broadcom: Add V3D 3.3 gallium driver called "vc5", for BCM7268.
V3D 3.3 is a continuation of the 3D implementation in VC4 (v2.1 and v2.6).
V3D 3.3 introduces an MMU (no more CMA allocations) and support for
GLES3.1. This driver is not currently conformant, though that will be a
target as soon as possible.
V3D 3.x parts use a new texture tiling layout common across many Broadcom
graphics parts including and the HVS scanout engine. It also massively
changes the QPU instructions, introducing a common physical register file
(no more A/B split) and half-float instructions, while removing the 4x8
unorm instructions in favor of half-float for talking to fixed function
interfaces. Because so much has changed, vc5 is implemented in a separate
gallium driver, using only the XML code-generation support from vc4.
v2: Fix tile layout for 64bpp textures. Fix texture swizzling for 32-bit
returns. Fix up a bit of MRT setup. Sync the simulator to kernel
behavior a bit more. Improve uniform debugging code. Rebase on
QIR->VIR rename. Move texture state mostly to the CSOs. Improve
cache flushing on the simulator. Fix program deletion
use-after-frees.

Generally, VC5 driver BOs have a + * GEM-side copy of their contents and a simulator-side memory area that the + * GEM contents get copied into during simulation. Once simulation is done, + * the simulator's data is copied back out to the GEM BOs, so that rendering + * appears on the screen as if actual hardware rendering had been done. + * + * One of the limitations of this code is that we shouldn't really need a + * GEM-side BO for non-window-system BOs. However, do we need unique BO + * handles for each of our GEM bos so that this file can look up its state + * from the handle passed in at submit ioctl time (also, a couple of places + * outside of this file still call ioctls directly on the fd). + * + * Another limitation is that BO import doesn't work unless the underlying + * window system's BO size matches what VC5 is going to use, which of course + * doesn't work out in practice. This means that for now, only DRI3 (VC5 + * makes the winsys BOs) is supported, not DRI2 (window system makes the winys + * BOs). + */ + +#ifdef USE_VC5_SIMULATOR + +#include <sys/mman.h> +#include "util/hash_table.h" +#include "util/ralloc.h" +#include "util/set.h" +#include "util/u_memory.h" +#include "util/u_mm.h" + +#define HW_REGISTER_RO(x) (x) +#define HW_REGISTER_RW(x) (x) +#include "libs/core/v3d/registers/3.3.0.0/v3d.h" + +#include "vc5_screen.h" +#include "vc5_context.h" +#define V3D_TECH_VERSION 3 +#define V3D_REVISION 3 +#define V3D_SUB_REV 0 +#define V3D_HIDDEN_REV 0 +#undef unreachable +#include "v3d_hw_auto.h" + +/** Global (across GEM fds) state for the simulator */ +static struct vc5_simulator_state { + mtx_t mutex; + + struct v3d_hw *v3d; + + /* Base virtual address of the heap. */ + void *mem; + /* Base hardware address of the heap. */ + uint32_t mem_base; + /* Size of the heap. */ + size_t mem_size; + + struct mem_block *heap; + struct mem_block *overflow; + + /** Mapping from GEM handle to struct vc5_simulator_bo * */ + struct hash_table *fd_map; + + int refcount; +} sim_state = { + .mutex = _MTX_INITIALIZER_NP, +}; + +/** Per-GEM-fd state for the simulator. */ +struct vc5_simulator_file { + int fd; + + /** Mapping from GEM handle to struct vc5_simulator_bo * */ + struct hash_table *bo_map; + + struct mem_block *gmp; + void *gmp_vaddr; +}; + +/** Wrapper for drm_vc5_bo tracking the simulator-specific state. */ +struct vc5_simulator_bo { + struct vc5_simulator_file *file; + + /** Area for this BO within sim_state->mem */ + struct mem_block *block; + uint32_t size; + void *vaddr; + + void *winsys_map; + uint32_t winsys_stride; + + int handle; +}; + +static void * +int_to_key(int key) +{ + return (void *)(uintptr_t)key; +} + +static struct vc5_simulator_file * +vc5_get_simulator_file_for_fd(int fd) +{ + struct hash_entry *entry = _mesa_hash_table_search(sim_state.fd_map, + int_to_key(fd + 1)); + return entry ?
