[PATCH v7 00/10] drm/xe/guc: Improve GuC log dumping and add to devcoredump

[John.C.Harrison]

From: John Harrison <John.C.Harrison@Intel.com>

There is a debug mechanism for dumping the GuC log as an ASCII hex
stream via dmesg. This is extremely useful for situations where it is
not possibe to query the log from debugfs (self tests, bugs that cause
the driver to fail to load, system hangs, etc.). However, dumping via
dmesg is not the most reliable. The dmesg buffer is limited in size,
can be rate limited and a simple hex stream is hard to parse by tools.

So add extra information to the dump to make it more robust and
parsable. This includes adding start and end tags to delimit the dump,
using longer lines to reduce the per line overhead, adding a rolling
count to check for missing lines and interleaved concurrent dumps and
adding other important information such as the GuC version number and
timestamp offset. Also, switch to using the much more compact ASCII85
encoding rather than 0x%08X hexdumping.

There are various internal error states that the CTB code can check
for. These should never happen but when they do (driver bug, firmware
bug or even hardware bug), they can be a nightmare to debug. So add in
a capture of the GuC log and CT state at the point of error and
subsequent dump from a worker thread.

Finally, include the GuC log and full CTBs in a devcoredump capture.

Note that the ultimate aim is to then provide a mechanism for
generating a devcoredump at an arbitrary point (such as dead CTB or
failed selftest) and dumping that to dmesg. There are still a few
issues with doing that, but this is all good steps along the way.

v2: Remove pm get/put as unnecessary (review feedback from Matthew B).
v3: Add firmware filename and 'wanted' version number.
v4: Use DRM level line printer wrapper from Michal W. Add 'dead CTB'
dump support. Lots of restructuring of capture vs dump for both GuC
log and CTB capture for both the dead CTB dump and for future
inclusion in devcoredump.
v5: Add missing kerneldocs and other review feedback from Michal W.
Fix printf of size_t, clean up re-arming of dead CTBs, add GuC log to
devcoredump captures.
v6: Replace hexdumps with much more compact ascii85 encoding, drop
module parameter (review feedback from Matthew B). Fix potential
use-after-free bug.
v7: Couple of bug fixes and a bunch of changes to improve
readability/parsablility of the core dump file, debugfs file and dead
CTB dmesg dump.

[PATCH v7 01/10] drm/xe/guc: Remove spurious line feed in debug print

[John.C.Harrison]

From: John Harrison <John.C.Harrison@Intel.com>

Including line feeds at the start of a debug print messes up the
output when sent to dmesg. The break appears between all the useful
prefix information and the actual string being printed. In this case,
each block of data has a very clear start line and an extra delimeter
is really not necessary. So don't do it.

v2: Fix typo in commit message (review feedback from Michal W.)

[PATCH v7 02/10] drm/xe/devcoredump: Add a section heading for the submission backend

[John.C.Harrison]

From: John Harrison <John.C.Harrison@Intel.com>

The xe_guc_exec_queue_snapshot is not really a GuC internal thing and
is definitely not a GuC CT thing. So give it its own section heading.
The snapshot itself is really a capture of the submission backend's
internal state. Although all it currently prints out is the submission
contexts. So label it as 'Contexts'. If more general state is added
later then it could be change to 'Submission backend' or some such.

[PATCH v7 03/10] drm/xe/devcoredump: Add ASCII85 dump helper function

[John.C.Harrison]

From: John Harrison <John.C.Harrison@Intel.com>

There is a need to include the GuC log and other large binary objects
in core dumps and via dmesg. So add a helper for dumping to a printer
function via conversion to ASCII85 encoding.

Another issue with dumping such a large buffer is that it can be slow,
especially if dumping to dmesg over a serial port. So add a yield to
prevent the 'task has been stuck for 120s' kernel hang check feature
from firing.

v2: Add a prefix to the output string. Fix memory allocation bug.

