From d44e0a892621a744e9a64e17ed5676470ef4f023 Mon Sep 17 00:00:00 2001 From: Wen Xiong Date: Mon, 20 Feb 2023 15:58:14 -0500 Subject: [PATCH 1/2] ieee1275: Further increase initially allocated heap from 1/3 to 1/2 The memory increase to 1/3 of 391MB (~127MB) was still insufficient to boot the kernel and initrd of the SuSE distribution: initrd 2023-Jan-18 04:27 114.9M linux 2023-Jan-17 05:23 45.9M Therefore, further increase the initially allocated heap to 1/2 of 391MB to ~191MB, which now allows to boot the system from an ISO.
