Before debugging the MSI interrupt of the PCI-E, you need to ensure that the traditional interrupt is called, and then DEBUG this. Msi interruption is essentially a memory read/write event. Set the MSI address to an address in the memory (which can be 64-bit). When an MSI interruption occurs, the interrupt source will write the MSI data to the address of the MSI address. That is to say, if there are four MSI disconnections, data, data + 1, data + 2, a

I discussed MSI/msix with a friend that day. The following is a summary of the discussion: 1. The MSI-X table and PBA structure is too large, msix capability and can only be placed in the configuration space 64-255 this area, so only the table and PBA in the device memory space. Msix capability stores bar numbers and offsets to configure the spatial index table and PBA. 2.The Message Address field in MSI capability is not defined in the PCI specif

When you deploy a Hyper-V cluster, it is painful to configure the network. Different vendors or changed hardware la s are only two examples of challenges for automated deployment. In this article, I will share with you how PowerShell collects information about which network adapter is located on what PCI bus. You can use this information to rename the network adapter, combine and change the network adapter settings. We start by collecting information

Usually the bytecode length of the x86 architecture is not fixed, and x64 also follows this practice.The ARM architecture is a fixed-length byte code.At the very beginning, all arm instructions were encoded as 4 bytes. This is called arm mode.Later discovery can be compressed to two bytes. This is called thumb mode* Thumb mode and arm mode may be present in one program at the same time.In the ARMV7, another thumb-2.thumb-2 was added to the Thumb with some 4-byte length instructions.ARM64 's mach

See wiki: http://en.wikipedia.org/wiki/PCI_hole PCI Holes PCI holes are a 32-bit hardware and 32-bit operating system, which causes the computer to display less memory than the actually installed memory. This part of memory is unavailable because the device needs address space to communicate with the CPU and system software. 32-bit hardware only has 4 GB addressable address space, so in order to make the de