[PATCH v7 04/10] drm/xe/guc: Copy GuC log prior to dumping

[John.C.Harrison]

From: John Harrison <John.C.Harrison@Intel.com>

Add an extra stage to the GuC log print to copy the log buffer into
regular host memory first, rather than printing the live GPU buffer
object directly. Doing so helps prevent inconsistencies due to the log
being updated as it is being dumped. It also allows the use of the
ASCII85 helper function for printing the log in a more compact form
than a straight hex dump.

v2: Use %zx instead of %lx for size_t prints.
v3: Replace hexdump code with ascii85 call (review feedback from
Matthew B). Move chunking code into next patch as that reduces the
deltas of both.
v4: Add a prefix to the ASCII85 output to aid tool parsing.

[PATCH v7 05/10] drm/xe/guc: Use a two stage dump for GuC logs and add more info

[John.C.Harrison]

From: John Harrison <John.C.Harrison@Intel.com>

Split the GuC log dump into a two stage snapshot and print mechanism.
This allows the log to be captured at the point of an error (which may
be in a restricted context) and then dump it out later (from a regular
context such as a worker function or a sysfs file handler).

Also add a bunch of other useful pieces of information that can help
(or are fundamentally required!) to decode and parse the log.

v2: Add kerneldoc and fix a couple of comment typos - review feedback
from Michal W.
v3: Move chunking code to this patch as it makes the deltas simpler.
Fix a bunch of kerneldoc issues.
v4: Move the CS frequency out of the coredump snapshot function into
the debugfs only code (as that info is already part of the main
devcoredump). Add a header to the debugfs log to match the one in the
devcoredump to aid processing by a unified tool. Add forcewake to the
GuC timestamp read so it actually works.

[PATCH v7 06/10] drm/print: Introduce drm_line_printer

[John.C.Harrison]

From: Michal Wajdeczko <michal.wajdeczko@intel.com>

This drm printer wrapper can be used to increase the robustness of
the captured output generated by any other drm_printer to make sure
we didn't lost any intermediate lines of the output by adding line
numbers to each output line. Helpful for capturing some crash data.

v2: Extended short int counters to full int (JohnH)

[PATCH v7 07/10] drm/xe/guc: Dead CT helper

[John.C.Harrison]

From: John Harrison <John.C.Harrison@Intel.com>

Add a worker function helper for asynchronously dumping state when an
internal/fatal error is detected in CT processing. Being asynchronous
is required to avoid deadlocks and scheduling-while-atomic or
process-stalled-for-too-long issues. Also check for a bunch more error
conditions and improve the handling of some existing checks.

v2: Use compile time CONFIG check for new (but not directly CT_DEAD
related) checks and use unsigned int for a bitmask, rename
CT_DEAD_RESET to CT_DEAD_REARM and add some explaining comments,
rename 'hxg' macro parameter to 'ctb' - review feedback from Michal W.
Drop CT_DEAD_ALIVE as no need for a bitfield define to just set the
entire mask to zero.
v3: Fix kerneldoc
v4: Nullify some floating pointers after free.
v5: Add section headings and device info to make the state dump look
more like a devcoredump to allow parsing by the same tools (eventual
aim is to just call the devcoredump code itself, but that currently
requires an xe_sched_job, which is not available in the CT code).

[PATCH v7 08/10] drm/xe/guc: Dump entire CTB on errors

[John.C.Harrison]

From: John Harrison <John.C.Harrison@Intel.com>

The dump of the CT buffers was only showing the unprocessed data which
is not generally useful for saying why a hang occurred - because it
was probably caused by the commands that were just processed. So save
and dump the entire buffer but in a more compact dump format. Also
zero fill it on allocation to avoid confusion over uninitialised data
in the dump.

v2: Add kerneldoc - review feedback from Michal W.
v3: Fix kerneldoc.
v4: Use ascii85 instead of hexdump (review feedback from Matthew B).
v5: Dump the entire CTB object rather than seperately dumping just the
H2G and G2H sections. That way it includes the full header info.

