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.

Lucas De Marchi 4e81d4f9c9 intel: add generic functions to check PCI ID
This will allow platforms to reuse kernel IDs instead of manually
keeping them in sync. In most of the cases we only need to extend
IS_9XX().  Current platforms that fit this requirement can be ported
over to use this macro. Right now it's a nop since it doesn't have any
PCI ID added.

The i915_pciids.h header is in sync with kernel tree on
drm-tip 2018y-08m-20d-21h-41m-11s.

v2: - move to a separate .c so we can have the array in a single
      compilation unit
    - use a single array for all gens
    - add real functions to get or check gen by pciid
    - define our own pci device struct rather than inherit the one
      kernel uses: we can throw away most of the fields

v3: - add comment to keep ids sorted by gen
    - remove misleading comment about all gens

This reverts commit ed07718ae7.

The commit added a guard since libpciaccess may be missing on some

Android POV.

Hence, we can revert this workaround - which caused similar breakage to
the one it's trying to fix. This time in Mesa.

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.

John Stultz ed07718ae7 libdrm: intel/Android.mk: Filter libdrm_intel library requirements on x86/x86_64
When building AOSP after updating libdrm project to the
freedesktop/master branch, I've seen the following build errors:

external/libdrm/intel/Android.mk: error: libdrm_intel
(SHARED_LIBRARIES android-arm64) missing libpciaccess
(SHARED_LIBRARIES android-arm64) You can set
ALLOW_MISSING_DEPENDENCIES=true in your environment if this is
intentional, but that may defer real problems until later in the
build.

Using ALLOW_MISSING_DEPENDENCIES=true when building allows
things to function properly, but is not ideal.

So basically, while I'm not including the libdrm_intel package
into the build, just the fact that the Android.mk file references
libpciaccess which isn't a repo included in AOSP causes the build
failure.

So it seems we need some sort of conditional filter in the
Android.mk to skip over it if we're not building for intel.

Emil Velikov 03d2e91d00 android: introduce Android.common.mk to reduce boilerplate
... across the makefiles. Currently this isn't much but that will change
shortly.

As an added bonus this fixes all present and future cases where we've
forgotten to strip out the headers from LOCAL_SRC_FILES.

In a couple of cases (the tests) we start setting
LOCAL_EXPORT_C_INCLUDE_DIRS, which shouldn't be an issue.

Emil Velikov de5b41ef5a android: remove LOCAL_MODULE_TAGS := optional tag
Seems to be the default option since ~2009 with commit 2f31293ba78 "auto
import from //branches/cupcake/...@137197". Fleshed out from a larger
commit in the AOSP repo/fork.
