4022 5604 d 22 h svoboda /trunk/ Move multiboot parsing to genarch/*/multiboot and adapt it for use with both ia32 and amd64. Multiboot info parsing now supported on amd64, too.  
4021 5604 d 23 h jermar /trunk/kernel/ There is no need to define ioport{8,16,32}_t types for each architecture separately.  
4018 5605 d 3 h decky /trunk/kernel/arch/arm32/ better inline assembler readability using the new symbolic syntax  
4017 5605 d 4 h decky /trunk/kernel/arch/amd64/ better inline assembler readability using the new symbolic syntax  
4016 5605 d 4 h decky /trunk/kernel/ better inline assembler readability using the new symbolic syntax  
4015 5605 d 7 h decky /trunk/kernel/arch/ia32/ rename ia32_cboot() to arch_pre_main() and move it to ia32.c (to be in line with other platforms)  
4014 5605 d 7 h decky /trunk/ cstyle  
4012 5605 d 21 h svoboda /trunk/ Task names should only contain base names of commands. Also add 'boot:' prefix for binaries loaded by the kernel.  
4011 5605 d 22 h svoboda /trunk/kernel/ String functions should be declared in string.h (and implemented in string.c) in the kernel.  
3987 5606 d 23 h svoboda /trunk/kernel/ Read command line for multiboot modules on ia32 and copy it to task name. Other arches will need to initialize task names in the init structure to an empty string.  
3985 5607 d 0 h svoboda /trunk/kernel/arch/ia32/src/boot/ Rewrite rest of multiboot info parsing to C.  
3984 5607 d 0 h svoboda /trunk/kernel/ The ia32-specific boot code is written completely in assembly for no reason. Start fixing this. For now rewrite the copying of multiboot info to C.  
3982 5608 d 1 h jermar /trunk/kernel/ Do not set sysinfo for uspace drivers directly in the kernel drivers.  
3978 5608 d 23 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.		  
3973 5609 d 8 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 5609 d 20 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 5610 d 21 h vana /trunk/kernel/arch/ia64/src/mm/ Fix I/O access to identicaly mapped space  
3969 5610 d 22 h jermar /trunk/ Add simple userspace FHC driver.
Modify the z8530 userspace driver
to send BUS_CLEAR_INTERRUPT
notification to the FHC driver.		  
3967 5611 d 2 h decky /trunk/kernel/arch/mips32/src/mm/ remove typo  
3966 5611 d 2 h decky /trunk/kernel/arch/mips32/src/mm/ replace old ifdefs  
3964 5612 d 6 h decky /trunk/kernel/ switch between the preference of kernel/uspace IRQ hash table  
3963 5614 d 4 h jermar /trunk/kernel/ The kernel i8042 driver should be instance-neutral.  
3962 5614 d 4 h jermar /trunk/kernel/arch/ia64/src/ski/ Make ia64 for ski build again.
Need to implement kernel notifications independent of IRQ notifications.		  
3961 5614 d 4 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 5614 d 22 h jermar /trunk/kernel/arch/ppc32/ Unbreak ppc32 candidate.  
3956 5614 d 22 h jermar /trunk/kernel/arch/ppc32/include/ Add missing PIO functions to ppc32.  
3955 5614 d 23 h jermar /trunk/ Unbreak mips32 candidate.  
3953 5614 d 23 h jermar /trunk/kernel/arch/mips32/include/ Add missing PIO functions for mips32.  
3952 5614 d 23 h jermar /trunk/kernel/arch/arm32/ Remove unnecessary stuff from arm32.  
3951 5615 d 0 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 5615 d 0 h jermar /trunk/kernel/arch/arm32/include/ PIO functions for arm32.  
3948 5615 d 2 h jermar /trunk/kernel/arch/amd64/ Unbreak amd64.  
3947 5615 d 2 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 5615 d 3 h jermar /trunk/kernel/arch/ia32/include/ Fix ia32's pio_{read,write}_32().  
3941 5615 d 23 h jermar /trunk/kernel/ Let IRQ claim methods take irq_t * instead of the instance argument.  
3940 5616 d 2 h decky /trunk/kernel/ make hw_area API more generic
this allows mapping of EGA VRAM on ia32/amd64		  
3936 5616 d 4 h decky /trunk/ dash is not a safe character for C preprocessor, use underscore instead  
3935 5616 d 20 h jermar /trunk/kernel/arch/sparc64/src/drivers/ Fix sparc64 build.  
3934 5616 d 20 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 5616 d 21 h jermar /trunk/kernel/ Kill arch/drivers/ega.h. Provide one-stop shopping
place for architectures with ia32 legacy I/O space.
