Subject: [PATCH] arm-bsp/fvp-base: improve FVP performance
Date: Mon, 15 Apr 2024 15:07:35 +0000 [thread overview]
Message-ID: <20240415150735.3443599-1-ross.burton@arm.com> (raw)
Increase the number of TLB entries from 0x80 to 0x400 and disable the
checking of memory attributes. In our CI, this makes testimage run in
576s instead of 803s.
