2010-05-19V4L/DVB: V4L2: Replace loops for finding max buffers in VIDIOC_REQBUFS callbacksAndreas Bombe
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>

2010-03-30include cleanup: Update gfp.h and slab.h includes to prepare for breaking ↵Tejun Heo
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.

ir_input_register() We'll need to register a sysfs class for the IR devices. As such, the better is to have the input_register_device()/input_unregister_device() inside the ir register/unregister functions.

2009-12-05V4L/DVB (13238): v4l2_subdev: rename tuner s_standby operation to core s_powerLaurent Pinchart
Upcoming I2C v4l2_subdev drivers need a way to control the subdevice power state from the core. This use case is already partially covered by the tuner s_standby operation, but no way to explicitly come back from the standby state is available. Rename the tuner s_standby operation to core s_power, and fix tuner drivers accordingly. The tuner core will call s_power(0) instead of s_standby(). No explicit call to s_power(1) is required for tuners as they are supposed to wake up from standby automatically.

Instead notes in the comments describe what needs to be done for IR Tx to work in the subdevice implementation. The current Tx behavior is skeletal and benign. If left alone, it does nothing. It will only ever generate a Tx interrupt on Tx init by a caller or when the tx_write() method is called. The ISR, when called, will then disable the Tx FIFO service interrupt.

integrated IR controller This change adds a skeletal implementation of a v4l2_subdevice to provide encapsulation and abstraction of the CX23888's integrated consumer infrared controller. This change also instantiates the cx23888_ir subdev for the HVR-1850 which has IR hardware physically wired up to a CX23888. The cx23888_ir subdev code is being written with long-term objectives to: 1. port it to the cx25840 module for the CX2584x, CX2583x, CX23885, & CX231xx IR controllers 2. possibly port it to the cx18 module for the CX23418 IR controller 3. have the IR subdevice accessed abstractly in the cx23885 module, so the driver can ignore the difference between the CX23885 and CX23888.

Now v4l2-dbg can be used to manipulate CX2388[578] and CX23417 registers including the CX2388[57] functions handled by the cx25840 module.
