* V4L/DVB (13550): v4l: Use the new video_device_node_name functionLaurent Pinchart2009-12-161-2/+2
| | | | | | | | | | Fix all device drivers to use the new video_device_node_name function. This also strips kernel log messages from the "/dev/" prefix, has the device node location is a userspace policy decision unknown to the kernel.

* V4L/DVB (10138): v4l2-ioctl: change to long return type to match unlocked_ioctl.Hans Verkuil2009-01-021-3/+3
| | | | | | | | | | | | | Since internal to v4l2 the ioctl prototype is the same regardless of it being called through .ioctl or .unlocked_ioctl, we need to convert it all to the long return type of unlocked_ioctl. Thanks to Jean-Francois Moine for posting an initial patch for this and thus bringing it to our attention.

* V4L/DVB (10135): v4l2: introduce v4l2_file_operations.Hans Verkuil2009-01-021-11/+7
| | | | | | | | | | | | | | | | Introduce a struct v4l2_file_operations for v4l2 drivers. Remove the unnecessary inode argument. Move compat32 handling (and llseek) into the v4l2-dev core: this is now handled in the v4l2 core and no longer in the drivers themselves. Note that this changeset reverts an earlier patch that changed the return type of__video_ioctl2 from int to long. This change will be reinstated later in a much improved version.

* V4L/DVB (9503): v4l: remove inode argument from video_usercopyHans Verkuil2008-12-291-3/+2
| | | | | | | | | The inode argument was never used. Removing it from video_usercopy brings the function pointer type of video_usercopy in line with similar v4l2 functions, thus simplifying several drivers.

* V4L/DVB (9327): v4l: use video_device.num instead of minor in video%dHans Verkuil2008-10-211-1/+1
| | | | | | | | | | | | | | | | | | | | | | | The kernel number of a v4l2 node (e.g. videoX, radioX or vbiX) is now independent of the minor number. So instead of using the minor field of the video_device struct one has to use the num field: this always contains the kernel number of the device node. I forgot about this when I did the v4l2 core change, so this patch converts all drivers that use it in one go. Luckily the change is trivial.

* [PATCH] mark struct file_operations const 4Arjan van de Ven2007-02-121-1/+1
| | | | | | | | | | | | Many struct file_operations in the kernel can be "const". Marking them const moves these to the .rodata section, which avoids false sharing with potential dirty data. In addition it'll catch accidental writes at compile time to these shared resources.

* IRQ: Maintain regs pointer globally rather than passing to IRQ handlersDavid Howells2006-10-051-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Maintain a per-CPU global "struct pt_regs *" variable which can be used instead of passing regs around manually through all ~1800 interrupt handlers in the Linux kernel. The regs pointer is used in few places, but it potentially costs both stack space and code to pass it around. On the FRV arch, removing the regs parameter from all the genirq function results in a 20% speed up of the IRQ exit path (ie: from leaving timer_interrupt() to leaving do_IRQ()). Where appropriate, an arch may override the generic storage facility and do something different with the variable. On FRV, for instance, the address is maintained in GR28 at all times inside the kernel as part of general exception handling. Having looked over the code, it appears that the parameter may be handed down through up to twenty or so layers of functions. Consider a USB character device attached to a USB hub, attached to a USB controller that posts its interrupts through a cascaded auxiliary interrupt controller. A character device driver may want to pass regs to the sysrq handler through the input layer which adds another few layers of parameter passing. I've build this code with allyesconfig for x86_64 and i386. I've runtested the main part of the code on FRV and i386, though I can't test most of the drivers. I've also done partial conversion for powerpc and MIPS - these at least compile with minimal configurations. This will affect all archs. Mostly the changes should be relatively easy. Take do_IRQ(), store the regs pointer at the beginning, saving the old one: struct pt_regs *old_regs = set_irq_regs(regs); And put the old one back at the end: set_irq_regs(old_regs); Don't pass regs through to generic_handle_irq() or __do_IRQ(). In timer_interrupt(), this sort of change will be necessary: - update_process_times(user_mode(regs)); - profile_tick(CPU_PROFILING, regs); + update_process_times(user_mode(get_irq_regs())); + profile_tick(CPU_PROFILING); I'd like to move update_process_times()'s use of get_irq_regs() into itself, except that i386, alone of the archs, uses something other than user_mode(). Some notes on the interrupt handling in the drivers: (*) input_dev() is now gone entirely. The regs pointer is no longer stored in the input_dev struct. (*) finish_unlinks() in drivers/usb/host/ohci-q.c needs checking. It does something different depending on whether it's been supplied with a regs pointer or not. (*) Various IRQ handler function pointers have been moved to type irq_handler_t.

* V4L/DVB (3599b): Whitespace cleanups under drivers/mediaMauro Carvalho Chehab2006-03-251-21/+21

* V4L/DVB (3599a): Move drivers/usb/media to drivers/media/videoMauro Carvalho Chehab2006-03-251-0/+2190
Because of historic reasons, there are two separate directories with V4L stuff. Most drivers are located at driver/media/video. However, some code for USB Webcams were inserted under drivers/usb/media. This makes difficult for module authors to know were things should be. Also, makes Kconfig menu confusing for normal users. This patch moves all V4L content under drivers/usb/media to drivers/media/video, and fixes Kconfig/Makefile entries.
