Adam Jackson 8e991ce539 egl: handle the full attrib list in display::options
Earlier spec is vague, although EGL 1.5 makes it clear:

     Multiple calls made to eglGetPlatformDisplay with the same
     parameters will return the same EGLDisplay handle.

With this commit we store and compare the full attrib list.

v2 (Emil):
 - Split into separate patches
 - Use EGLBoolean over int masked as such
 - Don't return free'd pointed on calloc failure

Eric Engestrom 54fa5eceae egl: use coherent variable names
`EGLDisplay` variables (the opaque Khronos type) have mostly been
consistently called `dpy`, as this is the name used in the Khronos
specs.

However, `_EGLDisplay` variables (our internal struct) have been
randomly called `dpy` when there was no local variable clash with
`EGLDisplay`s, and `disp` otherwise.

Let's be consistent and use `dpy` for the Khronos type, and `disp`
for our struct.

Emil Velikov 7552fcb7b9 egl: add base EGL_EXT_device_base implementation
Introduce the API for device query and enumeration. Those at the moment
produce nothing useful since zero devices are actually available.

That contradicts with the spec, so the extension isn't advertised just
yet.

With later commits we'll add support for software (always) and hardware
devices. Each one exposing the respective extension string.

v2:
 - fold API boilerplate into this patch
 - move _eglAddDevice, _eglDeviceSupports, _eglRefreshDeviceList to this
patch (Eric, Mathias)
 - make _eglFiniDevice the one called last

v3:
 - comment on the dummy _egl_device_extension enum entry (Eric)
 - annotate dev as MAYBE_UNUSED (Mathias)

Eric Engestrom a96749b13c egl: drop EGL driver `name`
This is a revert of Marek's 2cb9ab53dd revert.
It was needed to revert the previous commit, and didn't have any issue
itself.
--

The "DRI2" name was reported as confusing when printing EGL infos (one
user reported thinking DRI3 was not working on his X server), and the
only alternative is Haiku, which can only be used on a Haiku machine.

The name therefore doesn't add any information that the user wouldn't
know already, so let's just drop it.

That spec implies that EGL_TRUE should be returned in that case, yet
the ARM driver seems to return EGL_FALSE + EGL_BAD_SURFACE.

The Nvidia driver returns EGL_TRUE. We follow that behaviour until a
decision is made.

Emil Velikov 670cd4080b egl: remove unneeded _eglGetNativePlatform check
There's little point in calling _eglGetNativePlatform() in
eglCopyBuffers. The platform returned should be identical to the one
already stored in our _EGLDisplay.

In the following corner case, the check is incorrect.

The function _eglGetNativePlatform effectively invokes the old-style
eglGetDisplay platform selection. Thus if the EGL_PLATFORM platform does
not match with the EGL_EXT_platform_* used to create the display we'll
error out.

Addresses the egl-copy-buffers piglit test.

Chris Wilson 95ecf3df62 egl: Support IMG_context_priority
IMG_context_priority
https://www.khronos.org/registry/egl/extensions/IMG/EGL_IMG_context_priority.txt

    "This extension allows an EGLContext to be created with a priority
    hint. It is possible that an implementation will not honour the
    hint, especially if there are constraints on the number of high
    priority contexts available in the system, or system policy limits
    access to high priority contexts to appropriate system privilege
    level. A query is provided to find the real priority level assigned
    to the context after creation."

The extension adds a new eglCreateContext attribute for choosing a
priority hint. This stub parses the attribute and copies into the base
struct _egl_context, and hooks up the query similarly.

Since the attribute is purely a hint, I have no qualms about the lack of
implementation before reporting back the value the user gave!

v2: Remember to set the default ContextPriority value to medium.
v3: Use the driRendererQuery interface to probe the backend for
supported priority values and use those to mask the EGL interface.
v4: Treat the priority attrib as a hint and gracefully mask any requests
not supported by the driver, the EGLContext will remain at medium
priority.

Chad Versace 8f62d21bd7 egl: Partially revert 23c86c74, fix eglMakeCurrent
Fixes regressions in Android CtsVerifier.apk on Intel Chrome OS devices
due to incorrect error handling in eglMakeCurrent. See below on how to
confirm the regression is fixed.

