| Summary | 0000281: MIDI memory pool error under Linux kernel 2.4.x | ||||
| Description | This is an issue I have been encountering when running latencies (with or without automation) at or below 3 ms latency (i.e., p=256, n=2 @ 48KHz sampling rate) when running a 2.4 kernel. In this case, the ardour log window displays a bizarre error message saying something about a MIDI memory pool error and to please compile with larger size. When I run a 2.6 kernel, this error does not seem to occur. FYI, this is on a gentoo linux installation, tested with the following kernel versions and settings: ck-sources-2.4.23-r1 wirh lowlatency and preempt enabled gentoo-dev-sources-2.6.3-r1 with elevator=as and preempt enabled | ||||
| Additional Information | My system is an Abit BX6-R2 with a Pentuum III 450 (Katmai), 768 MB RAM, Hammerfall DSP 9652, using reiserfs as the filestore for my audio files, and jack-audio-connection-kit-0.94.0 compiled /dev/shm on tmpfs. Most sessions I am running 8 tracks or less, and more typically just 5 - 7 tracks. Please note that I have optimized my IRQs and hdparm settings based on the FAQs I read for linux audio, and to reduce the possibility PCI bus contention I am running an AGP card with an open source XFree86 driver that does not increase the latency of the AGP card. | ||||
