AMD adds RDNA 2 based Van Gogh supporting firmware to Linux
AMD has Added firmware support Converted its codenamed Van Gogh Accelerated Processing Unit (APU) to linux-firmware.git, which is an important Linux repository. Adding firmware support is one of the last steps of hardware enablement in Linux. In many cases, it indicates that the product is about to be released.
AMD (and other hardware vendors) provided new firmware versions for its components in new Linux drivers, and earlier this week AMD released the Radeon Software for Linux 21.30 package. In order to achieve built-in compatibility with new hardware and drivers, the developers of Linux distributions must obtain the firmware separately from linux-firmware.git, which is a general repository of firmware files for various hardware.According to the report, with the release of new driver packages and the upload of firmware, AMD has ensured the basic support of its latest Van Gogh APU in various Linux versions Fronix.
But although AMD’s Van Gogh may be getting closer and closer, we still don’t know anything about this processor.
APU is expected Features Zen 2 core, RDNA 2 based GPU and memory controller Support DDR5 and/or LPDDR5 memory. In architecture, Van Gogh is similar to Microsoft’s custom SoC Xbox X series/S and Sony Game console 5 Console. In addition, the system information report of Valve’s Steam Deck portable console stated that the device has an “AMD VanGogh video card”. As shown in the video from Tested.com.
Officially, the console has a Semi-custom SoC It has four Zen 2 cores running at 2.40 GHz-3.50 GHz and a Radeon GPU based on the RDNA 2 architecture, with 512 stream processors running at 1.0 GHz-3.50 GHz.However, this does not mean that Van Gogh US We are talking about the same Van Gogh that powers Valves’ portable gaming device.
AMD has a The strange way to describe its semi-custom chipIn essence, the semi-custom SoC is a solution based on AMD’s IP block, ALU, FPU, memory controller, interrupt handler, system management controller, and hardware accelerated video encoding/decoding block. These parts are used in the company’s own products, but may be further customized to meet the unique requirements of AMD customers. Since semi-custom chips are a combination of various IP blocks, they can blur the boundaries between established architecture code names.
For this reason, the SoC that powers Valve’s Steam Deck may indeed be a version of AMD Van Gogh. Either It may be composed of the same components as AMD’s Van Gogh, and even looks like this APU to the driver.
It should be noted that the semi-official codename of AMD’s semi-custom SoC does not follow AMD’s own nomenclature. For example, AMD’s APU is named after a famous painter, while Sony’s PlayStation 5’s semi-custom SoC is codenamed Flute.
In other words, either AMD developed an entry-level APU code-named Van Gogh with four Zen 2 cores, plus a fairly high-performance GPU with built-in RDNA 2 drivers, and Valve used it for portable consoles . Or, the APU in Valve’s SteamDeck is a different silicon from AMD’s Van Gogh, but has the same components.
