DESCRIPTION:Speaker: Geoff Huston\nToday’s Internet is so different from
  what we had imagined it would be some forty years ago. It connects billio
 ns of devices\, moves petabytes of data\, it operates trunk circuits at te
 rabits per second and the cost per delivered byte continues to drop. If th
 is was the ultimate promise of Moore’s Law and the silicon revolution\, 
 then the Internet is living that dream.\n\nBut it’s not what we thought 
 it would be. The rise of content distribution networks and the model of co
 ntent and service replication has brought about massive changes to the Int
 ernet’s architecture. By bringing service and content close to users\, t
 he network is bigger\, faster and cheaper\, but it’s also completely dif
 ferent to the Internet we started with.\n\nThis presentation will explore 
 these differences and what they mean to the future evolution of the Intern

DESCRIPTION:Speaker: Jana Dekanovska\nAI is a hot topic in cyber security.
  Everyone is curious about it. Excited about its use cases and nervous abo
 ut the problems it may cause in the wrong hands. AI as a tool can be used 
 by both defenders and adversaries. This talk will focus mainly on what the
  adversaries are doing from the offensive perspective and unpack the conce
 pt of Adversarial AI that will fundamentally change the threat landscape a
 nd lower the barrier of entry for adversaries to enter the cyber security 
 game.\n\nThe underlying openness of AI means that we can now take the coll
 ective knowledge of many smart people and bend the time and knowledge gap\
 , giving this advantage to the adversary\, creating threat actors that are
  smarter\, faster and have the ability to do more damage. AI is going to c
 hange the threats as we know them today and is the next big problem we are
  facing in security.\n\nJana will discuss how adversaries are using AI tod
 ay\, how it could be used in the future\, and how this will affect your bu
 siness.

DESCRIPTION:Speaker: Clinton Roy\nTLA+ is an implementation of Temporal Lo
 gic of Actions\, a specification language rooted in mathematical logic\, a
 llowing specifications to be manipulated and checked by mathematical tools
 . TLA+ can be used to design and document specifications in an unambiguous
  way\, and then the tooling around TLA+ can help prove that a system that 
 implements the specification can never go into an unknown state\, can't de
 adlock or livelock. \n\nOpen Source tends to be a source-first culture\, T
 LA+ offers a way of verifying the specification before even starting codin
 g. This year\, the Linux Foundation formed the TLA+ foundation to form an 
 Open foundation around TLA+ to foster development and use\, so it seems li
 ke a good time to introduce the language\, and the tooling around it.\n\nA
 ttendees should come away with a basic understanding of where TLA+ might b
 e useful in their engineering culture.

SUMMARY:Implementing the Kernel Memory Sanitizer for PowerPC

DESCRIPTION:Speaker: Nicholas Miehlbradt\nThe Kernel Memory Sanitizer (KMS
 AN) is a tool with the lofty goal of catching memory safety errors in the 
 Linux Kernel missed by most other memory sanitizers such as KASAN or KFENC
 E. In particular it can detect uses of uninitialized memory that may affec
 t the control flow of the kernel or leak information to user space. KMSAN 
 relies on close cooperation between the kernel and the compiler to correct
 ly instrument the various memory regions and play nice with the myriad of 
 ways the kernel stores data in and interacts with memory. Initially this t
 ool was only implemented on x86\, and I ambitiously set the goal of writin
 g the second public implementation for PowerPC (and got beaten to it by a 
 couple of weeks by s390). \n\nThis talk dives into the inner workings of K
 MSAN\, just how it manages to instrument every memory access and catch mem
 ory safety errors and give you surprisingly helpful error messages\, and t
 he challenges of truly making it work across multiple architectures.

