I've written a Linux device driver for a PCI device. This device performs DMA operations. An issue arise when the program crashes when a DMA operation is running. Indeed, when crashing, the device_remove() function is called by the system (as if close() were called). This function does the cleanup on the memory regions used by the PCI d...
I have a device which would be interface with my processor through pcie. I have written driver for it using the existing pci file operations. Now my problem is how do I access it from user space programs? PCI File operations do not have IOCTL support and hence I cant make an ioctl call unlike other char devices. I cannot use pci_config...
As per the PCI standard, devices are identified on the basis of Vendor Id, Device Id and the bus no. All devices of same type have identical vendor id and device id. If I put two such devices on the same bus say bus 0. How will the PCI Software Subsystem distinguish between the two? If such a case is not possible in PCI, then can such t...
I have two devices that are interfaced with PCI. I also have code for both devices that uses generic socket code. (The devices were originally connected by MII/Ethernet.) Now, I need to write a PCI device driver to transport packets back and forth between the two devices. How do I access the file descriptors opened by the socket co...
Is there any an easy (built-in, add-on, open-source or commercial) to do replication on Postgresql (Master-slave) to have the data inside the slave be scrubbed for PCI compliance while being replicated across? How about ETL tools? It does not have to be instantaneous ... up to an hour lag is acceptable but the faster the better of cour...
I am developing window application in C#. I am using the following code to generate the MAC address. I want to generate unique MAC address. I want the MAC address of the primary Lan Card. For this scenario I am using the following code. private void Form1_Load(object sender, EventArgs e) { Management...
