To: igt-dev
Fix these multiple issues to get basic functionality up
and running on GuC using:
1. Start using the updated debugfs path for all GuC relay-logging
file names.
2. Use the updated debugfs names for the relay-logging control
and channel files to match kernel changes.
3. Start querrying the relay sub-buffer info (buffer size and
number of sub-buffers) from kernel's new debugfs files.
4. Separate the control enabling from the log-level-setting and
keep the control handle open while collecting the logs.

val could only be 0 or 1 in this function now, no uint64 needed, it
could be something like:
str = val? "0x1" : "0x0";
No string alloc/free needed.

alan: actually in coming patches more we end up with 3 options "0x1", "0x2" or "0x3".
instead, i could add a local array of 'const char * array_strings = { "0x1", "0x2", "0x3" };'
and use string 'array_strings[val-1]' (after verifying val)?
since its a known short list, we dont need to use the asprintf

Refactor all of the global variables used in intel_guc_logger
into abstractions of structures at thread level, GuC-GT level
and global level.
While at it, remove asserts from the non primary thread to ensure
process cleanup doesn't get stuck.

alan:sure will change to "int" like patch #1 direction and change the enum names to #defines.
side note: above code will look different, not using asprintf, not needing typecase after i fix
it as per your review comment of patch 1 anyway. I will change to int anyway.

alan: yeah thanks - this series last rev was published sometime back - but i will fix this
on the next patch that properly handles multi-gt platforms - for this patch #2, I'll
keept defaulting to single-gt product only as above. the next patch needs to be fixed for that.

With the introduction of MTL and multi-tile products, add a new
cmd line param for users to select which GT to collect GuC relay
logs from.

Add an abstraction for the flusher-thread's code that writes
the log buffer data to file. This prepares us for future
patches that requires calling the same helper for different
types of data flushing.

We need to redesign the logger to generate an output file that's formatted
as a single log buffer. It needs to continuously concatenate new GuC Log
buffer samnples provided by the kernel. To do this, the logger needs the
header structure of GuC log buffers as per the definition of the GuC
firmware.
Add this header structure that will be used in upcoming patches to extract
GuC Log debug entries.

On the first log sample flushed from kernel, copy the GuC Log-events
header structure once at start of file.
With every new subbuffer flush, use the latest header's head and
tail pointers to extract only new valid data. Concatenate this
new set of debug logs into the output file.
Ensure the logger reorders content when dealing with wraparound of
the read and write pointers received log samples.
When ending, before closing the output file handle, go back to the
single header struct at start of file and update the read, write and
size offsets to make the valid buffer range take up the entire
output file contents.

Update header structure definition and make logger
aware of the fw overflow flag so that it can warn the
end user of possible decode issue at that point in the
file. Also, copy the entire buffer irrespective of the
head and tail ptrs when overflow occurs.

Because the GuC Log buffer header structure has a buffer-size
data type of 32 bits, let's make the output file size limit
a total of 4GB.

By default, don't change the verbosity if the user hasn't explicitly
requested to change it. Also, don't allow users to set the GuC log
verbosity to level of 0 (i.e. disabled) else the logger will not
receive any data.
Also, fix a bug where we set the verbosity at the end of logging
to zero. Instead, save the original GuC log verbosity when we start
the logger and then restore that value.

On exit, trigger the kernel, via debugfs, to flush any leftover GuC
log data so we can receive and save that into the end of the
output file using existing helper function.
