DCDEBUGMASK (UINT)(9)

💅 dcdebugmask (uint) 💅

okay bestie, welcome to the dcdebugmask (uint) page from the Kernel API Manual, section 9. This is the little group chat where the kernel talks about debug options. ✨

What does it do? It displays debug options — that's the whole vibe. For the actual enum, go peek at DC_DEBUG_MASK in drivers/gpu/drm/amd/include/amd_shared.h, iykyk. 🫶

🌈 SEE ALSO 🌈

okay so the kernel file is ./drivers/gpu/drm/amd/amdgpu/amdgpu_drv.c, and these are all the sibling pages in the squad. no skipping, bestie — every single one is here:
