[PATCH v2 0/1] Add support for EU stall sampling

[Ashutosh Dixit]

 The following patch adds 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. More details are explained in the patch
commit message.

I am posting this patch as an RFC to get early feedback in the uAPI
while support for this feature is being added into Mesa. A new test
in the IGT repo: https://gitlab.freedesktop.org/drm/igt-gpu-tools.git
is also under development to test this feature in the driver. This
patch has undergone basic testing with the new IGT test that is under
development.

The EU stall data from the driver include a header with additional
information about the data that follows the header. The header
includes flags one of which indicate if data has been dropped has
been dropped by the hardware due to buffer being full. While read
returns the total bytes read, any data dropped by the hardware will
be indicated in the flags. One feedback received so far is to make
read return an error when data has been dropped by the hardware
instead of setting a flag in the header. One suggestion received
is to consider two FDs per EU stall data stream with one fd to read
data and other fd to pass any errors. please comment on this idea
that's not represented in the code

Thank You.

[PATCH v2 1/1] drm/xe/eustall: Add support for EU stall sampling

[Ashutosh Dixit]

From: Harish Chegondi <harish.chegondi@intel.com>

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 architecture GPUs - LNL and BMG.

Use an existing IOCTL DRM_IOCTL_XE_OBSERVATION as interface into the driver
from the user space to do initial setup and obtain a file descriptor for
the EU stall counter 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
DRM_XE_OBSERVATION_IOCTL_ENABLE and DRM_XE_OBSERVATION_IOCTL_DISABLE
IOCTLs.  User space can also call poll() to check for availability of
data. The data can be read with read(). EU stall data consists of header
and data pairs. The header format is defined in struct
drm_xe_eu_stall_data_header. 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 up and if the hardware wants to write data, it simply drops data due
to unavailable buffer space. In that case hardware sets a bit in a
register.  The driver sets a flag in the EU stall data header flags field
to let the user space know that the hardware has dropped data.

why CACHELINE_BYTES?
I would expected it to be the same size as drm_xe_eu_stall_data_xe2.
If it is for performance optimization then add reserved fields to drm_xe_eu_stall_data_xe2 until it is the same size as CACHELINE_BYTES.

eventhough only the first 100 to 120 bits approximately have valid data.
The rest of the record is zeros.

One question to resolve is if we really need this header and if UMD's are
actually using the information in this header. In OA we dropped the
header and are providing information in the header via different means (see
below).

Another option is to actually add a property for the header. So headers are
added only when user space requests headers.

Do UMD's use this subslice information? We should check with L0 and Mesa
about this.

Also about whether UMD's need or want the header itself. For OA, UMD's were
happy not having to parse the header.

In OA such information is returned via DRM_XE_OBSERVATION_IOCTL_STATUS. For
EU stall, e.g. we could return a bit mask of subslices which reporting
drops. So similar to OA, we could return -EIO when HW reports drops and
userspace optionally issues DRM_XE_OBSERVATION_IOCTL_STATUS to retrieve
which subslices are reporting drops.

This is static information. Does it need to be in each packet header?
E.g. it can be returned via DRM_XE_OBSERVATION_IOCTL_INFO after a EU Stall
stream has been opened.

The INFO data struct could also include a capabilities field. So if new
features are added to EU stall in the future, they would be advertized to
user space using the capabilities field.

This will not be needed if just return raw EU Stall data without
headers. Or even otherwise it is probably not needed, it is the total size
of returned data minus the size of the header. Provided we return all
available data.

This can be handled via 'extensions'. And if headers change they can be
advertized in capabilities.

[MAC] L0 does not currently use this. 

Also about whether UMD's need or want the header itself. For OA, UMD's were happy not having to parse the header.

So similar to OA, we could return -EIO when HW reports drops and userspace optionally issues DRM_XE_OBSERVATION_IOCTL_STATUS to retrieve which subslices are reporting drops.

[MAC] having a return code to notify of reports drops would be much preferable. This would allow the UMD detecting this condition during the read phase without needing to process/parse each report.

This is static information. Does it need to be in each packet header?
E.g. it can be returned via DRM_XE_OBSERVATION_IOCTL_INFO after a EU Stall stream has been opened.

[MAC] since the size is constant, it seems an overhead including the info in every report. 

