Keith, Sorry to trouble you. I'm making up a driver (DPC supported in the device) for our private SoC system, and the driver is regarded as a platform driver. I wonder how can I make the pcie-dpc driver detect my DPC-enabled SOC and tigger some action in my platform driver? And one more question: How to simulate DPC event in simulation env, e.g QEMU? ------------------ Regards, Wang Sheng-Huiÿôèº{.nÇ+?·?®??+%?Ëÿ±éݶ¥?wÿº{.nÇ+?·¥?{±þ?"þ)í?æèw*jg¬±¨¶????Ý¢jÿ¾«þG«?éÿ¢¸¢·¦j:+v?¨?wèjØm¶?ÿþø¯ù®w¥þ?àþf£¢·h??â?úÿ?Ù¥
