LAS16-111: Easing Access to ARM TrustZone – OP-TEE and Raspberry Pi 3Linaro
LAS16-111: Raspberry Pi3, OP-TEE and JTAG debugging
Speakers:
Date: September 26, 2016
★ Session Description ★
ARM TrustZone is a critical technology for securing IoT devices and systems. But awareness of TrustZone and its benefits lags within the maker community as well as among enterprises. The first step to solving this problem is lowering the cost of access. Sequitur Labs and Linaro have joined forces to address this problem by making a port of OP-TEE available on the Raspberry Pi 3. The presentation covers the value of TrustZone for securing IoT and how customers can learn more through this joint effort.
Embedded systems security remains a challenge for many developers. Awareness of mature, proven technologies such as ARM TrustZone is very low among the Maker community as well as among enterprises. As a result this foundational technology is largely being ignored as a security solution. Sequitur Labs and Linaro have taken an innovative approach combining an Open Source solution – OP-TEE with Raspberry Pi 3. The Raspberry Pi 3 is one of the world’s most popular platforms among device makers. Its value as an educational tool for learning about embedded systems development is proven.
Sequitur Labs have also enabled bare metal debugging via JTag on the Pi 3 enhancing the value of the Pi 3 as an educational tool for embedded systems development.
The presentation will focus on
ARM v8a architecture and instruction set

Innovating Inference - Remote Triggering of Large Language Models on HPC Clus...Globus
Large Language Models (LLMs) are currently the center of attention in the tech world, particularly for their potential to advance research. In this presentation, we'll explore a straightforward and effective method for quickly initiating inference runs on supercomputers using the vLLM tool with Globus Compute, specifically on the Polaris system at ALCF. We'll begin by briefly discussing the popularity and applications of LLMs in various fields. Following this, we will introduce the vLLM tool, and explain how it integrates with Globus Compute to efficiently manage LLM operations on Polaris. Attendees will learn the practical aspects of setting up and remotely triggering LLMs from local machines, focusing on ease of use and efficiency. This talk is ideal for researchers and practitioners looking to leverage the power of LLMs in their work, offering a clear guide to harnessing supercomputing resources for quick and effective LLM inference.
First Steps with Globus Compute Multi-User EndpointsGlobus
In this presentation we will share our experiences around getting started with the Globus Compute multi-user endpoint. Working with the Pharmacology group at the University of Auckland, we have previously written an application using Globus Compute that can offload computationally expensive steps in the researcher's workflows, which they wish to manage from their familiar Windows environments, onto the NeSI (New Zealand eScience Infrastructure) cluster. Some of the challenges we have encountered were that each researcher had to set up and manage their own single-user globus compute endpoint and that the workloads had varying resource requirements (CPUs, memory and wall time) between different runs. We hope that the multi-user endpoint will help to address these challenges and share an update on our progress here.

Climate Science Flows: Enabling Petabyte-Scale Climate Analysis with the Eart...Globus
The Earth System Grid Federation (ESGF) is a global network of data servers that archives and distributes the planet’s largest collection of Earth system model output for thousands of climate and environmental scientists worldwide. Many of these petabyte-scale data archives are located in proximity to large high-performance computing (HPC) or cloud computing resources, but the primary workflow for data users consists of transferring data, and applying computations on a different system. As a part of the ESGF 2.0 US project (funded by the United States Department of Energy Office of Science), we developed pre-defined data workflows, which can be run on-demand, capable of applying many data reduction and data analysis to the large ESGF data archives, transferring only the resultant analysis (ex. visualizations, smaller data files). In this talk, we will showcase a few of these workflows, highlighting how Globus Flows can be used for petabyte-scale climate analysis.
In software engineering, the right architecture is essential for robust, scalable platforms. Wix has undergone a pivotal shift from event sourcing to a CRUD-based model for its microservices. This talk will chart the course of this pivotal journey.
Event sourcing, which records state changes as immutable events, provided robust auditing and "time travel" debugging for Wix Stores' microservices. Despite its benefits, the complexity it introduced in state management slowed development. Wix responded by adopting a simpler, unified CRUD model. This talk will explore the challenges of event sourcing and the advantages of Wix's new "CRUD on steroids" approach, which streamlines API integration and domain event management while preserving data integrity and system resilience.
Participants will gain valuable insights into Wix's strategies for ensuring atomicity in database updates and event production, as well as caching, materialization, and performance optimization techniques within a distributed system.
