2025-11-18drm/msm/adreno: Introduce A8x GPU SupportAkhil P Oommen
A8x is the next generation of Adreno GPUs, featuring a significant hardware design change. A major update to the design is the introduction of Slice architecture. Slices are sort of mini-GPUs within the GPU which are more independent in processing Graphics and compute workloads. Also, in addition to the BV and BR pipe we saw in A7x, CP has more concurrency with additional pipes. From a software interface perspective, these changes have a significant impact on the KMD side. First, the GPU register space has been extensively reorganized. Second, to avoid a register space explosion caused by the new slice architecture and additional pipes, many registers are now virtualized, instead of duplicated as in A7x. KMD must configure an aperture register with the appropriate slice and pipe ID before accessing these virtualized registers.

2025-11-18drm/msm/a8xx: Add support for A8x GMUAkhil P Oommen
A8x GMU configurations are very similar to A7x. Unfortunately, there are minor shuffling in the register offsets in the GMU CX register region. So, update the driver to use the correct register offsets on A8x hw. Some A8x GPUs have more than 16 powerlevels on GX domain and 4 on CX domain. To accommodate this, increase the arrays' sizes which hold gx and cx power levels.

2025-11-18drm/msm/a6xx: Rebase GMU register offsetsAkhil P Oommen
GMU registers are always at a fixed offset from the GPU base address, a consistency maintained at least within a given architecture generation. In A8x family, the base address of the GMU has changed, but the offsets of the gmu registers remain largely the same. To enable reuse of the gmu code for A8x chipsets, update the gmu register offsets to be relative to the GPU's base address instead of GMU's.
