Subject: [PATCH] PCI: qcom: Add support for handling MSIs from 8 endpoints
Date: Tue, 14 Dec 2021 15:43:19 +0530 [thread overview]
Message-ID: <20211214101319.25258-1-manivannan.sadhasivam@linaro.org> (raw)
The DWC controller used in the Qcom Platforms are capable of addressing the
MSIs generated from 8 different endpoints each with 32 vectors (256 in
total). Currently the driver is using the default value of addressing the
MSIs from 1 endpoint only. Extend it by passing the MAX_MSI_IRQS to the
num_vectors field of pcie_port structure.