Join us to discover how Wix has mastered the art of balancing simplicity and extensibility, and learn how the re-adoption of the modest CRUD has turbocharged their development velocity, resilience, and scalability in a high-growth environment.

How to Position Your Globus Data Portal for Success Ten Good PracticesGlobus
Science gateways allow science and engineering communities to access shared data, software, computing services, and instruments. Science gateways have gained a lot of traction in the last twenty years, as evidenced by projects such as the Science Gateways Community Institute (SGCI) and the Center of Excellence on Science Gateways (SGX3) in the US, The Australian Research Data Commons (ARDC) and its platforms in Australia, and the projects around Virtual Research Environments in Europe. A few mature frameworks have evolved with their different strengths and foci and have been taken up by a larger community such as the Globus Data Portal, Hubzero, Tapis, and Galaxy. However, even when gateways are built on successful frameworks, they continue to face the challenges of ongoing maintenance costs and how to meet the ever-expanding needs of the community they serve with enhanced features. It is not uncommon that gateways with compelling use cases are nonetheless unable to get past the prototype phase and become a full production service, or if they do, they don't survive more than a couple of years. While there is no guaranteed pathway to success, it seems likely that for any gateway there is a need for a strong community and/or solid funding streams to create and sustain its success. With over twenty years of examples to draw from, this presentation goes into detail for ten factors common to successful and enduring gateways that effectively serve as best practices for any new or developing gateway.

Providing Globus Services to Users of JASMIN for Environmental Data AnalysisGlobus
JASMIN is the UK’s high-performance data analysis platform for environmental science, operated by STFC on behalf of the UK Natural Environment Research Council (NERC). In addition to its role in hosting the CEDA Archive (NERC’s long-term repository for climate, atmospheric science & Earth observation data in the UK), JASMIN provides a collaborative platform to a community of around 2,000 scientists in the UK and beyond, providing nearly 400 environmental science projects with working space, compute resources and tools to facilitate their work. High-performance data transfer into and out of JASMIN has always been a key feature, with many scientists bringing model outputs from supercomputers elsewhere in the UK, to analyse against observational or other model data in the CEDA Archive. A growing number of JASMIN users are now realising the benefits of using the Globus service to provide reliable and efficient data movement and other tasks in this and other contexts. Further use cases involve long-distance (intercontinental) transfers to and from JASMIN, and collecting results from a mobile atmospheric radar system, pushing data to JASMIN via a lightweight Globus deployment. We provide details of how Globus fits into our current infrastructure, our experience of the recent migration to GCSv5.4, and of our interest in developing use of the wider ecosystem of Globus services for the benefit of our user community.
SOCRadar Research Team: Latest Activities of IntelBrokerSOCRadar
The European Union Agency for Law Enforcement Cooperation (Europol) has suffered an alleged data breach after a notorious threat actor claimed to have exfiltrated data from its systems. Infamous data leaker IntelBroker posted on the even more infamous BreachForums hacking forum, saying that Europol suffered a data breach this month.
The alleged breach affected Europol agencies CCSE, EC3, Europol Platform for Experts, Law Enforcement Forum, and SIRIUS. Infiltration of these entities can disrupt ongoing investigations and compromise sensitive intelligence shared among international law enforcement agencies.
However, this is neither the first nor the last activity of IntekBroker. We have compiled for you what happened in the last few days. To track such hacker activities on dark web sources like hacker forums, private Telegram channels, and other hidden platforms where cyber threats often originate, you can check SOCRadar’s Dark Web News.

3. ACPI Support In Windows
Overview
Windows Vista requires ACPI
Non-ACPI HALs are not available in Windows Vista
Legacy power management and BIOS configuration
implementations are no longer supported
Both ACPI and Windows have seen
continual advancements
ACPI offers significant system advantages
Close platform integration with the operating system
Greatly increased reliability, diagnosability
Windows ACPI support promotes
faster system development
Rich ACPI feature support
Extensive ACPI debugging support
ACPI table overload for rapid system bring-up
4. ACPI Support In Windows
Microsoft ASL compiler update
Updated ASL compiler now available
Version 3.0.0 released
Supports ACPI 2.0, 3.0 objects required for Windows Vista
Provides several features to facilitate development
and debugging
Saves ACPI tables from firmware to disk file
Un-assembling AML into ASL
Loading ACPI tables from disk, bypassing BIOS ROMs
See details later in this presentation
Available for download from Windows Hardware
and Driver Central (WHDC)
http://go.microsoft.com/fwlink/?LinkId=66535
5. ACPI In Windows Vista
ACPI version support
Windows Vista supports select objects
from ACPI 2.0, 3.0 specifications
Windows operating systems typically do not
support all features of any one version
of the ACPI specification
Key elements from ACPI are selected to support
development of emerging hardware, e.g.
