2013-10-07ALSA: hda - hdmi: Fix available channel maps missing from TLVAnssi Hannula

2013-10-07ALSA: hda - hdmi: Fix channel maps with less common speakersAnssi Hannula
For some speakers and slots the CEA slot <-> speaker assignment depends on the used CEA Channel Allocation value. Therefore the from_cea_slot() and to_cea_slot() helpers currently only work correctly for the regular 7.1 speakers. Fix them to work with all speakers, taking the re-ordered CA index as input and adapting use sites accordingly. This change allows manual channel mapping to actually work for all CEA allocated speakers. Additionally, this fixes incorrect channel map reporting in automatic channel mapping mode when an affected speaker position is used (e.g. 6.1 map which contains an RC speaker).

2013-10-07ALSA: hda - hdmi: Fix unused slots being enabled in manual and non-PCM mappingsAnssi Hannula
hdmi_manual_setup_channel_mapping() and hdmi_std_setup_channel_mapping try to assign ALSA channels to HDMI channel slots and disable (i.e. silence) other slots. However, they try to disable a slot by using AC_VERB_SET_CHAN_SLOT with parameter ((alsa_ch << 8) | 0xf), while the correct parameter is ((0xf << 8) | hdmi_slot), i.e. the slot should be unassigned, not the ALSA channel. Fix that by actually disabling the unused slots. Note that this bug did not cause any (reported) issues because slots incorrectly having audio are normally ignored by a receiver if the CEA channel allocation used does not map that slot to any speaker. Additionally, the converter channel count configuration limits the number of actually active channels in any case.

2013-10-07ALSA: hda - hdmi: Fix programmed active channel countAnssi Hannula
Currently the converter channel count is set to the number of actual input channels. The audio infoframe channel count field is set similarly. However, sometimes the used channel map does not map all input channels to outputs. Notably, 3 channel modes (e.g. 2.1) require a dummy input channel so there are 4 input channels. According to the HDA specification, converter channel count should be programmed according to the number of _active_ channels. On Intel HDMI codecs (but not on NVIDIA), setting the converter channel to a higher value than there are actually mapped channels to HDMI slots will cause no audio to be output at all. Note that the effects of this issue are currently partially masked by other bugs that prevent the driver from actually unmapping channels in certain cases. For example, if a 4 channel stream is first created and prepared, it gets a FL,FR,RL,RR mapping (ALSA->HDMI slot mapping 0->0, 1->1, 2->4, 3->5). If one thereafter assigns a FR,FL,FC mapping to it, the driver will remap 2->3 but fail to unmap 2->4 and 3->5, so there are still 4 active channels and the issue will not trigger in this case. These bugs will be fixed separately. Fix the channel counts in the converter channel count field and in the audio infoframe channel count field to match the actual number of active channels.

2013-10-07ALSA: hda - hdmi: Fix incorrect default channel mapping for unusual CAsAnssi Hannula
hdmi_std_setup_channel_mapping() selects a Channel Allocation according to the sink reported speaker mask, preferring the ALSA standard layouts. If the channel allocation is not one of the ALSA standard layouts, the ALSA channels are mapped directly to HDMI channels in order. However, the function does not take into account that there a holes in the HDMI channel map. Additionally, the function tries to disable a slot by using AC_VERB_SET_CHAN_SLOT with parameter ((alsa_ch << 8) | 0xf), while the correct parameter is ((0xf << 8) | hdmi_slot), i.e. the slot should be unassigned, not the ALSA channel. Fix both of the issues for non-ALSA-default layouts. Tested on Intel HDMI with a speaker mask of FL | FR | FC | RC, which causes CA 0x06 to be selected for 4-channel audio, which causes incorrect output (sound destined to RC goes to FC and FC goes nowhere) without the patch.

2013-10-07ALSA: hda - hdmi: Fix reported channel map on common default layoutsAnssi Hannula
hdmi_setup_fake_chmap() is supposed to set the reported channel map when the channel map is not specified by the user. However, the function indexes channel_allocations[] with a wrong value and extracts the wrong nibble from hdmi_channel_mapping[], causing wrong channel maps to be shown. Fix those issues. Tested on Intel HDMI to correctly generate various channel maps, for example 3,4,14,15,7,8,5,6 (instead of incorrect 3,4,8,7,5,6,14,0) for standard 7.1 channel audio. (Note that the side and rear channels are reported as RL/RR and RLC/RRC, respectively, as per the CEA-861 standard, instead of the more traditional SL/SR and RL/RR.) Note that this only fixes the layouts that only contain traditional 7.1 speakers (2.0, 2.1, 4.0, 5.1, 7.1, etc.). E.g. the rear center of 6.1 is still being shown wrongly due to an issue with from_cea_slot() which will be fixed in a later patch.

