[PATCH v8 0/7] Add support for EU stall sampling

[Harish Chegondi]

The following patch series add support for EU stall sampling,
a new hardware feature first added in PVC and is being supported
in XE2 and later architecture GPUs. This feature would enable
capturing of EU stall data which include the IP address of the
instruction stalled and various stall reason counts.

Support for this feature is being added into Mesa:
https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/30142

New IGT tests for EU stall sampling are being added:
https://patchwork.freedesktop.org/series/143030/

This patch series has undergone basic testing with the new IGT tests.

Thank You.

[PATCH v8 1/7] drm/xe/topology: Add a function to find the index of the last enabled DSS in a mask

[Harish Chegondi]

Last enabled DSS in a DSS mask can help estimate the maximum DSSes enabled
in the DSS mask, as the enabled DSSes can be discontiguous.

[PATCH v8 2/7] drm/xe/uapi: Introduce API for EU stall sampling

[Harish Chegondi]

A new hardware feature first introduced in PVC gives capability to
periodically sample EU stall state and record counts for different stall
reasons, on a per IP basis, aggregate across all EUs in a subslice and
record the samples in a buffer in each subslice. Eventually, the aggregated
data is written out to a buffer in the memory. This feature is also
supported in XE2 and later architecture GPUs.

Use an existing IOCTL - DRM_IOCTL_XE_OBSERVATION as the interface into the
driver from the user space to do initial setup and obtain a file descriptor
for the EU stall data stream.  Input parameter to the IOCTL is a struct
drm_xe_observation_param in which observation_type should be set to
DRM_XE_OBSERVATION_TYPE_EU_STALL, observation_op should be
DRM_XE_OBSERVATION_OP_STREAM_OPEN and param should point to a chain of
drm_xe_ext_set_property structures in which each structure has a pair of
property and value. The EU stall sampling input properties are defined in
drm_xe_eu_stall_property_id enum.

With the file descriptor obtained from DRM_IOCTL_XE_OBSERVATION, user space
can enable and disable EU stall sampling with the IOCTLs:
DRM_XE_OBSERVATION_IOCTL_ENABLE and DRM_XE_OBSERVATION_IOCTL_DISABLE.
User space can also call poll() to check for availability of data in the
buffer. The data can be read with read(). Finally, the file descriptor
can be closed with close().

v8: Used div_u64 instead of / to fix 32-bit build issue.
    Changed copyright year in xe_eu_stall.c/h to 2025.
v7: Renamed input property DRM_XE_EU_STALL_PROP_EVENT_REPORT_COUNT
    to DRM_XE_EU_STALL_PROP_WAIT_NUM_REPORTS to be consistent with
    OA. Renamed the corresponding internal variables.
    Fixed some commit messages based on review feedback.
v6: Change the input sampling rate to GPU cycles instead of
    GPU cycles multiplier.

[PATCH v8 3/7] drm/xe/eustall: Implement EU stall sampling APIs for Xe_HPC

[Harish Chegondi]

Implement EU stall sampling APIs introduced in the previous patch for
Xe_HPC (PVC). Add register definitions and the code that accesses these
registers to the APIs.

Add initialization and clean up functions and their implementations,
EU stall enable and disable functions, poll() and read() implementations.

A timer thread periodically polls the EU stall data buffer write pointer
registers to look for any new data and caches the write pointer. The read
function compares the cached read and write pointers and copies any new
data to the user space.

v8: Updated copyright year in xe_eu_stall_regs.h to 2025.
    Renamed struct drm_xe_eu_stall_data_pvc to struct xe_eu_stall_data_pvc
    since it is a local structure.
v6: Fix buffer wrap around over write bug (Matt Olson)

[PATCH v8 4/7] drm/xe/eustall: Return -EIO error from read() if HW drops data

[Harish Chegondi]

If the user space doesn't read the EU stall data fast enough,
it is possible that the EU stall data buffer can get filled,
and if the hardware wants to write more data, it simply drops
data due to unavailable buffer space. In that case, hardware
sets a bit in a register. If the driver detects data drop,
the driver read() returns -EIO error to let the user space
know that HW has dropped data. The -EIO error is returned
even if there is EU stall data in the buffer. A subsequent
read by the user space returns the remaining EU stall data.

