Intel Continues Enabling The GPU D-Series "Crescent Island" Driver Support For Linux 7.5

Intel's intriguing Crescent Island Xe3P-based AI accelerator hardware now known as the Intel GPU D Series continues seeing a lot of Linux kernel driver activity. The upcoming Linux 7.5 kernel is continuing to build out the support for this upcoming hardware. Intel software engineers have been pushing out Crescent Island driver patches for Linux since last year and began just weeks after Intel announced Crescent Island that October. A year later as new work toward Linux 7.5, which will be the first stable kernel series of 2027, there is more enabling in place. The latest drm-xe-next pull request submitted to DRM-Next lands temperature sensor handling for the Xe hardware monitoring (HWMON) code, platform-reported VRAM thermal channels, PCIe and memory controller temperature support, and other sensor work. Also coming for the Intel GPU D Series in Linux 7.5 is Common Platform Error Record (CPER) logging support of RAS errors. There is also OOBMSM telemetry "OCode" late binding support being added for Crescent Island. Additionally, handling for memory double-bit ECC errors. More details on these latest Intel GPU D Series / Crescent Island additions and other Xe driver changes accumulating for Linux 7.5 can be found via this pull request.
