Betreff: [RFC] hid/sony: add autorepeat for PS3 remotes
Von: David Dillow <dave@thedillows.org>
Datum: 28.06.2013 04:28
An: linux-input@vger.kernel.org
Kopie (CC): Stephan Raue <stephan@openelec.tv>
Some applications using the PS3 remote would like to have autorepeat
from the device. Use the input subsystem's software emulation to provide
this capability, and enable those that don't need it to turn it off.
---
I'm not sure this is the correct approach, or if it is even appropriate
for a remote to do autorepeat. However, the media/rc subsystem does do
it by default, and it's been requested by users, so there is at least
some demand.
This compiled against the hid-sony driver with the PS3 remote changes
merged, but I have done no testing of it. If the approach seems
reasonable, I'll try to test it when the MythTV is idle.

ALSA: hda - Avoid outputting HDMI audio before prepare() and after close()
adapted to 3.10
From a6024295fd3290a8c9c5519a03316081ee82378a Mon Sep 17 00:00:00 2001
From: Anssi Hannula <anssi.hannula@iki.fi>
Date: Sat, 16 Feb 2013 17:42:46 +0200
Subject: [PATCH] ALSA: hda - Avoid outputting HDMI audio before prepare() and
after close()
Some HDMI codecs (at least NVIDIA 0x10de000b:0x10de0101:0x100100) start
transmitting an empty audio stream as soon as PIN_OUT and AC_DIG1_ENABLE
are enabled.
Since commit 6169b673618bf0b2518ce413b54925782a603f06 ("ALSA: hda -
Always turn on pins for HDMI/DP") this happens at first open() time, and
will continue even after close().
Additionally, some codecs (at least Intel PantherPoint HDMI) currently
continue transmitting HDMI audio even after close() in case some actual
audio was output after open() (this happens regardless of PIN_OUT).
Empty HDMI audio transmission when not intended has the effect that a
possible HDMI audio sink/receiver may prefer the empty HDMI audio stream
over an actual audio stream on its S/PDIF inputs.
To avoid the issue before first prepare(), set stream format to 0 on
codec initialization. 0 is not a valid format value for HDMI and will
prevent the audio stream from being output.
Additionally, at close() time, make sure that the stream is cleaned up.
This will ensure that the format is reset to 0 at that time, preventing
audio from being output in that case.
Thanks to OpenELEC developers and users for their help in investigating
this issue on the affected NVIDIA "ION2" hardware. Testing of the final
version on NVIDIA ION2 was done by OpenELEC user "MrXIII". Testing on
Intel PantherPoint was done by myself.

Subject: [PATCH] ALSA: hda - Name Haswell HDMI controllers better
"HDA Intel MID" is no correct name for Haswell HDMI controllers.
Give them a better name, "HDA Intel HDMI".

From 9508c6b90b3f57ecea4e7a896cf8325400fc0c6e Mon Sep 17 00:00:00 2001
From: Phillip Lougher <phillip@squashfs.org.uk>
Date: Wed, 13 Nov 2013 02:56:26 +0000
Subject: [PATCH 1/7] Squashfs: Refactor decompressor interface and code
The decompressor interface and code was written from
the point of view of single-threaded operation. In doing
so it mixed a lot of single-threaded implementation specific
aspects into the decompressor code and elsewhere which makes it
difficult to seamlessly support multiple different decompressor
implementations.
This patch does the following:
1. It removes compressor_options parsing from the decompressor
init() function. This allows the decompressor init() function
to be dynamically called to instantiate multiple decompressors,
without the compressor options needing to be read and parsed each
time.
2. It moves threading and all sleeping operations out of the
decompressors. In doing so, it makes the decompressors
non-blocking wrappers which only deal with interfacing with
the decompressor implementation.
3. It splits decompressor.[ch] into decompressor generic functions
in decompressor.[ch], and moves the single threaded
decompressor implementation into decompressor_single.c.
The result of this patch is Squashfs should now be able to
support multiple decompressors by adding new decompressor_xxx.c
files with specialised implementations of the functions in
decompressor_single.c

Subject: [PATCH 2/7] squashfs: Enhance parallel I/O
Now squashfs have used for only one stream buffer for decompression
so it hurts parallel read performance so this patch supports
multiple decompressor to enhance performance parallel I/O.
Four 1G file dd read on KVM machine which has 2 CPU and 4G memory.

Subject: [PATCH 3/7] Squashfs: add multi-threaded decompression using percpu
variable
Add a multi-threaded decompression implementation which uses
percpu variables.
Using percpu variables has advantages and disadvantages over
implementations which do not use percpu variables.
Advantages:
* the nature of percpu variables ensures decompression is
load-balanced across the multiple cores.
* simplicity.
Disadvantages: it limits decompression to one thread per core.

From 846b730e99518a1c9945afcb2afbe4d08a02ed80 Mon Sep 17 00:00:00 2001
From: Phillip Lougher <phillip@squashfs.org.uk>
Date: Mon, 18 Nov 2013 02:59:12 +0000
Subject: [PATCH 4/7] Squashfs: Generalise paging handling in the
decompressors
Further generalise the decompressors by adding a page handler
abstraction. This adds helpers to allow the decompressors
to access and process the output buffers in an implementation
independant manner.
This allows different types of output buffer to be passed
to the decompressors, with the implementation specific
aspects handled at decompression time, but without the
knowledge being held in the decompressor wrapper code.
This will allow the decompressors to handle Squashfs
cache buffers, and page cache pages.
This patch adds the abstraction and an implementation for
the caches.

Subject: [PATCH 5/7] Squashfs: Restructure squashfs_readpage()
Restructure squashfs_readpage() splitting it into separate
functions for datablocks, fragments and sparse blocks.
Move the memcpying (from squashfs cache entry) implementation of
squashfs_readpage_block into file_cache.c
This allows different implementations to be supported.

Subject: [PATCH 6/7] Squashfs: Directly decompress into the page cache for
file data
This introduces an implementation of squashfs_readpage_block()
that directly decompresses into the page cache.
This uses the previously added page handler abstraction to push
down the necessary kmap_atomic/kunmap_atomic operations on the
page cache buffers into the decompressors. This enables
direct copying into the page cache without using the slow
kmap/kunmap calls.
The code detects when multiple threads are racing in
squashfs_readpage() to decompress the same block, and avoids
this regression by falling back to using an intermediate
buffer.
This patch enhances the performance of Squashfs significantly
when multiple processes are accessing the filesystem simultaneously
because it not only reduces memcopying, but it more importantly
eliminates the lock contention on the intermediate buffer.
Using single-thread decompression.
