* V4L/DVB (3516): Make video_buf more genericMauro Carvalho Chehab2006-03-24
| | | | | | | | | | | Video_buf were concerned to allow PCI devices to be used as video capture devices. This patch extends video_buf features by virtualizing pci-dependent functions and allowing other type of devices to use it. It is still DMA centric, although it may be used also by devices that emulates scatter/gather behavior or a DMA device Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>

* V4L/DVB (3420): Nskips maybe used uninitialized in bttv_risc_overlayDuncan Sands2006-03-21
| | | | | | | | The Coverity checker (previously Stanford checker) noticed that the value of nskips could be read even if it was never written. Signed-off-by: Duncan Sands <baldrick@free.fr> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
* V4L/DVB (3394): Bttv: correct bttv_risc_packed buffer sizeDuncan Sands2006-02-26
| | | | | | | | | | | | | | | | | | | | | | | | This patch fixes the strange crashes I was seeing after using bttv card, caused by a buffer overflow in bttv_risc_packed. The instruction buffer size calculation contains two errors: (a) a non-zero padding value can push the start of the next bpl section to just before a page border, leading to more scanline splits and thus additional instructions. (b) the first DMA region can be smaller than one page, so there can be a scanline split even if bpl*lines is smaller than PAGE_SIZE. For example, consider the case where offset is 0, bpl is 2, padding is 4094, lines is smaller than 2048, the first DMA region has size 1 and all others have size PAGE_SIZE, assumed to equal 4096. Then all bpl regions cross page borders and the number of instructions written is 2*lines+2, rather than lines+2 (the current estimate). With this patch the number of instructions for this example is estimated to be 2*lines+3. Also, the BUG_ON that was supposed to catch buffer overflows contained a thinko causing it fire only if the buffer was overrun by a factor of 16 or more, so it fixes the the BUG_ON's (using sizeof rather than "4").

Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