PCI Express
Mobile dual core processors
High Performance Event Timers (HPET)
6. ACPI In Windows Vista
Using RSDT versus XSDT
In Windows Vista, if the RSDP Revision field is > 2
Windows will use the XSDT in place of the RSDT
Windows will calculate the checksum of the entire RSDP
Must match the Extended Checksum field
Ensure your XSDT address is valid if you report
Revision > 2 in the RSDP
Leverage the RSDP to support both older
and newer operating systems
RSDT can point to tables with older version support
XSDT points to newer tables
7. ACPI In Windows Vista
FADT implementation details
If the FADT Revision field is > 2,
Windows Vista will use the extended
64-bit addresses in the FADT
X_FIRMWARE_CTRL and X_DSDT
Extended addresses of ACPI fixed hardware
X_PM1a_EVT_BLK, etc.
DSDT Revision field is used to enable
ACPI 2.0 and greater interpreter support
A Revision > 1 enables interpreter support
for ACPI 2.0 and greater
All integers are treated as 64-bit in ASL
8. ACPI In Windows Vista
ACPI interpreter support
The Windows Vista AML interpreter features
expanded implicit source data type conversion
Only enabled for a subset of opcodes
Index()
Two-operand logical operators
Introduction of this change is constrained
to limit incompatibilities with existing ASL
As a best practice, leverage using explicit conversion
functions in your ASL to ensure the type correctness, e.g.
ToBuffer()
ToInteger()
See “Debugging type mismatch warnings”
in the Backup section of this presentation
9. ACPI In Windows Vista
Screen brightness
Laptop LCD brightness controls today are often
implemented with proprietary interfaces
SMM, Embedded Controller firmware
May required 3rd party driver to enable Fn+n hot keys
Breaks on OS upgrade
No in-box support after clean OS install
Not easily debugged
OEM code maintenance burden
Leveraging ACPI makes tight integration
with the operating system easy
Simplifies the implementation
Reduces development and support costs
Enhances reliability
Improves customer experience
10. ACPI In Windows Vista
Screen brightness
Windows Vista supports the ACPI
Appendix B screen brightness objects
_BCL, _BCM
Screen brightness levels are
controlled via Vista power policy
When _BCL, _BCM are present
Separate brightness levels for each
power policy, and for AC and DC
11. ACPI In Windows Vista
Screen brightness
Vista provides a temporary
override to control brightness
Slider control in Windows Mobility Center
WMI interface exposed
to control screen brightness
Get and set the current brightness level
Notification on change events
Allows for custom controls
For details, refer to the white paper
“Integrating with Windows Vista Power Management”
12. ACPI Support In Windows
Machine role flags
Windows Vista leverages the FADT
Preferred_PM_Profile flags
Allows platform firmware to indicate to OSPM
if the system is mobile, desktop, server, etc.
