From: Niklas Cassel Date: Mon, 10 Mar 2025 11:10:23 +0000 (+0100) Subject: PCI: endpoint: pci-epf-test: Expose supported IRQ types in CAPS register X-Git-Tag: v6.15-rc1~119^2~18^2~1 X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=7c3b54cf6464b4d6ba5440ae5bb44552f099a078;p=thirdparty%2Fkernel%2Flinux.git PCI: endpoint: pci-epf-test: Expose supported IRQ types in CAPS register Expose the supported IRQ types in the CAPS register. This way, the host side driver (drivers/misc/pci_endpoint_test.c) can know which IRQ types that the endpoint supports. The host side driver will make use of this information in a follow-up commit.
