What: Support for VMware's guest paravirtuliazation technique [VMI] will be
dropped.
When: 2.6.37 or earlier.
Why: With the recent innovations in CPU hardware acceleration technologies
from Intel and AMD, VMware ran a few experiments to compare these
techniques to guest paravirtualization technique on VMware's platform.
These hardware assisted virtualization techniques have outperformed the
performance benefits provided by VMI in most of the workloads. VMware
expects that these hardware features will be ubiquitous in a couple of
years, as a result, VMware has started a phased retirement of this
feature from the hypervisor. We will be removing this feature from the
Kernel too. Right now we are targeting 2.6.37 but can retire earlier if
technical reasons (read opportunity to remove major chunk of pvops)
arise.
Please note that VMI has always been an optimization and non-VMI kernels
still work fine on VMware's platform.
Latest versions of VMware's product which support VMI are,
Workstation 7.0 and VSphere 4.0 on ESX side, future maintainence
releases for these products will continue supporting VMI.
For more details about VMI retirement take a look at this,

When releasepage() is being implemented, a special FS-Cache function exists to

conflict with the cache trying to write pages to the cache (which may itself
need to allocate memory):
bool fscache_maybe_release_page(struct fscache_cookie *cookie,

This takes the netfs cookie, and the page and gfp arguments as supplied to
releasepage(). It will return false if the page cannot be released yet for
some reason and if it returns true, the page has been uncached and can now be
released.
To make a page available for release, this function may wait for an outstanding
storage request to complete, or it may attempt to cancel the storage request -
in which case the page will not be stored in the cache this time.

Note that it is possible to get back a valid pointer for an element which
has never been stored in the array. Memory for array elements is allocated
one page at a time; a single allocation could provide memory for several
adjacent elements. The flexible array code does not know if a specific
element has been written; it only knows if the associated memory is
present. So a flex_array_get() call on an element which was never stored
in the array has the potential to return a pointer to random data. If the
caller does not have a separate way to know which elements were actually
stored, it might be wise, at least, to add GFP_ZERO to the flags argument

value FLEX_ARRAY_FREE (defined as 0x6c in <linux/poison.h>), so errors
involving that number probably result from use of unstored array entries.
Note that, if array elements are allocated with __GFP_ZERO, they will be
initialized to zero and this poisoning will not happen.
There is no way to remove a single element from the array. It is possible,
though, to remove all elements with a call to:
Individual elements in the array can be cleared with:
int flex_array_clear(struct flex_array *array, unsigned int element_nr);
This function will set the given element to FLEX_ARRAY_FREE and return
zero. If storage for the indicated element is not allocated for the array,
flex_array_clear() will return -EINVAL instead. Note that clearing an
element does not release the storage associated with it; to reduce the
allocated size of an array, call:
int flex_array_shrink(struct flex_array *array);
The return value will be the number of pages of memory actually freed.
This function works by scanning the array for pages containing nothing but
FLEX_ARRAY_FREE bytes, so (1) it can be expensive, and (2) it will not work
if the array's pages are allocated with __GFP_ZERO.
It is possible to remove all elements of an array with a call to:

7. Debugging
The module kernelcapi has a module parameter showcapimsgs controlling some
debugging output produced by the module. It can only be set when the module is
loaded, via a parameter "showcapimsgs=<n>" to the modprobe command, either on
the command line or in the configuration file.
If the lowest bit of showcapimsgs is set, kernelcapi logs controller and
application up and down events.
In addition, every registered CAPI controller has an associated traceflag
parameter controlling how CAPI messages sent from and to tha controller are
logged. The traceflag parameter is initialized with the value of the
showcapimsgs parameter when the controller is registered, but can later be
changed via the MANUFACTURER_REQ command KCAPI_CMD_TRACE.
If the value of traceflag is non-zero, CAPI messages are logged.
DATA_B3 messages are only logged if the value of traceflag is > 2.
If the lowest bit of traceflag is set, only the command/subcommand and message
length are logged. Otherwise, kernelcapi logs a readable representation of
the entire message.

