The cx88 vb2 conversion and the vb2 dma_sg improvements were developed separately and were merged separately. Unfortunately, the patch updating drivers to the dma_sg improvements didn't take the updated cx88 driver into account. Basically two ships passing in the night, unaware of one another even though both ships have the same owner, i.e. me :-) Signed-off-by: NHans Verkuil <hans.verkuil@cisco.com> Reported-by: NChris Lee <updatelee@gmail.com> Signed-off-by: NMauro Carvalho Chehab <mchehab@osg.samsung.com>

The width, height and field values are core fields since both vbi, video and blackbird use the same video input. Move those fields to the correct struct. Also fix the field checks in the try_fmt functions: add V4L2_FIELD_SEQ_BT/TB support and map incorrect field values to a correct field value instead of returning an error.

The timeout is way too small. Especially complicated command like CX2341X_ENC_STOP_CAPTURE takes much more time than 10 ms. Increase the timeout to 1 second, just as ivtv does (the cx88-blackbird has the same IP core for MPEG compression as ivtv). This solves a nasty issue where STOP_CAPTURE would timeout and the mailbox is left in a busy state, making it impossible to start streaming a second time without reloading the driver first.

As usual, this patch is very large due to the fact that half a vb2 conversion isn't possible. And since this affects blackbird, alsa, core, dvb, vbi and video the changes are all over. What made this more difficult was the peculiar way the risc program was setup. The driver allowed for running out of buffers in which case the DMA would stop and restart when the next buffer was queued. There was also a complicated timeout system for when buffers weren't filled. This was replaced by a much simpler scheme where there is always one buffer around and the DMA will just cycle that buffer until a new buffer is queued. In that case the previous buffer will be chained to the new buffer. An interrupt is generated at the start of the new buffer telling the driver that the previous buffer can be passed on to userspace. Much simpler and more robust. Signed-off-by: NHans Verkuil <hans.verkuil@cisco.com> Signed-off-by: NMauro Carvalho Chehab <mchehab@osg.samsung.com>

All the modified drivers didn't have any version increment since Jan, 1 2011. Several of them didn't have any version increment for a long time, even having new features and important bug fixes happening. As we're now filling the QUERYCAP version with the current Kernel Release, we don't need to maintain a per-driver version control anymore. So, let's just use the default. In order to preserve the Kernel module version history, a KERNEL_VERSION() macro were added to all modified drivers, and the extraver number were incremented. I opted to preserve the per-driver version control to a few pwc, pvrusb2, s2255, s5p-fimc and sh_vou. A few drivers are still using the legacy way to handle ioctl's. So, we can't do such change on them, otherwise, they'll break. Those are: uvc, et61x251 and sn9c102. The rationale is that the per-driver version control seems to be actively maintained on those. Yet, I think that the better for them would be to just use the default version numbering, instead of doing that by themselves.

It should not be possible to enter mpeg_open and acquire core->lock without the blackbird driver being registered, so just error out if it is not. This makes the code more readable and should prevent the bug fixed by the patch "hold device lock during sub-driver initialization" from resurfacing again. Similarly, if we enter mpeg_release and acquire core->lock then either the blackbird driver is registered (since open files keep it loaded) or the sysadmin forced the driver's removal. In the latter case the state will be inconsistent and this is worth a loud warning.

cx8802_blackbird_probe makes a device node for the mpeg sub-device before it has been added to dev->drvlist. If the device is opened during that time, the open succeeds but request_acquire cannot be called, so the reference count remains zero. Later, when the device is closed, the reference count becomes negative --- uh oh. Close the race by holding core->lock during probe and not releasing until the device is in drvlist and initialization finished. Previously the BKL prevented this race.

The BKL conversion of this driver seems to have gone wrong. Loading the cx88-blackbird driver deadlocks. The cause: mpeg_ops::open in the cx2388x blackbird driver acquires the device lock and calls the sub-driver's request_acquire, which tries to acquire the lock again. Fix it by clarifying the semantics of request_acquire, request_release, advise_acquire, and advise_release: now all will rely on the caller to acquire the device lock.

The BKL conversion of this driver seems to have gone wrong. Various uses of the sub-device and driver lists appear to be subject to race conditions. In particular, some functions access drvlist without a relevant lock held, which will race against removal of drivers. Let's start with that --- clean up by consistently protecting dev->drvlist with dev->core->lock, noting driver functions that require the device lock to be held or not to be held. After this patch, there are still some races --- e.g., cx8802_blackbird_remove can run between the time the blackbird driver is acquired and the time it is used in mpeg_release, and there's a similar race in cx88_dvb_bus_ctrl. Later patches will address the remaining known races and the deadlock noticed by Andi. This patch just makes the semantics clearer in preparation for those later changes.

include cleanup: Update gfp.h and slab.h includes to prepare for breaking 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.
