Usage: i965_blackbox [OPTION]... [--] COMMAND ARGUMENTS

Run COMMAND with ARGUMENTS where COMMAND is an application using
the i965_batchbuffer_logger_app interface to provide API calling
information to hook into a batchbuffer log.

 -d level  Select batchbuffer decode level, where level is one of
           the following.
             no_decode : do not decode batchbuffer contents
             instruction_decode : only decode the name of each GPU
                                  command
             instruction_details_decode: decode the name and contents
                                         of each GPU command

 -before-ioctl Emit batchbuffer log data BEFORE sending execbuffer2 ioctl
               commands to the kernel

 -send-object-capture For those execbuffer2 ioctl commands with I915_EXEC_BATCH_FIRST
                      set, add an EXEC_OBJECT_CAPTURE exec_object2 whose contents
                      is a string indicating the execbuffer2 ioctl ID

 -emit-total-stats filename Emit -total- counts of GPU commands sent to
                            GPU to named file

 -shader-file  instead of placing the assembly of the shaders directly
               in the log, save the assembly of each shader -binary-
               to a file

 -r level  Select the level to record in the log the relocation data,
           where level is one of the following.
             print_reloc_gem_gpu_updates : log reloc information
             print_reloc_nothing : do not log reloc information

 -pciid pciid Give a hexadecimal value of the PCI ID value for
              the GPU the BatchbufferLogger to decode for; this
              value is used if and only if the driver fails to
              tell the BatchbufferLogger a valid PCI ID value to
              use

 -keep-most-recent N Each execbuffer2 ioctl is given its own file
                          and delete all but the N most recent
                          files while running

 -fileprefix PREFIX Specify the prefix to use for generated files

 -filesize SIZE Specify file size (in bytes) before starting a
                new file at the next execbuffer2 ioctl; ignored
                if -keep-most-recent is active; default value is
                16777216 (which is 16 MB)
 
 -numframes NUM Specify the number of frames before starting a
                new file at the next execbuffer2 ioctl; ignored
                if -keep-most-recent is active default value is
                100

 -gl-lib GL specify the .so from which to load GL/GLX symbols
            (default is libGL.so)

 -gles-lib GLES specify the .so from which to load GLES symbols
                (default is libGLESv2.so)

 -egl-lib EGL specify the .so from which to load EGL symbols
              (default is libGL.so)
