somlogeertu: trying to figure out the difference between when `pahole` tells me useful things about driver data structure layout (i.e., when I compile a litex-rocket 64-bit kernel) and when it gives up and says "file <foo.o> has no supported type information" (like when I compile a 32-bit vexriscv kernel, or a 64-bit intel one)19:59
somloam I missing some kernel CONFIG setting that enables some sort of additional debugging symbols being added to the driver .o files?19:59
somlosame for a 32-bit intel kernel :(20:01
somlofunny/weird thing is, I have absolutely no earthly idea why it actually works on my 64-bit risc-v kernel :)20:02

amstananyone have an arty a7? what does the linux support look like for the ARM core? I would really like to play with litex and perhaps make linux drivers for more of the litex ip blocks21:50
amstani considered the de10 nano, but it's out of stock21:51
bjonnhI have an arty z721:51
bjonnhbut it is painful to not have the uart on the fpga21:51
