2784 5952 d 8 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.
 
2775 5956 d 20 h cejka /trunk/kernel/arch/ia32/src/ Added missing ia32/context.S from last commit.  
2774 5956 d 20 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 5994 d 15 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 5995 d 13 h decky /trunk/kernel/arch/ remove memory_print_map(), as it duplicates functionality of physmem_print()  
2721 5995 d 15 h decky /trunk/kernel/ convert e820list to a generic physmem command  
2712 5999 d 15 h decky /trunk/kernel/ prettyprint output  
2702 6006 d 16 h decky /trunk/kernel/arch/ia32/src/mm/ change cstyle to human-readable form  
2701 6006 d 17 h jermar /trunk/kernel/ Fix cstyle and (c) to 2008.  
2697 6016 d 16 h decky /trunk/kernel/ amd64: shorten kernel address space by 2 GB to support proper mapping of more than 2 GB of physical memory  
2630 6066 d 7 h jermar /trunk/kernel/arch/ Formatting fixes.  
2613 6075 d 10 h jermar /trunk/ Support for six syscall arguments for ia32.  
2612 6075 d 10 h jermar /trunk/kernel/arch/ Cleanup.  
2599 6082 d 6 h decky /trunk/kernel/ replace prescott cpu type with currently more known category  
2575 6097 d 10 h jermar /trunk/kernel/arch/ia32/src/ Formatting fixes.  
2482 6218 d 5 h jermar /trunk/ Goodbye pseudo threads, welcome fibrils.
The renaming might still be incomplete.
 
2467 6232 d 12 h jermar /trunk/ Improve comments for arch-specific implementations of hierarchical
4-level page tables. Improve formatting.
 
2465 6237 d 14 h jermar /trunk/ Merge arm32 into trunk.  
2462 6239 d 9 h jermar /trunk/kernel/ Replace gcc-specific __FUNCTION__ with C99 __func__.
suncc's xregs=no%float can be used only on sparc64.
 
2460 6239 d 9 h jermar /trunk/kernel/ Better infrastructure for building with different compilers.
Separate ICC_CFLAGS added, SUNCC_CFLAGS extended.
 
2459 6239 d 13 h jermar /trunk/kernel/arch/ Fix a bug in ia32 and ia32xen Sun Studio builds.
In arch Makefile.inc, SUNCC_CFLAGS can only be appended via the += operator.
 
2454 6240 d 8 h jermar /trunk/kernel/ A bit of infrastructure for building with different compilers.
CFLAGS split into GCC_CFLAGS and SUNCC_CFLAGS.
As of now, there are no separate ICC_CFLAGS, but can be easily added.
 
2444 6245 d 6 h jermar /trunk/kernel/ First fixes for suncc support.
It is going to be a long way...
 
2441 6245 d 8 h decky /trunk/kernel/ fix ICC compilation  
2439 6245 d 8 h decky /trunk/kernel/arch/ia32/src/ fix ICC compilation  
2438 6245 d 8 h decky /trunk/ update for new compiler configuration scheme  
2317 6267 d 6 h decky /trunk/kernel/arch/ia32/include/ remove outstanding move  
2316 6267 d 6 h decky /trunk/kernel/arch/ia32/include/ remove forgotten movs  
2314 6267 d 7 h decky /trunk/kernel/arch/ia32/include/ allow to compile with -O0  
2302 6272 d 12 h decky /trunk/ force VGA palette to 3:2:3 palette on 8 bpp modes
(this fixes ticket #33)
 
2233 6297 d 8 h decky /trunk/kernel/arch/ use the hlt instruction more properly  
2227 6297 d 23 h decky /trunk/kernel/ start shutdown infrastructure  
2222 6298 d 9 h decky /trunk/kernel/ map kernel pages explicitly as writable (this solves compatibility issues with Intel Core 2)
make VESA framebuffer initialization more robust
 
2221 6298 d 10 h decky /trunk/kernel/arch/ia32/src/boot/ fix typo in comment  
2220 6298 d 10 h decky /trunk/kernel/arch/ia32/src/boot/ check for PSE support, add error message on PSE not present
make initial mapping explicitly writeable, turn PAE explicitly off (just in case)
 
2218 6299 d 6 h decky /trunk/kernel/ support the possibility to send EOI or Interrupt Acknowledgement
prior to processing the interrupt
(this is essential on some architectures to prevent preemption deadlock)
 
2217 6299 d 7 h jermar /trunk/kernel/arch/ia32/src/smp/ On SMP amd64 and ia32 systems, release the irq->lock
before calling clock() from the interrupt handler.
This is important for maintaining kernel preemption
since no preemption can take place while a spinlock
is held.
 
2216 6299 d 9 h decky /trunk/ make thread ID 64 bit (task ID is 64 bit already)
cleanup thread syscalls
 
2125 6354 d 9 h decky /trunk/ experimental support for Objective C
(disabled by default)
 
2107 6362 d 8 h jermar /trunk/ When clock() is called by an external interrupt dispatched by the IRQ dispatcher,
no spinlock can be held or the kernel will not be preemptive. This fixes Ticket #24.

Formating and indentation fixes.
