WebFor early MIPS models lacking ll/sc atomics or the rdhwr TLS register, kernel emulation of these features is mandatory; this is standard on Linux. PowerPC (powerpc[-sf], powerpc64[le]) For 32-bit, only big-endian is supported. Hard-float is default but thre is a soft-float option, mainly intended for use with Freescale CPUs that use an ...

WebOct 10, 2024 · In this patch, we use rdhwr to get synci_step. If synci_step is zero, it means that the hardware will maintain the coherence. We need to do nothing. Then for r6+, synci is required to keep icache global. So we can use synci to flush icache. The ISA documents ask a sync and a jr.hb after synci..
