pci tls 1 2

1. The bus is composed of an electrical interface and a programming interface. Kernel functions used to access peripherals of Peripheral Component Interconnect (PCI, peripheral device interconnection,Because PCI bus is widely used on desktops and peripherals on larger computers today, and bus is the best supported bus in the kernel, ISA bus is basicallyIt is a "b

the PCI bridge, and the graphics card with the PCI interface can be directly connected to the primary PCI bus. The PCI-PCI Bridge is a special PCI device that connects PCI bus 0 and

Android Network Programming Series 1: JavaSecurity JSSE (SSL/TLS), javasecurityjsseAbstractTo:Java Security has been in Java for a long time and is a very important and independent forum. It contains many knowledge points, such as MD5 and DigitalSignature. Android is outside Java Seurity, extended an android. security Package, which provides the KeyChain. It contains three major specifications: JavaCryptogr

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 MS

begins. The services provided by the SSL protocol are mainly:1) Authenticate users and servers to ensure that data is sent to the correct client and server;2) Encrypt data to prevent the data from being stolen in the middle; 3) Maintain the integrity of the data and ensure that the data is not changed during transmission. First, what is SSL?SSL or Secure Socket Layer is a technology that allows Web browser

There is a very famous model in the computer network: OSI (Open Systems Interconnection, open system interconnect) model, almost all computer network teaching and research should be done on the basis of OSI, want to discuss the problems in the computer network also rely on this model. The OSI model is such a structure (from the bottom to the highest level):1, physical (physical layer)the physical layer is responsible for the final encoding of the info

connection medium is photoelectric hybrid. The specific controller is an ASIC dedicated Integrated Circuit named NRC. It adopts the 90nm process and is 2577 pin. The throughput of a single NRC is 2.56tbps. the network interface of the terminal also adopts a NIC with a similar structure, but the size is slightly smaller, with a 675 pin. The network interface is connected in PCIe 2.0 mode and the transmission rate is 6.36 Gb/s. In addition, the latency is also very low at 12000 nodes, which is on

means the server supports TLS, TCP, sctp and UDP in this order.ServiceValue determines the transport type. A client that does not support TLS will choose the second option, "sip + d2t" which means "sip over TCP. "To use TCP, the client now needs to resolve _ sip. _ tcp.arstechnica.com. We have the transport type, but now the port is unknown. it is true that the default port is 5060, but this port will only

. Like a CPU, a GPU has its own cache and registers to accelerate data access in computing. However, the GPU's primary memory also has its own storage space-which means that before running the program, the programmer must explicitly copy the data into the GPU memory. This transmission is traditionally a bottleneck for many applications, but the new PCI Express bus standard may make it more feasible to share memory between CPU and GPU in the near futur

a 16-bit segment identifier (or segment selector, as shown below) and a 32-bit intra-segment offset.The segment selector contains 13-bit index numbers, 1-bit TI table indicators, and 2-bit RPL requestor privilege levels.Each segment is represented by an 8-byte segment descriptor, which is stored in the Global Descriptor Table (GDT) or Local Descriptor Table (LDT. Generally, only one GDT is defined, and eac

is to allow a CPU access if a RAM chip is idle. The request service from another processor delays access to the CPU. Even on a single processor, the memory arbitration is used. The single-processor system contains a special processor called the DMA controller, and the DMA controller and CPU are operated concurrently. Segment in hardware: A logical address consists of a 16-bit segment identifier (or segment selector, as shown below) and a 32-bit intra-segment offset. The segment selector co
