Date: Mon, 11 Nov 2013 16:21:15 +0100 From: Takashi Iwai <tiwai@...e.de> To: linux-kernel@...r.kernel.org Cc: Prarit Bhargava <prarit@...hat.com>, Ming Lei <ming.lei@...onical.com>, Greg Kroah-Hartman <gregkh@...uxfoundation.org>, x86@...nel.org, amd64-microcode@...64.org Subject: [PATCH v2 0/3] Add request_firmware_direct() for microcode loader Hi, this is a revised patch series to introduce request_firmware_direct() helper for avoiding the lengthy udev issue on microcode loader. The original problem was stated in Prarit's post: https://lkml.org/lkml/2013/10/28/221 In short, microcode loader probes non-existing firmware files (which are cases with every new chip), and each probe takes 60 seconds, resulting in too long time until completed. This solution is simply avoiding the udev fallback in request_firmware() explicitly for drivers like microcode. [PATCH v2 1/3] firmware: Introduce request_firmware_direct() [PATCH v2 2/3] microcode: Use request_firmware_direct() [PATCH v2 3/3] firmware: Avoid bogus fallback warning Of course, this doesn't mean to throw away further optimizations like Prarit's patch. It can be implemented in parallel with this. v1->v2: Rebased on linux-next, add a fix for a bogus warning message thanks, Takashi -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
