Question meltdown proof of concept (official) - does it work?


Here is the official proof of concept (pof) code, for meltdown as linked from the official page.

In my testing the testing fails. Kernel 4.4.xx.

If you have kernel earlier tha 4.12 those are some testing commands
Code:
taskset 0x1 ./reliability # <- in my case 0% success
and
Code:
./memory_filler 9 # <-- 9 = 9GiB! Be carefull, not more that your free memory, or the machine will be very slow.
#in another terminal as root.
taskset 0x1 ./memdump
Does it work on your cpu?

I just found a similar thread.

I have better success (some random characters, not the text in question) only once and with this flag because I have old processor.
Code:
make clean; CFLAGS='-DNORDTSCP' make
I also have 32-bit processor and it does not compiles.
