Subject: [PULL 5/6] target/mips: Support variable page size
Date: Mon, 1 Jun 2020 14:43:24 +0200 [thread overview]
Message-ID: <1591015405-19651-6-git-send-email-aleksandar.qemu.devel@gmail.com> (raw)
In-Reply-To: <1591015405-19651-1-git-send-email-aleksandar.qemu.devel@gmail.com>
From: Huacai Chen <chenhc@lemote.com>
Traditionally, MIPS use 4KB page size, but Loongson prefer 16KB page
size in system emulator. So, let's define TARGET_PAGE_BITS_VARY and
TARGET_PAGE_BITS_MIN to support variable page size.
