I noticed that in the vulkan branch, README.intel-vulkan.txt suggests using `export VK_ICD_FILENAMES="$MESA_TOP/src/vulkan/anv_icd.json"` (<a title="Ctrl+Click or tap to follow the link" href="https://cgit.freedesktop.org/mesa/mesa/tree/README.intel-vulkan.txt?h=vulkan&id=698ea542830ba0d56e514492fbdf73e3898d4c17#n87">link</a>). However, there doesn't seem to be a anv_icd.json file anywhere in the repository. I tried `export VK_ICD_FILENAMES="$MESA_TOP/src/intel/vulkan/dev_icd.json"`, which seemed to work better. I presume somebody just forgot to update the readme after changing the name. Of course, vulkaninfo still fails. It just gets further than it did before. I'm a little stuck on the next error: anv_device.c:66: failed to open /dev/dri/renderD128: Permission denied (VK_ERROR_INITIALIZATION_FAILED) I haven't changed its permissions from the defaults it came with: 'crw-rw---- 1 root video 226, 128 Feb 18 16:18 /dev/dri/renderD128'. Any suggestions? Did I miss something I needed to do? Thanks, Cory Bloor </div> </body> </html>
