一个允许热插拔的端口在插槽容量寄存器中有能量限制(Slot Power Limit)和能量数值(Slot Power Scale)字段,电源软件或固件初始化时必须在此字段中装入数值,表示该端口允许的最大电源提供量。同时,端口也会利用Set_Slot_Power_Limit告知接口卡。对于支持电源预算的接口卡,设备容量寄存器(Device Capabilities register)只...
Prefetchable Memory Base和Prefetchable Memory Limit低4位只读,而且决定了预取地址空间是32位还是64位,0x0表示32位,0x1表示64位。若是64位地址,则需要使用Prefetchable Base Upper 32 Bits和Prefetchable Limit Upper 32 Bits。 Prefetchable Memory Base表示预取地址空间基地址,按1MB对齐,即低20位为0。 Prefetchable ...

Sometimes it starts correctly, but I had to change the global power management in Nvidia control panel 3D settings to performance, instead of normal to make it stable over time. Without the power management change, a browser tab streaming video and audio would crash it (but not so much with...
