Subject: Track the last release fence per layer stack

Merging fences prior to calling CompositionEngine#present results in
occassional missed frames in Surfaceflinger. Merging fences here was
originally needed to relieve memory pressure. Instead, we can track
each layer stack's future release fence with a map between a layer
stack and its last fence, as it can be assumed that multiple fences
for the same layer stack can be be dropped.

Fixes: b/330841053
Test: SurfaceFlinger_test
Test: presubmit

Subject: Delete unneeded filegroup

The libui_host_common file group was created to be able to include
certain files from libui into a host build without having to make the
entire library host compatible. This is exactly what libui-types has
done, so that can be used instead of this filegroup.

Test: build libhostgraphics

Subject: ui: Refactor DisplayIdentification to use ftl::stable_hash

Replace cityHash64Len0To16 with ftl::stable_hash which can handle up to
64 bytes string instead of just up to 16.

Bug: 194863377
Test: DisplayIdentification_test

Subject: Use a strongly typed LogicalDisplayId for displayId(2/n)

Currently, we use int32_t for displayId, which is not a safe type, and
it may also lead to misdefinition of types. Here, we introduce
LogicalDisplayId as a strong type for displayId and move all contents
of constants.h into LogicalDisplayId.h.

From cfbee5304f8fa7210e6f0816ca2ef2b6ab22c689 Mon Sep 17 00:00:00 2001
From: Siarhei Vishniakou <svv@google.com>
Date: Fri, 10 May 2024 13:41:35 -0700
Subject: Move ADISPLAY_ID_ definitions into LogicalDisplayId

These will eventually replace the existing definitions as follows:
     ADISPLAY_ID_NONE -->> LogicalDisplayId::INVALID
     ADISPLAY_ID_DEFAULT -->> LogicalDisplayId::DEFAULT

We are keeping the old definitions for now, to reduce the merge
conflicts. These will be removed in subsequent CLs, after the
frameworks/base and other repository patches go in.

The constant "NONE" was renamed to "INVALID" to make it consistent with
the Java definitions.

Bug: 339106983
Test: m checkinput
Change-Id: I0274be345159c85cb51fcea743d8acd3d298cd07

Subject: ui: Refactor stable ID generation for GPU virtual displays

This is a partial port of  http://ag/17832464 for main.

Use ftl::stable_hash to generate stable ID from uniqueId for GPU virtual
displays. This allows FLAG_STABLE consistent with PhysicalDisplayId that
uses a unique EDID, as well as being stable across reboots when using
hardcoded or static unique ID.

Add DisplayId.isStable()/isVirtual() interfaces and refactor previous
legacy usages.

Bug: 339525838
Bug: 137375833
Bug: 194863377
Test: atest libsurfaceflinger_unittest
Test: atest DisplayId_test
Flag: EXEMPT refactor

Subject: Reland "ui: Refactor stable ID generation for GPU virtual displays"

This is a partial port of ag/17832464 for main with additional tests.

Use ftl::stable_hash to generate stable ID from uniqueId for GPU virtual
displays. This allows FLAG_STABLE consistent with PhysicalDisplayId that
uses a unique EDID, as well as being stable across reboots when using
hardcoded or static unique ID.

Add DisplayId.isStable()/isVirtual() interfaces and refactor previous
legacy usages.
