If a reset (GT or engine) happens during EU stall data sampling, all the
EU stall registers can get reset to 0. This will result in EU stall data
buffers' read and write pointer register values to be out of sync with
the cached values. This will result in read() returning invalid data. To
prevent this, check the value of a EU stall base register. If it is zero,
it indicates a reset may have happened that wiped the register to zero.
If this happens, return EBADFD from read() upon which the user space
should close the fd and open a new fd for a new EU stall data
collection session.

As previously discussed, the best way would have been to not have to do
this. We would just plug into the handler for the reset message from GuC,
rather than to implement a reset detection here (and in other places such
as OA). But looks like if we do that, because of the way EUSS registers are
reset, we can return bad EUSS data. So looks like there is no way around
doing this "reset detection" here and a solution with the GuC reset handler
would always be racy. Just for the record.

I don't believe we need to set 'min_data_present = true' if we are setting
'stream->reset_detected = true', correct? See if statement at the bottom.

Also, since the write pointer itself gets reset during reset, didn't we
want to do this register read only when the write pointer is 0 (to avoid an
extra register read every 5 ms)?

The other option is to return -EIO here and implement
DRM_XE_OBSERVATION_IOCTL_STATUS and return status from that. Let me think
some more about this.

So after reset, if a stream is disabled and re-enabled, we expect things to
work again and EUSS data to be correct (without re-opening a new stream)?

Hi Harish,

> return -EBADFD;

Is this making the read() syscall return -EBADFD or setting erno to EBADFD ?  would like to clearly understand how to detect this condition in the UMD. 

Thanks, 
_Matias

Second question: in this condition would require a new return error from the UMD read() API telling the consumer a catastrophic error happened and the streamer must be closed, right ?

I don't believe we need to set 'min_data_present = true' if we are setting 'stream->reset_detected = true', correct? See if statement at the bottom.

Also, since the write pointer itself gets reset during reset, didn't we want to do this register read only when the write pointer is 0 (to avoid an extra register read every 5 ms)?

The other option is to return -EIO here and implement DRM_XE_OBSERVATION_IOCTL_STATUS and return status from that. Let me think some more about this.

So after reset, if a stream is disabled and re-enabled, we expect things to work again and EUSS data to be correct (without re-opening a new stream)?

Thanks for the summary of the previous discussion. Yes, hooking into the
GUc reset notification handler will be racy and bad EUSS data will be
returned to the user space if read() happens after the reset but before
the GuC reset notification message is processed. That's the reason for
not taking that approach.

Agree. The only difference is that the if statement at the bottom will
evaluate true in the current execution of eu_stall_data_buf_poll_work_fn
if min_data_present is set to true. If min_data_present is not set to
true, the if statement will evaluate to true in the subsequent execution
of eu_stall_data_buf_poll_work_fn() which is still okay. So, yes, we
don't have to set min_data_present to true here. Will fix in the next
version.

Good point. I have thought about reducing the number of this register
reads. The poll function reads the write pointers of all the xecores.
A reset can happen anytime the poll function is reading the write
pointers of the xecores. If the reset happens before the poll function
started reading the write pointers, all write pointers are zeros.
If the reset happens during the poll function, several write pointers
read so far can be non-zero while the rest of the pointers after reset
are all zeros. The if reset happens right after the poll function, the
write pointers can be a mix of zeros and non-zeros.
I think the only time this register read can be skipped is if the
LAST write pointer read is non-zero which means a reset did not happen
before or during the poll function. Do you agree? I thought of adding a
check to the if statement to check if the last write pointer is
non-zero, but to keep the code clean, I didn't. Also, if there are
n xecores, there will be n write pointer register reads plus one
additional base register read, which isn't too bad? Also, hoping the use
of unlikely macro would not impact the performance too much.

I think EBADFD is more appropriate errno than EIO in this case since the
fd is in a corrupted state and user has to close and re-open the fd.
Currently, the -EIO is used to indicate drop data in which case, the
user space can continue to read the data (faster) without closing the fd.

Technically, yes, since the EU stall registers programming is done in
enable, things will work again if the stream is disabled and re-enabled.
But if the EUSS registers programming is moved into open() in the
future, things may not work by disabling and re-enabling the stream. So,
I think we suggest to the UMDs to close the stream and open a new
stream.

Thank You

Just switch the order of the two OR operands and you don't have that issue?

OK, leave this as is I think. Otherwise we'll need to read the base
register each time we see a zero write pointer. So it's ok, leave as is.

OK, we can go with -EBADFD, though still thinking about it.

No we don't suggest anything to UMD's. We decide what we want to do,
implement and enforce it that way and then maintain that uapi.

OK, then let us make sure after disable/enable, the reset_detected flag
remains set.

Hi Matias,

On Wed, Mar 18, 2026 at 11:38:29AM -0700, Cabral, Matias A wrote:

Yes the consumer of the UMD read() needs to know that an error has
occurred that requires the streamer be closed. The engine/GT reset must
have happened due to an issue in the profiling application. I think if a
reset happens, the profiling application would quit with an error and
therefore the consumer of the UMD read() would discard any data
collected so far, fix the cause of the reset in the application and
rerun the application and collect the EU stall data again.

Thank You
Harish.

We would just plug into the handler for the reset message from GuC, rather than to implement a reset detection here (and in other places such as OA). But looks like if we do that, because of the way EUSS registers are reset, we can return bad EUSS data. So looks like there is no way around doing this "reset detection" here and a solution with the GuC reset handler would always be racy. Just for the record.

But switching the order of the two OR operands would cause the function
eu_stall_data_buf_poll() to be unnecessarily called even after a reset
is detected.

Okay, I will make sure the reset_detected flag remains set even after a

Hmm, in that case why even keep rescheduling the work? I took a swipe at
doing this a little bit differently and have sent a patch v3. Can you take
a look at that and see what you think. The patch is only compile tested.

I also have a different idea now, which is, should we just call release()
and close the fd in the kernel itself, if reset is detected. Will check
with Umesh about this, I think there was something in perf_pmu which was
doing it. The kernel will automatically return -EBADFD to user land when
user land tries to use the closed fd. I am not sure if we'll eventually do
this, but at least it's good to understand if doing this is feasible.

I think we just need to not to reset it to false here. I took out this line
in v3 I sent.
