Fwd: BUG: 2.6.22-rc4 Ubuntu 7.04 AUDIO ALSA

2007-06-09 Thread Dan Collins


[1.] One line summary of the problem: Audio card not detected under
kernel, card is SigmaTel, computer is a Dell XPS 400
[2.] Full description of the problem/report:
The volume control did not find any elements and/or devices to
control. This means either that you don't have the right GStreamer
plugins installed, or that you don't have a sound card configured.


You can remove the volume control from the panel by right-clicking the
speaker icon on the panel and selecting "Remove From Panel" from the
menu.

[PATCH] Fixed TPACKET V3 to signal poll when block is closed rather than for every packet

2014-12-18 Thread Dan Collins

Make TPACKET_V3 signal poll when block is closed rather than for every
packet. Side effect is that poll will be signaled when block retire
timer expires which didn't previously happen. Issue was visible when
sending packets at a very low frequency such that all blocks are retired
before packets are received by TPACKET_V3. This caused avoidable packet
loss. The fix ensures that the signal is sent when blocks are closed
which covers the normal path where the block is filled as well as the
path where the timer expires. The case where a block is filled without
moving to the next block (ie. all blocks are full) will still cause poll
to be signaled.
