From e889a311f74f4ae8bd40755a2c58d02e1c684fef Mon Sep 17 00:00:00 2001 From: Johnny Liu Date: Fri, 1 Sep 2023 14:59:09 +0300 Subject: [PATCH] gpu: host1x: Correct allocated size for contexts Original implementation over allocates the memory size for the contexts list. The size of memory for the contexts list is based on the number of iommu groups specified in the device tree.
