Subject: [PATCHv8 08/12] PCI: layerscape: Modify the MSIX to the doorbell mode
Date: Fri, 18 Sep 2020 16:00:20 +0800 [thread overview]
Message-ID: <20200918080024.13639-9-Zhiqiang.Hou@nxp.com> (raw)
In-Reply-To: <20200918080024.13639-1-Zhiqiang.Hou@nxp.com>
From: Xiaowei Bao <xiaowei.bao@nxp.com>
dw_pcie_ep_raise_msix_irq was never called in the exisitng driver
before, because the ls1046a platform don't support the MSIX feature
and msix_capable was always set to false.
Now that add the ls1088a platform with MSIX support, use the doorbell
method to support the MSIX feature.
