STMicroelectonics Multi-Function eXpander (STMFX) Core bindings
|
||||
|
||||
ST Multi-Function eXpander (STMFX) is a slave controller using I2C for
|
||||
communication with the main MCU. Its main features are GPIO expansion, main
|
||||
MCU IDD measurement (IDD is the amount of current that flows through VDD) and
|
||||
resistive touchscreen controller.
|
||||
|
||||
Required properties:
|
||||
- compatible: should be "st,stmfx-0300".
|
||||
- reg: I2C slave address of the device.
|
||||
- interrupts: interrupt specifier triggered by MFX_IRQ_OUT signal.
|
||||
Please refer to ../interrupt-controller/interrupt.txt
|
||||
|
||||
Optional properties:
|
||||
- drive-open-drain: configure MFX_IRQ_OUT as open drain.
|
||||
- vdd-supply: phandle of the regulator supplying STMFX.
|
||||
|
||||
Example:
|
||||
|

|
||||
cell is the gpio flags in accordance with <dt-bindings/gpio/gpio.h>.
|
||||
- gpio-controller: marks the device as a GPIO controller.
|
||||
- #interrupt-cells: should be <2>, the first cell is the GPIO number and the
|
||||
second cell is the interrupt flags in accordance with
|
||||
<dt-bindings/interrupt-controller/irq.h>.
|
||||
- interrupt-controller: marks the device as an interrupt controller.
|
||||
- gpio-ranges: specifies the mapping between gpio controller and pin
|
||||
controller pins. Check "Concerning gpio-ranges property" below.
|
||||
Please refer to ../gpio/gpio.txt.
|
||||
|
||||
Please refer to pinctrl-bindings.txt for pin configuration.
|
||||
|
||||
Required properties for pin configuration sub-nodes:
|
||||
- pins: list of pins to which the configuration applies.
|
||||
|
||||
Optional properties for pin configuration sub-nodes (pinconf-generic ones):
|
||||
- bias-disable: disable any bias on the pin.
|
||||
- bias-pull-up: the pin will be pulled up.
|
||||
- bias-pull-pin-default: use the pin-default pull state.

|
||||
- drive-open-drain: the pin will be driven with open drain.
|
||||

|
||||
- output-low: the pin will be configured as an output driving low level.
|
||||
|
||||
Note that STMFX pins[15:0] are called "gpio[15:0]", and STMFX pins[23:16] are
|
||||
called "agpio[7:0]". Example, to refer to pin 18 of STMFX, use "agpio2".
|
||||
|
||||
Concerning gpio-ranges property:
|
||||
- if all STMFX pins[24:0] are available (no other STMFX function in use), you
|
||||
should use gpio-ranges = <&stmfx_pinctrl 0 0 24>;
|
||||
- if agpio[3:0] are not available (STMFX Touchscreen function in use), you
|
||||
should use gpio-ranges = <&stmfx_pinctrl 0 0 16>, <&stmfx_pinctrl 20 20 4>;
|
||||
- if agpio[7:4] are not available (STMFX IDD function in use), you
|
||||
should use gpio-ranges = <&stmfx_pinctrl 0 0 20>;

SUPERBLOCK CREATION HELPERS
|
||||
===========================
|
||||
|
||||
A number of VFS helpers are available for use by filesystems for the creation
|
||||
or looking up of superblocks.
|
||||
|
||||
(*) struct super_block *
|
||||
sget_fc(struct fs_context *fc,
|
||||
int (*test)(struct super_block *sb, struct fs_context *fc),
|
||||
int (*set)(struct super_block *sb, struct fs_context *fc));
|
||||
|
||||
This is the core routine. If test is non-NULL, it searches for an
|
||||
existing superblock matching the criteria held in the fs_context, using
|
||||
the test function to match them. If no match is found, a new superblock
|
||||
is created and the set function is called to set it up.
|
||||
|
||||
Prior to the set function being called, fc->s_fs_info will be transferred
|
||||
to sb->s_fs_info - and fc->s_fs_info will be cleared if set returns
|
||||
success (ie. 0).
|
||||
|
||||
The following helpers all wrap sget_fc():
|
||||
|
||||
(*) int vfs_get_super(struct fs_context *fc,
|
||||
enum vfs_get_super_keying keying,
|
||||
int (*fill_super)(struct super_block *sb,
|
||||
struct fs_context *fc))
|
||||
|
||||
This creates/looks up a deviceless superblock. The keying indicates how
|
||||
many superblocks of this type may exist and in what manner they may be
|
||||
shared:
|
||||
|
||||
(1) vfs_get_single_super
|
||||
|
||||
Only one such superblock may exist in the system. Any further
|
||||
attempt to get a new superblock gets this one (and any parameter
|
||||
differences are ignored).
|
||||
|
||||
(2) vfs_get_keyed_super
|
||||
|
||||
Multiple superblocks of this type may exist and they're keyed on
|
||||
their s_fs_info pointer (for example this may refer to a
|
||||
namespace).
|
||||
|
||||
(3) vfs_get_independent_super
|
||||
|
||||
Multiple independent superblocks of this type may exist. This
|
||||
function never matches an existing one and always creates a new
|
||||
one.

