เปิดตัว Linux 6.10 พร้อมเปลี่ยนแปลงที่สำคัญของสถาปัตยกรรม Arm, RISC-V และ MIPS

Linux Torvalds ได้ประกาศเปิดตัว Linux 6.10 บน LKML (Linux kernel mailing list), เมื่อประมาณ 2 เดือนทีผ่านมาได้เปิดตัว Linux 6.9 โดยเพิ่มการรองรับ Intel Flexible Return and Event Delivery (FRED), การรองรับการรัน AMD Secure Nested Paging (SNP) guests, การแก้ไขปัญหา “Register File Data Sampling” (RFDS) ซึ่งเป็นช่องโหว่ทางฮาร์ดแวร์ที่มีผลกระทบกับ Intel Atom CPUs, ฟีเจอร์ named address spaces ของ GCC เพื่อเพิ่มประสิทธิภาพในการเข้าถึงข้อมูล per-CPU, และการรองรับเบื้องต้นสำหรับ FUSE passthrough รวมถึงการเปลี่ยนแปลงอื่น ๆ

Linux 6.10 Release Changelog

การเปลี่ยนแปลงที่สำคัญใน Linux 6.10

การเปลี่ยนแปลงที่สำคัญบางส่วนใน Linux 6.10:

  • การปรับปรุงประสิทธิภาพการทำงานของเครือข่าย – เพิ่มประสิทธิภาพการส่งแบบ zero-copy โดยใช้ io_uring และการรวมหลายบัฟเฟอร์สำหรับการส่งและรับข้อมูล
  • system call mseal() ถูกผสานเข้ากับ Linux 6.10 เพื่ออนุญาตให้กระบวนการห้ามการเปลี่ยนแปลงในส่วนของ address space โดยเฉพาะเบราว์เซอร์ Chrome จะใช้การเรียกใช้ระบบนี้เพื่อเสริมความปลอดภัยภายในของ sandbox
  • Bluetooth เพิ่ม USB HW IDs สำหรับ MT7921/MT7922/MT7925 และรองรับ Intel BlazarI และ Filmore Peak2 (BE201) นี่เป็นสิ่งสำคัญอย่างมากสำหรับผู้ที่ใช้มินิพีซีที่มีโมดูลไร้สาย MediaTek MT7922 เช่นเดียวกับมินิพีซีรุ่นล่าสุด อย่าง GEEKOM A8 ที่ Bluetooth ไม่ทำงานใน Linux จนถึงตอนนี้ การทำงานของ Bluetooth  สามารถทำงานได้กับโมดูล WiFi 7 ของ Intel BE201 อีกด้วย
  • การเปลี่ยนแปลงในระบบไฟล์: เพิ่มโปรโตคอลใหม่สำหรับการควบคุม NFS server ใน kernel, การปรับปรุง XFS filesystem, การรองรับ fs-verity ใน FUSE subsystem และการสร้างไฟล์ชั่วคราวใน overlayfs filesystem โดยใช้ O_TMPFILE

      Until now after a bcm2835 pin was freed its pinmux was set to GPIO_IN. So in case it was configured as GPIO_OUT before the configured output level also get lost. As long as GPIO sysfs was used this wasn’t actually a problem because the pins and their possible output level were kept by sysfs.Since more and more Raspberry Pi users start using libgpiod they are confused about this behavior. So make the pin freeing behavior of GPIO_OUT configurable via module parameter. In case pinctrl-bcm2835.persist_gpio_outputs is set to 1, the output level is kept.

        removed the duplicate firmware-clocks property to bcm2835-rpi.dtsi. Added support for the CAM1 camera interface regulator.
      • Added a pinctrl-based multiplexing description to allow the use of I2C0 pins to allow usage between the 40-pin Raspberry Pi header and the CSI and DSI connectors. Described the PCF85063 RTC device available on the CM4 I/O board making use of that pinctrl-based muxing.
      • Added DT nodes for the CSI Unicam camera interfaces on the Raspberry Pi 4 / BCM2711 SoCs
      • Added support for the Ethernet LEDs on Raspberry Pi 4 B and Raspberry Pi CM4 boards.
    • Arm64 defconfig – build snd_bcm2835 as module
