Dear all,
As I have written in another thread, I need to run an image processing
application in full system mode using caches and O3 CPU. The ISA is X86.
The application creates a JPEG image as its output, which I need to find on
the disk image after the simulation is terminated.
For this purpose, I have turned off the COW layer in FSConfig.py. as it
follows:
class RawIdeDisk(IdeDisk):
image = RawDiskImage(read_only=False)
def childImage(self, ci):
self.image.image_file=ci
#class CowIdeDisk(IdeDisk):
# image = CowDiskImage(child=RawDiskImage(read_only=True),
# read_only=False)
# def childImage(self, ci):
# self.image.child.image_file = ci
And inside def makeX86System:
# disk0 = CowIdeDisk(driveID='master')
# disk2 = CowIdeDisk(driveID='master')
disk0 = RawIdeDisk(driveID='master')
disk2 = RawIdeDisk(driveID='master')
I disregarded the options such as --caches and --cpu-type and tried running
the simulation, and I observed that the output JPEG image is stored on the
disk image only when I don't use the --script option and execute the
commands of the script (called cjpeg.rcS) in an attached terminal instead.
Otherwise, when I use the option --script=configs/boot/cjpeg.rcS, the
created JPEG image is not stored on the disk image.
My question is how I can have the JPEG image stored on the disk image in
the latter case too.
I would appreciate any help or idea.
Azadeh
