Lucas De Marchi 36bb0ea47b intel: annotate public functions
This was done with:
while read sym; do
	read f func line _ <<<$(cscope -d -L -1 $sym)
	if [ ! -z "$f" ]; then
		line=$((line-1))
		sed -i "${line}s/^/drm_public /" $f
	fi
done < /tmp/a.txt

Then some corner cases were manually fixed. "a.txt" above contains the
symbols collected from intel/intel-symbol-check. The idea here will be
to switch the default visibility to hidden so we don't export symbols we
shouldn't.

Tomasz Figa bb0fd5f3b3 intel: Do not use libpciaccess on Android
This patch makes the code not rely anymore on libpciaccess when compiled
for Android to eliminate ioperm() and iopl() syscalls required by that
library. As a side effect, the mappable aperture size is hardcoded to 64
MiB on Android, however nothing seems to rely on this value anyway, as
checked be grepping relevant code in drm_gralloc and Mesa.

This will prevent any more missing `#include "config.h"` bug, at the
cost of having to recompile some files that didn't need to be when
changing build options.

Michał Winiarski 8b4d57e7b7 intel: Add support for softpin
Softpin allows userspace to take greater control of GPU virtual address
space and eliminates the need of relocations. It can also be used to
mirror addresses between GPU and CPU (shared virtual memory).
Calls to drm_intel_bo_emit_reloc are still required to build the list of
drm_i915_gem_exec_objects at exec time, but no entries in relocs are
created. Self-relocs don't make any sense for softpinned objects and can
indicate a programming errors, thus are forbidden. Softpinned objects
are marked by asterisk in debug dumps.

Michel Thierry 3350add5cc intel: 48b ppgtt support (EXEC_OBJECT_SUPPORTS_48B_ADDRESS flag)
Gen8+ supports 48-bit virtual addresses, but some objects must always be
allocated inside the 32-bit address range.

In specific, any resource used with flat/heapless (0x00000000-0xfffff000)
General State Heap (GSH) or Instruction State Heap (ISH) must be in a
32-bit range, because the General State Offset and Instruction State Offset
are limited to 32-bits.

The i915 driver has been modified to provide a flag to set when the 4GB
limit is not necessary in a given bo (EXEC_OBJECT_SUPPORTS_48B_ADDRESS).
48-bit range will only be used when explicitly requested.

Callers to the existing drm_intel_bo_emit_reloc function should set the
use_48b_address_range flag beforehand, in order to use full ppgtt range.

v2: Make set/clear functions nops on pre-gen8 platforms, and use them
    internally in emit_reloc functions (Ben)
    s/48BADDRESS/48B_ADDRESS/ (Dave)
v3: Keep set/clear functions internal, no-one needs to use them directly.
v4: Don't set 48bit-support flag in emit reloc, check for ppgtt type
    before enabling set/clear function, print full offsets in debug
    statements, using port of lower_32_bits and upper_32_bits from linux
    kernel (Michał)

Emil Velikov 0f8da82500 drm: remove drm_public macro
Some compilers (like the Oracle Studio), require that the function
declaration must be annotated with the same visibility attribute as the
definition. As annotating functions with drm_public is no longer
required just remove the macro.

Tvrtko Ursulin ae8edc7544 intel: Add support for userptr objects
Allow userptr objects to be created and used via libdrm_intel.

At the moment tiling and mapping to GTT aperture is not supported
due hardware limitations across different generations and uncertainty
about its usefulness.

v2: Improved error handling in feature detection per review comments.

v3: Rebase on top of the drm_public addition, minor whitespace addition.

Jesse Barnes b50964027b libdrm/intel: execbuf2 support
This patch to libdrm adds support for the new execbuf2 ioctl.  If
detected, it will be used instead of the old ioctl.  By using the new
drm_intel_bufmgr_gem_enable_fenced_relocs(), you can indicate that any
time a fence register is actually required for a relocation target you
will call drm_intel_bo_emit_reloc_fence instead of
drm_intel_bo_emit_reloc, which will reduce fence register pressure.
