When writing a driver for ARM A64 CPU, we need to write some ASM functions that are then used by C. In this case, we may need to use some general-purpose registers to implement logic functions. So, which general-purpose registers are preferred? anonymous@undisclosed.example.com (Anonymous) Sun, 05 Jan 2025 08:20:12 +0000 https://wiki.pushmindstack.com/arch/arm/a/instruction A64 Instruction Qucik Search Table Instruction Ext Feature Description anonymous@undisclosed.example.com (Anonymous) Sun, 14 Jan 2024 15:28:55 +0000 https://wiki.pushmindstack.com/arch/arm/a/mem_sync_model ARMv8 Synchronization Model ARMv8 designs a synchronization model to provide non-blocking synchronization.