Signed-off-by: John Harrison <John.C.Harrison@Intel.com>

[PATCH v7 09/10] drm/xe/guc: Add GuC log to devcoredump captures

[John.C.Harrison]

From: John Harrison <John.C.Harrison@Intel.com>

Include the GuC log in devcoredump captures because they can be useful
with debugging certain types of bug.

v2: Fix kerneldoc
v3: Drop module parameter as now using more compact ascii85 encoding
rather than hexdump (although still not compressed) (review feedback
from Matthew B). Rebase onto recent refactoring of devcoredump code.
v4: Don't move the submission snapshot inside the GuC internals
structure 'cos it really doesn't belong there.

[PATCH v7 10/10] drm/xe/guc: Add a helper function for dumping GuC log to dmesg

[John.C.Harrison]

From: John Harrison <John.C.Harrison@Intel.com>

Create a helper function that can be used to dump the GuC log to dmesg
in a manner that is reliable for extraction and decode. The intention
is that calls to this can be added by developers when debugging
specific issues that require a GuC log but do not allow easy capture
of the log - e.g. failures in selftests and failues that lead to
kernel hangs.

Also note that this is really a temporary stop-gap. The aim is to
allow on demand creation and dumping of devcoredump captures (which
includes the GuC log and much more). Currently this is not possible as
much of the devcoredump code requires a 'struct xe_sched_job' and
those are not available at many places that might want to do the dump.

v2: Add kerneldoc - review feedback from Michal W.

why are we not dumping the binary data directly to devcoredump?

As per earlier comments, there is a WiFi driver or some such that does 
exactly that. But all they are dumping is a binary blob.

We want the devcoredump file to still be human readable. That won't be 
the case if you stuff binary data in the middle of it. Most obvious 
problem - the zeros in the data will terminate your text file at that 
point. Potentially bigger problem for end users - random fake ANSI codes 
will destroy your terminal window if you try to cat the file to read it.

In your v5 I see you mentioned
drivers/net/wireless/ath/ath10k/coredump.c, but that is a precedence for
including it as is from the device rather converting it to ASCII85 or
something else. It seems odd to do that type of conversion in kernel
space when it could be perfectly done in userspace.

$ git grep ascii85.h
drivers/gpu/drm/i915/i915_gpu_error.c:#include <linux/ascii85.h>
drivers/gpu/drm/msm/adreno/a6xx_gpu_state.c:#include <linux/ascii85.h>

Users don't get a coredump and cat it to the terminal.

It really can't. An end user could maybe be expected to zip or tar a 
coredump file before attaching it to a bug report but they are certainly 
not going to try to ASCII85 encode random bits of it. Whereas, putting 
that in the kernel means it is just there. It is done. And it is pretty 
trivial - just call a helper function and it does everything for you. 
Also, I very much doubt you can spew raw binary data via dmesg. Even if 
the kernel would print it for you (which I doubt), the user tools like 
syslogd and dmesg itself are going to filter it to make it ASCII safe.

The i915 error dumps have been ASCII85 encoded using the kernel's 
ASCII85 encoding helper function since forever. This patch is just a 
wrapper around the kernel's existing implementation in order to make it 
more compatible with printing to dmesg. This is not creating a new 
precedent. It already exists.

And the list of drivers which dump raw binary data in a coredump file 
is... ath10k. ASCII85 wins 3 to 1.

They might. Either intentionally or accidentally. I've certainly done it 
myself. And people will certainly want to look at it in any random 
choice of text editor, pager, etc. 'cos you know, it is meant to be read 
by humans. If it is full of binary data then that becomes even more 
difficult than simply being full of ASCII gibberish. No matter what you 
are doing, the ASCII version is safer and easier to look at the rest of 
the file around it.

I don't understand why you are so desperate to have raw binary data in 
the middle of a text file. The disadvantages are multiple but the only 
advantage is a slightly smaller file. And the true route to smaller 
files is to add compression like we have in i915.

John.