DESCRIPTION:Speaker: Tejun Heo\nsched_ext is a new BPF extensible scheduli
 ng class for the Linux kernel. It allows implementing arbitrary schedulers
  in BPF and has a strong safety guarantee - a misbehaving scheduler may ma
 ke wrong scheduling decisions but can't crash the system. Enabling a new s
 cheduler is as simple as compling a BPF program and running the binary\, a
 nd the system can always safely be reverted to the builtin default kernel 
 scheduler. This capability to safely and quickly iterate scheduler impleme
 ntations radically speeds up both its development and deployment.\n\nCPUs 
 have been and continue to become more complex with both core count and top
 logy complexity increasing significantly\, which in turn substantially exp
 ands the scheduling problem space. one of sched_ext's main goals is enabli
 ng exploration of the scheduling problem space in a speedy\, safe and coll
 aborative manner. While sched_ext is in its very early stage\, we're alrea
 dy seeing sizable gains with production workloads in Meta from employing s
 trategies such as aggressive work-conservation\, soft-affinity and applica
 tion specific hinting.\n\nThis presentation takes a look at what sched_ext
  is\, how to use it and how it's starting to be employed in Meta fleet.\n\
 nsched_ext has not been merged into the upstream kernel yet. Please see ht

DESCRIPTION:Speaker: Trent Lloyd\nYour goal when benchmarking should be to
  ensure that the results are both continuously repeatable and fairly compa
 rable to other attempts (with or without changes to the system components 
 or configuration). While getting the biggest possible number is a fun and 
 favoured activity of those creating storage data sheets\, for bonus points
  we'll also try to get something more closely approximating your real work
 loads.\n\nBenchmarking of any kind often presents tricky business\, but st
 orage has always presented particularly difficult challenges as even Hard 
 Drives have interesting performance characteristics that vary greatly depe
 nding on workload. You might hope that was solved by SSDs\, and that is tr
 ue to an extent for real workloads\, but they tend to give even more misle
 ading results during synthetic benchmarks.\n\nOur case study is benchmarki
 ng both the individual components and over-all performance of a distribute
 d Ceph storage cluster. Don't worry if you're not using Ceph\, the majorit
 y of the content will apply equally well to any storage system\, but if yo
 u are then there are a few minutes of specific traps for Ceph clusters tha
 t we'll cover.\n\nYou'll walk away with an understanding of the many diffe
 rent factors getting in the way of great benchmarks including\n- Working s
 et size\n- Bi-modal SSD performance due to flash block management\n- Thin 
 provisioning\n- Bandwidth limitations of SSDs\, Backplanes\, PCIe buses\, 
 CPUs\, Memory and Networks\n- Measuring and identifying the actual bottlen
 eck you are hitting\n- Filesystems\n- Caches\n- Benchmarking tool configur

DESCRIPTION:Speaker: Gustavo A. R. Silva\nTrailing arrays at the end of a 
 structure are a common code construct in the Linux kernel. While they are 
 often dynamically-sized\, trailing arrays can also be fixed in size\, defi
 ned at compile-time and remaining constant throughout their lifetime.  It'
 s a little-known fact that compilers like GCC (and Clang) have historicall
 y treated all trailing arrays as if they were flexible in size. This appro
 ach becomes problematic if we want to rely on the compiler to detect out-o
 f-bounds issues on these arrays\, both at compile-time and run-time.\n\nTo
  effectively address this\, the compiler must first accurately differentia
 te between dynamically-sized and fixed-size trailing arrays. The introduct
 ion of the -fstrict-flex-arrays option in GCC 13 (and Clang 16) marks a si
 gnificant step towards this goal. Concurrently\, in Kernel Self-Protection
  Project\, we have been converting trailing zero-length and one-element ar
 rays --commonly known as fake flexible arrays-- into modern C99 flexible-a
 rray members for years.\n\nWe will see how the combination of these effort
 s\, along with the implementation of some crucial compiler attributes\, is
  paving the way towards eliminating out-of-bounds vulnerabilities on trail
 ing arrays in the upstream Linux kernel. Furthermore\, we will explore how
  this work is closely related to and contributes to the latest efforts in 
 hardening key APIs like memcpy()\, and in globally enabling options like -
 Warray-bounds.

