2008-11-11V4L/DVB (9516): cx18: Move DVB buffer transfer handling from irq handler to ↵Andy Walls
work_queue cx18: Move DVB buffer transfer handling from irq handler to work_queue thread. In order to properly lock the epu2cpu mailbox for driver to CX23418 commands, the DVB/TS buffer handling needs to be moved from the IRQ handler and IRQ context to a work queue. This work_queue implmentation is strikingly similar to the ivtv implementation - for better or worse.

The SCB field definitions for Ack IRQ's for mailboxes were inconsistent with the bitmasks being loaded into those SCB fields and the SW2 Ack IRQ handling logic.

2008-11-11V4L/DVB (9492): unplug oops from dvb_frontend_init...Daniel J Blueman
When inadvertently hot-unplugging a WT-220U USB DVB-T receiver with 2.6.24, I was met with an oops [1]. The problem is relevant to 2.6.25/26-rc also. dvb_frontend_init() was called either from re-creation of the kdvb-fe0 thread - seems unlikely, or someone called dvb_frontend_reinitialise(), causing this path in the thread - really unlikely, as I can't find any call-site for it. Either way, quite a number of drivers call dvb_usb_generic_rw() [2] without checking the validity of the relevant member in the dvb_usb_device struct - which had changed. Having dvb_usb_generic_rw() sanity-check and fail (rather than loading from 0x120) seems reasonable defensive programming [3], in light of it being called in this way. The problem with this, is that drivers don't check the return code of the init call [4]. Does it make sense to cook a patch which allows the failure to be propagated back up, or am I missing something else?

2008-11-11V4L/DVB (9357): cx88-dvb: Fix Oops in case i2c bus failed to registerMatthias Schwarzott
There already is an report at kernel bugzilla about this issue: http://bugzilla.kernel.org/show_bug.cgi?id=9455 When enabling extra checks for the i2c-bus of cx88 based cards by loading i2c_algo_bit with bit_test=1 this may trigger an oops when loading cx88_dvb. This is caused by the extra check code that detects that the sda-line is stuck high and thus does not register the i2c-bus. cx88-dvb however does not check if the i2c-bus is valid and just uses core->i2c_adap to attach dvb frontend modules.

Impact: driver could possibly stomp on resources outside of its scope {mchehab@redhat.com: I got two versions of the same patch (identical, except for whitespacing). One authored by Andy Burns and another authored by Suresh Siddha. Due to that, I'm applying the one that has less CodingStyle errors. I'm also adding both comments and the SOB's for both patches, since they are both interesting} Suresh Siddha commented: Alexey Fisher reported: > resource map sanity check conflict: 0xcfeff800 0xcff007ff 0xcfe00000 > 0xcfefffff PCI Bus 0000:01 BAR base is located in the middle of the 4K page and the hardcoded size argument makes the request span two pages causing the conflict. Fix the hard coded size argument in ioremap(). Andy Burns commented: I have already sent this patch on the linux-dvb list, but it didn't get much attention, so re-sending direct, I hope you all don't mind. While attempting to run mythtv in a xen domU, I encountered problems loading the driver for my saa7134 card, with an error from ioremap(). This error was due to the driver allocating an incorrectly sized mmio area, which was trapped by xen's permission checks, but this would go un-noticed on a kernel without xen. My card has a 1K sized mmio area, I've had information that other cards have 2K areas, perhaps others have different sizes, yet the driver always attempts to map 4K. I realise that the granularity of mapping is the page size, which typically would be 4K, but unless the card's base address happens to fall on a 4K boundary (mine does not) then the base+4K will end up spanning two pages, and this is when the error occurs under xen. My patch uses the pci_resource_len macro to determine the size required for the user's particular card, instead of the hardcoded 4K value. I've tested with a couple of printk() inside ioremap() that the start address and size do get rounded to the closest page boundary. With this patch I am able to successfully load the saa7134 driver and run mythtv under xen with my card, subject to correct pollirq settings in case of shared IRQ, I am still seeing occasional DMA panics, which I think are related to swiotlb handling by dom0/domU, usually the panic occurs when changing mux, once tuned to a mux, 12 hour continuous recordings are possible without errors.

2008-11-11V4L/DVB (9346): Optimization: Enable gate in a symmetric/disciplined way,Manu Abraham
rather than implementing different ways leading to confusion. This allows multiple gate_enable/disable's in the tuner_read/write functions, thereby lesser number of I/O operations throughout, eventually leading to better results. As a side effect demods that detect the STOP bit for auto closing of the gate can be avoided, thereby a very minimal gain in disabling the auto detect feature as well.

2008-10-21V4L/DVB (9331): Remove unused inode parameter from video_ioctl2Mauro Carvalho Chehab
inode is never used on video_ioctl2. Remove it and rename the function to __video_ioctl2. This allows its usage directly as a callback at fops.unlocked_ioctl. Since we still need a callback with inode to be used with fops.ioctl, this patch adds video_ioctl2() that is just a call to __video_ioctl2(). Also, this patch adds some comments about video_ioctl2 and __video_ioctl2 usage at v4l2-ioctl.h. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

2008-10-21V4L/DVB (9327): v4l: use video_device.num instead of minor in video%dHans Verkuil
The kernel number of a v4l2 node (e.g. videoX, radioX or vbiX) is now independent of the minor number. So instead of using the minor field of the video_device struct one has to use the num field: this always contains the kernel number of the device node. I forgot about this when I did the v4l2 core change, so this patch converts all drivers that use it in one go. Luckily the change is trivial.

the desired modulation If we are already at the desired modulation, there is no need to reconfigure the demod (at a tuning time cost) Note that this change revealed that although the datasheet says the demod starts out in VSB-8 mode, the first tuning was failing consistently unless we went through the work of setting the registers. So add a field to denote this case so we always do the enable_frontend call, even if the first tuning request is for VSB-8.
