With this week's pull there is now more accurate engine busyness metrics for modern Intel integrated/discrete graphics relying on the GuC micro-controller submission. Some race conditions and bugs were discovered within the GuC engine busyness handling that resulted in a range of issues. But with the patches now in drm-intel-gt-next, that should all be fixed up for better reporting the engine busyness metrics.
Separately, this pull request also has a fix to ensure partial buffer object segment offsets never exceed the allowed maximum size, flushing the GuC CT receive tasklet during reset preparations, and a variety of debugging improvements and code clean-ups.
More details on these Intel GT updates for the week of new material for Linux 6.14 can be found via this pull request .
