Tried the scanout patch on kernel 7.2.0. Confirmed running:
`[drm] Initialized vmwgfx 2.22.0`.
No change here. GPUActive from /proc/meminfo:
5 RDP sessions, 39 min open: 0.70 -> 3.97 GB
then 42 min at zero sessions: 3.92 -> 4.73 GB
Not a single sample went down. Same as on 2.21.
It also keeps growing with zero sessions and small usage of the machine,
so RDP is a good trigger, not the only one.
Build details if useful: distribution kernel (CachyOS 7.2.0-1), vmwgfx
built out-of-tree from the matching source with clang 22.1.8, no LTO.

Hi Maaz,
Short version: mesa 26.2.1 is running here with 3D on, and the leak is still
there.
Setup: one boot, 119 h, a single kwin_wayland (6.7.4), mesa 3:26.2.1-1, kernel
7.2.0, renderer SVGA3D.
TTM sys+mob 0.36 -> 16.73 GB
objects 1948 -> 10365
kwin_wayland holds 8484 MB in 4894 objects
free RAM 4.9 of 31 GB - we have to reboot today
It tracks rendering, not uptime. Idle nights (02:00-07:00) in this same boot:
22 Aug -0.03 GB 25 Aug +0.00 GB
23 Aug +0.02 GB 26 Aug +0.04 GB
24 Aug +1.88 GB <- the one night an automated GUI test run was active
The surface warning still fires: 1168 WARNING blocks at
vmw_surface_handle_reference in the last 27 hours. That is a window, not a
total - journald has already rotated away the earlier part of this boot.
Correction to my previous mail: "four times during session startup" was wrong.
It fires in bursts throughout the session.
We have not tried "drm/vmwgfx: Return gem fd handle for scanout buffers" we run
distribution kernels here. Say the word and we will build it.
Yes please, can you go ahead and try that patch, it fixes some errors on kde
and might fix this issue you are facing too.
Best regards,
Jellis

For the 3D-enabled case, could you try with mesa 26.1.8 or 26.2.1, both of
which contain my fix.
Also if you could try the patch I just submitted on dri-devel - drm/vmwgfx:
Return gem fd handle for scanout buffers.
If you still see issues with these patches, let me know.
As for the 3D disabled case, I can see issues on my local machine and am
working on a fix.
PS - Your emails are overly verbose and narrative, could you include only the
actual problems you are facing.
If you're using an llm to write these, please make them more terse and human
readable. Thanks.
