2012-03-19[media] partially reverts changeset fa5527cMauro Carvalho Chehab1-52/+0
This patch is applying some hunks that are already at changeset c247d7b, causing a compilation breakage. Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2012-03-19[media] em28xx: support for 2304:0242 PCTV QuatroStick (510e)Ivan Kalvachev3-1/+82
It is mostly copy/paste of the 520e code with setting GPIO7 removed (no LED light). I've worked on just released vanilla linux-3.3.0 kernel, so there may be 1/2 lines offset to the internal working source, but most of the code should apply cleanly. I was able to get the DVB-C working (tuned and watched TV). Haven't tested DVB-T (no signal atm). Special thanks to everybody who worked on the code and to Antti Palosaari and Devin Heitmueller who provided essential support on irc.

2012-03-08[media] em28xx: pre-allocate DVB isoc transfer buffersGianluca Gennari5-66/+142
On MIPS/ARM set-top-boxes, as well as old x86 PCs, memory allocation failures in the em28xx driver are common, due to memory fragmentation over time, that makes impossible to allocate large chunks of coherent memory. A typical system with 256/512 MB of RAM fails after just 1 day of uptime (see the old thread for detailed reports and crashlogs). In fact, the em28xx driver allocates memory for USB isoc transfers at runtime, as opposite to the dvb-usb drivers that allocates the USB buffers when the device is initialized, and frees them when the device is disconnected. Moreover, in digital mode the USB isoc transfer buffers are freed, allocated and cleared every time the user selects a new channel, wasting time and resources. This patch solves both problems by allocating DVB isoc transfer buffers in em28xx_usb_probe(), and freeing them in em28xx_usb_disconnect(). In fact, the buffers size and number depend only on the max USB packet size that is parsed from the USB descriptors in em28xx_usb_probe(), so it can never change for a given device. This approach makes no sense in analog mode (as the buffer size depends on the alternate mode selected at runtime), the patch creates two separate sets of buffers for digital and analog modes. For digital-only devices, USB buffers are created when the device is probed and freed when the device is disconnected. For analog-only devices, nothing changes: isoc buffers are created at runtime. For hybrid devices, two sets of buffers are maintained: the digital-mode buffers are created when the device is probed, and freed when the device is disconnected; analog-mode buffers are created/destroyed at runtime as before. So, in analog mode, digital and analog buffers coexists at the same time: this can be justified by the fact that digital mode is by far more commonly used nowadays, so it makes sense to optimize the driver for this use case scenario. The patch has been tested in the last few days on a x86 PC and a MIPS set-top-box, with the PCTV 290e (digital only) and the Terratec Hybrid XS (hybrid device). With the latter, I switched several times between analog and digital mode (Kaffeine/TvTime) with no issue at all. I unplugged/plugged the devices several times with no problem. Also, after over 3 days of normal usage in the MPIS set-top-box, the PCTV 290e was still up and running.

The MaxPacketSize for em2800 based devices is too small to capture at full resolution. Therefore scale down when the maximum frame size is selected. The previous workaround that simply reduced the X resolution cannot be used because it crops a part of the input as the em2800 can only scale down with a factor of 0.5. reverts commits 1ca31892e and fb3de0398ab.

2011-09-25[media] em28xx: replug locking cleanupChris Rankin1-4/+7
Simplifies the locking by moving the em28xx_init_extension() call until em28xx_usb_probe() has finished with the dev->lock mutex. It therefore makes the second and subsequent "plugging" events logically identical to the first "plugging" event when the em28xx-dvb and em28xx-alsa modules must be loaded (i.e. registered). Basically, em28xx_usb_probe() requests that em28xx-dvb be loaded and also triggers udev to initialise the V4L2 devices. These two events are serialised by the dev->lock mutex but the order that they happen in is undefined. But this has always been the case anyway.

This fixes the deadlock that occurs with either multiple PCTV 290e adapters or when a single PCTV 290e adapter is replugged. For DVB devices, the device lock must now *not* be held when adding/removing either a device or an extension to the respective lists. (Because em28xx_init_dvb() will want to take the lock instead). Conversely, for Audio-Only devices, the device lock *must* be held when adding/removing either a device or an extension to the respective lists.

2011-09-24[media] em28xx: fix race on disconnectChris Rankin2-23/+8
This patch closes the race on the device and extension lists at USB disconnect time. Previously, the device was removed from the device list during em28xx_release_resources(), and then passed to the em28xx_close_extension() function so that all extensions could run their fini() operations. However, this left a (brief, theoretical, highly unlikely ;-)) window between these two calls during which a new module could call em28xx_register_extension(). The result would have been that the em28xx_usb_disconnect() function would also have passed the device to the new extension's fini() function, despite never having called the extension's init() function. This patch also restores em28xx_close_extension()'s symmetry with em28xx_init_extension(), and establishes the property that every device in the device list must have been initialised for every extension in the extension list.

2011-09-03[media] em28xx: don't sleep on disconnectChris Rankin1-2/+20
The DVB framework will try to power-down an adapter that no-one is using any more, but this assumes that the adapter is still connected to the machine. That's not always true for a USB adapter, so disable the sleep operations when the adapter has been physically unplugged. This prevents I2C write failures with error -19 from appearing occasionally in the dmesg log.

2011-09-03[media] em28xx: clean up resources should init failChris Rankin2-45/+37
This patch ensures that the em28xx_init_dev() function cleans up after itself, in the event that it fails. This isimportant because the struct em28xx will be deallocated if em28xx_init_dev() returns an error.
