Hello I'v been struggled with enabling r8169 PCIe NIC and uPD72021 PCIe-USB host controller over DWC PCIe RC and need some help to solve the problem. My SoC is Exynos and it uses Designware's IP for PCIe controller internally. And there are two end point devices which are ethernet controller IC and USB host controller IC. The link training was done successfully. It can detect EPs and also loaded adequate kernel drivers after link up. After drivers are probed, I could access all PCIe configuration space and checked the MSI interrupt is also working. So outbound is just fine, meanwhile inbound operation is not working. For example, Ethernet Controller never raise MSI for Tx completion. All Tx requests are timed out. And for USB controller, there was no MSI after write request. Therefore, it seems that all DMA requests directed as "to device" are expired and never completed. My test environment and symptoms are following. [ Environment ] i) Kernel : 4.14.137+ 64bit ii) CPU : Cortex A76 (ARMv8) iii) EP devices : @pcie2 : Realtek RTL8111HS gigabit ethernet controller, @pcie3 : Renesas uPD72021 USB Host controller (*pcie0, pcie1 lanes are disabled.) [ Symptoms ] i) For USB HCD, some input devices (e.g. mouse, keyboard ..) are working, but mounting USB stick falls into timeout error. [ 336.617919] sd 2:0:0:0: [sdf] Attached SCSI disk --- 40 secs after typing 'mount /dev/sdf1 /mnt/' ---- [ 378.846029] xhci_hcd 0000:01:00.0: xHCI host not responding to stop endpoint command. [ 378.846167] xhci_hcd 0000:01:00.0: xHCI host controller not responding, assume dead ii) For Ethernet NIC, Rx operation is working, but Tx operation is never done and also falls into timeout error. [ 151.009297] NETDEV WATCHDOG: eth1 (r8169): transmit queue 0 timed out I suspect that DMA was not working properly for inbound operation but I'm not convinced. What would you recommend to check for this kind of problem ? What should I check first ? My question and guess might be humble and unclear since I'm not used to PCIe devices and its working. Any comments would be helpful and be welcomed. I attach result of lspci and PCIe log below. <lspci> 0000:00:00.0 PCI bridge: Samsung Electronics Co Ltd Device ecee (rev 01) (prog-if 00 [Normal decode]) Control: I/O+ Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR+ FastB2B- DisINTx+ Status: Cap+ 66MHz- UDF- FastB2B- ParErr- DEVSEL=fast >TAbort- <TAbort- <MAbort- >SERR- <PERR- INTx- Latency: 0 Interrupt: pin A routed to IRQ 146 Bus: primary=00, secondary=01, subordinate=ff, sec-latency=0 I/O behind bridge: 00000000-00000fff [size=4K] Memory behind bridge: 00000000-000fffff [size=1M] Prefetchable memory behind bridge: 00000000-000fffff [size=1M] Secondary status: 66MHz- FastB2B- ParErr- DEVSEL=fast >TAbort- <TAbort- <MAbort- <SERR- <PERR- BridgeCtl: Parity- SERR- NoISA- VGA- VGA16- MAbort- >Reset- FastB2B- PriDiscTmr- SecDiscTmr- DiscTmrStat- DiscTmrSERREn- Capabilities: [40] Power Management version 3 Flags: PMEClk- DSI- D1- D2- AuxCurrent=375mA PME(D0+,D1-,D2-,D3hot+,D3cold+) Status: D0 NoSoftRst- PME-Enable- DSel=0 DScale=0 PME- Capabilities: [50] MSI: Enable+ Count=1/32 Maskable+ 64bit+ Address: 0000000000000000 Data: 0000 Masking: fffffffe Pending: 00000000 Capabilities: [70] Express (v2) Root Port (Slot-), MSI 00 DevCap: MaxPayload 256 bytes, PhantFunc 0 ExtTag+ RBE+ DevCtl: CorrErr- NonFatalErr- FatalErr- UnsupReq- RlxdOrd+ ExtTag+ PhantFunc- AuxPwr- NoSnoop- MaxPayload 256 bytes, MaxReadReq 512 bytes DevSta: CorrErr+ NonFatalErr- FatalErr- UnsupReq- AuxPwr+ TransPend- LnkCap: Port #0, Speed 8GT/s, Width x0, ASPM L1, Exit Latency L1 unlimited ClockPM- Surprise- LLActRep+ BwNot+ ASPMOptComp+ LnkCtl: ASPM Disabled;
