This binding is a work-in-progress, and are based on some experimental
work by benh[1].
Sources of clock signal can be represented by any node in the device
tree. Those nodes are designated as clock providers. Clock consumer
nodes use a phandle and clock specifier pair to connect clock provider
outputs to clock inputs. Similar to the gpio specifiers, a clock
specifier is an array of one more more cells identifying the clock
output on a device. The length of a clock specifier is defined by the
value of a #clock-cells property in the clock provider node.
[1] http://patchwork.ozlabs.org/patch/31551/
==Clock providers==
Required properties:
#clock-cells: Number of cells in a clock specifier; Typically 0 for nodes
with a single clock output and 1 for nodes with multiple
clock outputs.
Optional properties:
clock-output-names: Recommended to be a list of strings of clock output signal
names indexed by the first cell in the clock specifier.
However, the meaning of clock-output-names is domain
specific to the clock provider, and is only provided to
encourage using the same meaning for the majority of clock
providers. This format may not work for clock providers
using a complex clock specifier format. In those cases it
is recommended to omit this property and create a binding
specific names property.
Clock consumer nodes must never directly reference
the provider's clock-output-names property.
For example:
oscillator {
#clock-cells = <1>;
clock-output-names = "ckil", "ckih";
};
- this node defines a device with two clock outputs, the first named
"ckil" and the second named "ckih". Consumer nodes always reference
clocks by index. The names should reflect the clock output signal
names for the device.
==Clock consumers==
Required properties:
clocks: List of phandle and clock specifier pairs, one pair
for each clock input to the device. Note: if the
clock provider specifies '0' for #clock-cells, then
only the phandle portion of the pair will appear.
Optional properties:
clock-names: List of clock input name strings sorted in the same
order as the clocks property. Consumers drivers
will use clock-names to match clock input names
with clocks specifiers.
clock-ranges: Empty property indicating that child nodes can inherit named
clocks from this node. Useful for bus nodes to provide a
clock to their children.
For example:
device {
clocks = <&osc 1>, <&ref 0>;
clock-names = "baud", "register";
};
This represents a device with two clock inputs, named "baud" and "register".
The baud clock is connected to output 1 of the &osc device, and the register
clock is connected to output 0 of the &ref.
==Example==
/* external oscillator */
osc: oscillator {
compatible = "fixed-clock";
#clock-cells = <1>;
clock-frequency = <32678>;
clock-output-names = "osc";
};
/* phase-locked-loop device, generates a higher frequency clock
* from the external oscillator reference */
pll: pll@4c000 {
compatible = "vendor,some-pll-interface"
#clock-cells = <1>;
clocks = <&osc 0>;
clock-names = "ref";
reg = <0x4c000 0x1000>;
clock-output-names = "pll", "pll-switched";
};
/* UART, using the low frequency oscillator for the baud clock,
* and the high frequency switched PLL output for register
* clocking */
uart@a000 {
compatible = "fsl,imx-uart";
reg = <0xa000 0x1000>;
interrupts = <33>;
clocks = <&osc 0>, <&pll 1>;
clock-names = "baud", "register";
};
This DT fragment defines three devices: an external oscillator to provide a
low-frequency reference clock, a PLL device to generate a higher frequency
clock signal, and a UART.
* The oscillator is fixed-frequency, and provides one clock output, named "osc".
* The PLL is both a clock provider and a clock consumer. It uses the clock
signal generated by the external oscillator, and provides two output signals
("pll" and "pll-switched").
* The UART has its baud clock connected the external oscillator and its
register clock connected to the PLL clock (the "pll-switched" signal)

This driver assumes that there is only one register for each pin,
and uses the common pinctrl bindings as specified in the pinctrl-bindings.txt
document in this directory.
The pin configuration nodes for pinctrl-single are specified as pinctrl
register offset and value pairs using pinctrl-single,pins. Only the bits
specified in pinctrl-single,function-mask are updated. For example, setting
a pin for a device could be done with:
pinctrl-single,pins = <0xdc 0x118>;
Where 0xdc is the offset from the pinctrl register base address for the
device pinctrl register, and 0x118 contains the desired value of the
pinctrl register. See the device example and static board pins example
below for more information.

