From 4b313c69a38e28b2f002198c3909fb553e9b0176 Mon Sep 17 00:00:00 2001 From: Niklas Cassel Date: Mon, 10 Mar 2025 12:10:21 +0100 Subject: [PATCH] PCI: endpoint: Add intx_capable to epc_features struct MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit In struct pci_epc_features, an EPC driver can already specify if they support MSI (by setting msi_capable) and MSI-X (by setting msix_capable). Thus, for consistency, allow an EPC driver to specify if it supports INTx interrupts as well (by setting intx_capable). Since this struct is zero initialized, EPC drivers that want to claim INTx support will need to set intx_capable to true.