[PATCH v8 5/7] drm/xe/eustall: Add EU stall sampling support for Xe2

[Harish Chegondi]

Add EU stall sampling support for Xe2 architecture GPUs - LNL and BMG.
EU stall data format for LNL and BMG is different from that of PVC.

v8: Renamed struct drm_xe_eu_stall_data_xe2 to struct xe_eu_stall_data_xe2
    since it is a local structure.

[PATCH v8 6/7] drm/xe/uapi: Add a device query to get EU stall sampling information

[Harish Chegondi]

User space can get the EU stall data record size, EU stall capabilities,
EU stall sampling rates, and per XeCore buffer size with query IOCTL
DRM_IOCTL_XE_DEVICE_QUERY with .query set to DRM_XE_DEVICE_QUERY_EU_STALL.
A struct drm_xe_query_eu_stall will be returned to the user space along
with an array of supported sampling rates sorted in the fastest sampling
rate first order. sampling_rates in struct drm_xe_query_eu_stall will
point to the array of sampling rates.

Any capabilities in EU stall sampling as of this patch are considered
as base capabilities. New capability bits will be added for any new
functionality added later.

v7: Change sampling_rates from a pointer to flexible array.
v6: Include EU stall sampling rates information and
    per XeCore buffer size in the query information.

Subject: [PATCH v8 0/7] Add support for EU stall sampling

The following patch series add support for EU stall sampling, a new hardware feature first added in PVC and is being supported in XE2 and later architecture GPUs. This feature would enable capturing of EU stall data which include the IP address of the instruction stalled and various stall reason counts.

Support for this feature is being added into Mesa:
https://gitlab.freedesktop.org/mesa/mesa/-/merge_requests/30142

New IGT tests for EU stall sampling are being added:
https://patchwork.freedesktop.org/series/143030/

This patch series has undergone basic testing with the new IGT tests.

Thank You.

Our profiler, iaprof, also consumes EU stalls using this patch series and
generates AI flamegraphs using them. I've been testing mostly with v7 of this
patch series since it came out, and have had no issues with it. The stalls are
reasonable (both the reasons and the GPU address that they point to), and we've
been able to poll them well enough to run our profiler in the background.

I suspect the following was already discussed for one of the earlier versions of
this series, but is it possible to have even lower sampling rates than what are
currently provided? We're already selecting the slowest sampling rate (the last
in the array), but CPU usage is too high for our liking, and we're still getting
tens of millions of samples per minute.

Someone else should still probably check if the term "xecore" in
"per_xecore_buf_size" is appropriate. I don't know if it is, or if it is
future proof, as I had remarked earlier.

I think we should move this reserved array before num_sampling_rates. If
later we take up a reserved u64 (replace it by a different struct member)
we'd want num_sampling_rates and sampling_rates[] together.

The Mesa PR still seems to have some data structs from an older version,
but after addressing the above comments, the uapi introduced in this series
is LGTM, so for the uapi:

The convention here seems to be to keep function definitions in .c and

Can't we just add the final function to this patch?

What is the purpose of providing documenatation for static functions, such
as the functions above? There is no useful information in such
documentation at all.

Let's save some lines of code and vertical real estate and provide
documenation only for functions which are exposed in a .h. Unless there is
a "real" reason for providing documentation for something.

Not sure why you've introduced these empty functions in this patch, they
should just be introduced in later patches where they have valid bodies.

The idea is that the initial patches should just add lines of code, not
remove lines of code. If you see the initial OA patches, there is not even
a single line of deleted code:

	git log --stat 67977882a2f1..392bf22238ff

Don't worry about adding a few lines of code to the later patches.

