The Linux Block Layer - Built for Fast StorageKernel TLV
The arrival of flash storage introduced a radical change in performance profiles of direct attached devices. At the time, it was obvious that Linux I/O stack needed to be redesigned in order to support devices capable of millions of IOPs, and with extremely low latency.
In this talk we revisit the changes the Linux block layer in the
last decade or so, that made it what it is today - a performant, scalable, robust and NUMA-aware subsystem. In addition, we cover the new NVMe over Fabrics support in Linux.

Kernel Recipes 2015: Representing device-tree peripherals in ACPIAnne Nicolas
Platforms using ACPI firmware are becoming increasingly interesting to embedded developers. This presentation will demonstrate the new features in the ACPI 5.1 specification which make it possible for ACPI to transparently represent devices using existing device-tree bindings, and for Linux to use existing device drivers which should automatically work for both ACPI and device-tree.

HKG18-402 - Build secure key management services in OP-TEELinaro
Session ID: HKG18-402
Session Name: HKG18-402 - Build secure key management services in OP-TEE
Speaker: Etienne Carriere
Track: Security
★ Session Summary ★
The session presents an initiative to build secure key management services in the OP-TEE project. Based on OP-TEE services (persistent storage, cryptography, time, etc) one could build a trusted application of store and use secure keys. An open source implementation for generic key services could be of interest. However there are many client APIs defined in the ecosystem which is a matter of concern for standardization of such services. The session will open a discussion on this and presents the current choice of the PKCS#11 Cryptoki. There can be lot of key attributes and cryptographic schemes to be supported. The session will present the current plans (starting from AES flavors) and what is currently missing in the OP-TEE (as certificate support, bootloader support). This session aims at getting feedback from the community on this topic, discuss about expected services and client APIs.

Launch the First Process in Linux SystemJian-Hong Pan
The session: https://coscup.org/2022/en/session/AGCMDJ
After Linux kernel boots, it will try to launch first process “init” in User Space. Then, the system begins the featured journey of the Linux distribution.
This sharing takes Busybox as the example and shows that how does Linux kernel find the “init” which directs to the Busybox. And, what will Busybox do and how to get the console. Try to make it like a simple Linux system.
Before Linux kernel launches “init” process, the file system and storage corresponding drivers/modules must be loaded to find the “init”. Besides, to mount the root file system correctly, the kernel boot command must include the root device and file system format parameters.
On the other hand, the Busybox directed from “init” is a lightweight program, but has rich functions, just like a Swiss Army Knife. So, it is usually used on the simple environment, like embedded Linux system.
This sharing will have a demo on a virtual machine first, then on the Raspberry Pi.

Föreställ dig en tegel och motor butik där entrén är delvis blockerad, produkter dåligt organiserade, utan ordentliga skyltar. Skulle detta vara en kundvänlig butik att handla i? Skulle det ge kunderna en bra upplevelse? Kommer det göra att kunden kommer tillbaka igen? Skulle inte tro det.

2. Назначение материнской
платы
Материнская плата - плата, на
которой содержатся основные
компоненты компьютера,
обеспечивающие логику работы.
На системной плате монтируется
чипсет, это микросхемы, которые
обеспечивают и контролируют логику
функционирования платы, на плате
также располагаются разъемы для
подключения центрального
процессора, графической платы,
звуковой платы, жесткий дисков,
оперативной памяти и другие
разъемы.
4. Гнездо
один из процессоров,
присоединяется к материнской
плате и быстрее охлаждает
компьютер.
5. Флоппи Диск
портативный носитель информации, используемый
для многократной записи и хранения данных,
представляет собой помещен в защитный
пластиковый корпус гибкий магнитный диск,
покрытый ферромагнитным слоем.
6. SATA
служит для подключения накопителей
информации (жестких дисков, оптических
приводов)
7. PCI
системная шина для подключения
периферийных устройств к материнской
плате компьютера.
8. Южный мост
Передача данных между портами USB,
оптическими приводами и жестким диском.
Кроме того, он отвечает за устройства ввода:
клавиатура, мышь.
9. Северный мост
Одна из составляющих чипсета, которая влияет
на производительность компьютера. Северный
мост определяет частоту системной шины,
возможный тип оперативной памяти, ее
максимальный объем и скорость обмена
информацией с процессором.
10. Слоты ОЗУ
Оперативная память.
Передает процессору
данные непосредственно или
через кэш-память.
11. ATX
Разъемы для подключения блока питания.
Основной разъем, питающий все компоненты
(ATX) имеет 24 контакты
13. Разъем звуковой карты
устройство, позволяющее работать со звуком
на компьютере (выводить на акустические
системы и записывать в компьютер).
14. RJ-45
физический интерфейс,
который в целом
используется для
соединения
компьютерных сетей с
помощью свитой пары
через сетевой
коммутатор, или при
создании сети из двух
компьютеров к друг другу
через сетевую карту.