  a RPI4 and a reverse engineered midi controller.\n\nThis year I'm happy t
 o have something far better: a fully open hardware and open source\, self 
 contained\, portable groovebox powered by a RaspberryPi foundation RP2040!
 \n\nAttendee’s do not need any prior knowledge or experience in trackers
 \, music making\, RP2040 or firmware development. However for those wantin
 g to build the picoTracker\, some basic experience in soldering will help 
 alot and for hacking on the firmware\, any C/C++ experience will go a long
  way. For those that just want to compose some music\, all you need is to 
 bring your curiosity and a creative spirit!\n\nAttendees of the workshop w
 ill get the opportunity to not only learn how to make music tracks using t
 he picoTracker\, but also learn how to hack on and install their own firmw
 are and even **optionally** build a picoTracker devices for themselves fro
 m kits that will be available for purchase\, with only some simple through
 -hole soldering required. I will also have some sets of RP Picos with audi
 o boards on breadboards for attendees to use and experiment with.\n\nFor a
 n additional charge\, those that would like to build a picotracker device 
 in the workshop from a parts kit or would like to purchase a pre-assembled
  kit\, please register your interest for ordering purposes using this form
 : https://forms.gle/tv7eHAi7rXTAR7Qq7\n\nThose building a kit or getting a
  pre-assembled device will also need to bring their own micro sdcard.\n\nI
 n the workshop\, we'll quickly cover the history of picoTracker's firmware
  and tracker-based music making in general\, before diving into the fun st
 uff of hacking on these cool devices.  All that will be needed from attend
 ees who want to participate in the software parts of the workshop will be 
 a laptop running preferably  Linux but a Macbook should work as well.\n\nF
 or those wanting to purchase a kit to build a picoTracker will need to bri
 ng a soldering iron\, though there will be 1 or 2 spare soldering irons fo
 r those that don't have their own.

DESCRIPTION:Speaker: Yifei Zhan\nExploring mobile linux security with Pine
 Phone Pro: OP-TEE security enclave\, \nVirtualization and beyond\n\nThe tr
 aditional security model of the desktop system is no longer suitable for \
 ntoday's threat landscape\, and there is a long road ahead until we can ha
 ve \nauditable and user-controlled mobile linux devices. This talk covers 
 my journey \nexploring Open Source Security Enclave\, Virtualization\, and
  alternative Operating \nSystem on the PinePhone Pro with focus on securit
 y improvement for mobile linux \ndevice.\n\nSecurity Enclave or Secure ele
 ment is a proven way to increase the security of a \ndevice against compro
 mised OS and/or hardware attack\, it works by isolating \nsensitive operat
 ions into a hardware backed secure environment with reduced \nattack surfa
 ce.\n\nThis technology is often used on mobile devices for user-hostile pu
 rposes such \nas DRM or lock-in\, and operates in a privileged state while
  being hard to audit \nby the user\, but this isn't always the case. With 
 OP-TEE\, it's possible to build \na Trusted Execution Environment that is 
 open to the user and auditable\, while \nfacilitating hardware-backed secu
 rity features. In the end this can make \nattacking an open source device 
 more expensive.\n\nI'm experimenting this with the PinePhone Pro as part o
 f a grant by Linux \nAustralia\, although the pinephone pro does not offer
  a complete hardware-backed \nchain-of-trust at the current stage\, it is 
 still an open and available platform \nfor exploring the way forward for s
 ecure linux mobile device and offers a \ntesting platform with realistic u
 se scenario.\n\n//////////// Slides Draft\n\nVerityMobile: Free and user f
 riendly mobile hardware security framework\n\nWhat is Security Enclave and
  Trusted Execution Environment (TEE) \nHow is TEE used by commercial vendo
 rs (Android/iOS)\nWhy do we need it? / How do we use it?\n  - Attack surfa
 ce reduction\n  - Increase overall security of a system\n  - Many other us
 e cases\n    Making Hardware more expensive to attack\, while remain open 
 and auditable\n\nPinePhone Pro: How does rk3399 boot?\n  - bootrom loads u
 -boot TPL into SRAM from SDcard\n  - TPL init DRAM\, return to bootrom\n  
 - bootrom load u-boot SPL\, which setup trustzone (fTPM)\n  - SPL then run
  proper U-boot and pass exec to kernel\n\nPinePhone Pro: The Missing Root 
 of Trust\n  - Possible new hardware revision?\n\nUse Case for security enc
 lave:\n\n-  Hardware backed TLS crypto engine\n   Work with OpenSSL/OpenVP
 N\n\n- Passkey with practially unlimited key storage\n   Using fTPM to sea
 l passkey identity\n    It's still more secure than password even without 
 proper root of trust\, easy to rotate\, hard to clone\n\n- TPM and measure
 d boot\n\n- Auto decrypt root disk with key from TPM\n\n- Near-field and r
 emote attestation\n   U-Boot can interact with fTPM to perform measured bo

