From: Rob Clark <[email protected]>
Downstream seems to be moving to using the chip_id as simply an opaque
identifier, and if we want to avoid headaches with userspace mesa
supporting both kgsl and upstream, we should move away from the
assumption that certain bits in the chip_id have a specific meaning.
v2 adds a patch to move adreno_info to adreno_platform_config rather
than needing to look it up in multiple places.
Rob Clark (13):
drm/msm/adreno: Remove GPU name
drm/msm/adreno: Remove redundant gmem size param
drm/msm/adreno: Remove redundant revn param
drm/msm/adreno: Use quirk identify hw_apriv
drm/msm/adreno: Use quirk to identify cached-coherent support
drm/msm/adreno: Allow SoC specific gpu device table entries
drm/msm/adreno: Move speedbin mapping to device table
drm/msm/adreno: Bring the a630 family together
drm/msm/adreno: Add adreno family
drm/msm/adreno: Add helper for formating chip-id
drm/msm/adreno: Move adreno info to config
dt-bindings: drm/msm/gpu: Extend bindings for chip-id
drm/msm/adreno: Switch to chip-id for identifying GPU

Even in the ocmem case, the allocated ocmem buffer size should match the
requested size.
v2: Move stray hunk to previous patch, make OCMEM size mismatch an error
condition.

It is better to explicitly list it. With the move to opaque chip-id's
for future devices, we should avoid trying to infer things like
generation from the numerical value.

This means that we need to explicitly list different patch revisions in
the device table.

This leaves me with the feeling that we are abusing the
dev->platform_data, but we were doing it anyway even before the patch.

Anyway, I think we should insist here of using something human-readable,
even if Qualcomm/Adreno internally use some weird numbers.

We'll know when we bring up the hw. But the main point is that we
shouldn't expect, for example, the high 8 bits to tell us the
generation, any more than we could if it was a pci id.
We may not end up needing to use this new binding much, I _think_ we
should be able to read it from the fw in most cases, at least for
android devices. I'm unsure at this point about windows/chromebooks.

I mean qcom,sc8280cx-adreno is human readable but not really very
informative. Encoding the chip-id is just a way to avoid the
qcom,chipid field in the bindings, which qcom used downstream. The
new pattern accomplishes the same thing as the existing one, but
without trying to imply some meaning that becomes increasingly
non-existent as qc moves to decouple the id from marketing names.
