composer@2.x-hal is a header library. Any of the shared
libraries it depends on must also be included by anyone
who includes composer@2.x-hal. This means when we add a new
version of mapper, anyone who uses composer@2.x-hal must
also include the new version of the mapper. Vendors
that depend on composer@2.x-hal are broken every time we
add a new mapper.
This patch refactors ComposerResources into a seperate
shared library. ComposerResources contains all of the
mapper code. composer@2.x-hal will depend on the new
composer@2.x-resource hal. Everyone downstream must
also add the composer@2.x-resource file now. However,
they will not be broken again when we add a new mapper
version.
Bug: 136016160
Test: Compiles and boots
Change-Id: I208a954a941ed65938074cd3efb8a6893a2bc1eb
This adds
android.hardware.graphics.composer@2.2-hal
android.hardware.graphics.composer@2.2-passthrough
android.hardware.graphics.composer@2.2-service
The -hal module makes it easier to write composer 2.2 HAL and is
reusable by vendors. The -passthrough module provides a HwcHal
class that implements ComposerHal 2.2 on top of hwcomposer2, and is
also resuable by vendors. Finally, the -service module provides a
(stub) default implementation.
Test: boots and VTS
