Hi I am currently trying to port speex v1.1.6 to a microcontroller with very limited memory (<64Kbyte RAM). what I found when initialising the encoder, a chunk of 32Kb was attempted to be alloced, which failed: src/nb_celp.c: void *nb_encoder_init(const SpeexMode *m) { /* snip */ st = (EncState*)speex_alloc(sizeof(EncState)+8000*sizeof(spx_sig_t)); /* snip */ } same goes for the decod...

I have a PCI device which can perform bus master DMA. I developed a PCI device driver which can allocate DMA buffer and provide mmap operation to map the I/O and DMA buffer to user space. The PCI device driver works well under Linux 2.6.20. However it brokes under XEN 3.0.4. It appears that mmap map to the wrong memory. remap_pfn_range in mmap function return no error when it is used to map

Hi Iam using the script below to limit usage for the computers on my lan with respect to download and upload I have a 256kb up and 256 kb down connection, I want limit the speed of each computer to 64kbyte down and 32 up as a maximum. The script below works however it limits the up and down of the whole specified network to 64/32 ... what do I have to edit so that the script handles the requests on a per computer basis instead of a network as a whole. Thx for any suggestions #Download Section tc q...

...s possible to Unreal TV. My tests vary wildly. We have 3 servers: 1 Ogg Vorbis server, 1 MP3 server, and a 2nd MP3 server that's relaying (using a single-mount relay since the 1st MP3 server has fallbacks configured) from the 1st MP3 server. I am using Winamp 5 with stock streaming settings (64kbyte buffer with 45% prebuffer) to test, as that is what most listeners use. I am not using Icecast's burst-on-connect feature to try and keep buffers as manageable as possible. How I test is simple. I load up Foobar2000 with Oddcastv3, and stream music to the server. I then use Winamp to play t...

zdb -C shows an shift value on each vdev in my pool, I was just wondering if it is vdev specific, or pool wide. Google didn''t seem to know. I''m considering a mixed pool with some "advanced format" (4KB sector) drives, and some normal 512B sector drives, and was wondering if the ashift can be set per vdev, or only per pool. Theoretically, this would save me some size on

Hi, we are currently considering different options for rolling out a large scale IP PBX to handle around 3,000 + concurrent calls. Can this be done with Asterisk? Has it been done before? I really would like an input on this. Thanks! -------------- next part -------------- An HTML attachment was scrubbed... URL:
