A walk through setting up Qualcomm compute platforms in order to be able to boot to full Debian via fastboot EFI app chainloaded from grub. All steps starting with setting up the proper rootfs using Linaro provided Debian rootfs images, then repacking the
Optimizing suspend/resume time makes a significant difference for UX
and power savings. Especially for wearable devices which typically
have small CPUs and small batteries. This talk will point out all the
gaps I've found so far and what we could do to
Qualcomm Snapdragon SoCs feature a rich and complex power management
architecture, which maximizes frequency and power control of each
sub-component. Nearly nothing is connected directly to fixed clock or
power sources. This can achieve outstanding per
The Arm64 Linux Kernel is constantly evolving to align with the disruptive Arm architecture enablement story, spanning across 3 spheres : performance, compute and security.
At Arm, we drive this kernel enablement story to facilitate our architecture adop
The FF-A firmware standard (https://developer.arm.com/architectures/Firmware%20Framework%20for%20A-Profile) defines a software ABI that normal and secure world software (as defined in the ARM v8/v9 aarch64 architecture) components can leverage in order to
The kernel currently contains two different ways of generating system call tables across architectures, with bits of it abstracted by rather complicated macros that are universally hated and that that occasionally run into dangerous corner cases when they
TLBI is the TLB invalidation which is needed for updating mappings and attributes of the page table, on ARM the TLBI will broadcast to every CPU core in the inner shareable domain, and we found that TLBI affects the scalability a lot on some workload (suc
BoF aims at providing platform to discuss state of Qualcomm SoCs and Platforms support in Mainline Linux Kernel.
Focusing mainly on.
-> Where we are, Current Status of Qualcomm drivers.
-> Ongoing efforts on new Drivers/Frameworks.
-> Pending problems
With the increasing adoption of SCMI by partners and the extensive enablement
work carried out by Linaro, the SCMI ecosystem can now be deployed in a number
of different configurations across a wide variety of platforms; as a consequence
the approach t
