Linux 6.18 To Introduce Pixpaper DRM Driver, boot_display DRM Attribute
Thomas Zimmermann of SUSE sent out today what is anticipated to be the last drm-misc-next feature pull request for DRM-Next that is targeting the upcoming Linux 6.18 kernel cycle.
Today's drm-misc-next pull request brings a new DRM display driver: Pixpaper. The Pixpaper DRM display driver is for supporting the Mayqueen Pixpaper e-ink panel. This e-ink display panel features a 122x250 resolution and XRGB8888 format while communicating via SPI. The Mayqueen Pixpaper is found in various low-power embedded environments.
Another notable change with today's DRM pull request ahead of Linux 6.18 is adding the "boot_display" sysfs attribute. This is moving it out of the PCI subsystem and into the DRM area. The boot_display attribute is set if a display is connected to the device and was used to display the boot sequence.
This final drm-misc-next feature pull for Linux 6.18 also adds a TTM interface for populating buffers and in turn the Intel Xe and Nouveau drivers are using it to pre-populate exported buffers. The AMDXDNA accelerator driver meanwhile for Ryzen AI NPUs adds a new DRM_IOCTL_AMDXDNA_GET_ARRAY ioctl.
