From 92c7c8a7d6e03eb4c0a3c5888e35dbc45f24744c Mon Sep 17 00:00:00 2001 From: Takashi Iwai Date: Tue, 24 Mar 2009 07:32:14 +0100 Subject: [PATCH 1/3] ALSA: hda - Cache PCM and STREAM parameters queries Cache quries for PCM and STREAM parameters as well as ampcap and pincap sharing the hash table. This will reduce the superfluous access of the same codec verbs.

Especially falling back to the single-command mode causes the fatal problem on many systems. In this patch, the problematic verb is re-issued again after the error (even with polling mode) instead of the single-cmd mode. The single-cmd mode will be used only when specified via the command option explicitly, mainly just for testing.
