3973 5605 d 9 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 5610 d 4 h jermar /trunk/kernel/ The kernel i8042 driver should be instance-neutral.  
3948 5611 d 2 h jermar /trunk/kernel/arch/amd64/ Unbreak amd64.  
3940 5612 d 3 h decky /trunk/kernel/ make hw_area API more generic
this allows mapping of EGA VRAM on ia32/amd64		  
3932 5612 d 22 h jermar /trunk/kernel/ Kill arch/drivers/ega.h. Provide one-stop shopping
place for architectures with ia32 legacy I/O space.		  
3908 5616 d 1 h decky /trunk/ overhaul pareas: use one single physical area for the physical address space not belonging to physical memory  
3906 5616 d 21 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.		  
3892 5617 d 23 h jermar /trunk/ Get rid of CONFIG_DEBUG_AS_WATCHPOINT.  
3890 5618 d 0 h jermar /trunk/ Get rid of CONFIG_DEBUG_ALLREGS.  
3880 5620 d 0 h decky /trunk/kernel/arch/ simplify configuration
introduce arch_construct_function and inb/outb (sometimes empty) on all platforms
various code cleanup		  
3851 5631 d 3 h jermar /trunk/kernel/arch/amd64/src/ Fix amd64 UP build.  
3838 5632 d 7 h decky /trunk/kernel/ make RANDI a generic macro  
3802 5644 d 5 h decky /trunk/kernel/arch/ fallback to VGA registers if VESA routine fails  
3790 5655 d 8 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 5655 d 21 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 5659 d 6 h jermar /trunk/kernel/ Only one kernel EGA driver to rule them all.  
3762 5663 d 22 h decky /trunk/kernel/arch/amd64/src/ redraw kernel console  
3707 5678 d 1 h decky /trunk/ kconsole is optional
kernel & uspace framebuffer rewrite with speedups (some things are slightly broken yet)		  
3706 5678 d 1 h decky /trunk/ cstyle & small fixes  
3274 5806 d 5 h jermar /trunk/ memcpy(), memmove() and similar functions return dst instead of src.
Fix all implementations, including those in assembly. ppc32 assembly
version didn't seem to be affected by this.		  
3222 5839 d 4 h svoboda /trunk/ Merge program-loader related stuff from dynload branch to trunk. (huge)  
3138 5863 d 8 h jermar /trunk/kernel/arch/amd64/src/ Formatting fixes for amd64 debugger.  
3104 5871 d 13 h svoboda /trunk/kernel/ Declare arguments for memstr.h operations as pointers instead of uintptr_t.  
3071 5874 d 5 h decky /trunk/kernel/ reflect changes in generic code
proper formatting directives
coding style		  
3044 5874 d 23 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.		  
2784 5949 d 23 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.		  
2783 5950 d 0 h jermar /trunk/kernel/arch/amd64/src/cpu/ Fix cstyle.  
2777 5954 d 10 h cejka /trunk/ Unified context handling code for amd64.  
2767 5959 d 1 h jermar /trunk/kernel/arch/amd64/src/ Fix breakage in non-debug amd64 build.  
2745 5971 d 9 h decky /trunk/ code cleanup (mostly signed/unsigned)
allow extra compiler warnings		  
2725 5992 d 6 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)		  
2723 5993 d 4 h decky /trunk/kernel/arch/ remove memory_print_map(), as it duplicates functionality of physmem_print()  
2713 5997 d 6 h decky /trunk/kernel/arch/amd64/src/boot/ remove fake tab  
2712 5997 d 6 h decky /trunk/kernel/ prettyprint output  
2703 6004 d 4 h jermar /trunk/kernel/arch/amd64/ Grow the initial identity mapping from 64M to 4G.
We should not allocate GDT's from above 4G or the amd64 will occassionally
triple-fault again.		  
2701 6004 d 8 h jermar /trunk/kernel/ Fix cstyle and (c) to 2008.  
2697 6014 d 7 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 6018 d 2 h decky /trunk/kernel/arch/amd64/ move cpuid tests from amd64.c to boot.S  
2630 6063 d 22 h jermar /trunk/kernel/arch/ Formatting fixes.  
2606 6074 d 4 h jermar /trunk/ Support for 6 syscalls arguments on amd64.
