2009-01-02V4L/DVB (10170): tuner-simple: prevent possible OOPS caused by divide by ↵Michael Krufky
zero error A user reported the following OOPS with his pcHDTV HD5500 card, which uses a cx88 PCI bridge with a LG-TDVS-H06xF frontend module, made up of a TUA6034 tuner, TDA988x IF demod, and LG DT3303 ATSC/QAM demod. Somehow, tuner-core gets loaded before the digital driver configures the tuner, and tuner-core somehow incorrectly sets the tuner type to LG NTSC (TAPE series) instead of LG TDVS-H06xF. This tuner type does not have the tuning stepsize defined, so an OOPS occurs during the digital tune function. We still dont know how the type gets set incorrectly in the first place. The user has a tainted kernel with a binary nividia module, which COULD have something to do with this, but it's hard to say for sure. Nevertheless, to avoid this division by zero, we should check that stepsize is defined. If stepsize is not defined, print an error and bail out on the tune request. cx8800 0000:05:01.0: PCI INT A -> GSI 19 (level, low) -> IRQ 19 cx88[0]: subsystem: 7063:5500, board: pcHDTV HD5500 HDTV [card=47,autodetected], frontend(s): 1 cx88[0]: TV tuner type 47, Radio tuner type -1 tuner' 2-0043: chip found @ 0x86 (cx88[0]) tda9887 2-0043: creating new instance tda9887 2-0043: tda988[5/6/7] found tuner' 2-0061: chip found @ 0xc2 (cx88[0]) tuner-simple 2-0061: creating new instance tuner-simple 2-0061: type set to 47 (LG NTSC (TAPE series)) cx88[0]/0: found at 0000:05:01.0, rev: 5, irq: 19, latency: 32, mmio: 0xea000000 cx88[0]/0: registered device video1 [v4l2] cx88[0]/0: registered device vbi1 cx88_audio 0000:05:01.1: PCI INT A -> GSI 19 (level, low) -> IRQ 19 cx88[0]/1: CX88x/0: ALSA support for cx2388x boards cx88[0]/2: cx2388x 8802 Driver Manager cx88-mpeg driver manager 0000:05:01.2: PCI INT A -> GSI 19 (level, low) -> IRQ 19 cx88[0]/2: found at 0000:05:01.2, rev: 5, irq: 19, latency: 32, mmio: 0xec000000 cx8802_probe() allocating 1 frontend(s) cx88/2: cx2388x dvb driver version 0.0.6 loaded cx88/2: registering cx8802 driver, type: dvb access: shared cx88[0]/2: subsystem: 7063:5500, board: pcHDTV HD5500 HDTV [card=47] cx88[0]/2: cx2388x based DVB/ATSC card tuner-simple 2-0061: attaching existing instance tuner-simple 2-0061: type set to 64 (LG NTSC (TAPE series)) tda9887 2-0043: attaching existing instance DVB: registering new adapter (cx88[0]) DVB: registering adapter 0 frontend 0 (LG Electronics LGDT3303 VSB/QAM Frontend)...

The init_fw option was broken for the HVR-950q because we would call the reset callback inside of dvb_attach() and the callback had not been setup yet. Michael Krufky (who added the init_fw feature) says it's no longer required, so just remove the option completely.

tuner-xc3028 can be put to sleep to save power. However, if not properly recovered from sleep, the device won't work. It is noticed that some devices doesn't recover properly, so let's add a dump_stack() as a debug option, to allow us to track when this happens.

2008-12-30V4L/DVB (9775): tda8290: fix FM radioMauro Carvalho Chehab
tda8290 were using some random video standard for FM. This results on random errors. Instead, program tda8290 in expert mode, using a configuration near the one specified on NXP datasheet for tda8295 (available on their site). Also, properly display that the device is on radio mode.

2008-12-30V4L/DVB (9774): tda827x: fix returned frequencyMauro Carvalho Chehab
Probably due to a removed code, tda827x were doing some wrong calculus at the returned frequency. I suspect that the original idea were to return the programmed divisor converted into frequency again. However, the current code is sometimes multiplying the programmed frequency by 62500, and, on other cases, like radio, it dividing it by 1000. Instead of doing such math, let's just store the frequency value as requested by the caller module. Cc: Michael Krufky <mkrufky@linuxtv.org> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

download is needed This patch ensures that the xc5000 will have firmware loaded as needed if the part is powered down or reset via gpio from the host. An example of this, in some cases, could be after the system resumes from standby or hibernate modes.

2008-06-26V4L/DVB (8035): tda18271: dont touch EB14 if rf_cal lookup is out of rangeMichael Krufky
The TDA18271HD/C1 rf_cal map lookup is expected to go out of range outside of the frequency window 41 MHz - 61.1 MHz. In these cases, the internal RF tracking filters calibration mechanism is used.

2008-06-26V4L/DVB (8034): tda18271: fix IF notch frequency handlingMichael Krufky
The IF notch bit gets unset when we update the Main Post Div register value, before we have a chance to write the desired IF notch setting to the tuner. Move the IF notch configuration to after we update MPD. Signed-off-by: Michael Krufky <mkrufky@linuxtv.org> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>

If supplied a frequency out of range, the error must be returned to the caller (tda18271c1_rf_tracking_filter_calibration) so that it can decide whether or not to write to register EB14, RFC_CPROG[7:0] Signed-off-by: Michael Krufky <mkrufky@linuxtv.org> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
2008-06-05V4L/DVB (7974): fix MEDIA_TUNER && FW_LOADER build errorIngo Molnar
-tip testing found the following build failure: LD .tmp_vmlinux1 drivers/built-in.o: In function `generic_set_freq': tuner-xc2028.c:(.text+0xbd896): undefined reference to `request_firmware' tuner-xc2028.c:(.text+0xbdd7a): undefined reference to `release_firmware' drivers/built-in.o: In function `xc_load_fw_and_init_tuner': xc5000.c:(.text+0xc68e6): undefined reference to `request_firmware' xc5000.c:(.text+0xc6abe): undefined reference to `release_firmware' with this config: http://redhat.com/~mingo/misc/config-Tue_May_20_18_11_34_CEST_2008.bad the reason is another kconfig tool bug that has to be worked around in the driver's Kconfig file: if FW_LOADER is selected in a second dependency, that is not properly propagated up the dependencies. in this case, FW_LOADER is selected from MEDIA_TUNER_XC2028: config MEDIA_TUNER_XC2028 tristate "XCeive xc2028/xc3028 tuners" depends on VIDEO_MEDIA && I2C depends on HOTPLUG select FW_LOADER which got selected by MEDIA_TUNER: config MEDIA_TUNER tristate default VIDEO_MEDIA && I2C depends on VIDEO_MEDIA && I2C select FW_LOADER if !MEDIA_TUNER_CUSTOMIZE && HOTPLUG but the kconfig tool did not pick up this second-order dependency and allowed CONFIG_FW_LOADER=m to be selected - in which case the build fails. the workaround i found was to move the select of FW_LOADER one level up, so that the buggy kconfig tool can notice it and can act appropriately. This problem can probably be worked around in other ways as well, i went for the minimal fix. Obviously, the kconfig tool should be fixed, it is not reasonable to expect driver authors to do manual dependency resolution (that kconfig itself already does) and uglify the Kconfig files. The kconfig tool did nothing to warn about this situation and did not prevent this faulty .config from being constructed.