================
HELPER FUNCTIONS
================
The slow-work facility provides a function by which it can be determined
whether or not an item is queued for later execution:
bool queued = slow_work_is_queued(struct slow_work *work);
If it returns false, then the item is not on the queue (it may be executing
with a requeue pending). This can be used to work out whether an item on which
another depends is on the queue, thus allowing a dependent item to be queued
after it.
If the above shows an item on which another depends not to be queued, then the
owner of the dependent item might need to wait. However, to avoid locking up
the threads unnecessarily be sleeping in them, it can make sense under some
circumstances to return the work item to the queue, thus deferring it until
some other items have had a chance to make use of the yielded thread.
To yield a thread and defer an item, the work function should simply enqueue
the work item again and return. However, this doesn't work if there's nothing
actually on the queue, as the thread just vacated will jump straight back into
the item's work function, thus busy waiting on a CPU.
Instead, the item should use the thread to wait for the dependency to go away,
but rather than using schedule() or schedule_timeout() to sleep, it should use
the following function:
bool requeue = slow_work_sleep_till_thread_needed(
struct slow_work *work,
signed long *_timeout);
This will add a second wait and then sleep, such that it will be woken up if
either something appears on the queue that could usefully make use of the
thread - and behind which this item can be queued, or if the event the caller
set up to wait for happens. True will be returned if something else appeared
on the queue and this work function should perhaps return, of false if
something else woke it up. The timeout is as for schedule_timeout().
For example:
wq = bit_waitqueue(&my_flags, MY_BIT);
init_wait(&wait);
requeue = false;
do {
prepare_to_wait(wq, &wait, TASK_UNINTERRUPTIBLE);
if (!test_bit(MY_BIT, &my_flags))
break;
requeue = slow_work_sleep_till_thread_needed(&my_work,
&timeout);
} while (timeout > 0 && !requeue);

What is hwpoison?
Upcoming Intel CPUs have support for recovering from some memory errors
(``MCA recovery''). This requires the OS to declare a page "poisoned",
kill the processes associated with it and avoid using it in the future.
This patchkit implements the necessary infrastructure in the VM.
To quote the overview comment:
* High level machine check handler. Handles pages reported by the
* hardware as being corrupted usually due to a 2bit ECC memory or cache
* failure.
*
* This focusses on pages detected as corrupted in the background.
* When the current CPU tries to consume corruption the currently
* running process can just be killed directly instead. This implies
* that if the error cannot be handled for some reason it's safe to
* just ignore it because no corruption has been consumed yet. Instead
* when that happens another machine check will happen.
*
* Handles page cache pages in various states. The tricky part
* here is that we can access any page asynchronous to other VM
* users, because memory failures could happen anytime and anywhere,
* possibly violating some of their assumptions. This is why this code
* has to be extremely careful. Generally it tries to use normal locking
* rules, as in get the standard locks, even if that means the
* error handling takes potentially a long time.
*
* Some of the operations here are somewhat inefficient and have non
* linear algorithmic complexity, because the data structures have not
* been optimized for this case. This is in particular the case
* for the mapping from a vma to a process. Since this case is expected
* to be rare we hope we can get away with this.
The code consists of a the high level handler in mm/memory-failure.c,
a new page poison bit and various checks in the VM to handle poisoned
pages.
The main target right now is KVM guests, but it works for all kinds
of applications. KVM support requires a recent qemu-kvm release.
For the KVM use there was need for a new signal type so that
KVM can inject the machine check into the guest with the proper
address. This in theory allows other applications to handle
memory failures too. The expection is that near all applications
won't do that, but some very specialized ones might.
---
There are two (actually three) modi memory failure recovery can be in:
vm.memory_failure_recovery sysctl set to zero:
All memory failures cause a panic. Do not attempt recovery.
(on x86 this can be also affected by the tolerant level of the
MCE subsystem)
early kill
(can be controlled globally and per process)
Send SIGBUS to the application as soon as the error is detected
This allows applications who can process memory errors in a gentle
way (e.g. drop affected object)
This is the mode used by KVM qemu.
late kill
Send SIGBUS when the application runs into the corrupted page.
This is best for memory error unaware applications and default
Note some pages are always handled as late kill.
---
User control:
vm.memory_failure_recovery
See sysctl.txt
vm.memory_failure_early_kill
Enable early kill mode globally
PR_MCE_KILL
Set early/late kill mode/revert to system default
arg1: PR_MCE_KILL_CLEAR: Revert to system default
arg1: PR_MCE_KILL_SET: arg2 defines thread specific mode
