Ubuntu akan mendukung SpacemiT K3 sebagai SoC RISC-V RVA23 awal

Canonical mengumumkan bahwa Ubuntu 26.04 LTS akan mendukung SpacemiT K3, salah satu prosesor RISC-V pertama yang sesuai spesifikasi RVA23. Chip delapan inti ini mencakup fitur canggih seperti pemrosesan vektor dan akselerator AI, menandai kemajuan bagi Linux pada perangkat keras RISC-V. Papan pengembangan dari Banana Pi dan Milk-V sudah tersedia untuk pengujian.

SpacemiT K3 merupakan kemajuan signifikan dalam teknologi RISC-V, menyediakan salah satu prosesor pertama dengan fitur RVA23, termasuk unit pemrosesan vektor dan fungsi virtualisasi yang diperlukan distribusi Linux terbaru seperti Ubuntu 25.10. SpacemiT mengumumkan inti CPU X100 yang kompatibel RVA23 pada awal 2025, awalnya untuk VitalStone V100 64-inti yang lebih kuat. Kini, perusahaan menyediakan sampel pertama K3 delapan inti, yang berkecepatan hingga 2,4 GHz. Setiap inti memiliki 64 KB cache L1 untuk instruksi dan data, dengan total 8 MB cache L2 yang dibagi dalam segmen 4 MB di antara kelompok empat inti. TDP chip berkisar 15 hingga 25 watt, memerlukan pendingin kipas. Komponen terintegrasi mencakup akselerator AI dengan delapan unit A100 hingga 60 TOPS, dan inti grafis 3D dari Imagination Technology IMG BXM-4-64-MC1, mendukung OpenGL ES, Vulkan, dan OpenCL. Opsi I/O meliputi delapan jalur PCIe 3.0, USB 3.0, Ethernet 1 Gbit/s, eMMC 5.1, UFS 2.2, SDIO, I2C, SPI, I2S, dan hingga 132 GPIO. Pengontrol memori mendukung dua saluran 32-bit LPDDR4X-4266 atau LPDDR5-6400, memungkinkan bandwidth hingga 51 GByte/s dan maksimal 32 GB RAM. Blog Canonical mengonfirmasi bahwa Ubuntu 26.04 LTS, kode Resolute Raccoon yang dijadwalkan April 2026, akan berjalan di K3. Sementara itu, Ubuntu 24.04 LTS terus mendukung SpacemiT K1 sebelumnya, digunakan di papan seperti Orange Pi RV2 (Ky K1) dan Banana Pi BPI-F3. SpacemiT membandingkan inti X100 K3 dengan ARM Cortex-A76 2018 di Broadcom BCM2712 Raspberry Pi 5. Pengembangan difasilitasi oleh modul inti K3 CoM260, tersedia dengan 8, 16, atau 32 GB RAM LPDDR5-6400. Papan pembawa termasuk BPI-SM10 Banana Pi, dengan dua slot M.2, empat port USB-A 3.0, DisplayPort 1.2, Gigabit Ethernet, dan USB-C. Jupiter 2 Milk-V menawarkan antarmuka serupa. Kit Dev Jupiter 2 dengan 8 GB RAM dihargai 251 Euro tapi habis stok via Arace di Hong Kong. K3 menjanjikan performa layak tapi lebih mahal dari Raspberry Pi 5.

Linus Torvalds announced the stable release of Linux kernel 6.19 on February 9, 2026, following an eight-week development cycle with a one-week delay. Marking the end of the 6.x series—like 3.x to 4.0 and 5.x to 6.0—this non-LTS version (6.18 LTS until December 2027) brings extensive enhancements for Intel/AMD/Arm hardware, older GPUs, file systems, peripherals, HDR graphics, networking, virtualization, and cloud environments. Torvalds timed it with a major U.S. sporting event, joking, "6.19 is out as expected -- just as the US prepares to come to a complete standstill later today, watching the latest batch of televised commercials," and noted the next kernel will be 7.0 as he's "running out of fingers and toes."

The upcoming Linux 7.0 kernel will introduce mainline support for the SpacemiT K3 RVA23 system-on-chip and the Qualcomm Kaanapali. This development aims to enhance compatibility for these processors within the open-source ecosystem. Phoronix reports on these hardware advancements in the Linux kernel.

Canonical has announced that 2026 will mark the mainstream adoption of Ubuntu Linux on RISC-V processors for desktops, servers, and other devices. The company anticipates a shift from experimental trials to widespread commercial products. This follows preparations in 2025 focused on readiness for the open-source architecture.

Independent Linux benchmarks reveal that China's Loongson 3B6000 12-core processor significantly underperforms compared to AMD's Ryzen 5 9600X, highlighting ongoing challenges in domestic chip development. The tests, conducted on a basic evaluation board, underscore the impact of the Loongson's lower clock speeds. Despite advances in multi-core design, the chip remains far from matching mainstream Western processors.