Anyway I don't want you to spend too much time changing patches again, so
I'm ok leaving things as is too. Just let me know if it's going to be a
problem and what you prefer. I am just letting you know what the preferred
practice is.

on it meanwhile. I will pick up reviewing it again next week.

Once again, overall advice for the patch: think carefully if a static
function needs documentation. And if it needs documentation, does it need
each parameter described, even if that conveys 0 information. My
recommendation is to only include documentation for functions called by
other files (function exported via the .h). At least let's not follow a
rule where every function has a header.

This is towards kernel recommendation of minimizing documentation and
having self-documenting code.

This patch is also a little bit too big. I think at least it can be split
into two: the read and the initialization parts can be separated
out. Anyway for now I will plod on with this review.

What is the purpose of including these data structs in the code? Afaict
they are not used anywhere, except for sizeof()? You might as well as just
store the sizeof in a table?

Don't use unnecessary variables, just use xe->info.platform.

Don't initialize I think, add an else with xe_gt_WARN_ON, if that works.

Use GRAPHICS_VERx100 or GRAPHICS_VER, so that later you can just say 'if
(GRAPHICS_VER(xe) >= 20)' to avoid changing code for each platform.

PVC is GRAPHICS_VERx100(xe) 1260, though just for PVC you can use
xe->info.platform.

As I mentioned in the other patch, we need to see why is so much code
moving around? Generally we should not have to delete lines of code in
these patches.

During EU stall sampling, a timer thread in the driver keeps polling for
new EU stall data approximately once every 10 milliseconds. I am wondering if this
could be contributing to the CPU usage too.

Had a chat with Matt Roper offline regarding this. He said XeCore is a
formal name in the hardware for a GPU core. So I think this is
appropriate.

I noticed that in structures with reserved fields, the reserved
fields are at the bottom of the structure. Although flexible array 
sampling_rates is at the bottom, no storage is allocated for
sampling_rates. I can move the reserved array, but is it okay for
reserved array to not be at the end of the structure? Even if I move,
the num_sampling_rates and sampling_rates[] will be next to each other,
but no storage will be allocated to sampling_rates.

Yes let's move it before num_sampling_rates. Look at 'struct

Yes, usually. But if it is a single liner, it is okay to put it in the
header file as a static inline as per the review feedback in V4:

I am able to compile this patch without any errors. Which config file
are you using? Earlier there was a 32-bit build error due to 64-bit

As per the https://docs.kernel.org/doc-guide/kernel-doc.html ,
while the documentation is not required for static functions,
it is recommended for consistency.

From a review feedback in series V3:

   Initial patch that implements the basic interface
   and such, but just stubs out the parts that actually go touch
   hardware.

Since I didn't have any code in this patch that touches the hardware,
some functions are empty.

I have moved some code around into different functions in the next
patch. There isn't much code that is deleted. Will try to improve it in
the next patch series.

I get this:

Not sure if this comes from 'CONFIG_UAPI_HEADER_TEST=y'.

In .c files inline should not be used, the decision whether to inline
functions is left to the compiler, inline is anyway only a hint to the
compiler.

https://github.com/torvalds/linux/blob/master/Documentation/process/4.Coding.rst#documentation

"Anybody who reads through a significant amount of existing kernel code will
note that, often, comments are most notable by their absence. ... That
said, there is little desire for verbosely-commented code. The code
should, itself, be readable, with comments explaining the more subtle
aspects".

So apart from what I already said before, useless documentation doesn't
help and is additional burden to maintain. So exercise judgement in adding
documentation.

I really don't see why this should be needed at all. Anyway I have nothing
to add to what I already said previously.

Hi Harish,

Still reviewing but here's the next set of review comments. Since this is a
huge 800 line patch, I'll just keep sending comments in email about section
of the code I am able to review, so that you can continue to work on
addressing the review comments in parallel.

I will also drop most people on the Cc: from these emails in the
future. Let them read the email on the intel-xe mailing list if interested.