UHID - User-space I/O driver support for HID subsystem
========================================================
The HID subsystem needs two kinds of drivers. In this document we call them:
1. The "HID I/O Driver" is the driver that performs raw data I/O to the
low-level device. Internally, they register an hid_ll_driver structure with
the HID core. They perform device setup, read raw data from the device and
push it into the HID subsystem and they provide a callback so the HID
subsystem can send data to the device.
2. The "HID Device Driver" is the driver that parses HID reports and reacts on
them. There are generic drivers like "generic-usb" and "generic-bluetooth"
which adhere to the HID specification and provide the standardizes features.
But there may be special drivers and quirks for each non-standard device out
there. Internally, they use the hid_driver structure.
Historically, the USB stack was the first subsystem to provide an HID I/O
Driver. However, other standards like Bluetooth have adopted the HID specs and
may provide HID I/O Drivers, too. The UHID driver allows to implement HID I/O
Drivers in user-space and feed the data into the kernel HID-subsystem.
This allows user-space to operate on the same level as USB-HID, Bluetooth-HID
and similar. It does not provide a way to write HID Device Drivers, though. Use
hidraw for this purpose.
There is an example user-space application in ./samples/uhid/uhid-example.c
The UHID API
------------
UHID is accessed through a character misc-device. The minor-number is allocated
dynamically so you need to rely on udev (or similar) to create the device node.
This is /dev/uhid by default.
If a new device is detected by your HID I/O Driver and you want to register this
device with the HID subsystem, then you need to open /dev/uhid once for each
device you want to register. All further communication is done by read()'ing or
write()'ing "struct uhid_event" objects. Non-blocking operations are supported
by setting O_NONBLOCK.
struct uhid_event {
__u32 type;
union {
struct uhid_create_req create;
struct uhid_data_req data;
...
} u;
};
The "type" field contains the ID of the event. Depending on the ID different
payloads are sent. You must not split a single event across multiple read()'s or
multiple write()'s. A single event must always be sent as a whole. Furthermore,
only a single event can be sent per read() or write(). Pending data is ignored.
If you want to handle multiple events in a single syscall, then use vectored
I/O with readv()/writev().
The first thing you should do is sending an UHID_CREATE event. This will
register the device. UHID will respond with an UHID_START event. You can now
start sending data to and reading data from UHID. However, unless UHID sends the
UHID_OPEN event, the internally attached HID Device Driver has no user attached.
That is, you might put your device asleep unless you receive the UHID_OPEN
event. If you receive the UHID_OPEN event, you should start I/O. If the last
user closes the HID device, you will receive an UHID_CLOSE event. This may be
followed by an UHID_OPEN event again and so on. There is no need to perform
reference-counting in user-space. That is, you will never receive multiple
UHID_OPEN events without an UHID_CLOSE event. The HID subsystem performs
ref-counting for you.
You may decide to ignore UHID_OPEN/UHID_CLOSE, though. I/O is allowed even
though the device may have no users.
If you want to send data to the HID subsystem, you send an HID_INPUT event with
your raw data payload. If the kernel wants to send data to the device, you will
read an UHID_OUTPUT or UHID_OUTPUT_EV event.
If your device disconnects, you should send an UHID_DESTROY event. This will
unregister the device. You can now send UHID_CREATE again to register a new
device.
If you close() the fd, the device is automatically unregistered and destroyed
internally.
write()
-------
write() allows you to modify the state of the device and feed input data into
the kernel. The following types are supported: UHID_CREATE, UHID_DESTROY and
UHID_INPUT. The kernel will parse the event immediately and if the event ID is
not supported, it will return -EOPNOTSUPP. If the payload is invalid, then
-EINVAL is returned, otherwise, the amount of data that was read is returned and
the request was handled successfully.
UHID_CREATE:
This creates the internal HID device. No I/O is possible until you send this
event to the kernel. The payload is of type struct uhid_create_req and
contains information about your device. You can start I/O now.
UHID_DESTROY:
This destroys the internal HID device. No further I/O will be accepted. There
may still be pending messages that you can receive with read() but no further
UHID_INPUT events can be sent to the kernel.
You can create a new device by sending UHID_CREATE again. There is no need to
reopen the character device.
UHID_INPUT:
You must send UHID_CREATE before sending input to the kernel! This event
contains a data-payload. This is the raw data that you read from your device.
The kernel will parse the HID reports and react on it.
UHID_FEATURE_ANSWER:
If you receive a UHID_FEATURE request you must answer with this request. You
must copy the "id" field from the request into the answer. Set the "err" field
to 0 if no error occured or to EIO if an I/O error occurred.
If "err" is 0 then you should fill the buffer of the answer with the results
of the feature request and set "size" correspondingly.
read()
------
read() will return a queued ouput report. These output reports can be of type
UHID_START, UHID_STOP, UHID_OPEN, UHID_CLOSE, UHID_OUTPUT or UHID_OUTPUT_EV. No
reaction is required to any of them but you should handle them according to your
needs. Only UHID_OUTPUT and UHID_OUTPUT_EV have payloads.
UHID_START:
This is sent when the HID device is started. Consider this as an answer to
UHID_CREATE. This is always the first event that is sent.
UHID_STOP:
This is sent when the HID device is stopped. Consider this as an answer to
UHID_DESTROY.
If the kernel HID device driver closes the device manually (that is, you
didn't send UHID_DESTROY) then you should consider this device closed and send
an UHID_DESTROY event. You may want to reregister your device, though. This is
always the last message that is sent to you unless you reopen the device with
UHID_CREATE.
UHID_OPEN:
This is sent when the HID device is opened. That is, the data that the HID
device provides is read by some other process. You may ignore this event but
it is useful for power-management. As long as you haven't received this event
there is actually no other process that reads your data so there is no need to
send UHID_INPUT events to the kernel.
UHID_CLOSE:
This is sent when there are no more processes which read the HID data. It is
the counterpart of UHID_OPEN and you may as well ignore this event.
UHID_OUTPUT:
This is sent if the HID device driver wants to send raw data to the I/O
device. You should read the payload and forward it to the device. The payload
is of type "struct uhid_data_req".
This may be received even though you haven't received UHID_OPEN, yet.
UHID_OUTPUT_EV:
Same as UHID_OUTPUT but this contains a "struct input_event" as payload. This
is called for force-feedback, LED or similar events which are received through
an input device by the HID subsystem. You should convert this into raw reports
and send them to your device similar to events of type UHID_OUTPUT.
UHID_FEATURE:
This event is sent if the kernel driver wants to perform a feature request as
described in the HID specs. The report-type and report-number are available in
the payload.
The kernel serializes feature requests so there will never be two in parallel.
However, if you fail to respond with a UHID_FEATURE_ANSWER in a time-span of 5
seconds, then the requests will be dropped and a new one might be sent.
Therefore, the payload also contains an "id" field that identifies every
request.

