Subject: [PATCH] riscv: increase COMMAND_LINE_SIZE value to 2048
Date: Mon, 19 Jan 2026 16:41:10 +0900 [thread overview]
Message-ID: <aW3gFmOlA/Z4kmfJ@adminpc-PowerEdge-R7525> (raw)
From: Austin Kim <austin.kim@lge.com>
SoC people may send many parameters to configure the drivers via kernel
command line. If COMMAND_LINE_SIZE is not enough, they may go through
unexpected error.
To avoid the potential pain, we had better increase COMMAND_LINE_SIZE.
