Hello all, I've been running Voyage 0.10.0 for a while but unfortunately it doesn't run very smooth compared to 0.7.5. It's running on a Soekris net5501. With normal 44.1 files its running fine but with higher resolutions it stutters/distorts every few seconds or so, quite annoying.
I've loaded 0.7.5 on the CF card of the 5501 and the main differences are in the load IRQ processes are creating. 5501: The following processes are producing a combined 15-20% cpu load depending on the resolution currently being played. In 0.7.5. these processes are not visible, so I'm not sure what that means. irq/15-ehci_hcd irq/15-ohci_ irq/15-pata_amd_hcd However: - ksoftirq is also slightly elevated at 1.6 when running 0.10.0 compared to 0 on the 0.7.5. - The si line in 'top' seems also to be quite high (between 2 and 7) compared to when running 0.7.5 (between 0 and and occasional 0.3). - system load is also quite high It seems to me I have an irq problem, and the output of cat /proc/interrupts (see below) seems to give some confirmation. The pata and the usb irq's are shared in 0.10.0. This makes sense since the music files are locally stored and accessed through a pata interface. Anyone any ideas on how to fix this? Does anyone know what has changed between 0.7.5 and 0.10 that might have caused this change? Kind regards and thanks in advance, Maarten 0.7.5: cat /proc/interrupts CPU0 0: 2610959 XT-PIC-XT-PIC timer 1: 0 XT-PIC-XT-PIC i8042 2: 0 XT-PIC-XT-PIC cascade 3: 1 XT-PIC-XT-PIC 4: 273 XT-PIC-XT-PIC serial 7: 1 XT-PIC-XT-PIC 11: 41747 XT-PIC-XT-PIC eth0 14: 188673 XT-PIC-XT-PIC ide0 15: 3926610 XT-PIC-XT-PIC ehci_hcd:usb1, ohci_hcd:usb2 NMI: 0 Non-maskable interrupts LOC: 0 Local timer interrupts SPU: 0 Spurious interrupts PMI: 0 Performance monitoring interrupts IWI: 0 IRQ work interrupts RES: 0 Rescheduling interrupts CAL: 0 Function call interrupts TLB: 0 TLB shootdowns ERR: 1 MIS: 0 0.10.0: cat /proc/interrupts CPU0 0: 302642 XT-PIC-XT-PIC timer 1: 0 XT-PIC-XT-PIC i8042 2: 0 XT-PIC-XT-PIC cascade 4: 515 XT-PIC-XT-PIC serial 8: 1 XT-PIC-XT-PIC rtc0 11: 2473 XT-PIC-XT-PIC eth0 14: 11585 XT-PIC-XT-PIC pata_amd 15: 38 XT-PIC-XT-PIC pata_amd, ehci_hcd:usb1, ohci_hcd:usb2 NMI: 0 Non-maskable interrupts LOC: 0 Local timer interrupts SPU: 0 Spurious interrupts PMI: 0 Performance monitoring interrupts IWI: 0 IRQ work interrupts RTR: 0 APIC ICR read retries RES: 0 Rescheduling interrupts CAL: 0 Function call interrupts TLB: 0 TLB shootdowns ERR: 0 MIS: 0 _______________________________________________ Voyage-linux mailing list Voyage-linux@list.voyage.hk http://list.voyage.hk/mailman/listinfo/voyage-linux
