4195 5612 d 6 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 5629 d 13 h decky /trunk/kernel/arch/ cleanup pm.h and related stuff (no change in functionality)  
4095 5630 d 8 h decky /trunk/kernel/arch/ make cpu_halt() really halt the execution  
4022 5639 d 5 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 5639 d 6 h jermar /trunk/kernel/ There is no need to define ioport{8,16,32}_t types for each architecture separately.  
4017 5639 d 10 h decky /trunk/kernel/arch/amd64/ better inline assembler readability using the new symbolic syntax  
3973 5643 d 15 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 5649 d 8 h jermar /trunk/kernel/arch/amd64/ Unbreak amd64.  
3940 5650 d 9 h decky /trunk/kernel/ make hw_area API more generic
this allows mapping of EGA VRAM on ia32/amd64
 
3929 5651 d 4 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 5654 d 7 h decky /trunk/ overhaul pareas: use one single physical area for the physical address space not belonging to physical memory  
3902 5655 d 11 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 5656 d 6 h jermar /trunk/ Get rid of CONFIG_DEBUG_ALLREGS.  
3878 5658 d 6 h decky /trunk/kernel/arch/ introduce fncptr_t and ioport_t on all platforms  
3779 5697 d 12 h jermar /trunk/kernel/ Only one kernel EGA driver to rule them all.  
3712 5716 d 4 h decky /trunk/kernel/arch/amd64/include/ synchronize drivers with ia32  
3711 5716 d 4 h decky /trunk/kernel/arch/amd64/include/ remove amd64 drivers  
3485 5788 d 5 h jermar /trunk/ Support for SYSENTER on ia32.  
3380 5823 d 6 h jermar /trunk/kernel/arch/amd64/include/ Prevent 'tmp' in amd64's atomic_lock_arch() from being allocated
to the same register as 'val->count'.
 
3233 5858 d 11 h decky /trunk/ remove dummy page coloring facility, which is currenty not used  
3163 5899 d 5 h jermar /trunk/ First argument to atomic functions is read-write (amd64).  
3104 5909 d 19 h svoboda /trunk/kernel/ Declare arguments for memstr.h operations as pointers instead of uintptr_t.  
3070 5912 d 11 h decky /trunk/kernel/arch/ introduce portable formatting directives
remove common types
 
3044 5913 d 5 h jermar /trunk/kernel/arch/amd64/ Some inline functions in memstr.h seem to be of uncertain origin (amd64).
Replace either with built-in functions or with generic functions.
 
3040 5913 d 13 h svoboda /trunk/kernel/arch/amd64/include/ Fix register-constraint typo in amd64 memstr.h and add two '&'s for symmetry's sake. (None were really causing trouble)  
2797 5973 d 6 h jermar /trunk/kernel/ Each architecture should only announce its endianity.
The conversion macros should be defined only once.
 
2794 5974 d 6 h jermar /trunk/kernel/ Add macros for byte swapping of uint16_t's.  
2784 5988 d 5 h jermar /trunk/kernel/arch/ Fortify ia32 and amd64 kernels against mallicious uspace applications that set
DF prior to entering the kernel. For AMD64 syscalls, we don't use the CLD
instruction, but make use of the SFMASK MSR instead. Simics works fine with
it, but QEMU seems to have a problem.
 
2777 5992 d 16 h cejka /trunk/ Unified context handling code for amd64.  
2774 5992 d 17 h cejka /trunk/kernel/arch/ Context.s renamed to context.S for ia32 and fixed links for ia32xen.
Added asm macros for context save/restore and offset definitions.
 
2725 6030 d 12 h decky /trunk/kernel/ remove config.memory_size, get_memory_size() and memory_init.{c|d}
the amount of available memory can be calculated from the sizes of the zones
add FRAMES2SIZE, SIZE2KB and SIZE2MB functions/macros (code readability)
 
2721 6031 d 12 h decky /trunk/kernel/ convert e820list to a generic physmem command  
2697 6052 d 13 h decky /trunk/kernel/ amd64: shorten kernel address space by 2 GB to support proper mapping of more than 2 GB of physical memory  
2692 6056 d 8 h decky /trunk/kernel/arch/amd64/ move cpuid tests from amd64.c to boot.S  
2630 6102 d 4 h jermar /trunk/kernel/arch/ Formatting fixes.  
2612 6111 d 6 h jermar /trunk/kernel/arch/ Cleanup.  
2606 6112 d 10 h jermar /trunk/ Support for 6 syscalls arguments on amd64.  
2467 6268 d 8 h jermar /trunk/ Improve comments for arch-specific implementations of hierarchical
4-level page tables. Improve formatting.
 
2465 6273 d 11 h jermar /trunk/ Merge arm32 into trunk.  
2453 6276 d 11 h jermar /trunk/kernel/ More suncc fixes.
- remove more empty declarations
- add options to turn errors on empty structs into warnings and options to
silence these warnings
