4556 5619 d 13 h decky /trunk/ define endianess externally to be able to exactly specify whether we are using UTF-32LE or UTF-32BE
quit messing with BOM in UTF-32
 
4490 5634 d 2 h decky /trunk/kernel/ remove redundant index_t and count_t types (which were always quite ambiguous and not actually needed)  
4402 5650 d 0 h decky /trunk/ remove the confusing "Improved support for hyperthreading" configuration option  
4195 5699 d 1 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)
 
4126 5716 d 8 h decky /trunk/kernel/arch/ cleanup pm.h and related stuff (no change in functionality)  
4095 5717 d 3 h decky /trunk/kernel/arch/ make cpu_halt() really halt the execution  
4022 5726 d 0 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 5726 d 1 h jermar /trunk/kernel/ There is no need to define ioport{8,16,32}_t types for each architecture separately.  
4017 5726 d 5 h decky /trunk/kernel/arch/amd64/ better inline assembler readability using the new symbolic syntax  
3973 5730 d 10 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()
 
3948 5736 d 3 h jermar /trunk/kernel/arch/amd64/ Unbreak amd64.  
3940 5737 d 4 h decky /trunk/kernel/ make hw_area API more generic
this allows mapping of EGA VRAM on ia32/amd64
 
3929 5737 d 23 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 5741 d 2 h decky /trunk/ overhaul pareas: use one single physical area for the physical address space not belonging to physical memory  
3902 5742 d 6 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.
 
3890 5743 d 1 h jermar /trunk/ Get rid of CONFIG_DEBUG_ALLREGS.  
3878 5745 d 1 h decky /trunk/kernel/arch/ introduce fncptr_t and ioport_t on all platforms  
3779 5784 d 7 h jermar /trunk/kernel/ Only one kernel EGA driver to rule them all.  
3712 5802 d 23 h decky /trunk/kernel/arch/amd64/include/ synchronize drivers with ia32  
3711 5802 d 23 h decky /trunk/kernel/arch/amd64/include/ remove amd64 drivers
