4195 5568 d 15 h decky /trunk/kernel/arch/ detect SYSENTER/SYSEXIT support on boot
(this serves as a hint for people who try to boot HelenOS on Bochs emulating plain Pentium,
unfortunatelly it also kills VirtualBox, as it does not support SYSENTER/SYSEXIT officially,
see http://www.virtualbox.org/ticket/1248)
 
4162 5578 d 14 h jermar /trunk/kernel/arch/amd64/ Discard the eh_frame section on amd64, which improves the kernel size by
hundreds of kilobytes. Discard all other unknown sections as well.
 
4148 5581 d 1 h decky /trunk/ as kernel little brother drivers are not needed anymore, the device numbers do not have to be correlated between kernel and uspace in any way
introduce new syscall sys_device_assign_devno() for generating system-wide unique device numbers for uspace
 
4145 5581 d 1 h decky /trunk/kernel/arch/amd64/src/ fix typo  
4137 5581 d 15 h svoboda /trunk/kernel/ Make optionality of symbol information less intrusive per Jakub's request. Also, improve symtab function names and update their semantics.  
4132 5582 d 14 h svoboda /trunk/ Make kernel symbol information optional.  
4127 5585 d 23 h decky /trunk/ parse VESA mode from a string
unify VESA initialization for ia32 and amd64
 
4126 5585 d 23 h decky /trunk/kernel/arch/ cleanup pm.h and related stuff (no change in functionality)  
4102 5586 d 18 h decky /trunk/kernel/arch/amd64/src/ update for the new scheme of wiring device drivers to keyboard/serial modules
use ega_redraw() only if it is compiled in
 
4101 5586 d 18 h decky /trunk/kernel/arch/ remove duplicate part of the debugger message
(it is already printed by kconsole)
 
4100 5586 d 18 h decky /trunk/kernel/arch/amd64/src/boot/ whitespace changes  
4095 5586 d 18 h decky /trunk/kernel/arch/ make cpu_halt() really halt the execution  
4057 5590 d 22 h decky /trunk/kernel/arch/ optional EGA support  
4047 5591 d 15 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 5591 d 20 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 5595 d 13 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 5595 d 14 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 5595 d 15 h jermar /trunk/kernel/ There is no need to define ioport{8,16,32}_t types for each architecture separately.  
4017 5595 d 20 h decky /trunk/kernel/arch/amd64/ better inline assembler readability using the new symbolic syntax  
3987 5597 d 15 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.  
3982 5598 d 17 h jermar /trunk/kernel/ Do not set sysinfo for uspace drivers directly in the kernel drivers.  
3973 5600 d 0 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()
 
3963 5604 d 20 h jermar /trunk/kernel/ The kernel i8042 driver should be instance-neutral.  
3948 5605 d 18 h jermar /trunk/kernel/arch/amd64/ Unbreak amd64.  
3940 5606 d 18 h decky /trunk/kernel/ make hw_area API more generic
this allows mapping of EGA VRAM on ia32/amd64
 
3932 5607 d 13 h jermar /trunk/kernel/ Kill arch/drivers/ega.h. Provide one-stop shopping
place for architectures with ia32 legacy I/O space.
 
3929 5607 d 14 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.
 
3908 5610 d 17 h decky /trunk/ overhaul pareas: use one single physical area for the physical address space not belonging to physical memory  
3906 5611 d 12 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.
 
3902 5611 d 20 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 5612 d 15 h jermar /trunk/ Get rid of CONFIG_DEBUG_AS_WATCHPOINT.  
3890 5612 d 15 h jermar /trunk/ Get rid of CONFIG_DEBUG_ALLREGS.  
3880 5614 d 15 h decky /trunk/kernel/arch/ simplify configuration
introduce arch_construct_function and inb/outb (sometimes empty) on all platforms
various code cleanup
 
3879 5614 d 16 h decky /trunk/kernel/arch/ simplify configuration in Makefiles  
3878 5614 d 16 h decky /trunk/kernel/arch/ introduce fncptr_t and ioport_t on all platforms  
3851 5625 d 18 h jermar /trunk/kernel/arch/amd64/src/ Fix amd64 UP build.  
3838 5626 d 22 h decky /trunk/kernel/ make RANDI a generic macro  
3802 5638 d 20 h decky /trunk/kernel/arch/ fallback to VGA registers if VESA routine fails  
3790 5650 d 0 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 5650 d 13 h svoboda /trunk/kernel/ Unify newlines in fault_if_from_uspace() format strings. (Remove them and print newline automatically). Also start messages with caps.
