* egl: use coherent variable namesEric Engestrom2019-02-061-4/+4
| | | | | | | | | | | | | | | | | `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.

* egl: Simplify queries for EGL_RENDER_BUFFERChad Versace2018-08-071-3/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There exist *two* queryable EGL_RENDER_BUFFER states in EGL: eglQuerySurface(EGL_RENDER_BUFFER) and eglQueryContext(EGL_RENDER_BUFFER). These changes eliminate potentially very fragile code in the upcoming EGL_KHR_mutable_render_buffer implementation. * eglQuerySurface(EGL_RENDER_BUFFER) The implementation of eglQuerySurface(EGL_RENDER_BUFFER) contained abstruse logic which required comprehending the specification complexities of how the two EGL_RENDER_BUFFER states interact. The function sometimes returned _EGLContext::WindowRenderBuffer, sometimes _EGLSurface::RenderBuffer. Why? The function tried to encode the actual logic from the EGL spec. When did the function return which variable? Go study the EGL spec, hope you understand it, then hope Mesa mutated the EGL_RENDER_BUFFER state in all the correct places. Have fun. To simplify eglQuerySurface(EGL_RENDER_BUFFER), and to improve confidence in its correctness, flatten its indirect logic. For pixmap and pbuffer surfaces, simply return a hard-coded literal value, as the spec suggests. For window surfaces, simply return _EGLSurface::RequestedRenderBuffer. Nothing difficult here. * eglQueryContext(EGL_RENDER_BUFFER) The implementation of this suffered from the same issues as eglQuerySurface, and the solution is the same. confidence in its correctness, flatten its indirect logic. For pixmap and pbuffer surfaces, simply return a hard-coded literal value, as the spec suggests. For window surfaces, simply return _EGLSurface::ActiveRenderBuffer.

* egl: Support IMG_context_priorityChris Wilson2017-10-201-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* egl/main: no longer export internal functionEmil Velikov2015-03-051-2/+2
| | | | | | | | | | | | With the split of the gallium egl module we had previously it required access to some of the internal functions. As the only build (automake) that did this no longer builds it we can now appropriately hide those functions.

* egl: Add reference count for resources.Chia-I Wu2010-10-231-0/+22
| | | | | This is a really simple mechanism. There is no atomicity and the caller is expected to hold the display lock.
* egl: Drop dpy argument from the link functions.Chia-I Wu2010-10-231-3/+3
| | | | | All display resources are already initialized with a display. Linking simply links a resource to its display.

| | | | We do not want them to be all over the places.
* egl: Clarify IsLinked and IsBound.Chia-I Wu2010-02-051-0/+6
| | | | | | Both a link and a binding creates a reference to the resource. Drivers should not destroy the resource when there is a reference. The difference is better described in doc/egl.html.
* egl: Initialize display resources with their display.Chia-I Wu2010-01-311-1/+1
| | | | | | | Change _eglInitSurface, _eglInitContext, and _eglInitImage to take an _EGLDisplay instead of an _EGLDriver. This is a more natural form, and plus, the display encodes information such as the extensions supported that might be required for attribute list parsing.

| | | | | _eglMakeCurrent is a big hammer that is not easy to use. Migrate drivers to use _eglBindContext and un-export _eglMakeCurrent.
* egl: Add _eglBindContext.Chia-I Wu2010-01-281-0/+4
| | | | | | It works similar to _eglMakeCurrent, except that the old context and surfaces are returned instead of destroyed. _eglMakeCurrent is now calling the new _eglBindContext.

* egl: Overhaul driver API.Chia-I Wu2009-08-181-5/+5
| | | | | | | | | | | | The motivation is so that drivers do not need to look up and check for bad display, context, and etc. It also becomes unnecessary for drivers to call the link functions. This commit makes eglapi.[ch] do the lookup and check. As a result, the driver API is overhauled, and almost all sources and drivers need update. The updates are mainly find and replace with human brains. Signed-off-by: Chia-I Wu <[email protected]>

* egl: Remove redundant DeletePending flag.Chia-I Wu2009-07-171-1/+0

* egl: Add funtions to link contexts and surfaces to displays.Chia-I Wu2009-07-171-9/+3
| | | | | | | | | | | | | | | | | EGL contexts and surfaces are resources of displays. They should be managed by displays. This commit adds a bunch of functions to egldisplay.c to help establish the links between contexts/surfaces and displays. How links are established is considered opaque outside display. Functions like _eglGetSurfaceHandle or _eglLookupSurface are therefore moved to egldisplay.c, with some small modifications. The idea is also extended to display. That is, displays need to link to themselves to be looked up. This commit only adds the functions. A commit to use them should follow. Signed-off-by: Chia-I Wu <[email protected]>

| | | | | | | | | This commit introduces a "current" system to manage per-thread info. It uses TLS, if GLX_USE_TLS is defined, or pthread, if PTHREADS is defined. If none of them are defined, it uses a dummy implementation that is just like before. Signed-off-by: Chia-I Wu <[email protected]>
