4015 5694 d 0 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 5694 d 0 h decky /trunk/ cstyle  
4012 5694 d 14 h svoboda /trunk/ Task names should only contain base names of commands. Also add 'boot:' prefix for binaries loaded by the kernel.  
4011 5694 d 15 h svoboda /trunk/kernel/ String functions should be declared in string.h (and implemented in string.c) in the kernel.  
3987 5695 d 16 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 5695 d 17 h svoboda /trunk/kernel/arch/ia32/src/boot/ Rewrite rest of multiboot info parsing to C.  
3984 5695 d 17 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 5696 d 18 h jermar /trunk/kernel/ Do not set sysinfo for uspace drivers directly in the kernel drivers.  
3978 5697 d 16 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 5698 d 1 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 5698 d 13 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 5699 d 13 h vana /trunk/kernel/arch/ia64/src/mm/ Fix I/O access to identicaly mapped space  
3969 5699 d 15 h jermar /trunk/ Add simple userspace FHC driver.
Modify the z8530 userspace driver
to send BUS_CLEAR_INTERRUPT
notification to the FHC driver.		  
3967 5699 d 19 h decky /trunk/kernel/arch/mips32/src/mm/ remove typo  
3966 5699 d 19 h decky /trunk/kernel/arch/mips32/src/mm/ replace old ifdefs  
3964 5700 d 23 h decky /trunk/kernel/ switch between the preference of kernel/uspace IRQ hash table  
3963 5702 d 21 h jermar /trunk/kernel/ The kernel i8042 driver should be instance-neutral.  
3962 5702 d 21 h jermar /trunk/kernel/arch/ia64/src/ski/ Make ia64 for ski build again.
Need to implement kernel notifications independent of IRQ notifications.		  
3961 5702 d 21 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 5703 d 15 h jermar /trunk/kernel/arch/ppc32/ Unbreak ppc32 candidate.  
3956 5703 d 15 h jermar /trunk/kernel/arch/ppc32/include/ Add missing PIO functions to ppc32.  
3955 5703 d 16 h jermar /trunk/ Unbreak mips32 candidate.  
3953 5703 d 16 h jermar /trunk/kernel/arch/mips32/include/ Add missing PIO functions for mips32.  
3952 5703 d 16 h jermar /trunk/kernel/arch/arm32/ Remove unnecessary stuff from arm32.  
3951 5703 d 17 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 5703 d 17 h jermar /trunk/kernel/arch/arm32/include/ PIO functions for arm32.  
3948 5703 d 19 h jermar /trunk/kernel/arch/amd64/ Unbreak amd64.  
3947 5703 d 19 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 5703 d 19 h jermar /trunk/kernel/arch/ia32/include/ Fix ia32's pio_{read,write}_32().  
3941 5704 d 16 h jermar /trunk/kernel/ Let IRQ claim methods take irq_t * instead of the instance argument.  
3940 5704 d 19 h decky /trunk/kernel/ make hw_area API more generic
this allows mapping of EGA VRAM on ia32/amd64		  
3936 5704 d 21 h decky /trunk/ dash is not a safe character for C preprocessor, use underscore instead  
3935 5705 d 12 h jermar /trunk/kernel/arch/sparc64/src/drivers/ Fix sparc64 build.  
3934 5705 d 13 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 5705 d 14 h jermar /trunk/kernel/ Kill arch/drivers/ega.h. Provide one-stop shopping
place for architectures with ia32 legacy I/O space.		  
3930 5705 d 15 h jermar /trunk/kernel/ Adapt most of the kernel to ioport8_t, ioport16_t and ioport32_t types.  
3929 5705 d 15 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 5705 d 17 h jermar /trunk/kernel/ Kill arch/drivers/i8042.h.  
3922 5707 d 14 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		  
3917 5707 d 15 h decky /trunk/ remove non-standard define
