I did however also skip over the fact that GPUs with a GMU don't specify a core clock of any kind in the GPU node. While that didn't break anything, it did introduce unwanted spam in the dmesg: adreno 5000000.gpu: error -ENOENT: _opp_set_clknames: Couldn't find clock with name: core_clk Guard the entire logic so that it's not used with GMU-equipped GPUs.

It's a (good) software representation of the GMU_CX and GMU_GX register spaces within the GPUSS that helps us programatically treat these de-facto GMU-less parts in a way that's very similar to their GMU-equipped cousins, massively saving up on code duplication. The "wrapper" register space was specifically designed to mimic the layout of a real GMU, though it rather obviously does not have the M3 core et al. GMU wrapper-equipped A6xx GPUs require clocks and clock-names to be specified under the GPU node, just like their older cousins. Account for that.

It's a (good) software representation of the GMU_CX and GMU_GX register spaces within the GPUSS that helps us programatically treat these de-facto GMU-less parts in a way that's very similar to their GMU-equipped cousins, massively saving up on code duplication. The "wrapper" register space was specifically designed to mimic the layout of a real GMU, though it rather obviously does not have the M3 core et al. To sum it all up, the GMU wrapper is essentially a register space within the GPU, which Linux sees as a dumbed-down regular GMU: there's no clocks, interrupts, multiple reg spaces, iommus and OPP. Document it.

This is due to the fact that the GMU directly pokes at RPMh. Sadly, this means we have to take care of enabling & scaling power rails, clocks and bandwidth ourselves. Reuse existing Adreno-common code and modify the deeply-GMU-infused A6XX code to facilitate these GPUs. This involves if-ing out lots of GMU callbacks and introducing a new type of GMU - GMU wrapper (it's the actual name that Qualcomm uses in their downstream kernels). This is essentially a register region which is convenient to model as a device. We'll use it for managing the GDSCs. The register layout matches the actual GMU_CX/GX regions on the "real GMU" devices and lets us reuse quite a bit of gmu_read/write/rmw calls.

It features no GMU, as it's implemented solely on SoCs with SMD_RPM. What's more interesting is that it does not feature a VDDGX line either, being powered solely by VDDCX and has an unfortunate hardware quirk that makes its reset line broken - after a couple of assert/ deassert cycles, it will hang for good and will not wake up again. This GPU requires mesa changes for proper rendering, and lots of them at that. The command streams are quite far away from any other A6XX GPU and hence it needs special care. This patch was validated both by running an (incomplete) downstream mesa with some hacks (frames rendered correctly, though some instructions made the GPU hangcheck which is expected - garbage in, garbage out) and by replaying RD traces captured with the downstream KGSL driver - no crashes there, ever. Add support for this GPU on the kernel side, which comes down to pretty simply adding A612 HWCG tables, altering a few values and adding a special case for handling the reset line.