Enables Windows to accurately determine
the default power policy for the system
Previous Windows operating systems
determine a mobile PC based on the
presence of a long-term battery
Vista falls back to this if Preferred_PM_Profile is 0
13. ACPI Support In Windows
Machine role flags
Used throughout Windows Vista to make
mobile versus desktop determination
e.g., disable Hybrid Sleep on mobile PCs
Exposed to application software
through new Win32 API
PowerDeterminePlatformRole()
14. ACPI Support In Windows
Operating system interface
_OSI method can be used to determine
the version of Windows running on the system
Windows Vista string is: “Windows 2006”
OS vendor is the only interface string supported by Windows Vista
Windows will return “true” for all OS interface levels supported
Other _OSI strings
Windows 2000: “Windows 2000”
Windows XP RTM: “Windows 2001”
Windows XP SP1: “Windows 2001 SP1”
Windows XP SP2: “Windows 2001 SP2”
Windows Server 2003: “Windows 2001.1”
Windows Server 2003 SP1: “Windows 2001.1 SP1”
15. ACPI In Windows Vista
Processor power management
ACPI 3.0 domain dependency objects
For multi-processor systems, these
describe any of the relationships between
Physical packages
Physical cores
Logical cores
Describes how OSPM must
coordinate state transitions
Performance states, idle
sleep states, throttle states
16. ACPI In Windows Vista
Processor power management
Methods supported
_PSD (CPU performance state dependency)
_TSD (CPU throttle state dependency)
_CSD (CPU idle state dependency)
C-states on systems with more than one
CPU must be hardware coordinated
_CSD must report CoordType 0xFE HW_ALL
Otherwise, Vista will disable
all C-states deeper than C1
17. ACPI In Windows Vista
Processor power management
New ACPI 3.0 throttling controls
Expand the control interface beyond P_BLK
Allows the use of Functional Fixed Hardware address space
Accommodates processor architecture-specific controls
Allows dynamic throttle states
Objects supported
_PTC
_TSS
_TPC
_TDC
Notify (cpu, 0x82)
18. ACPI Support In Windows
PCI Express
Windows Vista requires _OSC
on PCI Express root bridges
Enables native OS control of PCI Express features
Windows will first evaluate _OSC to query
for supported capabilities
Evaluate _OSC again to assume control
Firmware must grant native OS control of all control field
feature bits, otherwise Windows takes control of none
ASPM
Hot plug
Power Management Event (PME)
Advanced Error Reporting
For details, see
CPA070 “PCI Express In Depth for Windows Vista”
19. ACPI Support In Windows
PCI Express errata flags
Normally, _OSC should control these features
Windows Vista will look for FADT flags to globally
disable some PCI Express features
Message-signaled interrupts
Active State Power Management
These flags are intended as a temporary,
stop-gap mechanism
These features are required per spec
20. ACPI Support In Windows
PCI Express FADT errata flags
However, as PCI Express development
continues, there are a number of systems
that fail to work correctly
This necessitates a platform firmware
override mechanism
The need for these flags will
diminish as PCI Express chipset
development matures
Future versions of Windows may
require these flags to be clear
21. ACPI Support In Windows
PCI Express and legacy GPE
Don’t assert legacy GPE bits when
Windows is granted control of PCI Express PME
Firmware must not assert legacy GPE to notify
OSPM of device wake
Windows is granted control of PCI Express Hot Plug
If system wakes from PCI Express device, set
PCIEXP_WAKE_STS bit in PM1_STS register
Required to accurately notify Windows Vista
of platform wake source
22. ACPI Support In Windows
Reporting wake sources
It is important that platform firmware
correctly reports wake sources
ACPI Fixed Feature hardware
GPE status bits
PCI Express device
Ensure your GPE handler issues
Notify() on appropriate device
Otherwise, Windows may misrepresent
the system wake source
23. ACPI Support In Windows
Reporting wake sources
Windows Vista will log and
display system wake sources
Available in the system event log

Reporting wake sources
Example – system event log wake details
26. ACPI Support In Windows
Reporting wake sources
Carefully handle unattended wake events
When a machine wakes due to an PME# event
or a remote event, BIOS ASL should not issue a
Notify(btn, 0x02) to the fixed feature power
button in order to wake the monitor
This indicates User Present to Windows
The power manager will
Turn on the display
Exit Away Mode, if enabled
Apply the current power policy for system idle timeout
This can break power management scenarios
Consider a Media PC
27. ACPI Support in Windows
ACPI Driver Interface
Currently drivers can call
IOCTL_ACPI_EVAL_METHOD
IOCTL_ACPI_ASYNC_EVAL_METHOD
Requires a handle to device you
want to evaluate method for
No capability to enumerate or evaluate
control methods of child devices
Workarounds often involve redundant
information in namespace
28. ACPI Support in Windows
ACPI Driver Interface
Windows does not allow arbitrary
execution of control methods
Drivers should not evaluate methods
on devices they have no knowledge of
Breaks rules of encapsulation
Leads to system instability
Compromise: Allow control method execution on
child devices beneath the device handle opened
Device should have knowledge of child devices
Allows for cleaner BIOS code in the future
No need to duplicate information in namespace
29. ACPI Support In Windows
ACPI Driver Interface
New IOCTLs to enumerate and evaluate child
device control methods
IOCTL_ACPI_EVAL_METHOD_EX
IOCTL_ACPI_ASYNC_EVAL_METHOD_EX
Take an additional “Name” field
Relative in namespace to the device
you have a handle to
Can be arbitrarily deep
Support passing/returning 64-bit integers
30. ACPI Support In Windows
ACPI Driver Interface
IOCTL_ACPI_ENUM_CHILDREN
Allows enumeration of one level, or multi-level
Supports passing in a filter
Only return specific children
e.g., return only children with _STA method
Returns back an array of child nodes
Flags indicate if a child has descendent
31. ACPI Support In Windows
ECDT Table
ECDT – EC Boot Resource Table
Provides processor-relative resources
of an Embedded Controller
Allows EC op region access before the
entire namespace has been evaluated
Without this table, EC region space is
not available until EC device is enumerated
Verify by providing a _REG method under the EC
Windows Vista will return 2 when _REV is evaluated
Indicates firmware should use ECDT
32. ACPI Test And Debugging
Extracting ACPI tables
The Microsoft ASL compiler supports exporting
ACPI tables and saving them to a disk file
Extracted as ASL
Tables may be modified, temporarily re-loaded on a system
Facilitates development and debugging
Intended only as a firmware development aid – not for deployment!
