2009-07-24V4L/DVB (12245): em28xx: add support for mt9m001 webcamsMauro Carvalho Chehab
Thanks to Wally <wally@voosen.eu> for bringing the issue and helping with the tests. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2009-07-24V4L/DVB (12244): em28xx: adjust vinmode/vinctl based on the stream input formatMauro Carvalho Chehab
Depending on the video input format, vinmode/vinctl needs adjustments. For TV, this is not relevant, since the supported decoders output data at the same format. However, webcam sensors may have different formats, so, this needs to be adjusted based on the device. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2009-07-24V4L/DVB (12243): em28xx: allow specifying sensor xtal frequencyMauro Carvalho Chehab
In order to properly estimate fps, mt9v011 sensor driver needs to know what is the used frequency on the sensor cristal. Adds the proper fields and initialization code for specifying the cristal frequency. Also, based on experimentation, it was noticed that the Silvercrest is outputing data at 7 fps. This means that it should be using a 6.3 MHz cristal. This information needs to be double checked later, by opening the device. Anyway, by using this value for xtal, at least now we have the correct fps report. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

2009-07-24V4L/DVB (12240): mt9v011: add a function to calculate frames per second rateMauro Carvalho Chehab
It is possible to adjust the fps rate by changing some register values. This is function of the connected Xtal at the camera sensor, being a 27 MHz cristal needed, in order to support 640x480 at 30 fps. For now, it will only calculate the values for fps. Later patches may introduce V4L2 ioctls, to allow frequency rate adjustments. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2009-07-24V4L/DVB (12239): em28xx: fix webcam scalingMauro Carvalho Chehab
While trying to fix an mt9v001 webcam, I noticed that HSCALE/VSCALE do work with em28xx + webcam. The issue is that the scaling setup depends on the number of visible rows/cols of the input image. With mt9v011 (Silvercrest), the resolution is 640x480. So, the scaling is different from a normal TV image (720x480 on NTSC). This were causing a wrong scaling and a previous patch disabled scaling. As each sensor have their different resolution setting, the xres/yres should be adjusted accordingly with the input sensor. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2009-07-24V4L/DVB (12238): em28xx: call sensor detection code for all webcam entriesMauro Carvalho Chehab
With the previous approach, autodetection were working only for the two generic entries (em275x and em2820 unknown ones). So, if someone would try to force probing an specific device, the code would not properly run the autodetection code. With the new approach, the sensor autodetection will be run not only for the two generic entries, but also do webcam specific ones. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

2009-07-24V4L/DVB (12236): em28xx: stop abusing of board->decoder for sensor informationMauro Carvalho Chehab
Instead of using em28xx board decoder field for storing sensor information, let's use instead a separate field for it. Also, as sensors are currently autodetected, there's no need of having it at the boards description. So, move it to the main em28xx struct. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2009-07-24V4L/DVB (12235): em28xx: detects sensors also with the generic em2750/2750 entryMauro Carvalho Chehab

2009-07-23dm: remove queue next_ordered workaround for barriersMike Snitzer
This patch removes DM's bio-based vs request-based conditional setting of next_ordered. For bio-based DM the next_ordered check is no longer a concern (as that check is now in the __make_request path). For request-based DM the default of QUEUE_ORDERED_NONE is now appropriate. bio-based DM was changed to work-around the previously misplaced next_ordered check with this commit: 99360b4c18f7675b50d283301d46d755affe75fd request-based DM does not yet support barriers but reacted to the above bio-based DM change with this commit: 5d67aa2366ccb8257d103d0b43df855605c3c086 The above changes are no longer needed given Neil Brown's recent fix to put the next_ordered check in the __make_request path: db64f680ba4b5c56c4be59f0698000df89ff0281 Signed-off-by: Mike Snitzer <snitzer@redhat.com> Cc: Jun'ichi Nomura <j-nomura@ce.jp.nec.com> Cc: NeilBrown <neilb@suse.de> Acked-by: Kiyoshi Ueda <k-ueda@ct.jp.nec.com> Acked-by: Mikulas Patocka <mpatocka@redhat.com> Signed-off-by: Alasdair G Kergon <agk@redhat.com>
2009-07-23dm raid1: wake kmirrord when requeueing delayed bios after remote recoveryMikulas Patocka
The recent commit 7513c2a761d69d2a93f17146b3563527d3618ba0 (dm raid1: add is_remote_recovering hook for clusters) changed do_writes() to update the ms->writes list but forgot to wake up kmirrord to process it. The rule is that when anything is being added on ms->reads, ms->writes or ms->failures and the list was empty before we must call wakeup_mirrord (for immediate processing) or delayed_wake (for delayed processing). Otherwise the bios could sit on the list indefinitely. Signed-off-by: Mikulas Patocka <mpatocka@redhat.com> CC: stable@kernel.org Signed-off-by: Alasdair G Kergon <agk@redhat.com>

