Simon Ser 4f06ce2550 render/gbm_allocator: avoid drmPrimeHandleToFD
Some drivers (e.g. nouveau) need to do some book-keeping when exporting
a BO handle to a DMA-BUF [1]. Using drmPrimeHandleToFD directly hides
the export from the user-space drivers and causes some ref'counting
issues.

So we can't properly handle BOs with a different handle for each plane
until [2] lands.

Simon Ser bf86110fc5 render/gbm_allocator: set modifier to INVALID if implicit
When gbm_bo_create is used and the GBM implementation does support
modifiers, gbm_bo_get_modifier may return something other than
DRM_FORMAT_MOD_INVALID. This can cause issues with the rest of the
stack (e.g. EGL or KMS) in case these don't support modifiers.

Instead, force the modifier to INVALID, to make sure no one uses
modifiers.

Simon Ser b5cefada92 render/gbm_allocator: export to DMA-BUF on init
Instead of lazily exporting BOs to DMA-BUFs, do it on init. This is
the only way to use the buffer, so there's no point in deferring
that work.

This is preparatory work for the next commit.

Simon Ser afdf4dc890 render/gles2: make EGL context current in bind_buffer
Instead of requiring callers to manually make the EGL context current
before binding a buffer and unsetting it after unbinding a buffer, do
it inside wlr_renderer_bind_buffer.

This hides renderer-specific implementation details inside the
wlr_renderer interface. Non-GLES2 renderers may not use EGL.
This removes all EGL dependencies from the backends.

Simon Ser 642b349e94 render/gles2: restore EGL context after texture operations
It can be surprising and unexpected that texture operations (such as

when it's done under-the-hood by wlroots in response to wl_surface

Simon Ser 7f9bbaaa17 render/egl: explicit client extension handling
Prior to this commit, wlr_egl_init seemed to assume the extension string
queried via EGL_NO_DISPLAY was a subset of the extension string queried
via an initialized display. This isn't correct.

EGL_EXT_client_extensions [1] defines two types of extensions: client
extensions and display extensions. The set of supported client and
display extensions are disjoint (ie. an extension is either a client or
a display extension, not both). Client extensions are queried via
EGL_NO_DISPLAY, display extensions are queried via an initialized
display.

Rename the variables to make this clear. Remove the misleading comment.
Log both client and display extensions.

Keeping textures bound results in hard-to-debug situations where some GL
operations incorrectly affect the texture.

Simon Ser 346b43e937 render: guard rendering operations between begin() and end()
Add a wlr_renderer.rendering bool, set it to true between
wlr_renderer_begin() and wlr_renderer_end(). Assert we're rendering when
calling functions that render.

Scott Anderson cff1c2f740 meson: Various improvements
Bumps minimum version to 0.51.0

- Remove all intermediate static libraries.
  They serve no purpose and are just add a bunch of boilerplate for
  managing dependencies and options. It's now managed as a list of
  files which are compiled into libwlroots directly.

- Use install_subdir instead of installing headers individually.
  I've changed my mind since I did that. Listing them out is annoying as
  hell, and it's easy to forget to do it.

- Add not_found_message for all of our optional dependencies that have a
  meson option. It gives some hints about what option to pass and what
  the optional dependency is for.

- Move all backend subdirectories into their own meson.build. This
keeps some of the backend-specific build logic (especially rdp and
session) more neatly separated off.

- Don't overlink example clients with code they're not using.
  This was done by merging the protocol dictionaries and setting some
  variables containing the code and client header file.
  Example clients now explicitly mention what extension protocols they
  want to link to.

- Split compositor example logic from client example logic.

- Minor formatting changes

Simon Ser 01818ad2c8 render: fix EGL extensions not loaded
Some extensions are only advertised by the EGL implementation with a
non-zero EGLDisplay. That's the case when the extension can only be
enabled when the hardware/driver supports it for instance.

Instead of checking for all extensions without a display, check only for
EGL_EXT_platform_base and EGL_KHR_debug which are used before
eglGetDisplay. Check for all other extensions when we have a display.

Closes: https://github.com/swaywm/wlroots/issues/1955

Simon Ser 515679e4fe Refactor EGL/GL API loading
Remove glapi.sh code generation, replace it with hand-written loading
code that checks extension strings before calling eglGetProcAddress.

The GLES2 renderer still uses global state because of:

- {PUSH,POP}_GLES2_DEBUG macros
- wlr_gles2_texture_from_* taking a wlr_egl instead of the renderer

Simon Ser 16e5e9541b Add -Wmissing-prototypes
This requires functions without a prototype definition to be static.
This allows to detect dead code, export less symbols and put shared
functions in headers.

Simon Ser 447835afc1 render/gles2: provide public API to access GL texture
Prior to this commit, compositors needed to render the texture to an
intermediate off-screen buffer using wlr_renderer APIs if they wanted to
use a custom rendering path (e.g. render to a 3D scene).

A new wlr_gles2_texture_get_attribs exposes the GL texture target and ID
so that compositors can render wlr_textures with their own shaders. An
example of a compositor doing so is available at [1].

Scott Anderson 85a2ee6d30 render/gles: Simplify textures a bit
We don't need our own enum for types. Instead we just use
GL_TEXTURE_{2D,EXTERNAL_OES}, which already describes usage.

Also fixes a situation where we were using GL_TEXTURE_2D in a situation
we should not have. wl_drm buffers are always GL_TEXTURE_EXTERNAL_OES,
no matter if they're RGB or any other format.

Simon Ser 51416738ea render/egl: prevent use-after-free when destroying current surface 2019-10-23 09:36:50 +00:00
Simon Ser 6bb7639a0f render/gles2: don't unset the current EGL surface when destroying texture
When a texture is destroyed between wlr_egl_make_current and
wlr_egl_swap_buffers, it resets the current EGL surface to NULL. This
makes wlr_egl_swap_buffers fail.

If the EGL context is already current, there's no need to reset it.
