Once again memcheck-xli is taking % CPU. The application is a server that does some thread-creating, socket-opening, listening, accepting and of course sending and receiving. There is no "inner process" as both valgrind itself and the client program it is running execute in a single process. Signals sent to that process will be delivered to the client program as normal. If the signal causes the process to terinate then valgrind's normal exit . valgrind. Memory Management Debugger. Valgrind checks all memory operations in an application, like read, write, malloc, new, free, and delete. Valgrind can find uses of uninitialized memory, access to already freed memory, overflows, illegal stack operations, memory leaks, and any illegal new/malloc/free/delete commands. Valgrind¶. Valgrind is our tool of choice for hunting nasty memory errors and/or profiling.

  • Generic User-Level PCI Drivers
    Generic User-Level PCI Drivers Hannes Weisbach, Bj¨orn D¨obel, Adam Lackorzynski Technische Universit¨at Dresden Department of Computer Science, 01062 Dresden {weisbach,doebel,adam}@tudos.org Abstract Linux has become a popular foundation for systems with real-time requirements such as industrial control applications. In order to run such workloads on Linux, the kernel needs to provide certain properties, such as low interrupt latencies. For this purpose, the kernel has been thoroughly examined, tuned, and verified. This examination includes all aspects of the kernel, including the device drivers necessary to run the system. However, hardware may change and therefore require device driver updates or replacements. Such an update might require reevaluation of the whole kernel because of the tight integration of device drivers into the system and the manyfold ways of potential interactions. This approach is time-consuming and might require revalidation by a third party. To mitigate these costs, we propose to run device drivers in user-space applications. This allows to rely on the unmodified and already analyzed latency characteristics of the kernel when updating drivers, so that only the drivers themselves remain in the need of evaluation. In this paper, we present the Device Driver Environment (DDE), which uses the UIO framework supplemented by some modifications, which allow running any recent PCI driver from the Linux kernel without modifications in user space. We report on our implementation, discuss problems related to DMA from user space and evaluate the achieved performance. 1 Introduction in safety-critical systems would need additional au- dits and certifications to take place.

  • Valgrind: Memory Checker Tool
    Valgrind: Memory Checker Tool I Use Valgrind to check your program for memory errors and memory leaks. Valgrind can do many more things but we will focus on the memory checking part. I Use Valgrind for testing your singly linked list as follows. valgrind --leak-check=yes SimpleTest <n> I Run it on the SimpleTest.c program without the freeList function and then run it again after adding the function. I Valgrind is installed in the lab on all systems. Install it on your Fedora Linux system with the command: sudo dnf install valgrind 1/8 Valgrind: Overview I Extremely useful tool for any C/C++ programmer I Mostly known for Memcheck module, which helps find many common memory related problems in C/C++ code I Supports X86/Linux, AMD64/Linux, PPC32/Linux, PPC64/Linux and X86/Darwin (Mac OS X) I Available for X86/Linux since ~2003, actively developed 2/8 Sample (Bad) Code I We will use the following code for demonstration purposes:: The code can be found in the examples at C-examples/debug/valgrind. 1 #include <stdio.h> 2 #include <stdlib.h> 3 #define SIZE 100 4 int main() { 5 int i, sum = 0; 6 int *a = malloc(SIZE); 7 for (i = 0; i < SIZE; ++i) 8 sum += a[i]; 9 a [26] = 1; 10 a = NULL ; 11 if (sum > 0) printf("Hi!\n"); 12 return 0; 13 } I Contains many bugs. Compiles without warnings or errors.
