Subject: [PATCH v8 bpf-next 1/9] x86/Kconfig: select HAVE_ARCH_HUGE_VMALLOC with HAVE_ARCH_HUGE_VMAP
Date: Mon, 31 Jan 2022 22:27:55 -0800 [thread overview]
Message-ID: <20220201062803.2675204-2-song@kernel.org> (raw)
In-Reply-To: <20220201062803.2675204-1-song@kernel.org>
From: Song Liu <songliubraving@fb.com>
This enables module_alloc() to allocate huge page for 2MB+ requests.
To check the difference of this change, we need enable config
CONFIG_PTDUMP_DEBUGFS, and call module_alloc(2MB). Before the change,
/sys/kernel/debug/page_tables/kernel shows pte for this map. With the
change, /sys/kernel/debug/page_tables/ show pmd for thie map.
