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 ... WebJul 1, 2015 · # 0x7c03e83b rdhwr $3, $29 ($29=tls)- emulated by kernel normally, for thread support. That one was a bit of a puzzle - this instruction is understood and generated by binutils, but it doesn't actually exist in MIPS. Basically, this loads the thread local storage area pointer into a register, and when the CPU sees it, it generates an illegal ...

WebThe ability to read hardware registers from userland with the RDHWR instruction should depend upon the corresponding bit of the HWREna register being set, otherwise a reserved instruction exception should be generated. However KVM's current emulation ignores the guest's HWREna and always emulates RDHWR instructions even if the guest OS has ...