Supported chips:
* Dialog Semiconductors DA9052-BC and DA9053-AA/Bx PMICs
Prefix: 'da9052'
Datasheet: Datasheet is not publicly available.
Authors: David Dajun Chen <dchen@diasemi.com>
Description
-----------
The DA9052/53 provides an Analogue to Digital Converter (ADC) with 10 bits
resolution and track and hold circuitry combined with an analogue input
multiplexer. The analogue input multiplexer will allow conversion of up to 10
different inputs. The track and hold circuit ensures stable input voltages at
the input of the ADC during the conversion.
The ADC is used to measure the following inputs:
Channel 0: VDDOUT - measurement of the system voltage
Channel 1: ICH - internal battery charger current measurement
Channel 2: TBAT - output from the battery NTC
Channel 3: VBAT - measurement of the battery voltage
Channel 4: ADC_IN4 - high impedance input (0 - 2.5V)
Channel 5: ADC_IN5 - high impedance input (0 - 2.5V)
Channel 6: ADC_IN6 - high impedance input (0 - 2.5V)
Channel 7: XY - TSI interface to measure the X and Y voltage of the touch
screen resistive potentiometers
Channel 8: Internal Tjunc. - sense (internal temp. sensor)
Channel 9: VBBAT - measurement of the backup battery voltage
By using sysfs attributes we can measure the system voltage VDDOUT, the battery
charging current ICH, battery temperature TBAT, battery junction temperature
TJUNC, battery voltage VBAT and the back up battery voltage VBBAT.
Voltage Monitoring
------------------
Voltages are sampled by a 10 bit ADC.
The battery voltage is calculated as:
Milli volt = ((ADC value * 1000) / 512) + 2500
The backup battery voltage is calculated as:
Milli volt = (ADC value * 2500) / 512;
The voltages on ADC channels 4, 5 and 6 are calculated as:
Milli volt = (ADC value * 2500) / 1023
Temperature Monitoring
----------------------
Temperatures are sampled by a 10 bit ADC. Junction and battery temperatures
are monitored by the ADC channels.
The junction temperature is calculated:
Degrees celsius = 1.708 * (TJUNC_RES - T_OFFSET) - 108.8
The junction temperature attribute is supported by the driver.
The battery temperature is calculated:
Degree Celcius = 1 / (t1 + 1/298)- 273
where t1 = (1/B)* ln(( ADCval * 2.5)/(R25*ITBAT*255))
Default values of R25, B, ITBAT are 10e3, 3380 and 50e-6 respectively.

