2009-11-07V4L/DVB (13109): tda18271: fix signedness issue in ↵Seth Barry
tda18271_rf_tracking_filters_init While having tda18271 module set with debug=17 (cal & info prints) and cal=0 (delay calibration process until first use) - I discovered that during the calibration process, if the frequency test for 69750000 returned a bcal of 0 (see tda18721-fe.c in tda18271_powerscan func) that the tuner wouldn't be able to pickup any of the frequencies in the range (all the other frequencies bands returned bcal=1). I spent some time going over the code and the NXP's tda18271 spec (ver.4 of it i think) and adding a lot of debug prints and walking/stepping through the calibration process. I found that when the powerscan fails to find a frequency, the rf calibration is not run and the default value is supposed to be used in its place (pulled from the RF_CAL_map table) - but something was getting goofed up there. Now, my c coding skills are very rusty, but i think root of the problem is a signedness issue with the math operation for calculating the rf_a1 and rf_a2 values in tda18271_rf_tracking_filters_init func, which results in values like 20648 for rf_a1 (when it should probably have a value like 0, or so slightly negative that it should be zero - this bad value for rf_a1 would in turn makes the approx calc within tda18271c2_rf_tracking_filters_correction go out of whack). The simplest solution i found was to explicitly convert the signedness of the denominator to avoid the implicit conversion. The values placed into the u32 rf_freq array should never exceed about 900mhz, so i think the s32 max value shouldn't be an issue in this case. I've tested it out a little, and even when i get a bcal=0 with the modified code, the default calibration value gets used, rf_a1 is zero, and the tuner seems to lock on the stream and mythtv seems to play it fine.

2009-09-12V4L/DVB (12595): common/ir: use a struct for keycode tablesMauro Carvalho Chehab
Currently, V4L uses a scancode table whose index is the scancode and the value is the keycode. While this works, it has some drawbacks: 1) It requires that the scancode to be at the range 00-7f; 2) keycodes should be masked on 7 bits in order for it to work; 3) due to the 7 bits approach, sometimes it is not possible to replace the default keyboard to another one with a different encoding rule; 4) it is different than what is done with dvb-usb approach; 5) it requires a typedef for it to work. This is not a recommended Linux CodingStyle. This patch is part of a larger series of IR changes. It basically replaces the IR_KEYTAB_TYPE tables by a structured table: struct ir_scancode { u16 scancode; u32 keycode; }; This is very close to what dvb does. So, a further integration with DVB code will be easy. While we've changed the tables, for now, the IR keycode handling is still based on the old approach. The only notable effect is the redution of about 35% of the ir-common module size: text data bss dec hex filename 6721 29208 4 35933 8c5d old/ir-common.ko 5756 18040 4 23800 5cf8 new/ir-common.ko In thesis, we could be using above u8 for scancode, reducing even more the size of the module, but defining it as u16 is more convenient, since, on dvb, each scancode has up to 16 bits, and we currently have a few troubles with rc5, as their scancodes are defined with more than 8 bits. This patch itself shouldn't be doing any functional changes. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

KEY_CAMERA is already used for a long time with webcam drivers to take a picture. On other media drivers, due to the lack of a snapshot button, random KEY codes were sent, being KEY_SHUFFLE the most used one, probably due to cut-and-paste from other remotes, since one of them uses the same key for snapshot and shuffle.
