/* anv Virtual Memory Layout
 * =========================
 *
 * When the anv driver is determining the virtual graphics addresses of memory
 * objects itself using the softpin mechanism, the following memory ranges
 * will be used.
 *
 * Three special considerations to notice:
 *
 * (1) the dynamic state pool is located within the same 4 GiB as the low
 * heap. This is to work around a VF cache issue described in a comment in
 * anv_physical_device_init_heaps.
 *
 * (2) the binding table pool is located at lower addresses than the surface
 * state pool, within a 4 GiB range. This allows surface state base addresses
 * to cover both binding tables (16 bit offsets) and surface states (32 bit
 * offsets).
 *
 * (3) the last 4 GiB of the address space is withheld from the high
 * heap. Various hardware units will read past the end of an object for
 * various reasons. This healthy margin prevents reads from wrapping around
 * 48-bit addresses.

/* Allowing different clear colors requires us to perform a depth resolve at
 * the end of certain render passes. This is because while slow clears store
 * the clear color in the HiZ buffer, fast clears (without a resolve) don't.
 * See the PRMs for examples describing when additional resolves would be
 * necessary. To enable fast clears without requiring extra resolves, we set
 * the clear value to a globally-defined one. We could allow different values
 * if the user doesn't expect coherent data during or after a render passes
 * (VK_ATTACHMENT_STORE_OP_DONT_CARE), but such users (aside from the CTS)
 * don't seem to exist yet. In almost all Vulkan applications tested thus far,
 * 1.0f seems to be the only value used. The only application that doesn't set
 * this value does so through the usage of an seemingly uninitialized clear
 * value.

 * fit into a signed 32 bits.  The only mechanism we have for dealing with
 * this at the moment is to limit all VkDeviceMemory objects to a maximum
 * of 2GB each.  The Vulkan spec allows us to do this:
 *
 *    "Some platforms may have a limit on the maximum size of a single
 *    allocation. For example, certain systems may fail to create
 *    allocations with a size greater than or equal to 4GB. Such a limit is
 *    implementation-dependent, and if such a failure occurs then the error
 *    VK_ERROR_OUT_OF_DEVICE_MEMORY should be returned."
 *
 * We don't use vk_error here because it's not an error so much as an
 * indication to the application that the allocation is too large.