Usage
asl /tab=DSDT
Produces DSDT.asl
- or –
Asl /=tab*
Produces ACPI.TXT (all tables)
33. ACPI Test And Debugging
Loading ACPI tables
Tables may be loaded from the
registry instead of from BIOS ROM
Requires the checked version of acpi.sys
The table to be overloaded must already
be present in the system's BIOS ROM
For instance, the DSDT can be overloaded
If the machine does not have an SSDT, you cannot force an
SSDT to be loaded from this registry override mechanism
The table with the highest version
number will be loaded
The table loaded into the registry for testing must have a
higher version number than the same table in the BIOS ROM
34. Common ACPI Errors
BIOS using OS memory
Windows Vista validates
ACPI memory type definitions
Microsoft has seen instances
of firmware accessing OS memory
This is a fatal error
Stop 0xA5 (ACPI_BIOS_ERROR)
0x1000
<address>
<length>
Seen when additional memory added to systems
Carefully design for top of memory range
35. Common ACPI Errors
BIOS using OS reclaim memory
Windows Vista validates ACPI memory type definitions
During development, Microsoft discovered instances
of table load from ACPI reclaim memory
ACPI reclaim memory is available for OS
use after ACPI mode has been enabled
Problem is that memory operation region
is mapped as ACPI reclaim
This is incorrect, per the ACPI specification
Load opcode was clarified in ACPI 3.0a
Common error in example code for handling
processor power management capabilities
OEMs and system designers should obtain the latest processor power
management ACPI reference code from your processor vendor
36. Common ACPI Errors
GPE index out of range
Windows Vista validates the index of
general-purpose event bits (GPEs)
GPE indexes referenced must be within
the length of the GPE register blocks
Validation failure results
in a fatal system error
Stop 0xA5 (ACPI_BIOS_ERROR)
Subcode 1 = 0x17 ACPI_INVALID_GPE_INDEX
Subcode 2 = GPE bit index specified
37. Common ACPI Errors
Memory corruption during sleep
During Vista development, BIOS
corruptions of the low 1MB of memory
were observed across suspend/
resume transitions
BIOS developers need to ensure that
their code does not have this issue
Detect this problem with Driver Verifier
38. Common ACPI Errors
Memory corruption during sleep
This check is automatically
enabled on checked builds
System checksums low 1 MB of memory
before, after suspend/resume
Corruption results in stop error 0xC4
DRIVER_VERIFIER_DETECTED_VIOLATION
Subcode 0xB7 indicates the BIOS
has corrupted low physical memory
Parameters 2,3,4: Number of corrupt
pages, first corrupt page, last corrupt page
39. Common ACPI Errors
Update table versions
Be sure to update OEM Revision
field in your table headers
Windows applies BIOS work-arounds
based on this revision
Failure to update this revision may
result in loss of functionality
Example: BIOS known to have problems
with PCI Express ASPM has this feature disabled
Updated ACPI BIOS corrects the problem, but fails
to update OEM Revision in description header
Windows will continue to disable this feature
40. Call To Action
Ensure your systems properly
support ACPI for Windows Vista
Leverage ACPI in place of proprietary
solutions wherever possible
Test your ACPI implementations
using checked builds or with
Driver Verifier enabled
Take advantage of Microsoft’s ASL
compiler and debugger extensions
to facilitate ACPI development

6. _SB.MSV2 is a field unit, which is a part of the field parent
_SB.MSO1
7. From this, we can tell there is something wrong with the object
_SB.MSO1, since it has a 0 offset and a negative length. At this point
we can go back to looking at the ASL to see how it is defined.
