/*
* 16Bx2 Block Linear layout, used by desktop GPUs, and Tegra K1 and later
* Generalized Block Linear layout, used by desktop GPUs starting with NV50/G80,
* and Tegra GPUs starting with Tegra K1.
*
* Pixels are arranged in Groups of Bytes (GOBs). GOB size and layout varies
* based on the architecture generation. GOBs themselves are then arranged in
* 3D blocks, with the block dimensions (in terms of GOBs) always being a power
* of two, and hence expressible as their log2 equivalent (E.g., "2" represents
* a block depth or height of "4").
*
* Chapter 20 "Pixel Memory Formats" of the Tegra X1 TRM describes this format
* in full detail.
*
* Macro
* Bits Param Description
* ---- ----- -----------------------------------------------------------------
*
* 3:0 h log2(height) of each block, in GOBs. Placed here for
* compatibility with the existing
* DRM_FORMAT_MOD_NVIDIA_16BX2_BLOCK()-based modifiers.
*
* 4:4 - Must be 1, to indicate block-linear layout. Necessary for
* compatibility with the existing
* DRM_FORMAT_MOD_NVIDIA_16BX2_BLOCK()-based modifiers.
*
* 8:5 - Reserved (To support 3D-surfaces with variable log2(depth) block
* size). Must be zero.
*
* Note there is no log2(width) parameter. Some portions of the
* hardware support a block width of two gobs, but it is impractical
* to use due to lack of support elsewhere, and has no known
* benefits.
*
* 11:9 - Reserved (To support 2D-array textures with variable array stride
* in blocks, specified via log2(tile width in blocks)). Must be
* zero.
*
* 19:12 k Page Kind. This value directly maps to a field in the page
* tables of all GPUs >= NV50. It affects the exact layout of bits
* in memory and can be derived from the tuple
*
* (format, GPU model, compression type, samples per pixel)
*
* Where compression type is defined below. If GPU model were
* implied by the format modifier, format, or memory buffer, page
* kind would not need to be included in the modifier itself, but
* since the modifier should define the layout of the associated
* memory buffer independent from any device or other context, it
* must be included here.
*
* 21:20 g GOB Height and Page Kind Generation. The height of a GOB changed
* starting with Fermi GPUs. Additionally, the mapping between page
* kind and bit layout has changed at various points.
*
* 0 = Gob Height 8, Fermi - Volta, Tegra K1+ Page Kind mapping
* 1 = Gob Height 4, G80 - GT2XX Page Kind mapping
* 2 = Gob Height 8, Turing+ Page Kind mapping
* 3 = Reserved for future use.
*
* 22:22 s Sector layout. On Tegra GPUs prior to Xavier, there is a further
* bit remapping step that occurs at an even lower level than the
* page kind and block linear swizzles. This causes the layout of
* surfaces mapped in those SOC's GPUs to be incompatible with the
* equivalent mapping on other GPUs in the same system.
*
* 0 = Tegra K1 - Tegra Parker/TX2 Layout.
* 1 = Desktop GPU and Tegra Xavier+ Layout
*
* 25:23 c Lossless Framebuffer Compression type.
*
* 0 = none
* 1 = ROP/3D, layout 1, exact compression format implied by Page
* Kind field
* 2 = ROP/3D, layout 2, exact compression format implied by Page
* Kind field
* 3 = CDE horizontal
* 4 = CDE vertical
* 5 = Reserved for future use
* 6 = Reserved for future use
* 7 = Reserved for future use
*
* 55:25 - Reserved for future use. Must be zero.

/*
* Each virtio-mem device manages a dedicated region in physical address
* space. Each device can belong to a single NUMA node, multiple devices
* for a single NUMA node are possible. A virtio-mem device is like a
* "resizable DIMM" consisting of small memory blocks that can be plugged
* or unplugged. The device driver is responsible for (un)plugging memory
* blocks on demand.
*
* Virtio-mem devices can only operate on their assigned memory region in
* order to (un)plug memory. A device cannot (un)plug memory belonging to
* other devices.
