Subject: dwc: tegra194: issue with card containing a bridge
Date: Tue, 15 Dec 2020 11:24:42 +0100 [thread overview]
Message-ID: <20201215102442.GA20517@suse.de> (raw)
Hi,
I am seeing an issue with next-20201211 with USB3380[1] based PCIe card
(vid:pid 10b5:3380) on Jetson AGX Xavier. Card doesn't show up in the
lspci output.
In non working case (next-20201211):
# lspci
0001:00:00.0 PCI bridge: NVIDIA Corporation Device 1ad2 (rev a1)
0001:01:00.0 SATA controller: Marvell Technology Group Ltd. Device 9171 (rev 13)
0005:00:00.0 PCI bridge: NVIDIA Corporation Device 1ad0 (rev a1)
In working case (v5.10-rc7):
# lspci
0001:00:00.0 PCI bridge: Molex Incorporated Device 1ad2 (rev a1)
0001:01:00.0 SATA controller: Marvell Technology Group Ltd. Device 9171 (rev 13)
0005:00:00.0 PCI bridge: Molex Incorporated Device 1ad0 (rev a1)
0005:01:00.0 PCI bridge: PLX Technology, Inc. Device 3380 (rev ab)
0005:02:02.0 PCI bridge: PLX Technology, Inc. Device 3380 (rev ab)
0005:03:00.0 USB controller: PLX Technology, Inc. Device 3380 (rev ab)
# lspci -t
-+-[0005:00]---00.0-[01-ff]----00.0-[02-03]----02.0-[03]----00.0
+-[0001:00]---00.0-[01-ff]----00.0
\-[0000:00]-
#lspci -v

git-bisect points to commit b9ac0f9dc8ea ("PCI: dwc: Move dw_pcie_setup_rc() to DWC common code").
dw_pcie_setup_rc() is not removed from pcie-tegra194.c in this commit.
Could the failure be caused because dw_pcie_setup_rc() is called twice now in case of tegra194?
BR,
Yousaf
