E5-2600 v3 TSX - when will they fix it?

[petreza]

I asked about this in another forum but wanted to check here too to see if anyone knows more.

Intel found a bug in the TSX implementation of their E5-2600 v3 line and disabled it in BIOS.

Here is a quote from the end of this review of the product line:

Transactional Synchronization Extensions (TSX) is an extension to the x86 instruction set architecture that adds hardware transactional memory support, speeding up execution of multi-threaded software through Hardware Lock Elision (HLE). Intel stated that this instruction would not have a big impact on current code, but plans to update silicon in the next processor stepping, but gives no eta on this fix.

Do you think intel will keep their promise to fix TSX with the next stepping?
How long will that be?
How can you find out that the new stepping has been released?

Thanks!

Thanks!
In that link it says:

Those who wish to risk working with TSX in Haswell-EP will have the option to enable it via a firmware menu, but Intel recommends waiting for Haswell-EX before using TSX in production systems.

Could someone that has a system with the new E5-2600 series processors, please confirm that server-grade motherboards, like the Supermico's X10 series, have an option in BIOS to enable TSX (for development purposes), please. I checked the manual for one of them and could not find a reference to TSX.

Thank you!

You'd be best to check with Supermicro support.

I can't say but I have edited BOIS Firmware to extend it to share IRQ's above production means and loaded it to meet my needs where a driver was available - Takes a lot of reading and commitment to do it.

What I find is that your not the only one looking for the path and you may find a lead on a trodden path to no end and in the long run it''s only you walking.

I you ever find it, no one wants it and by then neither do you - Fallibility.