2013-09-26ALSA: improve buffer size computations for USB PCM audioAlan Stern
This patch changes the way URBs are allocated and their sizes are determined for PCM playback in the snd-usb-audio driver. Currently the driver allocates too few URBs for endpoints that don't use implicit sync, making underruns more likely to occur. This may be a holdover from before I/O delays could be measured accurately; in any case, it is no longer necessary. The patch allocates as many URBs as possible, subject to four limitations: The total number of URBs for the endpoint is not allowed to exceed MAX_URBS (which the patch increases from 8 to 12). The total number of packets per URB is not allowed to exceed MAX_PACKS (or MAX_PACKS_HS for high-speed devices), which is decreased from 20 to 6. The total duration of queued data is not allowed to exceed MAX_QUEUE, which is decreased from 24 ms to 18 ms. The total number of ALSA frames in the output queue is not allowed to exceed the ALSA buffer size. The last requirement is the hardest to implement. Currently the number of URBs needed to fill a buffer cannot be determined in advance, because a buffer contains a fixed number of frames whereas the number of frames in an URB varies to match shifts in the device's clock rate. To solve this problem, the patch changes the logic for deciding how many packets an URB should contain. Rather than using as many as possible without exceeding an ALSA period boundary, now the driver uses only as many packets as needed to transfer a predetermined number of frames. As a result, unless the device's clock has an exceedingly variable rate, the number of URBs making up each period (and hence each buffer) will remain constant. The overall effect of the patch is that playback works better in low-latency settings. The user can still specify values for frames/period and periods/buffer that exceed the capabilities of the hardware, of course. But for values that are within those capabilities, the performance will be improved. For example, testing shows that a high-speed device can handle 32 frames/period and 3 periods/buffer at 48 KHz, whereas the current driver starts to get glitchy at 64 frames/period and 2 periods/buffer. A side effect of these changes is that the "nrpacks" module parameter is no longer used. The patch removes it.

2013-09-26ALSA : hda - not use assigned converters for all unused pinsMengdong Lin
BIOS can mark a pin as "no physical connection" if the port is used by an integrated display which is not audio capable. And audio driver will overlook such pins. On Haswell, such a disconneted pin will keep muted and connected to the 1st converter by default. But if the 1st convertor is assigned to a connected pin for audio streaming. The muted disconnected pin can make the connected pin no sound output. So this patch avoids using assigned converters for all unused pins for Haswell, including the disconected pins.

Matt found that commit 27a7c642174e ("partitions/efi: account for pmbr size in lba") caused his GPT formatted eMMC device not to boot. The reason is that this commit enforced Linux to always check the lesser of the whole disk or 2Tib for the pMBR size in LBA. While most disk partitioning tools out there create a pMBR with these characteristics, Microsoft does not, as it always sets the entry to the maximum 32-bit limitation - even though a drive may be smaller than that[1]. Loosen this check and only verify that the size is either the whole disk or 0xFFFFFFFF. No tool in its right mind would set it to any value other than these.

2013-09-14vfs: fix dentry LRU list handling and nr_dentry_unused accountingLinus Torvalds
The LRU list changes interacted badly with our nr_dentry_unused accounting, and even worse with the new DCACHE_LRU_LIST bit logic. This introduces helper functions to make sure everything follows the proper dcache d_lru list rules: the dentry cache is complicated by the fact that some of the hotpaths don't even want to look at the LRU list at all, and the fact that we use the same list entry in the dentry for both the LRU list and for our temporary shrinking lists when removing things from the LRU. The helper functions temporarily have some extra sanity checking for the flag bits that have to match the current LRU state of the dentry. We'll remove that before the final 3.12 release, but considering how easy it is to get wrong, this first cleanup version has some very particular sanity checking.

2013-09-13cifs: Avoid calling unlock_page() twice in cifs_readpage() when using fscacheSachin Prabhu
When reading a single page with cifs_readpage(), we make a call to fscache_read_or_alloc_page() which once done, asynchronously calls the completion function cifs_readpage_from_fscache_complete(). This completion function unlocks the page once it has been populated from cache. The module then attempts to unlock the page a second time in cifs_readpage() which leads to warning messages. In case of a successful call to fscache_read_or_alloc_page() we should skip the second unlock_page() since this will be called by the cifs_readpage_from_fscache_complete() once the page has been populated by fscache. With the modifications to cifs_readpage_worker(), we will need to re-grab the page lock in cifs_write_begin().

Pull aio changes from Ben LaHaise: "First off, sorry for this pull request being late in the merge window. Al had raised a couple of concerns about 2 items in the series below. I addressed the first issue (the race introduced by Gu's use of mm_populate()), but he has not provided any further details on how he wants to rework the anon_inode.c changes (which were sent out months ago but have yet to be commented on).

A sed command in scripts/config that used colons as separator was accidentally changed to use slashes, which fails when you use slashes in a value. Changing it back to colons is of course not a proper fix, but at least it will be broken in the same way it had been for four years. A proper fix is pending" * 'kconfig' of git://git.kernel.org/pub/scm/linux/kernel/git/mmarek/kbuild: scripts/config: fix variable substitution command

2013-09-13MIPS: kernel: vpe: Make vpe_attrs an array of pointers.Markos Chandras
Commit 567b21e973ccf5b0d13776e408d7c67099749eb8 "mips: convert vpe_class to use dev_groups" broke the build on MIPS since vpe_attrs should be an array of 'struct device_attribute' pointers. Fixes the following build problem: arch/mips/kernel/vpe.c:1372:2: error: missing braces around initializer [-Werror=missing-braces] arch/mips/kernel/vpe.c:1372:2: error: (near initialization for 'vpe_attrs[0]') [-Werror=missing-braces] Cc: Ralf Baechle <ralf@linux-mips.org> Cc: John Crispin <blogic@openwrt.org> Cc: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Signed-off-by: Markos Chandras <markos.chandras@imgtec.com> Cc: linux-mips@linux-mips.org Patchwork: https://patchwork.linux-mips.org/patch/5819/ Signed-off-by: Ralf Baechle <ralf@linux-mips.org>