Hmm this switch statement is not needed. This is just:

If you need this check, can we use BUILD_BUG_ON(per_xecore_buf_size ...)
here? Or skip the check, this is an internal variable, we don't get this
from userspace, correct?

Wondering if this should be a bit in xe_graphics_desc? Anyway we can live
with this for now.

Also why is this check here in locked()? It should be the first check in
xe_eu_stall_stream_open?

This check should also be xe_eu_stall_stream_open.

Please reorder the checks and distribute them correctly between open and
open _locked. locked() should only contain checks where we need to hold the
lock. See xe_oa.c for similar checks there.

I will review the error rewinding etc in the next rev since it will change
with the reordering.

Why not call this sampling_rate_mult or something like that? eu_stall_ is
an unnecessary repetition, everything here is eu_stall!

Let us call this buf_lock or ptr_lock or something like that.

I don't like generic names like 'lock' because it makes it really hard to
search the code for the locks when they are just named 'lock'.

Overall the priority should be on fixing code, rather then remaking the
patches (moving code around from one patch to another etc.), specially if
remaking the patches is significant effort. We can mostly live with the
patches as they are and review as we are doing now (even though it is not
ideal).

No need to set to NULL, we will free stream after this.

If this fails, this needs to return error. See xe_oa.c.

Also we need to only get RENDER forcewake or XE_FORCEWAKE_ALL?

Doesn't it make more sense to do this during enable rather than disable? So
we'll start from a clean place? Anyway, if this works in disable, probably
ok too.

Why can't we just write 0 here? Then we can remove the enable param from
gen_eustall_base.

So there is an interesting point here. if we are not going to do any
processing directly in the hrtimer interrupt, and are going to a schedule a
work item, why do we need the hrtimer at all? We can just make
buf_check_work a delayed_work, just call queue_delayed_work() to requeue
the work every 5 msec from the work_fn.

There are plenty of examples of this but e.g look at
amdgpu_amdkfd_restore_userptr_worker().

So I think we can and should remove hrtimer, just make buf_check_work
delayerd work. You already have a dedicated buf_check_wq (so are not using
a system_wq).

Why don't we just write 0 here? The real value will anyway be set during enable()?

Sorry I don't know this mocs business very well. Can you explain what's
going on here? Why do we program mocs.uc_index, what does it do and why are
we multiplying by 2?

Also s/base_reg_value/reg_value/ or something like that, since we are
reusing the variable to not just set XEHPC_EUSTALL_BASE.

Why '<< 1'? Is it to preserve the rollover bit?

This line has no effect, it is being overwritten it in the next line right
below :/

Is the last arg here write_ptr, or is it read_ptr_reg set in the previous line?

Why do we need to do all this, read the write ptr reg and write to read ptr
register? Can't we just set both read and write ptr to the start of the per
xecore buf address?

Something like this vaddr (with shifts) should be written to read/write ptr
register imo, to initialize read/write ptrs to the start of the per xecore
buffer?

We also need to carefully see which of this stuff needs to be in init() and
what needs to move to enable(). Because according to uapi, a stream can be
disabled/enabled multiple times and that should work.

E.g. should read/write pointers get reset during disable/enable? To me it
looks like most of the stuff here (except buffer allocation etc.) should
really be in enable() instead of init() (xe_oa.c follows a similar logic).

nit but imo it might be better to return 0 from these enable/disable
functions, but anyway this is also ok.

enable() anyway needs to return error from xe_force_wake_get.

Hi Harish,

Reveiw #4 on the same patch. Final review on this version of the patch. I
have suggested some low level code changes which should work but would need
to be verified (the code, as well as tested).

Also, I don't understand really what's going on in these circ buffer
functions with the overflow bits. So I need some explanation as to what the
code is doing and whether what's going on here is really correct.

