In certain platforms like TI's DRA7 SoCs, use of legacy PCI interrupt is exclusive with use of MSI (Section 24.9.4.6.2.1 Legacy PCI Interrupts in http://www.ti.com/lit/ug/spruhz6i/spruhz6i.pdf). However pci_endpoint_test driver enables MSI by default in probe. In order for pci_endpoint_test to be able to test legacy interrupt, MSI should be disabled. Add a module param 'no_msi' to disable MSI (only when legacy interrupt has to be tested).

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
