Web22 jun. 2012 · The only PCIe bus feature you can control via the configuration registers is whether the memory region is read prefetchable or not. There are some cacheline registers, but they have an effect during DMA, and for bridges (at least under PCI). --- Quote Start --- Typically, BARs are not cached by processor cache, however, in this case caching is ... WebExample: an integrated PCI GPU chip on a modern x86 processor. It is discoverable, thus not a platform device. Normal device driver are for those that are interfaced to the processor chip. before coming across one i2c driver. Not true. Many normal devices are interfaced to the processor, but not through an i2c bus.