This partially reverts

    commit 23c86c74cc
    Author:  Chad Versace <chadversary@chromium.org>
    Subject: egl: Emit error when EGLSurface is lost

The problem with commit 23c86c74 is that, once an EGLSurface became
lost, the app could never unbind the bad surface. Each attempt to unbind
the bad surface with eglMakeCurrent failed with EGL_BAD_CURRENT_SURFACE.

Specificaly, the bad commit added the error handling below. #2 and #3
were right, but #1 was wrong.

    1. eglMakeCurrent emits EGL_BAD_CURRENT_SURFACE if the calling
       thread has unflushed commands and either previous surface is no
       longer valid.

    2. eglMakeCurrent emits EGL_BAD_NATIVE_WINDOW if either new surface
       is no longer valid.

    3. eglSwapBuffers emits EGL_BAD_NATIVE_WINDOW if the swapped surface
       is no longer valid.

Whe I wrote the bad commit, I misunderstood the EGL spec language
for #1. The correct behavior is, if I understand correctly now, is
below. This patch doesn't implement the correct behavior, though, it
just reverts the broken behavior.

    - Assume a bound EGLSurface is no longer valid.
    - Assume the bound EGLContext has unflushed commands.
    - The app calls eglMakeCurrent. The spec requires eglMakeCurrent to
      implicitly flush. After flushing, eglMakeCurrent emits
      EGL_BAD_CURRENT_SURFACE and does *not* alter the thread's
      current bindings.
    - If the app calls eglMakeCurrent again, and the app inserts no
      commands into the GL command stream between the two eglMakeCurrent
      calls, then this second eglMakeCurrent succeeds without emitting an
      error.

How to confirm this fixes the regression:

    Download android-cts-verifier-7.1_r5-linux_x86-x86.zip from
    source.android.com, unpack, and `adb install CtsVerifier.apk`.
    Run test "Projection Cube". Click the Pass button (a
    green checkmark). Then run test "Projection Widget". Confirm that
    widgets are visible and that logcat does not complain about
    eglMakeCurrent failure.

    Then confirm there are no regressions in the cts-traded module that
    commit 263243b1 fixed:

        cts-tf > run cts --skip-preconditions --skip-device-info \
                 -m CtsCameraTestCases \
                 -t android.hardware.camera2.cts.RobustnessTest

    Tested with Chrome OS board "reef".

Emil Velikov 239e7ee91b egl: remove suprous header eglcompiler.h
The header is used only to provide STATIC_ASSERT. The latter is already
available in utils/macros.h so use that instead and kill of the header.

Chad Versace 23c86c74cc egl: Emit error when EGLSurface is lost
Add a new bool, _EGLSurface::Lost, and check it in eglMakeCurrent and
eglSwapBuffers. The EGL 1.5 spec says that those functions emit errors
when the native surface is no longer valid.

This patch just updates core EGL. No driver sets _EGLSurface::Lost yet.

I discovered that Mesa failed to detect lost surfaces while debugging an
Android CTS camera test,
android.hardware.camera2.cts.RobustnessTest#testAbandonRepeatingRequestSurface.
This patch doesn't fix the test though, though, because the test expects
EGL_BAD_SURFACE when the surface becomes lost, and this patch actually
complies with the EGL spec. If I interpreted the EGL spec correctly,
EGL_BAD_NATIVE_WINDOW or EGL_BAD_CURRENT_SURFACE is the correct error.

Kyle Brenneman ce562f9e3f EGL: Implement the libglvnd interface for EGL (v3)
The new interface mostly just sits on top of the existing library.

The only change to the existing EGL code is to split the client
extension string into platform extensions and everything else. On
non-glvnd builds, eglQueryString will just concatenate the two strings.

The EGL dispatch stubs are all generated. The script is based on the one
used to generate entrypoints in libglvnd itself.

v2: [Kyle]
 - Rebased against master.
 - Reworked the EGL makefile to use separate libraries
 - Made the EGL code generation scripts work with Python 2 and 3.
 - Change gen_egl_dispatch.py to use argparse for the command line arguments.
 - Assorted formatting and style cleanup in the Python scripts.

v3: [Emil Velikov]
 - Rebase
 - Remove separate glvnd glx/egl configure toggles
