Subject: [Qemu-devel] [PATCH 03/13] oslib-posix: Align to permit transparent hugepages on ARM Linux
Date: Tue, 5 Mar 2013 01:12:01 +0000 [thread overview]
Message-ID: <1362445931-4383-4-git-send-email-peter.maydell@linaro.org> (raw)
In-Reply-To: <1362445931-4383-1-git-send-email-peter.maydell@linaro.org>
ARM Linux (like x86-64 Linux) can use transparent hugepages for
KVM if memory blocks are 2MiB aligned; set QEMU_VMALLOC_ALIGN
accordingly.
Signed-off-by: Peter Maydell <peter.maydell@linaro.org>

/* Use 2 MiB alignment so transparent hugepages can be used by KVM.
Valgrind does not support alignments larger than 1 MiB,
therefore we need special code which handles running on Valgrind. */
