那请教下如何配置8168为64位pcie,现在8168是spi flash启动,我已经将其配置为pcie EP,并且是pcie-32的,我现在想将其改为pcie-64,看datasheet上有23 64BIT_EN 0 64-Bit address enabled. Writable from internal bus interface.我将该位置1之后,又将BAR0大小改为1k,BAR1大小为0,BAR2为256M,BAR3为0,BAR4,BAR5为0,但是我最后发现在kernel中扫描的时候该EP的第二个BAR大小还是原来的8M,没有改过来,想请教下我该怎么配置该EP位pcie-64.