PS: Also meant to add that one of the important uses cases for dumping 
logs to dmesg is for the really hard to repro bugs that show up in CI 
extremely rarely. We get the driver to dump an error capture to dmesg 
and pull that out from the CI logs. Even if you could get binary data

Since 2 characters are added to the end of prefix should the computation
for n be "DMESG_MAX_LINE_LEN - MIN_SPACE - 2"? MIN_SPACE already
accounts for space of trailing newline and null terminator.

Also, prefix is only added to the first line. Is that the intended behavior?

Since space for ASCII85_BUFSZ bytes is guaranteed by checks against
MIN_SPACE output of strscpy can be used to increment line_pos. Although
I do like this safer style that would work even if the checks failed.

> +#undef MIN_SPACE
Suggest to also #undef DMESG_MAX_LINE_LEN here.

I think that's the main source of confusion on what we are discussing.
I was not talking about dmesg at all. I'm only complaining about feeding
ascii85-encoded data into a *devcoredump* when apparently there isn't a
good reason to do so. I'd rather copy the binary data to the
devcoredump.

For dmesg, there's a reason to encode it as you pointed out... but
no users shouldn't actually see it - we should be getting all of those
cases in CI. For the escape scenarios, yeah... better having it
ascii85-encoded.

What you are adding to devcoredump also doesn't even seem to be an
ascii85 representation, but a multiple lines that should be concatenated
to form the ascii85 representation. For dmesg it makes sense. Not for
devcoredump.  We should also probabaly need a length field (correctly
accounting for the additional characters for each line) so we don't
have an implicit dependency on what's the next field to know how much to
parse.

But the intent is to dump a devcoredump to dmesg. It makes much sense to 
have a single implementation that can be used for multiple purposes. 
Otherwise you are duplicating a lot of code unnecessarily.

And I still think it is a *very* bad idea to be including binary data in 
a text file. The devcoredump is supposed to be human readable. It is 
supposed to be obtained by end users and passed around. Having binary 
data in there just makes everything more complex and error prone. We 
want this to be as simple, easy and safe as possible.

The decoding is pretty trivial given that line feeds are not part of the 
ASCII85 character set and so can just be dropped. Besides The output is 
already not 'pure' ASCII85 because the ASCII85 data is embedded within a 
devcoredump. There is all sorts of other text about, including on the 
start of the line. There are multiple ASCII85 blobs in there that need 
to be decoded separately. This is nothing new to my patch set. All of 
that is already there. And as per comments on the previous devcoredump 
patches from Matthew B, the object data can many hundreds of MBs in 
size. Yet no-one batted an eyelid when that was added. So why the sudden 
paranoia about adding a couple of MB of GuC log in the same form?

And again, arbitrarily long lines (potentially many thousands of 
characters wide) in a text file can cause problems. Having it line 
wrapped gets rid of those potential problems and so is safer. Anything 
that reduces the risk of an error report being broken is a good thing 
IMHO. Robustness is worthwhile!

This needs to be spin_lock_irqsave because CT_DEAD can be called inside 
an ISR. Without the save/restore, it will explicitly enable interrupts 
again and, as seen in the CI failure, that causes a WARNING:
     irq 210 handler dg1_irq_handler+0x0/0x240 [xe] enabled interrupts

It seems err is not yet set in this context. So it would be a random
stack value leaked? Or are there macros setting err I am not aware of here?

Suggest to zero the "int err;" allocation. Or set explicitly.

In general why is xe_gt_err used here over drm_puts? Is it a more
specific error handler in this context?

Missing colon for "GuC version" print format string.

The 'err' inside the xe_gt_err macro is not a local variable from 
outside the macro. It is used to generate the next function call down - 
"drm_err". There is no drm_puts any more because this function is now 
just an allocator, not a printer. So there is no print stream to call 
drm_puts on.

It would only be an issue if the GuC log buffer were over 2GB in size. 
However, the log is limited to 16MB by the GuC interface spec. So there 
is no possibility of 32bit overflow.

