Date: Mon, 28 Aug 2006 17:08:20 -0500 From: James Bottomley <James.Bottomley@...elEye.com> To: Greg KH <greg@...ah.com> Cc: linux-kernel <linux-kernel@...r.kernel.org> Subject: [PATCH] MODULE_FIRMWARE for binary firmware(s) From: Jon Masters <jcm@...hat.com> Right now, various kernel modules are being migrated over to use request_firmware in order to pull in binary firmware blobs from userland when the module is loaded. This makes sense. However, there is right now little mechanism in place to automatically determine which binary firmware blobs must be included with a kernel in order to satisfy the prerequisites of these drivers. This affects vendors, but also regular users to a certain extent too. The attached patch introduces MODULE_FIRMWARE as a mechanism for advertising that a particular firmware file is to be loaded - it will then show up via modinfo and could be used e.g. when packaging a kernel.
