[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [Xen-devel] Bug-reporting best practice? Xen/Gentoo -- Preparing to log interrupt info sometime after feb. 2016.
Hi all, I'm not a developer but I would like to set up my Xen system to get bug reports as useful as possible. At present I am logging the xen console via serial port, and I am running Xen compiled from gentoo ebuild with "debug" use flag. Is there anything more I need to set up to be able to collect as much useful info as possible? At present, this is my xen command line: xen_commandline : ssd-xen-debug-marker console_timestamps=date loglvl=all guest_loglvl=all sync_console iommu=1,verbose,debug iommu_inclusive_mapping=1 com1=115200,8n1 console=com1 dom0_max_vcpus=4 dom0_vcpus_pin=1 dom0_mem=8G,max:8G cpufreq=xen:performance,verbose tmem=1 sched_smt_power_savings=1 apic_verbosity=debug e820-verbose=1 core_parking=power (yes, I know, 8G for dom0, well, it is also acting as file server, I want to keep as much of the file-system in cache as I can ) Any changes I should make for maximally useful bug-reports? This is in preparation for the 4.7 release (april 2016 I gather) . I have some PCIe cards that are acting up, something to do with interrupts. I see some activity on that front right now, so I've decided to be an early adopter of 4.7, to be able to help as much as possible, maybe get any tweaks I might need for my system done in the source. I'm running gentoo, and have tried installing xen-*-9999 from the virtualization overlay, but it fails, seems it is trying to fetch the qemu sources twice, and failing. Is it me doing something wrong? Use flag "system-qemu" does not help. --------------- Additional info: The PCIe cards that are acting up are: 00:1b.0 Audio device: Intel Corporation C610/X99 series chipset HD Audio Controller (rev 05) 02:00.0 USB controller: ASMedia Technology Inc. ASM1042A USB 3.0 Host Controller 81:00.0 USB controller: ASMedia Technology Inc. Device 1242 Trying to pass them through to any domain is highly hit-or-miss. Seems like interrupt set-up fails quite often, but I have not been able to find any actual error-messages in any logs. The two first there are built-in to the motherboard, the last one is an add-in card. I have tried several other add-in cards for USB, all acting decidedly weird. _______________________________________________ Xen-devel mailing list Xen-devel@xxxxxxxxxxxxx http://lists.xen.org/xen-devel
