4126 5618 d 2 h decky /trunk/kernel/arch/ cleanup pm.h and related stuff (no change in functionality)  
4125 5618 d 3 h decky /trunk/kernel/arch/ia32/ rename selector() to gdtselector() to unify with amd64  
4099 5618 d 21 h decky /trunk/kernel/arch/ia32/src/ update for the new scheme of wiring device drivers to keyboard/serial modules
use ega_redraw() only if it is compiled in
 
4098 5618 d 21 h decky /trunk/kernel/arch/ia32/include/drivers/ whitespace changes  
4097 5618 d 21 h decky /trunk/kernel/arch/ia32/include/drivers/ remove obsolete include file  
4096 5618 d 21 h decky /trunk/kernel/arch/ia32/src/drivers/ fix very strange condition  
4095 5618 d 21 h decky /trunk/kernel/arch/ make cpu_halt() really halt the execution  
4057 5623 d 2 h decky /trunk/kernel/arch/ optional EGA support  
4047 5623 d 19 h jermar /trunk/ Improve the configuration file.

- Support for easy configuration with sane defaults.

- Fix the ambiguous MACHINE variable by introducing the PROCESSOR variable.

- Eliminate some unnecessarily detailed questions by providing defaults for the
Serengeti machine.

- Introduce CONFIG_HID_IN and CONFIG_HID_OUT variables. They help to limit the
number of offered HID devices. In the future, they can be also used to
configure the way how the serial controller devices are connected to the
keyboard / serial line modules on some platforms where we can't autodetect.
 
4042 5623 d 23 h jermar /trunk/ Complete emancipation of kernel serial controller drivers (i8042, ns16550 and
z8530). Provide a common keyboard module for PC and Sun keyboards. The serial
line module is still to follow.
 
4026 5627 d 16 h jermar /trunk/ Make the kbd port drivers platform neutral by using PIO functions.
The kernel now supplies the physical address and the kernel virtual address.
 
4022 5627 d 18 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 5627 d 19 h jermar /trunk/kernel/ There is no need to define ioport{8,16,32}_t types for each architecture separately.  
4016 5628 d 0 h decky /trunk/kernel/ better inline assembler readability using the new symbolic syntax  
4015 5628 d 2 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 5628 d 3 h decky /trunk/ cstyle  
4012 5628 d 17 h svoboda /trunk/ Task names should only contain base names of commands. Also add 'boot:' prefix for binaries loaded by the kernel.  
4011 5628 d 18 h svoboda /trunk/kernel/ String functions should be declared in string.h (and implemented in string.c) in the kernel.  
3987 5629 d 18 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 5629 d 20 h svoboda /trunk/kernel/arch/ia32/src/boot/ Rewrite rest of multiboot info parsing to C.  
3984 5629 d 20 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 5630 d 20 h jermar /trunk/kernel/ Do not set sysinfo for uspace drivers directly in the kernel drivers.  
3973 5632 d 4 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 5632 d 16 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 5635 d 2 h decky /trunk/kernel/ switch between the preference of kernel/uspace IRQ hash table  
3963 5636 d 23 h jermar /trunk/kernel/ The kernel i8042 driver should be instance-neutral.  
3947 5637 d 22 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 5637 d 22 h jermar /trunk/kernel/arch/ia32/include/ Fix ia32's pio_{read,write}_32().  
3941 5638 d 18 h jermar /trunk/kernel/ Let IRQ claim methods take irq_t * instead of the instance argument.  
3940 5638 d 22 h decky /trunk/kernel/ make hw_area API more generic
this allows mapping of EGA VRAM on ia32/amd64
 
3936 5638 d 23 h decky /trunk/ dash is not a safe character for C preprocessor, use underscore instead  
3932 5639 d 17 h jermar /trunk/kernel/ Kill arch/drivers/ega.h. Provide one-stop shopping
place for architectures with ia32 legacy I/O space.
 
3930 5639 d 17 h jermar /trunk/kernel/ Adapt most of the kernel to ioport8_t, ioport16_t and ioport32_t types.  
3929 5639 d 17 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 5639 d 19 h jermar /trunk/kernel/ Kill arch/drivers/i8042.h.  
3908 5642 d 20 h decky /trunk/ overhaul pareas: use one single physical area for the physical address space not belonging to physical memory  
3906 5643 d 16 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 5644 d 0 h jermar /trunk/kernel/arch/ia32/include/ Fix ia32 build for Pentium 3 systems.  
3902 5644 d 0 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 5644 d 18 h jermar /trunk/ Get rid of CONFIG_DEBUG_AS_WATCHPOINT.
