2009-06-04V4L/pwc - use usb_interface as parent, not usb_deviceMauro Carvalho Chehab
From: Lennart Poettering <mzxreary@0pointer.de> The current code creates a sysfs device path where the video4linux device is child of the usb device itself instead of the interface it belongs to. That is evil and confuses udev. This patch does basically the same thing as Kay's similar patch for the ov511 driver: http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=ce96d0a44a4f8d1bb3dc12b5e98cb688c1bc730d Signed-off-by: Lennart Poettering <mzxreary@0pointer.de> Acked-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2009-06-11v4l: generate KEY_CAMERA instead of BTN_0 key events on input devicesDouglas Schilling Landgraf
From: Lennart Poettering <mzxreary@0pointer.de> A bunch of V4L drivers generate BTN_0 instead of KEY_CAMERA key presses. X11 is able to handle KEY_CAMERA automatically these days while BTN_0 is not treated at all. Thus it would be of big benefit if the camera drivers would consistently generate KEY_CAMERA. Some drivers (uvc) already do, this patch updates the remaining drivers to do the same. I only possess a limited set of webcams, so this isn't tested with all cameras. The patch is rather trivial and compile tested, so I'd say it's still good enough to get merged.

2008-12-30v4l2-ioctl: change to long return type to match unlocked_ioctl.Hans Verkuil
From: Hans Verkuil <hverkuil@xs4all.nl> 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.

2008-12-30v4l2: introduce v4l2_file_operations.Hans Verkuil
From: Hans Verkuil <hverkuil@xs4all.nl> 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.

2008-10-19v4l: use video_device.num instead of minor in video%dHans Verkuil
From: Hans Verkuil <hverkuil@xs4all.nl> 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.

2007-03-21pwc: cisco VT Camera supportMauro Carvalho Chehab
From: Jean Tourrilhes <jt@hpl.hp.com> I have a Cisco VT Camera, and it was just collecting dust. I decided to try connecting it to my Linux box at home. Just a disgression about the product. The Cisco VT Camera is a webcam Cisco sold to work with their IP phone hardware and software. It's mostly useless on Windows, as it interfaces only to Cisco software. You can find some for cheap on eBay... Physically, it's just a Logitech Pro 4000. The only difference with the Pro 4000 is the Cisco logo and that it's grey like the Pro 3000. I believe Cisco is now selling the Cisco VT Camera II, which look to be something else... So, assuming that it was a Pro 4000 inside, I created the little patch attached. I'm new to webcam under Linux, but I managed to get an image from it using xawtv, and the image looked all right, so I consider that a success. The imaged seemed a bit small and I could not get the microphone driver loaded, but I assume it's my lack of experience. Note that I did not try any other type_id, but this one works great.

2007-01-30Remove obsolete alias defines of CONFIG_* settingsTrent Piepho
From: Trent Piepho <xyzzy@speakeasy.org> The out of tree v4l-dvb build system didn't always override the kernel's configuration settings with v4l-dvb's settings correctly. To work around this, makefiles would define some new macro based on the setting of a config variable. e.g. the pwc Makefile would define CONFIG_PWC_DEBUG if CONFIG_USB_PWC_DEBUG (which is defined via Kconfig) was set. The v4l-dvb build system should now always override correctly, and this is no longer necessary. This patch gets ride of these extra defines and just uses the CONFIG_* settings directly.

2006-10-21IRQ: Maintain regs pointer globally rather than passing to IRQ handlersMauro Carvalho Chehab
Kernel-sync: This patch is required to allow compilation of the tree with kernel 2.6.19. This is the original description of the original patch, signed by David Howells <dhowells@redhat.com>: 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. Signed-Off-By: Mauro Carvalho Chehab <mchehab@infradead.org>

2006-10-04USB: Dealias -110 code (more complete)Mauro Carvalho Chehab
From: Mauro Carvalho Chehab <mchehab@infradead.org> Apply the relevant parts of a patch from Pete Zaitcev <zaitcev@redhat.com> kernel-sync: Original description: The purpose of this patch is to split off the case when a device does not reply on the lower level (which is reported by HC hardware), and a case when the device accepted the request, but does not reply at upper level. This redefinition allows to diagnose issues easier, without asking the user if the -110 happened "immediately". The usbmon splits such cases already thanks to its timestamp, but it's not always available. I adjusted all drivers which I found affected (by searching for "urb"). Out of tree drivers may suffer a little bit, but I do not expect much breakage. At worst they may print a few messages. Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
