* V4L/DVB (5869): Add check for valid control ID to v4l2_ctrl_next.Hans Verkuil2007-07-201-5/+14
| | | | | | | | | If v4l2_ctrl_next is called without the V4L2_CTRL_FLAG_NEXT_CTRL then it should check whether the passed control ID is valid and return 0 if it isn't. Otherwise a for-loop over the control IDs will never end. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
* V4L/DVB (5866): ivtv: fix DMA timeout when capturing VBI + another streamHans Verkuil2007-07-201-2/+5
| | | | | | | | | | | | The VBI DMA is handled in a special way and is marked with a bit. However, that bit was set at the wrong time and could be cleared by mistake if a PCM (or other) DMA request would arrive before the VBI DMA was completed. So on completion of the VBI DMA the driver no longer knew that that DMA transfer was for VBI data. And this in turn caused havoc with the card's DMA engine.

| | | | | | | | | | | | | | | | | | | | | | | | | | | The kvm mmu uses page->private on shadow page tables; so does slub, and an oops result.

This causes hangs starting X on guest smp. Fix by making the functions (and resultant tail in the mmu) non-vcpu-specific. Unfortunately this reduces the efficiency of the mmu object cache a bit.

The problem shows up when booting a newer smp Linux kernel, where the trampoline page (which is in real mode, which uses the same shadow pages as large pages) is using the same mapping as a kernel data page, which is mapped using nx, causing kvm to spin on that page.

This results in the kernel waking up around once every couple of milliseconds to process them, making it almost impossible to spend any significant amount of time in C3 state on a dynamic HZ kernel. Sending the mode initialization code makes the device shut up until it's touched again. This patch does so after receiving 10 packets with no interesting content.

This patch adds support for an optional settling delay time, so that two consecutive samples will be taken with the specified delay time apart. This ensures that the chip won't be deselected, so the noise won't appear. Filtering can still be done, but will have less work to do since each time a new sample is taken the same delay applies.

Xbox360 pad has four leds, which form a circle. Unfortunately the leds can't be controlled independently and can only display a predefined set of patterns (for example one is turned on wile others are off or a rotating pattern - 1-2-3-4). To activate a pattern one needs to send a specific command to the device (see http://www.free60.org/wiki/Gamepad). Led subsystem allows us to set brightness, but there is nothing like brightness on this device. So brightness is actually interpreted as the command (only values between 0 and 14 are accepted).

However, in some cases (especially with PMP), it's unclear which commands are affected by the error condition and although aborting all in-flight commands work, it isn't optimal and may cause unnecessary disruption. On the other hand, waiting for in-flight commands to drain themselves can take up to 30seconds. This patch implements EH fast drain to handle such situations. It gives in-flight commands some time to finish up but doesn't wait for too long. After EH is scheduled, fast drain timer is started and if no other completion occurs in ATA_EH_FASTDRAIN_INTERVAL all in-flight commands are aborted. If any completion occurred in the interval, the port is given another interval to finish up itself. Currently ATA_EH_FASTDRAIN_INTERVAL is 3 secs which should be enough for finishing up most commands. Signed-off-by: Tejun Heo <htejun@gmail.com> Signed-off-by: Jeff Garzik <jeff@garzik.org>