Using the Kernel API
----------------------
The Kernel API is used for accessing CAIF channels from the
kernel.
The user of the API has to implement two callbacks for receive
and control.
The receive callback gives a CAIF packet as a SKB. The control
callback will
notify of channel initialization complete, and flow-on/flow-
off.
struct caif_device caif_dev = {
.caif_config = {
.name = "MYDEV"

.control_cb = my_control,
};

Remark about CAN FD (flexible data rate) support:
Generally the handling of CAN FD is very similar to the formerly described
examples. The new CAN FD capable CAN controllers support two different
bitrates for the arbitration phase and the payload phase of the CAN FD frame
and up to 64 bytes of payload. This extended payload length breaks all the
kernel interfaces (ABI) which heavily rely on the CAN frame with fixed eight
bytes of payload (struct can_frame) like the CAN_RAW socket. Therefore e.g.
the CAN_RAW socket supports a new socket option CAN_RAW_FD_FRAMES that
switches the socket into a mode that allows the handling of CAN FD frames
and (legacy) CAN frames simultaneously (see section 4.1.5).
The struct canfd_frame is defined in include/linux/can.h:
struct canfd_frame {
canid_t can_id; /* 32 bit CAN_ID + EFF/RTR/ERR flags */
__u8 len; /* frame payload length in byte (0 .. 64) */
__u8 flags; /* additional flags for CAN FD */
__u8 __res0; /* reserved / padding */
__u8 __res1; /* reserved / padding */
__u8 data[64] __attribute__((aligned(8)));
};
The struct canfd_frame and the existing struct can_frame have the can_id,
the payload length and the payload data at the same offset inside their
structures. This allows to handle the different structures very similar.
When the content of a struct can_frame is copied into a struct canfd_frame
all structure elements can be used as-is - only the data[] becomes extended.
When introducing the struct canfd_frame it turned out that the data length
code (DLC) of the struct can_frame was used as a length information as the
length and the DLC has a 1:1 mapping in the range of 0 .. 8. To preserve
the easy handling of the length information the canfd_frame.len element
contains a plain length value from 0 .. 64. So both canfd_frame.len and
can_frame.can_dlc are equal and contain a length information and no DLC.
For details about the distinction of CAN and CAN FD capable devices and
the mapping to the bus-relevant data length code (DLC), see chapter 6.6.
The length of the two CAN(FD) frame structures define the maximum transfer
unit (MTU) of the CAN(FD) network interface and skbuff data length. Two
definitions are specified for CAN specific MTUs in include/linux/can.h :
#define CAN_MTU (sizeof(struct can_frame)) == 16 => 'legacy' CAN frame
#define CANFD_MTU (sizeof(struct canfd_frame)) == 72 => CAN FD frame

