| | | | | | | | | | | | | | | | | | | | | | Rather than loading firmware specific for the xtal frequency, just use the standard firmware and set the xtal frequency after firmware upload. The modified firmware will never be released, so we're better off merging this now rather than waiting for v3.5.

| * [media] dvb_frontend: Fix a regression when switching back to DVB-SMauro Carvalho Chehab2012-04-181-1/+24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There are some softwares (Kaffeine and likely xine) that uses a DVBv5 call to switch to DVB-S2, but expects that a DVBv3 call to switch back to DVB-S. Well, this is not right, as a DVBv3 call doesn't know anything about delivery systems. However, as, by accident, this used to work, we need to restore its behavior, in order to avoid regressions with those softwares.

For whatever unknown reason, xine (and xine-lib clients) wants that the frontend to tell what frequency he is using even before the PLL lock (or at least, it expects a non-zero frequency). On DVB, the frequency is only actually known after a frequency zig-zag seek, done by the DVB core. Anyway, the fix was trivial. That solves Fedora BZ#808871. - ivtv: fix a regression when selecting the language channel - uvc: fix a race-related crash - it913x: fixes firmware loading - two trivial patches (a dependency issue at a radio driver at sound Kconfig, and a warning fix on dvb). * 'v4l_for_linus' of git://git.kernel.org/pub/scm/linux/kernel/git/mchehab/linux-media: [media] uvcvideo: Fix race-related crash in uvc_video_clock_update() [media] Drivers/media/radio: Fix build error [media] dvb_frontend: fix compiler warning [media] it913x: fix firmware loading errors [media] ivtv: Fix AUDIO_(BILINGUAL_)CHANNEL_SELECT regression [media] dvb_frontend: regression fix: userspace ABI broken for xine
| * [media] uvcvideo: Fix race-related crash in uvc_video_clock_update()Laurent Pinchart2012-04-091-18/+32
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The driver frees the clock samples buffer before stopping the video buffers queue. If a DQBUF call arrives in-between, uvc_video_clock_update() will be called with a NULL clock samples buffer, leading to a crash. This occurs very frequently when using the webcam with the flash browser plugin. Move clock initialization/cleanup to uvc_video_enable() in order to free the clock samples buffer after the queue is stopped. Make sure the clock is reset at resume time to avoid miscalculating timestamps.

| * [media] dvb_frontend: regression fix: userspace ABI broken for xineChris Rankin2012-04-091-0/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The commit e399ce77e6e has broken the DVB ABI for xine: The problem is that xine is expecting every event after a successful FE_SET_FRONTEND ioctl to have a non-zero frequency parameter, regardless of whether the tuning process has LOCKed yet. What used to happen is that the events inherited the initial tuning parameters from the FE_SET_FRONTEND call. However, the fepriv->parameters_out struct is now not initialised until the status contains the FE_HAS_LOCK bit. You might argue that this behaviour is intentional, except that if an application other than xine uses the DVB adapter and manages to set the parameters_out.frequency field to something other than zero, then xine no longer has any problems until either the adapter is replugged or the kernel modules reloaded. This can only mean that the fepriv->parameters_out struct still contains the (stale) tuning information from the previous application.

I've built all the working defconfigs from all the arches that I can and made sure that they don't break. The reason for these patches is that I recently encountered a circular dependency problem that came about when I produced some patches to optimise get_order() by rewriting it to use ilog2(). This uses bitops - and on the SH arch asm/bitops.h drags in asm-generic/get_order.h by a circuituous route involving asm/system.h. The main difficulty seems to be asm/system.h. It holds a number of low level bits with no/few dependencies that are commonly used (eg. memory barriers) and a number of bits with more dependencies that aren't used in many places (eg. switch_to()). These patches break asm/system.h up into the following core pieces: (1) asm/barrier.h Move memory barriers here. This already done for MIPS and Alpha. (2) asm/switch_to.h Move switch_to() and related stuff here. (3) asm/exec.h Move arch_align_stack() here. Other process execution related bits could perhaps go here from asm/processor.h. (4) asm/cmpxchg.h Move xchg() and cmpxchg() here as they're full word atomic ops and frequently used by atomic_xchg() and atomic_cmpxchg(). (5) asm/bug.h Move die() and related bits. (6) asm/auxvec.h Move AT_VECTOR_SIZE_ARCH here. Other arch headers are created as needed on a per-arch basis." Fixed up some conflicts from other header file cleanups and moving code around that has happened in the meantime, so David's testing is somewhat weakened by that.

To account for this, we must hardcode the frontend configuration to use the same IF frequency configuration for both revisions of the device. 6MHz DVB-T is unaffected by this issue, as the recommended IF Frequency configuration for 6MHz DVB-T is the same on both c1 and c2 revisions of the tda18271 tuner.

That notwithstanding, the driver did so dink, resulting in "green frame" captures and the death of the system in random, spectacular ways. Move the tweaking of C1_DESC_ENA to the same function that sets the descriptor so we know that we'll never try to set a descriptor while that bit is set.

So a 40ms timeout is not adequate; use 150ms instead. Also make sure we don't leave the DMA_ACTIVE flag set once things are down.
