Bug ID: 14946
Summary: Missing dependencies for virgl xorg configuration
Product: buildroot
Version: 2022.05.1
Hardware: PC
OS: Linux
Status: NEW
Severity: normal
Priority: P5
Component: Other
Assignee: unassigned@buildroot.uclibc.org
Reporter: tobias.roehmel@rwth-aachen.de
CC: buildroot@uclibc.org
Target Milestone: ---
Hi all,
I was trying to run buildroot on AARCH64 softmmu Qemu with X-server and virgl
graphics acceleration and found out that it doesn't work without these 2
configurations: BR2_PIC_PIE (RELRO Protection=none) BR2_PACKAGE_LIBEPOXY.
My buildroot configuration is qemu_aarch64_virt_defconfig + the graphics stuff
as in the attachment.
If RELRO Protection is enabled, the X-server loads libraries in such an order
that virtio_gpu_dri.so (the virtio GPU driver) is not found.
If BR2_PACKAGE_LIBEPOXY is not enabled, xorg is built without glamor_gbm which
makes the dri2 initialization for the driver fail.
I'm not a graphics expert so I don't know if this is somehow intended. I think
it would be easier if these dependencies would be sorted out automatically.
The Qemu I used is upstream with the following configure:
configure --target-list=aarch64-softmmu --enable-debug --enable-opengl
--enable-virglrenderer --enable-gtk --enable-sdl
and the following command:
qemu-system-aarch64 -machine virt -cpu max -kernel Image -serial mon:stdio -m
size=4G -device virtio-gpu-gl-pci -display sdl,gl=on
Best regards,
Tobias
