* [media] omap24xxcam: Fix compilationThomas Weber2011-03-211-0/+1
| | | | | | | | | | | | | | | | | | Add linux/sched.h because of missing declaration of TASK_NORMAL. This patch fixes the following error: drivers/media/video/omap24xxcam.c: In function 'omap24xxcam_vbq_complete': drivers/media/video/omap24xxcam.c:415: error: 'TASK_NORMAL' undeclared (first use in this function) drivers/media/video/omap24xxcam.c:415: error: (Each undeclared identifier is reported only once drivers/media/video/omap24xxcam.c:415: error: for each function it appears in.)

* media/video: don't use flush_scheduled_work()Tejun Heo2010-12-241-3/+3
| | | | | | | | | | | | | | | | | | | This patch converts the remaining users of flush_scheduled_work() in media/video. * bttv-input.c and cx23885-input.c don't use workqueue at all. No need to flush. * Make omap24xxcam.c and saa7134-empress.c flush the used work directly. * In fd_defio.c, replace cancel_delayed_work() + flush_scheduled_work() with cancel_delayed_work_sync(). While at it, replace the deprecated cancel_rearming_delayed_work() with cancel_delayed_work_sync(). Signed-off-by: Tejun Heo <tj@kernel.org> Cc: Mauro Carvalho Chehab <mchehab@infradead.org>
* V4L/DVB: videobuf: add ext_lock argument to the queue init functions (part 2)Hans Verkuil2010-10-211-1/+1

* V4L/DVB: videobuf: add queue argument to videobuf_waiton()Hans Verkuil2010-10-211-1/+1
| | | | | | | | | | | | | | | | videobuf_waiton() must unlock and relock ext_lock if it has to wait. For that to happen it needs the videobuf_queue pointer. Don't attempt to unlock/relock q->ext_lock unless it was locked in the first place. vb->state has to be protected by a spinlock to be safe. This patch is based on code from Mauro Carvalho Chehab <mchehab@redhat.com>.

* V4L/DVB: videobuf: Remove the videobuf_sg_dma_map/unmap functionsLaurent Pinchart2010-08-021-1/+1
| | | | | | | | | | Instead of creating dirty wrappers around videobuf_dma_map/unmap that create a dummy videobuf_queue structure, modify videobuf_dma_map/unmap to take a device pointer argument and use it directly. The videobuf_sg_dma_map/unmap then become unused and can be removed. Signed-off-by: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
* V4L/DVB: V4L2: Replace loops for finding max buffers in VIDIOC_REQBUFS callbacksAndreas Bombe2010-05-191-2/+2
| | | | | | | | | | | | | Due to obvious copy and paste coding a number of video capture drivers which implement a limit on the buffer memory decremented the user supplied buffer count in a while loop until it reaches an acceptable value. This is a silly thing to do when the maximum value can be directly computed. Signed-off-by: Andreas Bombe <aeb@debian.org> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

