KVM Forum 2016: Call For Participation
August 24-26, 2016 - Westin Harbor Castle - Toronto, Canada
(All submissions must be received before midnight May 1, 2016)
=================================================================
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 2016.
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. As we celebrate ten years
of KVM development in the Linux kernel, KVM continues to be a
critical part of the FOSS cloud infrastructure.
This year, KVM Forum is joining LinuxCon and ContainerCon in Toronto,
Canada. Selected talks from KVM Forum will be presented on Wednesday
August 24 to the full audience of LinuxCon and ContainerCon. Also,
attendees of KVM Forum will have access to all of the LinuxCon and
ContainerCon talks on Wednesday.

SUBMITTING YOUR PROPOSAL
===============
Abstracts due: May 1, 2016
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 May 27, 2016.
Speakers will receive a complimentary pass for the event. In the instance
that your submission has multiple presenters, only the primary speaker for a
proposal will receive a complementary 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_2016_BOF
Let people you think might be interested know about it, 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 abstract. We will request full
biographies if a panel is accepted.

QEMU provides two fw_cfg files to support IGD. The first holds the
OpRegion data which holds the Video BIOS Table (VBT). This needs to
be copied into reserved memory and the address stored in the ASL
Storage register of the device at 0xFC offset in PCI config space.
The OpRegion is generally 8KB. This file is named "etc/igd-opregion".
The second file tells us the required size of the stolen memory space
for the device. This is a dummy file, it has no backing so we only
allocate the space without copying anything into it. This space
requires 1MB alignment and is generally either 1MB or 2MB, depending
on the hardware config. If the user has opted in QEMU to expose
additional stolen memory beyond the GTT (GGMS), the GMS may add an
additional 32MB to 512MB. The base address of the reserved memory
allocated for this is written back to the Base Data of Stolen Memory
register (BDSM) at PCI config offset 0x5C on the device. This file is
named "etc/igd-bdsm".

v4: Back to a single patch thanks to Kevin's suggestion to use
memalign_tmphigh() for larger allocations. Now creating
reserved space for stolen memory and writing the value to
the BDSM register is queued off the existence of a fw_cfg
file, just like the OpRegion. The only difference is that
we don't copy the contents, just use the meta data.

It's interesting that newer compilers accept the 'int i' declaration
inside of for loops - I didn't realize that was allowed in C99. In
any case, I pulled the declaration outside the loop to suppress the
error, and I committed the change.