The INFO data struct could also include a capabilities field. So if new features are added to EU stall in the future, they would be advertized to user space using the capabilities field.

> +	/** @num_records: number of records following the header */

This will not be needed if just return raw EU Stall data without headers. Or even otherwise it is probably not needed, it is the total size of returned data minus the size of the header. Provided we return all available data.

[MAC] the KMD will always return atomic units of reports, right? Then this is not needed, having UMD the possibility to query report size when opening the stream, the UMD can know how many reports are in each read.

This is not what I meant, these comments are more in the nature of code
reviews. What I meant was review of the uapi itself. E.g., following the
discussion below, what we are interested in is things like:

a. Whether Mesa is actually consuming fields in the EU Stall header which
   KMD appends to EU stall packets sent to user space.
b. Whether Mesa prefers to parse the header or get status from a return
   code

So things like that. It would be great if someone from Mesa could respond
to my original email and address the points raised there.

Thanks.

Felix's MR[1] is only using record_size and num_records, if the drm_xe_eu_stall_data_xe2 was the same size and the sample we would not need the header
at all, inline replies below.

But what can UMD do when that is set?
I would rather have a warn once printed on dmesg, so the issues don't go silent but it don't need to go to the uAPI.

drm_xe_eu_stall_data_xe2 should be of the same size as record_size so it can also be dropped.

Same as above, would not be needed if drm_xe_eu_stall_data_xe2 matches samples size.

Matias: could you please explain what L0 does with this dropped flag?

Harish: do we know what is the reason HW sets this dropped flag? Is it
because userland is not reading fast enough so HW is forced to drop data?

Mesa can ignore this if they don't need it.

dmesg warn is likely not an option because it will trigger bugs in our

RE: [PATCH v2 1/1] drm/xe/eustall: Add support for EU stall sampling

[Cabral, Matias A]

> Matias: could you please explain what L0 does with this dropped flag?

During the processing of the data, L0 returns a warning message. VTune ( I think) also warns the user that results were collected but will be inaccurate because the draining/reading of data was not done fast enough. By moving the warning to be returned at earlier/reading step, VTune may a) on the fly increase the reading frequency reducing the amount of data lost b) cancel the collection immediately, saving time to the user that may collect data in one node and process in a different one. 

Thanks,

Re: [PATCH v2 1/1] drm/xe/eustall: Add support for EU stall sampling

[Harish Chegondi]

Here is the summary of the discussion regarding the uAPI

1. Eliminate the data header from the data copied by the 
driver to the user space.

2. Subslice information in the header is NOT used by the user space since
the data is collected at the tile granularity.

3. The only flags bit(0) in the header currently used, is to indicate if
the HW has dropped any EU stall data due to insufficient space in the
kernel buffer. Instead of a flag in the header, the driver would return
an error during a read() if *any* subslice in the tile has dropped data.
Any EU stall data present in the kernel buffer would NOT be read.
The subsequent read() would return EU stall data for all subslices on
the tile and also clear the drop bit in the HW registers for all
subslices that dropped data.

4. User space doesn't seem to be interested to know which subslices have
dropped data. So, the driver would not provide any STATUS IOCTL to get
this info.

5. Record size in the header is a static info which can be queried
through an INFO IOCTL after a file descriptor is opened. Based on the
GPU, user space can determine this as well.

Thanks
Harish.

RE: [PATCH v2 1/1] drm/xe/eustall: Add support for EU stall sampling

[Ranjan, Joshua Santhosh]

Hi Harish, 

One clarification:
> the driver would return an error during a read() if *any* subslice in the tile has dropped data.
>Any EU stall data present in the kernel buffer would NOT be read.
> The subsequent read() would return EU stall data for all subslices on the tile and also clear the drop bit in the HW registers for all subslices that dropped data.

Just to confirm, in case of buffer overflow 2 read() calls are expected to be done to read out the stall data ?

RE: [PATCH v2 1/1] drm/xe/eustall: Add support for EU stall sampling

[Cabral, Matias A]

Hi Santhosh, 

> Just to confirm, in case of buffer overflow 2 read() calls are expected to be done to read out the stall data ?
Yes, this will be handled internally by the UMD. The user calling L0 won't know this happened under the hood. 