Not sure if there is a convention as such, but ~0 seems even less likely 
to be valid than zero. And one has to pick something (or add in the 
extra complication of a 'is_stamp_valid' flag).

Yeah, I think that is left over from when this was adding three extra 
characters rather than just two.

Yes. The first line tells you what the dump is. Then you just have a 
continuous dump with no interrupts other than the line breaks which can 
be fed directly into a decoder.

It seems like an awful idea to dump hundreds of MB to dmesg.  When we
talked about printing to dmesg it was about **GuC log** and on very
initial states of driver probe where we didn't actually have a good
interface for that. And the log wouldn't be so big. If we can already
capture the devcoredump, what would be the reason to dump to dmesg
(other than the non-valid "our CI captures dmesg, and doesn't
capture devcoredump", which should be fixed).

If any sysadmin have their serial console flooded by such garbage there
are 2 reactions: 1) someone got in control of my machine; 2) something
went really bad with this machine. It's not "fear not, wait for it to
complete, it's just normal debug data I will attach to an issue in
gitlab".  And I'm mentioning a serial console here due to that
cond_resched() added, which is only needed because you are trying to do
in kernel space what should be in userspace.

Oh well... looking at this the main reason to use ascii85 I can see is
because we already have parts of *our* devcoredump using it, and
userspace relying on that. That's new to me. Let's stop bringing dmesg
into this discussion.

no, it's not. devcoredump doesn't dictate the format, it's up to the
drivers to do that. See their documentation.

I suppose you are talking about commit 4d5242a003bb ("drm/xe: Implement capture of
HWSP and HWCTX").  Probably because I haven't seen that commit doing an
ascii85 encoding before, otherwise I'd have similar review feedback.

Looking at this just now, so I will also have to balance the previous
users and existing userspace consuming it.

+José, would it be ok from the userspace POV to start adding the \n?
Then we can at least have all fields in our devcoredump to follow the
same format. Are these the decoder parts on the mesa side?

	src/intel/tools/aubinator_error_decode.c
	src/intel/tools/error2hangdump.c?

 From a quick look, read_xe_data_file() already continues the previous
topic when it reads a newline, but the parsers for HWCTX and HWSP
seems to expect to to have the entire topic in a single line. But I may
be missing something.

Sorry I'm not following up this thread.
Add a '\n' where exactly?

You are missing the point.

The construction of a devcoredump file is the best form of crash 
analysis we have. There is no point trying to re-invent that with 
partial versions that only include some of the information in random 
different situations. No matter where the crash has happened or been 
detected, a devcoredump file should be the correct way to debug it. 
Conversely, that means making devcoredump as useful as possible by 
adding in all the important things we might need to debug a problem.

In other words, we want everything in the devcoredump code path and we 
want no other code paths that are duplicated sub-parts of devcoredump.

That is part 1.

As a follow up to that, there is the problem that not all hangs occur at 
points where it is possible to get a devcoredump out via sysfs. Module 
load time, kernel selftests, presi, etc. There are many valid reasons 
why sysfs is not the best answer in all situations. For those 
situations, dmesg is the simplest, most convenient and most reliable 
option. Therefore, we want to be able to send a devcoredump capture to 
dmesg.

That is part 2.

This patch set is addressing part 1 (add the GuC log and other useful 
stuff to devcoredump) and is preparing the way for part 2 (there are 
still problems with not have an xe scheduler job meaning you can't 
actually create a devcoredump in the first place).

I absolutely do not expect to ever dump a devcoredump to dmesg when 
sysfs is available. A sysadmin should never see a devcoredump being 
spewed to dmesg whether large or small. However, there are many reasons 
why developers and/or CI will need that facility. And it is infinitely 
preferable to have that facility available in the driver ready to be 
used than to have to carry a bucket load of patches in private branches.

