Subject: [PATCH 0/3] drm/msm/adreno: Support for CLX feature on A8xx
Date: Sat, 16 May 2026 01:37:48 +0530 [thread overview]
Message-ID: <20260516-a8xx-clx-support-v1-0-62508bf651ac@oss.qualcomm.com> (raw)
Add support for Current Limit Extension (CLX) feature found on a few A8x
GPUs. This feature is required to limit the peak current consumption to
avoid HW spec violation on GX/MX rails.
Add the necessary HFI interface support to pass the recommended CLX and
IFF/PCLX limits tables to the GMU. And enable this feature on both A840
and X285 GPU by adding the repective configurations to the gpu catalog.
