okay so bestie, buckle up, because this is the amdgpu_gfx_...ng_begin_use(9) page from the Kernel API Manual and it's honestly kind of a baddie π
πΈ NAME πΈ
amdgpu_gfx_enforce_isolation_ring_begin_use β the "begin use" moment for a ring, but make it enforced isolation β¨ lowkey the whole point is that this ring knows how to share π«Ά
π¦ SYNOPSIS π¦
void amdgpu_gfx_enforce_isolation_ring_begin_use (struct amdgpu_ring
*ring );
that's it. that's the whole signature. no cap π
π ARGUMENTS π
ringβ a pointer to thestruct amdgpu_ringstructure. like, the actual ring. the main character of this function tbh π
π DESCRIPTION π
so here's the tea β β this is the ring begin_use helper implementation for gfx, and what it does is serialize access to the gfx IP between kernel submission IOCTLs and KFD user queues whenever isolation enforcement is enabled π₯
basically: when both of those are active, they each get a time slice. sharing is caring, bestie, and this function is the one holding the clipboard πβ¨
fr fr, the word "enforce" is right there in the name β this isn't vibes-based access, it's enforced isolation, iykyk π