4.1.5 RAW socket returned message flags
4.1.5 RAW socket option CAN_RAW_FD_FRAMES
CAN FD support in CAN_RAW sockets can be enabled with a new socket option
CAN_RAW_FD_FRAMES which is off by default. When the new socket option is
not supported by the CAN_RAW socket (e.g. on older kernels), switching the
CAN_RAW_FD_FRAMES option returns the error -ENOPROTOOPT.
Once CAN_RAW_FD_FRAMES is enabled the application can send both CAN frames
and CAN FD frames. OTOH the application has to handle CAN and CAN FD frames
when reading from the socket.
CAN_RAW_FD_FRAMES enabled: CAN_MTU and CANFD_MTU are allowed
CAN_RAW_FD_FRAMES disabled: only CAN_MTU is allowed (default)
Example:
[ remember: CANFD_MTU == sizeof(struct canfd_frame) ]
struct canfd_frame cfd;
nbytes = read(s, &cfd, CANFD_MTU);
if (nbytes == CANFD_MTU) {
printf("got CAN FD frame with length %d\n", cfd.len);
/* cfd.flags contains valid data */
} else if (nbytes == CAN_MTU) {
printf("got legacy CAN frame with length %d\n", cfd.len);
/* cfd.flags is undefined */
} else {
fprintf(stderr, "read: invalid CAN(FD) frame\n");
return 1;
}
/* the content can be handled independently from the received MTU size */
printf("can_id: %X data length: %d data: ", cfd.can_id, cfd.len);
for (i = 0; i < cfd.len; i++)
printf("%02X ", cfd.data[i]);
When reading with size CANFD_MTU only returns CAN_MTU bytes that have
been received from the socket a legacy CAN frame has been read into the
provided CAN FD structure. Note that the canfd_frame.flags data field is
not specified in the struct can_frame and therefore it is only valid in
CANFD_MTU sized CAN FD frames.
As long as the payload length is <=8 the received CAN frames from CAN FD
capable CAN devices can be received and read by legacy sockets too. When
user-generated CAN FD frames have a payload length <=8 these can be send
by legacy CAN network interfaces too. Sending CAN FD frames with payload
length > 8 to a legacy CAN network interface returns an -EMSGSIZE error.
Implementation hint for new CAN applications:
To build a CAN FD aware application use struct canfd_frame as basic CAN
data structure for CAN_RAW based applications. When the application is
executed on an older Linux kernel and switching the CAN_RAW_FD_FRAMES
socket option returns an error: No problem. You'll get legacy CAN frames
or CAN FD frames and can process them the same way.
When sending to CAN devices make sure that the device is capable to handle
CAN FD frames by checking if the device maximum transfer unit is CANFD_MTU.
The CAN device MTU can be retrieved e.g. with a SIOCGIFMTU ioctl() syscall.

6.6 Supported CAN hardware
6.6 CAN FD (flexible data rate) driver support
CAN FD capable CAN controllers support two different bitrates for the
arbitration phase and the payload phase of the CAN FD frame. Therefore a
second bittiming has to be specified in order to enable the CAN FD bitrate.
Additionally CAN FD capable CAN controllers support up to 64 bytes of
payload. The representation of this length in can_frame.can_dlc and
canfd_frame.len for userspace applications and inside the Linux network
layer is a plain value from 0 .. 64 instead of the CAN 'data length code'.
The data length code was a 1:1 mapping to the payload length in the legacy
CAN frames anyway. The payload length to the bus-relevant DLC mapping is
only performed inside the CAN drivers, preferably with the helper
functions can_dlc2len() and can_len2dlc().
The CAN netdevice driver capabilities can be distinguished by the network
devices maximum transfer unit (MTU):
MTU = 16 (CAN_MTU) => sizeof(struct can_frame) => 'legacy' CAN device
MTU = 72 (CANFD_MTU) => sizeof(struct canfd_frame) => CAN FD capable device
The CAN device MTU can be retrieved e.g. with a SIOCGIFMTU ioctl() syscall.
N.B. CAN FD capable devices can also handle and send legacy CAN frames.

disable some functionalities & save power during the period of low-link
utilization. The MAC controls whether the system should enter or exit
the LPI mode & communicate this to PHY.
As soon as the interface is opened, the driver verifies if the EEE can
be supported. This is done by looking at both the DMA HW capability

