+===========================================
+Userspace block device driver (ublk driver)
+===========================================
+
+Overview
+========
+
+ublk is a generic framework for implementing block device logic from userspace.
+The motivation behind it is that moving virtual block drivers into userspace,
+such as loop, nbd and similar can be very helpful. It can help to implement
+new virtual block device such as ublk-qcow2 (there are several attempts of
+implementing qcow2 driver in kernel).
+
+Userspace block devices are attractive because:
+
+- They can be written many programming languages.
+- They can use libraries that are not available in the kernel.
+- They can be debugged with tools familiar to application developers.
+- Crashes do not kernel panic the machine.
+- Bugs are likely to have a lower security impact than bugs in kernel
+ code.
+- They can be installed and updated independently of the kernel.
+- They can be used to simulate block device easily with user specified
+ parameters/setting for test/debug purpose
+
+ublk block device (``/dev/ublkb*``) is added by ublk driver. Any IO request
+on the device will be forwarded to ublk userspace program. For convenience,
+in this document, ``ublk server`` refers to generic ublk userspace
+program. ``ublksrv`` [#userspace]_ is one of such implementation. It
+provides ``libublksrv`` [#userspace_lib]_ library for developing specific
+user block device conveniently, while also generic type block device is
+included, such as loop and null. Richard W.M. Jones wrote userspace nbd device
+``nbdublk`` [#userspace_nbdublk]_ based on ``libublksrv`` [#userspace_lib]_.
+
+After the IO is handled by userspace, the result is committed back to the
+driver, thus completing the request cycle. This way, any specific IO handling
+logic is totally done by userspace, such as loop's IO handling, NBD's IO
+communication, or qcow2's IO mapping.
+
+``/dev/ublkb*`` is driven by blk-mq request-based driver. Each request is
+assigned by one queue wide unique tag. ublk server assigns unique tag to each
+IO too, which is 1:1 mapped with IO of ``/dev/ublkb*``.
+
+Both the IO request forward and IO handling result committing are done via
+``io_uring`` passthrough command; that is why ublk is also one io_uring based
+block driver. It has been observed that using io_uring passthrough command can
+give better IOPS than block IO; which is why ublk is one of high performance
+implementation of userspace block device: not only IO request communication is
+done by io_uring, but also the preferred IO handling in ublk server is io_uring
+based approach too.
+
+ublk provides control interface to set/get ublk block device parameters.
+The interface is extendable and kabi compatible: basically any ublk request
+queue's parameter or ublk generic feature parameters can be set/get via the
+interface. Thus, ublk is generic userspace block device framework.
+For example, it is easy to setup a ublk device with specified block
+parameters from userspace.
+
+Using ublk
+==========
+
+ublk requires userspace ublk server to handle real block device logic.
+
+Below is example of using ``ublksrv`` to provide ublk-based loop device.
+
+- add a device::
+
+ ublk add -t loop -f ublk-loop.img
+
+- format with xfs, then use it::
+
+ mkfs.xfs /dev/ublkb0
+ mount /dev/ublkb0 /mnt
+ # do anything. all IOs are handled by io_uring
+ ...
+ umount /mnt
+
+- list the devices with their info::
+
+ ublk list
+
+- delete the device::
+
+ ublk del -a
+ ublk del -n $ublk_dev_id
+
+See usage details in README of ``ublksrv`` [#userspace_readme]_.
+
+Design
+======
+
+Control plane
+-------------
+
+ublk driver provides global misc device node (``/dev/ublk-control``) for
+managing and controlling ublk devices with help of several control commands:
+
+- ``UBLK_CMD_ADD_DEV``
+
+ Add a ublk char device (``/dev/ublkc*``) which is talked with ublk server
+ WRT IO command communication. Basic device info is sent together with this
+ command. It sets UAPI structure of ``ublksrv_ctrl_dev_info``,
+ such as ``nr_hw_queues``, ``queue_depth``, and max IO request buffer size,
+ for which the info is negotiated with the driver and sent back to the server.
+ When this command is completed, the basic device info is immutable.
+
+- ``UBLK_CMD_SET_PARAMS`` / ``UBLK_CMD_GET_PARAMS``
+
+ Set or get parameters of the device, which can be either generic feature
+ related, or request queue limit related, but can't be IO logic specific,
+ because the driver does not handle any IO logic. This command has to be
+ sent before sending ``UBLK_CMD_START_DEV``.
+
+- ``UBLK_CMD_START_DEV``
+
+ After the server prepares userspace resources (such as creating per-queue
+ pthread & io_uring for handling ublk IO), this command is sent to the
+ driver for allocating & exposing ``/dev/ublkb*``. Parameters set via
+ ``UBLK_CMD_SET_PARAMS`` are applied for creating the device.
+
+- ``UBLK_CMD_STOP_DEV``
+
+ Halt IO on ``/dev/ublkb*`` and remove the device. When this command returns,
