| mchehab | buxy81: just sent the patches for your Terratec H6 to the linux-media ML...
I opted to split it in two separate patches. The first one adding support to set the eeprom bus and the second one with the new Terratec H6 entry... one question: do you know if are there any revision number on this device? perhaps written on its motherboard also, could you please double-check if those patches are enough to make it work? it would be great if you could test those two patches and reply with a "Tested-by: your name <your@email>" | [11:38] |

| LiquidAcid | hello, i'm currently trying to add dmabuf support to the s5p-mfc v4l2 driver, using code from the tizen tree: https://review.tizen.org/git/?p=platform/kernel/linux-3.10.git;a=commit;h=f7b12027b3dbebc2a937c5a12433477167b7ab66
however the patch seems to be incomplete, i get a iommu pagefault on streaming start my initial investigation suggests that the problem is that buf_init() is only called by v4l2 core when dealing with mmap buffers, and not with dmabuf here's the relevant code in the driver: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/drivers/media/platform/s5p-mfc/s5p_mfc_dec.c#n990 notice that src_bufs[] is only assigned in buf_init(). in dmabuf is used, it is left unitialized, and then used as is in buf_queue() my question: is buf_prepare() the correct call to get the dma address of a buffer into the driver? | [15:44] |

| buxy81 | mchehab: err, i'm so happy with my setup now, i don't wanna ruin it. :D but yes, of course, i'll make a clean build on a fresh raspbian lite system. give me a couple of days on that.
as i'm not that familiar with the whole v4l project, i did not modify anything else in the media_build codebase. | [20:32] |
| and yes, a third thing is required, the firmware file: /lib/firmware/dvb-usb-terratec-htc-stick-drxk.fw | [20:39] | |