* include cleanup: Update gfp.h and slab.h includes to prepare for breaking ↵Tejun Heo2010-03-301-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | implicit slab.h inclusion from percpu.h percpu.h is included by sched.h and module.h and thus ends up being included when building most .c files. percpu.h includes slab.h which in turn includes gfp.h making everything defined by the two files universally available and complicating inclusion dependencies. percpu.h -> slab.h dependency is about to be removed. Prepare for this change by updating users of gfp and slab facilities include those headers directly instead of assuming availability. As this conversion needs to touch large number of source files, the following script is used as the basis of conversion. http://userweb.kernel.org/~tj/misc/slabh-sweep.py The script does the followings. * Scan files for gfp and slab usages and update includes such that only the necessary includes are there. ie. if only gfp is used, gfp.h, if slab is used, slab.h. * When the script inserts a new include, it looks at the include blocks and try to put the new include such that its order conforms to its surrounding. It's put in the include block which contains core kernel includes, in the same order that the rest are ordered - alphabetical, Christmas tree, rev-Xmas-tree or at the end if there doesn't seem to be any matching order. * If the script can't find a place to put a new include (mostly because the file doesn't have fitting include block), it prints out an error message indicating which .h file needs to be added to the file. The conversion was done in the following steps. 1. The initial automatic conversion of all .c files updated slightly over 4000 files, deleting around 700 includes and adding ~480 gfp.h and ~3000 slab.h inclusions. The script emitted errors for ~400 files. 2. Each error was manually checked. Some didn't need the inclusion, some needed manual addition while adding it to implementation .h or embedding .c file was more appropriate for others. This step added inclusions to around 150 files. 3. The script was run again and the output was compared to the edits from #2 to make sure no file was left behind. 4. Several build tests were done and a couple of problems were fixed. e.g. lib/decompress_*.c used malloc/free() wrappers around slab APIs requiring slab.h to be added manually. 5. The script was run on all .h files but without automatically editing them as sprinkling gfp.h and slab.h inclusions around .h files could easily lead to inclusion dependency hell. Most gfp.h inclusion directives were ignored as stuff from gfp.h was usually wildly available and often used in preprocessor macros. Each slab.h inclusion directive was examined and added manually as necessary. 6. percpu.h was updated not to include slab.h. 7. Build test were done on the following configurations and failures were fixed. CONFIG_GCOV_KERNEL was turned off for all tests (as my distributed build env didn't work with gcov compiles) and a few more options had to be turned off depending on archs to make things build (like ipr on powerpc/64 which failed due to missing writeq). * x86 and x86_64 UP and SMP allmodconfig and a custom test config. * powerpc and powerpc64 SMP allmodconfig * sparc and sparc64 SMP allmodconfig * ia64 SMP allmodconfig * s390 SMP allmodconfig * alpha SMP allmodconfig * um on x86_64 SMP allmodconfig 8. percpu.h modifications were reverted so that it could be applied as a separate patch and serve as bisection point. Given the fact that I had only a couple of failures from tests on step 6, I'm fairly confident about the coverage of this conversion patch. If there is a breakage, it's likely to be something in one of the arch headers which should be easily discoverable easily on most builds of the specific arch.

* media: move omap24xxcam's probe function to .devinit.textUwe Kleine-König2010-03-071-1/+1
| | | | | | | | | | | | | | | | | | | | | A pointer to omap24xxcam_probe is passed to the core via platform_driver_register and so the function must not disappear when the .init sections are discarded. Otherwise (if also having HOTPLUG=y) unbinding and binding a device to the driver via sysfs will result in an oops as does a device being registered late. An alternative to this patch is using platform_driver_probe instead of platform_driver_register plus removing the pointer to the probe function from the struct platform_driver.

| | | | | | | | | | | | | | | | The video_device::minor field is used where it shouldn't, either to - test for error conditions that can't happen anymore with the current v4l-dvb core, - store the value in a driver private field that isn't used anymore, - check the video device type where video_device::vfl_type should be used, or - create the name of a kernel thread that should get a stable name.

| | | | | | | | | | | | The v4l2-ioctl core now only allows buffer types for which the corresponding ->vidioc_try_fmt_xxx() methods are defined to be used in vidioc_(g|s)_parm. This driver only defines ->vidioc_try_fmt_vid_cap() so only VIDEO_CAPTURE buffers are allowed to be used with vidioc_s_parm() and vidioc_g_parm().

* V4L/DVB (10960): omap24xxcam: don't set vfl_type.Hans Verkuil2009-03-301-1/+0
| | | | | | | | | | | | | | | The vfl_type field is set by the core, so anything you fill in here will be overwritten. And it will be set to a VFL_TYPE_ value, not a VID_TYPE_ value which is an obsolete V4L1 type. Since these V4L1 types have been made unavailable for V4L2 drivers, this driver stopped compiling. In this case the fix is just removing this assignment.
