3940 5635 d 14 h decky /trunk/kernel/ make hw_area API more generic
this allows mapping of EGA VRAM on ia32/amd64
 
3929 5636 d 9 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 5639 d 12 h decky /trunk/ overhaul pareas: use one single physical area for the physical address space not belonging to physical memory  
3902 5640 d 16 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 5641 d 11 h jermar /trunk/ Get rid of CONFIG_DEBUG_ALLREGS.  
3878 5643 d 11 h decky /trunk/kernel/arch/ introduce fncptr_t and ioport_t on all platforms  
3779 5682 d 17 h jermar /trunk/kernel/ Only one kernel EGA driver to rule them all.  
3712 5701 d 9 h decky /trunk/kernel/arch/amd64/include/ synchronize drivers with ia32  
3711 5701 d 9 h decky /trunk/kernel/arch/amd64/include/ remove amd64 drivers  
3485 5773 d 10 h jermar /trunk/ Support for SYSENTER on ia32.  
3380 5808 d 11 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 5843 d 16 h decky /trunk/ remove dummy page coloring facility, which is currenty not used  
3163 5884 d 10 h jermar /trunk/ First argument to atomic functions is read-write (amd64).  
3104 5895 d 0 h svoboda /trunk/kernel/ Declare arguments for memstr.h operations as pointers instead of uintptr_t.  
3070 5897 d 16 h decky /trunk/kernel/arch/ introduce portable formatting directives
remove common types
 
3044 5898 d 10 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 5898 d 19 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 5958 d 11 h jermar /trunk/kernel/ Each architecture should only announce its endianity.
The conversion macros should be defined only once.
 
2794 5959 d 11 h jermar /trunk/kernel/ Add macros for byte swapping of uint16_t's.  
2784 5973 d 10 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 5977 d 21 h cejka /trunk/ Unified context handling code for amd64.  
2774 5977 d 22 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 6015 d 17 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 6016 d 17 h decky /trunk/kernel/ convert e820list to a generic physmem command  
2697 6037 d 18 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 6041 d 14 h decky /trunk/kernel/arch/amd64/ move cpuid tests from amd64.c to boot.S  
2630 6087 d 9 h jermar /trunk/kernel/arch/ Formatting fixes.  
2612 6096 d 12 h jermar /trunk/kernel/arch/ Cleanup.  
2606 6097 d 15 h jermar /trunk/ Support for 6 syscalls arguments on amd64.  
2467 6253 d 13 h jermar /trunk/ Improve comments for arch-specific implementations of hierarchical
4-level page tables. Improve formatting.
 
2465 6258 d 16 h jermar /trunk/ Merge arm32 into trunk.  
2453 6261 d 16 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
 
2452 6261 d 17 h jermar /trunk/kernel/ More suncc fixes.
- Removed extra semicolons after function declaration.
- Sun Studio recognizes only C99 __func__ and no gcc-specific __FUNCTION__.
In this case, a simple -D option can fix the problem.
 
2441 6266 d 10 h decky /trunk/kernel/ fix ICC compilation  
2233 6318 d 10 h decky /trunk/kernel/arch/ use the hlt instruction more properly  
2216 6320 d 11 h decky /trunk/ make thread ID 64 bit (task ID is 64 bit already)
cleanup thread syscalls
 
2089 6389 d 18 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes
 
2083 6395 d 18 h decky /trunk/kernel/ typedef elimination  
2082 6395 d 18 h decky /trunk/ __asm__ __volatile__ -> asm volatile  
2079 6396 d 12 h decky /trunk/kernel/ remove some typedefs in favor of anonymous structures
