Damn, another #ram #hack #bug based on #rowhammer #bit #flips named #blacksmith https://comsec.ethz.ch/research/dram/bla.. This is possible in the latest DDR4 RAM and likely DDR5
Nice #discussion about the #implementation of #spinlocks in #gcc and #linux https://blog.regehr.org/archives/2173 I would suggest that the 32 #bit #arm #limit of 65k #cores might *actually* come to bite somebody pretty soon. I could see a stripped down version of Linux running on a GPU in the near future for example.