+ ublk server will release resources (such as destroying per-queue pthread &
+ io_uring).
+
+- ``UBLK_CMD_DEL_DEV``
+
+ Remove ``/dev/ublkc*``. When this command returns, the allocated ublk device
+ number can be reused.
+
+- ``UBLK_CMD_GET_QUEUE_AFFINITY``
+
+ When ``/dev/ublkc`` is added, the driver creates block layer tagset, so
+ that each queue's affinity info is available. The server sends
+ ``UBLK_CMD_GET_QUEUE_AFFINITY`` to retrieve queue affinity info. It can
+ set up the per-queue context efficiently, such as bind affine CPUs with IO
+ pthread and try to allocate buffers in IO thread context.
+
+- ``UBLK_CMD_GET_DEV_INFO``
+
+ For retrieving device info via ``ublksrv_ctrl_dev_info``. It is the server's
+ responsibility to save IO target specific info in userspace.
+
+Data plane
+----------
+
+ublk server needs to create per-queue IO pthread & io_uring for handling IO
+commands via io_uring passthrough. The per-queue IO pthread
+focuses on IO handling and shouldn't handle any control & management
+tasks.
+
+The's IO is assigned by a unique tag, which is 1:1 mapping with IO
+request of ``/dev/ublkb*``.
+
+UAPI structure of ``ublksrv_io_desc`` is defined for describing each IO from
+the driver. A fixed mmaped area (array) on ``/dev/ublkc*`` is provided for
+exporting IO info to the server; such as IO offset, length, OP/flags and
+buffer address. Each ``ublksrv_io_desc`` instance can be indexed via queue id
+and IO tag directly.
+
+The following IO commands are communicated via io_uring passthrough command,
+and each command is only for forwarding the IO and committing the result
+with specified IO tag in the command data:
+
+- ``UBLK_IO_FETCH_REQ``
+
+ Sent from the server IO pthread for fetching future incoming IO requests
+ destined to ``/dev/ublkb*``. This command is sent only once from the server
+ IO pthread for ublk driver to setup IO forward environment.
+
+- ``UBLK_IO_COMMIT_AND_FETCH_REQ``
+
+ When an IO request is destined to ``/dev/ublkb*``, the driver stores
+ the IO's ``ublksrv_io_desc`` to the specified mapped area; then the
+ previous received IO command of this IO tag (either ``UBLK_IO_FETCH_REQ``
+ or ``UBLK_IO_COMMIT_AND_FETCH_REQ)`` is completed, so the server gets
+ the IO notification via io_uring.
+
+ After the server handles the IO, its result is committed back to the
+ driver by sending ``UBLK_IO_COMMIT_AND_FETCH_REQ`` back. Once ublkdrv
+ received this command, it parses the result and complete the request to
+ ``/dev/ublkb*``. In the meantime setup environment for fetching future
+ requests with the same IO tag. That is, ``UBLK_IO_COMMIT_AND_FETCH_REQ``
+ is reused for both fetching request and committing back IO result.
+
+- ``UBLK_IO_NEED_GET_DATA``
+
+ With ``UBLK_F_NEED_GET_DATA`` enabled, the WRITE request will be firstly
+ issued to ublk server without data copy. Then, IO backend of ublk server
+ receives the request and it can allocate data buffer and embed its addr
+ inside this new io command. After the kernel driver gets the command,
+ data copy is done from request pages to this backend's buffer. Finally,
+ backend receives the request again with data to be written and it can
+ truly handle the request.
+
+ ``UBLK_IO_NEED_GET_DATA`` adds one additional round-trip and one
+ io_uring_enter() syscall. Any user thinks that it may lower performance
+ should not enable UBLK_F_NEED_GET_DATA. ublk server pre-allocates IO
+ buffer for each IO by default. Any new project should try to use this
+ buffer to communicate with ublk driver. However, existing project may
+ break or not able to consume the new buffer interface; that's why this
+ command is added for backwards compatibility so that existing projects
+ can still consume existing buffers.
+
+- data copy between ublk server IO buffer and ublk block IO request
+
+ The driver needs to copy the block IO request pages into the server buffer
+ (pages) first for WRITE before notifying the server of the coming IO, so
+ that the server can handle WRITE request.
+
+ When the server handles READ request and sends
+ ``UBLK_IO_COMMIT_AND_FETCH_REQ`` to the server, ublkdrv needs to copy
+ the server buffer (pages) read to the IO request pages.
+
+Future development
+==================
+
+Container-aware ublk deivice
+----------------------------
+
+ublk driver doesn't handle any IO logic. Its function is well defined
+for now and very limited userspace interfaces are needed, which is also
+well defined too. It is possible to make ublk devices container-aware block
+devices in future as Stefan Hajnoczi suggested [#stefan]_, by removing
+ADMIN privilege.
+
+Zero copy
+---------
+
+Zero copy is a generic requirement for nbd, fuse or similar drivers. A
+problem [#xiaoguang]_ Xiaoguang mentioned is that pages mapped to userspace
+can't be remapped any more in kernel with existing mm interfaces. This can
+occurs when destining direct IO to ``/dev/ublkb*``. Also, he reported that
+big requests (IO size >= 256 KB) may benefit a lot from zero copy.

