2007-07-30V4L/DVB (5939): dvb-pll: make struct dvb_pll_fcv1236d staticAdrian Bunk
The fcv1236d support patch was created before the "dvb: remove static dependencies on dvb-pll" patch was applied, but the fcv1236d patch didn't get merged until after the fact. struct dvb_pll_fcv1236d can become static.

2007-07-18V4L/DVB (5777): Dvb-pll digitv dvb-usb: Eliminate last user of dvb_pll_configureTrent Piepho
The last user of dvb_pll_configure was the dvb-usb function dvb_usb_tuner_calc_regs(), which was nothing more than a wrapper around dvb_pll_configure(). It's just a copy of the functionality provided by the tuner_ops calc_regs method, and can be deleted. There were two users of dvb_usb_tuner_calc_regs(). One was dvb_usb_tuner_set_params_i2c(), which is converted to use fe->ops.tuner_ops.calc_regs(). The other was the digitv driver. This driver can use one of two demods, mt352 or nxt6000. For the mt352, the driver would set tuner_ops.calc_regs to dvb_usb_tuner_calc_regs(). We can just attach dvb_pll and use the tuner_ops.calc_regs() provided by that module. For the nxt600, the driver would set tuner_ops.set_params to digitv_nxt6000_tuner_set_params. That function would in turn use dvb_usb_tuner_calc_regs(). We convert it to use tuner_ops.calc_regs() instead, and use dvb_pll_attach. The digitv_tuner_attach() needs to know which frontend was attached by digitv_frontend_attach(), since the nxt6000 needs tuner_ops.set_params() to be overridden with digitv_nxt6000_tuner_set_params(). So, to do this a digitv_state that says which frontend was used is added to the dvb_usb_device private state field.

2007-07-18V4L/DVB (5636): Integrate all users of the fmd1216 tuner with dvb-pllTrent Piepho
Enhance the dvb-pll definition of the fmd1216 tuner by adding an init sequence and a sleep sequence. The init sequence sets the AGC control register to 0xa0, selecting the fast time constant and 112 dBuV take-over point. This the recommended value for DVB-T operation. The sleep sequence sets bit P4 (which is believed to turn the analog demodulator on), turns off the tuning voltage, and sets the AGC control register to 0x60 (external AGC voltage, the recommended value for analog operation). The existing dvb-pll users in the cx88 driver, listed below, will gain these init and sleep sequences. CX88_BOARD_HAUPPAUGE_HVR1100 Hauppauge WinTV-HVR1100 DVB-T/Hybrid CX88_BOARD_HAUPPAUGE_HVR1100LP Hauppauge WinTV-HVR1100 DVB-T/Hybrid (Low Profi CX88_BOARD_WINFAST_DTV2000H WinFast DTV2000 H CX88_BOARD_HAUPPAUGE_HVR3000 Hauppauge WinTV-HVR3000 TriMode Analog/DVB-S/DV CX88_BOARD_HAUPPAUGE_HVR1300 Hauppauge WinTV-HVR1300 DVB-T/Hybrid MPEG Encod This non-dvb-pll user in the cx88 driver should only gain the sleep sequence, as it already had an equivalent init sequence. The non-dvb-pll code for this user is removed. X88_BOARD_DNTV_LIVE_DVB_T_PRO digitalnow DNTV Live! DVB-T Pro In these saa7134 driver, these non-dvb-pll users are converted to use dvb-pll: SAA7134_BOARD_MD7134 Medion 7134 SAA7134_BOARD_ASUS_EUROPA2_HYBRID Asus Europa2 OEM The saa7134 functions philips_fmd1216_tuner_init(), philips_fmd1216_tuner_sleep(), and philips_fmd1216_tuner_set_params() are deleted and the dvb-pll versions are used. This should result in equivalent sleep, init, and tuning sequences being sent to the tuner. For the cxusb driver, only one board is effected: USB_PID_MEDION_MD95700 Medion MD95700 This board used dvb_usb_tuner_init_i2c() and dvb_usb_tuner_set_params_i2c() for init and tuning, respectively. These functions are effectively the same as the dvb-pll versions. They call a tuner pass control function defined at the dvb-usb level, but this does not matter, as this card does not have a tuner pass control function (only the dib3000mb does). This board will gain the sleep sequence, while init and tuning should be unchanged.

