2007-04-25[SK_BUFF]: Introduce skb_copy_from_linear_data{_offset}Arnaldo Carvalho de Melo
To clearly state the intent of copying from linear sk_buffs, _offset being a overly long variant but interesting for the sake of saving some bytes. Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com>
2007-04-25[SK_BUFF]: Convert skb->tail to sk_buff_data_tArnaldo Carvalho de Melo
So that it is also an offset from skb->head, reduces its size from 8 to 4 bytes on 64bit architectures, allowing us to combine the 4 bytes hole left by the layer headers conversion, reducing struct sk_buff size to 256 bytes, i.e. 4 64byte cachelines, and since the sk_buff slab cache is SLAB_HWCACHE_ALIGN... :-) Many calculations that previously required that skb->{transport,network, mac}_header be first converted to a pointer now can be done directly, being meaningful as offsets or pointers.

2007-04-25[SK_BUFF]: Introduce skb_mac_header()Arnaldo Carvalho de Melo
For the places where we need a pointer to the mac header, it is still legal to touch skb->mac.raw directly if just adding to, subtracting from or setting it to another layer header. This one also converts some more cases to skb_reset_mac_header() that my regex missed as it had no spaces before nor after '=', ugh.

2007-04-13DVB: dvb-usb-remote - fix oops when changing keymapOlaf Kirch
DVB USB remotes do not support changing keycode maps but set input_dev->keycodesize and input_dev->keycodemax without setting input_dev->keycode. This causes kernel oops when user tries to look up (or change) current keymap. While the proper fix would be to make remotes handle keymap changes we'll just remove keycodemax and keycodesize initialization so EVIOCGKEYCODE and EVIOCSKEYCODE will simply return -EINVAL. http://bugzilla.kernel.org/show_bug.cgi?id=8312 Signed-off-by: olaf.kirch@oracle.com Signed-off-by: Dmitry Torokhov <dtor@mail.ru> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
2007-04-02V4L/DVB (5496): Pluto2: fix incorrect TSCR register settingAndreas Oberritter
The ADEF bits in the TSCR register have different meanings in read and write mode. For this reason ADEF has to be reset on every read-modify-write operation. This patch introduces a special write function for this register, which takes care of it. Thanks to Holger Magnussen for pointing my nose at this problem.

2007-03-27V4L/DVB (5400): Core: fix several locking related problemsSimon Arlott
Fix several instances of dvb-core functions using mutex_lock_interruptible and returning -ERESTARTSYS where the calling function will either never retry or never check the return value. These cause a race condition with dvb_dmxdev_filter_free and dvb_dvr_release, both of which are filesystem release functions whose return value is ignored and will never be retried. When this happens it becomes impossible to open dvr0 again (-EBUSY) since it has not been released properly.

2007-02-21V4L/DVB (5246): Budget-ci: IR handling fixupsDavid Härdeman
Commit 00c4cc67512ada1d195b8bf3ef1db1d6b3951605 Oliver Endriss changed the budget-ci driver to use interrupt mode for i2c transfers. This also meant that a new bunch of IR bytes that were previously lost are now received, which allowed me to better understand how the MSP430 chip works. Unfortunately it also means that the current driver gets some assumptions wrong and might generate double keypresses for one IR command. The attached patch fixes this by throwing away the repeat bytes and by associating the correct command and device bytes.

Now it locks perfectly with both devices. There is a "hack" to enable probable i2c gate in zl10535 demodulator.

2007-02-21V4L/DVB (5236): Initial support for Sigmatek DVB-110 DVB-TAntti Palosaari
This patch adds driver for Sigmatek DVB-110 USB DVB-T stick. Stick has based on hardware of Qtuantek QT1010 tuner, Zarlink ZL10353 (Intel CE 6353) demodulator and Alcor Micro AU6610 DVB-T USB controller. HW is rather similar as used in MSI Megasky GL861. Currently, the driver works only in USB 2.0. In my understanding USB 1.1 is also supported by hw but I cannot test it due to lack of USB 1.1 port. Device supports only isochronous mode transfers. There is also eeprom in usb controller(at least in address range 0x80 - 0xbf) for storing data, eg. firmware. Anyway, firmware loading is not used / required by the device. There seems to be at least one unknown I2C device in address 0xa0, probably remote control or GPIO. Windows drivers reads registers from 0x00 to 0x07 from this unknown address. Driver is based on gl861 module. Tuner has a lot of problems to lock with megasky qt1010 module with this hardware with some broadcasting standards.
