Looks fine to me. This is on the 4.19 and master branches
of the kernel-cache.
Thanks Bruce!
I'll send SRCREV bumps for those kernel versions shortly.
Do you mind if I do it? I have a patch ready now to bump the SHA and
add qemuriscv64 as a supported machine.
I have it queued with a number of other changes, so it needs to
come along with that SRCREV bump.
Ah, no worries then.
Otherwise if you do can you add qemuriscv64 as compatible.
I'd have to test it first before I could add that. What would be
the steps to do that ? Is everything else in oe-core ?
We would also need to add the qemuriscv64 machine in order to build it.
The only thing we are missing after that is the bootloader, which
isn't in oe-core. We are working on a improved boot flow for RISC-V so
the current boot loader will probably never go into oe-core.
Gotcha.
I'm just tidying up the other changes. I do expect to have them
out today. So the wait won't be too long!
