Jakub Kicinski, the maintainer of the network subsystem of the Linux kernel, refused to accept patches from Sergey Semin, explaining his actions by saying that he feels uncomfortable accepting changes from Baikal Electronics employees or for the equipment of this company (the company is under international sanctions). Sergey is advised to refrain from participating in the development of the network subsystem of the Linux kernel until notified. The patches for the STMMAC network driver have implemented support for GMAC and X-GMAC SoC Baikal, and also proposed general fixes to simplify the driver code.
Support for the Russian Baikal-T1 processor and the BE-T1000 system-on-a-chip based on it has been included in the Linux kernel since the 5.8 branch. The Baikal-T1 processor contains two P5600 MIPS 32 r5 superscalar cores operating at 1.2 GHz. The chip contains L2 cache (1 MB), DDR3-1600 ECC memory controller, 1 10Gb Ethernet port, 2 1Gb Ethernet ports, PCIe Gen.3 x4 controller, 2 SATA 3.0 ports, USB 2.0, GPIO, UART, SPI, I2C. The processor provides hardware support for virtualization, SIMD instructions, and an integrated hardware accelerator of cryptographic operations that supports GOST 28147-89. The chip was developed using a MIPS32 P5600 Warrior processor core block licensed from Imagination Technologies.