+bond will see its upper master change. If that bond is moved into a bridge,
the bond's upper master will change. And so on. The driver will track such
movements to know what position a port is in in the overall topology by
registering for netdevice events and acting on NETDEV_CHANGEUPPER.

+ depends on ARM64_AMU_EXTN
+ default y
+ help
+ This option adds the workaround for ARM Cortex-A510 erratum 2457168.
+
+ The AMU counter AMEVCNTR01 (constant counter) should increment at the same rate
+ as the system counter. On affected Cortex-A510 cores AMEVCNTR01 increments
+ incorrectly giving a significantly higher output value.
+
+ Work around this problem by returning 0 when reading the affected counter in
+ key locations that results in disabling all users of this counter. This effect
+ is the same to firmware disabling affected counters.
+
+ If unsure, say Y.

- Enable this if you want to support 64bit kernel on PA-RISC platform.
-
- At the moment, only people willing to use more than 2GB of RAM,
- or having a 64bit-only capable PA-RISC machine should say Y here.
-
- Since there is no 64bit userland on PA-RISC, there is no point to
- enable this option otherwise. The 64bit kernel is significantly bigger
- and slower than the 32bit one.

+ * cgroup_attach_lock - Lock for ->attach()
+ * @lock_threadgroup: whether to down_write cgroup_threadgroup_rwsem
+ *
+ * cgroup migration sometimes needs to stabilize threadgroups against forks and
+ * exits by write-locking cgroup_threadgroup_rwsem. However, some ->attach()
+ * implementations (e.g. cpuset), also need to disable CPU hotplug.
+ * Unfortunately, letting ->attach() operations acquire cpus_read_lock() can
+ * lead to deadlocks.
+ *
+ * Bringing up a CPU may involve creating and destroying tasks which requires
+ * read-locking threadgroup_rwsem, so threadgroup_rwsem nests inside
+ * cpus_read_lock(). If we call an ->attach() which acquires the cpus lock while
+ * write-locking threadgroup_rwsem, the locking order is reversed and we end up
+ * waiting for an on-going CPU hotplug operation which in turn is waiting for
+ * the threadgroup_rwsem to be released to create new tasks. For more details:

-List hybrid event
------------------
-
As before, use perf-list to list the symbolic event.
perf list
be supported.
Enable hybrid event with a specific pmu
----------------------------------------
To enable a core only event or atom only event, following syntax is supported:
perf stat -e cpu_core/cycles/
Create two events for one hardware event automatically
-------------------------------------------------------
When creating one event and the event is available on both atom and core,
two events are created automatically. One is for atom, the other is for
The first 'cycles' is core event, the second 'cycles' is atom event.
Thread mode example:
---------------------
perf-stat reports the scaled counts for hybrid event and with a percentage
displayed. The percentage is the event's running time/enabling time.
604,097,080 cpu_atom/cycles/ (99.57%)
perf-record:
-------------
If there is no '-e' specified in perf record, on hybrid platform,
it creates two default 'cycles' and adds them to event list. One
is for core, the other is for atom.
perf-stat:
-----------
If there is no '-e' specified in perf stat, on hybrid platform,
besides of software events, following events are created and
- abort_tx: only when the target is a hardware transaction abort
- cond: conditional branches
- save_type: save branch type during sampling in case binary is not available later
+ For the platforms with Intel Arch LBR support (12th-Gen+ client or
+ 4th-Gen Xeon+ server), the save branch type is unconditionally enabled
+ when the taken branch stack sampling is enabled.
+
The option requires at least one branch type among any, any_call, any_ret, ind_call, cond.
defaults to CPU layout. Masks defined or provided by the option value are
filtered through the mask provided by -C option.

--debuginfod[=URLs]::
Specify debuginfod URL to be used when cacheing perf.data binaries,
it follows the same syntax as the DEBUGINFOD_URLS variable, like:
only, as of now. So the applications built without the frame
pointer might see bogus addresses.