2009-07-23ixgbe: Don't priority tag control frames in DCB modeLucy Liu
Certain types of control packets (LLDP, LACP, etc.) are not supposed to have a priority tag or vlan tag inserted. Ixgbe driver is currently priority tagging everything (if packet is not on a VLAN interface). This patch modifies DCB mode, so that packets marked with skb priority TC_PRIO_CONTROL are not priority tagged. It also transmits these packets on the highest priority traffic class. Programs (like dcbd) can set the skb priority using a socket option. Or, a tc filter can be configured to set the priority value. Using the value TC_PRIO_CONTROL (7) has the benefit that it is already defined in the kernel, and the bonding LACP code already sets the skb->priority field to this value.

Currently, FCoE offload feature is turned on when the kernel config has CONFIG_FCOE or CONFIG_FCOE_MODULE set. However, we really want to turn FCoE offload on when there is FCoE traffic passing and turn it off when it's just LAN traffic. Since FCoE depends on a lossless network provided by DCB, this allows us to have FCoE turned on/off when user turns on DCB using dcbtool.

2009-07-22register at91_ether using platform_driver_probeUwe Kleine-König
at91ether_probe lives in .init.text, so using platform_driver_register to register it is wrong because binding a device after the init memory is discarded (e.g. via sysfs) results in an oops. As requested by David Brownell platform_driver_probe is used instead of moving the probe function to .devinit.text as proposed initially. This saves some memory, but devices registered after the driver is probed are not bound (probably there are none) and binding via sysfs isn't possible.

2009-07-22of/mdio: Add support function for Ethernet fixed-link propertyAnton Vorontsov
Fixed-link support is broken for the ucc_eth, gianfar, and fs_enet device drivers. The "OF MDIO rework" patches removed most of the support. Instead of re-adding fixed-link stuff to the drivers, this patch adds a support function for parsing the fixed-link property and obtaining a dummy phy to match. Note: the dummy phy handling in arch/powerpc is a bit of a hack and needs to be reworked. This function is being added now to solve the regression in the Ethernet drivers, but it should be considered a temporary measure until the fixed link handling can be reworked.

2009-07-22fbmon: work around compiler bug in gcc-2.4.2Linus Torvalds
There's some odd bug in gcc-4.2 where it miscompiles a simple loop whent he loop counter is of type 'unsigned char' and it should count to 128. The compiler will incorrectly decide that a trivial loop like this: unsigned char i, ... for (i = 0; i < 128; i++) { .. is endless, and will compile it to a single instruction that just branches to itself. This was triggered by the addition of '-fno-strict-overflow', and we could play games with compiler versions and go back to '-fwrapv' instead, but the trivial way to avoid it is to just make the loop induction variable be an 'int' instead.

2009-07-21ath: add support for special 0x8000 regulatory domainLuis R. Rodriguez
Two users of ar9170 devices have now reported their cards have been programmed with a regulatory domain of 0x8000. This is not a valid regulatory domain as such these users were unable to use these devices. Since this doesn't seem to be a device EEPROM corruption we must treat it specially. It may have been possible the manufacturer intended to use 0x0 as the regulatory domain and that would ultimately yield to US but since we cannot get confirmationf or this we default this special case to one of our world regulatory domains, specifically 0x64.
