Hi, I want to try what Lee mentioned a couple of times recently: Low latency audio performance with 2.6 mainline -- no mingo-patch, no rt-lsm (athlon xp 2600+, asus a7v8x-x, hdsp. On a 2.4.26 with lck patches this system has good lowlat performance, solid jackd with -p 64 -n 2, so the hardware should be ok. Ah well, looong dropouts on deep reiserfs walks that never show up in jackd's messages but that's hopefully another story). Got 2.6.16.16 from kernel.org. If I understood Lee right I could expect a jackd with -p 64 -n 2 to work just fine but it doesn't. Loads of xruns. What am I missing? What can I do to find out? With make oldconfig I come across some questions I'm unsure about. Are these answers right? Thanks in advance. # IO Schedulers # CONFIG_IOSCHED_NOOP=y CONFIG_IOSCHED_AS=y CONFIG_IOSCHED_DEADLINE=y CONFIG_IOSCHED_CFQ=y CONFIG_DEFAULT_AS=y # CONFIG_DEFAULT_DEADLINE is not set # CONFIG_DEFAULT_CFQ is not set # CONFIG_DEFAULT_NOOP is not set CONFIG_DEFAULT_IOSCHED="anticipatory" --- # Processor type and features # # CONFIG_HPET_TIMER is not set # CONFIG_SMP is not set # CONFIG_PREEMPT_NONE is not set # CONFIG_PREEMPT_VOLUNTARY is not set CONFIG_PREEMPT=y CONFIG_PREEMPT_BKL=y --- # Firmware Drivers # # CONFIG_HZ_100 is not set # CONFIG_HZ_250 is not set CONFIG_HZ_1000=y CONFIG_HZ=1000 --- CONFIG_SND_RTCTIMER=m CONFIG_SND_SEQ_RTCTIMER_DEFAULT=y -- Wolfgang