Typically, such an event will be propagated to NFC Core from MSGRXWQ context.
Error management
----------------
Errors that occur synchronously with the execution of an NFC Core request are
simply returned as the execution result of the request. These are easy.
Errors that occur asynchronously (e.g. in a background protocol handling thread)
must be reported such that upper layers don't stay ignorant that something
went wrong below and know that expected events will probably never happen.
Handling of these errors is done as follows:
- driver (pn544) fails to deliver an incoming frame: it stores the error such
that any subsequent call to the driver will result in this error. Then it calls
the standard nfc_shdlc_recv_frame() with a NULL argument to report the problem
above. shdlc stores a EREMOTEIO sticky status, which will trigger SMW to
report above in turn.
- SMW is basically a background thread to handle incoming and outgoing shdlc
frames. This thread will also check the shdlc sticky status and report to HCI
when it discovers it is not able to run anymore because of an unrecoverable
error that happened within shdlc or below. If the problem occurs during shdlc
connection, the error is reported through the connect completion.
- HCI: if an internal HCI error happens (frame is lost), or HCI is reported an
error from a lower layer, HCI will either complete the currently executing
command with that error, or notify NFC Core directly if no command is executing.
- NFC Core: when NFC Core is notified of an error from below and polling is
active, it will send a tag discovered event with an empty tag list to the user
space to let it know that the poll operation will never be able to detect a tag.
If polling is not active and the error was sticky, lower levels will return it
at next invocation.

Parameters: Pointer to u32 containing hash table order (in/out)
Returns: 0 on success, -1 on error
This requests the host kernel to allocate an MMU hash table for a
guest using the PAPR paravirtualization interface. This only does
anything if the kernel is configured to use the Book 3S HV style of
virtualization. Otherwise the capability doesn't exist and the ioctl
returns an ENOTTY error. The rest of this description assumes Book 3S
HV.
There must be no vcpus running when this ioctl is called; if there
are, it will do nothing and return an EBUSY error.
The parameter is a pointer to a 32-bit unsigned integer variable
containing the order (log base 2) of the desired size of the hash
table, which must be between 18 and 46. On successful return from the
ioctl, it will have been updated with the order of the hash table that
was allocated.
If no hash table has been allocated when any vcpu is asked to run
(with the KVM_RUN ioctl), the host kernel will allocate a
default-sized hash table (16 MB).
If this ioctl is called when a hash table has already been allocated,
the kernel will clear out the existing hash table (zero all HPTEs) and
return the hash table order in the parameter. (If the guest is using
the virtualized real-mode area (VRMA) facility, the kernel will
re-create the VMRA HPTEs on the next KVM_RUN of any vcpu.)

Fast page fault:
Fast page fault is the fast path which fixes the guest page fault out of
the mmu-lock on x86. Currently, the page fault can be fast only if the
shadow page table is present and it is caused by write-protect, that means
we just need change the W bit of the spte.
What we use to avoid all the race is the SPTE_HOST_WRITEABLE bit and
SPTE_MMU_WRITEABLE bit on the spte:
- SPTE_HOST_WRITEABLE means the gfn is writable on host.
- SPTE_MMU_WRITEABLE means the gfn is writable on mmu. The bit is set when
the gfn is writable on guest mmu and it is not write-protected by shadow
page write-protection.
On fast page fault path, we will use cmpxchg to atomically set the spte W
bit if spte.SPTE_HOST_WRITEABLE = 1 and spte.SPTE_WRITE_PROTECT = 1, this
is safe because whenever changing these bits can be detected by cmpxchg.
But we need carefully check these cases:
1): The mapping from gfn to pfn
The mapping from gfn to pfn may be changed since we can only ensure the pfn
is not changed during cmpxchg. This is a ABA problem, for example, below case
will happen:
At the beginning:
gpte = gfn1
gfn1 is mapped to pfn1 on host
spte is the shadow page table entry corresponding with gpte and
spte = pfn1
VCPU 0 VCPU0
on fast page fault path:
old_spte = *spte;
pfn1 is swapped out:
spte = 0;
pfn1 is re-alloced for gfn2.
gpte is changed to point to
gfn2 by the guest:
spte = pfn1;

