True. I introduced the lzma code in coreboot (back when it was called
LinuxBIOS) when we were working on OLPC XO-1 support.

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.

A size benefit for the resulting image is a good reason to switch.

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.

Re: [SeaBIOS] [PATCH 0/6] qemu: add bochs-display support
by Patrick Rudolph
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.
Regards,
Patrick

Re: [SeaBIOS] SecureDrive

I guess it is not possible.. Found this article on vendor site

"JetFlash series aims at being a portable storage device and not as a

I'm having problems with USB boot from Transcend JetFlash 620 drive 32GB.
SeaBIOS doesn't see it as boot device. I suppose the problem is in
SecureDrive technology that is used on this device. I tried to remove it
with "CD-ROM Remover_v1.0.0.3" tool that I've found. It removed CD partition
from OS, but SeaBIOS still can't see flash drive as boot device.
Does someone know how to solve this issue?

Re: [SeaBIOS] Librem 15v3 hangs at Booting from Hard Disk...

This is clearly totally unrelated to SeaBIOS, and it looks like an
linux/grub installation problem.

If you see nothing after that, then that probably means that SeaBIOS
executed whatever was on the drive's boot sector and that failed to do
anything, so grub crashed or there was no grub in the first place, or
it was misconfigured and it stopped instead of showing some error
message, etc.. whatever the issue is, it looks like it's not related
to SeaBIOS.

What OS is that ? 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.

Yeah, upgrading coreboot won't change anything if your hard drive
doesn't have a working grub installed on it.
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)

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.

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.

bug: boot menu items 10+ cannot be selected
by Ian Kelling
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.
