The printf used to clear the screen didn't have a format string, this
adds one to avoid a compiler warning.

It can be a bit easier to digest the percentages with bar graphs than by
scanning continually changing numbers.

For a typical vsync locked application running at 60fps, sampling at just
under twice a frame doesn't seem to give very stable lists of relevent hardware
units because there are a number of units involved that may not be sampled one
second to the next.
This bumps the sample rate to 10,000 instead which is ~ 170 samples per
frame so we tend to hit all the units involved.
It also changes the report threshold to a sample count >= 1, so you don't
see as many units with a percentage of 0.

humans are pretty bad at reading percentages quicky; this patch adds a
histogram capability to make it more visually clear as to which lines are
big ticket items

Not that we're really concerned about buffer-overrun attacks
against this utility, but still, good habits and clean code
are always preferred.

This is the case where debugfs is mounted, the dri/0 directory
exists but there's no i915_ringbuffer_info file. Point the user
toward upgrading the driver.

This helps for when the user makes a typo trying to pass a file
or directory name to intel_gpu_dump.
|
|
This is a nice opportunity to teach the user something, (and help our
users to actually succeed in creating useful bug reports for us).

This caught a bug with get_user_pages usage in the kernel, which would
result in zeroes being read out of the object when faulting in a new page.
|
|
Right now it requires a filename on the command line, (such as
/debug/dri/0/i915_batchbuffers). We plan to make it smarter in
the future by going out and collecting all the data it needs.

This comes from the 3D driver within mesa, with identically named files.
In its new life here it will become a standalone program.