We dirty-log for gfn1, that means gfn2 is lost in dirty-bitmap.
For direct sp, we can easily avoid it since the spte of direct sp is fixed
to gfn. For indirect sp, before we do cmpxchg, we call gfn_to_pfn_atomic()
to pin gfn to pfn, because after gfn_to_pfn_atomic():
- We have held the refcount of pfn that means the pfn can not be freed and
be reused for another gfn.
- The pfn is writable that means it can not be shared between different gfns
by KSM.
Then, we can ensure the dirty bitmaps is correctly set for a gfn.
Currently, to simplify the whole things, we disable fast page fault for
indirect shadow page.
2): Dirty bit tracking
In the origin code, the spte can be fast updated (non-atomically) if the
spte is read-only and the Accessed bit has already been set since the
Accessed bit and Dirty bit can not be lost.
But it is not true after fast page fault since the spte can be marked
writable between reading spte and updating spte. Like below case:
At the beginning:
spte.W = 0
spte.Accessed = 1
VCPU 0 VCPU0
In mmu_spte_clear_track_bits():
old_spte = *spte;
/* 'if' condition is satisfied. */
if (old_spte.Accssed == 1 &&
old_spte.W == 0)
spte = 0ull;
on fast page fault path:
spte.W = 1
memory write on the spte:
spte.Dirty = 1
else
old_spte = xchg(spte, 0ull)
if (old_spte.Accssed == 1)
kvm_set_pfn_accessed(spte.pfn);
if (old_spte.Dirty == 1)
kvm_set_pfn_dirty(spte.pfn);
OOPS!!!
The Dirty bit is lost in this case.
In order to avoid this kind of issue, we always treat the spte as "volatile"
if it can be updated out of mmu-lock, see spte_has_volatile_bits(), it means,
the spte is always atomicly updated in this case.
3): flush tlbs due to spte updated
If the spte is updated from writable to readonly, we should flush all TLBs,
otherwise rmap_write_protect will find a read-only spte, even though the
writable spte might be cached on a CPU's TLB.
As mentioned before, the spte can be updated to writable out of mmu-lock on
fast page fault path, in order to easily audit the path, we see if TLBs need
be flushed caused by this reason in mmu_spte_update() since this is a common
function to update spte (present -> present).
Since the spte is "volatile" if it can be updated out of mmu-lock, we always
atomicly update the spte, the race caused by fast page fault can be avoided,
See the comments in spte_has_volatile_bits() and mmu_spte_update().

steal: the amount of time in which this vCPU did not run, in
nanoseconds. Time during which the vcpu is idle, will not be
reported as steal time.
MSR_KVM_EOI_EN: 0x4b564d04
data: Bit 0 is 1 when PV end of interrupt is enabled on the vcpu; 0
when disabled. Bit 1 is reserved and must be zero. When PV end of
interrupt is enabled (bit 0 set), bits 63-2 hold a 4-byte aligned
physical address of a 4 byte memory area which must be in guest RAM and
must be zeroed.
The first, least significant bit of 4 byte memory location will be
written to by the hypervisor, typically at the time of interrupt
injection. Value of 1 means that guest can skip writing EOI to the apic
(using MSR or MMIO write); instead, it is sufficient to signal
EOI by clearing the bit in guest memory - this location will
later be polled by the hypervisor.
Value of 0 means that the EOI write is required.
It is always safe for the guest to ignore the optimization and perform
the APIC EOI write anyway.
Hypervisor is guaranteed to only modify this least
significant bit while in the current VCPU context, this means that
guest does not need to use either lock prefix or memory ordering
primitives to synchronise with the hypervisor.
However, hypervisor can set and clear this memory bit at any time:
therefore to make sure hypervisor does not interrupt the
guest and clear the least significant bit in the memory area
in the window between guest testing it to detect
whether it can skip EOI apic write and between guest
clearing it to signal EOI to the hypervisor,
guest must both read the least significant bit in the memory area and
clear it using a single CPU instruction, such as test and clear, or
compare and exchange.
