前四个字节做地址端口,后四个字节做数据端口。 然后调用pci_check_type1函数进一步检查,这主要是对1型配置方式做检查: 1 static int __init pci_check_type1(void) 2 { 3 unsigned long flags; 4 unsigned int tmp; 5 int works = 0; 6 7 local_irq_save(flags); 8 9 outb(0x01, 0xCFB); 10 ...
For devices with a PCI-Express capability, the test also performs minimal driver-related tests that check for changes in the values of particular registers in the configuration space when the driver is started, running, and stopped. For PCI-Express systems, the test also checks the ACPI table ...
uREST tool软件包解压后即可直接使用。本文以Windows 7为例介绍在Windows操作系统中配置uREST tool。 前提条件 请确保uREST tool与使用的操作系统兼容,uREST tool兼容性请参见软硬件兼容性。 若需要通过带内的方式使用uREST tool,需将uREST tool软件包上传到服务器系统。
One of the key things to keep in mind when purchasing a new PC or laptop is to check it’s upgradability options. Does your computer have additional RAM slots, PCIe SSD slots, or an HDD bay? Having the option to add extra memory down the road will help you futureproof the computer a...
Some Gen 4 NVMe PCIe SSDs can achieve 7500 MB/s read/write speeds, making them among the fastest storage devices available. The test speed for NVMe SSDs is many times faster than even the best SATA SSDs (which top out at roughly 550 MB/s)....

AHCI Link Power Management - HIPM/DIPM:微软说没见过有接PCIe的AHCI SSD会给驱动使用lowest里的DEVSLP状态,选lowest就行了。HIPM/DIPM/DEVSLP之间的关系看文档,有证据表明选lowest确实比默认的HIPM-only更省电,HIPM-only可能会阻止CPU进入更低的C-states:https://www.tenforums.com/tutorials/72971-add-ahci-link...