So basically what I don't understand here is whether:

	if (write_offset > read_offset)

should really be

	if (write_offset >= read_offset)

Basically what happens when 'write_offset == read_offset'. We should be
using the overflow bits "somehow" according to me in this case but we don't
seem to be doing that.

This is repeated several times in my comments below. But if you have an
explanation just explain it here, don't have to repeat it each time.

See xe_oa_circ_diff. Surprised to see such a basic "bug" (though looks like
it is offset by other code so maybe not a real bug). Am I missing something
(e.g. because of the overflow bits)?

Though I think we should be using the overflow bits here to determine if
the buffer is empty or full. Why are we not doing that?

Basically what happens when 'write_offset == read_offset'? Shouldn't we
look at overflow bits to figure out if buffer is empty or full?

Check for the first condition is not needed after the suggested change to
buf_data_size above.

Ideally all this handling of dropped data should be in the -EIO patch. So
that should become the dropped packet handling patch. But anyway, let's
focus on the code, not the patches.

No need I think again, remove this if statement and let the code fall
through. Let's avoid these if statements where possible.

Once again, why not >= ?

Replace the above code section with:

	size = buf_data_size(buf_size, read_ptr, write_ptr);

Maybe it makes sense to add the record size to the stream, so we don't need
to this platform check each time. We can just initialize the record size at
init time.

> +		size = count - *total_size;
> +		size = (size / record_size) * record_size;

Let's replace this code section by something like:

		xe_assert(xe, count >= *total_size);
		size = min_t(size_t, count - *total_size, size);
		size = (size / record_size) * record_size;
> +
> +	if (size == 0) {

Remove, again let the code fall through the if-else ladder
below. copy_to_user should handle 0 byte copies (i.e. ignore them). But
check that. Wouldn't this work?

These copies look correct to me. Though not sure if we should replace all
these error return with a 'goto exit' so that we have all returns from the
end of the function. Do mutex_unlock etc.  in exit. But anyway, probably ok
as is too.

This should not be needed (and if it is needed it should be in
xe_eu_stall_stream_read). It should get handled automatically in
xe_eu_stall_data_buf_read with suggested changes. If not let's see.

This is not needed. wait_event_interruptible automatically checks if cond
is true before waiting, it will not wait if cond is true. See

Generally speaking this doesn't work if user buffer is too small, in that
case we don't want user thread to block when it calls in the next time to
read. See bcad588dea538 . But since this is a corner case, I am ok fixing
this after the initial merge.

Let's have one or two centralized functions to do this everywhere rather
than compute read/write offsets everywhere. For example a correct
buf_data_size() function should return how many bytes are in the buffer,
taking into account whether the buffer is empty or full. And then this
function will be called everywhere where we need to do this. And we can
have more than one such centralized function. Similar to xe_oa_circ_diff
and xe_oa_circ_incr for OA.

As I mentioned earlier, entire dropped packet handling should be in this
patch, so we can see the entire logic around this. So data_drop struct
should be defined in this patch.

Since data_drop.mask is being touched elsewhere under xecore_buf->lock,
here also it should be accessed under the same lock. So this returning -EIO
should probably be moved into xe_eu_stall_stream_read_locked?

I don't think this logic is correct. We should set this to false only after
we have cleared all set bits (e.g. only after bitmap_weight) otherwise we
might keep returning -EIO multiple times?

If HW continues to drop data and keep setting the line, while we are
resetting the bit, it is possible bitmap_weight might never become 0. I
think that is ok, we have returned -EIO at least once to indicate to
userspace that it is not reading data fast enough and HW is dropping data.

Or we may return -EIO multiple times as is happening here, where
reported_to_user is set to 0 before all bits might have been cleared. So
what is happening here might be ok too.

To see this clearly and evaluate it is why I am saying move all of this
data drop handling and -EIO return into this one patch. So we can decide
which approach to take: return -EIO just once or return multiple times.

We can also maybe defer this patch and merge the other stuff first if it's
a separate patch.

So maybe this is ok, maybe not, anyway something to think about.

