Jakob Bornecrantz | 3192633 | 2009-11-16 19:56:18 +0100 | [diff] [blame] | 389 | * |
| 390 | * When the SVGA3D device asynchronously processes this FIFO |
| 391 | * command, a DMA operation is performed between host VRAM and |
| 392 | * a generic SVGAGuestPtr. The guest pointer may refer to guest |
| 393 | * VRAM (provided by the SVGA PCI device) or to guest system |
| 394 | * memory that has been set up as a Guest Memory Region (GMR) |
| 395 | * by the SVGA device. |
| 396 | * |
| 397 | * The guest's DMA buffer must remain valid (not freed, paged out, |
| 398 | * or overwritten) until the host has finished processing this |
| 399 | * command. The guest can determine that the host has finished |
| 400 | * by using the SVGA device's FIFO Fence mechanism. |
| 401 | * |
| 402 | * The guest's image buffer can be an arbitrary size and shape. |
| 403 | * Guest image data is interpreted according to the SVGA3D surface |
| 404 | * format specified when the surface was defined. |
| 405 | * |
| 406 | * The caller may optionally define the guest image's pitch. |
| 407 | * guestImage->pitch can either be zero (assume image is tightly |
| 408 | * packed) or it must be the number of bytes between vertically |
| 409 | * adjacent image blocks. |
| 410 | * |
| 411 | * The provided copybox list specifies which regions of the source |
| 412 | * image are to be copied, and where they appear on the destination. |
| 413 | * |
| 414 | * NOTE: srcx/srcy are always on the guest image and x/y are |
| 415 | * always on the host image, regardless of the actual transfer |
| 416 | * direction! |
| 417 | * |
| 418 | * For efficiency, the SVGA3D device is free to copy more data |
| 419 | * than specified. For example, it may round copy boxes outwards |
| 420 | * such that they lie on particular alignment boundaries. |
