Subject: [PATCH v3 0/3] Qcom: Add GIC-ITS support to SM8450 PCIe controllers
Date: Mon,  2 Jan 2023 16:28:18 +0530	[thread overview]
Message-ID: <20230102105821.28243-1-manivannan.sadhasivam@linaro.org> (raw)

Hello,

This series adds GIC-ITS support to SM8450 PCIe controllers for signalling
the MSIs received from endpoint devices to the CPU cores.

The GIC-ITS MSI implementation provides an advantage over internal MSI
implementation using Locality-specific Peripheral Interrupts (LPI) that
would allow MSIs to be targeted for each CPU core.

This series has been tested on SM8450 based dev board that works using an
out-of-tree dts where the MSIs from endpoint devices are distributed across
the CPU cores.

Thanks,
Mani

Changes in v2:

* Reworded the commit messages as per Lorenzo's comments
* Rebased on top of v6.2-rc1

Changes in v2:

* Swapped the Device ID for PCIe0 as it causes same issue as PCIe1
* Removed the definition of msi-map and msi-map-mask from binding
* Added Ack from Krzysztof