BPF Flow Dissector
|
||||
==================
|
||||
|
||||
Overview
|
||||
========
|
||||
|
||||
Flow dissector is a routine that parses metadata out of the packets. It's
|
||||
used in the various places in the networking subsystem (RFS, flow hash, etc).
|
||||
|
||||
BPF flow dissector is an attempt to reimplement C-based flow dissector logic
|
||||
in BPF to gain all the benefits of BPF verifier (namely, limits on the
|
||||
number of instructions and tail calls).
|
||||
|
||||
API
|
||||
===
|
||||
|
||||
BPF flow dissector programs operate on an ``__sk_buff``. However, only the
|
||||
limited set of fields is allowed: ``data``, ``data_end`` and ``flow_keys``.
|
||||
``flow_keys`` is ``struct bpf_flow_keys`` and contains flow dissector input
|
||||
and output arguments.
|
||||
|
||||
The inputs are:
|
||||
* ``nhoff`` - initial offset of the networking header
|
||||
* ``thoff`` - initial offset of the transport header, initialized to nhoff
|
||||
* ``n_proto`` - L3 protocol type, parsed out of L2 header
|
||||
|
||||
Flow dissector BPF program should fill out the rest of the ``struct
|
||||
bpf_flow_keys`` fields. Input arguments ``nhoff/thoff/n_proto`` should be
|
||||
also adjusted accordingly.
|
||||
|
||||
The return code of the BPF program is either BPF_OK to indicate successful
|
||||
dissection, or BPF_DROP to indicate parsing error.
|
||||
|
||||
__sk_buff->data
|
||||
===============
|
||||
|
||||
In the VLAN-less case, this is what the initial state of the BPF flow
|
||||
dissector looks like::
|
||||
|
||||
+------+------+------------+-----------+
|
||||
| DMAC | SMAC | ETHER_TYPE | L3_HEADER |
|
||||
+------+------+------------+-----------+
|
||||
^
|
||||
|
|
||||
+-- flow dissector starts here
|
||||
|
||||
|
||||
.. code:: c
|
||||
|
||||
skb->data + flow_keys->nhoff point to the first byte of L3_HEADER
|
||||
flow_keys->thoff = nhoff
|
||||
flow_keys->n_proto = ETHER_TYPE
|
||||
|
||||
In case of VLAN, flow dissector can be called with the two different states.
|
||||
|
||||
Pre-VLAN parsing::
|
||||
|
||||
+------+------+------+-----+-----------+-----------+
|
||||
| DMAC | SMAC | TPID | TCI |ETHER_TYPE | L3_HEADER |
|
||||
+------+------+------+-----+-----------+-----------+
|
||||
^
|
||||
|
|
||||
+-- flow dissector starts here
|
||||
|
||||
.. code:: c
|
||||
|
||||
skb->data + flow_keys->nhoff point the to first byte of TCI
|
||||
flow_keys->thoff = nhoff
|
||||
flow_keys->n_proto = TPID
|
||||
|
||||
Please note that TPID can be 802.1AD and, hence, BPF program would
|
||||
have to parse VLAN information twice for double tagged packets.
|
||||
|
||||
|
||||
Post-VLAN parsing::
|
||||
|
||||
+------+------+------+-----+-----------+-----------+
|
||||
| DMAC | SMAC | TPID | TCI |ETHER_TYPE | L3_HEADER |
|
||||
+------+------+------+-----+-----------+-----------+
|
||||
^
|
||||
|
|
||||
+-- flow dissector starts here
|
||||
|
||||
.. code:: c
|
||||
|
||||
skb->data + flow_keys->nhoff point the to first byte of L3_HEADER
|
||||
flow_keys->thoff = nhoff
|
||||
flow_keys->n_proto = ETHER_TYPE
|
||||
|
||||
In this case VLAN information has been processed before the flow dissector
|
||||
and BPF flow dissector is not required to handle it.
|
||||
|
||||
|
||||
The takeaway here is as follows: BPF flow dissector program can be called with
|
||||
the optional VLAN header and should gracefully handle both cases: when single
|
||||
or double VLAN is present and when it is not present. The same program
|
||||
can be called for both cases and would have to be written carefully to
|
||||
handle both cases.
|
||||
|
||||
|
||||
Reference Implementation
|
||||
========================
|
||||
|
||||
See ``tools/testing/selftests/bpf/progs/bpf_flow.c`` for the reference
|
||||
implementation and ``tools/testing/selftests/bpf/flow_dissector_load.[hc]``
|
||||
for the loader. bpftool can be used to load BPF flow dissector program as well.
|
||||
|
||||
The reference implementation is organized as follows:
|
||||
* ``jmp_table`` map that contains sub-programs for each supported L3 protocol
|
||||
* ``_dissect`` routine - entry point; it does input ``n_proto`` parsing and
|
||||
does ``bpf_tail_call`` to the appropriate L3 handler
|
||||
|
||||
Since BPF at this point doesn't support looping (or any jumping back),
|
||||
jmp_table is used instead to handle multiple levels of encapsulation (and
|
||||
IPv6 options).
|
||||
|
||||
|
||||
Current Limitations
|
||||
===================
|
||||
BPF flow dissector doesn't support exporting all the metadata that in-kernel
|
||||
C-based implementation can export. Notable example is single VLAN (802.1Q)
|
||||
and double VLAN (802.1AD) tags. Please refer to the ``struct bpf_flow_keys``
|
||||
for a set of information that's currently can be exported from the BPF context.

It is important to note that althought VM ioctls may only be issued from

the process that created the VM, a VM's lifecycle is associated with its

file descriptor, not its creator (process). In other words, the VM and
|

its resources, *including the associated address space*, are not freed
|

until the last reference to the VM's file descriptor has been released.

For example, if fork() is issued after ioctl(KVM_CREATE_VM), the VM will

not be freed until both the parent (original) process and its child have

put their references to the VM's file descriptor.

Because a VM's resources are not freed until the last reference to its

file descriptor is released, creating additional references to a VM via

via fork(), dup(), etc... without careful consideration is strongly
|

discouraged and may have unwanted side effects, e.g. memory allocated

by and on behalf of the VM's process may not be freed/unaccounted when

the VM is shut down.