DESCRIPTION:Speaker: David Gibson\nContainers have become the go to approa
 ch for deploying and isolating software.  They give the illusion of a full
  system managed by the\napplication\, while actually allowing a host to ru
 n many isolated things.  Virtual Machines\, which preceded containers and 
 still have uses today\, achieve a similar result in a different way.\n\nIn
  both cases the underlying technology (namespaces\, CPU virtualisation) ca
 n be freely used by a non-privileged user\, so in theory it should be best
  practice to run containers and VMs without root.  But\, most guests need 
 a network connection to the outside world\, and so far that's required one
  of two choices:\n\n 1) The guest can be attached to a network interface r
 outed through the host kernel.  That works well\, but requires root on the
  host\, or at least some kind of administratively privileged helper infras
 tructure.\n\n 2) Use a "rootless" network.  This approach\, typically base
 d on libslirp\, can be used without administrative assistance\, but has po
 or performance\, requires awkward NAT and has other limitations.\n\nSo\, n
 etworking requiring privileged setup has been the norm for all production 
 deployments of both containers and VMs\, with rootless networks relegated 
 to "quick and dirty" testing and experimental jobs.\n\nIn the last two yea
 rs\, Stefano Brivio and myself have written passt & pasta.  While superfic
 ially similar to Slirp\, these tools are dramatically faster (usually 10 o
 r more times the throughput)\, don't require NAT and have a generally more
  modern and robust design.  This makes rootless networking practical for p
 roduction cases\, not just experiments and tests.\n\nThis talk describes h
 ow this can be used to build practical rootless networks today using integ
 ration with tools like Podman and libvirt\nand examines some of the use ca
 ses that this now allows.

DESCRIPTION:Speaker: Vik Olliver\nIf you're in a situation where you can't
  use a keyboard\, mouse\, or touchscreen\, it's very hard to be a part of 
 our digital society. The Quirkey keyboard takes its accessibility cues fro
 m 80's when Microwriter developed an effective typing system using a keybo
 ard with 5 main tactile keys\, one for each digit - arm movement and visio
 n not required. Their device was expensive\, somewhat clunky due to the te
 chnology of the day\, proprietary\, patented up to the eyeballs\, and fina
 lly orphaned in a dysfunctional venture capital disaster. But the patents 
 have long expired\, and Vik wrote the original PC keyboard drivers...\n\nQ
 uirkey re-implements the system Microwriter painstakingly developed. It's 
 now a palm-sized\, driverless HID keyboard device made using 3D printing a
 nd off the shelf Open Source hardware. The result is cheap\, customizable\
 , Open in every way\, and thanks to all the above\, easy to make in any mo
 dest Maker Space. This presentation covers creating a custom parametric 3D
  printed shell in OpenSCAD\, and making firmware that runs on more or less
  any Arduino/Pico/ESP32 with USB or Bluetooth HID. You'll also see how the
  typing system works\, and the not insubstantial improvements that have be
 en made to the original 80's design.\n\nA cool hardware project does not m
 ake a product though\, and the author wishes to share the lessons learned 
 in creating the user-friendly documentation\, training systems\, and maker
 -friendly technical packages needed to turn a project into a product that 
 can change people's lives.

