- * 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

+ *
+ * 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

+ * 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.

+ * 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

+ * 3. In live migration of user application, the state transitions from _RUNNING

+ * On state transition from _RUNNING to pre-copy, the driver should start

+ * 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.

+ * 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.
+ *

+ * 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

While we're at it, add a g_free() for the async_cmd_region that
is the last thing currently created. g_free() knows how to handle
NULL pointers, so this makes it easier to remember what cleanups
need to be performed when new regions are added.

The schib region can be used to obtain the latest SCHIB from the host
passthrough subchannel. Since the guest SCHIB is virtualized,
we currently only update the path related information so that the
guest is aware of any path related changes when it issues the
'stsch' instruction.

From: Eric Farman <farman@linux.ibm.com>
We have a use case (vfio-ccw) where a CRW is already built and
ready to use. Rather than teasing out the components just to
reassemble it later, let's rework this code so we can queue a
fully-qualified CRW directly.

The crw region can be used to obtain information about
Channel Report Words (CRW) from vfio-ccw driver.
Currently only channel-path related CRWs are passed to
QEMU from vfio-ccw driver.
