* V4L/DVB: pvrusb2: Enforce a 300msec stabilization interval during stream strartMike Isely2010-02-261-0/+1
| | | | | | | | | | | | Martin Dauskardt <martin.dauskardt@gmx.de> has determined that the encoder has a much better chance of starting cleanly if we deliberately hold off starting it util the video digitizer has had a chance to run for at least 300msec first. These changes implement an enforced 300msec wait in the state machine that orchestrates streaming start / stop.

* V4L/DVB (10239): pvrusb2: Fix misleading comment caused by earlier commitMike Isely2009-03-301-2/+1
| | | | | | | | | | | | | | | | Previous v4l-dvb changeset id 4cc8ed11e2e0 changed the pvrusb2-hdw internal API regarding i2c chip debug register access. However that change failed to also update the corresponding function comment describing the API. As driver maintained I never saw a request for an ack on that change; there probably should have been one especially since the manner in which this API operates was changed - its interface is now entangled with a v4l specific struct and I would have preferred to keep this API clear of moving-target v4l-isms such as this one if at all possible which is why I had done it the way I did before. But whatever. This commit at least fixes the comment issue. Signed-off-by: Mike Isely <isely@pobox.com> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>

| | | | | | | | | | Implement a new internal function to create a string device identifier. This ID stays with the specific device, making it useful to user space to identify specific devices.

* V4L/DVB (10141): v4l2: debugging API changed to match against driver name ↵Hans Verkuil2009-01-021-2/+2
| | | | | | | | | | | | | | | | instead of ID. Since the i2c driver ID will be removed in the near future we have to modify the v4l2 debugging API to use the driver name instead of driver ID. Note that this API is not used in applications other than v4l2-dbg.cpp as it is for debugging and testing only. Should anyone use the old VIDIOC_G_CHIP_IDENT, then this will be logged with a warning that it is deprecated and will be removed in 2.6.30.

* V4L/DVB (8900): pvrusb2: Implement cropping pass throughMike Isely2008-10-121-0/+9
| | | | | | | | | | | | | This builds upon the previous pvrusb2 change to more formally implement full cropping support. This enables access from the driver's V4L interface, and enables access to full capabilities from sysfs as well. Note that this is only effective when in analog mode. It also will only work when the underlying digitizer's driver (saa7115 or cx25840 depending on the hardware) also implements the appropriate functions.

* V4L/DVB (7321): pvrusb2: Rework context handling and initializationMike Isely2008-04-241-3/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This change significantly rearranges pvr2_context level initialization and operation: 1. A new kernel thread is set up for management of the context. 2. Destruction of the pvr2_context instance is moved into the kernel thread. No other context is able to remove the instance; doing this simplifies lock handling. 3. The callback into pvrusb2-main, which is used to trigger initialization of each interface, is now issued from this kernel thread. Previously it had been indirectly issued out of the work queue thread in pvr2_hdw, which led to deadlock issues if the interface needed to change a control setting (which in turn requires dispatch of another work queue entry). 4. Callbacks into the interfaces (via the pvr2_channel structure) are now issued strictly from this thread. The net result of this is that such callback functions can now also safely operate driver controls without deadlocking the work queue. (At the moment this is not actually a problem, but I'm anticipating issues with this in the future). 5. There is no longer any need for anyone to enter / exit the pvr2_context structure. Implementation of the kernel thread here allows this all to be internal now, simplifying other logic. 6. A very very longstanding issue involving a mutex deadlock between the pvrusb2 driver and v4l should now be solved. The deadlock involved the pvr2_context mutex and a globals-protecting mutex in v4l. During initialization the driver would take the pvr2_context mutex first then the v4l2 interface would register with v4l and implicitly take the v4l mutex. Later when v4l would call back into the driver, the two mutexes could possibly be taken in the opposite order, a situation that can lead to deadlock. In practice this really wasn't an issue unless a v4l app tried to start VERY early after the driver appeared. However it still needed to be solved, and with the use of the kernel thread relieving need for pvr2_context mutex, the problem should be finally solved.

