The open-source upstream driver support for the Qualcomm Adreno X1-45 that is used by the Snapdragon X1 Plus 8-core SoC appears ready for the mainline kernel and could be all aligned for the upcoming Linux v6.18 kernel cycle.
The past few months saw Qualcomm engineers preparing open-source driver support for the X1-45 GPU to complement the X1-85 GPU support found in the flagship X1 Elite SoC. After four rounds of patch review the X1-45 GPU support appears all set and could make it for the next kernel version.
Per the v4 patch series message:
“Add support for X1-45 GPU found in X1P41200 chipset (8 cpu core version). X1-45 is a smaller version of X1-85 with lower core count and smaller memories. From UMD perspective, this is similar to “FD735” present in Mesa.
Tested Glmark & Vkmark on Debian Gnome desktop.”
The Snapdragon X1 Plus and such X1P laptops aren’t as well supported under Linux currently as the premium X1 Elite models. But then again even for the X1 Elite laptops a range of issues persist.
The news this week on the X1-45 driver front is Bjorn Andersson commenting he picked up the X1-45 Device Tree additions while the MSM DRM driver changes are awaiting for pulling by Rob Clark. They hadn’t hit the MSM-Next code yet but with the DT patches having been queued up it’s suspected the MSM DRM driver patches will also in turn land for Linux 6.18 later in the year.
