[edk2-devel] [PATCH v2] Platform/RaspberryPi: Only enable IORT when 3G limit is disabled.

2021-02-17 Thread jlinton
From: Jeremy Linton The 3G limit, and the 2G IORT are intended to solve the same linux problem. They limit PCI DMA operations to the first 3G of RAM. Older linux kernels, as used with RHEL/Centos, trigger an assertion* when a DMA operation starts at a range that doesn't fit within the 2G range
