Perhaps, perhaps not; a hardware design problem that goes back decades just to get performance figures to sell their CPUs is more than bad to say the least - especially when the manufacturers knew about it.
Also, it can't be that hypothetical if it has been proven to work. It is the big/gigantic sytems that will be affected by these patches not so much the piffling little stuff like my MacBook Pro. I can handle a performance hit knowing about it now but can the big guns? <- Rhetorical!
But unless one has experience of writing kernels and OSes then one can't possibly know how difficult it is to create patches, (that will inherently give a performance hit just to _correct_ a deliberate manufacturing fault for profit), that will not slow things down too much.
I read that with the 4.15 Kernel with build-in patches for the hypothetical problem comes with 15-30% performance loss. Immediately I thought 'wow, Intel, AMD and the hardware pushers will earn a lot of $'. I mean todays cpu is so fast that there isn't a need for a upgrade. However the hypothetical problem with the 15-30% performance loss is the need for an upgrade. Again everything comes down to $, and nothing else than $.
Apologies for this newbie question. We have inherited an IBM p5 520 (9111-520) running AIX 22.214.171.124 which seems to be the base install and no further patches installed.
Is this vulnerable to the Spectre/Meltdown threat?
Are patches available?

I had an issue with a second hard disk in my machine. I have a sparc station running solaris 7. It was working fine but now it wont mount on boot up and when you try to mount it manually it gives an I/O error. I tried a different disk as a control which was fine. What I want to know is if my...
