However lately I noticed that during the tests I still had 'pcie_pme=nomsi', so the device was not forced to use higher MSI vectors. After removing this option I noticed that hight MSI vectors are not delivered on tested platforms. After additional research I stumbled upon a patch in msm-4.14 ([1]), which describes that each group of MSI vectors is mapped to the separate interrupt. Implement corresponding mapping.[skipped] Gracious ping. Does this series stand a chance of getting into 5.20?
Bjorn, please excuse my insistence. Given that it's not merged (yet), probably it will not make it into 5.20. Is there anything preventing it from being accepted for 5.21?
dwc patches were reviewed by Rob, Mani and Johan. Stanimir has acked the bindings patch.
The dts patch should probably go via the arm-soc tree (together with additional patches adding multiple MSI IRQs to other Qualcomm SoCs).