2007-07-17Freezer: make kernel threads nonfreezable by defaultRafael J. Wysocki
Currently, the freezer treats all tasks as freezable, except for the kernel threads that explicitly set the PF_NOFREEZE flag for themselves. This approach is problematic, since it requires every kernel thread to either set PF_NOFREEZE explicitly, or call try_to_freeze(), even if it doesn't care for the freezing of tasks at all. It seems better to only require the kernel threads that want to or need to be frozen to use some freezer-related code and to remove any freezer-related code from the other (nonfreezable) kernel threads, which is done in this patch. The patch causes all kernel threads to be nonfreezable by default (ie. to have PF_NOFREEZE set by default) and introduces the set_freezable() function that should be called by the freezable kernel threads in order to unset PF_NOFREEZE. It also makes all of the currently freezable kernel threads call set_freezable(), so it shouldn't cause any (intentional) change of behaviour to appear. Additionally, it updates documentation to describe the freezing of tasks more accurately. [akpm@linux-foundation.org: build fixes] Signed-off-by: Rafael J.

2007-07-03V4L/DVB (5818): CinergyT2: fix flush_workqueue() vs work->func() deadlockOleg Nesterov
Spotted and tested by Thomas Sattler <tsattler@gmx.de>. cinergyT2.c does cancel_delayed_work() + flush_scheduled_work() while holding cinergyt2->sem. This leads to deadlock because work->func() needs the same mutex to complete. Another bug is that this code in fact can't reliably stop the re-arming delayed_work. Convert this code to use cancel_rearming_delayed_work() and move it out of ->sem. Another mutex, ->wq_sem, was added to protect against the concurrent open/resume. This patch is a horrible hack to fix the lockup which happens in practice. As Dmitry Torokhov pointed out this driver has other problems and needs further changes.

2007-06-28Fix Kconfig dependency problems wrt boolean menuconfigsTrent Piepho
If one has a dependency chain (tristate)FOO depends on (bool)BAR depends on (tristate)BAZ, build problems will result. If BAZ=m, then BAR can be set y, which allows FOO=y. It's possible to have FOO=y && BAZ=m, which wouldn't be allowed if FOO depended directly on BAZ. In effect, the bool promotes the tristate from m to y. This ends up causing a problem with several menuconfigs that look like: menuconfig BAR bool depends on BAZ [tristate] if BAR config FOO tristate endif The solution used here is to add the dependencies of BAR to the if statement, so that items in the if block will gain a direct non-bool-promoted dependency on BAZ. This is how it would work if a menu was used instead of an if block. Signed-off-by: Trent Piepho <xyzzy@speakeasy.org> Acked-by: Mauro Carvalho Chehab <mchehab@infradead.org> Cc: "David S.

2007-06-08V4L/DVB (5761): Fix broken b2c2 dependency on non x86 architecturesMauro Carvalho Chehab
This patch moves flexcop-dma (currently used only by flexcop-pci) to b2c2-flexcop-pci module, that is dependent on CONFIG_PCI, fixing the bug as reported by Geert Uytterhoeven <geert@linux-m68k.org>: drivers/media/dvb/b2c2/flexcop-dma.c uses the PCI DMA API, but DVB_B2C2_FLEXCOP doesn't depend on PCI, causing the following problem on PCI-less systems: | linux/drivers/media/dvb/b2c2/flexcop-dma.c:20: warning: implicit declaration of function 'pci_alloc_consistent' | linux/drivers/media/dvb/b2c2/flexcop-dma.c:20: warning: implicit declaration of function 'pci_alloc_consistent' Apparently this is the flexcop DMA core, which is used by both DVB_B2C2_FLEXCOP_PCI and DVB_B2C2_FLEXCOP_USB.

2007-06-08V4L/DVB (5716): Tda10086,tda826x: fix tuning, STR/SNR valuesOliver Endriss
Several people reported unreliable reception with the current driver. Furthermore, STR and SNR values seem to be inverted. This fix is based on a patch posted by Hartmut Hackman. Thanks to Helmut Auer for testing and helping to optimize the patch. tda826x: - set baseband cut-off to 19 MHz tda10086: - change the parameters of the carrier recovery loop - toggle register 0x02 between 0x35 (tuning) and 0x00 (locked) - invert STR and SNR values Signed-off-by: Oliver Endriss <o.endriss@gmx.de> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
