* [media] em28xx: support for 2304:0242 PCTV QuatroStick (510e)Ivan Kalvachev2012-03-191-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | 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.

* [media] em28xx: pre-allocate DVB isoc transfer buffersGianluca Gennari2012-03-081-4/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* [media] em28xx: increase maxwidth for em2800Sascha Sommer2012-01-101-1/+1
| | | | | | | | | | | | | | 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.

Note that this version just drops the actual VBI data onto the floor as opposed to processing it. The "#ifdef 0" tags are for the videobuf code that appears in the next patch in this series. We created a separate version of the isoc_copy version for parsing the version of the stream that includes VBI data. In theory, they might be able to be merged at some point in the future, but the initial goal is to ensure that we do not cause any regressions with devices that do not have VBI support.
