# Apache manifest example
#
# This manifest was prepared and tested on Ubuntu 16.04.
#
# Apache must be run with the pal_loader:
#
# ./pal_loader httpd.manifest <script>

# The executable to load in Graphene.
loader.exec = file:$(INSTALL_DIR)/bin/httpd
loader.execname = httpd

# Graphene environment, including the path to the library OS and the debug
# option (inline/none).

# Mounted FSes. The following "chroot" FSes mount a part of the host FS into the
# guest. Other parts of the host FS will not be available in the guest.

# Default glibc files, mounted from the Runtime directory in GRAPHENEDIR.

# SGX general options

# Set the virtual memory size of the SGX enclave. For SGX v1, the enclave
# size must be specified during signing. If Apache needs more virtual memory
# than the enclave size, Graphene will not be able to allocate it.
sgx.enclave_size = 512M

# Set the maximum number of enclave threads. For SGX v1, the number of enclave
# TCSes must be specified during signing, so the application cannot use more
# threads than the number of TCSes. Note that Graphene also creates an internal
# thread for handling inter-process communication (IPC), and potentially another
# thread for asynchronous events. Therefore, the actual number of threads that
# the application can create is (sgx.thread_num - 2).
#
# We (somewhat arbitrarily) specify 32 threads since mpm_worker_module can create
# up to 25 threads/process.
