2009-09-01xfs: factor out inode initialisationDave Chinner
Factor out code to initialize new inode clusters into a function of it's own. This keeps xfs_ialloc_ag_alloc smaller and better structured and enables a future inode cluster initialization transaction. Also initialize the agno variable earlier in xfs_ialloc_ag_alloc to avoid repeated byte swaps.

The locking in xfs_iget_cache_hit currently has numerous problems: - we clear the reclaim tag without i_flags_lock which protects modifications to it - we call inode_init_always which can sleep with pag_ici_lock held (this is oss.sgi.com BZ #819) - we acquire and drop i_flags_lock a lot and thus provide no consistency between the various flags we set/clear under it This patch fixes all that with a major revamp of the locking in the function.

2009-08-15poll/select: initialize triggered field of struct poll_wqueuesGuillaume Knispel
The triggered field of struct poll_wqueues introduced in commit 5f820f648c92a5ecc771a96b3c29aa6e90013bba ("poll: allow f_op->poll to sleep"). It was first set to 1 in pollwake() (now __pollwake() ), tested and later set to 0 in poll_schedule_timeout(), but not initialized before. As a result when the process needs to sleep, triggered was likely to be non-zero even if pollwake() is not called before the first poll_schedule_timeout(), meaning schedule_hrtimeout_range() would not be called and an extra loop calling all ->poll() would be done. This patch initialize triggered to 0 in poll_initwait() so the ->poll() are not called twice before the process goes to sleep when it needs to.

2009-08-13V4L/DVB (12440): Use kzalloc for frontend states to have struct dvb_frontend ↵Matthias Schwarzott
properly This patch changes most frontend drivers to allocate their state structure via kzalloc and not kmalloc. This is done to properly initialize the embedded "struct dvb_frontend frontend" field, that they all have. The visible effect of this struct being uninitalized is, that the member "id" that is used to set the name of kernel thread is totally random. Some board drivers (for example cx88-dvb) set this "id" via videobuf_dvb_alloc_frontend but most do not. So I at least get random id values for saa7134, flexcop and ttpci based cards. It looks like this in dmesg: DVB: registering adapter 1 frontend -10551321 (ST STV0299 DVB-S) The related kernel thread then also gets a strange name like "kdvb-ad-1-fe--1".

2009-08-13V4L/DVB (12429): v4l2-ioctl: fix G_STD and G_PARM default handlersHans Verkuil
The v4l core supplies default handlers for G_STD and G_PARM. However, both default handlers are buggy. This patch fixes the following: 1) If no g_std is supplied and current_norm == 0, then this driver does not support TV video standards (e.g. a radio or webcam driver). Return -EINVAL. This ensures that there is no bogus VIDIOC_G_STD support for such drivers. 2) The default VIDIOC_G_PARM handler used current_norm instead of first checking if the driver supported g_std and calling that to get the norm. It also didn't check if current_norm was 0, since in that case the driver does not support TV standards (or no standard was set at all) and the default handler should return -EINVAL. Note that I am very unhappy with these default handlers: I think they basically behave like some very strange and unexpected side-effect.

2009-08-13V4L/DVB (12405): em28xx-cards: move register 0x13 setting to the proper placeMauro Carvalho Chehab
Register 0x13 seems to be a sort of image control, maybe gamma, white level or black level. Lower values produce better images, while higher values increases the contrast and shifts colors to green. 0xff produces a black image. This register is not Silvercrest-specific, so its code should be moved to a better place. If this register is left alone, a random value can be found at the register, producing weird results. While here, let's remove register 0x0d, as it had no noticed effect at the image. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2009-08-13V4L/DVB (12411): em28xx: Fix artifacts with Silvercrest webcamMauro Carvalho Chehab
Silvercrest mt9v011 sensor produces a 640x480 image. However, previously, the code were getting only half of the lines and merging two consecutive frames to "produce" a 640x480 image. With the addition of progressive mode, now em28xx is working with a full image. However, when the number of lines is bigger than 240, the beginning of some odd lines are filled with blank. After lots of testing, and physically checking the device for a Xtal, it was noticed experimentally that mt9v011 is using em28xx XCLK as its clock. Due to that, changing XCLK value changes the maximum speed of the stream. At the tests, it were possible to produce up to 32 fps, using a 30 MHz XCLK. However, at that rate, the artifacts happen even at 320x240. Lower values of XCLK produces artifacts only at 640x480. At some values of xclk (for example XCLKK = 6 MHz, 640x480), it is possible to see an invalid sucession of artifacts with this pattern: .xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx ..xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx ...xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx ....xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx .xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx ..xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx ...xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx ....xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx (where the dots represent the blanked pixels) So, it seems that a waveform in the format of a ramp is interferring at the image. The cause of this interference is currently unknown. Some possibilities are: - electrical interference (maybe this device is broken?); - some issue at mt9v011 programming; - some bug at em28xx chip. So, for now, let's be conservative and use a value of XCLK that we know for sure that it won't cause artifacts. As I'm waiting for more of such devices with different em28xx chipset revisions, I'll have the opportunity to double check the issue with other pieces of hardware. Later patches can vary XCLK depending on the vertical resolutions, if a proper fix is not discovered. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

2009-08-13V4L/DVB (12406): em28xx: fix: don't do image interlacing on webcamsMauro Carvalho Chehab
Due to historical reasons, em28xx driver gets two consecutive frames and fold them into an unique framing, doing interlacing. While this works fine for TV images, this produces two bad effects with webcams: 1) webcam images are progressive. Merging two consecutive images produce interlacing artifacts on the image; 2) since the driver needs to get two frames, it reduces the maximum frame rate by two.

2009-08-13V4L/DVB (12362): cx23885-417: fix manipulation of tvnormsMichael Krufky
Currently, the VIDIOC_S_STD ioctl just returns -EINVAL regardless of the norm passed. This patch sets cx23885_mpeg_template.tvnorms and cx23885_mpeg_template.current_norm so that the VIDIOC_S_STD will work. Thanks to Joseph Yasi for pointing this out, even though this particular fix was already pushed into a development repository, merge priority of this changeset has been escalated as a result of Joseph posting this identical patch.

2009-08-13V4L/DVB (12341): zl10353 and qt1010: fix stack corruption bugJan Nikitenko
Fixes stack corruption bug present in dump_regs function of zl10353 and qt1010 drivers: the buffer buf was one byte smaller than required - there are 4 chars for address prefix, 16 * 3 chars for dump of 16 eeprom bytes per line and 1 byte for zero ending the string required, i.e. 53 bytes, but only 52 were provided. The one byte missing in stack based buffer buf can cause stack corruption possibly leading to kernel oops, as discovered originally with af9015 driver (af9015: fix stack corruption bug).

Some mt9v011 webcams report 0x8332 chip version, instead of 0x8243. From the revision history at the mt9v011 datasheet, it seems that the chip version has changed from the first release of the chip.