 s currently use a mechanism called the\ndouble-write buffer\, where they w
 rite a complete 8K/16K chunk to their own\njournal before performing an ac
 tual write to the disk\, however this comes at a\ncost of major performanc
 e hit of as much as 30% in extreme cases.  This\ndouble-write is required 
 by DBs to provide crash consistency (in case if the\ncrash happens in the 
 middle of the write). However\, it can be avoided if the\nstack supports a
 tomic writes (both device and OS stack). \n\nWe've now started seeing devi
 ces which can perform such multi kilobytes atomic\nwrites but Linux still 
 needs work before it can support atomic writes.\nCurrently there is a prop
 osal from the community to enable atomic writes for\nDIRECT-IO on XFS\, ho
 wever there are problems when it comes down to supporting\natomic writes f
 or buffered-io (e.g. postgres uses buffered-io).\n\nIn this talk we would 
 like to go over the why databases would benefit from atomic\nwrites\, the 
 challenges involved in implementing them in Linux and the\nwork done so fa
 r. We have a working prototype implemented for doing atomic\nwrite extent 
 allocations in ext4 for direct-io. Next we are looking to leverage\n64K pa
 gesize of Power (or using large folio support for other archs)\, to\nproto

DESCRIPTION:Speaker: Ricardo Sueiras\nAuthorization is one of the foundati
 onal needs when building your applications and services. Making sure you a
 re able to correctly and reliably grant or deny  access to your applicatio
 n resources is critical. Yet this is still one of the hardest things we ha
 ve to do as developers. \n\n In this session I am going to cover a new ope
 n source project called Cedar that helps you solve this problem and build 
 next generation authorization into your applications. Developed with autom
 ated reasoning and differential testing\, I am going to provide a quick ov
 erview of Cedar\, and then showing you with a simple demo how you can begi
 n to use Cedar to help you simplify authorisation for your applications.

DESCRIPTION:Speaker: Nicholas Piggin\nOne of the components of a firmware 
 stack is a BIOS. The runtime BIOS provides abstraction for services and co
 ntrols to low level hardware\, to the operating system. The runtime BIOS c
 omponent of OpenPOWER systems is called OPAL.\n\nAlthough IBM OpenPOWER sy
 stems have an entirely open-source firmware stack and OPAL is an open spec
 ification\, it resembles a traditional runtime BIOS interface where a BIOS
  call is a big-hammer operation that causes the operating system to lose c
 ontrol of the CPU while it runs rather opaque code in a special mode\, bef
 ore returning control to the OS.\n\nACPI addresses some of the limitations
  of such interfaces by providing bytecode that can be run by the operating
  system\, however this approach seems to be designed for proprietary firmw
 are and binary blobs. Can we do better with a ground-up design for open-so
 urce firmware and operating systems? Can eBPF save the day? In this talk I
  will present some findings of my investigations into answering these ques
 tions.

 es to keep up.  Learn how\nFreeIPA and SSSD have grown support for FIDO2 p
 asskeys and for\nauthenticating users from external OAuth 2.0 identity pro
 viders.\nThere will be demos!\n\nAuthentication is a critical aspect of ho
 st\, network and\norganisational security.  Identity management systems li
 ke FreeIPA\ncentralise your identities and access policies\, to help you m
 eet\nyour security and compliance requirements.\n\nHistorically and up to 
 the present day\, passwords were widely used\nfor initial user authenticat
 ion.  But in the current era a healthy\nsecurity posture often demands 2FA
 \, hardware cryptographic tokens\,\nconsumption of identity assertions fro
 m third party providers\, or\nsome combination of these.  Major trends in 
 the web authentication\nlandscape include *Passkeys*\, and delegation of a
 uthentication to\nthird-parties (sometimes called "Web SSO").\n\n*Passkeys
 * is a convenient\, passwordless\, phishing-resistant\nauthentication tech
 nology based on FIDO Alliance standards.  It uses\npublic key cryptography
  and the credential can be implemented in\nsoftware or hardware.\n\n*OAuth
  2.0* is an access delegation protocol widely used on the web.\nYou have p
 robably seen services that offer "Log in with {popular\nsite}".  When you 
 use these options\, OAuth 2.0 (or the OpenID\nConnect protocol which build
 s upon it) are what happens behind the\nscenes.  OAuth 2.0 also support no
 n-web applications via the *Device\nauthorisation grant* flow.\n\nRecent r
 eleases of FreeIPA and its client-side companion SSSD added\nsupport for b
 oth of these authentication technologies.  In this\npresentation I will re
 view how these mechanisms work\, and describe\nwhat had to be added or cha
 nged in FreeIPA and SSSD to support them.\nAttendees will learn\, via prac
 tical demonstrations\, how to configure\ntheir own systems and networks to
  use these modern\, secure\nauthentication mechanisms.

