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.

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
to ensure that all elements are zeroed.
adjacent elements. Flexible array elements are normally initialized to the
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:
void flex_array_free_parts(struct flex_array *array);

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.
