2009-03-30V4L/DVB (11141): em28xx: fix oops on ARM platform when allocating transfer ↵Devin Heitmueller
buffers Add missing URB_NO_TRANSFER_DMA_MAP flag, since the use of consistent memory is not permitted for DMA on the ARM platform. Thanks to Paul Thomas <pthomas8589@gmail.com> for providing sample ARM hardware that was experiencing the oops (tested on the at91rm9200 based LinuxStamp).

2009-03-30V4L/DVB (10519): em28xx: Fix for em28xx audio startupRobert Krakora
Essentially if a snd_em28xx_capture_trigger() stop followed by a snd_em28xx_capture_trigger() start would not yield any data because there was some logic put in with an adev->shutdown variable which did not seem warranted in my humble opinion. It would cause snd_em28xx_capture_trigger start never to start up the audio stream until the device was closed and reopened again. Upon re-opening the device adev->shutdown is reset and audio data would again flow.

2009-02-27V4L/DVB (10659): em28xx: register device to soundcard for sysfsNicola Soranzo
As explained in "Writing an ALSA driver" (T. Iwai), audio drivers should set the struct device for the card before registering the card instance. This will add the correct /sys/class/sound/cardN/device symlink, so HAL can see the device and ConsoleKit sets its ACL permissions for the logged-in user. For em28xx audio capture cards found e.g. in Hauppauge WinTV-HVR-900 (R2), this patch fixes errors like: ALSA lib pcm_hw.c:1429:(_snd_pcm_hw_open) Invalid value for card Error opening audio: Permission denied when running mplayer as a normal user.

Since pre-emption is enabled then it is safe to de-allocate the memory if you first unlink each URB. In this instance you are safe since pre-emption is disabled.

2008-12-30V4L/DVB (10130): use USB API functions rather than constantsJulia Lawall
This set of patches introduces calls to the following set of functions: usb_endpoint_dir_in(epd) usb_endpoint_dir_out(epd) usb_endpoint_is_bulk_in(epd) usb_endpoint_is_bulk_out(epd) usb_endpoint_is_int_in(epd) usb_endpoint_is_int_out(epd) usb_endpoint_is_isoc_in(epd) usb_endpoint_is_isoc_out(epd) usb_endpoint_num(epd) usb_endpoint_type(epd) usb_endpoint_xfer_bulk(epd) usb_endpoint_xfer_control(epd) usb_endpoint_xfer_int(epd) usb_endpoint_xfer_isoc(epd) In some cases, introducing one of these functions is not possible, and it just replaces an explicit integer value by one of the following constants: USB_ENDPOINT_XFER_BULK USB_ENDPOINT_XFER_CONTROL USB_ENDPOINT_XFER_INT USB_ENDPOINT_XFER_ISOC An extract of the semantic patch that makes these changes is as follows: (http://www.emn.fr/x-info/coccinelle/) // <smpl> @r1@ struct usb_endpoint_descriptor *epd; @@ - ((epd->bmAttributes & \(USB_ENDPOINT_XFERTYPE_MASK\|3\)) == - \(USB_ENDPOINT_XFER_CONTROL\|0\)) + usb_endpoint_xfer_control(epd) @r5@ struct usb_endpoint_descriptor *epd; @@ - ((epd->bEndpointAddress & \(USB_ENDPOINT_DIR_MASK\|0x80\)) == - \(USB_DIR_IN\|0x80\)) + usb_endpoint_dir_in(epd) // </smpl> Signed-off-by: Julia Lawall <julia@diku.dk> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
2008-12-30V4L/DVB (10125): em28xx: Don't do AC97 vendor detection for i2s audio devicesDevin Heitmueller
The current code was trying to query the AC97 registers for the vendor information even if it was clearly not a AC97 audio device (resulting in errors in the dmesg output). This was due to a bug in the way we did the check. Signed-off-by: Devin Heitmueller <dheitmueller@linuxtv.org> Signed-off-by: Mauro Carvalho Chehab <mchehab@redhat.com>
