2817 6024 d 10 h svoboda /branches/tracing/kernel/generic/ Add REGS_READ and REGS_WRITE debug methods to access userspace register state (no effect yet)  
2816 6024 d 13 h svoboda /branches/tracing/kernel/generic/src/udebug/ Use thread-struct pointer for identification within debug connection

2801 6026 d 20 h svoboda /branches/tracing/ [tracing] initial debug interface support  
2800 6026 d 20 h svoboda /branches/tracing/kernel/generic/ [tracing] fix initialiation of answerbox->task in ipc_answerbox_init  
2799 6026 d 21 h svoboda /branches/tracing/ Revert all changes in tracing branch (sync to r2785 of trunk)  
2787 6035 d 13 h decky /branches/tracing/ add dynamic linking, debugging and tracing branch  
2784 6043 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.		  
2783 6043 d 9 h jermar /trunk/kernel/arch/amd64/src/cpu/ Fix cstyle.  
2781 6047 d 16 h cejka /trunk/ Unified context saving/restoring macros in ppc32.  
2780 6047 d 17 h cejka /trunk/ Fixed broken context_offset.h symlinks for mips32eb and ia32xen.  
2779 6047 d 17 h cejka /trunk/ Context saving/restoring macros used for mips32.  
2777 6047 d 19 h cejka /trunk/ Unified context handling code for amd64.  
2775 6047 d 20 h cejka /trunk/kernel/arch/ia32/src/ Added missing ia32/context.S from last commit.
