From mboxrd@z Thu Jan 1 00:00:00 1970 Return-Path: From: Christoph Hellwig To: Thomas Gleixner , Jens Axboe Cc: Keith Busch , linux-nvme@lists.infradead.org, linux-block@vger.kernel.org, linux-kernel@vger.kernel.org Subject: [PATCH 8/8] nvme: allocate queues for all possible CPUs Date: Sat, 3 Jun 2017 16:04:03 +0200 Message-Id: <20170603140403.27379-9-hch@lst.de> In-Reply-To: <20170603140403.27379-1-hch@lst.de> References: <20170603140403.27379-1-hch@lst.de> MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 List-ID: Unlike most drŅ–vers that simply pass the maximum possible vectors to pci_alloc_irq_vectors NVMe needs to configure the device before allocting the vectors, so it needs a manual update for the new scheme of using all present CPUs.
