[PATCH v3 0/2] drm/xe/guc: shrink and compress GuC snapshot dumps

[PATCH v3 0/2] drm/xe/guc: shrink and compress GuC snapshot dumps

[Zhanjun Dong]

GuC snapshot output is currently expensive in both size and latency: large
log buffers are emitted as raw ascii85, and the surrounding dump text
includes a bit of avoidable noise. This series makes xe snapshot dumps more
compact and easier to handle by compressing the large binary payloads,
tightening the textual output, and trimming the default GuC log size.

Select ZSTD_COMPRESS/ZSTD_DECOMPRESS in DRM_XE so the xe module pulls in
the zstd compressor when built.

Reduces the default GuC log buffer from 8MB to 2MB, which still preserves
useful history while cutting dump latency and dmesg load; with typical
compression, the emitted payload drops further.

History:
v3: Add Kconfig option to control compression of GuC log and CTB dumps,
    allowing users to choose between reduced dump sizes or lower memory
    usage.
    Remove "reduce GuC log size from 8MB to 2MB" patch, to be added later
    if needed.
    Replace pr_err with xe_gt_err and add more error print.
v2: Fix Kunit test error by selecting ZSTD_DECOMPRESS in DRM_XE config,
    required by zstd_is_error/zstd_get_error_name.

[PATCH v3 1/2] drm/xe: Remove extra newlines from LRC snapshot dump

[Zhanjun Dong]

The LRC snapshot printer adds an extra newline before the replay
offset and replay length lines. This leaves blank lines in the
HWCTX section of the dump.

Remove the stray newlines so the snapshot output remains compact
and consistently formatted.

[PATCH v3 2/2] drm/xe/guc: Compress GuC log and CTB dump with zstd

[Zhanjun Dong]

Replace the raw ascii85 dumps of GuC log snapshots with a
zstd-compressed ascii85 stream and reuse the same helper for CTB
snapshot output.

Use zstd streaming with default level-3 parameters and an estimated
source size of 0 so the compression workspace stays bounded even for
multi-megabyte logs.

Add a new Kconfig option DRM_XE_COMPRESS_DUMP to control whether
GuC log and CTB dumps are compressed with ZSTD. This allows users to
choose between reduced dump sizes or lower memory usage.

What is the advantage of doing this the KMD vs. getting the dump and
compressing it in user space before sharing it?

1. Timing impact
There are KMD runtime challenges about dump too many data:
a. Skip unused data.
Existing code dumps whole buffer, which also prints out area not used 
(Like lots of lines of "Z"). This patch only print valid range in buffer.
b. Compessed size
Test shown a typical 75% compression ratio about valid GuC log data.

Print out 10MB debug data in ascii85 take quiet a lot of time, 
especially when print out to dmesg. Too long print out might cause 
timing impact to runtime, which is bad for debug purpose.
With fewer data, this relifes KMD pressure when triggered.

2. UMD utility required
Do it in UMD requires an utility running in background and check/receive 
for data. If through debugfs, all above timing impact is not skipped.
This add extra step for CI and user, in case of utility missing/offline, 
the valueable issue data would be lost

Meanwhile, there is discussion to have that kind of utility, will keep 
monitoring it.

Re: [PATCH v3 2/2] drm/xe/guc: Compress GuC log and CTB dump with zstd

[Dong, Zhanjun]

Hi Matthew,

I wanted to follow up on this thread to see if there is any additional 
feedback on this topic I shared a few days ago.

If there is anything else holding us back from moving to the next stage, 
please let me know. I'd be happy to provide more context if needed.

Best regards,
Zhanjun Dong

When do we printk to dmesg - we should never be doing that afiak or we
do, that should be removed as dmesg is not a mechanism for scalable
error logging.

We always split the snap step from print step, so if a print takes a
little longer, I really don't see the issue.

That is not true. I have local repo with tools to decode GuC logs.

The answer must be yes, we have updated all internal tools, wikis before
we even considering merging this.

commit 08167fcfee22224e3617e0f23aadf1e405a23201
Author: Zhanjun Dong <zhanjun.dong@intel.com>
Date:   Mon Jun 29 13:22:39 2026 -0400

    drm/xe/guc: Compress GuC log and CTB dump with zstd
    
    Replace the raw ascii85 dumps of GuC log snapshots with a
    zstd-compressed ascii85 stream and reuse the same helper for CTB
    snapshot output.
    
    Use zstd streaming with default level-3 parameters and an estimated
    source size of 0 so the compression workspace stays bounded even for
    multi-megabyte logs.
    
    Add a new Kconfig option DRM_XE_COMPRESS_DUMP to control whether
    GuC log and CTB dumps are compressed with ZSTD. This allows users to
    choose between reduced dump sizes or lower memory usage.