DESCRIPTION:Speaker: Paul McKenney\nThe term "heisenbug" was inspired by t
 he Heisenberg Uncertainty Principle from quantum physics\, which states th
 at it is impossible to exactly quantify a given particle’s position and 
 velocity at any given point in time. Any attempt to more accurately measur
 e that particle's position will result in increased uncertainty of its vel
 ocity and vice versa. Similarly\, attempts to track down the heisenbug cau
 ses its symptoms to radically change or even disappear completely [1].\n\n
 If the field of physics inspired the name of this problem\, it is only fai
 r that the field of physics should inspire the solution. Fortunately\, par
 ticle physics is up to the task: Why not create an anti-heisenbug to annih
 ilate the heisenbug? Or\, perhaps more accurately\, to annihilate the heis
 en-ness of the heisenbug? Although producing an anti-heisenbug for a given
  heisenbug is more an art than a science\, this talk will cover ways of do
 ing just that.\n\n[1] The term “heisenbug” is a misnomer\, as most hei
 senbugs are fully explained by the observer effect from classical physics.
  Nevertheless\, the name has stuck.

 r looking at your IT landscape. Remove the rose tinted spectacles and see 
 large parts of your infrastructure for what it really is\, a rusty blunt a
 xe\, rather than a precision engineered carbon\, or perhaps silicon\, edge
 d beauty.\n\nWe regularly use analogies as a way to make technological shi
 fts easier for organisations to understand. Most recently we’ve used “
 Cattle vs Pets” for our recent shift towards immutable infrastructure an
 d Dev/Ops centric patterns. One problem is not all IT is moving at the spe
 ed of automation\, and I often see references to “Stone Age” systems o
 r processes.\n\nSo after roughly 30 years in the IT industry I keep coming
  back to one key concept. Almost everything can be explained if you treat 
 its origin as a “Dwarf Axe”. Whilst businesses continue to have a grea
 t many fragile “snowflake” services\, core systems are often large\, r
 obust and need to operate for a very long time\, effectively the “Axe”
  of IT. Like a “Dwarf Axe” they survive for generations as they are ha
 nded from team to team.\n\nWe’ll look at some “IT” war stories and s
 ee how much progress we’ve really made from the early days of the “sto
 ne axe”. Do alternative approaches make sense such as microservices (arr
 ows) or serverless (throwing stars)? Can you really afford that fancy new 
 system (chainsaw)\, maybe your axe simply  needs sharpening\, perhaps your
  axe just requires a new head or arm\, or do you even need an axe any more
 ?\n\nYou might completely disagree\, or occasionally nod your head in agre
 ement\, but I guarantee you’ll never look at your IT landscape the same 
 way ever again.

 nd right to repair laws its easy to forget how open hardware really used t
 o be. Recently I was made all too aware of this when I chose to Circuit Be
 nd a 80's era Video editor and without much effort was able to find comple
 te schematics and component lists.\n\nThis is a stark contrast to modern h
 ardware and even the modern circuit bending community where generally ther
 e is very little information available around how to repair or modify hard
 ware\n\nWith all that as a preface I will spend much of this talk explaini
 ng my approach to circuit bending and how I was able to use the openness o
 f the hardware to my advantage. As someone with a limited understanding of
  electronics\, circuit bending is an excersize in educated guessing combin
 ed with a whole lot of hope and significant levels of surprise when you ac
 tually end up with something cool. The open hardware of the 1980's makes t
 his whole process significantly more educated and maybe slightly less gues
 sy. Having access to service manuals made it simple for someone with limit
 ed knowledge such as myself to take a crazy idea and actually somewhat pul
 l it off.\n\nAlongside talking about the project I've worked on i'll cover
  some other simple designs for people who'd like to get started along with
  highlighting some of the other people doing significant work in this fiel
 d. Of course there will also be a fair share of glitchy video demo's.