Hi Harish, 

>4. User space doesn't seem to be interested to know which subslices have dropped data. So, the driver would not provide any STATUS IOCTL to get this info.
During the discussion the question came around the fact if in reality this can actually happen, since both slices are sampling at same frequency and active threads state do produce reports. You mentioned you would check with HW team. 


ETA for this changes pushed upstream ? 

Thanks, 
_MAC

Here is the summary of the discussion regarding the uAPI

1. Eliminate the data header from the data copied by the driver to the user space.

2. Subslice information in the header is NOT used by the user space since the data is collected at the tile granularity.

3. The only flags bit(0) in the header currently used, is to indicate if the HW has dropped any EU stall data due to insufficient space in the kernel buffer. Instead of a flag in the header, the driver would return an error during a read() if *any* subslice in the tile has dropped data.
Any EU stall data present in the kernel buffer would NOT be read.
The subsequent read() would return EU stall data for all subslices on the tile and also clear the drop bit in the HW registers for all subslices that dropped data.

4. User space doesn't seem to be interested to know which subslices have dropped data. So, the driver would not provide any STATUS IOCTL to get this info.

5. Record size in the header is a static info which can be queried through an INFO IOCTL after a file descriptor is opened. Based on the GPU, user space can determine this as well.

Thanks
Harish.

VTune ( I think) also warns the user that results were collected but will be inaccurate because the draining/reading of data was not done fast enough. By moving the warning to be returned at earlier/reading step, VTune may a) on the fly increase the reading frequency reducing the amount of data lost b) cancel the collection immediately, saving time to the user that may collect data in one node and process in a different one.

Hi Matias, I did check on this and I was told that different threads
have different cache hit/miss profiles and therefore generate different EU
stall data. So, in theory all subslices with EU stall data may not have
dropped data at the same time. But in reality this may not be the case.
This would be a good thing to check during testing.
Would user space be interested in knowing which subslices have dropped
data?

My plan is to make the uAPI changes and address other review comments
and push the next version of the patch by the end of next week.

I haven't really looked at this patch in detail, but one drive-by
comment:  we shouldn't be open-coding this assignment.  There's now a
dss_per_group() in xe_gt_mcr.c that determines this in a future-proof
manner that will continue to work even if future platforms change the
physical layout.  You probably don't want to call that function on every
read, but you can call it once and stash the value somewhere to be
re-used later.

Although I also wonder if we even want to be directly working with
steering targets at this level of the code.  It seems like the per-DSS
accesses are common enough in this eustall code (and also other upcoming
stuff like eudebug) that maybe it would make more sense to add a
dedicated xe_gt_mcr_unicast_read_dss() helper to the MCR library to
reduce the duplicated complexity in these other components.

commit dc4e0d1d5ac604330391460728a91e9e586e4061
Author: Harish Chegondi <harish.chegondi@intel.com>
Date:   Sun Jul 7 15:41:41 2024 -0700

    drm/xe/eustall: Add support for EU stall sampling
    
    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 architecture GPUs - LNL and BMG.
    
    Use an existing IOCTL DRM_IOCTL_XE_OBSERVATION as interface into the driver
    from the user space to do initial setup and obtain a file descriptor for
    the EU stall counter 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
    DRM_XE_OBSERVATION_IOCTL_ENABLE and DRM_XE_OBSERVATION_IOCTL_DISABLE
    IOCTLs.  User space can also call poll() to check for availability of
    data. The data can be read with read(). EU stall data consists of header
    and data pairs. The header format is defined in struct
    drm_xe_eu_stall_data_header. 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 up and if the hardware wants to write data, it simply drops data due
    to unavailable buffer space. In that case hardware sets a bit in a
    register.  The driver sets a flag in the EU stall data header flags field
    to let the user space know that the hardware has dropped data.

maybe not an RFC anymore?

if dropped data can be mapped to an intuitive error in the return of 
read, we should definitely do that. If multiple headers are returned in 
a read call and only some header blobs are affected, then, IMO, we 
should also set the flag for the relevant headers.

If it is just one stream of data, then I would avoid an additional FD 
for passing errors. Read should be able to handle returning errors. Is 
there a limitation in the generic file ops (like read()) that EU stall 
supports? Are errors very common when consuming EU stall data?
