3940 5664 d 0 h decky /trunk/kernel/ make hw_area API more generic
this allows mapping of EGA VRAM on ia32/amd64
 
3929 5664 d 20 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 5667 d 23 h decky /trunk/ overhaul pareas: use one single physical area for the physical address space not belonging to physical memory  
3902 5669 d 2 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 5669 d 21 h jermar /trunk/ Get rid of CONFIG_DEBUG_ALLREGS.  
3878 5671 d 22 h decky /trunk/kernel/arch/ introduce fncptr_t and ioport_t on all platforms  
3779 5711 d 4 h jermar /trunk/kernel/ Only one kernel EGA driver to rule them all.  
3712 5729 d 20 h decky /trunk/kernel/arch/amd64/include/ synchronize drivers with ia32  
3711 5729 d 20 h decky /trunk/kernel/arch/amd64/include/ remove amd64 drivers  
3485 5801 d 20 h jermar /trunk/ Support for SYSENTER on ia32.  
3380 5836 d 22 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 5872 d 2 h decky /trunk/ remove dummy page coloring facility, which is currenty not used  
3163 5912 d 20 h jermar /trunk/ First argument to atomic functions is read-write (amd64).  
3104 5923 d 10 h svoboda /trunk/kernel/ Declare arguments for memstr.h operations as pointers instead of uintptr_t.  
3070 5926 d 3 h decky /trunk/kernel/arch/ introduce portable formatting directives
remove common types
 
3044 5926 d 21 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 5927 d 5 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 5986 d 22 h jermar /trunk/kernel/ Each architecture should only announce its endianity.
The conversion macros should be defined only once.
 
2794 5987 d 21 h jermar /trunk/kernel/ Add macros for byte swapping of uint16_t's.  
2784 6001 d 20 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 6006 d 7 h cejka /trunk/ Unified context handling code for amd64.  
2774 6006 d 8 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 6044 d 3 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 6045 d 4 h decky /trunk/kernel/ convert e820list to a generic physmem command  
2697 6066 d 4 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 6070 d 0 h decky /trunk/kernel/arch/amd64/ move cpuid tests from amd64.c to boot.S  
2630 6115 d 19 h jermar /trunk/kernel/arch/ Formatting fixes.  
2612 6124 d 22 h jermar /trunk/kernel/arch/ Cleanup.  
2606 6126 d 1 h jermar /trunk/ Support for 6 syscalls arguments on amd64.  
2467 6282 d 0 h jermar /trunk/ Improve comments for arch-specific implementations of hierarchical
4-level page tables. Improve formatting.
 
2465 6287 d 3 h jermar /trunk/ Merge arm32 into trunk.  
2453 6290 d 2 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 6290 d 4 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 6294 d 20 h decky /trunk/kernel/ fix ICC compilation  
2233 6346 d 21 h decky /trunk/kernel/arch/ use the hlt instruction more properly  
2216 6348 d 22 h decky /trunk/ make thread ID 64 bit (task ID is 64 bit already)
cleanup thread syscalls
 
2089 6418 d 4 h decky /trunk/ huge type system cleanup
remove cyclical type dependencies across multiple header files
many minor coding style fixes
 
2083 6424 d 4 h decky /trunk/kernel/ typedef elimination  
2082 6424 d 4 h decky /trunk/ __asm__ __volatile__ -> asm volatile  
2079 6424 d 23 h decky /trunk/kernel/ remove some typedefs in favor of anonymous structures