But *our* devcoredump is supposed to readable by a human. We put lots of 
things in there that developers want to quickly look at to get an idea 
of what happened. So why would we want our driver to dictate a format 
that mixes binary blobs with human readable text? That is the worst of 
all worlds and a right pain for anyone trying to work with a devcoredump 
file - developer or end user.

To break very long ASCII85 streams across multiple lines. That will 
allow the devcoredump file to output via dmesg for the situations where 
reading from sysfs is not possible.

This patch is adding an ASCII85 encoding helper that is more friendly to 
output via dmesg. The patch does not currently change the existing 
ASCII85 encodings of VMs and hw contexts. However, the intention would 
be to update that code to use this helper eventually.

It will break the parser and I don't think we are allowed to break it at this point.

What I can suggest is add another sysfs with a coredump that skips the binary dumps so it is readable by humans.

Do we need to worry about a second dead ct causing conflict with quick
back-to-back CT_DEAD? Suggest to set reported here and to clear it only
from worker thread. Snapshot can be used instead of reported to
determine if it has been printed (in worker_func).

Should the snapshot be taken in the "CT_DEAD_REARM" case?

Does this field need to be cleared or does this accumulate reasons CT died?

Would this guard work against quick back-to-back CT_DEAD calls? This may
not happen? Suggest to move 'ct->dead.reported = true;' into the CT_DEAD
macro. Relates to CT_DEAD macro above.

The intent has always been to add compression as we had in i915. That 
will presumably also break the parser. Although I'm not seeing how a 
debug log parser counts as critical user space that must not ever be broken.

That will just lead to confusion and problems with people sending the 
wrong file. This needs to be kept as simple and error-proof as possible.

No. We are only really interested in the intial cause of a problem. 
Subsequent failures are likely to be caused by the first. So once a 
report has been printed, we just ignore any further failures until a 
reset has happened.

> Should the snapshot be taken in the "CT_DEAD_REARM" case?
No. That is the reset that turns the reporting system back on. I.e. it 
re-arms the reporting trigger.

This is to accumulate in the case of multiple errors in rapid succession 
(i.e. before it has managed to do the dump) to account for the 
possibility that the errors might not be noticed in the order they 
really happened. So it accumulates everything up to the first dump and 
then goes quite.

Not sure what you mean. This whole block is inside an EBUSY error path. 
As part of the retry, it is trying to make space by clearing out G2H 
entries. The ECANCELED error is because a reset or something known 
happened, therefore there is no need to re-report it. If the dequeue was 
successful then it continues with the retry by hitting the "goto try_again".

As above, there is no concern about wanting to do back to back dumps. 
Once a dump has happened, there is no point printing anything further 
until a GT reset has happened. At which point everything is re-enabled.

Again, you should not give an r-b when there are many concerns being

Increment of non-assigned value "g_count". It is static so zero
allocated but suggest to assign to 0 for clarity.

Assigning a static to zero will cause the checkpatch tool to complain 
that you are unnecessarily providing a value that is the default.

In this case of multiple errors accumulated before being printed the
first time (and dead.reported set true) the snapshots would leak when
overwritten. This seems like an issue.

Given the discussion around other parts, it might be prudent to just
upstream this separately via drm-misc.

We shouldn't be breaking the current userspace tools. Any change like this would
need to be synchronized between all the current decode tools.

Perhaps it is time for us to convince devcoredump folks to accept
multiple files like nvme folks were asking a while ago? [1]

Please see other response. Dumping via dmesg is intended for internal 
use and impossible to repro fatal scenarios. There is zero expectation 
and end user would ever see a dump via dmesg. This entire patch set only 
includes one actual trigger for doing such dumps and that is only if 
CONFIG_DRM_XE_DEBUG is defined. Which it would not be for an end user.

And if you are saying that internal developers are not allowed to use 
dumps via dmesg then we might as well give up and go home because there 
are very many bugs for which this is the only viable debug method.

That is why the comment was 'eventually we would like to'. Nothing in 
this patch will break a user tool unless that tool cannot cope with new 
data being added to the core dump. And if we can't add new stuff to core 
dumps then again, we are fundamentally broken.