*
* The "region_size" corresponds to the maximum amount of memory that can
* be provided by a device. The "size" corresponds to the amount of memory
* that is currently plugged. "requested_size" corresponds to a request
* from the device to the device driver to (un)plug blocks. The
* device driver should try to (un)plug blocks in order to reach the
* "requested_size". It is impossible to plug more memory than requested.
*
* The "usable_region_size" represents the memory region that can actually
* be used to (un)plug memory. It is always at least as big as the
* "requested_size" and will grow dynamically. It will only shrink when
* explicitly triggered (VIRTIO_MEM_REQ_UNPLUG).
*
* There are no guarantees what will happen if unplugged memory is
* read/written. Such memory should, in general, not be touched. E.g.,
* even writing might succeed, but the values will simply be discarded at
* random points in time.
*
* It can happen that the device cannot process a request, because it is
* busy. The device driver has to retry later.
*
* Usually, during system resets all memory will get unplugged, so the
* device driver can start with a clean state. However, in specific
* scenarios (if the device is busy) it can happen that the device still
* has memory plugged. The device driver can request to unplug all memory
* (VIRTIO_MEM_REQ_UNPLUG) - which might take a while to succeed if the
* device is busy.

* migration information. Field accesses from this structure are only supported

* vendor drivers should return an error.
*
* device_state: (read/write)
* - The user application writes to this field to inform the vendor driver
* about the device state to be transitioned to.
* - The vendor driver should take the necessary actions to change the
* device state. After successful transition to a given state, the
* vendor driver should return success on write(device_state, state)
* system call. If the device state transition fails, the vendor driver
* should return an appropriate -errno for the fault condition.
* - On the user application side, if the device state transition fails,
* that is, if write(device_state, state) returns an error, read
* device_state again to determine the current state of the device from
* the vendor driver.
* - The vendor driver should return previous state of the device unless
* the vendor driver has encountered an internal error, in which case
* the vendor driver may report the device_state VFIO_DEVICE_STATE_ERROR.
* - The user application must use the device reset ioctl to recover the
* device from VFIO_DEVICE_STATE_ERROR state. If the device is
* indicated to be in a valid device state by reading device_state, the
* user application may attempt to transition the device to any valid
* state reachable from the current state or terminate itself.
*
* device_state consists of 3 bits:
* - If bit 0 is set, it indicates the _RUNNING state. If bit 0 is clear,
* it indicates the _STOP state. When the device state is changed to
* _STOP, driver should stop the device before write() returns.
* - If bit 1 is set, it indicates the _SAVING state, which means that the
* driver should start gathering device state information that will be
* provided to the VFIO user application to save the device's state.
* - If bit 2 is set, it indicates the _RESUMING state, which means that
* the driver should prepare to resume the device. Data provided through
* the migration region should be used to resume the device.
* Bits 3 - 31 are reserved for future use. To preserve them, the user
* application should perform a read-modify-write operation on this
* field when modifying the specified bits.

* 0. Default state of VFIO device is _RUNNNG when the user application starts.
* 1. During normal shutdown of the user application, the user application may
* optionally change the VFIO device state from _RUNNING to _STOP. This
* transition is optional. The vendor driver must support this transition but
* must not require it.
* 2. When the user application saves state or suspends the application, the
* device state transitions from _RUNNING to stop-and-copy and then to _STOP.
* On state transition from _RUNNING to stop-and-copy, driver must stop the
* device, save the device state and send it to the application through the
* migration region. The sequence to be followed for such transition is given
* below.
* 3. In live migration of user application, the state transitions from _RUNNING
* to pre-copy, to stop-and-copy, and to _STOP.
* On state transition from _RUNNING to pre-copy, the driver should start
* gathering the device state while the application is still running and send
* the device state data to application through the migration region.
* On state transition from pre-copy to stop-and-copy, the driver must stop
* the device, save the device state and send it to the user application
* through the migration region.
