* [media] cx231xx: don't DMA to random addressesDavid Dillow2012-07-061-1/+1
| | | | | | | | | | | | | | | Commit 7a6f6c29d264cdd2fe0eb3d923217eed5f0ad134 (cx231xx: use URB_NO_TRANSFER_DMA_MAP) was intended to avoid mapping the DMA buffer for URB twice. This works for the URBs allocated with usb_alloc_urb(), as those are allocated from cohernent DMA pools, but the flag was also added for the VBI and audio URBs, which have a manually allocated area. This leaves the random trash in the structure after allocation as the DMA address, corrupting memory and preventing VBI and audio from working. Letting the USB core map the buffers solves the problem.

* [media] cx231xx: use URB_NO_TRANSFER_DMA_MAP on URBs allocated with ↵Thomas Petazzoni2012-01-101-1/+1
| | | | | | | | | | | | | | | | | | | | | | usb_alloc_urb() URBs allocated with usb_alloc_urb() are allocated from DMA-coherent areas, and therefore it is not necessary to call dma_map_single() on such buffers. Worst, on ARM, calling dma_map_single() on a DMA-coherent buffer will trigger a BUG_ON() in arch/arm/mm/dma-mapping.c. Therefore, we mark all URBs allocated with usb_alloc_urb() with the URB_NO_TRANSFER_DMA_MAP transfer_flags, so that the USB core does not do dma_map_single()/dma_unmap_single() on those buffers. This is similar to 882787ff8fdeb0be790547ee9b22b281095e95da for the gspca driver, and has already been discussed on the linux-media list in the past: http://www.mail-archive.com/linux-media@vger.kernel.org/msg37086.html.

* [media] cx231xx: fix device disconnect checksMauro Carvalho Chehab2012-01-101-1/+1
| | | | | | | | | | | | | | | | The driver were using DEV_MISCONFIGURED on some places, and DEV_DISCONNECTED on others. In a matter of fact, DEV_MISCONFIGURED were set only during the usb disconnect callback, with was confusing. Also, the alsa driver never checks if the device is present, before doing some dangerous things. Remove DEV_MISCONFIGURED, replacing it by DEV_DISCONNECTED. Also, fixes the other usecases for DEV_DISCONNECTED. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

* [media] cx231xx: Ensure VBI fields are sent in the correct orderDevin Heitmueller2010-10-211-5/+18
| | | | | | | | | | | | | | | | The current code was sending one videobuf per field (despite having specified V4L2_FIELD_SEQ_TB during setup). As a result, application which used the read() interface would work, except they would sometimes have the fields reversed (depending on the luck of which field the device was on when the application started VBI capture). The net effect was that CC decoding would only work about 50% of the time. Restructure the VBI code a bit so that works like all the other drivers, such that both fields are delivered in a single videobuf buffer, which ensures that they are always received in a predictable order.

* 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.
