4022 5602 d 9 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 5602 d 9 h jermar /trunk/kernel/ There is no need to define ioport{8,16,32}_t types for each architecture separately.  
4016 5602 d 15 h decky /trunk/kernel/ better inline assembler readability using the new symbolic syntax  
4015 5602 d 17 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 5602 d 17 h decky /trunk/ cstyle  
4012 5603 d 8 h svoboda /trunk/ Task names should only contain base names of commands. Also add 'boot:' prefix for binaries loaded by the kernel.  
4011 5603 d 9 h svoboda /trunk/kernel/ String functions should be declared in string.h (and implemented in string.c) in the kernel.  
3987 5604 d 9 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 5604 d 10 h svoboda /trunk/kernel/arch/ia32/src/boot/ Rewrite rest of multiboot info parsing to C.  
3984 5604 d 10 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 5605 d 11 h jermar /trunk/kernel/ Do not set sysinfo for uspace drivers directly in the kernel drivers.  
3973 5606 d 18 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 5607 d 6 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 5609 d 16 h decky /trunk/kernel/ switch between the preference of kernel/uspace IRQ hash table  
3963 5611 d 14 h jermar /trunk/kernel/ The kernel i8042 driver should be instance-neutral.  
3947 5612 d 12 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 5612 d 13 h jermar /trunk/kernel/arch/ia32/include/ Fix ia32's pio_{read,write}_32().  
3941 5613 d 9 h jermar /trunk/kernel/ Let IRQ claim methods take irq_t * instead of the instance argument.  
3940 5613 d 13 h decky /trunk/kernel/ make hw_area API more generic
this allows mapping of EGA VRAM on ia32/amd64
 
3936 5613 d 14 h decky /trunk/ dash is not a safe character for C preprocessor, use underscore instead  
3932 5614 d 8 h jermar /trunk/kernel/ Kill arch/drivers/ega.h. Provide one-stop shopping
place for architectures with ia32 legacy I/O space.
 
3930 5614 d 8 h jermar /trunk/kernel/ Adapt most of the kernel to ioport8_t, ioport16_t and ioport32_t types.  
3929 5614 d 8 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 5614 d 10 h jermar /trunk/kernel/ Kill arch/drivers/i8042.h.  
3908 5617 d 11 h decky /trunk/ overhaul pareas: use one single physical area for the physical address space not belonging to physical memory  
3906 5618 d 7 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 5618 d 14 h jermar /trunk/kernel/arch/ia32/include/ Fix ia32 build for Pentium 3 systems.  
3902 5618 d 14 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 5619 d 9 h jermar /trunk/ Get rid of CONFIG_DEBUG_AS_WATCHPOINT.  
3891 5619 d 9 h jermar /trunk/ Get rid of CONFIG_SIMICS_FIX.  
3890 5619 d 10 h jermar /trunk/ Get rid of CONFIG_DEBUG_ALLREGS.  
3889 5619 d 15 h svoboda /trunk/kernel/arch/ia32/include/drivers/ Make ia32/amd64 compile again. This is mostly a hack, but a more drastic cleanup is needed to do it the right way.  
3880 5621 d 10 h decky /trunk/kernel/arch/ simplify configuration
introduce arch_construct_function and inb/outb (sometimes empty) on all platforms
various code cleanup
 
3879 5621 d 10 h decky /trunk/kernel/arch/ simplify configuration in Makefiles  
3878 5621 d 10 h decky /trunk/kernel/arch/ introduce fncptr_t and ioport_t on all platforms  
3802 5645 d 14 h decky /trunk/kernel/arch/ fallback to VGA registers if VESA routine fails  
3800 5646 d 9 h decky /trunk/kernel/arch/ simplify compile options  
3790 5656 d 18 h svoboda /trunk/kernel/ Make newlines in panic messages consistent. Add periods at end of messages so that it is obvious whether they are printed entirely.  
3788 5657 d 7 h svoboda /trunk/kernel/ Unify newlines in fault_if_from_uspace() format strings. (Remove them and print newline automatically). Also start messages with caps.  
3779 5660 d 16 h jermar /trunk/kernel/ Only one kernel EGA driver to rule them all.
