Subject: Probing for native availability of isel from userspace
Date: Sat, 22 Sep 2012 00:05:08 +0400 (MSK) [thread overview]
Message-ID: <alpine.LNX.2.00.1209212355050.8539@linmac> (raw)
Hello,
Is it possible to determine if _native_ isel is available from userspace
somehow? So far my searches on the web and within kernel (headers)/glibc
were fruitless (aux vectors, cpu_user_features), few people people (Hollis
Blanchard, Richard Henderson) suggested PPC_FEATURE_ARCH_2_06, but
PowerISA_V2.06B_V2_PUBLIC.pdf says - "3.3.11 Fixed-Point Select [Category:
Phased-In (sV2.06)]" about isel, the sV2.06 (s part) means something i
suppose, furthermore Hollis mentioned that some pre 2.06 cores came with
isel.
Thanks.