* Vendor drivers must support the pre-copy state even for implementations
* where no data is provided to the user before the stop-and-copy state. The
* user must not be required to consume all migration data before the device
* transitions to a new state, including the stop-and-copy state.
* The sequence to be followed for above two transitions is given below.
* 4. To start the resuming phase, the device state should be transitioned from
* the _RUNNING to the _RESUMING state.
* In the _RESUMING state, the driver should use the device state data
* received through the migration region to resume the device.
* 5. After providing saved device data to the driver, the application should
* change the state from _RESUMING to _RUNNING.
*
* reserved:
* Reads on this field return zero and writes are ignored.
*
* pending_bytes: (read only)
* The number of pending bytes still to be migrated from the vendor driver.
*
* data_offset: (read only)
* The user application should read data_offset field from the migration
* region. The user application should read the device data from this
* offset within the migration region during the _SAVING state or write
* the device data during the _RESUMING state. See below for details of
* sequence to be followed.
*
* data_size: (read/write)
* The user application should read data_size to get the size in bytes of
* the data copied in the migration region during the _SAVING state and
* write the size in bytes of the data copied in the migration region
* during the _RESUMING state.
*
* The format of the migration region is as follows:
* ------------------------------------------------------------------
* |vfio_device_migration_info| data section |
* | | /////////////////////////////// |
* ------------------------------------------------------------------
* ^ ^
* offset 0-trapped part data_offset
*
* The structure vfio_device_migration_info is always followed by the data
* section in the region, so data_offset will always be nonzero. The offset
* from where the data is copied is decided by the kernel driver. The data
* section can be trapped, mmapped, or partitioned, depending on how the kernel
* driver defines the data section. The data section partition can be defined
* as mapped by the sparse mmap capability. If mmapped, data_offset must be
* page aligned, whereas initial section which contains the
* vfio_device_migration_info structure, might not end at the offset, which is
* page aligned. The user is not required to access through mmap regardless
* of the capabilities of the region mmap.
* The vendor driver should determine whether and how to partition the data
* section. The vendor driver should return data_offset accordingly.
*
* The sequence to be followed while in pre-copy state and stop-and-copy state
* is as follows:
* a. Read pending_bytes, indicating the start of a new iteration to get device
* data. Repeated read on pending_bytes at this stage should have no side
* effects.
* If pending_bytes == 0, the user application should not iterate to get data
* for that device.
* If pending_bytes > 0, perform the following steps.
* b. Read data_offset, indicating that the vendor driver should make data
* available through the data section. The vendor driver should return this
* read operation only after data is available from (region + data_offset)
* to (region + data_offset + data_size).
* c. Read data_size, which is the amount of data in bytes available through
* the migration region.
* Read on data_offset and data_size should return the offset and size of
* the current buffer if the user application reads data_offset and
* data_size more than once here.
* d. Read data_size bytes of data from (region + data_offset) from the
* migration region.
* e. Process the data.
* f. Read pending_bytes, which indicates that the data from the previous
* iteration has been read. If pending_bytes > 0, go to step b.
*
* The user application can transition from the _SAVING|_RUNNING
* (pre-copy state) to the _SAVING (stop-and-copy) state regardless of the
* number of pending bytes. The user application should iterate in _SAVING
* (stop-and-copy) until pending_bytes is 0.
*
* The sequence to be followed while _RESUMING device state is as follows:
* While data for this device is available, repeat the following steps:
* a. Read data_offset from where the user application should write data.
* b. Write migration data starting at the migration region + data_offset for
* the length determined by data_size from the migration source.
* c. Write data_size, which indicates to the vendor driver that data is
* written in the migration region. Vendor driver must return this write
* operations on consuming data. Vendor driver should apply the
* user-provided migration region data to the device resume state.
*
* If an error occurs during the above sequences, the vendor driver can return
* an error code for next read() or write() operation, which will terminate the
* loop. The user application should then take the next necessary action, for
* example, failing migration or terminating the user application.
*
* For the user application, data is opaque. The user application should write
* data in the same order as the data is received and the data should be of
* same transaction size at the source.
