| Summary | 0001415: Please enable CONFIG_UDMABUF | ||||
| Description | It enables the userspace dmabuf misc driver so Qemu can use this to create host dmabufs for guest framebuffers. | ||||
| Steps To Reproduce | Blob resources in QEMU have been enabled in EL9.3: https://bugzilla.redhat.com/show_bug.cgi?id=2032406 Adding 'blob="on"' to the video section of a libvirt XML configuration: <video> <model type="virtio" heads="1" primary="yes" blob="on"/> <address type="pci" domain="0x0000" bus="0x00" slot="0x01" function="0x0"/> </video> leads to this error when it is run under kernel-lt: Error starting domain: Path '/dev/udmabuf' is not accessible: No such file or directory | ||||
| Additional Information | It has been enabled since at least EL9.1 upstream: $ grep UDMABUF /boot/config-* /boot/config-5.14.0-162.6.1.el9_1.0.1.x86_64:CONFIG_UDMABUF=y /boot/config-6.1.69-1.el9.elrepo.x86_64:# CONFIG_UDMABUF is not set | ||||
| Tags | No tags attached. | ||||

Acknowledged. We will enable it in the next kernel update for both kernel-lt and kernel-ml. CONFIG_UDMABUF=y |
