Randy Dunlap <randy.dunlap@oracle.com> reported a breakage while compiling drivers/staging/tm6000, due to this change: commit 1c1b78bee1a94f98deeb9c24b21c4812e191646c Author: Greg Kroah-Hartman <gregkh@suse.de> Date: Thu Apr 29 15:46:07 2010 -0700 USB: remove unused usb_buffer_alloc and usb_buffer_free macros Now that all callers are converted over, remove the compatibility functions and all is good. As the function got renamed, the rename should also be applied at tm6000. Acked-by:Randy Dunlap <randy.dunlap@oracle.com> Signed-off-by:

The values for the fourcc format were correct, but applied to the wrong register. With this change, video is now barely working again with tm6000. While here, let's remove, for now, the memset. This way, people can have some image when testing this device. Yet to be fixed: parts of the image frame are missed. As we don't clean the buffers anymore, this is "recovered" by repeating the values from a previous frame. The quality is bad, since the image pixels will contain data from some previous frames, generating weird delay artifacts. Signed-off-by: -

Changing a video standard takes a long time to happen on tm6000, since it needs to load another firmware, and the i2c implementation on this device is really slow. When the driver tries to change the video standard, a kernel panic is produced: BUG: unable to handle kernel NULL pointer dereference at 0000000000000008 IP: [<ffffffffa0c7b48a>] tm6000_irq_callback+0x57f/0xac2 [tm6000] ... Kernel panic - not syncing: Fatal exception in interrupt By inspecting it with gdb: (gdb) list *tm6000_irq_callback+0x57f 0x348a is in tm6000_irq_callback (drivers/staging/tm6000/tm6000-video.c:202). 197 /* FIXME: move to tm6000-isoc */ 198 static int last_line = -2, start_line = -2, last_field = -2; 199 200 /* FIXME: this is the hardcoded window size 201 */ 202 unsigned int linewidth = (*buf)->vb.width << 1; 203 204 if (!dev->isoc_ctl.cmd) { 205 c = (header >> 24) & 0xff; 206 Clearly, it was the trial to access *buf, at line 202 that caused the Panic. As ioctl is serialized, While S_STD is handled,QBUF/DQBUF won't be called. So, the driver will run out of the buffers, and *buf will become NULL. As, on tm6000, the same URB can contain more than one video buffer, it is likely to hit a condition where no new buffer is available whily copying the streams. The fix is to leave the URB copy loop, if there's no more buffers are available. The same bug could also be produced by an application that is not fast enough to request new video buffers. The same bug were reported by Bee Hock Goh <beehock@gmail.com>. Thanks-to: Bee Hock Goh <beehock@gmail.com> for reporting the bug Signed-off-by: -

Although the code is getting the better alternates, it is not really using it. Get the interface/alternate numbers and use it where needed. This patch implements also one small fix at the last_line set, as proposed by Bee Hock Goh <behock@gmail.com>. Signed-off-by: -

According to the V4L2 specification, applications set bytesused, field and timestamp fields of struct v4l2_buffer when the buffer is intended for output and memory type is MMAP. This adds proper copying of those values to videobuf_buffer so drivers can use them. Signed-off-by:

This is a virtual device driver for testing the memory-to-memory framework. This virtual device uses in-memory buffers for both its source and destination. It is capable of multi-instance, multi-buffer-per-transaction operation (via the mem2mem framework).

A mem-to-mem device is a device that uses memory buffers passed by userspace applications for both their source and destination data. This is different from existing drivers, which utilize memory buffers for either input or output, but not both. In terms of V4L2 such a device would be both of OUTPUT and CAPTURE type. Examples of such devices would be: image 'resizers', 'rotators', 'colorspace converters', etc. This patch adds a separate Kconfig sub-menu for mem-to-mem devices as well. Signed-off-by:
