2013-02-08ALSA: hda - Add fixup for Haswell to enable all pin and convertor widgetsMengdong Lin
Some Haswell machines support more than one display outputs (HDMI or DP), but its BIOS may not enable the codec's 2nd and 3rd pin and output cvt widgets. This patch implements a board-specific fixup for Intel Haswell Machines: If the hidden pins are not enabled by BIOS, the driver will enable them and call common code to update the codec tree.

2013-02-08ALSA: hda - Support rereading widgets under the function groupMengdong Lin
A codec may allow software to hide some unused pin/cvt widgets. Sometimes BIOS does not enable the hidden widgets properly although they are needed for the board. Thus the driver need to enable them as a board-specific fixup and the whole tree will change. This patch implements a common code for rereading codec widgets. So the fixup code can call it after enabling the hidden widgets. Signed-off-by: Mengdong Lin <mengdong.lin@intel.com> Signed-off-by: Takashi Iwai <tiwai@suse.de>
2013-02-07ALSA: hda - Remove limit of widget connectionsTakashi Iwai
Currently we set the max number of connections to be 32, but there seems codec that gives longer connection lists like AD1988, and we see errors in proc output and else. (Though, in the case of AD1988, it's a list of all codecs connected to a single vendor widget, so this must be something fishy, but it's still valid from the h/w design POV.) This patch tries to remove this restriction. For efficiency, we still use the fixed size array in the parser, but takes a dynamic array when the size is reported to be greater than that. Now the fixed array size is found only in patch_hdmi.c, but it should be fine, as the codec itself can't support so many pins.

2013-02-04ALSA: hda - Fix default multichannel HDMI mapping regressionAnssi Hannula
Commit d45e6889ee69456a4d5b1bbb32252f460cd48fa9 ("ALSA: hda - Provide the proper channel mapping for generic HDMI driver") added support for custom channel maps in the HDA HDMI driver. Due to a mistake in an 'if' condition the custom map is always used even when no such map has been set. This causes incorrect channel mapping for multichannel audio by default. Pass per_pin->chmap_set to hdmi_setup_channel_mapping() as a parameter so that it can use it for detecting if a custom map has been set instead of checking if map is NULL (which is never the case).

2013-01-25ALSA: Make snd_printd() and snd_printdd() inlineTakashi Iwai
Because currently snd_printd() and snd_printdd() macros are expanded to empty when CONFIG_SND_DEBUG=n, a compile warning like below appears sometimes, and we had to covert it by ugly ifdefs: sound/pci/hda/patch_sigmatel.c: In function ‘stac92hd71bxx_fixup_hp’: sound/pci/hda/patch_sigmatel.c:2434:24: warning: unused variable ‘spec’ [-Wunused-variable] For "fixing" these issues better, this patch replaces snd_printd() and snd_printdd() definitions with empty inline functions instead of macros. This should have the same effect but shut up warnings like above. But since we had already put ifdefs, changing to inline functions would trigger compile errors. So, such ifdefs is removed in this patch. In addition, snd_pci_quirk name field is defined only when CONFIG_SND_DEBUG_VERBOSE is set, and the reference to it in snd_printdd() argument triggers the build errors, too. For avoiding these errors, introduce a new macro snd_pci_quirk_name() that is defined no matter how the debug option is set.

2013-01-24Btrfs: fix repeated delalloc work allocationMiao Xie
btrfs_start_delalloc_inodes() locks the delalloc_inodes list, fetches the first inode, unlocks the list, triggers btrfs_alloc_delalloc_work/ btrfs_queue_worker for this inode, and then it locks the list, checks the head of the list again. But because we don't delete the first inode that it deals with before, it will fetch the same inode. As a result, this function allocates a huge amount of btrfs_delalloc_work structures, and OOM happens. Fix this problem by splice this delalloc list.

First, though the current transaction->aborted check can stop the commit early and avoid unnecessary operations, it is too early, and some transaction handles don't end, those handles may set transaction->aborted after the check. Second, when we commit the transaction, we will wake up some worker threads to flush the space cache and inode cache. Those threads also allocate some transaction handles and may set transaction->aborted if some serious error happens. So we need more check for ->aborted when committing the transaction. Fix it.
