[media] vb2: fix VBI/poll regression

2014-09-21T23:57:30Z

The recent conversion of saa7134 to vb2 unconvered a poll() bug that broke the teletext applications alevt and mtt. These applications expect that calling poll() without having called VIDIOC_STREAMON will cause poll() to return POLLERR. That did not happen in vb2. This patch fixes that behavior. It also fixes what should happen when poll() is called when STREAMON is called but no buffers have been queued. In that case poll() will also return POLLERR, but only for capture queues since output queues will always return POLLOUT anyway in that situation. This brings the vb2 behavior in line with the old videobuf behavior. Signed-off-by: Hans Verkuil Acked-by: Laurent Pinchart Signed-off-by: Mauro Carvalho Chehab

[media] videobuf2-core.h: fix comment

2014-09-21T23:45:23Z

The comment for start_streaming that tells the developer with which vb2 state buffers should be returned to vb2 gave the wrong state. Very confusing. Signed-off-by: Hans Verkuil Acked-by: Laurent Pinchart Signed-off-by: Mauro Carvalho Chehab

[media] v4l2: blackfin: select proper pinctrl state in ppi_set_params if CONFIG_PINCTRL is enabled

2014-07-26T20:15:16Z

Multiple pinctrl states are defined for 8, 16 and 24 data pin groups in PPI peripheral. The driver should select correct group before set up further PPI parameters. Signed-off-by: Sonic Zhang Acked-by: Scott Jiang Signed-off-by: Mauro Carvalho Chehab

[media] vmalloc_sg: make sure all pages in vmalloc area are really DMA-ready

2014-07-26T14:33:15Z

Patch originally written by Konrad. Rebased on current linux media tree. Under Xen, vmalloc_32() isn't guaranteed to return pages which are really under 4G in machine physical addresses (only in virtual pseudo-physical addresses). To work around this, implement a vmalloc variant which allocates each page with dma_alloc_coherent() to guarantee that each page is suitable for the device in question.

[media] rc-core: don't use dynamic_pr_debug for IR_dprintk()

2014-07-26T02:40:06Z

The hole point of IR_dprintk() is that, once a level is given at debug parameter, all enabled IR parsers will show their debug messages. While converting it to dynamic_printk might be a good idea, right now it just makes very hard to debug the drivers, as one needs to both pass debug=1 or debug=2 to rc-core and to use the dynamic printk to enable all the desired lines. That doesn't make sense! So, revert to the old way, as a single line is changed, and the debug parameter will now work as expected. Signed-off-by: Mauro Carvalho Chehab

[media] v4l2-ctrls: add new RDS TX controls

2014-07-25T22:26:14Z

The si4713 supports several RDS features not yet implemented in the driver. This patch adds the missing RDS functionality to the list of RDS controls. The ALT_FREQS control is a compound control containing an array of up to 25 (the maximum according to the RDS standard) frequencies. To support that the V4L2_CTRL_TYPE_U32 was added.

[media] vb2: fix videobuf2-core.h comments

2014-07-25T22:19:35Z

A lot of work was done in vb2 to regulate how drivers and the vb2 core handle buffer ownership, but inexplicably the videobuf2-core.h comments were never updated. Do so now. The same was true for the replacement of the -ENOBUFS mechanism by the min_buffers_needed field. Signed-off-by: Hans Verkuil Signed-off-by: Mauro Carvalho Chehab
