2011-05-10firewire: optimize iso queueing by setting wake only after the last packetClemens Ladisch
When queueing iso packets, the run time is dominated by the two MMIO accesses that set the DMA context's wake bit. Because most drivers submit packets in batches, we can save much time by removing all but the last wakeup. The internal kernel API is changed to require a call to fw_iso_context_queue_flush() after a batch of queued packets. The user space API does not change, so one call to FW_CDEV_IOC_QUEUE_ISO must specify multiple packets to take advantage of this optimization. In my measurements, this patch reduces the time needed to queue fifty skip packets from userspace to one sixth on a 2.5 GHz CPU, or to one third at 800 MHz.

2011-05-10firewire: octlet AT payloads can be stack-allocatedStefan Richter
We do not need slab allocations anymore in order to satisfy streaming DMA mapping constraints, thanks to commit da28947e7e36 "firewire: ohci: avoid separate DMA mapping for small AT payloads". (Besides, the slab-allocated buffers that firewire-core, firewire-sbp2, and firedtv used to provide for 8-byte write and lock requests were still not fully portable since they crossed cacheline boundaries or shared a cacheline with unrelated CPU-accessed data. snd-firewire-lib got this aspect right by using an extra kmalloc/ kfree just for the 8-byte transaction buffer.) This change replaces kmalloc'ed lock transaction scratch buffers in firewire-core, firedtv, and snd-firewire-lib by local stack allocations. Perhaps the most notable result of the change is simpler locking because there is no need to serialize usages of preallocated per-device buffers anymore. Also, allocations and deallocations are simpler. Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de> Acked-by: Clemens Ladisch <clemens@ladisch.de>

2011-05-04[media] V4L: soc-camera: regression fix: calculate .sizeimage in soc_camera.cSergio Aguirre
A recent patch has given individual soc-camera host drivers a possibility to calculate .sizeimage and .bytesperline pixel format fields internally, however, some drivers relied on the core calculating these values for them, following a default algorithm. This patch restores the default calculation for such drivers.

2011-05-04[media] v4l2-subdev: fix broken subdev control enumerationHans Verkuil
The v4l2_subdev_* functions are meant for older V4L2 drivers that do not use the control framework yet. These functions should not be used by subdev_do_ioctl. Most of those backwards compatibility functions are just stubs, but commit 87a0c94ce616b231f3c0bd09d7dbd39d43b0557a actually changed the behavior of v4l2_subdev_queryctrl, so calling that one from subdev_do_ioctl broke the control enumeration in subdev nodes. The fix is simply not to use those compatibility functions in v4l2-subdev.c. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

2011-04-29[media] v4l: make sure drivers supply a zeroed struct v4l2_subdevHerton Ronaldo Krzesinski
Some v4l drivers currently don't initialize their struct v4l2_subdev with zeros, and this is a problem since some of the v4l2 code expects this. One example is the addition of internal_ops in commit 45f6f84, after that we are at risk of random oopses with these drivers when code in v4l2_device_register_subdev tries to dereference sd->internal_ops->*, as can be shown by the report at http://bugs.launchpad.net/bugs/745213 and analysis of its crash at https://lkml.org/lkml/2011/4/1/168 Use kzalloc within problematic drivers to ensure we have a zeroed struct v4l2_subdev.

2011-04-29[media] imon: add conditional locking in change_protocolJarod Wilson
The imon_ir_change_protocol function gets called two different ways, one way is from rc_register_device, for initial protocol selection/setup, and the other is via a userspace-initiated protocol change request, either by direct sysfs prodding or by something like ir-keytable. In the rc_register_device case, the imon context lock is already held, but when initiated from userspace, it is not, so we must acquire it, prior to calling send_packet, which requires that the lock is held. Without this change, there's an easily reproduceable deadlock when another function calls send_packet (such as either of the display write fops) after a userspace-initiated change_protocol. With a lock-debugging-enabled kernel, I was getting this: [ 15.014153] ===================================== [ 15.015048] [ BUG: bad unlock balance detected! ] [ 15.015048] ------------------------------------- [ 15.015048] ir-keytable/773 is trying to release lock (&ictx->lock) at: [ 15.015048] [<ffffffff814c6297>] mutex_unlock+0xe/0x10 [ 15.015048] but there are no more locks to release!

2011-04-19[media] omap3isp: Don't increment node entity use count when poweron failsLaurent Pinchart
When open a device node, all entities part of the same pipeline are powered on. If one of the entities fails to be powered on, the open operations fails. In that case the device node entity use count must not be incremented. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

2011-04-17[media] omap3isp: isp: Reset the ISP when the pipeline can't be stoppedLaurent Pinchart
When a failure to stop a module in the pipeline is detected, the only way to recover is to reset the ISP. However, as other users can be using a different pipeline with other modules, the ISP can't be reset synchronously with the error detection. Mark the ISP as needing a reset when a failure to stop a pipeline is detected, and reset the ISP when the last user releases the last reference to the ISP. Modify the omap3isp_pipeline_set_stream() function to record the new ISP pipeline state only when no error occurs, except when stopping the pipeline in which case the pipeline is still marked as stopped.

2011-04-17[media] omap3isp: resizer: Use 4-tap mode equations when the ratio is <= 512Laurent Pinchart
As the number of phases/taps, used to select the correct equations to compute the ratio, depends on the ratio, start with the 7-tap mode equations to compute an approximation of the ratio, and switch to the 4-tap mode equations if the approximation is lower than or equal to 512.
