It's actually commit f3fdfc4ac3a2 ("PCI: Remove host driver Kconfig selection of CONFIG_PCIEPORTBUS") that made this problem apparent. But the real bug is not in that commit, but a problem with imx6/7 not configuring a setting in the RC correctly without pcieportbus, which should not be necessary. See "[v4] PCI: imx: make msi work without CONFIG_PCIEPORTBUS=y" by Richard Zhu for a real fix. There another bug that makes this driver sometimes lose an MSI, but that regression was in v4.14 and would not be fixed by your patch, so this tigon3 problem is almost certainly caused by the previously mentioned issue with pcieportbus. > diff --git a/drivers/pci/controller/Kconfig b/drivers/pci/controller/Kconfig > index 6671946dbf66..6e4241ac0a1e 100644 > --- a/drivers/pci/controller/Kconfig > +++ b/drivers/pci/controller/Kconfig > @@ -113,6 +113,7 @@ config PCI_XGENE > bool "X-Gene PCIe controller" > depends on ARM64 || COMPILE_TEST > depends on OF || (ACPI && PCI_QUIRKS) > + select PCIEPORTBUS > help > Say Y here if you want internal PCI support on APM X-Gene SoC. >
Thank you Trent ! This patch was intended as a bug report, rather than an actual solution to be merged. I chose this format so people could easily verify the change in behaviour, just by applying the patch locally.

Awesome! I can verify this patch on our i.MX6 boards, if Richard Zhu (or anyone else) is interested. > > There another bug that makes this driver sometimes lose an MSI, but Is it the one you alerted me to before? https://patchwork.kernel.org/patch/10657987/ We are planning to use the PCIe controller in a production environment - to communicate with a tg3 based Broadcom ethernet NIC. What are the practical consequences of this bug? What is the state of the patch that fixes it? Last patch activity seems to have been in mid-November? Apologies for the trivial questions, I am by no means a PCIe expert. > that regression was in v4.14 and would not be fixed by your patch, so > this tigon3 problem is almost certainly caused by the previously > mentioned issue with pcieportbus. >

We are using a Broadcom BCM57780 ethernet adapter (Tigon3) connected to a i.MX6 PCIe controller. On a Freescale i.MX6 SoC. This combo worked ok on mainline v4.17. On mainline v4.18-rc1, a regression was introduced that caused a crash. This regression is still present in current mainline as of v4.20-rc7 Bisected the regression to the following merge head: commit 0ecda3a08746 ("Merge branch 'pci/kconfig'") When this merge head is removed, the regression disappears. This commit reverts the changes introduced by the offending merge head.
