2841 5943 d 5 h svoboda /branches/tracing/kernel/generic/src/udebug/ Add verify_thread() to check that a thread is valid for debug ops

2838 5943 d 7 h svoboda /branches/tracing/ Respond to pending GO messages with UDEBUG_EVENT_FINISHED on terminating the debugging session. Set retval for DEBUG_END answer.  
2837 5943 d 11 h svoboda /branches/tracing/ Handle hangup message sent to kbox. Exit kbox thread when the last phone has been disconnected.  
2836 5943 d 13 h svoboda /branches/tracing/kernel/generic/src/ipc/ Fix: only create kbox thread if it doesn't exist yet

2827 5947 d 11 h svoboda /branches/tracing/kernel/generic/ Verify that a thread/task is in appropriate state when handling debug calls  
2826 5947 d 13 h svoboda /branches/tracing/kernel/generic/ Move debug_go_call from task struct to thread struct  
2825 5947 d 13 h svoboda /branches/tracing/kernel/generic/ Introduce task debug-states (udebug_task_state_t)  
2824 5947 d 14 h svoboda /branches/tracing/kernel/generic/src/udebug/ Use intermediate buffers for handling REGS_READ, REGS_WRITE and THREADS_READ  
2823 5947 d 15 h svoboda /branches/tracing/kernel/generic/src/udebug/ Improve locking in udebug.c and udebug_ipc.c  
2819 5948 d 3 h svoboda /branches/tracing/kernel/generic/src/udebug/ Fix: crashed caused by missing return in switch statement  
2818 5948 d 4 h svoboda /branches/tracing/kernel/generic/ Add MEM_WRITE debug method for writing a task's memory  
2817 5948 d 4 h svoboda /branches/tracing/kernel/generic/ Add REGS_READ and REGS_WRITE debug methods to access userspace register state (no effect yet)  
2816 5948 d 7 h svoboda /branches/tracing/kernel/generic/src/udebug/ Use thread-struct pointer for identification within debug connection  
2815 5948 d 7 h svoboda /branches/tracing/kernel/generic/ Move kernelbox debug message handling to udebug/udebug_ipc.c  
2813 5948 d 10 h svoboda /branches/tracing/ Move debug call preprocessing from ipc/sysipc.c to udebug/udebug_ipc.c

2801 5950 d 13 h svoboda /branches/tracing/ [tracing] initial debug interface support  
2800 5950 d 14 h svoboda /branches/tracing/kernel/generic/ [tracing] fix initialiation of answerbox->task in ipc_answerbox_init  
2799 5950 d 14 h svoboda /branches/tracing/ Revert all changes in tracing branch (sync to r2785 of trunk)  
2787 5959 d 7 h decky /branches/tracing/ add dynamic linking, debugging and tracing branch  
2784 5967 d 2 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 5967 d 2 h jermar /trunk/kernel/arch/amd64/src/cpu/ Fix cstyle.  
2781 5971 d 10 h cejka /trunk/ Unified context saving/restoring macros in ppc32.  
2780 5971 d 10 h cejka /trunk/ Fixed broken context_offset.h symlinks for mips32eb and ia32xen.  
2779 5971 d 11 h cejka /trunk/ Context saving/restoring macros used for mips32.  
2777 5971 d 13 h cejka /trunk/ Unified context handling code for amd64.  
2775 5971 d 14 h cejka /trunk/kernel/arch/ia32/src/ Added missing ia32/context.S from last commit.  
2774 5971 d 14 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.
