2022-07-25 21:21:00 【DOT小文哥】
在linux bsp中,allwinner平台统一命名为“sunxi”。即:linux bsp中的“sunxi”可以理解为是allwinner的代称。
如linux/arch/arm目录下的machine命名为“mach-sunxi”;
如linux/driver/video目录下显示驱动命名为“sunxi”;
不同系列的芯片平台命名
全志的芯片根据CPU内核的不同,可以分为若干个系列:Cortex-A8单核系列、Cortex-A7 SMP系列、Cortex-A15 HMP系列、Cortex-A53 SMP系列等等。
ARM926单核平台统一命名为“sun3i”。
Cortex-A8单核平台统一命名为“sun4i”。
Cortex-A7 SMP多核平台统一命名为“sun8i”。
Cortex-A15 HMP多核平台统一命名为“sun9i”。
Cortex-A53 SMP多核平台统一命名为“sun50i”。
Cortex-A55 SMP多核平台统一命名为“sun55i”。
注: CPU内核小版本升级,按照小版本升级,在原命名基础上+5,如Cortex-A53 SMP多核平台统一命名为“sun50i”,Cortex-A55 SMP多核平台统一命名为“sun55i”
CPU内核大版本升级,按照大版本升级,在原命名基础上+10,如Cortex-A53 SMP多核平台统一命名为“sun50i”,Cortex-A7X SMP多核平台统一命名为“sun60i”
