Before, root privileges were only needed to set hardware registers, not to read them. On some hardware, reading from the wrong place at the wrong time can hang the machine. So, to be consistent, root privileges are required to read registers on all hardware. Signed-off-by:

Functions buffer_release() in bttv-driver.c and vbi_buffer_release() in bttv-vbi.c are ending with: bttv_dma_free(&fh->cap,fh->btv,buf); For vbi it seems to be wrong. Both functions should end with: bttv_dma_free(q,fh->btv,buf); Thanks to Peter Schlaf <peter.schlaf@web.de> for pointing this. Signed-off-by:Michael H. Schimek <mschimek@gmx.at> Signed-off-by:

fmtools use VIDIOCSTUNER, with, in turn, calls VIDIOC_S_INPUT on v4l1-compat. So, those ioctls are required for V4L1 to work properly. Signed-off-by: -

v4l1-compat requires those two ioctls to translate VIDIOC[SG]RADIO into V4L2 calls. Signed-off-by: -

Before this patch, vivi were simulating a scatter gather DMA transfer. While this is academic, showing how stuff really works on a real PCI device, this means a non-optimized code. There are only two memory models that vivi implements: 1) kernel alloced memory. This is also used by read() method. On this case, a vmalloc32 buffer is allocated at kernel; 2) userspace allocated memory. This is used by most userspace apps. video-buf will store this pointer. a simple copy_to_user is enough to transfer data. The third memory model scenario supported by video-buf is overlay mode. This model is not implemented on vivi and unlikely to be implemented on newer drivers, since now, most userspace apps do some post-processing (like de-interlacing). After this patch, some cleanups may be done at video-buf.c to avoid allocating pages, when the driver doesn't need a PCI buffer. This is the case of vivi and usb drivers. Signed-off-by: -

The direct register access ioctls were defined as kernel internal only, but they are very useful for debugging hardware from userspace and are used as such. Officially export them. VIDIOC_INT_[SG]_REGISTER is renamed to VIDIOC_DBG_[SG]_REGISTER Definition of ioctl and struct v4l2_register is moved from v4l2-common.h to videodev2.h. Types used in struct v4l2_register are changed to the userspace exportable versions (u32 -> __u32, etc). Use of VIDIOC_DBG_S_REGISTER requires CAP_SYS_ADMIN permission, so move the check into the video_ioctl2() dispatcher so it doesn't need to be duplicated in each driver's call-back function. CAP_SYS_ADMIN check is added to pvrusb2 (which doesn't use video_ioctl2). Signed-off-by:

QT1010: - old qt1010-code totally rewritten and put in own kernel module - same enhancements as my earlier QT1010 125kHz patch - tuner initialization - register 1f calculation - register 20 calculation - register 25 calculation m920x: (MSI Megasky) - use new QT1010 module instead of old code Signed-off-by:

Some cleanups and suggestions from Patrick Boettcher. Dropped the mutex in m9206_rc_query using #if 0, because M9206_CORE, M9206_I2C, M9206_FILTER and M9206_FW can be accessed concurrently. Thanks to both Aapo Tahkola and Patrick Boettcher. Signed-off-by:

Currently, the driver works in bulk mode supporting both USB 2.0 and 1.0 with and without hardware pid filters. The ULi m9205 also supports isochronous transfer mode, but I have dropped support for it because it depends on firmware and does not work on all USB host chips. Further, I have no firmware with remote controller support for this mode. Signed-off-by:

I noticed that udev does not create a symlink for the CinergyT2 remote input device in /dev/input/by-id, which is required if I want to have a unique device name for lircd. The attached patch tries to achive this. However, udev still omits the input device for /dev/input/by-id symlinks. I think something is still not reported correctly. Signed-off-by:
