Subject: [PATCH 0/8] ALSA: non-cached memalloc helper
Date: Mon, 27 Aug 2018 10:59:45 +0200 [thread overview]
Message-ID: <20180827085953.10614-1-tiwai@suse.de> (raw)
Hi,
this is a patchset to add the non-cached page handling in the memory
allocation helpers, which have been implemented individually in
several driver codes. This also fixes a long-time bug of HD-audio
non-mmap behavior in the non-snoop mode, which was reported recently.

ALSA: memalloc: Don't align the size to power-of-two
ALSA: memalloc: Simplify snd_malloc_dev_pages() calls
ALSA: memalloc: Add non-cached buffer type
ALSA: hda: Check the non-cached stream buffers more explicitly
ALSA: hda: Use new non-cached allocation for non-snoop mode
ALSA: hda: Remove substream allocation/free ops
ALSA: intel8x0: Use the new non-cached allocation for 440MX workaround
ALSA: intel_hdmi: Use the new non-cached allocation