Is that likely to happen any time soon? That thread was from May 2019. 
We need something now. And it's not clear if that is adding a filing 
system within a single core dump file (i.e. read one file from sysfs and 
then extract later like a tarball) or creating multiple sysfs files that 
all must be read together and passed around together. I would strongly 
advise against the latter. As I said already, the whole coredump thing 
needs to be as simple and easy to use as possible.

If more official support is added to devcoredump itself in some number 
of years time and is actually beneficial, then we can move over to using 
that interface (and break the user land tools again...). But until then, 
this version works with the least amount of disruption for significant 
benefit. I.e., it lets us actually debug problems right now.

For what purpose? Without the rest of this patch set that one patch is 
pointless - it has no other users and it has no other purpose.

I'm just trying to make it easier to upstream this stuff. You'll need to
Cc: it to dri-devel and get acks from drm-misc maintainers anyway to
merge it via drm-xe-next. Or you could just get it merged via
drm-misc-next, in parallel, and just reference this series.

BR,

What I'm saying is, as a user of CONFIG_DRM_XE_DEBUG, I really don't want to see
this big polution in my dmesg everytime.

I understand the case that the machine entirely hang at boot and you have nothing
but the serial log messages that was dumped there. And you want more information
in that view. I understand the case, although I know that we should be really
working to avoid this kind of failure to start with.

A failure on a Firmware communication should never ever caused the platform to hang.
But well, you might tell that in order to solve cases like this you would need
information from why the firmware failed so badly, right?!

This should be a one off case, or a totally separate config, and definitely not
driving decisions of stable api/abi like the devcoredump. Clear now?

How many times have you seen "big polution in your dmesg" so far?

Right now, checked in, as we are currently shipping the Xe driver to the 
public, the spam is far worse than after this patch set. On a CT 
failure, it will dump the the CT buffer contents as a hexdump. If the 
buffer is very backed up (which it often is in the case of a fatal GuC 
failure), that could be something like 2MB of data dumped has a 
one-word-per-line hexdump to dmesg. And that has no config option to 
turn it off at all. I.e., that is enabled and shipping for end users 
with their RedHat default kernel build. This version provides a lot more 
useful information in a much more compact and less spewing form, and is 
off by default. That is, it is producing less "pollution" not more.

Also, this feature has been part of i915 for over a year (or two, or 
three?). How much "big pollution" have you suffered on i915 in all that 
time?

This is not about debugging common hangs caused by end users, bad UMDs, 
etc. This is about debugging fatal kernel or firmware bugs. Those are 
things that should never happen. If you are hitting any of this on a 
regular basis then the driver is fundamentally broken and you can't 
actually be using it for anything meaningful anyway. This is about 
debugging the issues that occur once in a blue moon. And if you ever hit 
one locally (on production hardware, with a production driver and 
production firmware) then I would be incredibly surprised and absolutely 
want to get that log from you to debug what happened.

I have no idea what you mean by "driving decisions of stable api/abi 
like the devcoredump". This is not changing any stable API. It is not 
changing the devcoredump infrastructure. It is adding extremely useful 
features to our private and internally defined coredump content. And if 
you are referring to the dump-via-dmesg (which is config option 
controlled or locally added by a developer themselves), that is not part 
of devcoredump. The intent is to use devcoredump as the container being 
dumped because why duplicate code? Although currently it can't because 
of how we have implemented our devcoredump capture code. But either way, 
it has absolutely zero bearing on any APIs or on how devcoredumps are 
used for regular debugging of end user hangs.

As for config options, sure we can create as many config options as we 
like but this feature absolutely needs to be enabled for CI builds. 
Plus, last time I tried adding a new config option for debug code, I was 
told that we should just use the existing one and not pollute the config 
space.

But like I said, the currently shipping Xe driver has the CT dump 
permanently enabled. There is no config option at all. So using any 
config option is still a significant improvement.
