Do you have any numbers for this? An improved compression ratio and improved speed would be nice indeed, but how does the size of the decompression code change? If the decompression code grows more than the size reduction from better compression, it would be a net loss. A significantly reduced decompression speed would also be a problem. Decompression speed would have to be measured both for stream decompression (i.e. the decompressor gets the compressed data in single-byte or multibyte chunks) as well as full-size decompression (i.e. the decompressor can access all compressed data at once). We also have to make sure that stream decompression still works after the change. > Do you think it should be done, or you are OK with using such an > outdated version? A size benefit for the resulting image is a good reason to switch. Regards, Carl-Daniel

KVM Forum 2018: Call For Participation
by Paolo Bonzini June 12, 2018

June 12, 2018

================================================================ KVM Forum 2018: Call For Participation October 24-26, 2018 - Edinburgh International Conference Centre - Edinburgh, UK (All submissions must be received before midnight June 14, 2018) ================================================================= KVM Forum is an annual event that presents a rare opportunity for developers and users to meet, discuss the state of Linux virtualization technology, and plan for the challenges ahead. We invite you to lead part of the discussion by submitting a speaking proposal for KVM Forum 2018. At this highly technical conference, developers driving innovation in the KVM virtualization stack (Linux, KVM, QEMU, libvirt) can meet users who depend on KVM as part of their offerings, or to power their data centers and clouds. KVM Forum will include sessions on the state of the KVM virtualization stack, planning for the future, and many opportunities for attendees to collaborate. After more than ten years of development in the Linux kernel, KVM continues to be a critical part of the FOSS cloud infrastructure. This year, KVM Forum is joining Open Source Summit in Edinburgh, UK. Selected talks from KVM Forum will be presented on Wednesday October 24 to the full audience of the Open Source Summit. Also, attendees of KVM Forum will have access to all of the talks from Open Source Summit on Wednesday. https://events.linuxfoundation.org/events/kvm-forum-2018/program/cfp/ Suggested topics: * Scaling, latency optimizations, performance tuning, real-time guests * Hardening and security * New features * Testing KVM and the Linux kernel: * Nested virtualization * Resource management (CPU, I/O, memory) and scheduling * VFIO: IOMMU, SR-IOV, virtual GPU, etc. * Networking: Open vSwitch, XDP, etc. * virtio and vhost * Architecture ports and new processor features QEMU: * Management interfaces: QOM and QMP * New devices, new boards, new architectures * Graphics, desktop virtualization and virtual GPU * New storage features * High availability, live migration and fault tolerance * Emulation and TCG * Firmware: ACPI, UEFI, coreboot, U-Boot, etc. Management and infrastructure * Managing KVM: Libvirt, OpenStack, oVirt, etc. * Storage: Ceph, Gluster, SPDK, etc.r * Network Function Virtualization: DPDK, OPNFV, OVN, etc. * Provisioning =============== SUBMITTING YOUR PROPOSAL =============== Abstracts due: June 14, 2018 Please submit a short abstract (~150 words) describing your presentation proposal. Slots vary in length up to 45 minutes. Also include the proposal type -- one of: - technical talk - end-user talk Submit your proposal here:http://events.linuxfoundation.org/cfp Please only use the categories "presentation" and "panel discussion" You will receive a notification whether or not your presentation proposal was accepted by August 10, 2018. Speakers will receive a complimentary pass for the event. In the instance that case your submission has multiple presenters, only the primary speaker for a proposal will receive a complimentary event pass. For panel discussions, all panelists will receive a complimentary event pass. TECHNICAL TALKS A good technical talk should not just report on what has happened over the last year; it should present a concrete problem and how it impacts the user and/or developer community. Whenever applicable, focus on work that needs to be done, difficulties that haven't yet been solved, and on decisions that other developers should be aware of. Summarizing recent developments is okay but it should not be more than a small portion of the overall talk. END-USER TALKS One of the big challenges as developers is to know what, where and how people actually use our software. We will reserve a few slots for end users talking about their deployment challenges and achievements. If you are using KVM in production you are encouraged submit a speaking proposal. Simply mark it as an end-user talk. As an end user, this is a unique opportunity to get your input to developers. HANDS-ON / BOF SESSIONS We will reserve some time for people to get together and discuss strategic decisions as well as other topics that are best solved within smaller groups. These sessions will be announced during the event. If you are interested in organizing such a session, please add it to the list at http://www.linux-kvm.org/page/KVM_Forum_2018_BOF Let people you think who might be interested know about your BOF, and encourage them to add their names to the wiki page as well. Please try to add your ideas to the list before KVM Forum starts. PANEL DISCUSSIONS If you are proposing a panel discussion, please make sure that you list all of your potential panelists in your the abstract. We will request full biographies if a panel is acceped. =============== HOTEL / TRAVEL =============== This year's event will take place at the Edinburgh International Conference Centre.

Re: [SeaBIOS] [PATCH 0/6] qemu: add bochs-display support
by Patrick Rudolph May 31, 2018

May 31, 2018

Patch 2, 4 and 5 looks good to me. Patch 6 causes artifacts on mode change, if the new mode is smaller than the previous. Would it be possible to include a 32bit memset into seavgabios ? That way there is no need to call a BIOS routine to clear the memory.

What's the error of update-initramfs ? Did you try to run update-initramfs manually to see what error it gives you ? I remember seeing a similar error related to a busybox depedency (this error https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=864143) and I can't remember the exact fix, but it was something like : edit /etc/initramfs-tools/initramfs.conf and change the "BUSYBOX=auto" to either "y" or "n", one of them fixes it. Or maybe it was the file /usr/share/initramfs-tools/conf-hooks.d/cryptsetup, or maybe you have to add a line "BUSYBOXDIR=/bin" to the config.. Either way, you should fix whatever is causing that first. > > I have upgraded coreboot, no joy.

I think your issue here might be that "update-grub2" will update the grub files in /boot (from the live USB), not in /mnt/root/boot. I would suggest to simplify your life and just "mount /dev/sda1 /boot" so the update would work (even if you manually use grub-mkconfig -o /mnt/root/boot, it will still scan some things in /boot, and it might mess things up, so just mount it on top of the existing /boot and call update-grub) > The folks at purism/librem seem to be as confused as I am. Does anyone here > have any insight into how I can fix this problem? I haven't heard of this issue, usually, if it's related to coreboot, I get asked for my opinion, but I suppose I wasn't poked about it by tech support because it's a linux/install problem, and indeed, it's not related to coreboot. As for all that stuff about getting seabios debug, I don't know how much that will help you. I'm sure all you'll see is something like "jumping into boot sector" then nothing, it's not like the cbmem console log will have the grub debug output in it saying "I'm about to crash because I can't find my config" for example. Unless SeaBIOS sets up a segfault handler or something prior to jumping into boot drive and writes to the log a crash report, I have no idea if it does that. > > Thanks! > I hope that helps, good luck. And if you need more help, I suggest not to spam this mailing list with non-seabios-development related questions, you can continue emailing me directly. Youness.

bug: boot menu items 10+ cannot be selected
by Ian Kelling May 15, 2018

May 15, 2018

The boot menu says option 10, but when you type 10, it selects #1 as soon as you press 1. I think an easy fix would be that when there are at least 10 items in the boot menu to print 01, 02, etc. and read 2 characters. I don't care about this being fixed, just figured I'd report it. -- Ian Kelling https://iankelling.org
