[PATCH v3 2/3] gpu: nova-core: select RUST_FW_LOADER_ABSTRACTIONS
Posted by Alexandre Courbot 1 month, 1 week ago
RUST_FW_LOADER_ABSTRACTIONS was depended on by NOVA_CORE, but NOVA_CORE
is selected by DRM_NOVA. This creates a situation where, if DRM_NOVA is
selected, NOVA_CORE gets enabled but not RUST_FW_LOADER_ABSTRACTIONS,
which results in a build error.

Since the firmware loader is an implementation detail of the driver, it
should be enabled along with it, so change the "depends on" to a
"select".

I just encountered this testing 6.19-rc1, and was pleased to discover
this patch had already been submitted.

Tested-by: Alyssa Ross <hi@alyssa.is>

And it probably also makes sense to add this now that the kernel test
robot has also found it:

Closes: https://lore.kernel.org/oe-kbuild-all/202512061721.rxKGnt5q-lkp@intel.com/

(I suppose it doesn't make sense to add the Reported-by suggested there
since your patch predates that report.)

I see that the first patch from this series has already been picked up
by Greg, but this and patch 3 are still waiting.  Is that correct?

Thanks! Both tags added.

After rebasing on top of -rc1, I can confirm. This patch is going to be
taken through the Nova tree. Patch 3 is available for the relevant
maintainers to take.

Pushed this patch with added taggs and Danilo's Acked-by (received on
Zulip) to drm-rust-fixes, thanks!
