[PATCH 1/2] mesa: add PROVIDES for Vulkan and OpenCL ICDs

[Dmitry Baryshkov]

In order to let BSPs easily select OpenCL and Vulkan Installable Client
Drivers, add two virtual package names: virtual-opencl-icd and
virtual-vulkan-icd.

[PATCH 2/2] vulkan-loader: depend on the Vulkan ICD package

[Dmitry Baryshkov]

Instead of pulling Mesa Vulkan drivers via RRECOMMENDS, make use of the
new virtual-vulkan-icd package name, letting BSP layers specify a
differnt preferred Vulkan driver.

Hi Dmitry,

Thanks for your patches.

It looks like it is introducing some build issue:

ERROR: core-image-sato-sdk-1.0-r0 do_rootfs: Unable to install packages. Command '/srv/pokybuild/yocto-worker/qemuarm64-alt/build/build/tmp/work/qemuarm64-poky-linux/core-image-sato-sdk/1.0/recipe-sysroot-native/usr/bin/opkg --volatile-cache -f /srv/pokybuild/yocto-worker/qemuarm64-alt/build/build/tmp/work/qemuarm64-poky-linux/core-image-sato-sdk/1.0/opkg.conf -t /srv/pokybuild/yocto-worker/qemuarm64-alt/build/build/tmp/work/qemuarm64-poky-linux/core-image-sato-sdk/1.0/temp/ipktemp/ -o /srv/pokybuild/yocto-worker/qemuarm64-alt/build/build/tmp/work/qemuarm64-poky-linux/core-image-sato-sdk/1.0/rootfs  --force-postinstall --prefer-arch-to-version   install kernel-devsrc opkg packagegroup-base-extended packagegroup-core-boot packagegroup-core-eclipse-debug packagegroup-core-sdk packagegroup-core-ssh-openssh packagegroup-core-standalone-sdk-target packagegroup-core-tools-debug packagegroup-core-tools-profile packagegroup-core-tools-testapps packagegroup-core-x11-base packagegroup-core-x11-sato psplash run-postinsts ssh-pregen-hostkeys' returned 1:
Solver encountered 1 problem(s):
Problem 1/1:
  - package packagegroup-core-tools-testapps-1.0-r0.qemuarm64 requires mesa-demos, but none of the providers can be installed
  - package mesa-demos-9.0.0-r0.cortexa57 requires libvulkan1 >= 1.4.321.0, but none of the providers can be installed
  - conflicting requests
  - nothing provides virtual-vulkan-icd needed by libvulkan1-1.4.321.0-r0.cortexa57

Solution 1:
  - do not ask to install a package providing packagegroup-core-tools-testapps

Can you have a look at this issue please?

Thanks,

I see. The config requires vulkan feature, but Mesa doesn't provide
vulkan drivers, so there is no mesa-vulkan-drivers package (and thus no
virtual-vulkan-icd provider).

I'll keep RRECOMMENDS, making sure that it's possible to build the
system wthout actual Vulkan drivers.
