(Updated août 7, 2016, 4:12 après-midi) Review request for Default. Changes ------- Suppressed useless comment. Summary (updated) ----------------- syscall_emul: Corrected a bug on the syscall "read()" when reading EOF Repository: gem5 Description (updated) ------- syscall_emul: Corrected a bug on the syscall "read()". Read() should not write anything when returning 0 (EOF). This patch does not correct the same bug occuring for : nbr_read=read(file, buf, nbytes) When nbr_read<nbytes, nbytes bytes are copied into the virtual RAM instead of nbr_read. If buf is smaller than nbytes, a page fault occurs, even if buf is in fact bigger than nbr_read. Diffs (updated) ----- src/sim/syscall_emul.cc cdb94f2332a6 Diff: http://reviews.gem5.org/r/3582/diff/ Testing ------- Works with CERE codelets (https://github.com/benchmark-subsetting/cere), correcting the issue when replacing dumps in memory.