 ernel\, it provides core mechanisms for securely multiplexing the hardware
 \, but none of the services application programmers expect\, so adopters a
 re forced to develop those themselves. Furthermore\, a high level of exper
 tise is required to design performant systems on top of seL4. The result i
 s frequently a poor design\, and far too often people giving up.\n\nThe Tr
 ustworthy Systems team at UNSW has now decided to build Lions OS\, a compl
 ete seL4-based OS aimed to support the needs of developers of cyberphysica
 l\, IoT and other embedded systems. Lions OS\, named after John Lions (of 
 Lions Book fame\, arguably one of the fathers of open source)\, is being d
 esigned and implemented from scratch\, with the seemingly conflicting goal
 s of high performance\, high security and adaptability to a wide class of 
 use cases. Specifically we plan to prove the correct implementation of its
  critical components.\n\nIn the talk I will explain why I think this is no
 t only achievable\, but will be achieved within 2-3 years\, by strictly ad
 hering to the time-honoured engineering principle KISS – keep it simple\
 , stupid! I will present our initial results that show that\, with the rig
 ht design\, this simplicity can not only achieve excellent performance (ou
 tperforming Linux networking by a factor three) but also enable proofs of 
 implementation correctness. By the time of the conference\, an initial rel
 ease (of limited functionality but reasonable maturity) will have been mad

  flow chain is simplified by having a Unified boot-flow on such SoCs. The 
 optimized boot-flow involves using u-boot bootloader / firmware to load ei
 ther Linux directly or load GRUB as an EFI application\, which can be furt
 her used to boot Linux or RTOS flavors.\n\nThis session intends to provide
  a general status update and a discussion about ongoing / upcoming activit
 ies. I will also talk about the challenges faced so far and what lies ahea
 d.\n\nThis session will also touch on how to boot a Unified upstream kerne
 l + debian user-space on multiple Robotics boards now - thus promoting cod
 e sharing and allowing for easier maintainability.\n\nI will also talk in 
 brief about how u-boot drivers were written or ported for such platforms u
 sing one of the more recent Qualcomm boards as an example.

 alia\, but we're right behind e-bikes and scooters.     Rental schemes abo
 und in larger cities\, and the sight of a person in \nwork clothes zooming
  along on a scooter or bike is commonplace.\n\nUnlike an electric car\, bi
 kes and scooters are so simple you can build and fix them yourself.    An 
 electric scooter off the shelf costs over $500\, bikes can be several thou
 sand\, and mobility aids and wheelchairs can be tens of thousands.    And 
 then you might be left with a doorstop the first time they break down.\n\n
 So lets look at how to assemble your own from parts -- the five key parts 
 of a micromobility vehicle are the motor\, the frame \, the motor\, the ba
 ttery\,  the battery management computer and the speed controller.     Tho
 se last four all have open source options that lead the field.

DESCRIPTION:Speaker: Changwoo Min\nHow does task scheduling impact Linux g
 aming? For example\, suboptimal task scheduling can cause stuttering while
  playing games on the Steam Deck game console. In this talk\, we will shar
 e our journey to optimize the scheduler for Linux gaming. We first began b
 y questioning how to define and measure the stuttering problem to quantify
  the impact of scheduler optimization. We then extensively analyzed the ch
 aracteristics of game tasks from the scheduler’s point of view. Characte
 rizing task behavior in Linux gaming helps to understand why some schedule
 rs create much stuttering and others create less. Lastly\, we will share o
 ur progress on the optimized scheduler for reducing the stuttering problem
 s in Linux gaming. We implemented the scheduling policy based on sched_ext
 \, a BPF-based extensible scheduling framework.