Same question about whether or not to retain this struct. Retain it if we
want to document this information otherwise drop it and just keep sizeof.

Are these comments needed? Other places with XE_WA don't have them? Anyway
should be ok.

Because we don't want to complicate this, here's another simple idea:

In eu_stall_data_buf_check(), when we see the drop bit set for a particular
dss, move the read pointer (effectively discarding any data from that dss)
and also clear_dropped_eviction_line_bit(), but the dss with dropped data
is saved off in data_drop.mask. So basically we are clearing and saving the
error condition. Discarding data from that dss might be ok, since HW has
already dropped data.

Now in the next read_locked, if any data_drop.mask bit is set, return -EIO
and clear data_drop.mask. This way we don't need
data_drop.reported_to_user. So this way the entire situation is cleared and
handled once we have returned -EIO.

If more data gets dropped before the next read, same process repeats and
-EIO will be returned again.

Why do these 3 functions have 3 different return types, when they all
return a size? Can't the return type for all just be size_t?

Rest of the stuff in this patch lgtm, apart from reordering the reserved
field in struct drm_xe_query_eu_stall stuff, I previously mentioned.

1. The code you are referring to calculates the size of data in a
non-empty circular buffer, i.e. when buffer read ptr != write ptr.
It is an unnecessary function call overhead to call buf_data_size()
when the buffer is empty (read ptr == write ptr).

2. read/write pointers contain the overflow bit, read/write offsets do
not contain the overflow bit. They are just offsets into the buffer.

3. When the buffer is full, write offset == read offset, but the
overflow bits are different. The if (write_offset > read_offset) has
an else size = buf_size - read_offset + write_offset; which gets
executed when buffer is full (write offset == read offset).

4. I can add in the documentation of buf_data_size() that it
should be called for non-empty buffers only.

5. I have verified with several examples that there is no bug in the
code you are referring to.

No. The else part gets executed for == case.

This function will be called only for non-empty buffers. I don't think
there is a bug in this code.

This function would not be called when the buffer is empty
(read ptr === write ptr). It is an unnecessary function call overhead to
call this for empty buffers.

The else part gets executed correctly when the buffer is full. I will
add a note in the function documentation that this function will be
called only for non-empty buffers.

There are checks in the code for buffer empty condition
(read ptr == write ptr). As long as there is data to read, the driver
reads, and no special handling is needed when the buffer is full.
HW needs to do special handling when the buffer is full.

The code below to calculate the size of the data in the buffer works
only for non empty buffers. So, this check is needed.

For == case, the else part gets executed which is correct for non-empty
buffers.

No. This check is to find out if the write pointer has wrapped around
the buffer which is correct.

See below about this.

OK, thanks for the explanation. I understand what's happening now and how
overflow bits work. So I can review the code better.

As I said earlier, we need less documentation and more self-explanatory
code :/

First, how much is a function call overhead? If it is a little bit, it is
still worth it if it makes the code easier to understand and maintain.

Second, how do you know if there's even a function call? The compiler might
have optimized the function call out. In fact, given that buf_data_size()
is called only from one place, I don't see how the compiler won't optimize
this function out.

Therefore this code needs to be added at the top of buf_data_size():

	if (write_ptr == read_ptr)
		return 0;

Since it readily answers the question of what happens when the pointers are
equal and when the offsets are equal.

As mentioned above, no documentation, add the code above.

Not needed if we use the modified buf_data_size() (as mentioned above and

Think about it, it's just a safety check. I think it may be worth it to
have the assert.

I think this is better and more self explanatory than the code you have.

OK, if you think it's useful in tracing the flow and it's not duplicating
the output in the trace.

