3779 5649 d 3 h jermar /trunk/kernel/ Only one kernel EGA driver to rule them all.  
3751 5657 d 6 h svoboda /trunk/kernel/arch/ia32/src/drivers/ Revive kernel EGA fb driver. Plus fix bug -- was using memcpy() for scrolling instead of memmove().  
3709 5667 d 22 h decky /trunk/kernel/ invert VGA 3:2:3 palette to reflect changes in revision 3692  
3707 5667 d 22 h decky /trunk/ kconsole is optional
kernel & uspace framebuffer rewrite with speedups (some things are slightly broken yet)		  
3672 5678 d 22 h jermar /trunk/ Merge sparc branch to trunk.  
3631 5689 d 20 h jermar /trunk/kernel/arch/ia32/src/ The IA-32 manual is very secretive about the fact that the SYSENTER instruction
disables interrupts (I found only one evidence of this in the instruction's
pseudo code). The sysenter_handler needs to reenable the interrupts in order to
preserve the preemptive nature of the kernel.		  
3485 5739 d 20 h jermar /trunk/ Support for SYSENTER on ia32.  
3274 5796 d 2 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.		  
3240 5806 d 7 h decky / move unfinished ObjC support to a separate branch  
3234 5810 d 2 h decky /trunk/ reintroduce support for MSIM text console in user space  
3227 5810 d 22 h decky /trunk/kernel/arch/ia32/src/drivers/ remove unnecessary newline  
3222 5829 d 1 h svoboda /trunk/ Merge program-loader related stuff from dynload branch to trunk. (huge)  
3209 5830 d 21 h jermar /trunk/kernel/arch/ia32/src/smp/ Allocate AP's GDT from first 4 GiB.  
3104 5861 d 10 h svoboda /trunk/kernel/ Declare arguments for memstr.h operations as pointers instead of uintptr_t.  
3097 5862 d 22 h decky /trunk/kernel/ resurrect klog  
3071 5864 d 3 h decky /trunk/kernel/ reflect changes in generic code
proper formatting directives
coding style		  
3043 5864 d 21 h jermar /trunk/kernel/arch/ia32/ Some inline functions in memstr.h seem to be of uncertain origin (ia32).
Replace either with built-in functions or with generic functions.		  
2784 5939 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.		  
2775 5944 d 8 h cejka /trunk/kernel/arch/ia32/src/ Added missing ia32/context.S from last commit.  
2725 5982 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)
