2009-09-19V4L/DVB (12540): v4l: simplify v4l2_i2c_new_subdev and friendsHans Verkuil
Rewrite v4l2_i2c_new_subdev as a simplified version of v4l2_i2c_new_subdev_cfg and remove v4l2_i2c_new_probed_subdev and v4l2_i2c_new_probed_subdev_addr. This simplifies this API substantially.

2009-01-29V4L/DVB (10219): saa7134: Prevent Oops due to stale IRQ status when enabling ↵Andy Walls
interrupts When enabling a shared IRQ line, then saa7134_irq handler could be invoked before the driver had completely set up internal structures, due to a shared interrupt line firing. Clear the saa7134 interrupt status reg, before requesting the irq line, so that stale IRQ status isn't processed before the internal structures are set up. Marcin Slusarz recently brought this Oops to the attention of the v4l-dvb lists and provided an initial analysis by investigating reports found here: http://kerneloops.org/guilty.php?guilty=mute_input_7133&version=2.6.27-release&start=1802240&end=1835007&class=oops Reported-by: Marcin Slusarz <marcin.slusarz@gmail.com> Signed-off-by: Andy Walls <awalls@radix.net> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2008-11-11V4L/DVB (9356): [PATCH] saa7134: fix resource map sanity check conflictSuresh Siddha
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.

2008-10-21V4L/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.

2008-07-26V4L/DVB (8496): saa7134: Copy tuner data earlier in init to avoid ↵Simon Arlott
overwriting manual tuner type When saa7134_board_init2 runs, it immediately overwrites the current value (set earlier from module parameter) of tuner_type with the static values, and then does autodetection. This patch moves the tuner_addr copy to earlier in saa7134_initdev and removes the tuner_type copy from saa7134_board_init2. Autodetection could still potentially change to the wrong tuner type, but it is now possible to override the default type for the card again. My card's tuner is configured with autodetection from eeprom, so I don't need to manually set the tuner. I've checked that the autodetection still works for my card.

2007-12-11V4L/DVB (6690): saa7134: fix ignored interruptsHeikki Lindholm
The saa7134 video driver starts dropping frames when used together with the saa7134-alsa driver. Frames are dropped because when an audio event is waiting the driver simply ignores the interrupt and passes it on to the saa7134-alsa interrupt handler. The alsa interrupt handler in turn acknowledges all types of events thus clearing the pending video events as well. Fix by only masking out the audio event in the video interrupt handler and by only acknowledging the audio event in the alsa driver.
