From mboxrd@z Thu Jan 1 00:00:00 1970 From: Maarten Lankhorst Subject: [PATCH] ALSA: ctxfi: Bump playback substreams to 256 Date: Wed, 24 Aug 2011 00:48:59 +0200 Message-ID: <4E542E5B.6040005@gmail.com> Mime-Version: 1.0 Content-Type: text/plain; charset=ISO-8859-1 Content-Transfer-Encoding: 7bit Return-path: Sender: linux-kernel-owner@vger.kernel.org To: Takashi Iwai Cc: alsa-devel@alsa-project.org, Linux Kernel Mailing List List-Id: alsa-devel@alsa-project.org There are references in the code to 256 sources, so I tested it with 256 aplays, of which the first and last with real data and the rest playing /dev/zero . Also increase amount of page tables, so the default aplay size works.
