It doesn't kill anything, just tries to invalidate and if that doesn't work migrate the page away. This is useful for predictive failure analysis, where a page has a high rate of corrected errors, but hasn't gone bad yet. Instead it can be offlined early and avoided. The offlining is controlled from sysfs, including a new generic entry point for hard page offlining for symmetry too. We use the page isolate facility to prevent re-allocation race. Normally this is only used by memory hotplug. To avoid races with memory allocation I am using lock_system_sleep(). This avoids the situation where memory hotplug is about to isolate a page range and then hwpoison undoes that work. This is a big hammer currently, but the simplest solution currently. When the page is not free or LRU we try to free pages from slab and other caches. The slab freeing is currently quite dumb and does not try to focus on the specific slab cache which might own the page. This could be potentially improved later. Thanks to Fengguang Wu and Haicheng Li for some fixes. [Added fix from Andrew Morton to adapt to new migrate_pages prototype] Signed-off-by: Andi Kleen <ak@linux.intel.com>

(But it's OK to mis-hwpoison free/unowned pages as well as shared clean pages. Mis-hwpoison of shared dirty pages will kill all tasks, so the test suite will target all or non of such tasks in the first place.) The memory cgroup serves this purpose well. We can put the target processes under the control of a memory cgroup, and tell the hwpoison injection code to only kill pages associated with some active memory cgroup. The prerequisite for doing hwpoison stress tests with mem_cgroup is, the mem_cgroup code tracks task pages _accurately_ (unless page is locked). Which we believe is/should be true. The benefits are simplification of hwpoison injector code. Also the mem_cgroup code will automatically be tested by hwpoison test cases. The alternative interfaces pin-pfn/unpin-pfn can also delegate the (process and page flags) filtering functions reliably to user space. However prototype implementation shows that this scheme adds more complexity than we wanted. Example test case: mkdir /cgroup/hwpoison usemem -m 100 -s 1000 & echo `jobs -p` > /cgroup/hwpoison/tasks memcg_ino=$(ls -id /cgroup/hwpoison | cut -f1 -d' ') echo $memcg_ino > /debug/hwpoison/corrupt-filter-memcg page-types -p `pidof init` --hwpoison # shall do nothing page-types -p `pidof usemem` --hwpoison # poison its pages [AK: Fix documentation] [Add fix for problem noticed by Li Zefan <lizf@cn.fujitsu.com>; dentry in the css could be NULL] CC: KOSAKI Motohiro <kosaki.motohiro@jp.fujitsu.com> CC: Hugh Dickins <hugh.dickins@tiscali.co.uk> CC: Daisuke Nishimura <nishimura@mxp.nes.nec.co.jp> CC: Balbir Singh <balbir@linux.vnet.ibm.com> CC: KAMEZAWA Hiroyuki <kamezawa.hiroyu@jp.fujitsu.com> CC: Li Zefan <lizf@cn.fujitsu.com> CC: Paul Menage <menage@google.com> CC: Nick Piggin <npiggin@suse.de> CC: Andi Kleen <andi@firstfloor.org> Signed-off-by: Wu Fengguang <fengguang.wu@intel.com> Signed-off-by: Andi Kleen <ak@linux.intel.com>

However we can just do nothing because we set PG_locked in the beginning, this prevents the page allocator from allocating it to someone. (It will BUG() on the unexpected PG_locked, which is fine for hwpoison testing.)

This also avoids the very noisy "Injecting memory failure..." messages. - we don't touch madvise() based injection, because the filters are generally not necessary for it. - if we want to apply the filters to h/w aided injection, we'd better to rearrange the logic in __memory_failure() instead of this patch.

It can be enabled at module load time by a module parameter (volume_control=1). The audio control mixer that thinkpad-acpi interacts with is fully functional without any drivers, and operated by hotkeys. The idea behind the console audio control is that the human operator is the only one that can interact with it. The ThinkVantage suite in Windows does not allow any software-based overrides, and only does OSD (on-screen-display) functions. The Linux driver will, with the addition of the ALSA interface, try to follow and enforce the ThinkVantage UI design: The user is supposed to use the keyboard hotkeys to interact with the console audio control. The kernel and the desktop environment is supposed to cooperate to provide proper user feedback through on-screen-display functions. Distros are urged to not to enable volume control by default. Enabling this must be a local admin's decision. This is the reason why there is no Kconfig option. Keep in mind that all ThinkPads have a normal, main mixer (AC97 or HDA) for regular software-based audio control. We are not talking about that mixer here. Advanced users are, of course, free to enable volume control and do as they please.

Newer Lenovo models only have the mute gate function, and leave the volume control to the HDA mixer. Until a way to automatically query the firmware about its audio control capabilities is discovered (there might not be any), use a white/black list. We will likely need to ask T60 (old and new model) and Z60/Z61 users whether they have volume control to populate the black/white list. Meanwhile, provide a volume_capabilities parameter that can be used to override the defaults.

Change the driver to stop issuing SMIs, and just drive the EC directly to the desired level (DSDTs seem to confirm this will work even on very old models like the 570 and 600e/x). We checkpoint directly to NVRAM (this can be turned off) at suspend/shutdown/driver unload, which from what I can see in tbp, should also work on every ThinkPad.
