2007-02-24Improve chip matching in v4l2_register for VIDIOC_DBG_G/S_REGISTERHans Verkuil
From: Hans Verkuil <hverkuil@xs4all.nl> The chip matching in struct v4l2_register was rather primitive. It could not be extended to other busses besides i2c and it lacked a way to differentiate between two i2c chips driven by the same driver on one board (e.g. a PVR500 with two tuner chips, one for analog TV and one for radio). It has now been improved making it much more powerful. Signed-off-by: Hans Verkuil <hverkuil@xs4all.nl> CC: Mike Isely <isely@isely.net> CC: Trent Piepho <xyzzy@speakeasy.org>
2007-02-21Backport of git changeset cd354f1ae75e6466a7e31b727faede57a1f89ca5Mauro Carvalho Chehab
From: Mauro Carvalho Chehab <mchehab@infradead.org> Backport a changeset from Schmielau <tim@physik3.uni-rostock.de> that removes uneeded includes for linux/sched.h Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
2007-02-21Backport: make file_operations constMauro Carvalho Chehab
From: Mauro Carvalho Chehab <mchehab@infradead.org> Backport a kernel patch by Arjan van de Ven <arjan@linux.intel.com> that made all file_operations instances const. Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
2007-02-19compat: Add compat code for vm_insert_page()Trent Piepho
From: Trent Piepho <xyzzy@speakeasy.org> Add an inline versin of vm_insert_page() that uses remap_pfn_range() to compat.h. Remove compat code from em28xx-video.c, sn9c102_core.c, and usbvision-video.c since compat.h is now doing the same thing. USB_ZC0301, USB_ET61X251, and USB_ZR364XX will now compile under 2.6.12.

2007-02-07Usbvision: set alternate interface modificationMauro Carvalho Chehab
From: Thierry MERLE <thierry.merle@free.fr> - usb alternate selection modified to get the biggest endpoint packet size. - fix sysfs get values for brightness/contrast/hue/saturation Signed-off-by: Thierry MERLE <thierry.merle@free.fr> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
2007-02-07Usbvision: dynamic allocation for framesMauro Carvalho Chehab
From: Thierry MERLE <thierry.merle@free.fr> - fix decoder route output - dynamic frame buffer allocation Signed-off-by: Thierry MERLE <thierry.merle@free.fr> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
2007-01-30Add checks for CAP_SYS_ADMIN to VIDIOC_DBG_G_REGISTERTrent Piepho
From: Trent Piepho <xyzzy@speakeasy.org> 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: Trent Piepho <xyzzy@speakeasy.org>
2007-01-23Make VIDIOC_INT_[SG]_REGISTER ioctls no longer internal onlyTrent Piepho
From: Trent Piepho <xyzzy@speakeasy.org> 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: Trent Piepho <xyzzy@speakeasy.org>
2007-01-07Improves some USBVision info messagesMauro Carvalho Chehab
From: Dwaine Garden <dwainegarden@rogers.com> Replaces the info statements with printk(KERN_INFO statements. This will cut down on the useless information which is showing up in the kernel messages log file. Signed-off-by: Dwaine P.

2006-12-29Fix the frame->grabstate update in read() entry point.Mauro Carvalho Chehab
From: Thierry MERLE <thierry.merle@free.fr> The Coverity checker spotted that in usbvision_v4l2_read(), the variable "frmx" is never assigned any value different from -1, but it's used an an array index in "usbvision->frame[frmx]". Thanks to Adrian Bunk <bunk@stusta.de> for warning about that. Signed-off-by: Thierry MERLE <thierry.merle@free.fr> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
2006-12-17Fixes compilation when CONFIG_V4L1_COMPAT is not selectedMauro Carvalho Chehab
From: Dwaine Garden<DwaineGarden@rogers.com> - SYSFS: Replaced all to_video_device(cd), video_device_create_file, video_device_remove_file and add the proper checks at create_file - Converted old norm values to V4L2 ones. - Robustness on sysfs hue/contrast/saturation queries. Additional check in order to return 0 if the driver is not opened. - Clean up of white spaces in usbvision.h This patch merges two fixes by Thierry MERLE and Mauro Chehab, and adds additional checks.
