所以,需要在驱动中指定class code为010802h,将010802h放入pci_driver nvme_driver的id_table。之后当nvme_driver注册到PCI Bus后,PCI Bus就知道这个驱动是给class code=010802h的设备使用的。nvme_driver中有一个probe函数,nvme_probe(),这个函数才是真正加载设备的处理函数。 #define PCI_CLASS_STORAGE_EXPRESS0x0...

The block device in the Linux kernel supports multiple queues. NVMe devices take the advantages of multiple queues, multi-core CPUs, and the lock-free mechanism to achieve high performance. The NVMe driver is simpler than the SCSI driver. Accessing back-end disks using NVMe does not pass throu...
在最新的kernel 5.12.5终于看到对NVMe 1.4协议的CMB支持了,喜大普奔!散花散花! NVMe 1.4协议的CMB功能变化太大了,增加了CMBS,CRE,CMBMSC,CMBSTS。看起来终于像一个像样的功能了。 kernel驱动一直跟不上,这次驱动更新终于更新到这一块了,不枉我天天在我的dnvme驱动上修修补补。。。 PMR也抓紧跟上。。。 stati...

sudo yum install kernel kernel-tools kernel-headers kernel-devel sudo reboot 安装最新的适用于 Hyper-V 和 Azure 的 Linux 集成服务。 通过验证 lspci 的结果来检查是否需要 LIS。 如果所有 GPU 设备都按预期列出,则不需要安装 LIS。 LIS 适用于 Red Hat Enterprise Linux、CentOS 和 Oracle Linux Red Hat...
1) bitbake -c menuconfig virtual/kernel <=== at this point, I navigate to and enable the NVME device driver option 2) bitbake -c compile -f virtual/kernel 3) bitbake virtual/kernel <=== this step builds the kernel but destroys the .config file created in step 1). I didn't reali...

A Linux kernel device driver for the PCIe endpoint controller. This driver configures the PCIe controller as an endpoint, and provides an interface for higher-level software to select the configuration that is exposed to the PCIe bus. The source code for this driver is available at the following...