* V4L/DVB (7319): pvrusb2: Close potential race condition during initializationMike Isely2008-04-241-5/+6

| | | | | | | | | | The pvrusb2 driver has used hardcoded logic to control the LED on the device. However this is really Hauppauge-specific behavior.

| | | | | | | | | | Previously the pvrusb2 driver just started with the default input to be "television". But if the device doesn't support an analog tuner then this default must be different.

* V4L/DVB (7297): pvrusb2: Dynamically control range of input selectionsMike Isely2008-04-241-3/+4

| | | | | | | | | | | | | | | | place The pvrusb2 driver currently supports two variants of the Hauppauge PVR USB2. However there are other hardware types potentially supportable, but the driver at the moment is not structured to make it easy to describe these minor variations. This changeset is the first set of changes to make such additional device support possible. Device attributes are held in several tables all contained within pvrusb2-devattr.c; all other device-specific driver behavior now derives from these tables.

* V4L/DVB (6691): pvrusb2: Rework pipeline state controlMike Isely2008-01-251-65/+70
| | | | | | | | | | | | | | | | | | | | | This is a new implementation for video pipeline control within the pvrusb2 driver. Actual start/stop of the pipeline is moved to the driver's kernel thread. Pipeline stages are controlled autonomously based on surrounding pipeline or application control state. Kernel thread management is also cleaned up and moved into the internal control structure of the driver, solving a set up / tear down race along the way. Better failure recovery is implemented with this new control strategy. Also with this change comes better control of the cx23416 encoder, building on additional information learned about the peculiarities of controlling this part (this information was the original trigger for this rework). With this change, overall encoder stability should be considerably improved. Yes, this is a large change for this driver, but due to the nature of the feature being worked on, the changes are fairly pervasive and would be difficult to break into smaller pieces with any semblence of step-wise stability.

| | | | | | | | | | | | | The pvrusb2 driver already has a method for extracting the FX2's program memory back out to a user application; this ability is used to facilitate manual firmware extraction as per the procedure documented on the pvrusb2 web site. This change follows that pattern and implements a corresponding method to grab the binary contents of the PVR USB2 prom (which for PVR USB2 devices can contain information in addition to the usual Hauppauge metadata).

* V4L/DVB (5507): Pvrusb2: Gather USB bus address info and report itMike Isely2007-04-271-0/+3
| | | | | | | | | | The V4L2 API requires a unique bus_info string returned as part of the v4l2_capability structure.

| | | | | | | | | | | Support 64 bit register IDs internally. Only allow root access to this API (for both set and get). Note that actual 64 bit access only becomes possible once the definition for v4l2_register is updated, but this change clears the way for it from the viewpoint of the pvrusb2 driver.

* V4L/DVB (5146): Make VIDIOC_INT_[SG]_REGISTER ioctls no longer internal onlyTrent Piepho2007-02-211-1/+1
| | | | | | | | | | | | | | | | | | | | | The direct register access ioctls were defined as kernel internal only, but they are very useful for debugging hardware from userspace and are used as such. Officially export them. VIDIOC_INT_[SG]_REGISTER is renamed to VIDIOC_DBG_[SG]_REGISTER Definition of ioctl and struct v4l2_register is moved from v4l2-common.h to videodev2.h. Types used in struct v4l2_register are changed to the userspace exportable versions (u32 -> __u32, etc). Use of VIDIOC_DBG_S_REGISTER requires CAP_SYS_ADMIN permission, so move the check into the video_ioctl2() dispatcher so it doesn't need to be duplicated in each driver's call-back function. CAP_SYS_ADMIN check is added to pvrusb2 (which doesn't use video_ioctl2). Signed-off-by: Trent Piepho <xyzzy@speakeasy.org> Signed-off-by: Mauro Carvalho Chehab <mchehab@infradead.org>