I worded the commit message that this commit is about read() returning
-EIO when data is dropped. So, I didn't put all the data drop code in
this patch. Sure, I can reword the commit message and move the code
into this patch.

data_drop.mask is being accessed via set_bit(), clear_bit(), test_bit()
and bitmap_weight(). set_bit() and clear_bit() are atomic operations,
but test_bit() and bitmap_weight() are not atomic. So, not all the code
accessing the mask need to be under lock. The code that is under lock is
under the buffer lock, whereas xe_eu_stall_stream_read_locked() is under
gt->eu_stall->lock. So, moving this code into xe_eu_stall_stream_read_locked
would not make any difference. I think this code can exist outside of a
lock. If one read() just misses a data drop, the subsequent read would
report the data drop.

If the subsequent read() reads all the data from all the subslices, it
would clear all the bits. But if the user buffer is small and it doesn't
read all the data from all the subslices, some bits can continue to be
set and can cause multiple alternate -EIO returns. Ideally, the user
buffer should be big enough to accomodate all the data from the kernel
buffer.

Yeah, the "unit of functionality" is not returning -EIO, it is "dropped
data handling", so that whole unit should be in a separate patch. This one,
I don't want to compromise on.

OK, let me see what happens with my suggestion below (starting with "I had
also outlined another...") and then we can see if the locking will be ok or
not.

Afaik we are not exposing a minimum user buffer size in the uapi, but we
could too.

I had also outlined another simple way of doing this in my follow up to
this email, which doesn't have such issues. What do you think of that?

Starting patch series v6, the per subslice buffer size is being exposed
to the user space via the query IOCTL. Recommended user buffer size is:
number of subslices x per subslice buffer size which is same as the
kernel buffer size.

I don't think driver dropping data is a good idea. The HW drops data
only when the buffer is full. Even though HW drops some data, a buffer
full of day will be useful to the user space.

Recommended is one thing, requiring a particular minimum buffer size is
another. One idea would be to return an error from read() if we see a
buffer size smaller than the recommended. We could check if UMD's are ok
with that and enforce it in the driver.

Anyway, just an idea, not saying we have to do it. If we don't, it would be
good to have a test to make sure buffers smaller than the recommended are
not causing any other issue. Plus make sure the driver handles it
correctly, which as I commented earlier, at present it doesn't. I also said
we can fix that after the initial merge.

I don't see a how that can be true. If an app is using the data for
profiling, missing data would mean they might be mis-reporting hotspots
etc.

Have we checked with UMD's what they would do if they saw -EIO? Do they
e.g. abandon data collection? One option, if acceptable, is actually to
return -EIO and disable the stream and not return any more data after
returning -EIO, just return -EINVAL from read(). If that data is not useful
to UMD's, that is.

I will make another observation in this connection. Likely this is not an
issue if leave pollin set when we return from read when the user buffer was
small and we could not return all available data. But something to bear in
mind. Let us say we have 10 dss's. When we start returning data we always
start from dss 1. Say in a read call we start from dss 1 and return till
dss 5. In the next read call we again start at dss 1. It would be better if
we start at dss 6. So in first read call we return data from dss 1-5, in
the next read call from dss 6-10, and so on.

But maybe if there's no data in dss 1-5 since we already returned all data
in the previous call, we will be ok. If not, there's a chance dss 6-10 will
start dropping data because we are not reading those dss's frequently enough.

I'd prefer to keep them, as I've personally found it convenient to refer
to them while while writing the userspace reader of these samples. I'm not
aware of any other particular place that they can be found, other than
maybe some other public repo that uses the i915 version of this interface
(IGT, maybe?). I'd venture to guess that others trying to call this 
code are also going to be searching for these definitions in
`drivers/gpu/drm/xe` as well.

Yes, they are present in the IGT's too:

https://patchwork.freedesktop.org/patch/630656/?series=143030&rev=1

Would that work for you, or you prefer them in the kernel? Just trying to
get an idea right now, not deciding one way or another.

Thanks.

I think it'd be more convenient to have them in the Xe driver itself, since most
userspace users are going to already be looking there. They'd have to really
Google around to find those definitions in IGT. I understand that it cleans up
the code a bit to remove them (since we're only using their size), but keeping
them makes this code more self-documenting.
