel/ make hw_area API more generic
this allows mapping of EGA VRAM on ia32/amd64		  
3938 5607 d 11 h jermar /trunk/kernel/genarch/ Embed the ns16550 irq structure into the ns16550 instance structure.  
3936 5607 d 11 h decky /trunk/ dash is not a safe character for C preprocessor, use underscore instead  
3935 5608 d 3 h jermar /trunk/kernel/arch/sparc64/src/drivers/ Fix sparc64 build.  
3934 5608 d 3 h jermar /trunk/kernel/ Improve the ns16550 driver.

- The driver support multiple instances.
- It still remembers the last registered IRQ in a global structure (cannot be
easily fixed now)
- Was converted to use PIO directly		  
3932 5608 d 5 h jermar /trunk/kernel/ Kill arch/drivers/ega.h. Provide one-stop shopping
place for architectures with ia32 legacy I/O space.		  
3931 5608 d 5 h jermar /trunk/kernel/genarch/ Improve the i8042 kernel driver (phase I).

- Convert the code to be instance-aware
- Still using hardcoded initialization from legacy IO address
- Use elegant i8042 register map for PIO		  
3930 5608 d 5 h jermar /trunk/kernel/ Adapt most of the kernel to ioport8_t, ioport16_t and ioport32_t types.  
3929 5608 d 5 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 5608 d 7 h jermar /trunk/kernel/ Kill arch/drivers/i8042.h.
