Hello, "perf top --stdio" (or perf kvm top --stdio) keyboard handling does not work properly for me. Instead of accepting key presses, it just displays the "Mapped keys:" help output always.
Seems to be related to this glibc 2.28 stdio change: https://sourceware.org/git/?p=glibc.git;a=blob;f=NEWS * All stdio functions now treat end-of-file as a sticky condition. If you read from a file until EOF, and then the file is enlarged by another process, you must call clearerr or another function with the same effect (e.g. fseek, rewind) before you can read the additional data. This corrects a longstanding C99 conformance bug. It is most likely to affect programs that use stdio to read interactive input from a terminal. (Bug #1190.) Also "perf top </dev/null" with or without --stdio does not behave very well either... -Tommi
