Alexandru Duțu has uploaded a new patch set (#18) to the change originally created by Brandon Potter.

The faux-filesystem creates a directory structure in m5out (or whatever output dir the user specifies) where system calls may be redirected. This is useful to avoid non-determinism when reading files with varying path names (e.g., variations from run-to-run if the simulation is scheduled on a cluster where paths may change). Also, this changeset allows circumventing host pseudofiles which have information specific to the host processor (such as cache hierarchy or processor information). Bypassing host pseudofiles can be useful when executing runtimes in the absence of an operating system kernel since runtimes may try to query standard files (i.e. /proc or /sys) which are not relevant to an application executing in syscall emulation mode.

The test contains a "chdir" system call to "/proc" which should be redirected to "$(gem5-dir)/m5out/fs/proc" (as specified by the config files). After "chdir", the test subsequently outputs the "/proc/cpuinfo" file which should output a configuration of a fake cpu with values set by a Python configuration file. Note, the test will call "clone" once. To avoid a runtime error, make sure that you run this test with "-n2" supplied to the "config/example/se.py" script.

Alexandru Duțu has uploaded a new patch set (#9) to the change originally created by Brandon Potter.

It does so because it needs to pass the host fd into the fstat call (since we rely on the host filesystem to service filesystem system calls). The upcast was overly specific. This changeset alters the system call to use the most general base class of the file descriptor entries that can satisfy the code.
