Linux 5.14 will support Hyper-V DRM display driver

by ddos · June 10, 2021

According to the mailing list, a new Hyper-V DRM display driver has been included in this week’s drm-misc-next PR and will be merged into the Linux 5.14 mainline.

The Hyper-V DRM display driver was originally released by a Microsoft engineer last summer. At that time, the driver was only a port of the Hyper-V Linux frame buffer (hyperv_fb) driver, many advanced functions such as hardware cursor, EDID, multiple dirty areas, etc. are not yet supported. After several rounds of development and code review, the Hyper-V DRM display driver is about to be merged into the future Linux 5.14 kernel.

This open-source Direct Rendering Manager display driver is used to support Microsoft’s Hyper-V composite video device for display output in its virtualized environment and is now a DRM driver that can work with Wayland synthesizers, etc. The driver only uses more than a thousand lines of code to make the kernel mode setting (KMS) work well in the Hyper-V virtual machine.

Now, the Hyper-V DRM display driver is being merged into the DRM-next tree. If nothing happens, it will be merged into Linux 5.14 when the merge window opens in a few weeks. In addition, in this drm-misc-next PR, there are some refactorings of TTM memory management code, document updates, and various fixes to the smaller direct rendering manager driver.
