From 5c8de1bcfb0024993d902fb5dcfe87546116799b Mon Sep 17 00:00:00 2001 From: Heinrich Schuchardt Date: Sun, 8 Jun 2025 09:54:27 +0200 Subject: sandbox: align LMB memory To implement the EFI_SYSTEM_TABLE_POINTER we need 4 MiB aligned memory. On the sandbox LMB uses addresses relative to the start of a page aligned RAM buffer allocated with mmap(). This leads to a mismatch of alignment between EFI which uses pointers and LMB which uses phys_addr_t. Ensure that the RAM buffer used for LMB is 4 MiB aligned.
